Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
Secrets and layoffs
UNLAWFUL PANEL: A federal judge ruled that the US energy department “violated the law when secretary Chris Wright handpicked five researchers who rejected the scientific consensus on climate change to work in secret on a sweeping government report on global warming”, reported the New York Times. The newspaper explained that a 1972 law “does not allow agencies to recruit or rely on secret groups for the purposes of policymaking”. A Carbon Brief factcheck found more than 100 false or misleading claims in the report.
DARKNESS DESCENDS: The Washington Post reportedly sent layoff notices to “at least 14” of its climate journalists, as part of a wider move from the newspaper’s billionaire owner, Jeff Bezos, to eliminate 300 jobs at the publication, claimed Climate Colored Goggles. After the layoffs, the newspaper will have five journalists left on its award-winning climate desk, according to the substack run by a former climate reporter at the Los Angeles Times. It comes after CBS News laid off most of its climate team in October, it added.
WIND UNBLOCKED: Elsewhere, a separate federal ruling said that a wind project off the coast of New York state can continue, which now means that “all five offshore wind projects halted by the Trump administration in December can resume construction”, said Reuters. Bloomberg added that “Ørsted said it has spent $7bn on the development, which is 45% complete”.
- CHANGING TIDES: The EU is “mulling a new strategy” in climate diplomacy after struggling to gather support for “faster, more ambitious action to cut planet-heating emissions” at last year’s UN climate summit COP30, reported Reuters.
- FINANCE ‘CUT’: The UK government is planning to cut climate finance by more than a fifth, from £11.6bn over the past five years to £9bn in the next five, according to the Guardian.
- BIG PLANS: India’s 2026 budget included a new $2.2bn funding push for carbon capture technologies, reported Carbon Brief. The budget also outlined support for renewables and the mining and processing of critical minerals.
- MOROCCO FLOODS: More than 140,000 people have been evacuated in Morocco as “heavy rainfall and water releases from overfilled dams led to flooding”, reported the Associated Press.
- CASHFLOW: “Flawed” economic models used by governments and financial bodies “ignor[e] shocks from extreme weather and climate tipping points”, posing the risk of a “global financial crash”, according to a Carbon Tracker report covered by the Guardian.
- HEATING UP: The International Olympic Committee is discussing options to hold future winter games earlier in the year “because of the effects of warmer temperatures”, said the Associated Press.

Solar power, electric vehicles and other clean-energy technologies drove more than a third of the growth in China’s economy in 2025 – and more than 90% of the rise in investment, according to new analysis for Carbon Brief (shown in blue above). Clean-energy sectors contributed a record 15.4tn yuan ($2.1tn) in 2025, some 11.4% of China’s gross domestic product (GDP) – comparable to the economies of Brazil or Canada, the analysis said.
Can humans reverse nature decline?
This week, Carbon Brief travelled to a UN event in Manchester, UK to speak to biodiversity scientists about the chances of reversing nature loss.
Officials from more than 150 countries arrived in Manchester this week to approve a new UN report on how nature underpins economic prosperity.
The meeting comes just four years before nations are due to meet a global target to halt and reverse biodiversity loss, agreed in 2022 under the landmark “Kunming-Montreal Global Biodiversity Framework” (GBF).
At the sidelines of the meeting, Carbon Brief spoke to a range of scientists about humanity’s chances of meeting the 2030 goal. Their answers have been edited for length and clarity.
Dr David Obura, ecologist and chair of Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)
We can’t halt and reverse the decline of every ecosystem. But we can try to “bend the curve” or halt and reverse the drivers of decline. That’s the economic drivers, the indirect drivers and the values shifts we need to have. What the GBF aspires to do, in terms of halting and reversing biodiversity loss, we can put in place the enabling drivers for that by 2030, but we won’t be able to do it fast enough at this point to halt [the loss] of all ecosystems.
Dr Luthando Dziba, executive secretary of IPBES
Countries are due to report on progress by the end of February this year on their national strategies to the Convention on Biological Diversity [CBD]. Once we get that, coupled with a process that is ongoing within the CBD, which is called the global stocktake, I think that’s going to give insights on progress as to whether this is possible to achieve by 2030…Are we on the right trajectory? I think we are and hopefully we will continue to move towards the final destination of having halted biodiversity loss, but also of living in harmony with nature.
Prof Laura Pereira, scientist at the Global Change Institute at Wits University, South Africa
At the global level, I think it’s very unlikely that we’re going to achieve the overall goal of halting biodiversity loss by 2030. That being said, I think we will make substantial inroads towards achieving our longer term targets. There is a lot of hope, but we’ve also got to be very aware that we have not necessarily seen the transformative changes that are going to be needed to really reverse the impacts on biodiversity.
Dr David Cooper, chair of the UK’s Joint Nature Conservation Committee and former executive secretary of the Convention on Biological Diversity
It’s important to look at the GBF as a whole…I think it is possible to achieve those targets, or at least most of them, and to make substantial progress towards them. It is possible, still, to take action to put nature on a path to recovery. We’ll have to increasingly look at the drivers.
Prof Andrew Gonzalez, McGill University professor and co-chair of an IPBES biodiversity monitoring assessment
I think for many of the 23 targets across the GBF, it’s going to be challenging to hit those by 2030. I think we’re looking at a process that’s starting now in earnest as countries [implement steps and measure progress]…You have to align efforts for conserving nature, the economics of protecting nature [and] the social dimensions of that, and who benefits, whose rights are preserved and protected.
Neville Ash, director of the UN Environment Programme World Conservation Monitoring Centre
The ambitions in the 2030 targets are very high, so it’s going to be a stretch for many governments to make the actions necessary to achieve those targets, but even if we make all the actions in the next four years, it doesn’t mean we halt and reverse biodiversity loss by 2030. It means we put the action in place to enable that to happen in the future…The important thing at this stage is the urgent action to address the loss of biodiversity, with the result of that finding its way through by the ambition of 2050 of living in harmony with nature.
Prof Pam McElwee, Rutgers University professor and co-chair of an IPBES “nexus assessment” report
If you look at all of the available evidence, it’s pretty clear that we’re going to keep experiencing biodiversity decline. I mean, it’s fairly similar to the 1.5C climate target. We are not going to meet that either. But that doesn’t mean that you slow down the ambition…even though you recognise that we probably won’t meet that specific timebound target, that’s all the more reason to continue to do what we’re doing and, in fact, accelerate action.
OIL IMPACTS: Gas flaring has risen in the Niger Delta since oil and gas major Shell sold its assets in the Nigerian “oil hub”, a Climate Home News investigation found.
LOW SNOW: The Washington Post explored how “climate change is making the Winter Olympics harder to host”.
