Officials say at least four people were killed (and 50 more injured) in that enormous gas line explosion in San Bruno, Calif. last night. Looking at the pictures from that night, it's amazing these numbers weren't a lot worse.

60 mph wind gusts are pushing the Colorado wildfire closer to the town of Boulder, and authorities have told residents that the western part of town may be evacuated. At least 170 homes have been destroyed this week.

An enormous explosion just rocked San Bruno, California, a suburb just above San Francisco International Airport. Like, really big: A whole block is on fire with 200-foot flames. Six people are in critical condition. What the hell is going on?

The wildfire in Colorado has claimed 135 homes, making it the most destructive in the state's history.

Along with Colorado, Detroit is now on fire too. At least two dozen homes have been lost to raging fires.

There was a three-alarm fire yesterday on a pier that housed Sanitation Department trailers, snow plows and employees' gear: "I lost everything, and I just did my laundry, too," one sanitation worker told the Times. Over 100 firefighters responded.

Russia is finally catching a break with some cool weather, and the fires are dwindling.

The devastating floods in Pakistan and widespread fires in Russia are caused by the same thing: God. Ha, no, totally kidding—they were caused by a "kink" in the jet stream, a "river of air" miles above the surface.

Some of the hundreds of wildfires that have burned western Russia have been reported in areas that were heavily contaminated by fallout from the 1986 Chernobyl nuclear disaster. Experts fear that smoke from fires in the area has become radioactive.

Russian Prime Minister Vladimir Putin put out two wildfires with his own bare hands. No, actually, he used a firefighting plane. That he built himself. No, actually, he didn't build it. He fathered it by having sex with a jet.

A fourteen-year-old who dropped a lighter while smoking weed was arrested for starting a 40-acre brush fire in L.A. county.

What happened this weekend? Major flooding killed hundreds in Asia and displaced thousands in Europe, while Russia battled back against peat fires blanketing Moscow in smog. Here, check out some of the breathtaking pictures.

Southern Russia is basically on fire. Yesterday alone, hundreds of fires broke out due to record heat and dry fields, and at least 28 people have died. But that didn't stop a few guys from driving through Hell on Earth.
