Earth's future climate and its variability simulated at 9 km global resolution
Abstract. Earth's climate response to increasing greenhouse gas emissions occurs on a variety of spatial scales. To assess climate risks on regional scales and implement adaptation measures, policymak...

The high-resolution simulations show a substantial increase in regional information relative to the TCo319 experiment, especially over topographically complex terrain. Examples of enhanced regional information include changes in temperature, rainfall, winds, extreme events, tropical cyclones. 🧪

We used the coupled earth system model OpenIFS–FESOM2 with a 9 km atmospheric resolution and a 4–25 km ocean resolution. We conducted a control simulation and 4 coupled transient simulations for the 2000s, 2030s, 2060s, and 2090s. 🧪

We present a wind reconstruction based on marine diatoms preserved in an Antarctic Peninsula ice core, to reconstruct westerly winds across the Pacific sector of the Southern Ocean. The poleward shift and acceleration of the westerly winds is unprecedented.

Our simulations also show clear evidence that extremes of vector density and EIR increase in the future by almost 100%, suggesting that major malaria epidemic outbreaks will become much more likely.

We compute the Time Of Emergence of vector density and the infectious biting rate using 50 members of Community Earth System Model version 2 Large Ensemble simulations. This reveals that vector densit and EIR will rise significantly and permanently above the pre-industrial background variability.

The detected propagation pathways are found to provide prior knowledge for occurrences of downstream heatwaves that can be used for identifying precursor signals. Our results provide potential predictability of terrestrial heatwaves.

Evidence for preferred propagating terrestrial heatwave pathways due to Rossby wave activity - Nature Communications
This study shows that terrestrial heatwaves either propagate or remain stationary along preferred pathways, influenced by Rossby wave activity. The results provide potential for heatwave predictabilit...

We examined the spatial propagation of terrestrial heatwaves using a complex network algorithm, and find four preferred propagation pathways of terrestrial heatwaves. Along each preferred pathway, heatwaves evolve in two ways: propagating along the pathway or being stationary

Our results show that with every degree global warming the global mean area burned by fires each year will increase by 14%. This can have substantial effects on ecosystems, infrastructure and human health and livelihoods.
