The world is set to have been hotter in 2023 than in any other year on record, scientists have declared, before a landmark climate summit this month. From a report: “We can say with near certainty that 2023 will be the warmest year on record, and is currently 1.43C above the pre-industrial average,” said Samantha Burgess, the deputy director of the Copernicus Climate Change Service. “The sense of urgency for ambitious climate action going into Cop28 has never been higher.” The Copernicus scientists found last month was the hottest October on record globally, with temperatures 1.7C above what they were thought to have been during the average October in the late 1800s.
By burning fossil fuels and destroying nature, humans have pumped heat-trapping gases into the atmosphere that have raised the temperature of planet by 1.2C since the Industrial Revolution. The global temperature anomaly for October 2023 was the second highest across all months in its dataset, the scientists found, behind only the month before. “The fact that we’re seeing this record hot year means record human suffering,” said Friederike Otto, a climate scientist at Imperial College London. “Within this year, extreme heatwaves and droughts made much worse by these extreme temperatures have caused thousands of deaths, people losing their livelihoods, being displaced etc. These are the records that matter. That is why the Paris agreement is a human rights treaty, and not keeping to the goals in it, is violating human rights on a vast scale.”
