There is a problem here....with a environmental guy who has no knowledge of cause and effect.
Once you get a fairly substantial amount of the ice to melt...it flows down off the side of Canada (east and west), and gets into the Atlantic and Pacific streams. This radically changes weather. The reason we know? It’s done it before. All of this will eventually bring about cooler temps which mean an eventual heavy snowfall in the north circles, and more creation of ice.
The thing about climate change....it’s eternal. You can’t stop it. To pretend that it’s all stable....is the fallacy of this whole mess.
There is currently no substantial ice melt, nor has there been for 10,000 years. There are minor fluctuations in land ice with the start and recent end of the Little Ice Age, but those fluctuations do not affect the weather. More likely the opposite is true, it is the weather patterns, driven by solar factors, that result in the changes in climate.
