First, science has shown that temperature goes up prior to an increase in CO2.

Second, CO2 has continued to increase over the last 10 years, yet, the temps are actually staying flat or going down. If there is a direct correlation between temp and co2, how can temps go down.

And, interestingly, there are actually more trees in America then there were several hundred years ago.

So, are you saying that nature has nothing to do with it?

I applaud your call for objective proof of man’s influence on global warming, but that herald has already been answered. Earth’s atmospheric CO2 concentrations have risen by 35% since the beginning of the industrial age, most significantly in the last 100 years. Since there hasn’t been any other source of increased greenhouse gases other than increased combustion from human activity, along with a loss of sequestration sinks (forest land), I believe man’s culpability is apparent.

You can argue that there have been some changes in the trends of global warming, such as upper ocean cooling, but that cooling trend you’ve cited is just a small fluctuation in the overall warming trend.
