Emerging #drought hotspots across Europe, southern Africa, northern South America + western North America based on new approach considering growing season soil moisture available to plants - @natureportfolio.nature.com study by Emily Black @unirdg-met.bsky.social: doi.org/10.1038/s415...

I’d wondered about burying trees to lock away carbon and assumed it’d be too slow but here’s a proposal to sink them in the Arctic Ocean (via @newscientist.com):

The @uniofreading.bsky.social has been a leading advocate for #climate education to better prepare young people for changing careers & society, as explained by our head of school Andrew Charlton-Perez OBE in this @uk.theconversation.com article:
theconversation.com/climate-educ...
Climate education proposals will prepare young people in England for changing careers and society
Ensuring that all young people develop strong climate and nature literacy will be essential for both personal resilience and national prosperity.

Fascinating to see the stark contrasts in space and time over our small but diverse country! Climate whiplash literature will certainly be assessed in the current @ipcc.bsky.social cycle

Latest @ukceh.bsky.social UK hydrological summary for November 2025 - very wet with shift from #drought to #flood concerns and consistent with an expected more variable and extreme water cycle in a warming #climate:

We gathered for a festive feed to celebrate our 39 picks by 75 volunteers working a gruelling 942 volunteer-hours to collect 563 small bags + 375 big bags of litter from across Caversham in 2025. As usual Ken wins🥇for the most picks (35)! Thanks to @dofe.org volunteers for their help #litterpickers

No. But at the top of our new large water tank is the computer that assesses various in/out temperatures & weather conditions to fine tune things. There’s a survey before install to assess heat loss from each room so they know if to install bigger radiators and they’d answer these kinds of questions

Not noticed any issues? Our air to water heat pump is designed to work effectively and without issue down to -10C snd below and has inbuilt frost settings so shouldn’t be an issue in the UK, though regularly checking for debris or snow build up is also recommended.

As well as rapidly cutting CO2 emissions, tackling short-lived warming agents like methane & surface ozone pollution boosts action to limit #climate warming + counteracts warming from cleaning our air of harmful aerosol particles that have robbed us of sunlight: theconversation.com/the-fast-fix...
