Abstract
Global warming over the past several decades is now large enough that
regional climate change is emerging above the noise of natural
variability, especially in the summer at middle latitudes and year-
round at low latitudes. Despite the small magnitude of warming relative
to weather fluctuations, effects of the warming already have notable
social and economic impacts. Global warming of 2°C relative to
preindustrial would shift the ‘bell curve’ defining temperature
anomalies a factor of three larger than observed changes since the
middle of the 20th century, with highly deleterious consequences. There
is striking incongruity between the global distribution of nations
principally responsible for fossil fuel CO2 emissions, known to be the
main cause of climate change, and the regions suffering the greatest
consequences from the warming, a fact with substantial implications for
global energy and climate policies.
