New research published Monday concludes that deforestation in the Amazon has a more drastic and long-reaching warming effect on non-local land surfaces than previously known, suggesting an even greater importance for forestry projects located in the world's largest rainforest.

The EU should set binding soil health targets for member states, provide tailored government support for farmers, and do more to involve the private sector to ensure soil contributes to the growth of the bloc's carbon sink by the end of the decade, according to an NGO report compiling stakeholder views published on Tuesday.

The troubled Kariba REDD project suffered another blow to its reputation on Tuesday after a rating agency downgraded its carbon credits to the lowest possible score, but also took the unusual step of delisting the project from further assessment in the future.

Researchers find the plants don’t use conventional processes to follow the sun across the sky

With their bright yellow manes and sturdy stems, sunflowers might seem like a simple summer delight. But researchers say the plants are surprisingly enigmatic after discovering they don’t use conventional processes to track the sun across the sky.

Over the course of a day, sunflowers follow the path of the sun overhead – a process known as heliotropism – with their heads tilting progressively westwards as a result of cells elongating on the east side of the stem.

‘Nothing’s changed’ stance by Murray Auchincloss needs time despite sceptism of investors

• BP plays down takeover speculation after lower than expected profits

“We remain committed to executing our strategy,” said Murray Auchincloss, BP’s stand-in chief executive, for the umpteenth time since Bernard Looney was defenestrated as permanent boss seven weeks ago. Auchincloss’s problem is that repetition doesn’t make it more convincing in the eyes of a sceptical market. Investors were already wondering if Looney would bow to pressure to water down his green transition plans further. Now it’s open season for speculation about BP’s future. Takeover target? Breakup candidate? There is an air of instability.

That is partly because the two biggest US oil majors are seemingly more confident than ever in their hydrocarbons-for-longer strategies. ExxonMobil is buying the US shale group Pioneer for $60bn (£49bn) and Chevron is making a record purchase by paying $53bn for Hess, complete with access to Guyana’s offshore oil reserves. Both deals are a case of doubling down on fossil fuels, which naturally provokes a fresh round of muttering among a few BP investors about whether renewables will ever earn the same returns on capital as oil and gas. BP’s shares are persistently priced at a valuation discount to those of the US majors.

The growing inclination for farmers to generate and sell carbon credits, rather than help their food and agricultural clients achieve their insetting objectives, could hinder supplier relationships in the agricultural sector, a global business association representative told a conference this week. 

When Rishi Sunak granted 27 new North Sea licences this week, he wasn’t thinking about the survival of the living world

Can you see it yet? The Earth systems horizon – the point at which our planetary systems tip into a new equilibrium, hostile to most lifeforms? I think we can. The sudden acceleration of environmental crises we have seen this year, coupled with the strategic uselessness of powerful governments, rushes us towards the point of no return.

We’re told we are living through the sixth mass extinction. But even this is a euphemism. We call such events mass extinctions because the most visible sign of the five previous catastrophes of the Phanerozoic era (since animals with hard body parts evolved) is the disappearance of fossils from the rocks. But their vanishing was a result of something even bigger. Mass extinction is a symptom of Earth systems collapse.

French banks have financed $154bn to firms running biggest fossil fuel projects since 2015 climate pact

France is Europe’s biggest supporter of “carbon bomb” extraction projects that hold enough fossil fuels to pump out more than a gigaton of CO2 each, the Guardian can reveal.

Since world leaders gathered in the French capital to sign the Paris agreement in 2015 – where they promised to try to stop the planet heating by 1.5C above pre-industrial levels – French banks have financed companies planning or operating carbon bombs amounting to $154bn.
