At AWI, we contribute to the EU #DestinationEarth (#DestinE) initiative with storyline simulations and more. These storylines explore how extreme weather events – like the 2019 Paris heatwave or the 2024 European floods – could unfold in different climate scenarios, like in a 2ΒΊC warmer world.

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:
	β€’	Red represents dust (du), primarily visible over arid regions like the Sahara Desert and extending into the Atlantic.
	β€’	Blue indicates sea salt (ss), prominent over the oceans, particularly in stormy regions.
	β€’	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.
	β€’	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 albedoβ€”driven by declining low-cloud coverβ€”helps explain the unexplained portion of the warming beyond (expected) anthropogenic influences and El NiΓ±o.

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.

🚨 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?

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 (48.5-49Β°N and 2.0-3.0Β°E). This comparison highlights the varying intensity of the heatwave across different climates.

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 +2Β°C future. Check out our work led by Amal John: essopenarchive.org/users/852952...
