The recent rains that washed through West Africa didn’t fall just on one country. They caused severe flooding and fatalities across Nigeria, Cameroon, Chad, Mali and Niger.
The drought that came before this latest disaster didn’t single out one place either. Farmers across the region were faced with destitution from crop losses.
Extreme weather fuelled by climate change does not respect national borders or geographical boundaries. This simple fact has multiple knock-on effects and dictates how we should respond to such crises – including through international coordination.
In September, Nigeria’s Alau Dam collapsed as a result of floods in the country’s northeastern region, killing up to 1,000 people and displacing a million. The rupture of the dam was mainly due to poor maintenance over the years – and a government failure to heed warnings of danger.
A week later, across the border in Cameroon, the government there decided to release water from the Lagdo dam, after the same bout of heavy rainfall had increased levels. This put added pressure on 11 states downstream in the part of Nigeria that was already scrambling to deal with the crisis – although the water releases were regulated, and alerts were issued.
Nepal says China withholds “essential” info on bursting Himalayan glacial lakes
South Asia is also grappling with cross-border river-related threats. Izabella Koziell, deputy director general of ICIMOD, a Nepal-based research centre working to protect the Hindu Kush Himalaya, said the mountain region is “falling under increasing risk from the triple planetary crisis of climate change, biodiversity loss and air pollution”.
“Each of these risks are mobile and not limited by national borders,” she said. The region extends over 3,500 kilometres from Afghanistan to Myanmar, making cooperation between countries essential, she added. “Over two billion people living within the mountains and downstream will be affected by changes that happen here.”
Shared prosperity
Climate change is fuelling new and complex risks that require countries – and the international community – to look beyond their own borders and siloes. But that is not how governments and their partners have typically responded to the threats.
“Adaptation is still very much seen as a local to national issue. Thinking more broadly and working regionally is challenging. We saw this with the COVID-19 pandemic – just how difficult it was to get coordinated regional and global responses on something which affected everyone,” said Sarah Opitz-Stapleton, a senior research fellow at ODI Global, a London-based think-tank.
Opitz-Stapleton has been working with a research programme called “Supporting Pastoralism and Agriculture in Recurrent and Protracted Crises” (SPARC) to help policymakers better understand and manage transboundary climate risks, including in Africa.
She told Climate Home: “Countries tend to think first about their own sovereignty and protecting their own populations. This is understandable – but when we are facing challenges like this, everyone going in on their own is insufficient.”
Food and finance
People’s livelihoods and future prosperity are dependent on a globalised economy and shared resources, with flows of trade and finance binding countries together across continents. And it is becoming increasingly how clear how climate change – which affects the whole planet – can hijack development efforts in an interconnected world.
A simple example of this is food. In Senegal, changing dietary habits have led to a sudden surge in imports of rice from Southeast Asia. This now makes Senegal’s food security dependent on countries far away that are facing their own severe climate risks – because how they adapt to those risks will influence rice supplies to West Africa.
In 2022, India temporarily banned wheat exports after a severe heatwave jeopardised its own domestic supplies. The move led to a sudden jump in the price of this crucial commodity, impacting countries in Africa, such as Kenya, which rely on imports.
Transboundary climate risks come in many guises – from shared ecosystems to migration patterns, infectious diseases and ocean resources.
Finance is one example where the risks and impacts can be indirect and not always immediately clear. Financial firms are often greatly exposed to climate-related risks through investments in sectors from energy to mining.
When a gold mine is hit by drought or flooding, for example, this can lead to plant shutdowns, lower production and a higher probability of debt default.
Money is as transboundary as the climate. Banks that fail to carry out climate risk assessments across whole supply chains could be creating the conditions for stranded assets in the future.
Adaptation winners and losers
By focusing solely on how to adapt to issues within borders the problem is pushed into someone else’s backyard – the adaptation equivalent of whack-a-mole.
“The problem is the way we crafted the policy,” said George Wamukoya, team lead at AGNES, a non-profit which advises African governments on climate issues.
“We focused on ‘national’ adaptation plans and commitments which leads people to think inward. There is competition among neighbouring countries who don’t want to share resources or investment. This is despite the need for regional and global support to achieve these plans. We need to be alive to these facts,” he added.
Examples abound of so-called “maladaptation”. This can occur when a country seeks to control coastal erosion and flooding by building protective infrastructure but ends up pushing the problem to shorelines further away where the impacts might be worse. Or switching to climate-resilient crops can reduce harvests – and increase prices – for more mainstream varieties.
Global adaptation goal
On the other hand, done right, adaptation can lead to shared resilience between neighbours and strengthen global supply chains. Instead of redistributing the risk, the idea is to confront it with collaboration.
As the world kicks off two weeks of climate negotiations in Baku next week, campaigners are hoping that transboundary risks are higher on the agenda.
Last year’s UN climate summit, COP28, made only two references to transboundary issues in its final decision text. New work on adaptation did come out of the Dubai talks, including a programme to develop indicators to measure progress on targets under the Global Goal on Adaptation.
