Hot Summer Mess: New Climate Models Exaggerate Midwest Warming By 6X

For the last 10 years, I have consulted for grain growing interests, providing information about past and potential future trends in growing season weather that might impact crop yields. Their primary interest is the U.S. corn belt, particularly the 12…

More ecosystem engineers create stability, preventing extinctions

(Santa Fe Institute) Biological builders like beavers, elephants, and shipworms re-engineer their environments. How this affects their ecological network is the subject of new research, which finds that increasing the number of “ecosystem engineers” stabilizes the entire network against extinctions.

Are New Extreme Global Warming Projections Correct? – EcoWatch

By Jeff Berardelli For the past year, some of the most up-to-date computer models from the world’s top climate modeling groups have been “running hot” – projecting that global warming may be even more extreme than earlier thought. Data from…

Why are the offspring of older mothers less fit to live long and prosper?

(Marine Biological Laboratory) In a new study in rotifers (microscopic invertebrates), scientists tested the evolutionary fitness of older-mother offspring in several real and simulated environments, including laboratory culture, under threat of predation in the wild, or with reduced food supply. They confirmed that this effect of older maternal age, called maternal effect senescence, does reduce evolutionary fitness of the offspring in all environments, primarily through reduced fertility during their peak reproductive period. They also suggest an evolutionary mechanism for why this may occur.

Some new climate models are projecting extreme warming. Are they correct? – Yale Climate Connections

In the Arctic, spring snowmelt triggers fresh CO2 production

(San Diego State University) Studies have shown the Arctic is warming roughly twice as fast as the rest of the world, and its soil holds twice the amount of carbon dioxide as the atmosphere. New research from San Diego State University finds that water from spring snowmelt infiltrates the soil and triggers fresh carbon dioxide production at higher rates than previously assumed.
