Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Drought in southern Africa
NATIONAL DISASTERS: An ongoing extreme drought in southern Africa is threatening millions of people with hunger, Sky News reported. According to Reuters, Zimbabwe has declared the drought a national disaster. The drought has also reached crisis levels in neighbouring Zambia and Malawi, with both countries declaring national disasters, the Associated Press said. Botswana, Angola, Mozambique and Madagascar are also affected, it added.
EL-NIÑO: Dry weather conditions linked to the El Niño weather pattern have worsened the drought, which emerged in its latest phase in mid-2023, Deutsche Welle reported. El Niño reached a peak in December, according to the World Meteorological Organization, but is still expected to result in above-normal temperatures until May, the outlet added. Scientists told Sky News that El Niño could be “amplifying the existing impacts of climate change”.
CALL FOR AID: Zimbabwe president Emmerson Mnangagwa said the country needs more than $2bn in aid to feed the millions of people facing hunger, the Associated Press reported. It added that the United Nations’ World Food Programme has already rolled out a food assistance programme targeting 2.7 million people.
Electric car sales slump
POOR QUARTER: The world’s top sellers of electric vehicles (EV), Elon Musk’s Tesla and Chinese rival BYD, reported sharp falls in sales in the first financial quarter of this year, adding to “concerns over the slowing shifts towards EVs”, the Financial Times reported. It added that both carmakers have repeatedly cut prices since the start of the year in a bid to stimulate demand.
DIRE FUTURE?: Tesla’s shares fell following the news, extending their 2024 slide to 33%, the second-worst showing in the S&P 500 stock market index, Bloomberg reported. The dip in sales comes amid a “sharp deterioration in growth” for US EVs, the New York Times said. However, Musk is mulling over the possibility of building a £3bn Tesla EV factory in India, the Daily Telegraph reported.
ELECTRIC SUBSIDIES: Only seven out of 500,000 EV charging stations have been built under a $7.5bn US government subsidy programme launched in 2021 and scheduled for completion by 2030, the Independent reported. The Federal Highway Administration told the Independent that “the slow pace has been deliberate, to avoid costly mistakes while navigating a brand-new law and building a network from scratch”.
Around the world
- SEARING HEAT: India’s national weather service has forecast “hotter-than-usual” temperatures for April to June, raising the risk of water shortages and crop damages, Bloomberg reported.
- UNUSUAL FIRES: Venezuela is battling a record number of wildfires – with satellites detecting more than 30,200 fires between January and March – as a climate change-driven drought consumes the Amazon rainforest region, according to Reuters.
- CLIMATE JUSTICE: Shell began its appeal against a ruling at The Hague that compelled it to slash its emissions by 45% by 2030, relative to 2019, the Financial Times reported. A judgement is expected in the second half of this year, the paper added.
- AID BY FOSSIL: White House officials have suggested that they are open to ending president Joe Biden’s pause on approvals of new liquefied natural gas (LNG) export terminals in order to get a Ukraine aid package through Congress, Reuters reported. A White House spokesperson denied the story.
- WARNING BELLS: According to a new study reported by the Guardian, a boom in mining projects for minerals needed in renewable energy technologies is now threatening up to a third of apes in Africa.
- STANDING TALL: A new analysis found that the number of trees lost in Brazil and Colombia was down “dramatically” in 2023 – falling by 39% – largely due to changes in political leadership in these nations, according to BBC News.
57
The number of fossil fuel and cement producers responsible for 80% of the world’s CO2 emissions from 2016-2022, according to the Carbon Majors project by non-profit thinktank InfluenceMap.
Latest climate research
- A study in npj Climate Action evaluated the perceptions of climate change among a selection of academics at a local university in Cameroon and suggested a framework to support educators as they help to foster critical thinking.
- The optimal location for North American birds has shifted northward by an average rate of 1.5km each year in response to climate change, a new study in Proceedings of the National Academy of Sciences found, representing a total distance moved of 82.5km over the past 55 years.
- A new study in Climate and Development investigated the “policy blind spots” around the contribution of women to rangeland cultivation in Tunisia and the effects of climate change on their livelihoods.

