UN Intergovernmental Panel on Climate Change Report
The UN's final IPCC report warns that drastic action must be taken immediately, but staving off disaster is within humanity's grasp. The world needs immediate action now to defuse a "climate time bomb" that will unleash catastrophic environmental effects and climate breakdown, United Nation (UN) scientists have said in the last of its four major assessment reports to governments on Monday (March 20).
Governments must make "rapid, deep and immediate" cuts to global carbon dioxide emissions, a greenhouse gas that is the largest contributor to human-caused climate change, in order to start to decrease annual emissions by 2025 and halve them by 2030, according to the final summary report by the UN's Intergovernmental Panel on Climate Change (IPCC). These carbon dioxide cuts must be made globally and across all industries if temperature changes are to remain at or below the dangerous threshold of 2.7 degrees Fahrenheit (1.5 degrees Celsius) above pre-industrial temperatures, the IPCC said.
Scientists have warned that crossing this 1.5 C threshold greatly increases the risks of encountering tipping points that could unleash irreversible climate breakdown — such as the total collapse of most of the Greenland and West Antarctic ice sheets; extreme heat waves; severe droughts; water stress; and extreme weather across large parts of the globe.
