From the second (the first is purely about the technical measurements):
> „... Examination over a longer period (1980-2017) shows that the total amount of snow in all winter periods has decreased on average.
The ice cover on the Arctic Ocean has grown thinner and the amount and expanse of perennial ice has decreased. [...] Extreme weather phenomena including winters in which snowfall is quite heavy, and periods of little snow, will increase in the future.
The Arctic area is warming at twice the speed as the rest of the world, and the impact of climate change can already be seen in the Arctic regions. And the changes are affecting the rest of the Earth.
- chrisco255 7y agoI guess you didn't hear about the little ice age scare in the 70s? Take Leonard Nimoy's word for it: https://youtu.be/mOC7ePWCHGk https://youtu.be/mOC7ePWCHGk hard to argue with Spock. It's not surprising that ice loss occurred over the last few decades. Is this unprecedented in geological history? Not at all. The medieval warm period from 950-1250 was as warm as today if not warmer. It was followed by a little ice age that lasted 600 years, followed by the modern warming period which began in 1850, well before internal combustion engines took off. The loss or gain of ice in the Arctic occurs regularly. It's been happening in spurts since the end of the last glacial period 20,000 years ago. There are natural cycles like the Atlantic Multi-decadal Oscillation that have a huge influence on Arctic ice extent.
- pintxo 7y agoAccording to [1] we are already way beyond the temperatures of the medieval warm period. So not sure your argument holds. Also, apparently this effect was localized, not global. I guess there is no one disputing that Earth climate is driven by multiple sources, so that’s not the point. The question is: are we driving climate change to a large enough extend that we could have an impact on it by changing what we do? And the consensus seems to be a strong yes. The other question is: is climate change a net negative? And again the answer seems to be a strong yes.
