You "RECONSTRUCTED" temperature chart is an absurd fallacy. The medieval warm period was obviously warmer than it was today - as shown by all the scientific evidence including tree rings, etc. Just take a look at the Vikings growing crops in Iceland during the time.
Yeah OK. Take it up with the seven different teams, using different methods, that came up with the numbers.
futurecurrents is living this AGW alarmist fantasy that everyone who is skeptical about global warming does not believe CO2 is not a GHG. FC apparently can not differentiate this from the reality of what we are telling him. 1) GHG regulates air temperature - not only increases it. 2) The amount of CO2 added by mankind is so minimal compared to the overall CO2. 3) There is no evidence that AGW is causing significantly increased global temperatures, increased ocean temperatures, raised ocean levels, increased severe weather, polar melting, or any other damage to the earth. AGW is not a threat to man's existence or our habitat; "climate change' is not something that we need to take urgent action on.
