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.

When Evolved Behaviors Backfire

Frogs that eat holiday lights, birds that eat plastic, and beetles attempting to mate with beer bottles are all examples of organisms that have fallen victim to what biologists call “evolutionary traps.”  Whereas natural selection typically produces organisms that behave in ways to maximize their fitness, resulting in more offspring passing their genes onto the next generation, human actions sometimes short-circuit the process…

The Importance of Model Resolution in Global Change Biology

Biologists increasingly realize that understanding the impact of global change on biological processes requires accounting for fine-grain environmental variability (Potter, Arthur Woods, & Pincebourde, 2013). Similarly, climatologists have found that increasing the resolution of climate models typically produces better simulations of climate and precipitation…

Reduction in Carbon Uptake During Turn of the Century Drought. Christopher Williams

Clark University’s Christopher Williams trained as a land surface hydrologist and terrestrial ecosystem ecologist.  Clark University’s website reports on his work:

“Chris investigates how earth’s biosphere responds to natural and human perturbations such as severe drought events, bark beetle outbreaks, fires, harvesting, and land cover changes.”

Global Carbon Dioxide Emissions from Inland Waters

Carbon dioxide transfer from inland waters to the atmosphere is a significant component of the global carbon cycle. Global estimates of CO2 transfer have been hampered, however, by a lack of a framework for estimating the inland water surface area and gas transfer velocity and the absence of a global CO2 database. Here we report regional variations in global inland water surface area, dissolved CO2 and gas transfer velocity.

What Climate Models Need to Know About the Sub-Polar Oceans. Peter Rhines

Mary Louise Timmermans introduces Peter Rhines who shares his latest field observations from the subpolar Atlantic and what they offer climate modelers. Peter’s talk covers introductory concepts related to Arctic climate and how it influences atmospheric and oceanic circulation as well as more technical information on ocean circulation dynamics which exert tong controls yet are under-represented in IPCC-class coupled climate models.

Aerosol Effects on Ice Clouds: Climate Forcing and Potential for Geoengineering

Trude Storelvmo, Department of Geology & Geophysics at Yale University, explains how various species of aerosol differentially effect cloud formation and the consequences for radiative forcing. She further explains some of the implications of those findings for proposed geo-engineered options such as cloud seeding to counteract the effect of the buildup of greenhouse gases.
