The veteran climate envoys from the world’s two biggest polluters have stepped down in the same week, creating uncertainty at the top of international climate talks.
After suffering health problems, 74-year-old Xie Zhenhua Chinese climate envoy resigned earlier this month and will be replaced by foreign ministry diplomat Liu Zhenmin.
The same week this news broke, 80-year-old John Kerry told US President Joe Biden that he would step down as climate envoy in the next few months. He will campaign for Biden to win the presidential election in November. His replacement is unknown.
With the European Union appointing a new top climate diplomat last year and holding elections in June, all three of the world’s biggest polluters will be led by relatively new faces at Cop29 in November.
US-China ties
Xie has led China’s climate diplomacy for most of the period since 2007 while Kerry was heavily involved in climate talks as Barack Obama’s foreign minister and Biden’s climate envoy.
The two have a close personal relationship, shown most recently by Xie bringing his grandchildren to Cop28 in Dubai to sing happy birthday to Kerry. Xie’s return from retirement in 2021 was widely interpreted as a response to Kerry’s appointment.

They have attempted to keep US-China climate talks going despite wider geopolitical tensions, particularly over China’s relationship with Taiwan.
The two sides are now talking about cooperation on issues like methane, clean electricity and urban climate action. But the outcome of US elections later this year could scupper talks.
China’s climate lead
Xie was appointed vice chair of China’s top economic planning body in 2007 and put in charge of climate talks. He was in the post until 2020 when he briefly retired before being re-appointed in 2021.
Former US negotiator Todd Stern described him in 2019 as a steadfast defender of Chinese interests who was likable, cared about climate change and wanted to get things done.

Over his tenure, China has become more proactive about wanting to tackle climate change. It has set a net zero goal, established a carbon market, become a renewable energy leader and pledged to stop financing new coal power overseas – although it still plans to build many new coal plants.
Xie oversaw secret work to model different pathways for China to reach net zero emissions – models that eventually informed President Xi Jinping’s aim to reach carbon neutrality by 2060.
He suffered what Kerry called “something of a stroke” in January 2023 which prevented him from working and travelling abroad for much of this year, although he did lead China at Cop28 in Dubai.
The new boss
His replacement Liu previously worked for the United Nations as one of its second-highest ranking officials, focussing on economic and social affairs.
Before that, he was an ambassador to the United Nations in Geneva and then China’s deputy foreign minister and worked on the Paris and Kyoto climate agreements.

One China climate watcher, who did not want to be named, told Climate Home that many experts wanted someone from the environment ministry appointed not someone like Liu from the foreign service.
“To oversimplify,” they said, the”[foreign ministry] approaches climate as a card in U.S.-China grand bargain” whereas the “environment [ministry] sees climate change as a real issue that needs to be solved”. The foreign ministry “is known to be conservative and inaccessible”, they added.
On the other hand, the source said that Liu was “probably the most familiar with climate issues in China’s foreign service”.
Chatham House analyst Bernice Lee said, “sure, he is not from the environment ministry but no doubt he will be a fast learner not just in substance but also the building of an international network”. She described him as a “diplomat”, adding “challenging times require someone with diplomatic skills”.
Big hitter gone
After rising up as a Vietnam war veteran, senator and failed presidential candidate, Kerry was appointed as Barack Obama’s secretary of state in 2013.
Kerry worked with Xie to agree on carbon-cutting deals between the two nations which helped land the Paris Agreement in 2015. He went on to sign it with his granddaughter on his lap the next year.

Kerry left office when Donald Trump was elected in 2016. He came back into the fold immediately after the election of Joe Biden, who chose him as a presidential envoy on climate change. Kerry led the US delegation at Cop26, Cop27 and Cop28.
Jake Schmidt, from the Natural Resources Defence Council, said Kerry “helped rally the world around a commitment to transition away from fossil fuels, speed the growth of clean energy, and begin to mobilise resources to help the world’s most vulnerable nations cope with the consequences of the climate crisis”.
Kerry’s successor is unknown. His two deputies are Rick Duke and Sue Biniaz. If Donald Trump wins the presidential election in November, he is unlikely to appoint a climate envoy.

Europe has been hit by a searing heatwave, which has shattered temperature records across France, Spain and the UK.
In London, for example, the mercury hit a record high for May of 35.1C at Kew Gardens on Tuesday 26 May, breaking the former record-high May temperature by more than 2C.
Multiple people have died as a result of the high temperatures, including 14 people across the UK and France who drowned.
The heatwave was driven by a “heat dome”, in which warm air moving up from northern Africa has become trapped under a high-pressure system over western Europe.
Experts have been quick to point out the link between extreme heat and global warming, with one saying it was “beyond a shadow of a doubt” that climate change was making such events “more likely and more severe”.
In this article, Carbon Brief examines the impacts of the heatwave and the role of climate change.

