Tipping Points Preceded Major Climate Warming Events, Study Finds.

Three periods of extreme warming in the earth’s past were preceded by climate tipping points involving the release of greenhouse gases, according to research from Wageningen University & Research and Utrecht University. The study is the first to draw a straight line between decreased stability in the climate system and those warming periods. The findings follow another study indicating that current levels of global warming could trigger climate tipping points, with full avoidance only possible if global heating is kept below 1 degree Celsius above pre-industrial levels.