Captured
The UN climate change body, the UNFCCC, is largely funded by industrialised nations, such as the US, China, Japan, UK and France. However, these nations have not yet paid anything towards the UNFCCC’s core budget for this year, according to Carbon Brief analysis of UN data. This shortfall could be impacting the body’s functioning. For example, the UNFCCC recently cancelled this year’s Regional Climate Weeks, which are a “vital platform to express the concerns of people and communities most affected by climate change,” according to a comment piece by WaterAid’s Dulce Marrumbe published on Climate Home News. “The suspension of the Regional Climate Weeks is hugely disappointing news,” Marrumbe said.
Spotlight
How is Nigeria coping with extreme heat fuelled by climate change?
This week, Carbon Brief zooms in on how Nigerians are responding to the extreme heat affecting west Africa.
Since the start of this year, Africa’s most populous nation Nigeria has faced prolonged stretches of severe heat.
A recent quick-fire analysis found that the conditions in February, when temperatures exceeded 40C, were made 10 times more likely by human-caused climate change.
But the heat is still ongoing, with temperatures reaching a record 44.8C in Sokoto, a city in north-western Nigeria, on 1 April.
With comprehensive record-keeping of heat and its impacts lacking in Nigeria, Carbon Brief spoke to doctors, farmers and meteorologists about how this episode of extreme weather is affecting the country.
Health impacts
The impact of the heat is “catastrophic”, Dr Ugo Uguwanyi, a doctor in Abuja, Nigeria’s capital city, told Carbon Brief:
“Don’t even bother to step out from 10am to 6pm. And make sure you burn the diesel to power the air conditioning to be able to sleep at night.”
Information about the heatwave’s impact is limited, but this does not mean the weather conditions are not dangerous, according to the authors of the recent analysis into the role of climate change in Nigeria’s extreme heat. Rather, a lack of systematic reporting may obscure what they described as a “silent killer”.
In mid-February, the Nigerian Meteorological Agency (NiMet) issued a public forecast warning on the prolonged heatwave.
The agency advised citizens to stay hydrated, wear light clothing and avoid direct exposure to high temperatures during peak periods. A group of Nigerian doctors also issued safety tips.
NiMet’s director of Weather Forecast Services, Vincent Weli, had advised that a state of emergency be declared in states most affected by the heatwave and workers be allowed to take breaks between noon and 3pm. Speaking to Nigeria’s Channels Television, Weli said:
“Of course, you know, with high temperature, cognitive development will be affected and productivity will be affected. There will be a loss of concentration.”
However, no such directive has yet been issued by state governments.
Agricultural and workforce impacts
Meanwhile, in Lagos, Nigeria’s most populated city, ride-hailing drivers are operating under melting conditions, stuck between preserving their health or livelihood, according to a Rest of World report.
The heatwave is also expected to reduce agricultural productivity, a sector that contributes about 22% to Nigeria’s gross domestic product (GDP) and accounts for more than a third of total employment.
Wasiu Adeniyi Ibrahim, a meteorologist from NiMet, told Carbon Brief:
“Heatwaves can reduce agricultural productivity by causing heat stress to crops and livestock.”
There is not a lot of data on how the current heat is affecting agriculture in Nigeria.
However, the national secretary of the All Farmers Association of Nigeria, Yunusa Halidu, told Carbon Brief that its members expect the heatwave to affect productivity yield this year. He said:
“The heat is extreme this year, although we have been expecting it, as we work with the Nigerian Meteorological Agency. We know it is global warming and we are working to see how we can mitigate the effects.”

