The situation is worse than previously thought In February 2025, three scientific papers were published showing that the climate situation is much worse than the scientific community thought, much less what is thought by the people to whom President Luiz Inácio Lula da Silva (known simply as “Lula”) really listens – his Minister of Mines and Energy and the President of the government oil company (Petrobras). The first paper, published in the journal Environment: Science and Policy for Sustainable Development on February 3, is led by the renowned climate scientist James Hansen. It shows that the effect of aerosols and other forms of atmospheric pollution have masked the real power of greenhouse gases already present in the atmosphere, and that the rate of warming in the coming years would be much greater than previously thought. This means that the climate is rapidly advancing towards a point of no return, where global warming would escape the possibility of human control. Hansen, who is famous for being the NASA scientist who challenged the climate denialism of then-US President George W. Bush, made a statement to the press at the time of the release of the current paper that the goal of keeping the global average temperature below 2°C (3.6°F) above the pre-industrial average is “dead.” If true, it is very serious, since even the current limit in the Paris agreement of 1.5°C (2.7°F) implies a substantial risk of warming escaping from control (see here and here), as well as of the Amazon…This article was originally published on Mongabay
