Hot, hot, hot!

In hot water: World sets ocean temperature record

Breaking heat records in water is more ominous as a sign of global warming than breaking temperature marks on land, because water takes longer to heat up and does not cool off as easily as land.

"This warm water we're seeing doesn't just disappear next year; it'll be around for a long time," said climate scientist Andrew Weaver of the University of Victoria in British Columbia. It takes five times more energy to warm water than land.

The warmer water "affects weather on the land," Weaver said. "This is another yet really important indicator of the change that's occurring."

Global Warming Could Actually Tilt the Earth's Axis

Scientists have long theorized that climate change could cause a negligible amount of movement in the axis, but NASA;s research shows that the problem could be much more severe than was initially thought. In fact, it could be as drastic as the northern pole shifting by 1.5 centimeters every year towards Hawaii and Alaska.

Did they say drastic? 1.5 cm/year?
10 years -> 15cm
100 years -> 1,5m
1 000 000 years -> 15km
(hardly noticeable).
