Adaptation planning should include the impacts that can be avoided by high mitigation ambition – including which impacts are reversible from overshooting the 1.5°C limit and which are irreversible. This includes mitigation actions themselves, such as carbon dioxide removal, to avoid land use challenges.

Methane is a highly potent but short-lived greenhouse gas, and its emissions are rising globally and across all sectors. Taking strong action this decade, especially in the energy sector, is necessary to deliver rapid climate benefits and keep the 1.5°C Paris Agreement goal within reach.

Countries need coherent systems to manage the growing complexity of climate finance. CFUs offer a promising solution.

The role of the Intergovernmental Panel on Climate Change in providing science input into the Paris Agreement and its critical five yearly Global Stocktake is under challenge.

COP29 concluded with more than a few agenda items left unresolved. One was the 'just transition work programme'. What happened during these negotiations? And how can we ensure a better outcome at COP30?

Two new papers published in Nature Climate Change today ask whether the recent global temperatures at or exceeding 1.5° warming above preindustrial mean the Paris Agreement’s 1.5°C limit has been reached or will soon be?

The Global Carbon Budget's first estimate for 2024's CO2 emissions suggests emissions rose by 0.8% this year. We delve into why we haven't peaked emissions yet.

We break down the transformational changes needed in the power, buildings, transport and agriculture sectors to slash greenhouse gas emissions over the next decade.