The post DeBriefed 5 April 2024: Southern Africa’s drought ‘disaster’; Top electric car sales slump; Is Nigeria coping with extreme heat? appeared first on Carbon Brief.
Al-Karim Govindji is the global head of public affairs for energy systems at DNV, an independent assurance and risk management provider, operating in more than 100 countries.
Optimism that this year may be less eventful than those that have preceded it have already been dealt a big blow – and we’re just weeks into 2026. Events in Venezuela, protests in Iran and a potential diplomatic crisis over Greenland all spell a continuation of the unpredictability that has now become the norm.
As is so often the case, it is impossible to separate energy and the industry that provides it from the geopolitical incidents shaping the future. Increasingly we hear the phrase ‘the past is a foreign country’, but for those working in oil and gas, offshore wind, and everything in between, this sentiment rings truer every day. More than 10 years on from the signing of the Paris Agreement, the sector and the world around it is unrecognisable.
The decade has, to date, been defined by a gritty reality – geopolitical friction, trade barriers and shifting domestic priorities – and amidst policy reversals in major economies, it is tempting to conclude that the transition is stalling.
Truth, however, is so often found in the numbers – and DNV’s Energy Transition Outlook 2025 should act as a tonic for those feeling downhearted about the state of play.
While the transition is becoming more fragmented and slower than required, it is being propelled by a new, powerful logic found at the intersection between national energy security and unbeatable renewable economics.
A diverging global trajectory
The transition is no longer a single, uniform movement; rather, we are seeing a widening “execution gap” between mature technologies and those still finding their feet. Driven by China’s massive industrial scaling, solar PV, onshore wind and battery storage have reached a price point where they are virtually unstoppable.
These variable renewables are projected to account for 32% of global power by 2030, surging to over half of the world’s electricity by 2040. This shift signals the end of coal and gas dominance, with the fossil fuel share of the power sector expected to collapse from 59% today to just 4% by 2060.

Climate at Davos: Energy security in the geopolitical driving seat
While climate change is a lower priority for leaders at this year’s World Economic Forum, control of energy supplies and minerals is a hot topic
Conversely, technologies that require heavy subsidies or consistent long-term policy, the likes of hydrogen derivatives (ammonia and methanol), floating wind and carbon capture, are struggling to gain traction.
Our forecast for hydrogen’s share in the 2050 energy mix has been downgraded from 4.8% to 3.5% over the last three years, as large-scale commercialisation for these “hard-to-abate” solutions is pushed back into the 2040s.
Regional friction and the security paradigm
Policy volatility remains a significant risk to transition timelines across the globe, most notably in North America. Recently we have seen the US pivot its policy to favour fossil fuel promotion, something that is only likely to increase under the current administration.
Invariably this creates measurable drag, with our research suggesting the region will emit 500-1,000 Mt more CO₂ annually through 2050 than previously projected.
China, conversely, continues to shatter energy transition records, installing over half of the world’s solar and 60% of its wind capacity.
In Europe and Asia, energy policy is increasingly viewed through the lens of sovereignty; renewables are no longer just ‘green’, they are ‘domestic’, ‘indigenous’, ‘homegrown’. They offer a way to reduce reliance on volatile international fuel markets and protect industrial competitiveness.
Grids and the AI variable
As we move toward a future where electricity’s share of energy demand doubles to 43% by 2060, we are hitting a physical wall, namely the power grid.
In Europe, this ‘gridlock’ is already a much-discussed issue and without faster infrastructure expansion, wind and solar deployment will be constrained by 8% and 16% respectively by 2035.

