(Newser) – The heat wave currently plaguing the US has broken more than 1,000 heat records and claimed 13 lives, the BBC reports. Eighteen states from Montana to West Virginia are under a National Weather Service heat advisory, with temperatures reaching more than 90 degrees in many states and the heat index topping 100 degrees, and the high temperatures are moving east. In some regions, the heat index—a combination of temperature and humidity—reached as high as 131 degrees.

Roads are cracking and water mains are rupturing in Oklahoma, and the US Border Patrol says more illegal immigrants are dying as they try to cross the border under these dangerous conditions. The AP explains that the US is baking in a heat "dome," which is like a pressure cooker. The dome, created by a large high-pressure area, compresses hot, moist air underneath it, thus creating the miserable conditions. Click for more on the phenomenon.

Global warming is not science, it is a consensus of government employees looking for more taxpayer handouts (research grants) so they can continue their research jobs. You can't use global warming to explain everything that happens in weather. Massive precipitation, little precipitation, record heat, record cold, everything 'unusual' in weather patterns is now blamed on global warming. You could blame it on the hole in the ozone layer, space aliens, or heck, the sun cycles.

So where are all of the jackasses who call global warming a load of BS when the temperature is slightly below the seasonal average? Are 1000+ heat records enough evidence for you, or are you going to keep your fingers in your ears and wait until the temperature drops a few degrees to pretend you're a climate scientist again?

This is God's punishment on the Midwest for being brain-dead religious zealots. Even God can't stand them.
