Among the many things global warming will be melting this century—sea ice, land glaciers and tourist businesses in seaside towns across the world—is permafrost. Lying underneath 15% of the northern hemisphere, permafrost consists of accumulating dead biomass that remains frozen, never having had a chance to release all its carbon.

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.

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 sudden collapse of carbon sinks was not factored into climate models – and could rapidly accelerate global heating

In 2023, the CO2 growth rate was 3.37 ± 0.11 ppm at Mauna Loa, 86% above the previous year, and hitting a record high since observations began in 1958[1], while global fossil fuel CO2 emissions only increased by 0.6 ± 0.5%[2,3]....

Offsetting allows corporations to increase emissions, while getting credit for pseudo-reductions elsewhere

A carbon bomb is any fossil fuel extraction project that will generate more than one gigatonne of carbon dioxide (1GtCO2) over its remaining life.

Carbon Brief provides an updated analysis of when the world will likely exceed the Paris 1.5C limit

Historical responsibility for climate change is radically shifted when colonial rule is taken into account, Carbon Brief analysis reveals.

Natural ecosystems store large amounts of carbon globally, as organisms absorb carbon from the atmosphere to build large, long-lasting, or slow-decaying structures such as tree bark or root systems. An ecosystem’s carbon sequestration potential is tightly linked to its biological diversity. Yet when considering future projections, many carbon sequestration models fail to account for the role biodiversity plays in carbon storage. Here, we assess the consequences of plant biodiversity loss for carbon storage under multiple climate and land-use change scenarios. We link a macroecological model projecting changes in vascular plant richness under different scenarios with empirical data on relationships between biodiversity and biomass. We find that biodiversity declines from climate and land use change could lead to a global loss of between 7.44-103.14 PgC (global sustainability scenario) and 10.87-145.95 PgC (fossil-fueled development scenario). This indicates a self-reinforcing feedback loop, where higher levels

China’s CO2 emissions fell by 3% in March 2024, ending a 14-month surge that began when the economy reopened after the nation’s “zero-Covid”

Over the past year, there has been a vigorous debate among scientists – and more broadly – about whether global warming is “accelerating”.

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

Global investment in the clean energy transition grew by 17% in 2023, showing resilience despite geopolitical tensions, high interest rates, and inflation. But was it enough to keep the world on track to hit net zero by 2050? To answer this question, we compare 2023 clean energy investment by sector with what’s annually needed to reach net zero by 2050, in partnership with the National Public Utilities Council.

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.

The auto industry is making too many cars powered by fossil fuels.

EUCityCalc has officially launched its free, open source online platform that allows local councils and other stakeholders to visualise and simulate low-carbon scenarios for their towns and cities, as well as to assess the trade-offs related to available choices.

The European Commission has received an open letter signed by 110 academics, businesses, civil society organisations and research institutions urging the EU to separate emissions reductions, land-based sequestration and permanent carbon removals in the EU’s post-2030 climate framework. This separation should be at the heart of both the setting and the implementation of the 2040 target and associated plans.

At a time when we need to shift our collective climate action up a gear, the influence of the fossil fuels lobby is succeeding in slowing down ambition both at COP27 and in the EU.

To truly evaluate your impact on the environment, you have to go way beyond recycle bins and energy bills...
