Snow Water Ice and Water and Adaptive Actions for a Changing Arctic

The Arctic is changing fast, and the Arctic Council recently commissioned the Arctic Monitoring and Assessment Programme (AMAP) to write two new reports on the state of the Arctic cryosphere (snow, water, and ice) and how the people and the ecosystems in the Arctic can live with these changes.

The two reports have now just been published and are called Snow Water Ice and Permafrost in the Arctic Update (SWIPA-update) and Adaptive Actions for a Changing Arctic (AACA).

I can see why these reports can be a bit confusion, with two reports released at the same time by the same organisation. Actually, there are four parts.

The AACA report consists of three regional reports with an emphasis on the Baffin Bay/Davis Strait region, the Barents region, and the Bering/Beaufort/Chukchi region.

The writing process has involved scientists from the US, Canada, Germany, Russia, Finland, Sweden, Denmark, and Norway.

The message from these reports is that the Arctic temperatures increase rapidly, in line with the notion of ‘polar amplification’.

The increased temperatures have been accompanied with changes in snow, sea-ice, precipitation, permafrost, icebergs, landice, river runoff, polar lows, synoptic storms, cloudiness, avalanches, ocean circulation, and ocean acidification.

For some of these aspects, there have been clear evidence for changes, such as precipitation, snow, ice, and permafrost. For others, such as polar lows, synoptic storms, and cloudiness, the evidence is more ambiguous.

The number of polar lows and the frequency of fog over the Barents sea, however are believed to diminish as the sea ice cover retreats.

The changing conditions in the Arctic have an impact on both the ecosystems and the people living there.

The AACA report covers social sciences in addition to the atmosphere, the Arctic ocean, and the cryosphere. It provides an update since the Arctic Climate Impact Assessment (ACIA) from 2004 and the Intergovernmental Panel on Climate Change (IPCC) reports.

The full reports are still not public, so it is only the summaries that are publicly available at the moment. I expect the full reports to be publicly available some time this summer.

I can see why some people think it’s strange that the summary comes before the report, and this has also been an issue with the assessment reports from the IPCC.

Personally, I think it’s better to wait with the summary until everything is ready to avoid misunderstandings about the report writing process. The main reports are more or less finished and it is just the final quality control and checking that remain.

This Earth Month, we’re excited to present our 2017 restoration projects with our long-time partner, Alcoa Foundation. The project announcement coincides with more news American Forests is also thrilled to release: a new, three-year partnership with Alcoa Foundation to enhance biodiversity and combat climate change in key areas across the globe!

Check out footage from our 2016 project in Pittsburgh, Penn., below.

In the new partnership’s first year alone, American Forests will work with partners to restore over 140 acres in 11 locations while engaging 2,500 volunteers. Here is a brief look at our 2017 projects:

Location: Patoka River National Wildlife Refuge, Indiana, USA
Local Partner: Friends of the Patoka River National Wildlife Refuge

More than 16,000 native hardwood trees will be planted on 30 acres on two recently acquired properties. In addition to tree planting on the refuge, invasive tree species will be removed from 5 acres of oak savannah on the Columbia Mine Preserve owned by the Sycamore Land Trust. Removing the invasive trees will allow native oaks and important pollinator plants to thrive, while the removed invasive trees will be added to nearby lakes for fish habitat.

Location: Massena, New York, USA
Local Partner: Town of Massena Electric Department

The Electric Department will engage volunteers to plant 100 larger-stock trees including red maple, sugar maple, northern red oak and flowering crabapple in underserved neighborhoods based on the community’s strategic forest plan. Additionally, 1,250 seedlings will be planted on a recently closed sand mining site within the community, improving environmental conditions for residents and local wildlife.

Location: Pittsburgh, Pennsylvania, USA
Local Partner: Tree Pittsburgh

Building on momentum and interest from last year’s tree planting project, Tree Pittsburgh will plant 2,000 trees on 5 acres of land in a two-year project. Planting trees will help to recover nearly 10,000 acres of tree cover lost in Pennsylvania’s Allegheny County over the past five years from residential and commercial development, and the loss of many ash trees due to emerald ash borer, an invasive pest.

