For the 10th consecutive month, Earth set a new monthly record for global heat — with both air temperatures and the world's oceans hitting an all-time high, the European Union climate agency said.
Most of the country is predicted to be warmer than normal with that warmth stretching north from Tennessee, Missouri, Nebraska and Nevada, along with nearly all of California, say federal forecasters.
The cooling in the Pacific Ocean has gone on for three years. Its end is usually good news for the U.S. and other parts of the world, including drought-stricken northeast Africa, scientists said.
The latest estimate from various forecast centers around the world say the planet is approaching a warming threshold international agreements are trying to prevent.
Global temperatures soared above the 20th century average last year, as the climate continues to change. It's the hottest it has been since scientists started tracking global temperatures in 1880.
