How will interaction with geophysical data evolve in the age of AI? 🤖🌍

In our latest preprint, we explore this question - not just conceptually, but with a hands-on prototype using the PANGAEA archive. Check it out!

🌍🌐 What if we could replay recent extreme weather under different climate conditions? With storyline simulations in the EU’s #DestinE initiative, scientists are reconstructing past, present, and future extreme weather to help us adapt to climate change.

Preprint summarizing the first results from the nextGEMS project, which prepares several coupled models to run at kilometer scale: egusphere.copernicus.org/preprints/20... 🧪
This image is a global visualization of aerosol distributions on September 5, 2020, at 00:00 UTC. It represents different types of aerosols using a color-coded scheme: • Red represents dust (du), primarily visible over arid regions like the Sahara Desert and extending into the Atlantic. • Blue indicates sea salt (ss), prominent over the oceans, particularly in stormy regions. • Green signifies carbonaceous aerosol (ca), which is associated with biomass burning and pollution, visible over regions like the Amazon, Central Africa, and parts of Southeast Asia. • Yellow shows sulfuric aerosol (su), often linked to volcanic emissions and industrial activity. The image is overlaid on a world map with latitude and longitude markers. The transparency of the colors varies to indicate concentration levels, with fully transparent areas representing minimal aerosol presence and fully opaque areas representing maximum concentrations. The right-hand legend provides a scale for interpreting the aerosol concentrations in milligrams per square meter.

In 2023, global mean temperature approached 1.5K above pre-industrial levels, with our study suggesting that a record-low planetary albedo—driven by declining low-cloud cover—helps explain the unexplained portion of the warming beyond (expected) anthropogenic influences and El Niño.

🚨 Freshwater bottleneck in the Arctic? 🌊
A Beaufort Gyre freshwater release shifts to a buffer zone near Greenland, delaying Arctic freshwater flow to the North Atlantic. Implications for ocean stratification, salinity anomalies, & AMOC?

Arctic freshwater anomaly transiting to the North Atlantic delayed within a buffer zone - Nature Geoscience
Freshwater being released from the Beaufort Gyre is accumulating in an Arctic Ocean buffer zone before it can reach the North Atlantic, according to an analysis of satellite observation and modelling.

The storyline approach isn’t new, but for the first time, we’re using it with 10km resolution! 🌍 See how extreme events might have looked in the past, without climate change, and how they could unfold in a +2°C future. Check out our work led by Amal John: essopenarchive.org/users/852952...
The maximum 2m-temperature during the peak heatwave period (July 25, 2019) over France for the different storyline experiments (top panels: a, b, c). The bottom chart illustrates the hourly maximum 2m-temperature from the different experiments for the Paris region inside the black dotted box (48.5-49°N and 2.0-3.0°E). This comparison highlights the varying intensity of the heatwave across different climates.

A paper in Communications Earth & Environment presents an automated system that unveils the climate change signal of the day in near-real-time storylines. The system suggests that storm Boris deposited about 9% more rain due to human-induced warming. go.nature.com/3ClX3Wq 🧪
This is figure 1, which shows the storylines of the extreme rainfall of the September 2024 storm Boris.
