New dataviz: the UK is a tiny crowded land mass with incredible wealth. Land ownership is a source of power and land usage the subject of debate. We got very nerdy with this one, hope you enjoy https://t.co/i3n0cjy7Eu

NYC is having the driest fall on record... only 0.01 inches of rain fell in October. There were 29 whole days with no rainfall, the second longest stretch in the city's history.

To have a chance against global warming, key economies and industries need to hit crucial emissions targets by 2030. They’re far off track.

Some shadow fleet tankers choose not to use DanPilot transit services to navigate the straits. Denmark’s worst ever oil spill in 2001 was the result of a ship collision and killed up to 20,000 birds. @sanne_wass

230 shadow fleet tankers have transported Russian crude oil through the Danish straits 741 times since the start of 2022. More than a third of the ships are beyond the age at which they’d often be sold for scrap

[Hayley Warren @hellococomo]

This 21-year old tanker is part of a growing, untraceable fleet that Russia has assembled to keep its oil flowing. They pass through Denmark’s narrow straits on a daily basis, when the impact of one spill could be felt for decades

🥵🏃 Among the most gruelling #Paris2024 events is likely to be the marathon, which starts at Paris City Hall, an area with a high density of zinc rooftops and lack of vegetation.

Amazing work by @hellococomo and @jwf825 ⤵️

How the Tories could lose a load of seats along the west Thames to the Lib Dems — including 140-year Conservative stronghold Henley — in part due to fury over sewage-infested waters

A race to map out smallholder farms across the world is underway, as EU importers need to attest goods aren't coming from deforestated lands, starting next year. These are the economies whose farmers are most exposed to #EUDR => https://t.co/egzwJsy6rQ @BBGVisualData

1) Happy Tuesday,

The UK Met Office says there are 10 sunspot clusters on the Earth-facing side of the big star. In the last 24 hours solar activity has been moderate and the US Space Weather Prediction Center said a G1 is possible later. #spaceweather

The largest geomagnetic storm since 2003 occurred last Friday, delivering rare views of the aurora to areas far from the Earth’s poles.

The solar storm affected power grids and more storms could be coming.
