Methane on the rise
NEAR-RECORD LEVELS: Methane emissions from the fossil-fuel industry rose to near-record levels of 120m tonnes last year, “despite technology available to curb this pollution at virtually no cost”, according to Agence France-Presse. Reuters added that the high levels of methane emissions were produced despite commitments by companies and governments to plug leaking fossil-fuel infrastructure, according to the International Energy Agency’s (IEA) annual methane tracker report.
MORE METHANE: Separately, a new study in Nature concluded that US oil-and-gas infrastructure emits three times as much methane into the atmosphere as government estimates suggest, the Associated Press reported. According to New Scientist, the study was based on nearly one million aerial surveys of methane leaks, creating what one of the scientists described as “the largest such dataset that has ever been assembled”.
Europe’s climate risks
MAJOR SHOCKS: The European Environment Agency (EEA) has issued its first assessment of the “urgent” climate risks facing Europe, the Guardian reported. More action is needed to address half of the 36 significant climate risks, such as wildfires and other climate disasters, according to the report, the Guardian said. The Financial Times noted that, according to the EEA, the EU is at “higher and higher” risk of major financial shocks from climate change.
DECIMATED FARMING: Meanwhile, Politico reported that the European Commission is working on legislative proposals that would “severely weaken” environmental requirements for agricultural workers in the EU, amid ongoing farmers’ protests across the continent. This is despite advice by top EU scientists that agriculture “must become more sustainable or it will be decimated by climate change”, the article added.
Around the world
- ZAMBIA DROUGHT: More than one million people face food shortages and malnutrition in Zambia due to crop failures triggered by drought, according to an Oxfam report covered by Down To Earth. Much of southern Africa continued to face record temperatures.
- TRANSITIONING AWAY?: The US Export-Import Bank, a federal institution that finances projects overseas, has voted to put $500m toward an oil-and-gas project in Bahrain, according to the New York Times. It noted that this was viewed by critics as “out of step” with US pledges to move away from fossil fuels.
- SHELL BACKTRACKS: Oil giant Shell has weakened its emissions target for 2030 and dropped its goal for 2035 entirely, in an update to its “energy transition strategy”, Bloomberg reported. Carbon Brief explained the changes with charts.
- YOUTH AT RISK: Young activists, including climate campaigners, must be better protected from online attacks, arrests and physical threats, according to a report by UN special rapporteur on human rights defenders Mary Lawlor, covered by the Guardian.
- GAS BOOST: UK energy secretary Claire Coutinho announced plans to support new gas power plants, claiming that without them the country could face “blackouts”, the Press Association reported. Ministers later confirmed that unabated gas would still only meet around 1% of demand in 2035.
- ELECTRIC SWAP: Mexico’s parliament has agreed to amend the nation’s General Law on Climate Change to support programmes that facilitate the replacement of combustion-engine cars with electric and hybrid vehicles, according to Excélsior.
$1 trillion
The amount that India has asked developed countries to provide in climate finance each year from 2025 as a minimum to help developing countries deal with climate change, according to the Times of India.
Latest climate research
- New research in Nature estimated that global economic losses from heat stress could reach 0.6-4.6% by 2060. Major losses came from health impacts, lower labour productivity and disruptions to supply chains, the study found.
- Fears about Covid-19 reinforced climate change concerns rather than providing a distraction from the crisis, according to a new survey of 28 European countries published in Climate Risk Management.
- Newcastle University in the UK is asking members of the public to participate in a survey into “uncertainty distress” in relation to climate change.
Captured
New Carbon Brief analysis based on provisional government data showed that UK emissions fell to just 383m tonnes of carbon dioxide equivalent (MtCO2e) in 2023. This marked the first time emissions have fallen below 400MtCO2e since Victorian times. However, this drop was mostly unrelated to deliberate climate action by the government. Instead, much of it came about due to a drop in gas demand, driven by factors such as higher electricity imports from French nuclear plants and warmer temperatures. The analysis was covered by the Times and was the focus of an editorial.
Spotlight
‘Drill, baby, drill’: The history of Trump’s favourite slogan
Carbon Brief explores the history of a slogan claimed by Donald Trump, but with roots stretching back to Sarah Palin and, prior to this, the Black Panthers.
The senior Republican who first used the phrase tells Carbon Brief that he is critical of Trump and those who want to “drill with abandon” today.
In a recent interview with Fox News, former president Donald Trump summarised his plans for US fossil-fuel production if he wins the election this year, by saying:
“We are going to – I used this expression, now everyone else is using it so I hate to use it, but – drill, baby, drill.”
Despite Trump’s assertion, it was Michael Steele, the US politician who was the first African-American lieutenant governor of Maryland and chair of the Republican National Committee, who came up with the slogan
Addressing the 2008 Republican National Convention, he told the crowd:
“Let’s reduce our dependency on foreign sources of oil, and promote oil-and-gas production at home. Let me make it very clear: Drill, baby, drill, and drill now.”
Speaking to Carbon Brief, Steele said that the slogan came to him late at night, after a fit of “writer’s block”.
