Anti-authoritarian rallies, taking place in all 50 states plus 16 countries, are expected to be biggest in US history

As climate change accelerates, its effects are being felt in every corner of the world. A comprehensive global index developed by researchers at the University of Notre Dame has assessed the climate vulnerability and adaptive readiness of nearly 200 countries, revealing stark and troubling disparities between the world’s wealthiest and most impoverished nations.

As climate and geopolitics shocks bite, countries are rebuilding food buffers. The UK clings to neoliberal ideas while households pay the price

The Global Environment Outlook, Seventh Edition: A Future We Choose, the product of 287 multi-disciplinary scientists from 82 countries, is the most comprehensive scientific assessment of the global environment ever carried out.

The latest Lancet Countdown report warns that health impacts of climate change are worsening, with millions dying needlessly each year due to fossil fuel dependence, growing greenhouse gas emissions, and failure to adequately adapt. As some countries and companies rollback on climate commitments, local and grassroots leadership is building momentum for a healthier future.​ The report represents the work of 128 experts from 71 institutions, monitoring progress across 57 indicators – from heat-related deaths to bank lending to fossil fuels – providing the most comprehensive assessment yet of the links between climate change and health.

Unless global heating is reduced to 1.2C ‘as fast as possible’, warm water coral reefs will not remain ‘at any meaningful scale’, a report by 160 scientists from 23 countries warns

Report cites scale of killings and aid blockages, and calls on member countries to punish those responsible

How does one talk about climate change when armed conflicts are spiralling out of control?

Almost 100 countries reject draft treaty as ‘unambitious’ and ‘inadequate’

When people reflect on how their actions shape the future, they are more likely to support solutions to present-day issues like poverty and inequality.

Eat-Lancet report recommended shift to more plant-based, climate-friendly diet but was extensively attacked online [...] The report recommended that if global red meat eating was cut by 50%, the “planetary health diet” would provide nutritious food to all while tackling the harms caused by animal agriculture, which accounts for over 14% of all greenhouse gas emissions worldwide. It suggested individuals – particularly in wealthy countries – should increase their consumption of nuts, pulses and other plant-based foods while cutting meat and sugar from their diets.

Countries must move rapidly to slash CO2 emissions from homes, offices, shops and other buildings—a sector that accounts for a third of global greenhouse gas pollution, the United Nations said Monday. Carbon dioxide emissions from the building sector rose around 5% in the last decade when they should have fallen 28%, according to a new report by the United Nations Environment Program (UNEP).

Developing countries urge biggest polluters to act as Trump’s return to the White House heightens geopolitical turmoil

The multibillion-dollar chemicals company 3M told customers its firefighting foams were harmless and biodegradable when it knew they contained toxic substances so persistent they are now known as “forever chemicals” and banned in many countries including the UK, newly uncovered documents show.

UN Secretary-General António Guterres called for making 2025 “a new beginning” in his message for the New Year, issued on Monday.

People around the world suffered an average of 41 extra days of dangerous heat this year because of human-caused climate change. The figure comes from analysis done by researchers at World Weather Attribution and Climate Central. In 2024 climate records were shattered as heat across the globe made it likely to be the hottest year ever measured, with few countries spared fatal weather events.

Some narratives in international development hold that ending poverty and achieving good lives for all will require every country to reach the levels of GDP per capita that currently characterise high-income countries. However, this would require increasing total global output and resource use several times over, dramatically exacerbating ecological breakdown. Furthermore, universal convergence along these lines is unlikely within the imperialist structure of the existing world economy. Here we demonstrate that this dilemma can be resolved with a different approach, rooted in recent needs-based analyses of poverty and development. Strategies for development should not pursue capitalist growth and increased aggregate production as such, but should rather increase the specific forms of production that are necessary to improve capabilities and meet human needs at a high standard, while ensuring universal access to key goods and services through public provisioning and decommodification. At the same time, in high

The big question: Would climate engineering like sending reflective particles into the stratosphere or brightening clouds help reduce the national security risks of climate change or make them worse?

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