What is happening with the May heatwave in Europe?
Europe has been hit by “mind-bogglingly crazy” temperature records in May, according to the Financial Times, quoting Peter Thorne, director of the ICARUS Climate Research Centre at Maynooth University in Ireland.
In London, on Tuesday 26 May, temperatures hit a record high for May of 35.1C at Kew Gardens – breaking the previous record of 34.8C, set just the day before.
This was more than 2C above the previous May temperature high of 32.8C recorded in 1922 and again in 1944, reported the Times.
The Associated Press added that the UK capital also recorded a rare “tropical night”, when temperatures did not fall below 20C overnight.
The Daily Telegraph reported that Wales and Northern Ireland also saw record-high temperatures, of 27.4C in Cardiff and 23.4C in Armagh, on Sunday.
As with the UK record, these were quickly surpassed. BBC News reported that temperatures hit 32.9C in Bute Park, Cardiff and 24.5C in Thomastown, County Fermanagh, on Tuesday.
BBC News quoted a spokesperson from the Met Office, who said:
“This heat would be exceptional in the UK even in mid-summer, let alone in May.”
The broadcaster added that the average temperature in the UK at the end of May is usually 14-20C.
The Associated Press reported that temperature records have also fallen across Europe.
This includes in France, where temperatures reached 36C on Monday in the country’s south-west and remained above 20C at night across much of the country. The newspaper Libération declared that “it has never been so hot, so early, in France”.
The Guardian reported that the weather agency Météo France said the heatwave could last through the week and bring temperatures as high as 39C in some areas in the country.
As well as the UK and France, other nations have been seeing temperatures soar. France24 reported that temperatures in Spain were expected to reach 38C, with Italy also facing high temperatures.
The Irish Times reported that the May high-temperature record was broken twice in Ireland on the same day, with 29.7C recorded in Carlow and then 30.5C at Shannon Airport on Tuesday.
Le Monde explained that a “heat dome” of warm air from northern Africa is behind the high temperatures across Europe. (See: What is driving the record-breaking heat?)
The Financial Times quoted ICARUS’s Thorne saying that the records being set in Europe, “particularly in the UK and France, are mind-bogglingly crazy”. He added:
“We have more than 100 years of observational records. To break the all-time May record by more than 2C…is hard to comprehend.”
What is driving the record-shattering heat?
The immediate driver of the extreme heat seen over Europe this week is a “heat dome”, according to Politico.
The outlet explained that the phenomenon is driven by “warm air moving up from northern Africa [that] has become trapped under a high-pressure system over western Europe”. It added:
“The effect is similar to that of a lid on a pot, with warm air forced downward and baking affected regions with prolonged, blistering heat.”
Spain’s El Correo explained that the phenomenon is “not a simple heatwave”, adding that such “high-pressure systems trapped over Europe are not usually seen before summer”.
However, many publications have linked the severity of the extreme heat to climate change. The Associated Press quoted ICARUS’s Thorne, who said:
“We know beyond a shadow of a doubt that heatwave events such as this have been made more likely and more severe due to climate change arising from our emissions of heat-trapping greenhouse gases.”
The Guardian quoted Dr Chloe Brimicombe, a researcher at the University of Oxford, who said:
“The record-breaking heat is a reminder of how climate change is impacting our lives in the UK. It highlights the urgency of recent calls for heat adaptation.”
France’s Le Figaro described the event as an “unequivocal sign of global warming”.
The Independent reported that the heatwave “has the fingerprints of climate change all over it”. Other outlets, including Inside Climate News and Scientific American, also covered the links between extreme heat and climate change.
BBC News noted that over the last 30 years, Europe has been warming by 0.56C per decade – more than twice the global average.
The outlet quoted Prof Erich Fischer, professor at the Institute for Atmospheric and Climate Science at ETH Zurich in Switzerland, who compared the record-breaking temperatures to setting a new record in sports.
He explained that “if someone beats a world record in high jump, you would expect them to beat it by one centimetre and not suddenly by 20, 30 centimetres”. Similarly, he said that in the case of temperature, you would expect new records to be broken by a fraction of a degree, rather than 2 or 3C.
However, the broadcaster explained that “when a relatively rare weather system, such as this week’s heat dome, comes around in a warming climate, the margin of record can be huge”.
Simon Stiell, the executive secretary of UN Climate Change, called the heatwave a “brutal reminder of the cost of global warming”, according to Politico.
The Guardian also quotes Stiell, who said:
“The science is clear that human-induced climate change is making these heatwaves more frequent and extreme”.
What are the impacts of the extreme heat?
The heatwave has already been linked to multiple deaths.
This included seven people in France, five of whom died by drowning and two who suffered heat-related deaths while competing in sporting events, said the Guardian.
Separately, the Guardian reported that at least nine people have died in the UK from “water-related incidents” during the heatwave.
France24 reported that “restrictions on outdoor work were imposed in parts of Italy” and that “farmers reported accelerated harvests as temperatures went beyond 30C across [south-west France]”.
The Guardian reported that tennis players at the French Open were “forced to adjust their games while trying to find their best level through obvious discomfort”, amid 33C temperatures in Boulogne-Billancourt, Paris, on Monday.
CNN added that, in the UK, “a wildfire broke out near Arthur’s Seat, a hill in Edinburgh, Scotland, and hundreds of properties in south-east England were left without water as demand spiked”.
BBC News reported on a warning from a chief nurse that hospitals in the south-west of England were busier than usual amid the heatwave.
BBC News reported that the UK saw a surge in emergency calls on Tuesday. The Daily Telegraph added that “Britain’s roads started melting and rail commuters were left stranded for hours”.
Meanwhile, the Guardian reported on a warning from climate campaigners that the government “urgently” needs to start installing air conditioning units in schools and care homes.
The extreme heat has also affected Europe’s renewable energy generation. Bloomberg said that “the heat dome has blocked clouds and fueled booming solar generation”, but added that “by clearing clouds and calming the atmosphere, the heat dome has had the opposite effect on wind speeds”.
How has the media responded?
The unseasonably high temperatures have caught the attention of news outlets in the UK, France and other affected nations.
Often, news stories were accompanied by photos of people relaxing at the beach, eating ice cream and swimming in the sea.
Such images of “fun in the sun” have often drawn criticism from climate researchers for “misrepresenting” the risks of heatwaves.
This choice of imagery – and the way right-leaning newspapers in the UK tend to focus on the positive aspects of hot weather – was highlighted by journalist and media critic Mic Wright in a Substack post. He wrote:
“Most British newspapers write about extremely hot weather with the tone of a frog in a boiling pot pretending it’s a jacuzzi.”
Despite blanket news coverage of the record heat in media outlets across western Europe, there has been relatively little commentary from their opinion pages.
No major UK newspapers have published editorials about the heat and there has been no space dedicated to it in the comment sections of the largest French and Spanish newspapers.
One exception in UK media was the Daily Mail’s climate-sceptic columnist Richard Littlejohn writing an article mocking heat-safety measures and warnings issued by the Met Office and the UK Health Security Agency (UKHSA).
In contrast, the Guardian published an article by Bill McGuire, professor emeritus of geophysical and climate hazards at University College London, warning of the dangers facing the UK as extreme heat becomes “the norm”. He wrote:
“We need, then, to face the fact that life in the 2050s is going to be very different from today, and act now. The sooner we recognise this and begin – as a nation – to prepare and adapt accordingly, the better we will be able to meet these enormous challenges to our everyday lives.”
Oliver Duff, editor-in-chief of the i newspaper, wrote that the UK is “emotionally underprepared”, as a nation, for the heat:
“Worries about climate change are forgotten in the giddy determination to enjoy our brief, unreliable summers, whichever month of the year they deign to visit.”
Writing in the Independent, journalist Kat Brown reflected on the Climate Change Committee’s recent advice to the UK government on adapting to climate change. She stressed the need to “take heatwaves seriously”.
James Wallace, chief executive of the charity River Action, was given a guest column in the Daily Express in which he wrote: “As the nation swelters in record-breaking temperatures, England is sleepwalking into a water crisis.”
In reference to water shortages and increasingly extreme weather, Wallace also emphasised that “this is climate breakdown in real time”.

