Many companies across the world use carbon credits as part of their climate strategies to offset emissions. A carbon credit is a certificate that represents the reduction, avoidance or removal of one ton of carbon dioxide from the atmosphere. While organizations claim these credits help them reduce their environmental impact, there is debate about whether companies that buy credits decarbonize faster. However, an in-depth study of 89 multinationals, published in Nature Communications, reveals that companies that purchase credits do not decarbonize any quicker than those that do not.

The world of cells is surprisingly noisy. Each cell carries unique genetic information, but when we try to measure cellular activity, signals can be lost or blurred, and differences between experiments can further obscure the data. These challenges have made it difficult for researchers to capture the true behavior of cells, especially when studying rare cell types or subtle changes that appear in the early stages of disease.

Last month, courts on both sides of the Atlantic delivered a clear verdict: When classifying titanium dioxide as carcinogenic, regulatory agencies had overreached.

At the end of the last ice age, billions of boulders and cobbles were left scattered over southern Scandinavia. Huge ice sheets had dragged the rocks from mountainous regions further north down to the Baltic Sea areas. When those ice sheets retreated and sea levels rose, these colossal boulders became rocky reefs, rich with marine life. These rocks formed part of a naturally resilient coast, proving a rugged structure for waves to break and reducing pressure on the seashore.

A previously unknown portrait by Pablo Picasso of one of his lovers was revealed on Thursday after being put up for sale at auction in Paris with a reserve price of eight million euros ($9.5 million).

Woods Hole Oceanographic Institution (WHOI) researchers have shown large sharks can spend hours deep in the oceans' mesopelagic zone, which lies 200 to 1,000 meters (650 to 3,300 feet) below the surface. This region is home to more biomass than any other layer of the ocean, but most of its inhabitants are too tiny to serve as meals for large predators, so why are they spending so much time there?

Wildfires, storms, and bark beetles are putting increasing pressure on Europe's forests. Beyond their ecological toll, these events also carry major economic consequences. Researchers at the Technical University of Munich (TUM) have now quantified the potential financial losses climate change could cause for European forestry. Their findings reveal significant regional differences: while Northern Europe may even benefit, Central and Southern Europe will need to adapt quickly.

This summer, the Large Hadron Collider (LHC) took a breath of fresh air. Normally filled with beams of protons, the 27-km ring was reconfigured to enable its first oxygen–oxygen and neon–neon collisions. First results from the new data, recorded over a period of six days by the ALICE, ATLAS, CMS and LHCb experiments, were presented during the Initial Stages conference held in Taipei, Taiwan, on 7–12 September.

A team of scientists at Simon Fraser University's Quantum Technology Lab and leading Canada-based quantum company Photonic Inc. have created a new type of silicon-based quantum device controlled both optically and electrically, marking the latest breakthrough in the global quantum computing race.

Increasing tree species diversity is often regarded as a way to make forests more resilient to climate change. However, a new international study led by the University of Freiburg shows that diversity can have both positive and negative effects on forests' drought resilience.

It clearly indicates that intense rainfall triggered landslides that transitioned into channelised debris flows. On 5 August 2025, a series of terrifying landslides struck Dharali in Uttarkashi, Uttarakhand, northern India. I blogged about this at the time – the Wikipedia […]

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 additional synthesis, supports a hypothesis that the net land sink is substantially weaker than commonly reported. At a global scale, our estimate of the net land carbon sink is

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 of over 60 international scientists published the latest edition of an annual report updating key metrics that are used in reports

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 absorbing and re-emitting it, they keep Earth aro

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 consumes incredible amounts of energy, and ever more of it, creating a whole new level of climate pollution that threatens to undermine those benefits. All that dizzying transformation i

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:

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. 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
