Yet another phenomenally intense rainfall event has occurred in the U.S. this morning (August 22nd) when 3.95” of rain in one hour was measured by a COOP observer at a site 3 miles southwest of Chicago’s Midway Airport. The return period for such at Midway Airport (according to NOAA’s ‘Precipitation Frequency Data Server’) is once in 500 years. This is similar to the Baltimore, Detroit, and Islip, New York events last week (although the Islip event was probably more in the range of once in a 1000 years).

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
