Climate Connections: Questions from North and South Carolina
-
America has questions about climate change, and the USGS has real answers. In this episode of Climate Connections, USGS scientists answer questions gathered from North and South Carolina.

Climate Effects and Adaption in Forests
-
Dr. Christopher J. Fettig, Dr. Maria K. Janowiak, and Dr. Jessica E. Halofsky discuss how climate change driven increases in temperature and variation in precipitation are impacting U.S. forests and the wide range of ecosystem services they provide, sharing opportunities to proactively address risks to forests, and providing concrete examples of adaptation strategies and tactics that can be leveraged by the federal government and private landowners.

Climate Effects on U.S. Agriculture and Forests
-
Climate change effects are already evident in U.S. forests and agroecosystems. We are on the cusp of additional and potentially more severe effects, primarily facilitated by increased frequency and magnitude of extreme weather events (drought, heavy rainfall, heat waves) and associated disturbances (wildfires, insect outbreaks).

Climate Extremes in Agriculture and Forests
-
Atmospheric CO2 in the atmosphere is now likely higher than at any point in the last two million years. The effects of elevated atmospheric CO2 are interconnected, leading to changes in extremes in both weather and climate. USGS's Dr. Adam Terando discusses the consequences of changes in temperature, precipitation and drought to U.S. agriculture and forests, and approaches to adaptation.

Climate Impacts on Bird and Plant Communities From Altered Animal – Plant Interactions
-
The contribution of climate change to declining populations of organisms remains a question of outstanding concern. Much attention to declining populations has focused on how changing climate drives phenological mismatches between animals and their food. Effects of climate on plant communities may provide an alternative, but particularly powerful, influence on animal populations because plants provide their habitats. Here, we show that abundances of deciduous trees and associated songbirds have declined with decreasing snowfall over 22 years of study in Montane, Arizona, USA.

Climate Mapping for Resilience and Adaptation (CMRA) Portal
-
The Climate Mapping for Resilience and Adaptation (CMRA) portal, an easily accessible and interactive geospatial website, will help federal, state, local and tribal governments as well as non-profit organizations learn about climate hazards impacting their communities.

Climate negotiations under scientific uncertainty
-
How does uncertainty about “dangerous” climate change affect the prospects for international cooperation? Climate negotiations usually are depicted as a prisoners’ dilemma game; collectively, countries are better off reducing their emissions, but self-interest impels them to keep on emitting. We provide experimental evidence, grounded in an analytical framework, showing that the fear of crossing a dangerous threshold can turn climate negotiations into a coordination game, making collective action to avoid a dangerous threshold virtually assured. These results are robust to uncertainty about the impact of crossing a threshold, but uncertainty about the location of the threshold turns the game back into a prisoners’ dilemma, causing cooperation to collapse. Our research explains the paradox of why countries would agree to a collective goal, aimed at reducing the risk of catastrophe, but act as if they were blind to this risk.

Climate Outlook Looking Much The Same, or Even Worse
-
Climate scientists have been feverishly preparing analyses for inclusion in the fifth climate assessment report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) due out in 2013. At the meeting, they gave colleagues a peek at where climate science stands 5 years after their last push to inform the authoritative international evaluation . The climate models are bigger and more sophisticated
than ever, speakers reported, but they are yielding the same wide range of possible warming and precipitation changes as they did 5 years ago. But when polled on other areas of concern, researchers say they see more trouble ahead than the previous IPCC assessment had, though less than some scientists had feared
