    Abstract: Meeting the Paris Agreement’s climate objectives will require the world to achieve net-zero CO 2 emissions around or before mid-century. Nature-based climate solutions, which aim to preserve and enhance carbon storage in terrestrial or aquatic ecosystems, could be a potential contributor to net-zero emissions targets. However, there is a risk that successfully stored land carbon could be subsequently lost back to the atmosphere as a result of disturbances such as wildfire or deforestation. Here we quantify the climate effect of nature-based climate solutions in a scenario where land-based carbon storage is enhanced over the next several decades, and then returned to the atmosphere during the second half of this century. We show that temporary carbon sequestration has the potential to decrease the peak temperature increase, but only if implemented alongside an ambitious mitigation scenario where fossil fuel CO 2 emissions were also decreased to net-zero. We also show that non-CO 2 effects such as surface albedo decreases associated with reforestation could counter almost half of the climate effect of carbon sequestration. Our results suggest that there is climate benefit associated with temporary nature-based carbon storage, but only if implemented as a complement (and not an alternative) to ambitious fossil fuel CO 2 emissions reductions.

    Frequent pro-climate messaging does not predict pro-climate voting by United States legislators

    Abstract: Legislators who frequently advocate for climate action might be expected to cast more pro-climate votes, but pro-climate messaging alone may not predict actual voting behavior. We analyzed 401 539 tweets posted by 518 United States federal legislators over the 6 months prior to the 2020 election and identified 5350 of these as containing climate-relevant messaging. Of the 4881 tweets that we coded as promoting climate awareness or supporting action (‘pro-climate’), 92% were posted by Democratic legislators while all 138 tweets undermining climate awareness or opposing action (‘anti-climate’) were posted by Republicans. Constituent support for Congressional climate action was only weakly related to the rate of pro-climate tweeting by legislators. Overall, we found that increased pro-climate tweeting was not a significant predictor of pro-climate voting when controlling for party affiliation and constituent support for climate action. We conclude that climate-concerned voters would be best served by using party affiliation rather than climate-related messaging to judge the pro-climate voting intentions of United States legislators.

    Abstract: Outdoor skating is a valued and culturally important winter activity in Canada that is vulnerable to warming winter temperatures resulting from anthropogenic climate change. Changes to the outdoor skating season (OSS) due to climate change have been estimated from historical weather records using the occurrence of daily temperatures below a particular temperature threshold as a proxy for rink availability. However, research on the actual weather conditions needed for outdoor rinks to be maintained in reasonable condition is limited. In this study, we used historical weather data and daily reports on outdoor rinks in Montréal to identify which daily or multi-day temperature variable can best act as an indicator of outdoor ice rink availability. We evaluated a series of temperature variables using a logistic regression to predict the likelihood of open rinks during each day of the season. Using AIC scores to select the best model, we found that the mean of the preceding six-day maximum temperature was the best predictor of skating availability. Using this temperature predictor, we then projected changes in the duration of the future OSS in Montréal based on global climate model data, downscaled to the island of Montréal using the MarkSim Weather Generator. Our results showed that the mean OSS duration in Montréal would range from a 15% to a 〉 75% decline by 2090 depending on which future emissions scenario we follow. In a scenario that limits global temperature rise to below 2.0 °C (RCP 2.6), we projected a 41 day mean OSS duration at the end of this century. By contrast, under a business-as-usual emissions pathway (RCP 8.5), the average length of the OSS in Montréal could decline to only 11 days per year. Our results suggest that very ambitious climate change mitigation will be required to preserve outdoor skating in Montréal in the face of ongoing global climate change.
