Intense Downpours More Common

摘要

A report on extreme weather warns that human-induced climate change is making heavy downpours more intense, with storms that used to occur every 20 years projected to occur every 8 years by the end of the century. "As greenhouse gases increase, the faster they increase, the more extreme weather and climate events we'll be seeing," said Thomas Karl, co-editor of the report and director of the National Climatic Data Center at the US National Oceanic and Atmospheric Administration.
