I wonder if people understand that the temperature difference between frozen and unfrozen is very little. And that once that point is breached it's very hard to go back. Once the ice starts to melt then expect all of it to melt, eventually.
We've reached the melting point and we need to get ready for the consequences.
- perl4ever 8y agoI'm not sure what you mean by "the temperature difference between frozen and unfrozen is very little". This sounds as though you are implying it is very easy to go from frozen to melted. When ice melts to water, it absorbs a fair amount of energy without changing temperature, is my recollection of high school physics.
- graeme 8y agoI think that mean that if daytime temperature in a place is 1 degree celsius, no ice will remain in the long run. This is true if there are no seasons, but of course more ice will form in the winter. But it's still worth thinking about over the long run. You don't need 30 degrees celsius to melt ice - 1 degree will do. It will just be slower.
- WheelsAtLarge 8y agoCorrect, that's my point.
- perl4ever 8y agoThis bothers me in the same way as when people say that a 20% gain in something doesn't get you back from a 20% loss. It's technically true, but it has a fallacious flavor to me because it's based on an incorrect choice of mental anchor. It's true that it doesn't take a significant change in temperature to melt ice, but temperature is not "what it takes" - it takes heat.
- graeme 8y agoBut the point is that a temperature of 1 degree celsius is constant heat which will eventually melt all the ice. That's what outdoor temperature from the sun is, right?
