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.
Last month the USDA announced plans to create seven climate change “hubs” to provide outreach and training on behalf of the farm, agriculture and forestry sectors in the seven regions they serve. The effort represents a realignment of existing government resources rather than new investment. It’s a welcome development, and a model for other government agencies to collectively address climate change-related impacts outside the realm of agriculture.
Antarctic krill are the keystone species in the Antarctic ecosystem, directly transferring energy in the form of carbon from algae to top predators. Ocean circulation is an important contributor in structuring and maintaining the circumpolar and the regional distribution of Antarctic..
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…
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”
