When it rains, it now rains more.
For those experiencing the flooding in south-west England, it is worth remembering that rainfall in winter has increased by about 25% overall.
And, the rainfall has also become more intense: when it rains, it now rains more, increasing the risk of flooding.

Very high sea-levels this morning at Newlyn in Cornwall, thanks to this storm coinciding with a (moderate) spring tide.

Since it's coming up again in the Discourse: GPS (GNSS) is a passive system and does not itself actually track anything. The satellites just shout out their own position & time.
Your device just listens to that, works out its position, and may store or transmit that data through a phone connection.

Incredible work from @ptfretwell.bsky.social, Hamish Pritchard, and the Bedmap team...!
So much depends on the topography beneath the Antarctic Ice Sheet, including the future of sea level rise across the planet - and this new work will really help us understand and prepare.

🌊🧪@bgc-argo.bsky.social Float of the Month. WMO 7900823 deployed nearly 80 south in the Ross Sea has done 2 years under ice. Here's the data plot (all data freely available @soccomproject.bsky.social). No bloom this year! Too much ice melt, no deep mixing, and no iron to feed plankton - IMO.
