Was it really warmer? I did not notice. I welcome additional heat, if there really is any, since it is too cold where I live in southern Canada. This morning I woke to a temperature of -18 C or 0°F for the metric illiterates, and Newfoundland if buried under about 4 feet or more of snow. Sure this is weather not climate but enough weather is climate.
Why does everybody seem to want to stop the ice from melting. Nothing can live in land covered with ice. Anyway I am sure carbon dioxide has nothing to do with it. We are just not trying hard enough to determine why the earth has gone through great periods of glaciation and then why it recovered, which is what is happening now. If you cannot explain repeated glaciations and past tropical forests in the arctic then blaming O2 is a useless exercise and it is not true.
Every "scientific" article on any subject will bring up global warming somehow. This is nothing but idiotic, or is it deliberate propaganda to reduce our prosperity, so that the really rich can buy up everything cheaply? AT YOUR EXPENSE TOO.