Location: Whatcom County, Washington, USA
Local Partner: Nooksack Salmon Enhancement Association

A community engagement powerhouse, the Nooksack Salmon Enhancement Association (NSEA) will work with 10 community partners to identify degraded stream sides along salmon-bearing waterways and host 15 volunteer work parties to restore them. Planting native trees provides salmon various ecosystem benefits, such as bank stabilization, improved water clarity, detritus input, cooling shade and higher dissolved oxygen. These work parties are expected to engage 2,000 volunteers that will plant 6,000 native trees and shrubs.

Locations: Madrid, Avilés, A Coruña, and San Ciprián, Spain
Local Partner: Ecoherencia

Ecoherencia will host four volunteer tree planting events in different locations across Spain. These events are expected to attract over 200 volunteers in total that will plant 1,800 trees native to the Iberian Peninsula. Reforestation with native trees and other understory plants will aid in the recovery of Spain’s unique habitats, combat desertification and mitigate the effects of climate change.

Locations: Eskifjörður and Úlfljótsvatn, Iceland
Local Partner: Icelandic Forestry Association

With local partners, we will plant 7,500 trees in Eskifjörður and Úlfljótsvatn — east and southwest Iceland, respectively — in a collaborative effort between the Icelandic Forestry Association and Eskifjörður Forestry Association. Reforestation in Iceland will also help stabilize easily eroded soils composed of volcanic ash and capture ash and tephra from new volcanic eruptions, which are common here.

Location: São Luís, Maranhão, Brazil
Local Partner: Escola Casa Familiar Rural

Tropical rainforest deforestation pollutes rivers and other important drinking water sources, contributes to wildfire risk, and fosters a general lack of appreciation for the environment. To address these compounding issues, Escola Casa Familiar Rural will construct a native plant nursery at their school in São Luís, which is expected to annually produce 500 tree seedlings that will be given away at no cost to the community.

Location: São Luís, Maranhão, Brazil
Local Partner: Escola Casa Familiar Rural

All bauxite ore produced at Alcoa’s Juruti mine is transported 50 kilometers by train to the port every day. In 2017, the second phase of their project, the Vitoria Regia Institute seeks to offset the train’s carbon emissions by restoring tropical rainforest near Juruti and inventorying the sequestered carbon. Past work has shown that each native tree of the Atlantic Forest sequesters 315 kilograms of carbon in 20 years.

Location: Poços de Caldas, Minas Gerais, Brazil
Local Partner: Associacao Pocos Sustentavel

Small forests in urban areas are disproportionally important to people for the recreational opportunities and thermal comfort they provide, among other benefits. Associacao Pocos Sustentavel seeks to reclaim and restore open spaces in Poços de Caldas with plant species native to the Atlantic Forest ecosystem. Working in collaboration with Brazilian Botanic Gardens Network, seeds from native plants will be collected and catalogued as part of a scientific conservation effort.

Location: São Paulo, Brazil
Local Partner: Associação Corredor Ecológico do Vale do Paraíba (ACEVP)

The Atlantic Forest contains more than 20,000 plant species and some 2,200 animal species, many of them found nowhere else. Yet, only 10 percent of the original forest remains. To help restore this natural treasure, ACEVP will plant 4,690 native trees in strategic locations, employing agroforestry techniques where possible to simultaneously restore forest functions and support private landowners.

Location: Quebec, Canada
Local Partner: Comité de Zones d’Interventions Prioritaires Les Deux Rives

St. Paul Lake contains a rich diversity of fish species and aquatic plants, but water pollution from nearby farms is degrading water and threatening this biodiversity. To restore water quality in the lake and St. Lawrence River watershed, 9,000 trees will be planted along 9 kilometers of shoreline and tributaries. Comité de Zones d’Interventions Prioritaires Les Deux Rives will work with 10 farmers to restore the riparian areas.

Keep checking back with us on Loose Leaf or by following us on Facebook, Twitter and Instagram, as we will be highlighting each of these projects throughout the year!

New Projects Will Enhance Biodiversity and Combat Climate Change

Washington, D.C. (April 26, 2017) — American Forests and Alcoa Foundation announce a new, three-year partnership to enhance biodiversity and combat climate change in key areas across the globe.

