25% of the world's mud ?

"Between them, these rivers carry 25% of the world's mud."

Can anybody confirm or give a source for this percentage? Lawrence Lavigne 23:04, May 6, 2005 (UTC)

[1] gives the same figure- I don't think that's where I got it from in the first place, but perhaps we're using the same ultimate source. Mark¹ 02:05, 9 May 2005 (UTC)

If you could simply assume the region is in equilibrium with erosion equalling uplift, you could calculate the annual production of mud as uplift times area. For example 1 cm of uplift over 1 million square km should produce ten billion cubic meters or ten cubic kilometers of mud.

A few complications:

1. Some fraction of the mass is actually soluble and ends up as salts etc. rather than sediment
2. There may be net uplift. Are parts of the plateau and mountains actually going higher?
3. A substantial part of the plateau has no outlet to the sea. That fraction of sediments ends up in the lowest parts of local Endorheic basins rather than washing down into countries on the periphery (India, Burma, China, etc.) and ultimately into oceans. Altough it's still mud, implications are different. LADave (talk) 19:06, 8 April 2011 (UTC)

Area units

The figure "1,000 to 2,500 kilometers" appears to be a length or a width. It should be written as an area, my guess would be around several million km^2. Could someone fix this??

Geology and Origin

Perhaps a summary paragraph on the geological origin of this pecular land form? See Geography of Tibet & Geology of the Himalaya. WBardwin (talk) 05:32, 4 September 2009 (UTC)

Role in monsoons?

The section "Role in Monsoon Regime" does not actually explain the Tibetan Plateau's role in creating monsoons over South Asia. It explains how monsoons form in general, but stops short of explaining how and why the plateau's geography causes monsoons. Can someone fix this? Jaybird vt (talk) 16:46, 23 September 2009 (UTC)

Influence on Ice Age climate

It is a matter of debate to what extent the Tibetan Plateau was ice covered. Due to rainshadow the ice may have been limited to the Himalayas. Anyway, I find it misleading to say that there was no monsoon during the Ice Ages. To me it makes it sound like the Indian subcontinent did not get any yearly rain at all. According to this map most of the subcontinent was steppe at the peak of the last Ice Age. (An easier to read version can be found here.) In the eastern part of present-day India there was an area with tropical dry woodland. This area must have got sufficient amounts of rain almost every year for the trees to survive. Southeast Asia was about half covered in forest showing there was monsoon further east. However, this can be explained by present-day eastern China warming up during the summer months.

I also want to point out that the Sahara desert was actually larger during the Ice Ages. The so called Wet Sahara phases occurred at the beginning of interglacials. On the other hand West Africa was not as dry as Central or East Africa. So changed wind patterns may have increased rainfall there during the Ice Ages.

Archeological evidence?

Please remove the 30,000-year sentence in the Human History section. Ask a Tibetan, not those who invaded and continue to occupy the Sovereign Nation of Tibet. The Dalai Lama puts the civilized date to 40,000 years ago. Before that, the nomadic tribes were too sparsely populated to get together in a civilized manner.
The indigenous folks have developed crops that are well-suited to the high elevation. It was the invaders as part of their continued acts of genocide who forced farmers to plant lower-elevation crops that led to tens of thousands of people dying of starvation. It is the Chinese invaders who then falsely concluded that "crops, which are unsuitable", livestock vs farming. Communist party propaganda trolls will surely petition to have this criticism deleted.

"as much as 15 °C (27 °F) cooler"?

The article reads:

"and daytime temperatures ranging from around 7 °C (45 °F) in winter to 24 °C (75 °F) in summer – though nights are as much as 15 °C (27 °F) cooler" 

"as much as 15 °C (27 °F) cooler"? Does it mean that usually they are less cool, or even not cooler at all? Does it mean that the lowest night-time temperatures are: 7-15 = -8°C in winter , and 24-15 = 9°C in summer? 85.193.252.19 (talk) 19:40, 21 October 2021 (UTC)

I don't seem to be able find that text in the current version of the article. Mikenorton (talk) 20:44, 21 October 2021 (UTC)

Oops, sorry. It was in Geography of Tibet. 85.193.252.19 (talk) 00:04, 22 October 2021 (UTC)
