Marina Silva says contentious plan would be ‘ethical answer’ to climate crisis but does not commit Brazil to it

Brazil’s environment minister, Marina Silva, has urged all countries to have the courage to address the need for a fossil fuel phaseout, calling the drawing up of a roadmap for it an “ethical” response to the climate crisis.

She emphasised, however, that the process would be voluntary for those governments that wished to participate, and “self-determined”.

With temperatures breaching the Paris limit, experts say tackling the powerful gas could buy crucial time as the clean-energy shift stalls

For two years, global temperatures have exceeded the 1.5C heating limit laid out in the Paris climate agreement. This overshooting will have “devastating consequences”, the UN secretary general, António Guterres, has warned.

The biggest worry for scientists is that further heating could trigger irreversible tipping points, such as the widespread drying out and dying off of the Amazon, or the melting of the Greenland ice sheet, beyond which climate breakdown could spiral out of control.

Brazil’s president welcomes world leaders while navigating divided government, promising action on deforestation and emissions

• How could the Tropical Forest Forever Facility tackle deforestation?

Brazil’s president, Luiz Inácio Lula da Silva, has welcomed world leaders to Belém for the first climate summit in the Amazon, where conservationists hope he can be a champion for the rainforest and its people.

But with a divided administration, a hostile Congress and 20th-century developmentalist instincts, this global figurehead of the centre left has a balancing act to perform in advocating protection of nature and a reduction of emissions.

Money talks – and his essay denouncing ‘near-term emissions goals’ at Cop30 mostly argues the case for letting the ultra-rich off the hook

Let’s begin with the fundamental problem: Bill Gates is a politics denier. Though he came to it late, he now accepts the realities of climate science. But he lives in flat, embarrassing denial about political realities. His latest essay on climate, published last week, treats the issue as if it existed in a political vacuum. He writes as if there were no such thing as political power, and no such thing as billionaires.

His main contention is that funds are very limited, so the delegates at this month’s climate summit in Brazil should direct money away from “near-term emissions goals” towards climate “adaptation” and spending on poverty and disease.

Host uses Indigenous concepts and changes agenda to help delegates agree on ways to meet existing climate goals

Shipping containers, cruise ships, river boats, schools and even army barracks have been pressed into service as accommodation for the 50,000 plus people descending on the Amazon: this year’s Cop30 climate summit is going to be, in many ways, an unconventional one.

Located in Belém, a small city at the mouth of the Amazon river, the Brazilian hosts have been criticised for the exorbitant cost of scarce hotel rooms and hastily vacated apartments. Many delegations have slimmed down their presence, while business leaders have decamped to hold their own events in São Paulo and Rio de Janeiro.

The increasing ferocity and frequency of tropical storms imposes an unbearable burden on countries including Jamaica

The geographically uneven risks from increasingly extreme and dangerous weather grow ever starker. As Jamaica and other Caribbean countries clear up after Hurricane Melissa, and Typhoon Kalmaegi heads west after killing nearly 200 people in the Philippines and Vietnam, the case for more international support to countries facing the most destructive impacts from global heating has never been stronger.

Last week’s five-day rainfall in Jamaica was made twice as likely by higher temperatures, according to initial findings from climate attribution studies. The current death toll across the Caribbean is at least 75. The economic and social costs are hard to quantify in a region that is still recovering from 2024’s Hurricane Beryl. Crucial infrastructure has been destroyed before the loans used to build it have even been paid off. Andrew Holness, Jamaica’s prime minister, estimates that the damage there is roughly equivalent to one-third of the country’s gross domestic product.

James Marape skipped the meeting last year in protest but will attend Cop30 due to ‘encouraging signs’ on climate finance

Papua New Guinea’s prime minister, James Marape, has criticised Cop climate summits as “long on talk and short on action” but will attend the upcoming meeting of world leaders in Brazil, after pulling out last year in frustration with big emitters.

The leader of the Pacific nation of about 10 million people skipped the meeting in 2024 in “protest at the big nations” for failing to support to the victims of climate change. Marape will take part in the annual UN climate summit, which officially beings in Belém, Brazil on 10 November, due to “encouraging signs” emerging from developed nations on climate finance.

UK expected to reduce contribution to Global Fund to Fight Aids, Tuberculosis and Malaria by 20%

A group of seven Labour MPs who served as ministers under Keir Starmer have written to the prime minister warning that an expected cut to UK funding for aid to combat preventable diseases would be both a “moral failure” and a strategic disaster.

With ministers and officials expected to decide the UK’s contribution to the Global Fund to Fight Aids, Tuberculosis and Malaria within days, the letter renews pressure on Starmer to pull back from an expected 20% cut.
