Human contribution to the current megadrought in the SW U.S. is 46%

As I have said feel free at any time to publish a paper refuting this data

 

And you have research data definitively proving this?

 

Oh! Dear! Seems that you do not know the difference between raw data and a published hypothesis

 

CA needs to finish building Governor Pat Brown's water infrastructure project that Governor Jerry Brown stopped in the 70's.

Half of CA's water runs into the ocean. The CA infrastructure project recognized that CA alternates between Drought and Flooding with the El Nino/La Nina cycle and the thinking was that flooding would be controlled, storing the water to be fed into the water system during drought, with all the water projects also generating cheap abundant hydroelectric power. Great idea, Great concept, until they stopped halfway through and now have twice the population that the current water infrastructure was built for.

Oh, and they can't spend any more on water infrastructure, heavens no, they have Bullet Trains and Green Boondoggles to spend on. These are supposed to cut down on CO2 and we are supposed to ignore all the CO2 released as the water starved state catches fire and burns every year.

CA doesn't count that CO2 production, cuz, reasons.​

While completing the CA water project would take care of CA's immediate needs, as growth continues in the Southwest, the next big project will be bringing a major water project down from the Snake River to Las Vegas, opening up the entire State of NV to farming and residential housing, with the Hoover Dam terminus making sure SoCal is well supplied.

We have all the water we need, we just have to determine to build the systems to direct it where we need it.

 

Don't know whatsupyourbutt. Notice all you have to add is either alarmist pap or denigration.

 

There's nothing in the thread title about models or projections of future drought.

 

Democrats need to pass a law banning droughts.

 

Already done.

Several More New Studies Show Drought Is Now Less Common And Severe Than Centuries, Millennia Ago

By Kenneth Richard on 14. June 2021

Scientists continue to publish new drought reconstructions indicating there were far more frequent and severe drought periods in the past several thousand years than anything observed in the modern period. A new study (Berg and McColl, 2021) indicates there have long been “qualitatively incorrect” estimates of the impact modern and future warming has on drought […]

 

Yes. Here it is.

You know Jack, if the Democrats had supported more dams and reservoirs, rather than go on tears to rip them down, I could feel sorry for Democrats.
https://www.popularmechanics.com/sc...e reservoir, the,would take about three years.

 

Jack, maybe it is time for the Democrats to learn about the Pacific Ocean.
They should learn there are trillions of gallons of water in the ocean.
Technology can be put into action to refill the reservoirs in the mountains.
As a by product of using the Ocean precious rare earths will be produced.

When Democrats in America insisted on ripping down our dams they emptied the reservoirs. Now they act surprised.

 

What do you want to bet that they do not want to build more dams. That they do not want to use ocean water treated to be suitable to drink. They have no solutions.

 

So why the hell does Biden want more Mexicans to move here? Why is he allowing non citizens from all over the world into the USA?

 

Well I left CA in 2019 to live in Idaho. We have a hell of a lot of water here and enjoy good water.

If we can ship oil in pipes from upper Canada to lower TX, we sure can ship water like that to parts of the USA.

 

Not researc not peer reviewed

 

Nah. We just need to outlaw new data centers that store the geometrically increasing number of "We are doomed!!!" internet posts. https://www.nbcnews.com/tech/intern...ities-push-back-against-data-centers-n1271344

 

So what is causing this drought? Can you show the science and not just what scientists "said"?

 

Once again you are posting before reading. The following were cited/quoted/linked in the NTZ post.

The megadrought is mostly natural but it has been augmented greatly by human activitites. Read the report.

Large contribution from anthropogenic warming to an emerging North American megadrought
Science 17 Apr 2020:

 

"Mostly natural".....I still see no proof that humans are causing it.

 

Yup. Or even open canals.

A big ass canal from the Snake to Las Vegas would solve Las Vegas and Southern CA's water scarcity while opening up the state of NV to housing, farming and industry.

​

 

The OP is about the SW U.S. and not what is happening in other parts of the U.S which may be getting wetter.

Increases in all greenhouse gases are driving global climate change. This is well understood science.

What would the "heat budget" look like if humans weren't increasing the atmospheric levels of many greenhouse gases?
The Earth's energy imbalance would average something like 0.0 +/- 0.1 watts per square meter on the average for the last 50 years
with no evidence of any global warming. Instead, the oceans are warming rapidly, the surface is warming, the troposphere is warming,
Arctic sea ice is melting, and the vast majority of glaciers are melting. The nights are warming faster than the days because of increased
levels of greenhouse gases.

What you don't seem to grasp is that tiny changes to the Earth's energy
budget, something even less than +0.10 watts per square meter over a
long period of time (a few thousand years or more), can cause huge
changes to the Earth's climate. Climate feedbacks contribute greatly
to those temperature swings observed in ice core data.

 

So, am I assume that you have read and understood the science in the report and are drawing an informed conclusion
after careful consideration of the evidence??

 

I kinda dismissed it when it compared today's supposed mega drought to ones during the Medieval era.....were they driving cars back then? Such silly nonsense backed up by computer model trends or nonscience.

 

"We use hydrological modeling . . . "
Yawn.
