Underwater volcanoes could be affecting climate change

The Week: A new study suggests that climate change may actually begin underwater. Researchers at Columbia University's Lamont-Doherty Earth Observatory found that volcanic eruptions beneath the ocean's surface could impact the process of climate change. The study, published in the journal Geophysical Research Letters, suggests that climate analysts add volcanic consideration into predictive climate change models. "People have ignored seafloor volcanoes on the idea that their influence is small -- but...

Undersea Volcanoes May Be Impacting Climate Change

Time: A new study claims that volcanic eruptions along the ocean floor may impact earth's climate cycle and that predictive models, including those that analyze humanity's impact on climate change, may need to be modified. "People have ignored seafloor volcanoes on the idea that their influence is small--but that's because they are assumed to be in a steady state, which they're not,' said Maya Tolstoy, a geophysicist and author of the study that appeared in Geophysical Research Letters and was also...

Volcanoes Can Mitigate Climate Change?

Nature World: Small volcanic eruptions over the years may actually helped slow climate change. That's at least according to a new study which details how minor eruptions between 200 and 2013 may have directly cooled the average global temperature. The study, published in the journal Geophysical Research Letters, describes how volcanoes blast helpful particles, called aerosols, into the air during an eruption. When these sulfer dioxide aerosols reach the stratosphere (the second layer of our atmosphere), they...

Small volcanoes could slow down global warming: study

Agence France-Presse: SMALL VOLCANIC ERUPTIONS could be slowing global warming by spewing out sulphur molecules that can reach the upper atmosphere and reflect sunlight away from the Earth, US scientists said on Tuesday. Researchers have long known that volcanoes can protect against global warming, but they did not think that minor eruptions did much to the atmosphere. The latest findings in the journal Geophysical Research Letters show that small volcanic eruptions have deflected almost twice the amount of solar radiation...
