Turns out, desert dust particles mask the aerosol effects on clouds (e.g. cloud life time or cloud albedo/brightness).

Joint work from Bar-Ilan University and @meteoleipzig.bsky.social led by Goutam Choudhury.

Reaching net zero by 2050 is often framed as a cost burden.

The UK Climate Change Committee’s latest analysis suggests the opposite.

The real risk is fossil fuel dependency.

The EU’s agri-food system must prepare for rising climate risks and accelerate emission reductions, according to the @esabcc.bsky.social.

A new report, co-authored by Imperial's Prof @joerirogelj.bsky.social, highlights rising climate risks to Europe's food system about provides 6 recommendations 🧵

It’s astounding and encouraging that the Met Office put out these long scientific explanations of how our world works. We need more science in the world like this. 👏

Climate change is speeding up — the pace nearly doubled in ten years Earth is now warming at a rate of around 0.35 ºC per decade, fresh analysis finds.

Here is what the journal Nature has to say about our paper on the increasing rate of #globalwarming:

Scientists up in arms as flying lab has its wings clipped Faam, the airborne laboratory deployed after the eruption of an Icelandic volcano shut airspace in 2010, will be grounded after government funding was cut

The decision by @ukri.org to scrap the UK's flying atmospheric laboratory (FAAM) after spending >£40M on an upgrade & with zero consultation, is short sighted. FAAM has saved the UK economy more than it costs through responding to disasters.

Between 1992-2025, large areas of the grounding line of #Antarctic glaciers have retreated. The largest changes have occurred in W. Antarctica, where grounding lines have retreated 10-40+ km, driven by incursions of warm water masses along deep bathymetric troughs

Important results! Tyre abrasion increases various health risks. The catch: EVs are not going to change that! Speed restrictions and prioritisation of active modes of mobility do!

One week from now, #COMPEX will kick off in #Svalbard. #Polar5 from #AWI will be operated to observe clouds over sea ice and around the #AWIPEV research base in #NyAlesund and to perform #EarthCARE underflights. 🧪 #remotesensing #AC3

Occurrence of seeding multi-layer clouds in the Arctic from ground-based observations Abstract. Studies of Arctic clouds often focus on low-level single-layer clouds (SLCs). Here, we use combined observations of soundings and cloud radar during the MOSAiC, ACSE, and AO2018 research cru...

New paper out in ACP:

Ice-crystal seeding from higher clouds, which can induce glaciation of supercooled clouds in lower layers, occurs in about half to two thirds of the identified cold multi-layer cloud regimes during the MOSAiC campaign in the Arctic.

🌍 The earth’s green is increasing and its centre is moving north-east. Vegetational shift to the north is even stronger in the southern summer – surprising new facet of #globalgreening 🌱 Published in PNAS

Europe remains one of the economies most exposed to volatility in global energy markets.

The EU still depends on imported fossil fuels for close to 60% of its energy needs.

Among large economies, only Japan and South Korea have higher levels of energy import dependence.

My first paper had to be mailed to Stockholm, Sweden, and then mailed to reviewers around the world. Everything by mail! It was submitted, reviewed, revised, typeset, and published in 3 months. I feel bad for early-career scientists who can't find a single reviewer after 5 months. It's gotta change.

As I was made to wait 2.5 minutes to cross a road this morning, let's again do the maths simple.ghost.io/lets-do-the-...

For 23 million years, temperate Europe was dominated by a mosaic of woodland-grassland biomes, shaped by large herbivores.

Until human started eradicating the megafauna and closed-canopy forests took over.

Why are we observing a 'green backlash' when serious efforts to decarbonise have scarcely begun? I'm happy to share my working paper, 'The Political Consequences of Climate Ambition: Evidence from Australia', which analyses how voters respond prospectively to proposed climate policies. Brief 🧵:
