📢 New paper! Events like the winter 2023/24 floods are wetter with higher river flows due to climate change. A worst-case “storyline” shows flows could be even higher - anticipating UNSEEN extremes is vital for adaptation. 🔗: doi.org/10.1088/1748... @ukceh.bsky.social @climatecocentre.bsky.social

🌊 Latest UK Hydrological Outlook: Normal to below normal river flows likely in southern & eastern areas over the next 3 months, with low flows for the time of year persisting in some catchments. River flows in northwestern areas likely shifting towards normal to above normal by November. 🧵🧪 1/

With exceptionally dry conditions in many parts of the UK this year, hydrologists at UKCEH address the question of whether #globalwarming is increasing severity of #droughts in a guest post for @carbonbrief.org

Provisional statistics from the Met Office show that summer 2025 will ‘almost certainly’ be the warmest summer on record for the UK. It would move 2018 off the top spot and relegate 1976 out of the top five warmest summer in a series which dates back to 1884. 👉 www.metoffice.gov.uk/about-us/new...

The UK Hydrological Summary confirms heightened risk of drought impacts this summer — especially in eastern Britain. June was the warmest on record for England and 2nd warmest for the UK overall. Rainfall showed stark regional contrasts, with some areas seeing less than half of average. 🧵🧪 1/

📣 New paper: 💧💧💧 In July 2021 record breaking rainfall hit western Europe, we use ensemble boosting to explore different plausible storylines. These show it could have rained for longer, or over a larger area, or in a different place. Are we prepared? doi.org/10.1038/s432...

CANARI scientists from @ukceh.bsky.social have created UK river flow stripes. High flows are rising in the north/west and drought risk growing in parts of the south/east. Adaptation is needed to reduce impacts from swings between wet/dry. 🔗 climatelabbook.substack.com/p/visualisin... (4/4)

As we seem to, yet again, be talking about the hot UK summer of 1976, a reminder that the UK is not the world. Yes, it was hot that summer over our small region, but the bigger picture tells a different story. And, we've had hotter UK summers since.

UK Hydrological Summary for May: Recent rainfall brought some respite but summer began with depleted river flows, groundwater levels & reservoir stocks. Increases risk of further dry weather impacts, with climbing evaporation rates limiting rainfall effectiveness 🔗 nrfa.ceh.ac.uk/sites/defaul...

New CANARI research reveals predictability for UK summer droughts up to 1.5 years in advance 🏜️ Find out more in the paper published in Nature Communications Earth & Environment, led by @amulyachevuturi.bsky.social: www.nature.com/articles/s43...

The Telegraph is now having to publish so many corrections to articles where it attempts to find *any angle whatsoever* to attack net-zero polices that it makes sense to start tracking them here. These are the ones published since Labour won the election. "We are happy to correct the record."

UK Hydrological Outlook for May-July ☀️🌈 River flows likely to be below normal across most of UK, with potential for current low to exceptionally low flows persisting in some catchments. Flows in western Scotland and Northern Ireland are likely to be in normal range. 🔗 hydoutuk.net 💧 1/

This Spring (March-April-May) may end up being the driest on record for the UK. This would also make it the driest of any season in a dataset that goes back to 1836. Spring in 1852 currently holds the record for driest season at 100.7 mm averaged across the UK. www.bbc.co.uk/weather/arti...

87 years ago. In April 1938, Guy Callendar published the first evidence from thermometer observations that the world’s land areas were warming. He also linked the observed warming to the increase in atmospheric CO₂ from burning coal. 87 years ago. rmets.onlinelibrary.wiley.com/doi/abs/10.1...

☀️ The dry, warm weather in March and early April in much of the UK led to noticeably dry ground and river flows lower than usual - but recent rainfall has provided some relief. Our hydrologists have been assessing the impact on water resources ➡️ tinyurl.com/Apr25hydro #weather #WaterResources

💧Latest Hydrological Summary shows: -Below-average March rainfall in all areas of UK after dry winter -Many rivers in N & W have exceptionally low flows -Record low March groundwater levels in N Ireland, Scotland, Wales 🔎https://nrfa.ceh.ac.uk/sites/default/files/2025-04/HS_202503.pdf
