Open access notables Projected increase in the frequency of extremely active Atlantic hurricane seasons, Lopez et al., Science Advances: Future changes to the year-to-year swings between active and inactive North Atlantic tropical cyclone (TC) seasons have received little attention, yet may have great societal implications in areas prone to hurricane landfalls. This work investigates past and future changes in North Atlantic TC activity, focusing on interannual variability and evaluating the contributions from anthropogenic forcing. We show that interannual variability of Atlantic TC activity has already increased, evidenced by an increase in the occurrence of both extremely active and inactive

This is a re-post from the Climate Brink The world is emitting over 40 gigatons of CO2 per year, contributing to an accelerating warming of the planet. The world needs to cut emissions rapidly to be remotely on track to meet our Paris Agreement goals of limiting warming to well-below 2C, and we should be spending the vast majority (>95%) of our resources today on reducing emissions. But once we get close to zero emissions, we will need to rely on an increasing amount of carbon dioxide removal (CDR) to stabilize temperatures. As I discussed in 

This is a re-post from Yale Climate Connections Governments around the world face a conundrum. Virtually none are on track to meet their Paris climate commitments. That includes the United States, which committed to cut its emissions at least 50% below 2005 levels by 2030 but is only on track for 32-43% cuts by 2030 based on current policies. And many of those policies, like the clean energy incentives passed in the Inflation Reduction Act – the landmark 2022 climate law – could be rolled back by the incoming Republican administration and Congress, leaving the U.S. even further short of its climate targets.

A listing of 33 news and opinion articles we found interesting and shared on social media during the past week: Sun, November 10, 2024 thru Sat, November 16, 2024. Story of the week Our Story of the Week is completely "meta" (no, not that Meta). It's about our exploring how to improve the utility of the feature you're reading right now. Sharp-eyed or possibly even distracted regular readers of our weekly climate news roundup will have noticed some distinct differences in the prior two editions to this latest, compared with the past 634 releases.  Typically our weekly listing of news and analysis centered on climate change has been displayed in chronological order, more-or-less following the sequence of original article publication dates. This is a perspective that sometimes affords readers a sense of the development of particlarly prominent stories, a useful view of major de

Open access notables Microbial solutions must be deployed against climate catastrophe, Peixoto et al., Nature Communications [comment]: The climate crisis is escalating. A multitude of microbe-based solutions have been proposed, and these technologies hold great promise and could be deployed along with other climate mitigation strategies. However, these solutions have not been deployed effectively at scale. To reverse this inaction, collaborators across different sectors are needed — from industry, funders and policymakers — to coordinate their widespread deployment with the goal of avoiding climate catastrophe. Thi

In April 2024 we announced the (renewed) collaboration between Gigafact and Skeptical Science to create fact briefs, short but credibly sourced summaries that offer “yes/no” answers in response to claims found online. Our initial plan had been to publish one fact brief per week on Saturdays but - as happens with many good plans - this turned out to be a somewhat too ambitious target for the project. We therefore took it more solwly and while we sometimes managed to publish a fact brief on consecutive Saturdays, the production rate turned out to be one fact brief every other week on average. Regardless of that, we published fact brief #20 on November 9 and thought that this little milestone might make for a good reason to write a short blog post about this project.

This is a re-post from The Climate Brink, and an excerpt from a much more detailed State of the Climate Q3 2024 report that I published over at Carbon Brief today. See that for more details on climate model/observation comparisons, sea ice extent, and other climate variables. The warmest year on record In my latest quarterly state of the climate assessment over at Carbon Brief, I analysed records from five different research groups that report global surface temperature records: NASA&rsquo

A listing of 33 news and opinion articles we found interesting and shared on social media during the past week: Sun, November 3, 2024 thru Sat, November 9, 2024. Summary of this week's topics We asked Google's Gemini again for help categorizing the articles we shared during the week, but it couldn't do it this time around. So, we tried with OpenAI's ChatGPT instead, which is why the format is different compared to last week's. Now that we have two different versions of generated summaries, we'd like to know which format you prefer, so please let us know in the comments!

Skeptical Science is partnering with Gigafact to produce fact briefs — bite-sized fact checks of trending claims. This fact brief was written by Sue Bin Park from the Gigafact team in collaboration with members from our team. You can submit claims you think need checking via the tipline. Is there an expert consensus on human-caused global warming? A number of peer-reviewed studies found nearly all climate scientists agree carbon dioxide from human activities is warming the planet by making it more difficult for heat to escape the atmosphere.

Open access notables Anthropogenic warming has ushered in an era of temperature-dominated droughts in the western United States, Zhuang et al., Science Advances: Historically, meteorological drought in the western United States (WUS) has been driven primarily by precipitation deficits. However, our observational analysis shows that, since around 2000, rising surface temperature and the resulting high evaporative demand have contributed more to drought severity (62%) and coverage (66%) over the WUS than precipitation deficit. This increase in evaporative demand during droughts, mostly attributable to anthropogenic warming according to analyses of both observations and climate model simulat