“Donald Trump…his BS aside, had nothing to do with ‘drill, baby drill’,” stressed Steele, who today is a staunch critic of the Republican presidential candidate.
The phrase was used by supporters throughout the campaign of Republican John McCain in his unsuccessful presidential bid against Barack Obama.
It became particularly associated with Sarah Palin, the climate-sceptic Republican vice-presidential pick, who said in a debate with her Democratic challenger Joe Biden:
“The chant is ‘drill, baby, drill’. And that’s what we hear all across this country in our rallies because people are so hungry for those domestic sources of energy.”
In the years that followed, the phrase was repeated endlessly by Republican politicians, as well as in comment articles and political analysis. (It did, however, see a dip in popularity following the Deepwater Horizon oil spill in 2010.)
There was some bemusement at a slogan that appeared to have been derived from “burn, baby, burn”.
That phrase, which has since made its way into everything from disco songs to hot sauce, was originally associated with Black nationalist group the Black Panthers and particularly the 1965 Watts riots in Los Angeles. It was chanted as buildings were set on fire, amid civil unrest sparked by police violence against an African-American man.
Writing shortly after the Republican National Convention in 2008, journalist Derrick Z Jackson alluded to this when he wrote in the Boston Globe:
“This 93% White gathering blithely stole from the race riots of the ’60s to lustily chant ‘drill, baby, drill’.”
For his part, Steele told Carbon Brief that his intention was to use a colloquial expression to “connect it to something that was very real” – namely, cutting US reliance on Middle Eastern oil. He said:
“Unfortunately, a lot of people use it…in a way that they don’t fully appreciate what the point was, and the point was the self-sufficiency of the American spirit.”
He added that “it’s not just ‘drill with abandon’, it’s also the idea of drilling responsibly”, noting that, with the growth of electric cars and other technologies in the US:
“‘Drill, baby, drill’ may at some point in the future change to…‘plug, baby, plug’.”
Nevertheless, Steele accepted that while he will “always be there to remind [Trump]” of where the slogan came from, it is out of his hands now:
“My only regret is that I didn’t copyright it and put it on a T-shirt.”
Watch, read, listen
‘OIL COLONIALISM’: The latest episode of the Drilled podcast explored how Nigerians are “resisting oil colonialism” after Shell announced at the end of 2023 that it was shutting down its onshore operations in the country.
CLIMATE PLOTTERS: An article in Sierra examined what it called a “conspiracy to take down wind and solar power” across the US, made up of “climate-science deniers, right-wing think tanks and fossil fuel shills”.
KYOTO ON STAGE: The Royal Shakespeare Company in Stratford-upon-Avon, UK, is putting on a production of Kyoto, a play that dramatises the UN climate summit in 1997 that gave rise to the Kyoto Protocol.

The post DeBriefed 15 March 2024: Global methane surge; Europe faces ‘urgent’ climate risks; Surprising origin of Trump’s ‘drill, baby, drill’ appeared first on Carbon Brief.
Drought and heatwaves occurring together – known as “compound” events – have “surged” across the world since the early 2000s, a new study shows.
Compound drought and heat events (CDHEs) can have devastating effects, creating the ideal conditions for intense wildfires, such as Australia’s “Black Summer” of 2019-20 where bushfires burned 24m hectares and killed 33 people.
The research, published in Science Advances, finds that the increase in CDHEs is predominantly being driven by events that start with a heatwave.
The global area affected by such “heatwave-led” compound events has more than doubled between 1980-2001 and 2002-23, the study says.
The rapid increase in these events over the last 23 years cannot be explained solely by global warming, the authors note.
Since the late 1990s, feedbacks between the land and the atmosphere have become stronger, making heatwaves more likely to trigger drought conditions, they explain.
One of the study authors tells Carbon Brief that societies must pay greater attention to compound events, which can “cause severe impacts on ecosystems, agriculture and society”.
Compound events
CDHEs are extreme weather events where drought and heatwave conditions occur simultaneously – or shortly after each other – in the same region.
These events are often triggered by large-scale weather patterns, such as “blocking” highs, which can produce “prolonged” hot and dry conditions, according to the study.
Prof Sang-Wook Yeh is one of the study authors and a professor at the Ewha Womans University in South Korea. He tells Carbon Brief:
“When heatwaves and droughts occur together, the two hazards reinforce each other through land-atmosphere interactions. This amplifies surface heating and soil moisture deficits, making compound events more intense and damaging than single hazards.”
CDHEs can begin with either a heatwave or a drought.
The sequence of these extremes is important, the study says, as they have different drivers and impacts.
For example, in a CDHE where the heatwave was the precursor, increased direct sunshine causes more moisture loss from soils and plants, leading to a drought.
Conversely, in an event where the drought was the precursor, the lack of soil moisture means that less of the sun’s energy goes into evaporation and more goes into warming the Earth’s surface. This produces favourable conditions for heatwaves.
The study shows that the majority of CDHEs globally start out as a drought.
In recent years, there has been increasing focus on these events due to the devastating impact they have on agriculture, ecosystems and public health.
In Russia in the summer of 2010, a compound drought-heatwave event – and the associated wildfires – caused the death of nearly 55,000 people, the study notes.
