An infographic from Our World in Data titled "Global land use for food production" uses a series of stacked horizontal bar charts to visualize the distribution of Earth's surface and the disproportionate land requirements of livestock. The first bar shows Earth's surface is 71% ocean and 29% land (141 million km²); the land surface is then broken down into 76% habitable land, 10% glaciers, and 14% barren land. Of the habitable land, 45% (48 million km²) is used for agriculture, while 38% is forests and 13% is shrubland. The agricultural land bar reveals a major disparity: 80% (38 million km²) is dedicated to livestock (meat, dairy, and textiles) including grazing land and cropland for feed, while only 16% is used for crops for direct human consumption and 4% for non-food crops. Finally, two smaller bars at the bottom contrast this land use with nutritional output, showing that while livestock uses 80% of agricultural land, it only provides 17% of global calories and 38% of global protein, whereas plant-based foods provide 83% of calories and 62% of protein.

80% of agricultural land is used for livestock (and textiles), yet this huge land use provides only 17% of our calories and 38% of our protein.

16% of the land used for crops provides 83% of our calories and 62% of our protein. It's past time we rethink what we eat.

Analysis: UK newspaper editorial opposition to climate action overtakes support for first time

"All 98 editorials opposing climate action were in right-leaning titles, incl the Sun, Mail, Telegraph, Times & Express"

The utterly shameless & widely covered "report" out today, claiming net zero will "cost" £9tn is based on:

* Assuming free fossil-fuel energy, free petrol cars, free gas boilers, free gas power plants etc

AND

* Including climate damages in the "cost" of net zero

I kid you not, it is that stupid

British NIMBYism is truly a sight to behold.

“We are rejecting this solar farm, because one time I saw an electric vehicle on fire, which reminded me that decades ago a coal mining disaster killed lots of children”.

High-tech plans to save polar ice will fail, new research finds The plans could also unintentionally harm fragile polar ecosystems.

🪩 Stratospheric aerosol injections
🌊 Sea curtains
🧊 Ice management
💦 Water removal
🦠 Ocean fertilisation

None of these geoengineering fixes will mitigate effects of global warming in polar regions - instead they'll likely have serious unintended consequences

Antarctic glacier melt reveals remains of Briton who died in 1959 accident Dennis ‘Tink’ Bell fell into a crevasse at the age of 25 while working for the Falkland Islands Dependencies Survey The remains of a British man who died in an accident in Antarctica 66 years ago have been discovered in a melting glacier alongside ski poles, a pipe and a watch. Dennis “Tink” Bell fell into a crevasse in 1959 while working for the Falkland Islands Dependencies Survey (Fids), now the British Antarctic Survey (BAS), a few weeks after his 25th birthday. His body was not found until January, when a Polish expedition encountered bones near their base. Continue reading...

Claim: "Water vapor is a greenhouse gas!"
Reality: Yes, and there's more of it in a warmer atmosphere

-"CO2 is plant food!"
-pretty hard to eat when you're on fire

-"Climate has changed before!"
-We know, we told you that

-"Scientists don't know everything!"
- doesn't mean we know *nothing*

🇦🇶 Antarctica’s coastal zone is changing fast & it matters globally. A new #AntarcticRINGS review paper maps what we know, what we don’t & why it matters for sea-level rise. 🌊

Just one chart from the @metoffice.gov.uk State of the UK climate report published today. We get used to focusing on the record highs and how 35C has gone from being rare to routine. But just look at all those summers which never got to 30C even in my lifetime. It’s a different UK now.

NEW: Getting to net-zero will be much cheaper than thought for the UK – and unchecked global warming far more costly, says OBR
