Why again, can't Gates fly Coach? Or First Class?
Why would anyone care? Seems like an unhealthy obsession. $9 billion is a lot of walking the talk to me.
10,000 years ago, the Continental Shelf was ocean-front property. Today it is 400' under water.
Good point!
10,000 years ago it was about 150 ppm CO
2 and it was so cold for so long nearly all the humans died.
See what a small change can make? Thanks for bringing that point to light.
CO2 levels are very close to all-time record lows.
No, the last half million years it's cycled between 175 and 300 ppm.
We're at 420ppm now (the graphic is a bit old).
Yes, it was a lot higher when the crust was molten.
As you can see, we're way above recent past cycles by a fair margin.
For perspective, Homo Sapiens emerged ~300,000 years ago.
I suspect that myth got propagated as it is common for graphs to
switch scales to millions of years which can throw perspective off. |

...have my doubts about accuracy and resolution of methods for temperature and gas concentration over geological time...
There is a lot of debate about that, but when you dig into it the difference in the numbers is actually fairly small and (not positive, but ) believe the IPCC factors them into the range of probability.
I also doubt that extrapolation of anything is correct. It assumes nothing happens outside the data range you have that takes over driving results.
True enough, but they've been doing this for decades now and their temperature predictions have ALWAYs fallen into the predicted range. See post
#32 for more. This is from one of their older reports, I added the red dots to show the actual measurements. The outer lines are their range of predicted accuracy, the inner lines are from various models.
Where people think they were wrong is from non-scientists that looked at the curved and printed all sorts of horror stories by extrapolating and without any real understanding of the science. Scientists at the time explained why that was wrong, but only sensational news gets air time.
@svetz...Watch the entire video i posted...I dare anyone to dispute the facts presented in the video...
I could watch the video and probably dispute everything even with my limited knowledge, but it wouldn't change anything so ultimately a waste of time.
I will say James Corbett is not a climate scientist, he does have a degree in
public policy (e.g., spinning things to sound good) and did the interview to push his book. Who said
look at the money trail? You can always find something on the internet that says anything you want. You have to wade through it with an open mind and look at the math as this thread attempts. But, if you have a specific concern, by all means bring it up.
Honestly, if all the major oil corporations admit to the IPCC being correct, that should shake your disbelief just a little.
