Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
UK parliament’s climate takeover
MILIBAND SPEECH: UK energy security and net-zero secretary Ed Miliband delivered a “scathing” address to parliament on the “state of the climate and nature” in the UK, Edie reported. Ahead of his speech, Miliband told the Guardian he intends it to become an annual event, adding: “I feel a deep sense of responsibility to the British people to tell them the truth about what we know about the climate and nature crisis.”
RENEWABLES ‘BOOST’: Elsewhere, the government unveiled a strategy for “longer clean power contracts”, reported BusinessGreen, with the aim of “boost[ing] investor confidence” and “curb[ing] consumer costs”. It said the government will amend its “contracts for difference scheme” (CfD), raising contract duration from 15 to 20 years. Carbon Brief’s Simon Evans provided more details.
REFORM U-TURN: The Financial Times reported that the hard-right Reform UK party wrote a letter to “green energy bosses” threatening to “strike down” renewable energy subsidies and “reassess all net-zero related commitments” due to “intolerable costs to the economy”, if successful in the next election. However, deputy leader Richard Tice appeared to backtrack just 24 hours later in an interview with BBC Radio 4’s PM, claiming the letter had been “misread” and that a “contract is a contract”.
Around the world
- NASA DATA: In the US, the Trump administration aborted plans to publish major climate change reports on NASA’s website, the Associated Press reported. This will “make it harder to find major, legally mandated assessments of how climate change is endangering the nation and its people”, the newswire added.
- ‘LANDMARK’ BATTLE: The Australian government has no obligation to protect Torres Strait islanders from the impacts of climate change, concluded a major federal case covered by BBC News. It added that the verdict left community leaders “in shock”.
- ‘FAIR COMPETITION’: The European Union seeks “fair competition” with China on clean energy, Agence France-Press said. However, “tensions are high” ahead of an upcoming summit in Beijing on 24 July, according to the Economist, with electric vehicles a “particular crunch point”.
- MONSOON DEATHS: More than 60 people were killed in 24 hours in ongoing torrential monsoon rains in Pakistan, the nation’s Dawn newspaper reported.
- CANCELLED CELEBRATIONS: Traditional Bastille Day celebrations were cancelled across France due to the risk of fire amid extreme temperatures, Le Monde reported.

Captured
India has reached a milestone of 50% of its installed electricity capacity coming from “non-fossil fuel” sources (renewables and nuclear) – ahead of its 2030 target under the Paris Agreement, Reuters reported. The newswire said the move “signal[s] accelerating momentum in the country’s clean-energy transition”. A press release from India’s Ministry of New and Renewable Energy stated that, “despite having one of the lowest per-capita emissions globally, India remains among the few G20 countries that are on track to meet – or even exceed – their NDC commitments”. The research group Climate Action Tracker rates India’s climate pledges as “highly insufficient“.
Spotlight
‘Climate justice and cultural survival’ in Kenya
This week, Carbon Brief interviews Julianna Loshiro, an Indigenous Yaaku activist working in Kenya to conserve nature and her native language.
Carbon Brief: Can you explain who you are, where you come from and the projects you work on?
Julianna Loshiro: I’m a proud Yaaku woman from Mukogodo Forest, north in Laikipia, Kenya, where our language, Yaakunte, and way of life have been passed down through generations. Raised by my grandparents, I was immersed in Indigenous knowledge systems.
Living in the forest is a struggle because of land insecurity. Evictions have been happening to the Ogiek of Mau, the Sengwer community from Cherangany, and even the Yaaku community.
Currently, I am leading efforts to revitalise the Yakuunte language through storytelling, theatre, curriculum development and digital tools. My work is driven by a commitment to cultural resilience and intergenerational justice.
CB: You’ve recently published a book, “Climate Justice is Gender Justice”. Could you outline the key messages that you are trying to get across and also what motivated you to write the book?
JL: My book is an extension of our ancestral wisdom. Every chapter echoes the values and land-based knowledge that I grew up with in the Mukogodo forest. It is an urgent call to centre Indigenous knowledge in the climate conversation and to understand justice through the lens of lived experience. I wrote this book to amplify the stories and wisdom that often go unheard, especially from rural Indigenous communities.
One of the key ideas I share is that climate solutions are not just scientific, they are also cultural, emotional and relational. The book reflects how climate change impacts everyday lives and how different genders experience this crisis differently, but it also shows how we can heal by listening to those closest to the land.
Writing the book was a way of sharing our Yaaku worldview with the wider world, where nature is family and language is spirit. Culture is a form of resistance. So, by linking climate justice with our cultural survival, I am showing that language and environmental conservation are deeply intertwined. If we lose one, we risk losing the other. This book is a living testimony that our Indigenous identity is key to the future of our planet.
CB: Your book promotion also references the organisation, Indigenous Young Moms, for which you serve as project manager. What perspectives does motherhood lend to efforts to achieve both climate and gender justice?
JL: Motherhood sharpens our sense of urgency and hope. As an indigenous young mother, I don’t just see climate change in statistics, I see it in the drying rivers, the struggling bees and the questions my child will ask tomorrow.
Climate justice is gender justice because it demands that we account for these differences. It means dismantling systems that exclude women, men, non-binary and gender-diverse people from decisions, and it is Indigenous women who often lead the way.
CB: What has been missing from the conversation around preserving Indigenous cultural heritage and empowering Indigenous communities? How do you see your book filling this gap?
JL: Indigenous systems are too often ignored in development efforts. As a Yaaku woman, I have felt the silence imposed on both my language and my gender. We need to create solutions led by Indigenous people. We must be trusted as experts and storytellers in this journey.
Now, it is young people bringing positive and impactful solutions, at the grassroots level, and to even bigger platforms, like speaking at Indigenous caucuses. We’re really happy to see individuals and organisations holding out their hands to us. It’s really moving because it’s been hard for our voices to be heard.

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 Economic Times that Russia is prepared to “fulfil India’s energy demands”. China Daily quoted experts who said “China’s energy security remains fundamentally unshaken”, thanks to “emergency stockpiles and a wide array of import channels”.
‘ESSENTIAL’ RENEWABLES: Energy analysts said governments should cut their fossil-fuel reliance by investing in renewables, “rather than just seeking non-Gulf oil and gas suppliers”, reported Climate Home News. This message was echoed by UK business secretary Peter Kyle, who said “doubling down on renewables” was “essential” amid “regional instability”, according to the Daily Telegraph.
China’s climate plan
PEAK COAL?: China has set out its next “five-year plan” at the annual “two sessions” meeting of the National People’s Congress, including its climate strategy out to 2030, according to the Hong Kong-based South China Morning Post. The plan called for China to cut its carbon emissions per unit of gross domestic product (GDP) by 17% from 2026 to 2030, which “may allow for continued increase in emissions given the rate of GDP growth”, reported Reuters. The newswire added that the plan also had targets to reach peak coal in the next five years and replace 30m tonnes per year of coal with renewables.
ACTIVE YET PRUDENT: Bloomberg described the new plan as “cautious”, stating that it “frustrat[es] hopes for tighter policy that would drive the nation to peak carbon emissions well before president Xi Jinping’s 2030 deadline”. Carbon Brief has just published an in-depth analysis of the plan. China Daily reported that the strategy “highlights measures to promote the climate targets of peaking carbon dioxide emissions before 2030”, which China said it would work towards “actively yet prudently”.
Around the world
- EU RULES: The European Commission has proposed new “made in Europe” rules to support domestic low-carbon industries, “against fierce competition from China”, reported
