The new scenario implies a grim future for billions of people around the globe, with even more damaging impacts than have so far been expected in terms of droughts, extreme weather events such as hurricanes, rainstorms and flooding, and sea-level rise. Global warming may boost world temperatures by up to 11 degrees Fahrenheit by the end of the 21st century, a figure substantially higher than previous estimates,according to a group of climate scientists sponsored by the United Nations. Scientists working on an ice core taken several miles beneath the surface found the first evidence of rapid warming in the Antarctic. It suggests a temperature spike of around four degrees Celsius took place in the south pole region over about a decade 19,000 years ago. Heavy Climate Impacts Forecast for Southern Europe Northern Europe and Britain can expect more flooding and torrential rains in the years to come but southern Europe will bear the brunt of the impact of global warming with water shortages, forest fires and desertification.
Natural sinks are unable to assimilate human-generated carbon dioxide.
WMO sees Climate Change Driving Asian Floods, Droughts Heavy rains and flooding in southern parts of Asia this year coupled with drought across swathes of Central Asia may be a sign of more profound climate change, according to a top U.N. weather expert. As the global climate changes, extreme weather events such as droughts, floods, heat waves, heavy rainfall, tropical storms and hurricanes are expected to increase. At the same time, extreme weather events have had increasing impact on human health, welfare, and financial losses. This trend is likely to become more intense in the years to come. Near-Term Warming Forecasts of climate change are inevitably uncertain.