In year one, American Forests will engage 2,500 volunteers and restore more than 140 acres in 11 locations, including cold-water streams in the Pacific Northwest, Brazil’s Amazon Forest, and riparian forests in northern Spain,

In Bellingham, Wash., American Forests will also continue its partnership with the Nooksack Salmon Enhancement Association (NSEA) to restore degraded watersheds. Over the past decade, salmon populations throughout the region have declined drastically and local stocks of Chinook salmon and steelhead have been listed as threatened under the Endangered Species Act. NSEA will create volunteer work parties to restore 10 acres of key watershed habitat that cools local streams and helps restore populations.

In Juruti, Brazil, American Forests will continue its partnership with the Vitoria Regia Institute to calculate and offset carbon emissions generated by local trains that transport mine materials from the local Alcoa facility. The institute will work with local landowners and engage volunteers to offset emissions by reforesting 50 acres of native wildlife habitat

Along the northern coast of Spain, American Forest will support Ecoherencia’s efforts to restore riparian forests in Fragas do Eume National Park, engage volunteers and provide environmental education to students.

“Over the next three years, Alcoa Foundation will be working with American Forests to demonstrate our commitment to our employees and to communities around the world to make a positive and long-lasting impact on our shared environment,” said Rosa García Pineiro, Alcoa Foundation President and Sustainability Vice President.

Since 2011, Alcoa Foundation and American Forests have worked together to enhance and protect forests in 14 countries, restoring wildlife habitat and combating climate change by utilizing forests to augment carbon storage and purify water and air. Through the dedication of Alcoa employees, local communities and partners, more than 1.58 million trees have already been planted.

“The Alcoa Foundation and American Forests have been partners on dozens of restoration projects during the past six years,” said Scott Steen, president & CEO of American Forests. “We are excited to take our partnership to the next level with a new, three-year commitment to enhance biodiversity and combat climate change.”

Joining Forces to Double Longleaf Pine Forests by 2024

April 24th, 2017|Tags: , , , |0 Comments

By Eric Sprague, Director of Forest Conservation

You probably see trees everywhere you go: along the road as you drive to work, the woods you pass while walking the dog, or the large stretches of forests you drive through on your way to a national park. However, this apparent abundance can be deceiving.

America’s forests are increasingly being chopped up into smaller and smaller areas by development, roads, utility lines and other land uses. As forest is lost, new gaps are created that can cause a host of problems. This activity creates new entry points for invasive plants and pests, introduces sources of wildfire, and allows severe weather and noise to access further into the interior of the forest. These and other associated stressors reduce the overall quality of habitat and ability of forests to provide the natural benefits that we rely on, such as clean air and water.

The loss of habitat and its decline in health is the major threat to North America’s wildlife, including the gopher tortoise. The gopher tortoise is one of four North American tortoises and ranges from far southeastern Louisiana to southern South Carolina and down to the Everglades in Florida.

The tortoise digs extensive burrows that can be up to 50 feet in length and 10 feet deep. These burrows in turn provide shelter for 360 other kinds of animals. When not keeping cool in their underground homes, gopher tortoises like to graze grasses in surrounding habitat — the favorite of which is longleaf pine forests.

This fire-adapted ecosystem used to cover 90 million acres across the Southeastern U.S. Today, longleaf pine forests cover just 3 percent of their former range — a staggering reduction that more than rivals well-known losses in southeastern wetland and world rainforest habitats.

The changing nature of these forests is a real challenge to the gopher tortoise and nearly 600 other species adapted to life in and under longleaf pines. The gopher tortoise is federally listed as threatened under the Endangered Species Act west of the Mobile and Tombigbee Rivers in Alabama. East of these rivers, the tortoise is a candidate species, as the U.S. Fish and Wildlife Service found that listing was warranted, but precluded because they were focusing on higher priority species.

Through the Wildlands for Wildlife initiative, American Forests is working with our partners to restore longleaf pine ecosystems and gopher tortoise populations. In collaboration with the U.S. Forest Service and the Longleaf Alliance, American Forests is kick-starting a five-year effort in South Carolina to reintroduce gopher tortoises and other key species into new habitats on permanently protected private lands that are managed for the species. In 2017, this will include collecting and hatching 100 gopher tortoise eggs to raise for release. Also, 95,000 longleaf pines are will be planted to restore more than 200 acres of habitat.

In Alabama’s Talladega National Forest, the five-year plan is to complete a 10,000-acre longleaf restoration project. In 2017, nearly 90,000 longleaf pines will be planted, existing loblolly and slash pine plantations will be converted to biodiverse longleaf ecosystems and prescribed burns will be conducted to support those ecosystems.

