Sometimes I really wonder why so many people who can't spell think that they are so much smarter than 'those scientists'.

[satchel40]

Personally, I'd rather play it safe. The stakes are just too high. Also, if we're wrong, it just means we have a cleaner planet. Isn't that good?

nice fear timelaps video there it goes from the end of winter to the middle part of summer...of course the ice is going to retreat

[murph1329]

he said it was the first time they've been able to see the average depth of the ice yet then he says it's smaller than it's ever been???? what the hell if it's the first time you've been able to average it what do you have to compare it to?

stupid nasa empoyee is stupid

If million cubic meters of ice have melted & the ice sheet retreated to record lows, where did the melted ice went? If it melted to water, it would raised the water level considerably, flooding the neighboring shorelines. The ice was NOT replaced by any rise in sea level locally or the sea levels all over the world. Could the ice also sublimated and the heated water (w/o ice cover) evaporated in the atmosphere? Dropping it as rain, hale & snow like the current weird weather we have all over.

CC was nuclear lies

@Libertarianist They can't explain the recent warming without including man-made co2 pollution in the greenhouse.

[cypress1337]

@GoneBad666 Only 2% of the scientists disagrees (which are funded by multinational oil company's to look like 98%).

And making clean energy isn't so bad i think. Energy based on co2 pollution ís bad in my opinion.

@voic3z Maybe, your the man who can make a mirror as big as the Artic ice sheet and install it then. Smart-ass.

[voic3z]

functions like a giant mirror you say? i know something else that functions like a giant mirror...a giant mirror.

I dont see how i can belive in the AGW theory without any doubt when not all scientists agree with it.

I do not consider myself smarter than ANY scientist, therefore my view in the matter is only making things worse. A theory can only be proven by future evidence in nature, and without that, AGW theory is not proven. We do not have all the warming variables, without them we can never be 100% sure what will happen in the future.

I'll concede the Chinese North pole story. To be honest I had heard about it in a video rebutting GW alarmism, but not bothered to verify it.

One thing that is true, however is the existence of viking farms in Greenland that are now covered in permafrost and ice. The medieval warm period DID exist and the temperature was even warmer than today.
