Global warming: are you under water?

this epic news was reported in japan in approx 1 month after english medias reported it.

Scientists just accidentally discovered a process that turns CO2 directly into ethanol

Rocks falling into oceans, not climate, causing seas to rise, congressman suggests

A rolling stone may gather no moss, but if it tumbles into the ocean, you can expect the seas to rise.

At least that's the theory embraced by Rep. Mo Brooks, R-Ala., during a hearing held Wednesday by the House Committee on Science, Space, and Technology on how technology can be used to address climate change.

While questioning Philip Duffy, president of Woods Hole Research Center, about what, in addition to climate change, might be driving rising sea levels, Brooks suggested erosion might be a factor.

"Every single year that we’re on Earth, you have huge tons of silt deposited by the Mississippi River, by the Amazon River, by the Nile, by every major river system — and for that matter, creek, all the way down to the smallest systems," Brooks said. "And every time you have that soil or rock whatever it is that is deposited into the seas, that forces the sea levels to rise. Because now you’ve got less space in those oceans because the bottom is moving up."

Brooks pointed to the White Cliffs of Dover and to California "where you have the waves crashing against the shorelines" and "you have the cliffs crash into the sea."

"All of that displaces the water which forces it to rise, does it not?" Brooks asked.

[...]

There you have it.

Personally I blame the whales, Japan is actually saving us from inundation.

Small Nuclear War Could Reverse Global Warming for Years

Even a regional nuclear war could spark "unprecedented" global cooling and reduce rainfall for years, according to U.S. government computer models.

Widespread famine and disease would likely follow, experts speculate.

During the Cold War a nuclear exchange between superpowers—such as the one feared for years between the United States and the former Soviet Union—was predicted to cause a "nuclear winter."

In that scenario hundreds of nuclear explosions spark huge fires, whose smoke, dust, and ash blot out the sun for weeks amid a backdrop of dangerous radiation levels. Much of humanity eventually dies of starvation and disease.

Today, with the United States the only standing superpower, nuclear winter is little more than a nightmare. But nuclear war remains a very real threat—for instance, between developing-world nuclear powers, such as India and Pakistan.

To see what climate effects such a regional nuclear conflict might have, scientists from NASA and other institutions modeled a war involving a hundred Hiroshima-level bombs, each packing the equivalent of 15,000 tons of TNT—just 0.03 percent of the world's current nuclear arsenal. (See a National Geographic magazine feature on weapons of mass destruction.)

The researchers predicted the resulting fires would kick up roughly five million metric tons of black carbon into the upper part of the troposphere, the lowest layer of the Earth's atmosphere.

In NASA climate models, this carbon then absorbed solar heat and, like a hot-air balloon, quickly lofted even higher, where the soot would take much longer to clear from the sky.

Reversing Global Warming?

The global cooling caused by these high carbon clouds wouldn't be as catastrophic as a superpower-versus-superpower nuclear winter, but "the effects would still be regarded as leading to unprecedented climate change," research physical scientist Luke Oman said during a press briefing Friday at a meeting of the American Association for the Advancement of Science in Washington, D.C.

Earth is currently in a long-term warming trend. After a regional nuclear war, though, average global temperatures would drop by 2.25 degrees F (1.25 degrees C) for two to three years afterward, the models suggest.

At the extreme, the tropics, Europe, Asia, and Alaska would cool by 5.4 to 7.2 degrees F (3 to 4 degrees C), according to the models. Parts of the Arctic and Antarctic would actually warm a bit, due to shifted wind and ocean-circulation patterns, the researchers said.

After ten years, average global temperatures would still be 0.9 degree F (0.5 degree C) lower than before the nuclear war, the models predict.

Years Without Summer

For a time Earth would likely be a colder, hungrier planet.

Maybe with a big nuclear war, we could have even more snow, I so want snow!

Nah, you'll be so hungry that you'll even eat yellow snow...