In Mississippi’s De Soto National Forest, we will work with partners to plant 100,000 longleaf pines in a core restoration area for the endangered gopher tortoise population.

A diverse group of partners have created a plan to bring back longleaf pine ecosystems. By 2024, the goal of America’s Longleaf Restoration Initiative is to expand the area of longleaf forests from the existing 4 million acres to 8 million. American Forests is committed to helping to achieve this goal by restoring key habitat strongholds on public lands and creating new habitat on private lands.

Vote for the Southeastern U.S.

Do you live in or near the Southeastern U.S., or enjoy the gopher tortoise? Then vote today or by 10:00 a.m. EDT on April 26, and the winning region will receive an additional $10,000 project investment in 2018!

What Earth Day Means to Us

April 21st, 2017|Tags: |0 Comments

.fusion-fullwidth-1 {
padding-left: px !important;
padding-right: px !important;
}

Have you ever been interested in who it is working behind the scenes to advance conservation and restoration with American Forests? We’d like to share with you what Earth Day means to some of us here at American Forests, and why we think this important day needs to be recognized. We asked our staff a number of questions — about the environment, about their childhood memories of nature, and of Earth Day itself, and this is what they had to say.

Scott Steen, President & CEO

Scott is fascinated by the origins of Earth Day. “I loved learning about the history of how Earth Day came into being,” he shares. “The first Earth Day in 1970 brought together Republicans and Democrats, young and old, urban and rural, and rich and poor in a rare moment of common understanding of what was being lost and how quickly we were losing it. At that moment in our history as a nation, the desire to create a safe and healthy environment for our children transcended ideology. People saw protecting wilderness and wildlife habitat as a part of both preserving our heritage and providing a legacy for future generations. As a result, the movement that grew out of that first Earth Day had a significant impact on the creation of the U.S. Environmental Protection Agency and the passage of the Clean Air, Clean Water and Endangered Species Acts.”

Ellie Parrish, Manager of Development

Ellie’s plans are to do a big hike somewhere she’s never been on Earth Day, hopefully on the Appalachian Trail, but for her Earth Day really calls to mind all the work she’s done planting trees. “I planted trees at people’s homes for a living,” she says. “I love looking at the before and after photos. Trees are such a radically positive change everywhere they are planted, particularly in urban landscapes!”

Lea Sloan, Vice President of Communications

Lea is known at American Forests for having a deep appreciation for the natural history imbued in our surroundings, and also for the incomparable value to be found in our wildernesses. “It’s easy to take our most vital resource for granted,” she begins, “when we’re able to breathe clean air, drink clean water and access nourishing food grown in healthy soil. Earth day is a celebration of those essentials but also a reminder that we need to defend it — from being overrun by human population, unchecked development and industrialization that collectively all threaten to choke the integrity of the elements that all life depends on.”

Forest restoration is something Lea truly breathes 24/7, day in and day out. “I have planted many trees, including a dozen or so in our own backyard that I have had the opportunity to witness grow. It makes me feel good to set those roots into the ground — I feel renewed afterwards, like I’ve been meditating or swimming in a wild or beautiful place. It also is a bit like extending one’s own mortality by giving life to something that could outlive you by 100 — or 500 years…”

Maverick Ryan, Policy Intern

Our intern Maverick really takes the time to think about the meaning of this special day. “To me, it represents a day for the unification of every aspect of respecting our Earth,” he begins. “For a single day we can all agree that the one thing tying all of our perceptions and resources together is their presence on Earth. Additionally it’s just a cool moment to identify and respect all of the mutually reliant relationships that exist within our ecosystems. It’s kind of humbling once you realize as a human how much people rely on the landscape, even though they don’t think about it.”

Maverick Ryan

He dreams about really getting out into the wilderness, this Earth Day. “I’d love to situate a 10-15 day hike across the Olympic National Park in Washington State so that Earth Day falls right in the middle. That way I could really contemplate my relationship with our Earth in a place symbolic of what the Earth was like before humankind carved it up.”

