Summer 2024 featured unprecedented warmth in the European Arctic, causing melting of 1 % of the total ice volume on Svalbard. Bad news is that in 2100 and even in the optimistic SSP1-2.6 emission scenario, 50% of the future summers will be warmer than 2024. www.pnas.org/doi/10.1073/...
Fig. 4a of the paper. The caption of the paper: Projected temperature evolution until 2100. (A) shows JJA air temperature measured at Svalbard Airport (black) and corresponding downscaled statistics from CMIP6 multimodel ensembles for four different SSPs. The shaded regions mark the 5 to 95% CI for the respective SSP, and the solid lines show the ensemble means. The level of the observed value for 2024 is indicated by the horizontal dashed line, and the yellow horizontal bar indicates the mean value of the 1991–2020 climatology. Vertical bars indicate the time when the ensemble means reach the observed 2024 level.Fig. S3a of the paper.

CO₂ removal (CDR) deployments require materials and energy, which emit CO₂. That’s why we talk about net CDR. Even if CDR affects ecosystems, it’s likely minor compared to the significant negative impacts of climate change on ecosystems. So we should focus on the net ecosystem benefits of CDR.
A black-and-white cartoon shows a trolley approaching a junction where its track splits into two directions. A person stands next to a lever, which can switch the trolley from one track to another. On the left track (the default path), there are five dolphins labeled “Not removing CO₂ from the atmosphere.” On the right track, there is one dolphin labeled “Deploying CO₂ removal (CDR).” The drawing suggests that not taking action to remove CO₂ may result in greater harm (symbolized by the five dolphins), while deploying CO₂ removal may have its own risks or costs (symbolized by the single dolphin), but is the comparatively better choice.