So far, the two-year initiative – called the UAE-Belem work programme – has led to over 5,000 indicators being submitted for consideration. Yet only 22 of these are related to transboundary climate risks.
This speaks to a lack of awareness among states of the shared risks they face and the dangers of ignoring them. Both Kenya and Ethiopia – which share a border that is porous especially for pastoralist communities – failed to mention cross-border risks in their national adaptation plans (NAPs) submitted to the UN.
Ensuring that transboundary risks are included in the UAE-Belem work programme is seen as crucial, as its results will dictate how adaptation policy and finance are set in the future. “If we don’t have these indicators, then it becomes very hard to track these particular risks,” said Wamukoya.
COP29 and beyond
Experts agree that national and local governments need to do a better job of assessing cross-border risks and working with their neighbours to understand how to collectively address them. To date, they feel that not enough work has been done to research transboundary risks and work out strategies for tackling them.
“We need to demystify the issue for countries and convince them that, when you include transboundary issues, this will not limit access to resources. We also need to show how and where these risks are occurring within the five subregions of Africa, because some places will be more exposed than others,” adds Wamukoya.
COP29 offers a unique forum to address transboundary risks that are global in nature – and this perspective also needs to be applied to finance for adaptation projects, where multiple countries are involved, Wamukoya said. COP29 is tasked with agreeing a new global goal for climate finance, he noted.
Rich nations “on track” to double adaptation finance but huge gap persists
To date, adaptation financing typically goes to a single country, and there are few mechanisms for allowing funding to be split across states – although the Green Climate Fund has taken a regional approach in some of its projects.
Opitz-Stapleton – who is helping organise several COP29 events on transboundary climate risks at the Climate, Peace and Transboundary Climate Pavilion, the first such COP pavilion – noted that awareness of the issue has grown.
But, she said, “many countries are not adequately assessing these risks and there isn’t capacity to manage them”. “They need to be incorporated within a country’s adaptation plans and actually acted on,” she emphasised.

DeBriefed 15 August 2025: Raging wildfires; Xi’s priorities; Factchecking the Trump climate report
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Blazing heat hits Europe
FANNING THE FLAMES: Wildfires “fanned by a heatwave and strong winds” caused havoc across southern Europe, Reuters reported. It added: “Fire has affected nearly 440,000 hectares (1,700 square miles) in the eurozone so far in 2025, double the average for the same period of the year since 2006.” Extreme heat is “breaking temperature records across Europe”, the Guardian said, with several countries reporting readings of around 40C.
HUMAN TOLL: At least three people have died in the wildfires erupting across Spain, Turkey and Albania, France24 said, adding that the fires have “displaced thousands in Greece and Albania”. Le Monde reported that a child in Italy “died of heatstroke”, while thousands were evacuated from Spain and firefighters “battled three large wildfires” in Portugal.
UK WILDFIRE RISK: The UK saw temperatures as high as 33.4C this week as England “entered its fourth heatwave”, BBC News said. The high heat is causing “nationally significant” water shortfalls, it added, “hitting farms, damaging wildlife and increasing wildfires”. The Daily Mirror noted that these conditions “could last until mid-autumn”. Scientists warn the UK faces possible “firewaves” due to climate change, BBC News also reported.
Around the world
- GRID PRESSURES: Iraq suffered a “near nationwide blackout” as elevated power demand – due to extreme temperatures of around 50C – triggered a transmission line failure, Bloomberg reported.
- ‘DIRE’ DOWN UNDER: The Australian government is keeping a climate risk assessment that contains “dire” implications for the continent “under wraps”, the Australian Financial Review said.
- EXTREME RAINFALL: Mexico City is “seeing one of its heaviest rainy seasons in years”, the Washington Post said. Downpours in the Japanese island of Kyushu “caused flooding and mudslides”, according to Politico. In Kashmir, flash floods killed 56 and left “scores missing”, the Associated Press said.
- SOUTH-SOUTH COOPERATION: China and Brazil agreed to “ensure the success” of COP30 in a recent phone call, Chinese state news agency Xinhua reported.
- PLASTIC ‘DEADLOCK’: Talks on a plastic pollution treaty have failed again at a summit in Geneva, according to the Guardian, with countries “deadlocked” on whether it should include “curbs on production and toxic chemicals”.

Factchecking Trump’s climate report
A report commissioned by the US government to justify rolling back climate regulations contains “at least 100 false or misleading statements”, according to a Carbon Brief factcheck involving dozens of leading climate scientists. The report, compiled in two months by five hand-picked researchers, inaccurately claims that “CO2-induced warming might be less damaging economically than commonly believed” and misleadingly states that “excessively aggressive [emissions] mitigation policies could prove more detrimental than beneficial”80
Spotlight
Does Xi Jinping care about climate change?
This week, Carbon Brief unpacks new research on Chinese president Xi Jinping’s policy priorities.
On this day in 2005, Xi Jinping, a local official in eastern China, made an unplanned speech when touring a small village – a rare occurrence in China’s highly-choreographed political culture.
