To hear that the time frame has now been moved to 40 years still displays a total misunderstanding of how old the earth is and how long a time period is needed to obtain even a modicum of knowledge re climate change,as I have said on numerous occasions hundreds of years are the only reliable scale.By the time (pun intended) they figure it out man well may not exist as a species but his demise will have nothing to do with so called "man made warming"
