In 1896, Swedish scientist Svante Arrhenius was the first to link a rise in carbon dioxide gas from burning fossil fuels with a warming effect. The roots of the greenhouse effect concept lie in the 19th century, when French mathematician Joseph Fourier calculated in 1824 that the Earth would be much colder if it had no atmosphere. That trapping of heat is known as the greenhouse effect. The gases absorb solar energy and keep heat close to Earth's surface, rather than letting it escape into space. Greenhouse gas levels are so high primarily because humans have released them into the air by burning fossil fuels. But those gases are now out of balance and threaten to change drastically which living things can survive on this planet-and where.Ītmospheric levels of carbon dioxide-the most dangerous and prevalent greenhouse gas-are at the highest levels ever recorded. By trapping heat from the sun, greenhouse gases have kept Earth's climate habitable for humans and millions of other species.
