Time of Year Important in Projections of Climate Change Effects On Ecosystems

ScienceDaily (Feb. 15, 2012) — Does it matter whether long periods of hot weather, such as last year’s heat wave that gripped the U.S. Midwest, happen in June or July, August or September?

Scientists studying the subtle effects of heat waves and droughts say that when such events happen makes a big difference.

Based on more than 25 years of data from the National Science Foundation (NSF) Konza Prairie Long-Term Ecological Research (LTER) site in Kansas–one of 26 such NSF LTER sites across the globe–ecologists looked at how droughts and heat waves affect grass growth during different months of the year.

The journal Proceedings of the National Academy of Sciences (PNAS) published their results today.
