Summary

Geochemists have now incorporated in their models some details of the way naturally acidic rainwater dissolves rock. This weathering is part of the cycling of carbon through air, land, and ocean that has controlled climate over the eons. These researchers found how the rising of great mountains like the Himalayas can cool climate without sending Earth into an endless global ice age.