Lindsey Huerter, Director of Corporate Giving

Earth Day brings up childhood memories for Lindsey, who told us about a particularly charming one involving her mother. “One of my favorite memories of planting began early in my childhood,” she says. “My mom had shown me a picture of what the lilac bush we were putting in the ground would look like in the future. I was sorely disappointed when what she brought home to plant appeared nothing like the image I had seen. She explained to me how this plant would need my love and nurturing to blossom. Over the next few years I went through the motions of caring for the plant, impatiently waiting for the purple flowers I was promised. The moment the plant bloomed was that much more special because of the attention I had given it. I think this is a lesson we can all remind ourselves of during Earth Month. The more we care for the earth, the more we will appreciate its beauty.”

Doyle Irvin, Communications Intern

Doyle is generally confused, when it comes to Earth Day. “My parents are born one year and one day apart,” he begins. “And for the longest time, growing up, I couldn’t remember if it was April 21 and 22 or April 22 and 23. 1957 and 1958, or ’58 and ’59? All I could keep together was that one of them was on Earth Day and that I was a neglectful son and should pay more attention. On top of that, because they live in two different places, that weekend would always be a logistical mess. Neither of them are at all easy to find gifts for, either. Then, to add even more complexity into the mix for a kid to deal with, my own birthday was a week later. Talk about divided loyalties and attention. So, for me — and it’s kind of awful — Earth Day really reminds me of how difficult it is to get it right, how each generation is tied to the next and responsible for it, how we have to be mindful and put our own immediate satisfaction on the backburner. When you think about all of the different ways that we as humans negatively impact the environment, and all of the different problems around the world, it can be really difficult to know where to start.”

Ian Leahy, Director of Urban Forests

Ian is pretty hardcore, when it comes to Earth Day. “I have mixed feelings about Earth Day,” he begins. “Whenever we designate a time to celebrate some entity, it’s often a sign something has gone horribly wrong at some point. I’ve been to Earth Day celebrations where paper plates were strewn across the field afterwards, bottled water was distributed with abandon and the most people were encouraged to do was wear green. So, clearly there’s still a lot of work left to do! I look forward to living the cliché, ‘every day is Earth Day!’”

It’s not all grim for Ian, though. A few years back, while directing a Community ReLeaf planting, the local volunteers nicknamed him “John Henry” from all the hammering he did, staking the ground to support the young saplings being planted. “On a recent trip, I revisited the site,” Ian says. “I saw kids walking home from school, having fun, playing in the green space alongside the trail (and trying to recover a basketball they’d accidentally thrown into the adjacent canal). It felt good to see. A successful urban forest melds seamlessly into the everyday lives of the residents.”

Christopher Horn, Director of Communications

For Christopher, Earth Day is a time to reflect. “I know for many people, Earth Day is a time to get involved in environmental activism or volunteer in your community — I like to plant a tree or do a river clean-up, myself! For me, though, Earth Day presents an opportunity to re-center myself with nature and reflect on why I do what I do. Being grounded in the Earth helps me stay focused when challenges arise. Ever since childhood, I’ve considered my Earth Day wilderness excursions to be little retreats for my tree-hugging soul!”

Lindsey Miller-Voss, Social Media Manager

For Lindsey, Earth Day is all about community. “Earth Day is a great opportunity to get everyone really excited about what they can do for the planet,” she says. “It’s wonderful to have a special day set aside to really reflect on the status of our ecosystems, wildlife, and environment as a whole. I really enjoy celebrating Earth Day with my daughter. As she’s gotten older our projects have gotten more involved, from planting seeds and park visits, to planning our summer gardens and hikes in the woods. I’d love to attend one of the larger Earth Day festivals around the country, like the Earth Day Roanoke Festival in Roanoke, Virginia or EarthFest in Knoxville, Tennessee. EarthFest typically has over 5,000 people attend and is such an impressive gathering for the planet — they only produce an average of 10 pounds of trash, total!”

