The Copernicus Climate Change Service reported that average global temperatures during the year ending at the end of May exceeded the pre-industrial revolution average by about 1.63 degrees Celsius, making it the warmest period since data records began in 1940.
The average of the past 12 months does not mean that the world has exceeded the global warming threshold of 1.5 degrees Celsius, which measures the average temperature over decades, and scientists warn of the consequences of exceeding it that are more extreme and cannot be addressed.
In a separate report, the United Nations World Meteorological Organization indicated that there is a chance of about 80 percent of recording an average temperature temporarily exceeding 1.5 degrees Celsius above pre-industrial levels during at least one year of the next five years, up from a chance of about 66 percent. last year.
Speaking about these results, Guterres warned of the speed with which the world is moving in the wrong direction away from the stability of the climate system.
“In 2015, the chance of this overshoot occurring was close to zero,” he said in a speech on World Environment Day.
With time running out to reverse course, Guterres urged reducing global fossil fuel production and use by about 30 percent by 2030.
“We need an exit from the highway to climate hell,” he said.
He continued: “The battle for 1.5 degrees Celsius will be won or lost during the current decade.”
