Open access notables Wild, scenic, and toxic: Recent degradation of an iconic Arctic watershed with permafrost thaw, Sullivan et al., Proceedings of the National Academy of Science The streams of Alaska’s Brooks Range lie within a vast (~14M ha) tract of protected wilderness and have long supported both resident and anadromous fish. However, dozens of historically clear streams have recently turned orange and turbid. Thawing permafrost is thought to have exposed sulfide minerals to weathering, delivering iron and other potentially toxic metals to aquatic ecosystems. Here, we report stream water metal concentrations throughout the federal

This is a re-post from The Climate Brink by Andrew Dessler My last post described our 450-page response to the DOE Climate Working Group report. This DOE report seems designed to muddy the waters about climate science — it’s a new iteration of the Merchants of Doubt. We found the report used selective misquoting of the scientific literature (cherry picking), omission of contrary results from the scientific literature, and simple errors due to a lack of understanding of the science to reach its conclusions. Further commentary of the process is in this post. A reporter asked me for a comment on a post on Dr. Judy Curry’s blog about our review of the DOE Climate Working Group report. In her post, she said:

Has Arctic sea ice recovered? Arctic sea ice, in both extent and volume, continues to decline. The only fair comparison for Arctic sea ice is to a full 12 months prior, as ice accumulates each winter and melts each summer. By that metric, Arctic sea ice extent set a record low maximum in March 2025, the month when ice is at its highest. Arctic sea ice vo

This is a re-post from The Climate Brink by Andrew Dessler If you don’t follow climate policy closely, you may not know that the Trump administration is launching an effort to overturn one of the most fundamental pillars of American climate policy: the scientific finding that carbon dioxide endangers human health and welfare (the so-called “Endangerment Finding”). If successful, this move could unravel virtually every U.S. climate regulation on the books, from car emissions standards to power plant rules. To support this effort, the Department of Energy

This video includes personal musings and conclusions of the creator climate scientist Dr. Adam Levy. It is presented to our readers as an informed perspective. Please see video description for references (if any). As the northern hemisphere experiences summer, we have also been experiencing the disastrous impacts of climate change - extreme weather like heatwaves droughts; records being smashed time and time again; and wildfires raging through our cities and our forests. But despite the fact that we're seeing unprecedented conditions, some are still claiming that all this can be explained by simply saying "It's Called Summer". But this form of climate denial - that today's conditions are normal summer, rather than a symptom of a changed climate - is surprisingly widespread... despite also being nonsensical. In this video, I get into why this kind of argument holds back climate action. Su

Is global warming actually happening? Multiple indicators show Earth is warming rapidly. Global surface temperatures are now about 1.47°C (2.65°F) above the 19th century average, with the past ten years the warmest on record. Surface temperatures are measured by thousands of land weather stations and weather balloons, along with ships, ocean buoys, an
