The United Nations Intergovernmental Panel on Climate Change report of Monday 8 October 2018 titled “Global Warming of 1.5 °C” warns of dire consequences if world governments do not begin immediately to cut CO2 emissions. “Human activities are estimated to have caused approximately 1.0°C of global warming above pre-industrial levels, with a likely range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate. (high confidence).”
