Cleaner Air, The Ocean, and Global Warming

Reductions in sulfur dioxide (SO2) emissions in recent years, for cleaner air, mainly in South East Asia due to a severe manufacturing sector slowdown and pollution policy changes (1,2) may attribute to current warming, since the phenomena called global dimming is involved. The first policies to address air pollution in the 20th century, originated after…

NASA/NSIDC: 2016 Arctic sea ice wintertime extent hits another record low

  2016 Arctic sea ice wintertime extent hits another record low By Maria-Jose Viñas, NASA’s Earth Science News Team Excerpt Arctic sea ice appears to have reached a record low wintertime maximum extent for the second year in a row, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.…

Ice sheets may be hiding vast reservoirs of methane

The study indicates that under the frigid weight of Barents Sea Ice sheet, which covered northern Eurasia some 22 000 years ago, significant amounts of methane may have been stored as hydrates in the ground. As the ice sheet retreated, the methane rich hydrates melted, releasing the climate gas into the ocean and atmosphere for…

AGU 2015: Alaska’s thawing permafrost Latest results and future projections

Alaska’s permafrost is starting to thaw as the climate warms, and scientists project there will be even greater thawing of the frozen soils in the coming decades, releasing carbon into the atmosphere, and impacting ecological systems and infrastructure. A panel of permafrost experts will unveil new findings about permafrost degradation in Alaska, where permafrost covers…

Research links abrupt paleoclimatic change to possible methane hydrate destabilization

Using a core sample from the Santa Barbara Basin, UCSB researchers decipher the history of paleoclimate change with surprising results By Julie Cohen (UCSB): Global climate change isn’t new — the phenomenon has been around for millions of years. But now, a core from the ocean floor in the Santa Barbara Basin provides a remarkable…

Fossil Fuel Emissions could Eliminate the Antarctic Ice sheet entirely, causing about 58 m Sea Level Rise

A new open access study in Science Advances concludes that a warming beyond the 2°C target would potentially lead to rates of sea-level rise dominated by ice loss from Antarctica, and continued CO2 emissions from fossil sources could cause additional tens of meters of sea level rise, over the next millennia and eventually ultimately eliminate the…

Sudden ice loss acceleration at the Southern Antarctic Peninsula detected

ESA posted an update on Antarctic ice loss on 22 May 2015. Above animation shows how warm ocean water penetrates the glacier grounding line through basalt melt, threatening speed up of glaciers, discharged into the ocean. A recent acceleration in ice loss in a previously stable region of Antarctica has been detected by ESA’s ice mission. The…

David Archer – Subsea Permafrost and the Methane Cycle on the Siberian Continental Shelf

ARCTIC-WISE: Bridging Northern Knowledges of Change Subsea Permafrost and the Methane Cycle on the Siberian Continental Shelf: Predictive Modelling for Climate Change David Archer, Geophysical Sciences, University of Chicago Tuesday, March 10, 2015, 5-6:30 pm A numerical model called SpongeBOB is used to simulate the hydrology and methane cycle on the Siberian continental shelf. Lowered…

ScienceCasts: Climate Change and the Yin-Yang of Polar Sea Ice


Arctic and Antarctic sea ice are both affected by climate change, but the two poles of Earth are behaving in intriguingly different ways.

Bill McGuire: Modelling suggests with ice cap melt, an increase in volcanic activity

ClimateState interviewed Bill McGuire, Emeritus Professor of Earth Sciences at the University College London, one of Britain’s leading volcanologists and contributing author to the 2011 IPCC report. He called for an early tsunami warning system (2004, The Guardian) and warned in his book The Waking Giant, of the Earth response (more earthquakes, tsunamis and landslides)…

Experts: Arctic craters could be ‘Visible Effect’ of Global Warming

The preliminary results from scientists studying the mysterious holes (craters), that began emerging in recent times in Siberia, indicate that climate change may be a cause. The Russian crater research team led by Alexei Plekhanov of the Scientific Centre of Arctic Studies, explained a possible mechanism, in a Nature interview. The past two summers were…

Why is Antarctic sea ice expanding?

By Laura Naranjo (NSIDC), first published January 31, 2014. In the following  an edited version, reposted here with permission. Antarctic sea ice is ruled by very different systems than Arctic sea ice. The reasons behind this increase are complex, and several recent studies show that scientists are still trying to understand them. Ice and wind Atmospheric…

New mechanism uncovered, causing potentially rapid Antarctic Glacier melt

An Australian-led research team found that sea levels may rise much faster than previously predicted by models, because changes by disruptive westerly winds, weren’t taken into account. Conservative estimates so far, projected irreversible melting in the course of a few centuries, depending on the temperature increase. Related Each degree of global warming might ultimately raise…

With further Arctic Amplification, How fast will Greenhouse Gas emissions accelerate in the Arctic Circle?

Introduction to Methane Hydrate “Methane Hydrates and Contemporary Climate Change” (2011) IDENTIFICATION This post “A Mechanism for Shallow Methane Hydrate Dissociation”, explores possible mechanism which could release vast quantities of shallow Methane Hydrate into the ocean and atmosphere.       CH4 Release The following studies explore the release of CH4 emissions in the Arctic region.
