Open access notables The first emergence of unprecedented global water scarcity in the Anthropocene, Ravinandrasana & Franzke, Nature Communications Access to water is crucial for all aspects of life. Anthropogenic global warming is projected to disrupt the hydrological cycle, leading to water scarcity. However, the timing and hotspot regions of unprecedented water scarcity are unknown. Here, we estimate the Time of First Emergence (ToFE) of drought-driven water scarcity events, referred to ...| Skeptical Science
This is a re-post from The Climate Brink by Kevin Trenberth A new analysis issued by the National Academies of Science, Engineering, and Medicine (NASEM) found that the evidence linking rising greenhouse gas emissions to negative human health outcomes is “beyond scientific dispute.” Climate change is real and it has already resulted in major damage. The main cause is increasing atmospheric greenhouse gases of carbon dioxide, methane and nitrous oxide, all from human activities. Because...| Skeptical Science
Skeptical Science is partnering with Gigafact to produce fact briefs — bite-sized fact checks of trending claims. You can submit claims you think need checking via the tipline. Are humans responsible for climate change? Our rapid burning of fossil fuels has caused a buildup of heat-trapping carbon dioxide gas in our atmosphere. Until we started burning fossil fuels, the CO2 moving between the Earth’s atmosphere, oceans and land remained relatively steady for thousands of years. Fossil fu...| Skeptical Science
This is a re-post from The Climate Brink I have a new guest essay in the New York Times with David Keith that builds off my earlier Climate Brink post The Geoengineering Question. Below I’ve included some more detailed thoughts that couldn’t make it into the published piece given the word limit constraints. We are already geoengineering the planet today, but badly. Humans are cooling the climate today by emitting 75 million metric tons of sulfur dioxide into the lower atmosphere, almo...| Skeptical Science

This is a re-post from The Climate Brink by Andrew Dessler Let’s run a thought experiment. Imagine that you’re the Secretary of Energy. But you’re not just any public servant. You're a former fossil fuel executive, and you’re cartoonishly, mustache-twirlingly evil. Your singular goal is to keep America hooked on fossil fuels — a dirty, expensive product that enriches you personally — by slowing as much as possible the deployment of clean, cheap renewable energy that benefits ev...| Skeptical Science
Open access notables Changes Observed in Cloud-Top Heights by MISR From 2002 to 2021, Davies & Moroney, Journal of Geophysical Research: Atmospheres We analyzed cloud heights measured by the Multiangle Imaging SpectroRadiometer on the Terra satellite from 1 April 2002–31 March 2021. Throughout these 19 years, the equatorial crossing time of Terra's orbit varied by less than 1 min from its mean value. This variation created a homogeneous time series of deseasonalized and deregionalized he...| Skeptical Science
This is a re-post from And Then There's Physics It seems that the US Department of Energy has now disbanded the Climate Working Group that drafted the report that I discussed in this post. However, about a week ago, Steven Koonin – one of the authors of the report – had an article in the Wall Street Journal titled At Long Last, Clarity on Climate. Clarity is a bit of a stretch. Personally, I think it more muddied the waters, than brought clarity. A general point that I didn’t reall...| Skeptical Science

Has the IPCC overestimated climate change impacts? The Intergovernmental Panel on Climate Change compiles the consensus of thousands of models, and many independent lines of research suggest its estimates were more conservative than what was subsequently observed. For example, sea-level rise predictions in earlier I...| Skeptical Science

Open access notables The weak land carbon sink hypothesis, Randerson et al., Science Advances Over the past three decades, assessments of the contemporary global carbon budget consistently report a strong net land carbon sink. Here, we review evidence supporting this paradigm and quantify the differences in global and Northern Hemisphere estimates of the net land sink derived from atmospheric inversion and satellite-derived vegetation biomass time series. Our analysis, combined with addition...| Skeptical Science
This is a re-post from Yale Climate Connections he amount of heat trapped by climate-warming pollution in our atmosphere is continuing to increase, the planet’s sea levels are rising at an accelerating rate, and the Paris agreement’s ambitious 1.5°C target is on the verge of being breached, according to a recent report by the world’s top climate scientists. “The news is grim,” said study co-author Zeke Hausfather, a former Yale Climate Connections contributor, on Bluesky. A team...| Skeptical Science
This is a re-post from Yale Climate Connections by Daisy Simmons Is AI saving the world or breaking it? As the era-defining technology leapfrogs from what-if to what-next, it can be hard for us humans to know what to make of it all. You might be hopeful and excited, or existentially concerned, or both. AI can track Antarctic icebergs 10,000 times faster than humans and optimize renewable energy grids in real time – capabilities that could help us fight climate change. But it also consume...| Skeptical Science

Has the greenhouse effect been falsified? The greenhouse effect is basic physics that has been known for nearly 200 years. Without it, the Earth would not be warm enough for life. Greenhouse gases like carbon dioxide act like an insulating blanket. By preventing some outgoing heat from escaping the atmosphere by abs...| Skeptical Science
