UCLA life scientists provide important new details on how climate change will affect interactions between species in research published online May 21 in the Journal of Animal Ecology. This knowledge, they say, is critical to making accurate predictions and informing policymakers of how species are likely to be impacted by rising temperatures.

“There is a growing recognition among biologists that climate change is affecting how species interact with one another, and that this is going to have very important consequences for the stability and functioning of ecosystems,” said the senior author of the research, Van Savage, an assistant professor of ecology and evolutionary biology and of biomathematics at UCLA. “However, there is still a very limited understanding of exactly what these changes will be. Our paper makes progress on this very important question.” (more…)

Geophysical Sciences Professor David Archer polled the 200 students in one of his Global Warming classes about whether they believed that humans have had an impact on climate. Approximately 90 percent of the students responded “yes,” reflecting the lessons of climate simulations that Archer had shared earlier with the students.

Those computer simulations are able to reproduce the trend toward rising temperatures, but only when they include data on rising carbon dioxide concentrations in the atmosphere. Simulations that omit the CO2 data do not accurately reproduce the changes. Archer says the link helps reveal carbon dioxide emissions as “the smoking gun” behind global warming and climate change.
