Choose your pick.
2. You don't get to advocate the end of fossil fuels by spreading disaster scenarios while ignoring the very real human costs that would result from what you are advocating.
2. If you want to talk about "real human costs" of climate policy, you might want to pick a country that is not built upon a coastal flood plain that is routinely flooded[1]: Bangladesh is going to be among the countries hit hardest by climate change[2].
It makes me suspect that you don't care about human costs at all. On the other hand it did help me writing this rebuttal, so I guess all is well after all.

Well, I actually do care about people. So, there's that.
"In 1998, over 75% of the total area of the country was flooded, including half of the capital city Dhaka. ... 30 million people were made homeless and the death toll reached over a thousand."
That's sad, all right. How many routinely died in famines before the advent of modern, high-energy, mechanized agriculture?
Hint: a lot more than a thousand.

Try ten million. And that was just one such event. They were routine in the days before mechanized agriculture and mechanized food transport. Happened all the time. Note that the article tries to blame this on the British (and they do appear to have been rather callous), but the primary cause was the failure of the monsoon. Nowadays if a monsoon fails you can truck in food from somewhere else. You can't do that without fossil fuels or some equivalent. Not to any real degree.
"It makes me suspect that you don't care about human costs at all. "
I'm not the one who wants to sentence the bulk of the human race to a preindustrial scenario involving periodic mass starvation. So, no.
Until you actually demonstrate functional and economic alternatives, that is exactly what it means.
You aren't a starving peasant in Bangladesh, dude.
Reducing energy consumption to any significant degree will doom millions of people to an unpleasant death.
And no, solar and wind won't do it. At least not earth-based solar. Space-based solar might do the trick, but the risks and costs would be extremely high.
There is exactly one feasible alternative to fossil fuels, and that is nuclear.
