How can global warming of less than 1 degree Celsius drive extreme weather?



c) Most of the heat from that increase is being stored by the oceans.

Answer: c) You might need to look beneath the surface (of the ocean) for the answer.

Heavy Precipitation. In recent years, a higher percentage of precipitation in the United States has come in the form of intense single-day events. Nationwide, eight of the top 10 years for extreme one-day precipitation events have occurred since 1990. The occurrence of abnormally high annual precipitation totals (as defined by the National Oceanic and Atmospheric Administration) has also increased.

Changes in many extreme weather and climate events have been observed since about 1950. Some of
these changes have been linked to human influences, including a decrease in cold temperature
extremes, an increase in warm temperature extremes, an increase in extreme high sea levels and an
increase in the number of heavy precipitation events in a number of regions. {ipcc, 1.4}
