2014 set a new mark for the hottest year on record. And while unprecedented heat has become almost common place, it's been a long time since the world set any global cold records.
Thanks to NASA, you only need 30 seconds to see how the world has warmed over the past 135 years.
Climate Central Chief Climatologist Dr. Heidi Cullen explains in a panel discussion on ABC’s This Week with George Stephanopoulos how climate change increases the risks of extreme weather events like heat waves, droughts, and monster storms.
Updated to include 2013, this amazing 14-second NASA animation depicts how the globe has warmed since 1950.
In our Extreme Weather 101 video, scientists explain how heat spikes are likely to become more common.
The year 2012 has become the hottest year in the U.S. since scientists began keeping records. As Climate Central Chief Climatologist Dr. Heidi Cullen tells ABC’s Dan Harris on World News Tonight with Diane Sawyer, don’t expect this record to be the last.
This NOAA animation shows the locations of each of the 7,793 daytime and 7,493 nighttime records (or tied records) in sequence over the 31 days in March.
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.
