Ummm
Maybe the dams?
Maybe "increased severe weather events including drought"?

Why does NObody listen to the scientists?
They know exactly WTF is going on and have been talking about it for years.

But glad to hear it has attracted a little curiosity now that everybody's 24hr aircon is threatened.

(and you wonder why Greta and all the other bright bright kids are steaming angry)

Climate change in the Mekong River Basin

Lower Mekong Basin mean annual rainfall. Source MRC 2010.
Countries in the LMB are among the most vulnerable locations in the world with respect to climate change. While the future impact of climate change is difficult to forecast, projections for the Mekong River Basin for the next 20 to 30 years, based on a downgraded global climate model, are as follows:



Basin-wide temperature increase of 0.79°C, with greater increases in colder catchment areas in the north
Annual precipitation increase of 200 mm (a 13.5% rise)
Increase in dry-season precipitation in northern catchments and decrease in southern catchments
Total annual runoff increase of 21%
Increase in flooding in all parts of the Basin with the greatest impact on downstream catchments of the Mekong River
Climate change is expected to affect natural ecosystems and agriculture throughout the Mekong River Basin, thereby exacerbating the challenges of meeting the increasing demand for resources from growing populations (Hoanh et al. 2003).
