According to a new report from the National Oceanic and
Atmospheric Administration (NOAA), climate change may
play a role in extreme weather.
The report said 2011 was the coolest year since 2008. But it
was still one of the 15 warmest years since records began in
the late 1800s. Among the extreme weather events, scientists
looked at a record heat wave in Texas. Last year, Texas
had the driest seven-month drought ever recorded. NOAA
found that the Texas heat wave was 20 times more likely to
occur today than 50 years ago.
At the end of June, more than 110 million people were living
under extreme heat and more than two-thirds of the USA
was experiencing drought.
