Guess so. What is coming, is going to be bad enough without exaggeration.
Tens of millions of people are going to have to move or get huge amounts of aid. That's already underway. And life is going to be a lot more interesting on a lot of coastlines, notably the U.S. Gulf coast. Already, insurance rates are skyrocketing as destructive storms become more frequent and unpredictable (they run on temp differences, and as the sea warms up things get interesting)
The Sahel is going to be desert, and the American west is going to get drier. Grazing land is going to get semi-arid, semi-arid will go to desert, and some cropland will go to grazing. Same time this is going on, warmer winters are reducing snowpack, and therefore spring runoff to rivers, and the great aquifers are being drawn down faster than they can regenerate.
Not a good thing. In some places, though, it might actually get better. But historically, climate dislocations are associated with wars, human migration, and disorder. The great disruptions and prolonged dark age starting around 1200 BC seems to have been triggered by a series of climate changes.
People aren't just going to sit down and die, if their land suddenly becomes unproductive.
It's going to be gradual. No one is going to be swept away. And so far, it's not much, mostly due to thermal expansion. Melting of continental glaciers is just beginning. Melting of polar sea ice and Antarctic ice shelves don't raise ocean levels at all. The problem is displacement, not drowning.
Hysteria is bad because it blinds us to the very real disasters that will happen if things go on as they are. I blame extremists on both sides.
