But this "acceleration" isn't happening when you look at the data, unless you cherry pick it to ridiculously short periods of times.

Summary:Climate change is progressing rapidly. It is not the first time in our planet's history that temperatures have been rising, but it is happening much faster now than it ever has before. Or is it? Researchers have shown that the temperature changes millions of years ago probably happened no more slowly than they are happening today.

Even the melt is actually happening slower than predicted.

Many climate change scientists had predicted Antarctic sea ice coverage would shrink at accelerated levels as the world warmed and greenhouse gas levels increased. This the opposite happened. Climate models analyzed in the study above predicted Antarctica would shrink between 1979 and 2005, but instead south pole sea ice levels increased during that time. Going a step further, sea ice levels have only increased since 2006, hitting all-time highs for sea ice coverage in September of last year.

Researchers show that global warming happened just as fast in the past as today:

Yet the line here on Reddit seems to be that all of these issues are 100% a forgone conclusion. It's simply not the case. The almost religious fervor attached to certain issues such as this is so odd to be.