And here’s a photo of Justin Hynicka, Forest Conservation Manager, for good measure:

  • Status of forests is ‘dire’ as world marks 2017 Earth DayLos Angeles Times
    According to the World Bank development indicators from 2016, the world has lost 1,000 football fields of forests every hour since 1990. That’s 1.3 million square kilometers of forest, which is an area larger than South Africa. Especially with Earth Day coming up tomorrow, we should emphasize the message that forest protection is more critical than ever.
  • Denver Trees Are Turning Green, But Also Blue — CBS Denver
    Volunteers are in the process of painting trees in downtown Denver blue (of course, using environmentally safe colorant). The art project, Blue Trees, aims to inspire a community conversation about deforestation. Over the next six weeks, the volunteers will color 150 trees in Denver’s theater district.
  • California Democrats prepare to battle GOP over Endangered Species ActThe Mercury News
    House Republicans recently held a hearing to make the case that the Endangered Species Act needed serious improvements and hindering efforts to repair dams, roadways and bridges. At the same time, lawmakers in California have been working to strengthen their state’s protections for endangered species, should they lose federal protection. The California Democrats are currently moving the California Environmental, Public Health, and Workers Defense Act of 2017 through the Legislature. This act would toughen environmental regulations signed by Nixon in the 70s.
  • Prescribed forest fire frequency should be based on land management goalsScience Daily
    In a 68-year study, researchers at the University of Missouri studied forests subjected to different frequencies of fire to determine the effects that fire can have on oak forests over long period of time. They found that the frequency of prescribed forest fires should be determined based on the long-term goals of land managers.
  • The trees that make Southern California shady and green are dying. Fast.Los Angeles Times
    The trees that shade, cool and feed Southern Californians are dying so fast that within a few years, the region may look nothing like it does now. Greg McPherson, a supervisory research forester with the U.S. Forest Service, estimates that even just one type of insect, the polyphagous shot hole borer beetle, could kill up to 27 million trees in the area. That’s roughly 38% of the 71 million trees in the 4,244 square mile urban region with a population of about 20 million people.

With Earth Day just a few days away, you might be wondering how you can get involved in helping our environment and conserving forests. Likewise, the shifting of the winds in politics today may also make you unsure of how to respond to the legislative measures that could impact our environment and the people and wildlife that depend on it.

Whether you plan to attend an upcoming climate march in your city or state, our Action Center is another way to let your voice be heard! Credit: Garry Knight

Calling your elected officials and reaching out to them at town hall events are good ways to voice your opinion, and our Action Center is another way to do it!

Keeping up-to-date with everything happening on the Hill is crucial to playing an active role in shaping the policy that affects all of our lives, and alerts in the Action Center will help you achieve that. In addition, our Action Alerts can be sent right to your email so you know exactly when your voice is needed. Through our revamped Action Center, you will learn the latest plans our government has for our forests and voice your opinion to your congressional representatives, the administration, and others with only a few clicks of your mouse!

It has become abundantly clear from these first few months that the new presidential administration is intent on changing the nature of public lands, environmental regulations, and the energy industry at an increasingly rapid pace. This not only decreases the volume of analysis and review that can be accomplished before a new law passes or fails, it also means we have a smaller amount of time to make our collective voice heard on the issue. Our Action Center and alerts offers you a way to keep up with this faster pace by summarizing a new action in Congress, the administration, or state and local events for you, describing its expected effect on forests, and calling on you to advocate through a personalized letter sent to lawmakers and policy decision-makers. We hope this streamlines the process for each of you by combining the information you need and the chance to let the lawmakers know your position. Come see our newest initiatives, and help us make sure things like the Endangered Species Act are defended for our generation and those that will come after us!

Theodore Roosevelt lived his life by the mantra, “Do what you can, with what you have, where you are.” With his words in mind, the Action Center is where you’ll find what you can do in response to what’s going on in government. As one of the founding fathers of modern conservation, Roosevelt managed to convince an entire country that forests are worth fighting for and that government agencies can lead that fight. Now, a new administration needs to hear that we stand with those who came before us and are committed to the programs, organizations, and projects that protect and restore our forests.

I try not to let the weather dictate my camping plans. Even so, the bleak weather forecast had me hedging on a trip to Dolly Sods Wilderness in West Virginia’s Monongahela National Forest three weeks ago. It is one of the closest wilderness areas to our nation’s capital and because it is such a spectacular place, I was ultimately convinced to stick to the original plan. Three hours later (sans traffic) and… the access road is still closed for the season. Down here it’s overcast and drizzling but not too cold, so we joined the other half-dozen or so cars on the side of the road, donned our backpacks and took to the road on foot.

At the top of Dolly Sods on this day, it is downright unpleasant. It’s cold, windy and raining, and because of the rain there is about 3 inches of standing water everywhere. Fifteen-foot-tall red spruce growing closely together along the swollen stream are the only windbreak in sight in this otherwise rocky and blueberry-laden landscape, so we scavenge among the spruce for a flat spot with as little standing water as possible and pitch our tent.

