will suffer.

. . . except only those who have less than a couple of decades left anyway.

When a vote no longer matters, what can a citizen truly do?

eom

Fuck the NSA...come talk to me, stalk me, spy on me, arrest me imprison me - sacrifice all that this country is supposed to stand for, finish killing its soul before the body rots entirely....hell, if you're spying on me right now Big Brother I am doubting that 1+1=3.

Domestic Surveillance can have you in jail in minutes thanks to the NDAA.

Humans have existed something like 200,000 years, for which an ice age began 110,000 years ago and ended about 12,000 years ago. That tells me that different generations have seen climate change occur at least twice.
We could truly improve our civilization by dealing with this crisis, and we will experience serious privation by simply responding to the immediate impacts, but I am also confident that we will survive.

And I am sorry, but humans without civilization to improve them are not worth existing with in the wild...a permanent state of anarchy is what is coming without drastic changes.

The species will limp along for a long time, maybe we drop down into numbers not seen since the Stone Age once more, but society is gone in less than a 100 (and maybe less than that) if we do not act and act now. There is no chance that the status quo is capable of handling what is coming down this current path...none at all.

I certainly would rather attempt to deal with the problem of climate change, but I also think that the opening sentiment of the OP, that humans have never seen the effects of climate change is empirically incorrect. The data also indicates that humans can survive climate change. As far as civilization surviving or not, we've never faced a global upheaval like this with a global civilization on the planet, so the jury is out on that one.

that account for the apparent lack of diversity that scientists find in our DNA compared to other related species. One theory concerns the apparent eruption of a super volcano in Indonesia about 70,000 years ago that brought about very sudden climate change around the world, namely a series of year-round winters. Some have estimated that the human race on the entire planet dwindled to about 2,000 members and nearly became extinct. If civilization were to break down during an ice age and the human race had to rely on hunter-gatherer activities or primitive farming under conditions of a year round nuclear winter, a whole lot of people might die. I know that if I had to rely on my hunting or farming skills for food, in an environment where most domesticated animals and hunting game have disappeared and where most domesticated crops won't sprout because of the dry or cold environment, after raiding the shelves of the local grocery store along with my neighbors I'd be dead in a matter of weeks.

Why doesn't everyone worry about the future we are leaving our children?

We can aggressively address this crisis (which we won't), or we'll turn into a carbon copy of Venus. The latter is vastly more probable.
