If you are talking about change in last 100 years.....if that’s your question........I am not sure there has been a significant Climate shift in that time. I believe originally the calculation was that it might take 3,000 years or so for Caps to melt. However, now they say it might take only couple of hundred years at the current pace. So no, there is is nothing IMMEDIATE that is expected, either in our lifetime or next generation’s. The thing is that a problem as big as Climate Shift, you can’t fix it AFTER it begins or can you? You have to take precautions to best of our understanding what is causing the cap melting and take steps to prevent it. I would think NOW would be a good time to get started and not 150 years from now.
As for the rest it is bull. We have never been the cause of climate change which has been going back and forth, warm to cold, for millions of years. We have no way to accelerate it or slow it. It would be a waste of money to try.
