Research Over Tibet Gives Climate Insight 106
An anonymous reader writes "NASA is reporting that researchers have discovered thunderstorms above Tibet offer a direct path for water vapor and chemicals to move from the lower atmosphere to the stratosphere. From the article: ' Learning how water vapor reaches the stratosphere can help improve climate prediction models. Similarly, understanding the pathways that ozone-depleting chemicals can take to reach the stratosphere is essential for understanding future threats to the ozone layer, which shields Earth from the sun's harmful ultraviolet rays.'"

Note that the resolution is pretty coarse (8x10 degrees) so that it still runs at a decent clip on your Mac/PC, and therefore Tibet gets 1 or 2 grid cells, that is about it.
We just had a request about removing the Tibetian plateau [columbia.edu] and the resulting effect on Earth climate.

Vertically we have 12 layers and I'm not sure what type of structures appear there... You can see hadley cells, ferrel cells (slightly), etc.
Higher res models ported to the GUI are in progress. If you'd like to run them without the GUI there are many out there... both at GISS/Columbia and other climate labs.

I encourage you to read NOAA's summary of recent research on the topic: http://www.aoml.noaa.gov/hrd/tcfaq/G3.html [noaa.gov]
If you still doubt it, there's a long list of articles published by scientists in reputable peer-reviewed journals in the meteorological community.

No need to buy a new engine, new car, or new anything. Simply grow a 100% compatible with gasoline fuel, right now.

People might think you to be confused or fooled by the propaganda that the effect of water vapor swamps that of the anthropogenic greenhouse gases, but again you can look that up.
Basic technique for looking anything up == find sites with footnotes and check them. Trolls and PR industry flacks just make things up, and don't have cites that can be checked. It's the simple way to tell science from bullshit. Kind of a smell test.
Science is hard, you know. No other civilization in the ten to hundred thousand years people lived on Earth managed to invent science. It's worth the effort.

This is a bit extreme; The climate has been perturbed a LOT in the past - such by phenomenal heating through asteroid strikes, and substantial cooling after 'supervolcano' eruptions (most recently, only a matter of tens of thousands of years ago), but has not boiled or frozen. The attractors for those states can be that near....
