"The most worrying possibility behind Earth’s [accelerating warming] is how the general nature of clouds may be changing in response to climbing temperatures. It’s a feedback loop that could potentially exacerbate warming and is one of the single biggest uncertainties in predicting future climate."

Global Warming Is Speeding Up and the World Is Feeling the Effects
Human-caused global warming has been increasing faster and faster since the 1970s.

Performance studies of thin gas gap Resistive Plate Chamber prototypes with low Global Warming Potential gases for the ANUBIS experiment
Resistive Plate Chambers (RPCs) have traditionally operated with high Global Warming Potential (GWP) gas mixtures, adding to the environmental footprint of large-scale physics experiments. In response, efforts are underway to explore environmentally friendly alternatives as a long-term solution and low-GWP as a feasible short- to medium-term replacement for standard RPC gases. This study tests a few mixtures in 50 cm $\times$ 50 cm, 1 mm single-gap High-Pressure Laminate (HPL) RPC prototypes, a…

More summer weather extremes in Europe likely as North Atlantic Oscillation intensifies under climate change
Due to global warming, the North Atlantic Oscillation, an atmospheric circulation pattern that strongly influences European weather, is becoming more extreme in the summer, according to a study published in Communications Earth & Environment.

Last week, our students learned how to conduct a proper evaluation for an NLP experiment. To this end, we introduced a small textcorpus with sentences about Joseph Fourier, who counts as one of the discoverers of the greenhouse effect, responsible for global warming.

Detection, attribution, and modeling of climate change: key open issues
The CMIP global climate models (GCMs) assess that nearly 100% of global surface warming observed between 1850-1900 and 2011-2020 is attributable to anthropogenic drivers like greenhouse gas emissions. These models also generate future climate projections based on shared socioeconomic pathways (SSPs), aiding in risk assessment and the development of costly Net-Zero climate mitigation strategies. Yet, the CMIP GCMs face significant scientific challenges in attributing and modeling climate change,…

New simulations show how much colder European winters would get if AMOC collapses
A pair of meteorologists in the Netherlands has used new simulations to show just how cold many of Europe's cities could get if the Atlantic Meridional Overturning Circulation (AMOC) were to collapse due to global warming. In their study, published in the journal Geophysical Research Letters, René van Westen and Michiel Baatsen developed a climate model based on a range of ocean temperature changes that could arise due to global warming.

Earth is heading for 2.7°C warming this century. We may avoid the worst climate scenarios – but the outlook is still dire
The world seems to have avoided truly catastrophic climate scenarios, and global emissions may be about to peak. But we’re by no means out of danger

Decadal sink-source shifts of forest aboveground carbon since 1988
As enduring carbon sinks, forest ecosystems are vital to the terrestrial carbon cycle and help moderate global warming. However, the long-term dynamics of aboveground carbon (AGC) in forests and their sink-source transitions remain highly uncertain, owing to changing disturbance regimes and inconsistencies in observations, data processing, and analysis methods. Here, we derive reliable, harmonized AGC stocks and fluxes in global forests from 1988 to 2021 at high spatial resolution by integratin…

Warming from cold pools: A pathway for mesoscale organization to alter Earth's radiation budget
Marine shallow cumulus clouds have long caused large uncertainty in climate projections. These clouds frequently organize into mesoscale (10-500 km) structures, through two processes that couple the clouds to shallow mesoscale circulations: (i) mesoscale moisture aggregation, and (ii) cold pools, driven locally from rain-evaporation. Since global climate models do not capture these mesoscale processes, while the degree of mesoscale organization is observed to correlate to shortwave cooling, it …

Irreversible glacier change and trough water for centuries after overshooting 1.5 °C - Nature Climate Change
How mountain glaciers will react to temporarily overshooting 1.5 °C of warming is poorly understood. Here the authors show irreversible global glacier loss for centuries after overshoot, implying long-term reductions in glacial water resources with amplified impacts in regions where glaciers regrow.