This pressure is compounded by the rise of Artificial Intelligence (AI). While AI will represent only 3% of global electricity use by 2040, its concentration in North American data centres means it will consume a staggering 12% of the region’s power demand.
This localized hunger for power threatens to slow the retirement of fossil fuel plants as utilities struggle to meet surging base-load requirements.
The offshore resurgence
Despite recent headlines regarding supply chain inflation and project cancellations, the long-term outlook for offshore energy remains robust.
We anticipate a strong resurgence post-2030 as costs stabilise and supply chains mature, positioning offshore wind as a central pillar of energy-secure systems.
Governments defend clean energy transition as US snubs renewables agency
A new trend is also emerging in behind-the-meter offshore power, where hybrid floating platforms that combine wind and solar will power subsea operations and maritime hubs, effectively bypassing grid bottlenecks while decarbonising oil and gas infrastructure.
2.2C – a reality check
Global CO₂ emissions are finally expected to have peaked in 2025, but the descent will be gradual.
On our current path, the 1.5C carbon budget will be exhausted by 2029, leading the world toward 2.2C of warming by the end of the century.
Still, the transition is not failing – but it is changing shape, moving away from a policy-led “green dream” toward a market-led “industrial reality”.
For the ocean and energy sectors, the strategy for the next decade is clear. Scale the technologies that are winning today, aggressively unblock the infrastructure bottlenecks of tomorrow, and plan for a future that will, once again, look wholly different.

Post-COP 30 Modeling Shows World Is Far Off Track for Climate Goals
The head of the United Nations body governing the global shipping industry has said that greenhouse gases from the global shipping industry will fall, whether or not the sector’s “Net Zero Framework” to cut emissions is adopted in October.
Arsenio Dominguez, secretary-general of the International Maritime Organization, told a new year’s press conference in London on Friday that, even if governments don’t sign up to the framework later this year as planned, the clean-up of the industry responsible for 3% of global emissions will continue.
“I reiterate my call to industry that the decarbonisation has started. There’s lots of research and development that is ongoing. There’s new plans on alternative fuels like methanol and ammonia that continue to evolve,” he told journalists.
He said he has not heard any government dispute a set of decarbonisation goals agreed in 2023. These include targets to reduce emissions 20-30% on 2008 levels by 2030 and then to reach net zero emissions “by or around, i.e. close to 2050”.

US-led alliance wins a year’s delay in adoption of green shipping deal
The IMO’s Net-Zero Framework will be up for approval again in October 2026, after the US and Saudi Arabia persuaded countries not to vote on it as planned -

A treaty to protect the high seas entered into force this week with the backing of over 80 countries including late ratifications by Japan, China and Brazil
Dominguez said the 2030 emissions reduction target could be reached, although a goal for shipping to use at least 5% clean fuels by 2030 would be difficult to meet because their cost will remain high until at least the 2030s. The goals agreed in 2023 also included cutting emissions by 70-80% by 2040.
In October 2025, a decision on a proposed framework of practical measures to achieve the goals, which aims to incentivise shipowners to go green by taxing polluting ships and subsidising cleaner ones, was postponed by a year after a narrow vote by governments.
Ahead of that vote, the US threatened governments and their officials with sanctions, tariffs and visa restrictions – and President Donald Trump called the framework a “Green New Scam Tax on Shipping”.
Dominguez said at Friday’s press conference that he had not received any official complaints about the US’s behaviour at last October’s meeting but – without naming names – he called on nations to be “more respectful” at the IMO. He added that he did not think the US would leave the IMO, saying Washington had engaged constructively on the organisation’s budget and plans.
EU urged to clarify ETS position
The European Union – along with Brazil and Pacific island nations – pushed hard for the framework to be adopted in October. Some developing countries were concerned that the EU would retain its charges for polluting ships under its emissions trading scheme (ETS), even if the Net Zero Framework was passed, leading to ships travelling to and from the EU being charged twice.
This was an uncertainty that the US and Saudi Arabia exploited at the meeting to try and win over wavering developing countries. Most African, Asian and Caribbean nations voted for a delay.
On Friday, Dominguez called on the EU “to clarify their position on the review of the ETS, in order that as we move forward, we actually don’t have two systems that are going to be basically looking for the same the same goal, the same objective.”
He said he would continue to speak to EU member states, “to maintain the conversations in here, rather than move forward into fragmentation, because that will have a very detrimental effect in shipping”. “That would really create difficulties for operators, that would increase the cost, and everybody’s going to suffer from it,” he added.
The IMO’s marine environment protection committee, in which governments discuss climate strategy, will meet in April although the Net Zero Framework is not scheduled to be officially discussed until October.
