WASHINGTON — Month after month, global temperatures are setting new records. Meanwhile, scientists and climate policymakers warn of the growing likelihood that the planet will soon exceed the warming target set at the landmark Paris 2015 climate talks. Making sense of the run of climate extremes may be challenging for some. Here’s a look at what scientists are saying. The European Union’s climate-watching agency Copernicus declared last month that it was the hottest May on record, marking the 12th straight monthly record high. Separately, the World Meteorological Organization estimated that there’s almost a one-in-two chance that average global temperatures from 2024 to 2028 will surpass the hoped-for warming limit of 1.5 degrees Celsius (2.7 Fahrenheit) since pre-industrial times that was agreed in the Paris talks. And one more: Earth warmed at a slightly faster rate in 2023 than 2022, a group of 57 scientists determined in a report in the journal Earth System Science Data.
