Adapting to Climate Change in Europe and Central Asia

Description: Contrary to popular perception, ECA faces significant threats from climate change, with a number of the most serious risks already in evidence. Vulnerability over the next ten to twenty years will be dominated by socio‐economic factors and legacy issues. Even countries and sectors that stand to benefit from climate change are poorly positioned to do so. The next decade offers a window of opportunity for ECA countries to make their development more resilient to climate change while reaping numer… more

Thresholds of Climate Change in Ecosystems

Description: This Report (SAP 4.2) focuses on the thresholds of Climate Change in Ecosystems. As defined in this Synthesis and Assessment Report, 'an ecological threshold is the point at which there is an abrupt change in an ecosystem quality, property, or phenomenon, or where small changes in one or more external conditions produce large and persistent responses in an ecosystem'.Ecological thresholds occur when external factors, positive feedbacks, or nonlinear instabilities in a system cause changes to pr… more

Climate Projections Based on Emissions Scenarios for Long-Lived and Short-Lived Radiatively Active Gases and Aerosols

Description: This report focuses on the Climate Projections Based on Emissions Scenarios. The influence of greenhouse gases and particle pollution on our present and future climate has been widely examined. While both long-lived (e.g., carbon dioxide) and short-lived (e.g., soot) gases and particles affect the climate, other projections of future climate, such as the IPCC reports focus largely on the long-lived gases. This U.S. Climate Change Science Program Synthesis and Assessment Product provides a diffe… more
