Climate activists opposed to the Mountain Valley pipeline were accused of breaking West Virginia’s new critical infrastructure law

Global average surface temperatures shattered all-time records in 2023 at 1.45 ± 0.12 ◦C above pre- industrial levels (WMO 2024). Worsened by climate change-induced drought, Canadian wildfires burned 18.5 million hectares, nearly three-times more land area than in any previous year on record (NRC 2023).

The EU is being sued for failing to set ambitious climate targets in sectors that contribute more than half of the bloc’s total greenhouse gas emissions.

A short glossary of the changes we’ve made to the Guardian’s style guide, for use by our journalists and editors when writing about the environment

Blackened trees, dead animals and scorched earth – early wildfires have already devastated Brazil’s Pantanal and local people worry they may lose the battle to save them

Since the Paris Agreement in 2016, the world’s 60 largest private banks financed fossil fuels with USD $6.9 trillion. Nearly half – $3.3 trillion – went towards fossil fuel expansion. In 2023, banks financed $705 billion in fossil fuel financing with $347 billion going to fossil fuel expansion alone.

Cultured meat is an emerging biotechnology that aims to produce meat from animal cell culture, rather than from the raising and slaughtering of livestock, on environmental and animal welfare grounds. The detailed understanding and accurate manipulation of cell biology are critical to the design of cultured meat bioprocesses. Recent years have seen significant interest in this field, with numerous scientific and commercial breakthroughs. Nevertheless, these technologies remain at a nascent stage, and myriad challenges remain, spanning the entire bioprocess. From a cell biological perspective, these include the identification of suitable starting cell types, tuning of proliferation and differentiation conditions, and optimization of cell–biomaterial interactions to create nutritious, enticing foods. Here, we discuss the key advances and outstanding challenges in cultured meat, with a particular focus on cell biology, and argue that solving the remaining bottlenecks in a cost-effective, scalable fashion will req

Global projections of macroeconomic climate-change damages typically consider impacts from average annual and national temperatures over long time horizons1–6. Here we use recent empirical findings from more than 1,600 regions worldwide over the past 40 years to project sub-national damages from temperature and precipitation, including daily variability and extremes7,8. Using an empirical approach that provides a robust lower bound on the persistence of impacts on economic growth, we find that the world economy is committed to an income reduction of 19% within the next 26 years independent of future emission choices (relative to a baseline without climate impacts, likely range of 11–29% accounting for physical climate and empirical uncertainty). These damages already outweigh the mitigation costs required to limit global warming to 2 °C by sixfold over this near-term time frame and thereafter diverge strongly dependent on emission choices. Committed damages arise predominantly through changes in average tempe

Carbon Brief explores which countries are or have targets to be net-negative, and the moral and scientific arguments for such a milestone.

A recent paper suggested damaging climate tipping points could be closer than first thought.

Current methods to calculate the so-called social cost of carbon largely leave out how many future people our emissions will kill. This study tries to correct that.

RealClimate: A new paper was published in Science Advances today. Its title says what it is about: "Physics-based early warning signal shows that AMOC is on tipping course." The study follows one by Danish colleagues which made headlines last July, likewise looking for early warning signals for approaching an AMOC tipping point (we discussed it here),

Alberta owns a new record. The province is home to an abandoned and unplugged gas well that leaks methane, an explosive greenhouse gas, into the atmosphere at the highest rate ever recorded in North America.

World Meteorological Organization says 2023 will be hottest year on record, leaving ‘trail of devastation and despair’

Global fall averaged 4.2% between 2010 and 2022 but would have been far more if vehicle sizes stayed same

By putting in place climate change adaptation measures, NATO has an opportunity to both strengthen operational resilience and adapt to the impacts of climate change.

Study highlights conflict between Washington’s claims of climate leadership and its fossil fuel growth plans

More than a century of research shows that burning fossil fuels warms the climate – that’s exactly why granting new North Sea oil and gas licenses is a bad idea.

A collapse would bring catastrophic climate impacts but scientists disagree over the new analysis

Energy firms have made record profits by increasing production of oil and gas, far from their promises of rolling back emissions