In it, he observed that “lucid waters and lush mountains are mountains of silver and gold” – that is, the environment cannot be sacrificed for the sake of growth.
(The full text of the speech is not available, although Xi discussed the concept in a brief newspaper column – see below – a few days later.)
In a time where most government officials were laser-focused on delivering economic growth, this message was highly unusual.
Forward-thinking on environment
As a local official in the early 2000s, Xi endorsed the concept of “green GDP”, which integrates the value of natural resources and the environment into GDP calculations.
He also penned a regular newspaper column, 22 of which discussed environmental protection – although “climate change” was never mentioned.
This focus carried over to China’s national agenda when Xi became president.
New research from the Asia Society Policy Institute tracked policies in which Xi is reported by state media to have “personally” taken action.
It found that environmental protection is one of six topics in which he is often said to have directly steered policymaking.
Such policies include guidelines to build a “Beautiful China”, the creation of an environmental protection inspection team and the “three-north shelterbelt” afforestation programme.
“It’s important to know what Xi’s priorities are because the top leader wields outsized influence in the Chinese political system,” Neil Thomas, Asia Society Policy Institute fellow and report co-author, told Carbon Brief.
Local policymakers are “more likely” to invest resources in addressing policies they know have Xi’s attention, to increase their chances for promotion, he added.
What about climate and energy?
However, the research noted, climate and energy policies have not been publicised as bearing Xi’s personal touch.
“I think Xi prioritises environmental protection more than climate change because reducing pollution is an issue of social stability,” Thomas said, noting that “smoggy skies and polluted rivers” were more visible and more likely to trigger civil society pushback than gradual temperature increases.
The paper also said topics might not be linked to Xi personally when they are “too technical” or “politically sensitive”.
For example, Xi’s landmark decision for China to achieve carbon neutrality by 2060 is widely reported as having only been made after climate modelling – facilitated by former climate envoy Xie Zhenhua – showed that this goal was achievable.
Prior to this, Xi had never spoken publicly about carbon neutrality.
Prof Alex Wang, a University of California, Los Angeles professor of law not involved in the research, noted that emphasising Xi’s personal attention may signal “top” political priorities, but not necessarily Xi’s “personal interests”.
By not emphasising climate, he said, Xi may be trying to avoid “pushing the system to overprioritise climate to the exclusion of the other priorities”.
There are other ways to know where climate ranks on the policy agenda, Thomas noted:
“Climate watchers should look at what Xi says, what Xi does and what policies Xi authorises in the name of the ‘central committee’. Is Xi talking more about climate? Is Xi establishing institutions and convening meetings that focus on climate? Is climate becoming a more prominent theme in top-level documents?”

New York Already Denied Permits to These Gas Pipelines. Under Trump, They Could Get Greenlit
The specter of a “gas-for-wind” compromise between the governor and the White House is drawing the ire of residents as a deadline looms.
Hundreds of New Yorkers rallied against new natural gas pipelines in their state as a deadline loomed for the public to comment on a revived proposal to expand the gas pipeline that supplies downstate New York.
New York Already Denied Permits to These Gas Pipelines. Under Trump, They Could Get Greenlit
A “critical assessment” report commissioned by the Trump administration to justify a rollback of US climate regulations contains at least 100 false or misleading statements, according to a Carbon Brief factcheck involving dozens of leading climate scientists.
The report – “A critical review of impacts of greenhouse gas emissions on the US climate” – was published by the US Department of Energy (DoE) on 23 July, just days before the government laid out plans to revoke a scientific finding used as the legal basis for emissions regulation.
The executive summary of the controversial report inaccurately claims that “CO2-induced warming might be less damaging economically than commonly believed”.
It also states misleadingly that “excessively aggressive [emissions] mitigation policies could prove more detrimental than beneficial”.
Compiled in just two months by five “independent” researchers hand-selected by the climate-sceptic US secretary of energy Chris Wright, the document has sparked fierce criticism from climate scientists, who have pointed to factual errors, misrepresentation of research, messy citations and the cherry-picking of data.
Experts have also noted the authors’ track record of promoting views at odds with the mainstream understanding of climate science.
Wright’s department claims the report – which is currently open to public comment as part of a 30-day review – underwent an “internal peer-review period amongst [the] DoE’s scientific research community”.
The report is designed to provide a scientific underpinning to one flank of the Trump administration’s plans to rescind a finding that serves as the legal prerequisite for federal emissions regulation. (The second flank is about legal authority to regulate emissions.)
The “endangerment finding” – enacted by the Obama administration in 2009 – states that six greenhouse gases are contributing to the net-negative impacts of climate change and, thus, put the public in danger.
In a press release on 29 July, the US Environmental Protection Agency said “updated studies and information” set out in the new report would “challenge the assumptions” of the 2009 finding.
Carbon Brief asked a wide range of climate scientists, including those cited in the “critical review” itself, to factcheck the report’s various claims and statements.
