Slowing emissions reductions means more financially crushing #climate change - was nothing learned from the pandemic? It’s the area under the curve that matters, in this case greenhouse gas emissions over time. www.bbc.co.uk/news/article...
EU proposes slowing down cuts to carbon emissions for businesses
Under the proposals, the EU plans to relax its emissions trading system to give companies more time to reduce their carbon output.

In the journey towards tipping points, aspects of the #climate system can become more volatile. Commentary by @alevermann.bsky.social in @nature.com argues that the impacts of increasing regional instability of ocean, ice & atmosphere have not so far been properly assessed: doi.org/10.1038/d415...
‘Climate free fall’: why the biggest risk to our economies is yet to be recognized
Increasing instability of the ocean, ice and atmosphere threatens farming, finance and society. We all need to wake up to that fact.

Hot, dry end to June in UK on top of a dry spring with dry soils in the south, low river flows in east Scotland & East Anglia and some depleted reservoirs/aquifers with increased pressure on water resources through the rest of summer unless it becomes unseasonably wet: nrfa.ceh.ac.uk/sites/defaul...
In some temporary, slightly good news before the El Niño gets going, the annual CO2 growth rate from last year has been relatvely low in 2026 so far compared with other years based on @noaa.gov Mauna Loa data: www.met.reading.ac.uk/~sgs02rpa/co...
Intensification of hot, dry periods is killing the UK’s trees and while adapted management and deep soil watering can help, the long term solution is of course limiting #climate change by more rapidly decoupling our society from fossil fuels: theconversation.com/heatwaves-wh...
Heatwaves: why British trees are shedding branches and dying
British trees struggle to survive as temperatures get higher, and many die.

Like the differing types of dangerous heat affecting the UK in May & June this year, #heatwaves over recent decades have involved contrasting synoptic drivers as shown in our @rmets.org paper led by Nedim Sladic written up from his MSc dissertation @unirdg-met.bsky.social: doi.org/10.1002/wea....
Contrasting the synoptic drivers of the UK heatwaves of 1976, 2003, 2018 and 2022
UK summer heatwaves are dictated by the polar jet stream position and sea surface temperature (SST) variability, affecting the Summer North Atlantic Oscillation (SNAO) index. The SNAO can determine a...

There's more energy arriving than leaving Earth due to rising greenhouse gas levels and this is warming #climate & this energy imbalance is growing - a new study led by Herve Douville uses an observed reconstruction to infer this trend will not reverse before the early 2040s: doi.org/10.1029/2025...

It was a dry April over much of the UK, particularly in the south & east and the @ukceh.bsky.social hydrological outlook indicates current below normal river flows in southern/central England are likely to persist into summer without significant rainall: nrfa.ceh.ac.uk/sites/defaul...
