Features on Mars Match Climate Model Predictions

Scientific modeling methods that predicted climate change on Earth have been found to be accurate on Mars as well, according to a paper presented at an international planetary sciences conference Tuesday.

An international team of researchers from the Planetary Science Institute in Tucson, working with French colleagues, found that an unusual concentration of glacial features on Mars matches predictions made by global climate computerized models, in terms of both age and location.

PSI Senior Scientist William K. Hartmann led the team, which included François Forget (Université Paris), who did the martian climate modeling, and Veronique Ansan and Nicolas Mangold (Université de Nantes) and Daniel Berman (PSI), all of whom analyzed spacecraft measurements regarding the glaciers.

“Some public figures imply that modeling of global climate change on Earth is ‘junk science,’ but if climate models can explain features observed on other planets, then the models must have at least some validity,” said team leader Hartmann.
