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…
Disentangling regional climate change
While the influence of uniformly-distributed well-mixed greenhouse gas emissions on global warming is well-documented and robustly attributed through multiple lines of evidence, regional attribution remains more challenging and dependent on the performance and resolution of climate models. This study investigates the extent to which observed regional temperature trends are attributable to global-scale anthropogenic factors, mainly the direct effe…
Attribution of extremes to greenhouse gas-induced changes in regional climate variability, distinct from changes in mean climate
Changes in regional climate variability serve as the initial indicators of positive climate feedback mechanisms, which are expected to intensify as greenhouse gas (GHG) emissions unfold. Therefore, it is crucial to examine the extent to which GHG-induced changes in regional climate variability, in isolation from changes in mean climate, contribute to the frequency of extreme weather events. In this study, I build upon the concept of the fraction …
Sensitivity of Arctic marine heatwaves to half-a-degree increase in global warming
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…
Emergent constraints on tropical atmospheric aridity—carbon feedbacks and the future of carbon sequestration
Carbon-climate feedbacks, which amplifies or attenuates atmospheric CO 2 from fossil fuel emissions, are one of the largest sources of uncertainty in climate projections. However, these feedbacks depend both on temperature and its coupling to water and energy cycles, especially in the tropics. We show that atmospheric aridity—quantified as vapor pressure deficit (VPD)—is a good proxy for this coupling. Tropical VPD is strongly correlated to the g…
