Attribution of observed pan-Arctic extreme fire events to anthropogenic forcings
Over the past two decades, the pan-Arctic has experienced rapid climatic change, accompanied by an unprecedented rise in extreme wildfire activity. However, a systematic and regionally comprehensive assessment of the recent extreme fire events in the pan-Arctic and the role played by human emissions is still pending. In this study, we apply a probability-based extreme event attribution framework to evaluate the role of anthropogenic forcings in e…
The future of hot and dry events in the breadbasket regions of maize
Heatwaves and dry spells can severely impact crop yields, making it crucial to understand the nature of these events to ensure food security in a changing climate. We use the Max Planck Institute Grand Ensemble to examine the occurrence of hot–dry extremes in key crop-producing regions known as ‘breadbasket regions’, either in single or multiple breadbasket regions simultaneously, focusing on the differences between 1.5 ∘ C and 2 ∘ C global warmi…
Sensitivity of Arctic marine heatwaves to half-a-degree increase in global warming: 10-Fold Frequency Increase and 15-Fold Extreme Intensity Likelihood
We utilize the 50-member MPI-ESM-LR Earth System model to investigate the projected changes in Arctic marine heatwaves’ (MHWs) characteristics caused by an additional 0.5 ∘ C increase in global warming, from 1.5 ∘ C to 2 ∘ C, with respect to pre-industrial levels. Our results indicate that this 0.5 ∘ C increase in global warming triggers an intensified reaction in both the Arctic’s mean sea surface temperature (SST) and variability. In a 2 ∘ C wa…
Oceanic Rossby waves drive inter-annual predictability of net primary production in the central tropical Pacific
In the Pacific Ocean, off-equatorial Rossby waves (RWs), initiated by atmosphere-ocean interaction, modulate the inter-annual variability of the thermocline. In this study, we explore the resulting potential gain in predictability of central tropical Pacific primary production, which in this region strongly depends on the supply of macronutrients from below the thermocline. We use a decadal prediction system based on the Max Planck Institute Eart…
Improving seasonal predictions of meteorological drought by conditioning on Enso states
Useful hindcast skill of meteorological drought, assessed with the 3-month standardized precipitation index (SPI 3 M ), has been so far limited to one lead month (time horizon of the prediction). Here, we quadruple that lead time by demonstrating useful skill up to lead month 4. To obtain useful hindcast skill of meteorological drought at these long lead times, we exploit well-known El Niño-Southern Oscillation (ENSO)–precipitation teleconnection…
Preserving the coupled atmosphere–ocean feedback in initializations of decadal climate predictions
On interannual to decadal time scales, memory in the Earth's climate system resides to a large extent in the slowly varying heat content of the ocean, which responds to fast atmospheric variability and in turn sets the frame for large‐scale atmospheric circulation patterns. This large‐scale coupled atmosphere–ocean feedback is generally well represented in today's Earth system models. This may fundamentally change when data assimilation is used t…
