Thirty spokes are joined in the wheel's hub.
The hole in the middle makes it useful.

...the value comes from what is there,
But the use comes from what is not there.

"Basically, it looks like the Earth released a gigantic fart of greenhouse gases into the atmosphere - and globally the Earth warmed by about 5C (9F).

Also happy to see they through in...

"Today's warming of the Arctic can, in all likelihood, be attributed to mankind's impact on the planet; but, as our data suggest, natural processes operating in the past have also resulted in a significant warming and cooling of the Arctic."

Awesome article dude!!! I had fun reading that one.

thanks, but after reading this. i dont understand how they can say that were a tipping point of run way greenhouse gas. if the temperatures use to be 9F hotter in the arctic

Yea I thought that didn't make too much sense but I was assuming they meant the rate of increase.

The Eocene is not only known for containing the warmest period during the Cenozoic, but it also marked the decline into an icehouse climate and the rapid expansion of the Antarctic ice sheet. The transition from a warming climate into a cooling climate began at ~49 million years ago. Isotopes of carbon and oxygen indicate a shift to a global cooling climate.[13] The cause of the cooling has been attributed to a significant decrease of >2000 ppm in atmospheric carbon dioxide concentrations.[8]
