The South American hydropower facility set records for energy generation

On average, Itaipu generates around 90 terawatt-hours of electricity annually. It set a record by generating 103.1 TWh in 2016 (surpassed in 2020 by Three Gorges’ 111.8-TWh output). To put 100 TWh into perspective, a power plant would need to burn approximately 50 million tonnes of coal to produce the same amount of energy, according to the U.S. Energy Information Administration.

One of the most important documentary films about fascism by Soviet director Mikhail Romm. Based entirely on newsreel shooting by cinematographers and photographers from Germany, the Soviet Union, the United States, Italy, Britain, and other countries, the film is based on authentic documents from numerous historical archives. The entire film is accompanied by the voiceover of film director Mikhail Romm. With anger and pain, with deep sadness, and at times with a murderous irony, he comments on events, reflects on dictatorships and dictators, on the crowd that submits to them and deifies them, speaking confidentially to the viewer. With his outstanding film, Mikhail Romm truly revolutionized documentary filmmaking.

Experts say proposed deal with U.S. makes no sense

“If you want critical minerals, Ukraine ain’t the place to look for them,” declares Jack Lifton, executive chairman of the Critical Minerals Institute. “It’s a fantasy. There’s no point to any of this. There’s some other agenda going on here. I can’t believe that anybody in Washington actually believes that it makes sense to get rare earths in Ukraine.”

Wildlife charity backs policy of exploitation of small number of some endangered species for economic purposes – such as trophy hunting.

The wildlife charity WWF has been working to support the trade in polar bear fur at the same time as using images of the bears to raise money, it can be revealed.

Polar bears are severely affected by the loss of Arctic sea ice, which makes seeking prey harder and forces the bears to use more energy. In some regions, polar bears are showing signs of declining physical condition, having fewer cubs, and dying younger.

Despite their endangered status, polar bears are hunted commercially in Canada, the only country that still allows the practice after it was banned by Russia, Greenland, the US and Norway. An annual average of 300–400 skins are exported, primarily to China, where a full pelt sells for an average of $60,000 (£48,000) and is often used for luxury clothing or as a rug.

Além de mandar a carta para a ONU, o governo americano ainda afirmou que não enviará seu secretário de Estado, Marco Rubio, para a reunião do G20 na África do Sul. Oficialmente, o chefe da diplomacia americana alegou que não iria por conta de uma insatisfação do governo Trump com a política de distribuição de terras do governo local.

"A África do Sul está fazendo coisas muito ruins. Expropriando a propriedade privada. Usando o G20 para promover 'solidariedade, igualdade e sustentabilidade'. Em outras palavras: DEI [diversidade, equidade e inclusão] e mudança climática", disse Rubio em uma postagem no X. "Meu trabalho é promover os interesses nacionais dos Estados Unidos, não desperdiçar o dinheiro do contribuinte ou mimar o antiamericanismo", completou.

Ao tomar posse, Trump chamou o acordo de "um roubo". "Não vamos sabotar nossa indústria, enquanto a China polui", disse.

Durante seu discurso, ele ainda debochou da produção de energia eólica. "Não vamos fazer nada com essa coisa de vento", disse. "Vamos economizar US$ 1 trilhão ao sair do acordo", insistiu. Enquanto assinava uma carta para a ONU informando da saída dos EUA, o público xingava a entidade.

EU monitor says global temperatures were 1.75C above preindustrial levels, extending run of unprecedented highs

Climate scientists had expected this exceptional spell to subside after a warming El Niño event peaked in January 2024 and conditions shifted to an opposing, cooling La Niña phase. But the heat has lingered at record or near-record levels, prompting debate about what other factors could be driving it to the top end of expectations.
