Global warming could reach 7ºC, study shows

O study (🇬🇧) was prepared under the guidance of American climatologist James Hansen – who was the first scientist to say, in 1988, that the global warming was already underway. The research carried out by him and 14 co-authors is in the preprint, awaiting review by other scientists for definitive publication.

The main discovery is related to an indicator called climate sensitivity in balance (ECS) on the planet. This is an estimate of how much the temperature on Earth would increase if the concentration of carbon dioxide (CO2) in the atmosphere doubled.

In short, the team of scientists suggests that the planet's climate sensitivity is greater than previously imagined — which, given the current concentration of greenhouse gases in the atmosphere, produces a scenario of more heating and less time than expected.

'Green tariffs': what are they and why are they important?

The European Union (EU) has become the first major economy to legislate a 'green tariff' on imports, to be levied on goods produced with high carbon dioxide (CO2) emissions. The Carbon Border Adjustment Mechanism (CBAM) means that countries that fail to green their industries will soon face a new threat: an effective carbon tax that will penalize those hoping to profit from high-carbon activities. The system will initially be applied to iron and steel, cement, fertilizers, aluminum, electricity, hydrogen and some chemical products. But do you know what this 'green tariff' means? How can it force corporations to adapt to a more sustainable production process?
