There are many good arguments against GW, this isn’t one of them. Weather and climate are very different things, even a rudimentary knowledge of either subject should make this clear.
Al Gore, the opportunist that he is, is actually right about the assertions that he made in his book. A rise in temperatures could cause an increase in intensities of both rain and snow storms. Heat is what causes water to evaporate, heat is what allows air to hold water, heat is what causes that water vapor to rise in the atmosphere and then fall as either rain or snow. The average temperature has only risen 1 degree according to climatologist so 27 is now 28, still cold enough to snow. So pointing to a snowstorm as evidence against GW only shows your ignorance of the subject.
