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. Are we heading into an ‘ice age’? The planet has been getting warmer since the Industrial Revolution, not colder. Historically, ice ages have followed changes in the Earth’s relationship to the sun. Natural cycles affect the tilt of

Open access notables An intensification of surface Earth’s energy imbalance since the late 20th century, Li et al., Communications Earth & Environment: Tracking the energy balance of the Earth system is a key method for studying the contribution of human activities to climate change. However, accurately estimating the surface energy balance has long been a challenge, primarily due to uncertainties that dwarf the energy flux changes induced and a lack of precise observational data at the surface. We have employed the Bayesian Model Averaging (BMA) method, integrating it with recent developments in surface solar radiation ob

According to the Programme for Monitoring of the Greenland Ice Sheet (PROMICE), the Greenland Ice Sheet has been losing mass continuously since 1996, with an accumulated loss since 1986 approaching 6,000 metric gigatons, or 6 trillion

A listing of 23 news and opinion articles we found interesting and shared on social media during the past week: Sun, December 8, 2024 thru Sat, December 14, 2024. Listing by Category Like last week's summary this one contains the list of articles twice: based on categories and based on publication date. Please feel free to let us know in the comments - if you haven't already - which one you prefer. Checking if we assigned the (most) relevant category is also appreciated. Thanks for your help with this! Climate change impacts New York Isn`t Ready to Fight More Wildfires  New York could see more frequent and destructive blazes, but the state doesn’t have enough forest rangers and firefighters

Open access notables: Regional Impacts Poorly Constrained by Climate Sensitivity, Swaminathan et al., Earth's Future: Climate risk assessments must account for a wide range of possible futures, so scientists often use simulations made by numerous global climate models to explore potential changes in regional climates and their impacts. Some of the latest-generation models have high effective climate sensitivities (EffCS). It has been argued these “hot” models are unrealistic and should therefore be excluded from analyses of climate change impacts. Whether this would improve regional impact assessments, or make them worse, is unclear. Here we show there is no uni

This is a re-post from The Climate Brink As I noted a few months back, despite the end of El Niño conditions in May, global temperatures have remained worryingly elevated. This raises the question of whether this reflects unusual El Niño behavior, or a more persistent change in the underlying climate forcings or feedbacks. At the time I did a fairly basic analysis comparing the current 2023/2024 El Niño event to the two other recent strong El Niño events – those in 1997/1998 and 2015/2016. However, an “N” of two does not tell us all that much, and the approach was overly simplified in not actually accounting for differing El Niño timing or accurately normalizing for the warming between El N

This is a re-post from Yale Climate Connections Climate pollution caused by burning fossil fuels hit a record 37.4 billion metric tons in 2024, marking a 0.8% rise from the previous year – and dashing hopes that a peak in global emissions might occur thi

A listing of 24 news and opinion articles we found interesting and shared on social media during the past week: Sun, December 1, 2024 thru Sat, December 7, 2024. Alternative listing prototype Instead of a "Story of the Week" we added a listing by assigned category, so this installment will have the same list of articles twice, first by category and then by publication date. Please let us know in the comments which format you prefer, if the manually assigned categories actually fit the articles and if additional categories might make sense without getting too fine grained. To keep things simple, an article can only be assigned to one category. Climate change impacts Doomsday Glacier collapse! Time for MORE human intervention??   by Dave Borlace, "Just have a

In March, John Cook met with Adam Ford from Science, Technology & the Future to talk about his work researching misinformation and how to counter it. The interview - published on October 10 - explored the complex and evolving landscape of climate misinformation, covering a range of topics including the different types of misinformation, the role of social media and AI in spreading and combating it, the psychological barriers that prevent people from accepting climate science, and the importance of communicating effectively about climate change. Key takeaways include: The nature of climate misinformation: Misinformation takes many forms, including outright denial of climate science, attacks on climate scientists and solutions, and promotion of conspiracy theories. It is often emotionally driven and tailored to specific audiences. The role of social media and AI:

Open access notables Global emergence of regional heatwave hotspots outpaces climate model simulations, Kornhuber et al., Proceedings of the National Academy of Sciences: Multiple recent record-shattering weather events raise questions about the adequacy of climate models to effectively predict and prepare for unprecedented climate impacts on human life, infrastructure, and ecosystems.