The record-breaking Pacific north-west “heat dome” in 2021 triggered extreme drought conditions that caused “significant declines” in wheat yields, as well as in barley, canola and fruit production in British Columbia and Alberta, Canada, says the study.
Increasing events
To assess how CDHEs are changing, the researchers use daily reanalysis data to identify droughts and heatwaves events. (Reanalysis data combines past observations with climate models to create a historical climate record.) Then, using an algorithm, they analyse how these events overlap in both time and space.
The study covers the period from 1980 to 2023 and the world’s land surface, excluding polar regions where CDHEs are rare.
The research finds that the area of land affected by CDHEs has “increased substantially” since the early 2000s.
Heatwave-led events have been the main contributor to this increase, the study says, with their spatial extent rising 110% between 1980-2001 and 2002-23, compared to a 59% increase for drought-led events.
The map below shows the global distribution of CDHEs over 1980-2023. The charts show the percentage of the land surface affected by a heatwave-led CDHE (red) or a drought-led CDHE (yellow) in a given year (left) and relative increase in each CDHE type (right).
The study finds that CDHEs have occurred most frequently in northern South America, the southern US, eastern Europe, central Africa and south Asia.
Threshold passed
The authors explain that the increase in heatwave-led CDHEs is related to rising global temperatures, but that this does not tell the whole story.
In the earlier 22-year period of 1980-2001, the study finds that the spatial extent of heatwave-led CDHEs rises by 1.6% per 1C of global temperature rise. For the more-recent period of 2022-23, this increases “nearly eightfold” to 13.1%.
The change suggests that the rapid increase in the heatwave-led CDHEs occurred after the global average temperature “surpasse[d] a certain temperature threshold”, the paper says.
This threshold is an absolute global average temperature of 14.3C, the authors estimate (based on an 11-year average), which the world passed around the year 2000.
Investigating the recent surge in heatwave-leading CDHEs further, the researchers find a “regime shift” in land-atmosphere dynamics “toward a persistently intensified state after the late 1990s”.
In other words, the way that drier soils drive higher surface temperatures, and vice versa, is becoming stronger, resulting in more heatwave-led compound events.
Daily data
The research has some advantages over other previous studies, Yeh says. For instance, the new work uses daily estimations of CDHEs, compared to monthly data used in past research. This is “important for capturing the detailed occurrence” of these events, says Yeh.
He adds that another advantage of their study is that it distinguishes the sequence of droughts and heatwaves, which allows them to “better understand the differences” in the characteristics of CDHEs.
Dr Meryem Tanarhte is a climate scientist at the University Hassan II in Morocco, and Dr Ruth Cerezo Mota is a climatologist and a researcher at the National Autonomous University of Mexico. Both scientists, who were not involved in the study, agree that the daily estimations give a clearer picture of how CDHEs are changing.
Cerezo-Mota adds that another major contribution of the study is its global focus. She tells Carbon Brief that in some regions, such as Mexico and Africa, there is a lack of studies on CDHEs:
“Not because the events do not occur, but perhaps because [these regions] do not have all the data or the expertise to do so.”
However, she notes that the reanalysis data used by the study does have limitations with how it represents rainfall in some parts of the world.
Compound impacts
The study notes that if CDHEs continue to intensify – particularly events where heatwaves are the precursors – they could drive declining crop productivity, increased wildfire frequency and severe public health crises.
These impacts could be “much more rapid and severe as global warming continues”, Yeh tells Carbon Brief.
Tanarhte notes that these events can be forecasted up to 10 days ahead in many regions. Furthermore, she says, the strongest impacts can be prevented “through preparedness and adaptation”, including through “water management for agriculture, heatwave mitigation measures and wildfire mitigation”.
The study recommends reassessing current risk management strategies for these compound events. It also suggests incorporating the sequences of drought and heatwaves into compound event analysis frameworks “to enhance climate risk management”.
Cerezo-Mota says that it is clear that the world needs to be prepared for the increased occurrence of these events. She tells Carbon Brief:
“These [risk assessments and strategies] need to be carried out at the local level to understand the complexities of each region.”

DeBriefed 6 March 2026: Iran energy crisis | China climate plan | Bristol’s ‘pioneering’ wind turbine
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Energy crisis
ENERGY SPIKE: US-Israeli attacks on Iran and subsequent counterattacks across the Middle East have sent energy prices “soaring”, according to Reuters. The newswire reported that the region “accounts for just under a third of global oil production and almost a fifth of gas”. The Guardian noted that shipping traffic through the strait of Hormuz, which normally ferries 20% of the world’s oil, “all but ground to a halt”. The Financial Times reported that attacks by Iran on Middle East energy facilities – notably in Qatar – triggered the “biggest rise in gas prices since Russia’s full-scale invasion of Ukraine”.
‘RISK’ AND ‘BENEFITS’: Bloomberg reported on increases in diesel prices in Europe and the US, speculating that rising fuel costs could be “a risk for president Donald Trump”. US gas producers are “poised to benefit from the big disruption in global supply”, according to CNBC. Indian government sources told the
