We are not measuring things on a geological scale, but in human terms. So your argument is invalid. During most of the 4.543 billion years that earths exists, it was not habitable by humans. And even during long periods when earth was more or less habitable, most places where people live now, were under water or otherwise inhabitable. Also, please google "xkcd 1732" and watch, then think again.
Since even the president of the US is convinced that global warming is a Chinese hoax, we have to be impressed by the way China is playing this game. The Chinese manage to really create ever warmer weather year after year, just to fool us into thinking global warming is real. They are truly brilliant.
Hard to say what's more silly: changing some terms that have no derogatory meaning when used in programming environments, or getting angry about such a small change. C'mon people. Take a deep breath and relax. There are much bigger problems to worry about.
