Existen evidencias científicas abrumadoras de que la Tierra se está calentando y una preponderancia de pruebas científicas de que las actividades humanas son la causa principal.
In 2019, air temperatures over the Arctic were the second-warmest on record, continuing a string of 6 years that have been warmer than all other periods in the historic record dating back to 1900.
Yes, human activities exert a cooling influence on Earth in several ways. Overall, this cooling influence is smaller than the warming influence of the heat-trapping gases humans put into the air.
Yes, human activity is putting carbon dioxide into the atmosphere faster than natural processes take it out. Rising carbon dioxide levels are strengthening Earth's greenhouse effect and causing global warming.
American Eunice Foote was an amateur scientist and women's rights pioneer from the mid-1800s whose experiments foreshadowed the discovery of Earth's greenhouse effect.
During active hurricane eras, a persistent zone of high vertical wind shear along the U.S. East Coast provides protection from rapidly intensifying hurricanes. With high emissions, that shear is projected to relax.
