Final 12 months was among the many hottest ever recorded on the planet, and the oceans’ temperature reached a historic excessive — one more signal of the worsening local weather disaster attributable to people.
In a report launched Thursday by the Nationwide Oceanic and Atmospheric Administration, scientists discovered that 2021 was the sixth-warmest 12 months on document. Total, the previous eight years have been the most well liked years since record-keeping started in 1880, in response to the same evaluation launched Thursday by NASA.
Earth’s common land and ocean floor temperature was 1.5 levels Fahrenheit above the 20th century common.
And temperatures on the earth’s oceans reached a document excessive. Excessive ocean warmth can contribute to sea-level rise, NOAA mentioned, and trigger more-severe storms and floods.
“Science leaves no room for doubt: Local weather change is the existential risk of our time,” NASA administrator Invoice Nelson mentioned in a information launch. The year-after-year temperature highs for the planet “[underscore] the necessity for daring motion to safeguard the way forward for our nation – and all of humanity,” he mentioned.
NASA’s scientists pointed clearly to the reason for the worsening local weather disaster: “human actions which have elevated emissions of carbon dioxide and different greenhouse gases into the ambiance.”
International warming fuels lethal local weather disasters, together with intense droughts, excessive warmth, worsening wildfires and more-powerful storms and floods.
