🌍 Excited to announce our #EGU26 session: Understanding & Predicting the Impact of Climate Variability on Hydrological Regimes and Extremes 💧 (H2.4.12) 🗓️ Abstract deadline: 15 Jan 2026 (13:00 CET) 🔗 More info: meetingorganizer.copernicus.org/EGU26/sessio... #Hydrology #ClimateVariability #EGU26

This is a BIG DEAL! (excuse the Trumpian capitalisation but I've been a producer & consumer of hydrological datasets over a quarter of a century....how things have come along!) Both will be great assets to the community. Huge congratulations to the teams involved!

📣 Great news for UK hydrology! The UK Floods and Droughts Research Infrastructure (FDRI) has announced release of two new datasets: UK-Flow15 and CAMELS-GB v2. They provide access to sub-daily river flow and hydrometeorological data across 100s of UK catchments 🔗 fdri.org.uk/news/new-hyd... 1/ 🧪

Most river monitoring focuses on fixed points, missing how pollution moves downstream 🌊 UKCEH’s Alex O’Brien describes an approach combining multiple survey methods to reveal how pollutants mix and travel, which is key for better water quality management. 🔗 www.ceh.ac.uk/news-and-med... 🧪

A team from UKCEH, @metoffice.gov.uk, @uniofeastanglia.bsky.social and @ecmwf.int used satellite observations & advanced modelling to identify and investigate the causes of wildfires from Mar24-Feb25 fire season and the role played by climate & land use change. 🎥 Co-lead Dr Doug Kelley 2/

I'm a really big fan of these "storyline" approaches to uncertain forecasts – such a simple way to communicate quite a lot of detail and I think in a way that makes sense to many. Hope to see more of these on TV

After about one year in review, the dataset paper for the Caravan-GRDC extension was finally published. See: essd.copernicus.org/articles/17/... I am so happy that GRDC was open for this effort and made some of their data freely available through Caravan.

Great to see coverage of our first full @wasitusie.bsky.social study on RTE (and elsewhere). Kudos @clairebergin.bsky.social and Lionel swan as well as met Éireann colleagues and thanks as ever to @wwattribution.bsky.social for the hugely valuable collaboration www.rte.ie/news/ireland...

The people I work with are not stupid people and our climate predictions of 30 years ago of global warming have proved to be accurate. Just saying. www.bbc.co.uk/news/live/cp...

In a UN speech today, President Trump said that "all of these [climate] predictions were wrong". Back in 2019 I led a research effort to digitize old climate model projections and assess how well they did. Turns out they got future warming pretty spot on!

Just Launched 📢 The WMO’s 2024 State of Global Water Resources Report is now available! In 2024, the water cycle has become increasingly erratic and extreme, swinging between deluge and drought. This is the #StateOfWater. Read the report 🔗 https://bit.ly/469OBWU

📢 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

New analysis from @metoffice.gov.uk showing that the record-breaking hot UK summer of 2025 has been made much more likely by human-induced climate change and such a hot summer would be expected about once every 5 years in current climate. www.metoffice.gov.uk/about-us/new...

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

The UK has seen widespread drought this summer. But to what extent are UK droughts being impacted by climate change? In a timely piece up on @carbonbrief.org today, @ukceh.bsky.social hydrologists look at whether global warming is making UK droughts worse www.carbonbrief.org/guest-post-i...

Simple answer: high rainfall on average doesn’t mean there isn’t a problem when it stops raining.

Really disappointing new policy from NERC banning resubmissions of grant applications Many of us, including me, have won grants on resubmission, using the reviews to improve the application This is is neither fair nor productive www.ukri.org/councils/ner...

The discourse surrounding precipitation changes in a warming climate (both public discussion and even scientific one at times) is complicated by widespread conflation of changes in averages vs extremes (and also actual vs *potential* evaporation/evaporative demand). [Thread]

A quick read on the UK’s reservoir and river levels, and growing signs of some substantial rain this weekend.

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/
