What’s Happening to the Greenland Ice Sheet? (October 2017)

The Greenland ice sheet is one of the largest contributors to global sea level rise, and if completely melted, could add ~7 meters to sea level. In recent years, the imbalance of the ice sheet has increased with warmer atmospheric conditions. In this talk, Visiting Assistant Professor Samiah Moustafa describes the field’s current knowledge on…

Arctic Atmospheric Circulation, Freshwater and Sea Surface Height

NASA 2012: The transpolar drift (purple arrows) is a dominant circulation feature in the Arctic Ocean that carries freshwater runoff (red arrows) from rivers in Russia across the North Pole and south towards Greenland. Under changing atmospheric conditions, emergent circulation patterns (blue arrows) drive freshwater runoff east towards Canada, resulting in freshening of Arctic water…

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…

AGU 2015: Eric Rignot – Ice Sheet Systems and Sea Level Change

Scientific Discipline Cryosphere Speaker Eric Rignot (NASA Jet Propulsion Laboratory) Abstract Modern views of ice sheets provided by satellites, airborne surveys, in situ data and paleoclimate records while transformative of glaciology have not fundamentally changed concerns about ice sheet stability and collapse that emerged in the 1970’s. Motivated by the desire to learn more about…

Why 2°C Global Warming is Highly Dangerous

Recently, James Hansen the former director of NASA GISS published new study findings about future sea level rise, ice melt, and temperature changes, as well as the possible implications for future climate. Above video highlights a part of a talk Hansen held on December 1, 2015 at the Paris climate change conference (COP21). The take…

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. OBSERVATION…

Global Warming Speeds Up Methane Emissions from Freshwater

By Tim Radford (Climate News Network): Scientists think the amount of methane emitted to the atmosphere from freshwater ecosystems will increase as the climate warms, triggering further warming. LONDON, 20 March – British scientists have identified yet another twist to the threat of global warming. Any further rises in temperature are likely to accelerate the release of methane from…

Thawing Permafrost Could Release Vast Carbon Deposits, Diseases

by Science World Report | January 8, 2014 | Release URL Dr Guido Grosse has been studying the Arctic for fourteen years to find out how the frozen ground, known as the permafrost, is reacting to an environment that is getting hotter all the time. The samples he has drilled out – in regions so…
