I'm not a denier, but he has a fair point about the graph. The earth is 4.5 billion years old. Why look at only the temperature variation over the last 22,000 years?
Habitability. The earth can survive these temperature fluctuations, no question. Humanity has never lived through such a rapid change, or been on the other end of it where the higher temperatures are the norm. What happens if non-man made drivers start kicking in and amplifying temperature increase? How do we handle the migration of the 100+ million people who will need to migrate from island nations and major coastal citites in the next 100 years? What about our ports?
This article is helpful reflections on this topic:
Lastly, James Hansen just released his latest paper which is under peer review as a discussion document. I find it particularly useful becuase it talks about potential solutions, and criticizes what governments are "doing" to address the challenge. The video is worth watching as well:
Not sure if fata, but this is not going to be popular among Albertans, whom already dislike DiCaprio...

First, that graph is Antarctic, not global. And yes, I know the global doesn't look good either. And second, I can't believe I'm going to agree with Erick, but he's right. Notley's CO2 tax is idiotic. At bare minimum, all she had to do was look next door to BC to see that their implementation is better.

Don't worry Fuzz. If I had a dollar for every time someone said that I wouldn't be in freezing Alberta today. Everyone comes around sooner or later.
I also dislike that graph and the others in the newspaper article I saw it in as they aren't 0 based vertical indices, that can give the wrong impression sometimes and is a very common tactic of global warming deniers.
That said this year is pretty extreme for polar ice.

This past November was the warmest in the modern record and global sea ice has fallen off a cliff this year.
Spoiler!
It's probably nothing though and we should resume our complaints about Notley and her idiotic carbon tax idea.
So, aside from this year which seems to anomalous, the Antarctic sea extent has been steadily getting larger since 1978? Genuine question as that seems counter intuitive.
It has, it does seem at odds as the actual temperatures of the area have been increasing. The increased sea ice they think is partially due to the hole in the ozone layer decreasing, changing the temperature of the atmosphere and changing wind patterns and flow, pushing sea ice around more causing open areas and more of it to form.
Also warmer temperatures mean more moisture in the atmosphere, so more snow and rain, which makes the cooler surface water less dense so it mixes less with the lower warmer water, resulting in less ice melting. This may also be contributed to by the accelerating melting of antarctic land ice.
From what I remember they aren't that concerned about antarctic sea ice going up or down.

And I believe that most of the Antarctic ice cap is on land which doesn't heat up as much, while the ocean warming in the arctic is likely to have a bigger impact. Just a guess.