Although still spectacular in its current state, it’s hard to fathom that just over 100 years ago Dolly Sods was part of an extensive 500,000-acre, old-growth red spruce forest capping the highlands of Appalachia. To start, the ground would have been much softer with up to 9 feet of leaves and other organic matter blanketing the ground as both the weather and spruce leaf chemistry lead to slow rates of decomposition. Now largely gone, this thick layer of organic matter made a lasting impression on the landscape that is easily visible today by bleaching lower soil layers white with natural organic acids and giving streams in this region their characteristic amber color as spruce and hemlock leaves were broken down into soluble tannins. For this reason, restoring red spruce is one of our strongest carbon-sequestration projects.

Both old trees and organic-rich soils are important for West Virginia northern flying squirrel habitat. The typical red spruce can grow 60 to 90 feet tall with a trunk 2 to 4 feet in diameter. In winter, groups of squirrels share nests in tree cavities previously constructed by woodpeckers, while in summer they are more likely to nest in branches at the tops of spruce trees that they glide to and fro on flaps of extra skin between their front and back legs. Fungi are abundant in the organic rich soils and are eaten by the squirrels, which in-turn help disperse fungal spores throughout the forest.

Due to habitat loss, the West Virginia northern flying squirrel was listed under the Endangered Species Act in 1985, but was subsequently and controversially de-listed in 2013 despite limited population data.

Along with more than 9 million acres of other virgin forest in West Virginia, red spruce forests were felled in an abrupt 40-year span between 1880 and 1920 in a perfect storm of forest technology innovation. The Shay geared locomotive provided access in and out of the rugged terrain, while the ban saw provided the firepower to efficiently cut the felled trees up. Band saw mills could process trees from up to 17 acres of virgin forest DAILY! At the peak of the timber industry, 83 band saw mills were in operation along with over 1,400 other facilities (Logging of West Virginia Forests).

Only 5 percent of old-growth red spruce forests remain today but there are multiple efforts underway to help recover this diverse forest ecosystem. To date, American Forests has helped to restore 941 acres of red spruce forest by planting 157,465 trees. In 2017, we will plant an additional 200 acres with 75,000 red spruce and other native plants on abandoned mine land where, without restoration, trees cannot grow. This work is part of a collective 10-year effort including American Forests and other groups from the Central Appalachian Spruce Restoration Initiative (CASRI) to remake an entire mountain by de-compacting former mine lands, planting new trees, creating wetlands and thinning over-stocked red spruce forests to improve forest health.

In two weeks, American Forests staff will be on an overnight adventure to plant red spruce trees in Monongahela National Forest. My fingers are crossed for good weather.

Judy Curry’s attribution non-argument

Following on from the ‘interesting’ House Science Committee hearing two weeks ago, there was an excellent rebuttal curated by ClimateFeedback of the unsupported and often-times misleading claims from the majority witnesses. In response, Judy Curry has (yet again) declared herself unconvinced by the evidence for a dominant role for human forcing of recent climate changes. And as before she fails to give any quantitative argument to support her contention that human drivers are not the dominant cause of recent trends.

Her reasoning consists of a small number of plausible sounding, but ultimately unconvincing issues that are nonetheless worth diving into. She summarizes her claims in the following comment:

… They use models that are tuned to the period of interest, which should disqualify them from be used in attribution study for the same period (circular reasoning, and all that). The attribution studies fail to account for the large multi-decadal (and longer) oscillations in the ocean, which have been estimated to account for 20% to 40% to 50% to 100% of the recent warming. The models fail to account for solar indirect effects that have been hypothesized to be important. And finally, the CMIP5 climate models used values of aerosol forcing that are now thought to be far too large.

These claims are either wrong or simply don’t have the implications she claims. Let’s go through them one more time.

1) Models are NOT tuned [for the late 20th C/21st C warming] and using them for attribution is NOT circular reasoning.

Curry’s claim is wrong on at least two levels. The “models used” (otherwise known as the CMIP5 ensemble) were *not* tuned for consistency for the period of interest (the 1950-2010 trend is what was highlighted in the IPCC reports, about 0.8ºC warming) and the evidence is obvious from the fact that the trends in the individual model simulations over this period go from 0.35 to 1.29ºC! (or 0.84±0.45ºC (95% envelope)).


