Is there any consensus that the last ice age ended because of greenhouse gases? If not, then saying global warming is caused by greenhouse gases implies that the warming that ended the last ice age was a different phenomenon. It would be strange to say that the warming of the earth that ended the last ice age was not an instance of global warming. |

:I agree with your comments, and have removed both texts in question. The first of those statements that you question is simply not true, and for the second one, see this web page: http://www.cnn.com/2001/TECH/science/03/14/greenhouse.gases.02/ |
