Greenland ice core hints at Earth's next big melt

An international team of scientists has drilled down through 2.5 kilometres of Greenland ice and uncovered a surprising picture of Earth's last big melt — along with predictions about the one taking place right now.

Clearly another CYA moment and a logical explination as to why Big Al would buy beach front property.

On one hand, that's good news, as Greenland has undergone alarmingly rapid warming in recent years. According to the NEEM scientists, Greenland's average temperature has been rising five times faster than the global average, but the new results suggest the impact on the oceans may not be as dramatic as others have predicted.

I don't find that terribly frightening.

The collaboration discovered that during the Eemian period, Greenland was about 8 C warmer than it has been for the past 1,000 years. That's about 6 degrees warmer than climate models had predicted, said lead author Dorthe Dahl-Jensen of the University of Copenhagen.

At the same time, the data also showed that only 25 per cent of the volume of the ice sheet melted, which suggests that the melt didn't contribute as much as expected to the rise in global sea levels, which was four to eight metres higher than they are today.

Models - the things they use to Nostradamus a coming, human caused catastrophe were once more shown to be incorrect by the data.

Once more we see it's been much warmer than it is today, and life thrived. They talk about the Eemian period (130,000 to 116,000 years ago)

The Hippopotamus was distributed as far north as the rivers Rhine and Thames.

And they say even if there is a similar Greenland melt it won't be as hard on sea level rise as as alarmists once tried to scare us by expecting.

My opinion on the matter of climate change has gotten muddy. I'm against pollution, and feel the responsibility for that lies more on corporations who waste vast amount of water, resources, and energy while encouraging consumers to "cut down". Whether or not the temperature is rising due to human intervention doesn't detract from my desire to breathe clearner air.

That said, I've always been amused by the debate:

One side seems to present numbers and information like a motherfucker, while the other side counters by just saying "It's cold."

Like I stated though, I don't subscribe. I am strongly in favour of anti-pollution and anti-waste policies being put in place to restrict the ability of capitalist institutions to rape our planet. Whether or not the loss of trees in Brazil means the temperature will rise doesn't change my opinion that we shouldn't be cutting down all the fucking trees.
