Here's the problem: While it is illustrated that CO2 is being produced at an ever-increasing rate and this could be a cause for concern, in terms of solutions the only thing we are seeing is a reduction of human activity. You must understand that the history of scientific achievement has been to increase the potential population density of man on this planet. We must ASSUME we can stop burning fossil fuels, but in the meantime we must improve the condition of man on this planet. Nuclear power!

There's NO WAY you are stupid, so what you are doing you are doing by INTENTION... and that makes you CULPABLE. Where is the MOST important PRIORITY problem of deforestation? Nothing you talk about will make any difference if we do not fix the rainforests. ALL YOUR CO2 doom will still happen if we do not fix the rainforests. Deforestation is a NO-BRAINER and you ARE part of the end. Please message me and let me know just WHY you aren't foremost on the case of fixing the forests? Mall

on 3) You are focused on industry emission. I was in England when the UN report came out and their news said that CH4 from growing numbers of cattle and excess fertilization was of similar impact to CO2. The more PC US TV ignored that aspect. It was enough of a worry in the UK that they are studying how to change the digestive process in cattle by changing the intestinal bacteria. Highlights the need for study and global solutions not just "perceived wisdom" like what led to corn ethanol.

1) Worldwide jungle and swamp, with significantly higher oceans. We can tell this from the fossil record. 2) The 'lag' you refer to is addressed in later videos. It's actually easily explained. 3) He mentions methane later in this very video. Although it's a stronger GHG by volume, we're not emitting as much, and when you calculate the relevant forcings based on emissions, CO2 currently dwarfs CH4. There are "tipping points" (discussed in Scare Tactics) that may result in CH4 increasing, though.
