The US has entered the 34th day of a crippling heat wave, with no sign of relief in sight. According to the National Climatic Data Center (NCDC), July's broiling temperatures affected close to 200 million Americans, and set 2,755 daily-high records across the country — including at least one record in every state.

The map above is from NASA's Earth Observatory, and depicts something called "land surface temperature anomalies" from July 20-27, when the heat wave reached its peak intensity across much of the United States.

The map works a little differently than your typical heat map; instead of depicting absolute temperatures, the image uses color-mapping to illustrate the difference between average temperatures for the week of July 20th and the long-term average temperatures for regions across the US. So this map is showing you how unusual the temperatures were across the country.

For a better idea of how the heat wave evolved over the course of July, check out the lime-lapse videos depicting temperature anomalies for daytime and nighttime surface air temperatures.

CURSE YOU TIME MAGAZINE! WHAT THE HELL AM I SUPPOSED TO DO WITH ALL THESE PARKAS AND SNOW SHOVELS?

30 years ago the world was turning to ice, and now the its literally melting like the wicked witch of the west. Do we really have to wait 30 years to know what is actually going to happen. A little more transparency from the scientific community would be nice. Stop hoarding information like its trade secrets.

Scientist today need to look to Jonas Salk's example when looking for guidance. He gave away the polio vaccine. He saved millions of lives. Science isn't about making money. Its about advancing civilization.

"There is no patent. Could you patent the sun?" (Jonas Salk)
