The #storm that hit #dubai today had so much water in it that the sky turned green.
What causes this?

It dropped 1.5 years worth of #rain in a single day. #extremeweather

Yuanyang, Yunnan - a county famous for its rice terraces, reached 43.1C today

This is the first time China has experienced temperatures above 43C in April

The UAE is using salt flares to trigger rainfall from clouds passing overhead

Note: These do not use , the flares are as harmless as table salt.

I wonder if this technique could be used to refill the

💧 the is a really cool idea, literally. It's a way of using evaporating seawater to cool and humidify crops 🌱, which can drastically reduce the amount of fresh needed to support the in a desert .

As and scarcity increasingly challenges crop survival over the coming decades, carbon neutral seawater greenhouses will become much more common.

It looks like Vincennes, Indiana will have one of the best viewing locations in the US, with a mostly clear sky and 4 mins 6 seconds of .

Glaciers exposed to the are melting much faster than previously predicted. 🧊 ☀️

Melt underneath the in the 'grounding zone cavity' significantly increases the projections of glacier mass loss as these zones reduce the amount of resistance glaciers experience as they flow out into the sea.

The result is that past models underestimate the severity of rise over the coming decades

Why has the sea surface temperature ( ) increased so fast this past year and a half? Are models missing key factors?

The article provides a good overview of some of the compounding effects (SO2 aerosols, 25, vapour from the Hunga Tonga and El Nĩno), but is it enough to explain what’s happening? Either way, it’s an enormous amount of heat.

@Edelruth @dave it’s shocked a lot of people - the next 12 months will be really important in determining whether this represents a new regime that will require updated climate models

@russellt You're right about bitcoin and other proof of work based currencies, however this is no longer the case for Ethereum, the second largest crypto.

Ethereum upgraded from Proof of Work (energy intensive) to Proof of Stake (collateral intensive) in Sept 2022, so it now uses a negligible amount of energy when compared to , bitcoin, or video games

Superconductors have many applications, one of them being to enable long-distance power lines, dramatically reducing bills through improved transmission efficiency.

This is actually a pretty good explanation of the field in !

Particles that can interact with the Higgs field are resisted by it, and that extent of that resistance is what gives the a mass.

about 10 hours (GWh) of electricity is needed to train

as training for large AI models scales into the hour (TWh) range, responsible AI companies will need to fund the development of projects to help offset the massive emissions that would occur from drawing from the US electrical grid.

dave,
@dave@mastodon.solar avatar

@simon_brooke fair point, although training will likely continue to scale up in energy demand for many years to come

Models that require a terrawatt-hour to train, if connected to the grid would emit on the order of a quarter million tons of indirectly. AI companies will need to become clean energy companies.

@simon_brooke one future path may be to move data centers for training these large models into (as a distributed network of ) where they can draw from endless

Bottom-trawling destroys habitats and, by stirring up sediments, has shown this practice results in the release of enormous amounts of into the globally each year (about 0.8% of total). Models indicate that 55% of the CO2 from stirring up the sea floor ends up in the after nine years.

We need to scale back this destructive practice

It's important to keep CO2 from escaping the floor and to preserve these habitats

I just learned about the carbonmapper.org site which maps out #methane leaks around the globe using #satellite data 🌎🛰️

Methane is a potent #greenhouse gas (28x more potent than #CO2), and it needs to be flared off or otherwise mitigated.

This satellite #data has high enough resolution that you can clearly see the source in many cases. I just signed up for their mailing list.
