The 30th Conference of the Parties (COP30) to the United Nations Framework Convention on Climate Change officially kicked off in the city of Belém (Brazil), marking the first time the global climate summit has been held in the heart of the Amazon rainforest.

Researchers from France and Brazil are meeting this week in Belém, in the State of Pará, to launch a new season of the Amazon Connections Seminar addressing the planet’s future from scientific, cultural, and political perspectives. The gathering will span until Aug. 29 at the Emílio Goeldi Museum in Belém, the host city of COP30, as part of the bilateral agenda held each year in two seasons—one in each country.

During his recent trip to Brazil, former US Vice President Al Gore said that his country's stance on the climate crisis was schizophrenic, changing from one view to another, depending on who ruled. In his first term in office, between 2017 and 2021, Donald Trump withdrew the US from the Paris Agreement, whose main objective is to limit global warming to 1.5°C. But then came Joseph Biden, and the country returned to the agreement, only to pull out yet again with Trump's second term.

By Gwynne Dyer - Some big changes arrive with a bang, but usually they sort of sneak in and you barely notice them at first. Last week’s big change saw the creation of the world’s first climate-change visas. It’s a way of giving potential climate refugees some hope and some dignity, and it would certainly be an improvement on the current migration mess.

A forum of Academies of Science of the BRICS bloc in Rio de Janeiro issued a declaration this week proposing the creation of a network of member countries to implement climate solutions, focusing on energy transition technologies and the development of joint artificial intelligence programs.

Greenland experienced a melting rate 17 times faster than average last month due to record-high temperatures, while Iceland saw temperatures exceed 26°C, the European Copernicus Observatory reported this week.

Brazil topped the world last year in forest fires, accounting for 42% of the global loss of primary tropical forests. The extreme heat of the year, exacerbated by climate change and El Niño, intensified fires, which destroyed more forest than agribusiness activities for the first time. The worst drought ever recorded contributed to a sixfold increase in fire-related deforestation compared to 2023.
