Like Never Before: That spike everyone has talked about

A new study looking at 11,000 years of climate temperatures shows the world in the middle of a dramatic U-turn, lurching from near-record cooling to a heat spike.

Research released Thursday in the journal Science uses fossils of tiny marine organisms to reconstruct global temperatures back to the end of the last ice age. It shows how the globe for several thousands of years was cooling until an unprecedented reversal in the 20th century.

Scientists say it is further evidence that modern-day global warming isn’t natural, but the result of rising carbon dioxide emissions that have rapidly grown since the Industrial Revolution began roughly 250 years ago.

The decade of 1900 to 1910 was one of the coolest in the past 11,300 years — cooler than 95 percent of the other years, the marine fossil data suggest. Yet 100 years later, the decade of 2000 to 2010 was one of the warmest, said study lead author Shaun Marcott of Oregon State University. Global thermometer records only go back to 1880, and those show the last decade was the hottest for this more recent time period.

“In 100 years, we’ve gone from the cold end of the spectrum to the warm end of the spectrum,” Marcott said. “We’ve never seen something this rapid. Even in the ice age the global temperature never changed this quickly.”

Lava on Ice, and other Lava Pourings

Geology typically requires a suspension of our everyday sense of time to be appreciated. If you stare at a rock for a minute or two, you’re unlikely to be rewarded with much action—unless you throw it. But that doesn’t do it for everybody.

What does do it for just about everybody is volcanoes. Big, violent volcanoes. Angry mountains spewing their molten guts high into the atmosphere, with fiery blobs and bits flying everywhere. Of course, such sights are preferably taken in through the comforting insulation of a television set—even a relatively calm volcano like Hawaii’s Kilauea demands serious precaution.

Finnish Fishing Under Ice

Feel free to mute the video above and use the alternative soundtrack below by
JAMES McDOUGALL from his release on Impulsive Habitat.

Fishing under ice begins with a diver appearing to walk on the frozen floor of lake Saarijärvi in Vaala, Finland – but a few seconds later things strange things begin to happen.

Divers:
Fisherman: Eelis Rankka
Fisherman’s friend: Tommi Salminen
Boy with the balloon: Jukka Pelttari
