I wonder if this is how the pendulum swings from interglacial to glacial periods. More water vapor in the atmosphere means heavier rains overall and heavier snowfall in polar regions. More snow takes longer to melt in the summer making it more likely that snow remains to be buried by more snow the next winter. Increased albedo of polar regions reduces global temperature making winter colder allowing the ice caps to creep towards the equator.
I think it is good to remember that Earth has cyclic glacial periods. We just happen to live during a warm period.
- Timon3 3y agoThis feels a lot like someone saying "Volcanoes have periods with high pressure and low pressure. We just happen to live during a high pressure period." in Pompei, as it ignores the problem in-between: the current change in glacial period is unprecedented for natural cycles.
- tastyfreeze 3y agoIs it though? The Earth has been ice free for 85% of its history. That makes the hysteria over climate change look like freaking out about summer coming around because its been cold for a few months. https://en.wikipedia.org/wiki/Greenhouse_and_icehouse_Earth?wprov=sfla1 https://en.wikipedia.org/wiki/Greenhouse_and_icehouse_Earth?...
- Timon3 3y agoThis is a non-sequitur. I explicitly stated that the rate of change is the problem. Why does it matter how often the earth has been ice-free? Do you understand the difference between a value over time, and its derivative?
