Sharp rise in Arctic temperatures now inevitable – UN

We always hear about tipping points being triggered when there is no evidence that these tipping points exists.
Consider Greenland's ice core temperatures.

Notice that past Greenland temperatures exceeded even the GISP temperatures by over 1C above current levels, and yet not tipping point was tripped.
I think Greenland counts as the Arctic.

Did you see that little blue cross on the top right? Where do you think the 2016 mark would be?

Really? The very definition of a "tripping point" means that it hasn't happened yet. Once it happens, there is no tripping backwards. I won't make my usual statement that tens of thousands scientists are backing the "tripping point" outlook, but I'd be willing to bet that most of them think that the probability is greater.

"Tipping point" was intended, I believe.

If a tipping point, (An irreversible trigger event) existed, it would have been tripped long ago.
And I do not think you can find any documented support by tens of thousands scientists that said tipping points exist with regards to the climate.

Nothing to back up that whopper...
 
Except the evidence that he provided showing that it has been lots warmer in Greenland since the last ice age without any tipping point.

Like I said, nothing to back up that whopper. We don't know the circumstances of the earth that caused the readings, and we don't know the effects of that on the life of the planet.

Eh????????????????

We know that the ice/snow contains the record of what temperature it was when it fell. This is how the graph was constructed. Unless you want to get into denying science.....

So the idea that a rise in temperature around Greenland will not cause it to collapse. This utterly plain.

Consider the GISP2 noted on the other graph.

Even if we raise the line up the GISS's 64N to 90N zone, difference since 1950,
there are still several peaks that exceed today's temperatures by quite a bit,
yet strangely, no tipping point observed.

Ice Cores May Not Be Accurate Thermometers - Astrobiology Magazine

The researchers zeroed in on the Northern Hemisphere’s temperature outlier, Greenland ice cores, and found that the conversion of oxygen isotope ratio to temperature typically used on the ice cores did not account for the sort of crash climate change occurring during the Younger Dryas. It assumes prevailing winds and jet streams and storm tracks are providing the moisture for Greenland precipitation from the Atlantic Ocean.

They may or may not be good indicators of global temperatures but when the temperature record from the residual tiny temperature variations is used they are very good indicators of local temperatures.

I don't know which is used here but I do know that the temperature based ones show warmer times in the past.

I don't know what you are trying to say...

It is not hard:

You claim that there is a dangerous tipping point about to happen due to the temperature of Greenland rising.

Longview says that there have been warmer temperatures in the past. He cites evidence to support this. If there have been it means that those temperatures did not cause anything drastic to happen so they won't do so this time.

No, he doesn't. The current temperature of Greenland is higher than at any time since the last interglacial period.
 
Norwegians. What do they know about the arctic. Amirite?

So what are you doing for the next 11 years?

"OCASIO-CORTEZ: “And I think the part of it that is generational is that millennials and people, in gen z, and all these folks that come after us are looking up and we’re like, the world is gonna end in 12 years if we don’t address climate change. You’re biggest issue, your biggest issue is how are going to pay for it? — and like this is the war, this is our world war II. And I think for younger people looking at this are more like, how are we saying let’s take it easy when 3000 Americans died last year, how are we saying let’s take it easy when the end person died from our cruel and unjust criminal justice system? How are we saying take it easy, the America that we’re living in today is dystopian with people sleeping in their cars so they can work a second job without healthcare and we’re told to settle down. It’s a fundamental separation between that fierce urgency of now, the why we can’t wait that King spoke of. That at some point this chronic reality do reach a breaking point and I think for our generation it reached that, I wished I didn’t have to be doing every post, but sometimes I just feel like people aren’t being held accountable. Until, we start pitching in and holding people accountable, I’m just gonna let them have it.”"

I hope she has a plan B if she lives longer than that.

That chick makes A LOT of sense!

Tell us... where are today’s temperatures on that graph?

The GISP2 ice core dataset ended in 1855.

How many times does this bunch of fake "skeptics" need to be told that? You'd think a real skeptic would have found that out for themselves.
