It’s a bit technical but very thorough. Another comment below:
Highly informative, if scientifically complex, answers to the question why why and by how much the atmospheric CO2 (carbon dioxide) budget is increasing were contained in a lecture just given in London by Professor Murry Salby. The lecture has been very well captured on video, illustrated by comprehensive (and comprehensible) charts and graphs, and posted to YouTube. It runs to 1 hr 40 minutes, and is worthy every second of it. (We are hoping to be able to post in the near future, a layman-friendly summary of Professor Salby’s findings that very little of the atmospheric CO2 budget can be blamed on human activity).
