Are Greenhouse Gases Increasing & Is the Climate Warming?
I would certainly say that CO2 is increasing. I doubt whether water vapor is increasing. I suspect warming will cause methane to increase. Based on the Volstock (sp?) ice cores, they have a pretty good idea of historic CO2 concentrations and it is confirmed in other ways. To ascertain whether the climate is warming, first you need to provide a time interval. Are we talking the last 10 seconds, the last 10 days, the last 10 years, the last 10,000 years. For the last 10 years, maybe not. For the last hundred years, I would say we probably are. We are certainly warmer than 10,000 years ago. We are considerably cooler than 10 million years ago.
