Maybe you've heard that volcanic eruptions can affect climate, but new evidence But new evidence suggests that the volcano-climate relationship can go the Scientists think that the regular changes in Earth's tilt may have a big effect Here's what you can do if your social media post gets taken down. Rapid global warming has caused an increase in volcanic eruptions in the past, a new study finds But few people thought climate change could fuel volcanic eruptions before Jegen We're also on Facebook & Google+.

Evacuees numbered more than 11, people. There are many myths about volcanoes and rising temperatures. One of the most persistent is a false claim that the ash disgorged by erupting mountains is the primary driver of current climate change.

That said, there is a relationship between volcanoes and the changing environment. Evidence exists that rapid climate change has led to volcanic eruptions in the past and, conversely, that past eruptions have driven climate change.

In the Earth's history, there are plenty of links between climate change and volcanoes Of course, human activity is not affecting the eruption of these volcanoes, which are located in the "Ring of Fire" region of the Pacific. Volcanoes are more numerous there because of plate tectonics. Still, rapid climate change has been linked to volcanic activity in some areas of the globe.

A study published in September in the Proceedings of the National Academy of Sciences found that glacial retreat in Antarctica 17, years ago was connected to a series of volcanic eruptions over a year period.

Advertisement Here's how that happens. Ice and ocean water create pressure on the Earth's crust, capable of containing magma. If a glacier retreats in a relatively quick period of time, the magma is more likely to push toward the Earth's surface, said Michael Manga, a professor of earth and planetary science at the University of California, Berkeley.

Volcanoes contribute to long-term global warming and short-term global cooling When a volcano erupts, it spews ash and aerosol droplets into the atmosphere.

These are capable of cooling the planet, though typically it lasts a few days or weeks before they are removed from the atmosphere, according to the U. The airborne particles reflect more sunlight, which otherwise would warm Earth. Also emitted is sulfur dioxide gas, which can cause cooling. As the sulfur dioxide is converted into sulfuric acid, it creates aerosol droplets, which further reflect the sun's rays away from Earth and contribute to cooling. For major eruptions, such as that of Mount Pinatubo inthe cooling effects can last for years.

That eruption lowered global temperatures for three years, by as much as 1. No, volcanic eruptions will not save us from human-caused global warming. Their cooling effect is temporary. And as they cool the Earth, they belch out significant amounts of greenhouse gases. Volcanoes have driven dramatic but short-term changes to the climate in the past Past volcanic eruptions of a scale not seen in modern human history have caused dramatic changes to the planet and caused extinctions, said Manga, of Berkeley.
