On August 1, 2016, after nearly six years and two drafts, the White House Council on Environmental Quality (CEQ) issued a final version of its guidance for considering greenhouse gas (GHG) emissions and the effects of climate change under the National Environmental Policy Act (NEPA) (Final Guidance). CEQ previously released its initial draft guidance in February 2010 and a revised draft guidance in December 2014.
Like the previous drafts, the Final Guidance primarily reinforces the fundamental tenets of NEPA as applied to climate change. It offers little practical advice in attributing climate change effects to a particular federal action, and validates the broad discretion of individual federal agencies to tailor their NEPA reviews as they see fit. By its own admission, the Final Guidance is not a rule or a regulation, and the recommendations “may not apply to a particular situation.” Nevertheless, several important lessons become evident in the most recent changes.

Experts say human impact on Earth so profound that Holocene must give way to epoch defined by nuclear tests, plastic pollution and domesticated chicken.

NE CSC’s Research Ecologist Toni Lyn Morelli and colleagues have a new paper describing how scientists and natural resource managers are working together to understand how safe havens from climate change might be identified and conserved to protect species and cultural traditions.

Lamar Smith (R-Texas), chair of the House Science Committee, has used his position to demand emails and documents from state attorneys general and environmental NGOs as a response to their investigation of ExxonMobil. New York Attorney General Eric Schneiderman and the Union of Concerned Scientists are amongst the parties involved. They allege ExxonMobil suppressed climate change science, researched by the company’s own staff scientists over 30 years ago and Rep Smith has requested email logs from the accusers.
NGOs including 350.org and Greenpeace have pushed back, claiming that Smith’s subpoenas amount to federal overreach and have an ulterior agenda of interfering with their researchers’ work. In the latest twist of events, 350.org’s outside counsel requested a meeting with the Science Committee last month to discuss the subpoena and issues related to climate change science. According to 350.org, however, the request to meet Smith and the committee has been denied.

A new study from University of Michigan researchers challenges the widely held assumption that biofuels such as ethanol and biodiesel are inherently carbon neutral.
Contrary to popular belief, the heat-trapping carbon dioxide gas emitted when biofuels are burned is not fully balanced by the CO2 uptake that occurs as the plants grow, according to a study by research professor John DeCicco and co-authors at the U-M Energy Institute.

A new paper is challenging our understanding of how long human-caused climate change has been at work on Earth. And the authors say their findings may question existing ideas about how sensitive the planet is to greenhouse gas emissions — with potentially big implications for our global climate policy.
The new study, just out on Wednesday in the journal Nature, suggests human-caused, or anthropogenic, climate change has been going on for decades longer than existing temperature records indicate. Using paleoclimate records from the past 500 years, the researchers show that sustained warming began to occur in both the tropical oceans and the Northern Hemisphere land masses as far back as the 1830s — and they’re saying industrial-era greenhouse gas emissions were the cause, even back then.
