Emerging consensus shows climate change is already having major effects on ecosystems and species

December 2012. Plant and animal species are shifting their geographic ranges and the timing of their life events – such as flowering, laying eggs or migrating – at faster rates than researchers documented just a few years ago, according to a technical report on biodiversity and ecosystems used as scientific input for the 2013 Third National Climate Assessment.

The report, Impacts of Climate Change on Biodiversity, Ecosystems, and Ecosystem Services, synthesizes the scientific understanding of the way climate change is affecting ecosystems, ecosystem services and the diversity of species, as well as what strategies might be used by natural resource practitioners to decrease current and future risks. More than 60 US federal, academic and other scientists, including the lead authors from the U.S. Geological Survey, the National Wildlife Federation and Arizona State University in Tempe, authored the assessment.

Wide-ranging change to ecosystems
"These geographic range and timing changes are causing cascading effects that extend through ecosystems, bringing together species that haven't previously interacted and creating mismatches between animals and their food sources," said Nancy Grimm, a scientist at ASU and a lead author of the report.

Other key findings of the report include:

Changes in precipitation and extreme weather events can overwhelm the ability of natural systems to reduce or prevent harm to people from these events. For example, more frequent heavy rainfall events increase the movement of nutrients and pollutants to downstream ecosystems, likely resulting not only in ecosystem change, but also in adverse changes in the quality of drinking water and a greater risk of waterborne-disease outbreaks. Changes in winter have big and surprising effects on ecosystems and their services. Changes in soil freezing, snow cover and air temperature affect the ability of ecosystems to store carbon, which, in turn, influences agricultural and forest production. Seasonally snow-covered regions are especially susceptible to climate change because small precipitation or temperature shifts can cause large ecosystem changes. Longer growing seasons and warmer winters are already increasing the likelihood of pest outbreaks, leading to tree mortality and more intense, extensive fires. Decreased or unreliable snowfall for winter sports and recreation will likely cause high future economic losses. The ecosystem services provided by coastal habitats are especially vulnerable to sea-level rise and more severe storms. The Atlantic and Gulf of Mexico coasts are most vulnerable to the loss of coastal protection services provided by wetlands and coral reefs. Along the Pacific coast, long-term dune erosion caused by increasing wave heights is projected to cause problems for communities and for recreational beach activities. However, other kinds of recreation will probably improve due to better weather, with the net effect being that visitors and tourism dollars will shift away from some communities in favour of others. Climate change adaptation strategies are vital for the conservation of diverse species and effective natural resource policy and management. As more adaptive management approaches are developed, resource managers can enhance the country's ability to respond to the impacts of climate change through forward-looking and climate science-informed goals and actions. Ecological monitoring needs to be improved and better coordinated among federal and state agencies to ensure the impacts of climate change are adequately monitored and to support ecological research, management, assessment and policy. Existing tracking networks in the United States will need to improve coverage through time and in geographic area to detect and track climate-induced shifts in ecosystems and species.

NOAA proposes listing 66 reef-building coral species under the Endangered Species Act

NOAA press release: November 30, 2012

In compliance with a federal court ordered deadline, and consistent with existing international protections, NOAA Fisheries announced today that it is proposing Endangered Species Act (ESA) listings for 66 coral species, including 59 in the Pacific and seven in the Caribbean. This science-based proposal is more limited than the 2009 original petition that led to a settlement agreement and the court order. In order to ensure robust input, NOAA has been engaging the public since the process began three years ago. Before this proposed listing is finalized in late 2013, there will be a 90-day public comment period during which NOAA will hold 18 public meetings.

Earlier this year, the President directed that any potential future designations of critical habitat carefully consider all public comments on relevant science and economic impact, including those that suggest methods for minimizing regulatory burdens. Therefore, any potential future critical habitat designation in connection with today’s proposed listing will include a full analysis of economic impact, including impact on jobs, and to the extent permitted by law, adopt the least burdensome means, including avoidance of unnecessary burdens and costs on states, tribes, localities, and the private sector of promoting compliance with the ESA. As this process moves forward, NOAA will work with stakeholders to minimize any potential impacts of possible future action on the economy and jobs and, in particular, on construction, fishing, farming, shipping, and other important sectors.

