Current decade of global warming unprecedented in Earth's climate history

Scientists studying the Earth's climate history have claimed that the current decade of warming is exceptional relative to any period since before the last ice age, about 125,000 years ago. While it is impossible to prove exactly how hot it might have been thousands of years ago, paleoclimatologists are confident that the recent heat would have been all but impossible over most of those millennia. The current spike in temperatures is caused by the burning of fossil fuels and emissions of greenhouse gases, making it distinct from any previous warm period.
