This isn't the greatest illustration: it only goes back 20,000 years. That's only a minuscule portion of the Earth's history, and even for humans it's just a fraction of our history (humans are roughly 2M years old). Of course, going back to the climate the Earth had in the Cambrian era, for instance, probably would not be comfortable to humans at all, but still, humans have survived for a much longer time than is illustrated here. Human civilization, OTOH, occupies about half the time period shown here. The thing that's most important about climate change is: how will it affect human settlements where they're located now? You can't just pick up whole cities with billions of people and move them, and many (most?) of the cities are close to water.

Way to wait a week to sneak this in. Anti-science thrives when it avoids scrutiny. If you think going back more than 20k years would in any way change the entire point of the cartoon[1], then by all means do the research, draw the graph and show where it's wrong. [1] hint: rate of change is important.

  I waited a week because posting it sooner gets me "You're posting too fast. Slow down". So some of my replies are quick, others get queued up for days. Fix the site, don't complain to me. Anyway, it's not anti-science. It's well-known that the earth was hotter during the time of the dinosaurs. Sure, rate of change is important, but as I said in the end, the biggest problem for humans is rising sea levels, because of where humans live. Worse storms are also a big problem, though here again where humans live is a big problem since they tend to live on coasts and storms usually hit there.

    Posting too fast clears in an hour or two, not days. Learn how the site works, don't complain to me. It's classic climate denial to continue to harp that the earth was hotter in the past so somethingsomethingsomething look over there and ignore the fact that the rate of change this century, not looking back a million years, is the point of the comic.
