Governor Newsom has finally called for a 15%voluntary reduction in water use in California.
Easy.
Here are some ideas for individuals.
1/n
If you water a garden 3 days a week, you'll save 33% of your outdoor water use by cutting it to 2 days.
Better yet, get rid of the lawn.
2/n
If you shower for 10 minutes, cut it to 7 and save 30% of your shower water. Better yet, get an efficient low-flow showerhead.
3/n
Replace a 6 gallon per flush toilet with a better performing 1.28 gpf toilet and save 80 of your toilet water. Flush 4 times a day instead of 5 and save 20%.
4/n
Farmers fallow 15% of your annual crops or put in drip or sprinklers or monitor soil moisture more accurately or change crop type.

So, a short thread about how much of the #globalwarming we're seeing is human-caused.
The short answer is ALL of it. Yes, all.
Why?
Here's the longer thread:
1/3
Many natural factors affect the #climate, including the output of the sun, volcanoes, changes (over many thousands of years) in Earth's orbit and tilt, the concentration of certain gases in the atmosphere.
Scientists understand these factors.
And here's the thing:
2/3
If humans weren't added heat-trapping gases, all these natural influences would be causing the Earth to very slightly COOL.
Therefore, ALL of the dramatic, fast warming we're seeing is due to human emissions of greenhouse gases.
That's it.

Wow. Under the radar, #climate deniers who have taken over the WH Office of Science and Technology Policy have published a series of "Briefs" claiming, falsely, to present "current state-of-the-science" on #climate. These essays are grotesque disinformation & pseudoscience.
A short thread about the recent claims by some "economists" & #climate skeptics that an 8°C rise in temperature would only cut GDP by 4%:
First, it's complete nonsense. That large a temperature rise would destroy the Arctic, flood every coastal city in the world, cripple (1/n)
global agriculture, worsen already severe hurricanes, & disrupt water supplies.
Second, if that's only "4%" of GDP, it's time to acknowledge that GDP is a totally useless measure of well being.
Third, a reminder that breaking your leg or crashing your car raises GDP. But... (2/n)
wiping out a species, destroying an ecosystem, killing 300,000 people in a pandemic has no effect on GDP (or the stock market).
Using traditional economics to understand the consequences of human-caused #climatechange will give you the wrong answers.

You think a #climatechange of just a couple of degrees is no big deal?
Around 12000 years ago, the planet abruptly cooled a couple of degrees, setting back humanity's social evolution for over a thousand years.
This cooling period, the Younger Dryas, delayed the transition in the Stone Age from hunter-gatherers to settled agriculture. When the planet warmed again at the beginning of the Holocene, homo sapiens began our slow climb to modern civilization. Now..
With humans changing the #climate by just a degree or so already, we're seeing massive fires, destruction of the Arctic, strengthening storms, species extinctions, environmental refugees. And much worse to come. Ironic...
1/5 A thread:
There is a severe and growing #climate and #water disaster in India.
Delhi just saw its highest ever June temperature of 48C. Churu, Rajasthan saw highs of 50.8C, making it the hottest place on earth.
2/5 Hundreds of Indian villages have evacuated as historic drought forces abandonment of homes in search of water. 80% of districts in Karnataka & 72% in Maharashtra are suffering drought & crop failure. Violent conflicts are growing between the two states over shared #water.
3/5 In Beed, India clean drinking #water is gone. There’s not have enough water to wash clothes, clean dishes, or flush toilets. Hospitals are filling up with people suffering from dehydration and water-related sickness from drinking contaminated water.
