First of all can I make it clear - I'm completely convinced human activity, primarily through fossil fuel CO2 emissions over the last 200 years is causing global warming and that we have to at least try to do something to stem the trend. It's why we've got a Tesla, why my kids are going vegetarian and being much more careful about their consumer choices, as are myself and my wife - if to a lesser degree.
I also don't want to 'disrespect' the views of others - just to concentrate on the facts, which means science.
So here's the situation; a person I know is questioning the correlation between CO2 emissions and global warming. He isn't doesn't deny global warming is happening and doesn't deny CO2 is contributing to it but he's, lets say, wary, that there is too much of a mass stampede to try to fix things through the CO2 factor. He's also a chemical engineer, so he has a scientific background. For example, he has questioned the correlation between the rise in CO2 and the change in sea temperatures and suggests that a warming atmosphere has a smaller effect on ocean temperatures than is factored and alleges that scientists are not addressing this 'gap' in the data.
I am guessing that this point of view is not exclusive to him. So I am hoping that someone here can point me to some useful data to respond to his points.
For what it's worth, my point of view is that we can't just sit around pondering - if there is even a chance that CO2 is the primary cause of global warming and it can be mitigated, we need to try and not tomorrow but now. The benefits apart from the climate change issue include a cleaner and more pleasant (healthier air) environment and the switch to clean renewable energy creates a lot of new jobs everywhere.
