Average global temperature in November was 1.62C above preindustrial levels, bringing average for the year to 1.60C. Data for November from the EU’s Copernicus Climate Change Service (C3S) found the average global surface temperature for the month was 1.62C above the level before the mass burning of fossil fuels drove up global heating. With data for 11 months of 2024 now available, scientists said the average for the year is expected to be 1.60C, exceeding the record set in 2023 of 1.48C.

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.

Added complexity allows an economy to grow, even as resource limits are reached. But at some point, the complexity itself becomes a problem.

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.

On why collapse could be much closer than predicted: what happens when the Atlantic Ocean’s heart stops beating?

To tackle the challenges of competitiveness and well-being of future generations, Europe needs to accelerate the climate transition. This will require sizable investment, both public and private. National governments must thus embrace and the EU must facilitate investments in climate transition.

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.

Global warming has already caused the Arctic to release more climate-warming methane—but exactly how much will depend closely on the actions we take to halt climate change.

Insurance costs are rising quickly across much of the country. Hurricanes are part of the reason, but it’s the other perils common across the Midwest and Great Plains that complicate costs.

The Atlantic Meridional Overturning Circulation is the main driver of northward heat transport in the Atlantic Ocean today, setting global climate patterns. Whether global warming has affected the strength of this overturning circulation over the past century is still debated: observational studies suggest that there has been persistent weakening since the mid-twentieth century, whereas climate models systematically simulate a stable circulation. Here, using Earth system and eddy-permitting coupled ocean–sea-ice models, we show that a freshening of the subarctic Atlantic Ocean and weakening of the overturning circulation increase the temperature and salinity of the South Atlantic on a decadal timescale through the propagation of Kelvin and Rossby waves. We also show that accounting for upper-end meltwater input in historical simulations significantly improves the data–model agreement on past changes in the Atlantic Meridional Overturning Circulation, yielding a slowdown of 0.46 sverdrups per decade since 1950

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

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.

Human pressures have pushed the Earth system deep into the Anthropocene, threatening its stability, resilience and functioning. The Planetary Boundaries (PB) framework emerged against these threats, setting safe levels to the biophysical systems and processes that, with high likelihood, ensure life-supporting Holocene-like conditions. In this Review, we synthesize PB advancements, detailing its emergence and mainstreaming across scientific disciplines and society. The nine PBs capture the key functions regulating the Earth system. The safe operating space has been transgressed for six of these. PB science is essential to prevent further Earth system risks and has sparked new research on the precision of safe boundaries. Human development within planetary boundaries defines sustainable development, informing advances in social sciences. Each PB translates to a finite budget that the world must operate within, requiring strengthened global governance. The PB framework has been adopted by businesses and informed
