Scientist Explains Climate Ice Core Proxies (2017)

This talk by Lonnie G. Thompson, focuses on glaciers as recorders and early indicators of climate change. The ongoing widespread melting of high-elevation glaciers and ice caps, particularly in low to middle latitudes, provides strong evidence that a large scale, pervasive and in some cases, rapid change in Earth’s climate system is underway. On Thursday…

Antarctic Volcanoes Waking up?

Nearly 100 Volcanoes Discovered Beneath Antarctica’s Ice http://blogs.discovermagazine.com/d-brief/2017/08/14/volcanoes-under-antarctica A new volcanic province: an inventory of subglacial volcanoes in West Antarctica http://www.geos.ed.ac.uk/homes/rbingha2/48_2017_Vries.pdf Scientists discover 91 volcanoes below Antarctic ice sheet This is in addition to 47 already known about and eruption would melt more ice in region affected by climate change https://www.theguardian.com/world/2017/aug/12/scientists-discover-91-volcanos-antarctica How a melting ice…

NASA Laser Reveals Miles of Greenland Ice Loss

What if you could measure a glacier in such detail that you could visualize its surface in 3D? And what if you could compare that view with data from one, two, even 20 years ago? NASA airborne campaigns like Operation IceBridge have been measuring Greenland and Antarctica’s glaciers and ice sheets with a range of…

Little Algae creates Huge Melt Feedback on Greenland Ice

Algae responsible for large albedo feedback on Greenland’s frozen surface, not only soot and dust. We believe gathering measurements from the surface of Greenland ice is fundamental to advancing our understanding of the melting Arctic. http://darksnowproject.org Video via https://www.youtube.com/user/greenman3610 Dark Snow 2017 Update “Am I really seeing that?” is a common sensation here, as below,…

Tell the Climate System Stories Again

Ever since scientists first began to explain the evidence that our climate was warming — and that human activities were probably to blame — people have been questioning the data, doubting the evidence and attacking the scientists who collect and explain it.

Climate Expert Mike Mann: Understanding Dire Climate Predictions

This 2016 lecture featuring Michael E Mann http://www.meteo.psu.edu/holocene/public_html/Mann/index.php begins with a review of the now-solid evidence for a human influence on the climate of recent decades. Such evidence includes instrumental measurements available for the past two centuries, paleoclimate observations spanning more than a millennium, and comparisons of the predictions from computer models with observed patterns…

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…

Vanishing Arctic Ice and Amplification

While heat waves and more intense storms have been directly linked to a warming Earth, new research is exploring possible impacts of an Arctic that is warming at twice the pace of the rise in global temperatures. Jennifer Francis, Rutgers University, discusses new research and efforts to understand this controversial aspect of climate change in…

Atmospheric Oxygen Decline threatens Humanity’s Existence

Study: There has been a clear decline in the volume of oxygen in Earth’s atmosphere over the past 20 years. A recently proposed model predicts a non-linear decay, which would result in an increasingly rapid fall-off in atmospheric oxygen concentration, with potentially devastating consequences for human health. We predict that humans may continue to survive…

Drew Shindell: Climate Policy to Avoid Tipping Points

Head of the SAP, Drew Shindell, talks about why a near-term climate goal is important, the main message the article aims to convey, why governments should adopt a near-term goal, and whether reducing near-term warming can prevent climate tipping points. The Climate and Clean Air Coalition’s Scientific Advisory Panel (SAP) published an article in Science…
