Warming is causing soil-based microorganisms to release carbon dioxide in a potentially catastrophic process that could add at least as much carbon to the atmosphere as the fossil fuel industry emitted in the mid-20th century, a study finds.
Lake sediments in a Siberian crater show that the last time atmospheric carbon dioxide was at present levels, global temperatures were 14.4 degrees hotter, forests covered the tundra and sea levels were up to 130 feet higher than they are today.
If the Earth's average global temperature rises by another few tenths of a degree, a large area of Siberian permafrost will start to melt uncontrollably, releasing 160 to 290 billion tonnes of carbon dioxide into the atmosphere in the years that follow. But the dangers have been overhyped, a British climate scientist says.
After a protest against the Russian government composed entirely of plush toys and figurines captured the attention of the press and local authorities in Barnaul, Russia, last month, government officials have gone so far as to specify that inanimate playthings can't assemble for public political gatherings.
It's getting crowded in space. A U.S. telecommunications satellite and a defunct Russian satellite smacked into each other in orbit over Siberia on Tuesday. According to NASA, no one was to blame for the unprecedented collision: "We don't have an air traffic controller in space."
Although Canada and the U.S., among other nations, are disputing Russia's claim to vast territory in the Arctic, Russia has planted its flag on the ocean floor at the North Pole. Why does it matter? Well, some 25 percent of the Earth's oil reserves might be at stake.
