Overview There is a shrinking window of opportunity to address the climate crisis. Average global temperature is currently estimated to be 1.1°C above pre-industrial times. Based on existing trends, the world could cross the 1.5°C threshold within the next two decades and 2°C threshold early during the second half of the century. Limiting global warming to 1.5°C is still narrowly possible and will be determined by the investment decisions we make over the next decade.
