The last eight years have been the eighth hottest on record, a new UN report reveals, showing the world is currently in a climate crisis. He said the internationally agreed 1.5-degree limit on global warming is now “almost out of reach”.
A United Nations World Meteorological Organization (WMO) report describes how record-high levels of greenhouse gases in the atmosphere are causing sea levels to rise, melting ice to new highs, and slashing sea ice from Pakistan to Puerto Rico. It details how they amplify extreme weather events.
The grim assessment was announced on the first day of the UN’s COP27 climate summit in Egypt, calling the UN secretary-general “on track to reach an irreversible tipping point in climate chaos.” ‘ warned.
The WMO estimates that the global average temperature in 2022 will be about 1.15°C warmer than the pre-industrial average (1850-1900).
Over the past two years, a natural climate phenomenon called La Niña has kept the Earth’s temperature cooler than it would otherwise be. In addition to global warming, temperatures will continue to rise as a return to El Niño conditions is inevitable.
“The higher the warming, the worse the impact,” said WMO Director-General Professor Petteri Taalas. “Right now, atmospheric CO2 levels are so high that the Paris Agreement’s low [target] of 1.5°C has barely been met. It is the main long-term threat to countries and low-lying countries and is constantly increasing at record levels, meaning our planet is approaching an irreversible tipping point in climate chaos. We need to move from tipping point to tipping point of hope.”
Many recent reports have argued that there is “no sure path to 1.5°C” and that current levels of action suggest how close the planet is to a climate catastrophe. He aims to keep emissions down and global temperature rise from reaching a catastrophic 2.5°C.
“Those least responsible for climate change often suffer the most, but even well-prepared societies have been hit hard this year,” said Professor Taalas. Professor Mike Meredith of Ice loss is particularly alarming given its enormous impact on people, society, and the economy. If this doesn’t get the minds of the Cop27 world leaders focused, who knows? ”
