USGCRP Selects Scenarios for Next National Climate Assessment

USGCRP has selected a set of emissions scenarios and climate projections to focus on for the next quadrennial National Climate Assessment. These scenarios and projections will provide a consistent basis to assess the potential future impacts of climate change and related policy choices.

From Thawing Permafrost, Slow but Steady Emissions Likely

Thawing permafrost releases greenhouse gases into the atmosphere
A new synthesis published in Nature suggests that thawing Arctic permafrost will release greenhouse gases gradually, rather than in a sudden "bomb". The gradual rate of these natural emissions may give society more time to adapt to their effects, but they remain a challenge for climate mitigation .

IPCC Confirms: Climate Change is an Urgent Threat, Solutions Exist

A coastal wind farm
The Intergovernmental Panel on Climate Change (IPCC) released its Synthesis Report on Sunday, confirming that warming in the climate system is unequivocal and, if left unaddressed, will increase the likelihood of pervasive, irreversible damage to the environment and society. However, options to limit climate change and adapt to its impacts are available.

Federal Agencies Detail Their Risks From, Responses to Climate Change

Flooding from an extreme rainfall event damaged infrastructure at DOD’s Fort Irwin in 2013.
On Friday, Federal agencies released their annual plans for reducing their greenhouse gas emissions and preparing for the impacts of climate change . Agencies cited climate impacts like rising sea levels, increased storm intensity, and more extreme temperatures as threats to Federal facilities, operations, and resources.

New NASA research shows that Earth's atmosphere contains an unexpectedly large amount of carbon tetrachloride (CC14), an ozone -depleting chemical that was banned worldwide decades ago. According to the study, global emissions of CCl4 average 39 kilotons per year—approximately 30 percent of peak emissions prior to its banning.

IPCC: Many Pathways to Reduce Climate Change

IPCC report on climate change mitigation has implications for energy use
The latest report by the Intergovernmental Panel on Climate Change (IPCC) shows that global emissions of greenhouse gases have risen to unprecedented levels, despite a growing number of policies to reduce climate change. Nevertheless, a wide array of technological measures and behavioral changes could limit the increase in global mean temperature to two degrees Celsius above pre-industrial levels.
