Warmist David Biello: Natural warming at the end of the last Ice Age "ultimately, cleared the way for human civilization"

Take, for example, the end of the last Ice Age, in which great ice sheets that had been covering some 30 percent of the globe retreated over the course of thousands of years. That led to extinctions, range shifts and, ultimately, cleared the way for human civilization (and the seven billion of us on the planet today.) Our collective impact has now turned more than 40 percent of the globe to our uses—whether agriculture or cities—and plants will have to move much faster than they did as the glaciers shrank to keep up. In fact, to keep up with the climate change we’re creating by burning fossil fuels, flora and fauna will have to move on the order of decades rather than millennia.

...The alternative is to continue as we have, which will keep us on track to kill off 75 percent of the known species on the planet.
