Weathering of Earth by glaciers may have warmed the planet over eons by aiding the release of carbon dioxide into the atmosphere. A new study shows the cumulative effect may have created negative feedback that prevented runaway glaciation.

EasTexSteve Oh, you think so? So, by that logic, the miniscule global warming we are experiencing now should be insignificant.

EasTexSteve And, besides that, you can't have it both ways. Either glaciers contribute to global warming, or they don't.

T.E.C. - Iowa Although it needs more study, let us assume glaciers contribute to global warming. The next question is, how much! For example, the rising of mountains and the following erosion - the Himalayan being a classic example - contribute to global cooling, but it takes centuries to be significant.

It is a little like that old denier line, "Volcan...See More

Lulu Steve, what we're experiencing now is not minuscule. It is measurable over the span of years, not millennia or eons. Your argument is like saying, "I've discovered that one of my windows isn't properly insulated, therefore it doesn't matter if I turn the heat up to 90 and throw open all the windows and doors in my house."

Bob R/CA What critics of science don't seem to realize is, the Earth is indeed affected by all these factors. The sun, animals, plants, geological activity. Those factors are not new, they have been occurring for eons. Their interplay forms an equilibrium and our environment is keyed to that equilibrium.

Introduce a new factor, and that equilibrium...See More