Ask yourself one question: Were these models tuned to the observed values?

Second, this is not how the attribution is done in any case. What actually happens is that the fingerprint of different forcings are calculated independently of the historical runs (using subsets of the drivers) and then matched to the observations using scalings for the patterns generated. Scaling factors near 1 imply that the models’ expected fingerprints fit reasonably well to the observations. If the models are too sensitive or not enough, that will come out in the factors, since the patterns themselves are reasonably robust. So models that have half the observed trend, or twice as much, can still help determine the pattern of change associated with the drivers. The attribution to the driver is based on the best fits of that pattern and others, not on the mean or trend in the historical runs.

2) Attribution studies DO account for low-frequency internal variability

Patterns of variability that don’t match the predicted fingerprints from the examined drivers (the ‘residuals’) can be large – especially on short-time scales, and look in most cases like the modes of internal variability that we’ve been used to; ENSO/PDO, the North Atlantic multidecadal oscillation etc. But the crucial thing is that these residuals have small trends compared to the trends from the external drivers. We can also put these modes directly into the analysis with little overall difference to the results.

3) No credible study has suggested that ocean oscillations can account for the long-term trends

The key observation here is the increase in ocean heat content over the last half century (the figure below shows three estimates of the changes since 1955). This absolutely means that more energy has been coming into the system than leaving.

Now this presents a real problem for claims that ocean variability is the main driver. To see why, note that ocean dynamics changes only move energy around – to warm somewhere, they have to cool somewhere else. So posit an initial dynamic change of ocean circulation that warms the surface (and cools below or in other regions). To bring more energy into the system, that surface warming would have to cause the top-of-the-atmosphere radiation balance to change positively, but that would add to warming, amplifying the initial perturbation and leading to a runaway instability. There are really good reasons to think this is unphysical.

Remember too that ocean heat content increases were a predicted consequence of GHG-driven warming well before the ocean data was clear enough to demonstrate it.

4) Indirect effects of solar forcing cannot explain recent trends

Solar activity impacts on climate are a fascinating topic, and encompass direct radiative processes, indirect effects via atmospheric chemistry and (potentially) aerosol formation effects. Much work is being done on improving the realism of such effects – particularly through ozone chemistry (which enhances the signal), and aerosol pathways (which don’t appear to have much of a global effect i.e. Dunne et al. (2016)). However, attribution of post 1950 warming to solar activity is tricky (i.e. impossible), because solar activity has declined (slightly) over that time:

5) Aerosol forcings are indeed uncertain, but this does not impact the attribution of recent trends very much.

One of the trickier issues for fingerprint studies is distinguishing between the patterns from anthropogenic aerosols and greenhouse gases. While the hemispheric asymmetries are slightly larger for aerosols, the overall surface pattern is quite similar to that for greenhouse gases (albeit with a different sign). This is one of the reasons why the most confident statements in IPCC are made with respect to the “Anthropogenic” changes all together since that doesn’t require parsing out the (opposing) factors of GHGs and aerosols. Therefore in a fingerprint study that doesn’t distinguish between aerosols and GHGs, what the exact value of the aerosol forcing right is basically irrelevant. If any specific model is getting it badly wrong, that will simply manifest through a scaling factor very different from 1 without changing the total attribution.

What would it actually take to make a real argument?

As I’ve been asking for almost three years, it is way past time for Curry to shore up her claims in a quantitative way. I doubt that this is actually possible, but if one was to make the attempt these are the kind of things needed:

  • Evidence that models underestimate internal variability at ~50-80 yr timescales by a factor of ~5.
  • Evidence that indirect solar forcing can increase the long-term impact of solar by a factor of 3 on centennial time-scales or reverse the sign of the forcing on 50-80 yr timescales (one or the other, both would be tricky!).
  • Evidence that warm surface ocean oscillations are associated with increased downward net radiation at the TOA. [This is particularly hard because it would mean the climate was fundamentally unstable].
  • Evidence that the known fingerprints of different forcings are fundamentally wrong. Say, that CO2 does not cool the stratosphere, or that solar forcing doesn’t warm it.

Absent any evidence to support these statements, the claim that somehow, somewhere the straightforward and predictive mainstream conclusions are fundamentally wrong just isn’t credible.
