And the original research paper:

Can’t get through the paywall, but generally the machine learning models are trained off data generated by the “old-fashioned” numerical weather models.
So future progress still depends on improving those models. But you can save some MWh and teraflops by running a cheaper ML version for a while.

It’s a devastating consequence 😔

Let's try not to mess it up too much, hey? 🌍 ❤️

This is why climate change is so scary - you don't need to trap much extra heat from the sun to make a massive difference to this planet.

The total amount of energy humans use in a year is just 0.6 Zettajoules. So if last year we had used every little bit of energy to heat up the ocean it would still take another 500 years to put that much heat into the ocean.

How much energy is that?
So much. Let's break it down a little.

Probably not. It's Zettajoules. 1 Zettajoule is 1000000000000000000000 Joules. (That's 21 zeros for anybody who lost count 🤯)
And the axis goes up to 300 Zettajoules.

The article has a beaut little graph showing changes in ocean heat content since 1955. Have a look at the y-axis. Recognise the units?

OK, so how fast is it warming?

From the article above: "Oceans cover more than 70% of Earth’s surface, and their warming is gravely concerning. It causes sea levels to rise, coral to bleach and Earth’s ice sheets to melt faster. Hotter oceans also makes weather on land more extreme"

We don't live in the ocean, so why should we care?

That’s about a 50% increase in the cost of petrol at the bowser here in Australia. ⛽️ ⬆️ 💵

Or, to put it another way,
USD283 per ton CO2 adds 65c per litre to the price of petrol.

The original post has since been deleted (probably for the best, tbh - it was not good)

"were associated with less climate benefits and greater costs than unprocessed foods but still offered substantial environmental, health, and nutritional benefits compared to animal products."

Again, from the *abstract* of the research article - you really don't have to dig to find this...
"In comparison, processed plant-based products such as veggie burgers, traditional meat replacements such as tempeh, and plant milks...

But the vegan alternatives are most definitely not "worse for the planet than meat and dairy" 🤦

The "just eat beans" bit is actually on point.
From the research article: "Unprocessed plant-based foods such as peas, soybeans, and beans performed best in our assessment across all domains."
