AGU 2015: Jennifer Francis recent studies on Weather Blocking Patterns

Recent Changes in Blocking Characteristics Assessed Using Self-Organizing Maps Speaker: Jennifer Ann Francis Blocking anticyclones are known to be associated with persistent weather patterns that often lead to extreme weather events. An outstanding question, however, is whether the frequency and/or intensity of these dynamical features are changing in response to human-caused climate change, and in…

Arctic Sea Ice Reaches 2015 Minimum Extent

Arctic Sea Ice Summertime Minimum Is Fourth Lowest on RecordAccording to a NASA analysis of satellite data, the 2015 Arctic sea ice minimum extent is the fourth lowest on record since observations from space began. The analysis by NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado at…

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. Visit http://science.nasa.gov/ for more. Why Increasing Antarctic Sea Ice Doesn’t Mean Climate Change Isn’t Happening http://www.businessinsider.com/antarctic-sea-ice-climate-change-2014-12

ScienceCasts: The Cloudy Future of Arctic Sea Ice

As climate change continues to hammer Arctic sea ice, pushing back its summertime boundaries to record-high latitudes, NASA is flying an innovative airborne mission to find out how these developments will affect worldwide weather. NASA: Oct 15, 2014: Climate change is a global phenomenon, yet Earth scientists are keeping a wary eye on one place…

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

Climate State 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…
