Hastened reviews of compounds as industry ramps up could increase pollution from likely toxic chemicals. The Environmental Protection Agency is quietly fast tracking approval of new PFAS “forever chemicals” for use by the semiconductor industry at the same time the agency is publicly touting increased scrutiny of new PFAS and other chemicals.

We are used to thinking about natural disasters as events confined in time and space: the direct impact in a certain location of an earthquake happens over minutes, a hurricane over hours. While they might be confined in geography, longitudinal studies can help us understand the full range of effects and what extra efforts might be needed to rebuild.

The new study, led by researchers at the Global Systems Institute, University of Exeter, associated with the Earth Commission, and Nanjing University, assessed what this would mean for the number of people living outside the “climate niche” in which our species has thrived. It says about 60 million people are already exposed to dangerous heat (average temperature of 29°C or higher). And two billion – 22% of the projected end-of-century population – would be exposed to this at 2.7°C of global warming.

An MIT Energy Initiative study finds many climate-stabilization plans are based on questionable assumptions about the future cost and deployment of “direct air capture” and therefore may not bring about promised reductions.

Trump could reverse the nation’s progress on climate change, but rolling back the Biden administration’s significant climate successes could be a low, slow and difficult process...

Top officials in Baku for COP29 say the spread of false climate narratives undercuts the annual climate talks.

This research reinforces the scientific consensus that the only viable strategy to limit catastrophic climate change requires drastic and immediate emissions cuts. An important study was published last month in the journal Nature, titled “Overconfidence in climate overshoot.” While increasingly dire warnings of the catastrophic impacts of global climate change continue to be published by scientists, the findings of this new paper provide another stark reminder of the urgent necessity to limit global warming by immediately reducing greenhouse gas (GHG) emissions.

A 1972 MIT study predicted that rapid economic growth would lead to societal collapse in the mid 21st century. A new paper shows we’re unfortunately right on schedule.

Disruption of the Atlantic Meridional Overturning Current could freeze Europe, scorch the tropics and increase sea level rise in the North Atlantic. The tipping point may be closer than predicted in the IPCC’s latest assessment.

Scientists may have to rethink the relationship between the ocean’s circulation and its long-term capacity to store carbon, new research from MIT suggests. As the ocean gets weaker, it could release more carbon from the deep ocean into the atmosphere — rather than less, as some have predicted.

The results of one election can’t stop the momentum of the energy transition. But they can do a lot of damage.

A Trump presidency can delay, but not stop, the global transition to renewable energy, but it may more effectively stymie progress than during his first term.

A new declaration aims to make the southernmost continent an autonomous legal entity, akin to a nation-state, with inherent rights to participate in decision making that affects it.

The election of Donald Trump as president for a second time and the Republican takeback of the U.S. Senate could undo many of the national climate policies that are most reducing planet-warming greenhouse gas emissions, according to climate solutions experts.When they list measures that are making the most difference, it lines up with policies Trump has said he’ll target. These rollbacks will come as more lives are being lost in heat waves, record amounts of climate pollution are accumulating in the atmosphere, the United States has been hit with what may be two of its most expensive hurricanes, and nations, which will meet in Baku, Azerbaijan next week for climate negotiations, have failed to take strong action to change these realities.

AMOC collapse would bring severe global climate repercussions, with Europe bearing the brunt of the consequences.

We are on the brink of an irreversible climate disaster. This is a global emergency beyond any doubt. Much of the very fabric of life on Earth is imperiled. We are stepping into a critical and unpredictable new phase of the climate crisis. For many years, scientists, including a group of more than 15,000, have sounded the alarm about the impending dangers of climate change driven by increasing greenhouse gas emissions and ecosystem change (Ripple et al. 2020).

As a six-year investigation into the Thwaites glacier in Antarctica wraps up, the scientists involved are pessimistic for the future of this glacier and the consequences for sea level rise

High-level policy discussions have built momentum for “food system transformation” that would help farmers address the climate crisis.

A case in point: When Ecuador placed a windfall tax on foreign oil operations, French and U.S. companies filed claims—and were awarded more than $800 million.

New studies suggest global warming boosts natural methane releases, which could undermine efforts to cut emissions of the greenhouse gas from fossil fuels and agriculture.
