A headline-making article by Sherwood, et al. in the January issue of Nature ascribes the wide spread in climate sensitivities reported by global circulation models (GCMs) to how they account for atmospheric convective mixing, a process that controls cloud formation in the lower troposphere…
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.
Community ecology seeks to untangle structural patterns and underlying biological mechanisms across time and space. Though developed for studies above ground, community ecology provides an equally relevant framework for looking at the below ground world, a realm that’s now understood to store and cycle most of Earth’s organic carbon.
Yale Professor Ron Smith speaks on Climate Change in New England at a A Town Hall Meeting, entitled, “Climate Change in New England: What’s Next?” which explores how global warming will affect New England in the 21st century and how the region is preparing for the coming changes.
A changing climate effects the availability of water, agriculture, and virtually everyone on the planet. To predict changes in vegetation cover and adapt water usage appropriately it’s necessary to constrain changes in evaporative flux. Measuring evaporation is more challenging than other components of the hydrologic
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.
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”
Klaus Keller is an associate professor in the Department of Geosciences at Penn State University and an adjunct professor in the Department of Engineering and Public Policy at Carnegie Mellon University.
In a simple but important analysis, Mora and colleagues analyzed climate projections to identify when future warming will exceed the climate envelope of the past 150 years. They used multiple models (39) and seven climate variables (such as near-surface temperature …
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.
William Nordhaus is the Sterling Professor of Economics at Yale University and author of over 20 books, including the recently published “The Climate Casino: Risk, Uncertainty, and Economics for a Warming World.” His DICE model is one of the first and still most widely utilized integrated assessment models for considering the relationships between climate change, energy consumption and economic impacts. What is really relevant to the discussion of uncertainty, says Professor Nordhaus, is an understanding of statistics, which is the subject of his talk.
