In August, 267 weather monitoring stations across China reported historic temperatures.

Officials say that the harvest for the coming autumn will be way lower than anticipated.

The dry conditions have been around for more than 70 days in Jiangxi and the situation does not look good.
Reservoirs have dried to “dead pool” levels in Anhui province. In other words, the water levels are so low that they are unable to discharge water downstream.
To deal with the situation, some experts have proposed cloud seeding to divert water from elsewhere. As to whether this approach will help remedy the problem is a different discussion.
