Terrestrial climate models are good and on Mars

The international research team led by William Hartmann of the Planetary Science Institute (USA), found that an extraordinary concentration of glacial formations on Mars concur with the predictions of computer models of the global climate of the Earth.

Terrestrial climate models are good and Mars Dmitri Tselikov Methods of scientific simulations that predict climate change on Earth, have proved their worth on Mars.
