Volcanic eruptions are important for world climate

Volcanic eruptions are important for world climate
Copenhagen, Denmark (SPX) Jul 09, 2015 - Large volcanic eruptions release huge clouds of ash and acid into the atmosphere. These clouds spread across the globe and block out the Sun, resulting in a colder climate for decades afterwards. Climate researchers have known this for a long time, but new research from the Niels Bohr Institute shows that the effects of volcanic eruptions are greater than previously thought and that they have in ... morehttp://www.terradaily.com/reports/Volcanic_eruptions_are_important_for_world_climate_999.html

Volcanic eruptions that changed human history
Reno NV (SPX) Jul 09, 2015 - It is well known that large volcanic eruptions contribute to climate variability. However, quantifying these contributions has proven challenging due to inconsistencies in both historic atmospheric data observed in ice cores and corresponding temperature variations seen in climate proxies such as tree rings. Published in the journal Nature, a new study led by scientists from the Desert Res ... morehttp://www.terradaily.com/reports/Volcanic_eruptions_that_changed_human_history_999.html

Timeline links volcanic eruptions to centuries of cold temp extremes
New Haven CT (SPX) Jul 09, 2015 - A new study reorders the timing and reveals the climate impact of nearly 300 major volcanic eruptions worldwide, dating back to the early Roman period. The analysis, published in the journal Nature, resolves longstanding inconsistencies between historic atmospheric sulfate data taken from ice cores and corresponding temperature data derived from tree rings and other sources. The new chrono ... more  http://www.terradaily.com/reports/New_timeline_links_volcanic_eruptions_to_centuries_of_cold_temperature_extremes_999.html
