Megadrought

Recommended Posts

A new study of water conditions in Western US from 800 to 2018 identifies 40 major droughts of which 4 qualify for the title megadrought.

The most severe was 1575 to 1703, showing these last a significant length of time in human terms, importatant as we have been in one since 2000.

The droughts are attributed to normal climatic cycles, but a connection to climate change is also discussed.

The pictures look scary. Scientists said that the megadrought has to be related to the La Nina weather phenomenon. Now because of the megadrought, lakes have been shrunk drastically and fire can start easily. I hope there are something that we can do about this.

We can prepare for the worst, or stop doing shit to the planet, and hope for the best.

Obviously, the best solution is to take care of the climate properly-- but things can be done.  For example, here in northern Nevada we had a major reservoir go dry (<5% capacity) a couple of years ago.  As a solution a wintertime cloud seeding project was started focused on the mountain systems that feed the local rivers.   By cloud seeding at strategic times, the project built the snow pack to 150% of the historic norm, and the spring runoff has refilled the reservoir without any deleterious flooding.

Thank you for that reply and information. +1

I see that if any, the prevailing winds are from the North in the vicinity of 40o N and there is a slight winter maximum to average rainfall.

Since water dropped on your mountains cannot be carried and dropped elsewhere, can you say if there has been any rain shadow effect say to the South or in Utah ?