“Healthy coral reefs are among the most economically valuable and biologically diverse ecosystems on earth,” said Jane Lubchenco, Ph.D., under secretary for commerce for oceans and atmosphere and NOAA administrator. “Corals provide habitat to support fisheries that feed millions of people; generate jobs and income to local economies through recreation, tourism, and fisheries; and protect coastlines from storms and erosion. Yet, scientific research indicates that climate change and other activities are putting these corals at risk. This is an important, sensible next step toward preserving the benefits provided by these species, both now and into the future.”

NOAA is proposing seven species as endangered and 52 as threatened in the Pacific, and five as endangered and two as threatened in the Caribbean. In addition, the agency is proposing that two Caribbean species already listed under the Act be reclassified from threatened to endangered. NOAA is seeking public comment on the proposed listing before making a final listing decision by December 2013.

Corals have measurable economic value for communities around the world. One independent study reported that coral reefs provide approximate $483 million in annual net benefit to the U.S. economy from tourism and recreation activities and a combined annual net benefit from all goods and services of about $1.1 billion. NOAA also estimates the annual commercial value of U.S. fisheries from coral reefs to be more than $100 million; reef-based recreational fisheries generate an additional $100 million annually.

Listing species as endangered does not prohibit activities like fishing or diving, but prohibits the specific “take” of those species, including harming, wounding, killing, or collecting the species. It also prohibits imports, exports, and commercial activities dealing in the species. These protections are not automatic for species listed as threatened, but can be established for them as well. Furthermore, if species are eventually listed, NOAA will consult with other federal agencies that permit projects that may harm corals to help avoid further damage. The consultation process allows NOAA to work with federal agencies and project proponents to develop ways for projects to proceed, but in a way that protects the long-term health of these important species.

NOAA has identified 19 threats to the survival of coral, including rising ocean temperatures, ocean acidification, and coral disease. As carbon dioxide increases in the atmosphere, the oceans warm beyond what corals can withstand, leading to bleaching, and the frequency and severity of disease outbreaks increase, causing die-offs.

This proposed listing is in response to a 2009 petition from the Center for Biological Diversity (CBD) to list 83 coral species as threatened or endangered under the ESA. In 2011, NOAA and the CBD entered into a stipulated settlement agreement requiring NOAA to submit for publication a proposal as to 82 of the 83 coral species by April 15, 2012. In March 2012, the District Court for the Northern District of California approved an amended settlement agreement ordering NOAA to submit a proposal regarding the 82 coral species on or before December 1, 2012. All of these coral species being proposed for listing are already protected under the Convention on International Trade in Endangered Species.

NOAA used the best available scientific information to assess the status of the species and decide if the species met the ESA’s definitions of endangered or threatened. Earlier this year, after publication of a peer-reviewed status review report and a draft management report, NOAA took an additional step of seeking public comment prior to proposing the listing. NOAA received approximately 42,000 comments and collected 400 relevant scientific articles, reports, or presentations, which were all considered when making the proposed determination.

NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Visit us at www.noaa.gov and join us on Facebook, Twitter and our other social media channels.

Gateway pipeline faces endangered species legal action

Several environmental groups are heading to federal court in an attempt to use the Species At Risk Act to block the construction of the Northern Gateway Pipeline.

Wilderness Committee policy director Gwen Barlee says the planned pipeline and shipping route would jeopardize Pacific humpback whales, Nechako white sturgeon, marbled murrelets and southern mountain caribou.

“So we’re just asking the federal government to do the right thing and fully implement the species at risk legislation that is supposed to protect these species,” said Barlee.

The legal action is being handled by EcoJustice on behalf of the David Suzuki Foundation, Greenpeace Canada, Sierra Club B.C., Wilderness Committee and Wildsight.  Read more
