As Dr. Heidi Cullen reports, the suffocating heat comes on the heels of the government's release of the new climate "normals". Every 10 years, scientists from the National Oceanic and Atmospheric Administration calculate the 30-year averages for temperature and precipitation from thousands of U.S. locations.
National Hurricane Center scientist Jack Beven explains the technology used to forecast and track hurricanes as they happen.
This year's Atlantic hurricane season is expected to be busier than usual and the 2011 summer forecast calls for some extreme weather. Heidi Cullen makes the climate connection.
With what feels like an especially long winter coming to an end, Dr. Heidi Cullen gives a climate outlook for spring 2011.

Dr. Heidi Cullen has a look behind the numbers of the just-released NOAA temperature analysis, and reports on the 2010 hurricane season as it passes the midway mark.
Take a look at the summer of 2010, with record breaking heat and severe weather.
Dr. Jack Beven explains his work at the National Hurricane Center, where he helps issue hurricane warnings that keep people out of harms way.
