No. If we're very lucky, we arrest the rise in temperature and Miami and the Maldives aren't submerged. Nothing in any of this looks like bringing temperatures back to where they were pre-1800.

If you have a glass of water with ice full to the brim does it overflow when the ice melts ? I thought water expanded when it turned to ice not the other way.

But ice can be stacked up in one place causing little harm but then wanders off elsewhere when it melts. Especially, since whilst the NP is on water, a lot of the ice around it and at the South Pole is on land.

I get the bit on land falling into the sea can cause a bit of a splash but given 75/80% of the planet is water would it really raise the level that much ? The North pole volume in the water, the weight offsets the amount of water as seen with the glass experiment.
How much more water is there to melt ? Given there used to be a whole land mass between NL and Norway (Doggerland) which is only a few metres beneath the North Sea and a fishing ground now - Doggerbank. Apparently the Isles of Scilly were connected to Cornwall once. How much ice sank all of that ?

I am no expert, so don't quote me.
But as I recall if floating ice were to melt then the amount of water added to the ocean is approximately 3% more than the volume of the water originally displaced, and so this would result in a 5 cm rise in seal level. However, that's just floating ice, land ice is the real and really big problem.
10% of the world's surface is covered by ice. 90% of that is in Antartica, 10% is in Greenland and the rest doesn't matter very much. The Greenland ice sheet is, obviously, on land and amounts to 3 million cubic metres of ice. If that melts then sea levels would rise by 7 metres.
If all of the land ice melted, then sea levels would rise by about 70 metres.
Your glass of water anology applies only to ice floating on water, approximately 0.1% of the problem, given that is is 0.1% of the world's ice.
I expect I've got some of the figures a bit wrong, it's been a while, but I assure you that my proportions are correct.
So put more ice in your G&T, we need to use the damn stuff up as quickly as possible before it has a chance to melt.

Perhaps worth pointing out that London is 10m above sea level, Paris about 35m, Glasgow 30 m and Edinburgh 45m so you can imagine the impending impact. Well, not so much from Glasgow drowning, but from the others.

As an after thought...
>>I thought water expanded when it turned to ice not the other way.
Don't forget when it is ice in a glass of fresh water only about 1% of it sticks above the water level. When it is an iceberg in salt water it is more like 10% above the surface, though some of that is that icebergs have more air in them than ice cubes.

Do you put ice in a pisco sour?
And will I find one in Panama?!

I'm no climate change denier what I would like to see (maybe this is more a reflection of my own reading than what is available) are the facts. All this 2 minutes to midnight, 30 seconds to midnight, 2 seconds to midnight guff doesn't do anyone any favours. You hit midnight and a new day begins, not really the end of days the media would like us to believe.
Some of the planet has benefit from fossil fuel the remainder have seen this and like the idea of mechanisation and being told by the industrialised world no, you should not do it, it is wrong while still addicted to fossil fuel.

…what I would like to see (maybe this is more a reflection of my own reading than what is available) are the facts. I’m not sure where you’re looking but there’s plenty out there. Try The Economist, which makes much of its content on major issues available FOC. Everything in the Guardian is free to read, and free from the corporate ownership that biases some other papers. And the dear old BBC’s Fact Check does a good job on this and other matters where obfuscation is a problem. All this 2 minutes to midnight, 30 seconds to midnight, 2 seconds to midnight guff doesn't do anyone any favours … You hit midnight and a new day begins. Tell that to Cinderella. 🤓

Ah well, Biden is releasing a million bpd from strategic oil reserves on to the market for the next 180 days... Crisis kicked down the road again? Fill ‘er up Humph!

Some of the planet has benefit from fossil fuel the remainder have seen this and like the idea of mechanisation and being told by the industrialised world no, you should not do it, it is wrong while still addicted to fossil fuel. [been writing this in between doing something else, haven't had a chance to read it back, hopefully it makes sense] The world is warming, the ice *will* melt, the Earth will cease to be inhabitable for all. We are absolutely in the business of kicking the can down the corridor, there is no other path. And really we'd like to kick it a very long way down the corridor so that we can not think about it. The can is sufficiently far down the corridor at the moment that everybody here will be dead before the sticky stuff hits the whirly thing hard enough to kills us. I don't really see how it can be doubted that our behaviour will make it worse (or quicker). It depends how far into the future you care about, I guess. For me, I like living in a responsible way, I try not to leave a trail of destruction behind me, and by and large I think the lifestyle represented as environmentally responsible is actually a way of life and behaviour that I support and like to live. Though that said, I am not obsessive about it - I fly, drive and sometimes use more electricity than I need etc. etc. Sometimes I think the argument over climate change is not dissimilar to that over vaccination. Those that do not believe in it seem to need to convince everybody else not to believe in it, and vice versa. For me, I don't feel the need to convince others, though obviously I am happy to discuss it. Mostly I just worry about waht I do.

Climate change and vaccination in the same post..?! There’s an argument waiting to happen! 😂. Throw in Brexit too?!

I wonder whether we’ll be actually solving the “climate crisis” once fuel soars above 2 quid a litre?! Everyone will a) be driving less and b) needing every penny to pay for escalating prices on food and pretty much anything else that requires shipping/trucking/delivery.
The Ukraine war is just a smoke screen I tell you! 😬🤨
