Why even 1°C of global warming matters

The planet has already warmed 1°C from the pre-industrial period. But the question many people still ask is why does it matter? Isn’t 1 degree just small a number to be worried about? “The scales of the planet is different from the temperature scales we experience on a daily basis,” said Gavin Schmidt, director for NASA Goddard Institute for Space Studies, at the Congress International de Cambio Climatico (International Congress on Climate Change) held in Huelva, Spain last May 10-12. “One degree of warming matters. It is similar to one quarter of the ice age of 20,000 years ago to pre-industrial change,” Schmidt added. The difference of global temperature between the pre-industrial period and the last ice age is about 4-5 degrees celsius. However, 20,000 years ago, in the last quarter of the ice age, ice thawed because of an increase in carbon dioxide in the atmosphere which warmed the planet. This is according to a paper published in Nature. This warming caused the last deglaciation and within a few hundred years, seas have risen …
