Climate Change

formerly “Climate Science” this has been updated in recognition of the fact that ALL of our articles, events, etc. involve climate sciience.  ”Climate change” is intended to suggest changing elements of the climate: e.g., shifts in global oceanic and atmospheric circulation and ensuing changes to temperature, precipitation, groundwater levels, saltwater intrusion.

The Impact of Aerosols on Climate Sensitivity Estimates. Trude Storelvmo

Assistant Professor Trude Storelvmo presents research which suggests that the cooling effect of aerosols may mask up to 0.5 degrees of warming.  The implications are significant, as efforts to abate air pollution that health officials attribute to millions of deaths each year around the global will exacerbate warming trends and suggest that equilibrium climate sensitivity is at the higher end of ranges reported in the most recent IPCC Assessment Report.

Ocean Heat Uptake, The apparent hiatus in global warming and Climate Sensitivity. Kevin Trenbeth

Kevin Trenbeth, from the National Center for Atmospheric Research (NCAR), addresses a recent and recurring question about a conjectured pause in the rise of global surface temperatures during YCEI’s workshop on “Uncertainty in Climate Change: A Conversation with Climate Scientists and Economists”

What Happens in the Arctic Doesn't Stay in the Arctic. Fran Ulmer

Fran Ulmer reminds people that “Antarctica has penguins.  The Arctic has people.”  Ms. Ulmer was a University of Alaska Chancellor and Lieutenant Governor of Alaska from 1994-2002.  She talks about the effects of climate change in Alaska where average seasonal temperatures have already increased by 4 degrees in summer and 7 degrees in winter.  Her talk is wonderful for anyone who forgets how very different the situation is at the Earth’s poles: Antarctica is uninhabited land surrounded by an ocean, whereas the Arctic is an ocean surrounded by 8 nations.
