You might have heard from the climate change deniers that this year will be the coolest globally this century. And that is true.

Newly released data from the UK Met Office shows that during the first half of 2008 the global temperatures was more than 0.1 Celcius cooler than any other year after 2000. The reason for this is La Nina, an ocean-atmosphere phenomenon that has a cooling effect on the earth.

But this doesn’t mean the deniers are correct about anything else. Scientists still expects that 2008 will be the 10th warmest year since 1850. And the UK Met Office says that the global temperatures will continue to rise again when La Nina eases away.

Last week the ice at the North Pole melted at an “unprecedented rate.” And that has some scientists worrying that the Arctic could become ice-free during the summers as early as 2013, the Guardian reports.

The storms over the Alaska’s Beaufort Sea last week brought with them not just bad weather but also streams of hot air into the Arctic. Satellite images that were taken shortly after could show that the ice caps had started to “disintegrate dramatically.” And because of that the scientists believes that the melting could exceed last year’s record loss of ice.