The odds of a new global temperature record being set within the next five years have increased further, as the return of the El Niño weather pattern could make 2027 the hottest year ever, the UN’s weather agency has warned.
The World Meteorological Organization (WMO)’s annual update predicts an 86% chance that at least one year between 2026 and 2030 will surpass 2024 as the warmest year on record – up from 80% in last year’s forecast.
Global average temperatures reached 1.55C above pre-industrial levels in 2024, when the last El Niño event supercharged human-made warming primarily caused by the greenhouse gas emissions generated through burning fossil fuels.
El Niño to supercharge heat in 2027
Meteorologists expect El Niño – the natural climate phenomenon characterised by unusually warm sea-surface temperatures in the eastern Pacific Ocean – to start developing as early as this month. Some forecasters say that this time around the event could become particularly powerful.
Leon Hermanson, the lead author of the WMO report, said the prediction of El Niño for the second half of 2026 “increases the chances of the following year, 2027, being the next record-breaking year”.
Researchers warn that a strong El Niño risks supercharging extreme weather conditions, contributing to more severe wildfires and droughts in some regions and storms and floods in others.
Scientists warn El Niño could intensify climate extremes in 2026
The UN agency says there is a 91% chance that the key 1.5C warming threshold will be temporarily exceeded again for at least one year between 2026 and 2030. An overshoot in a single year does not mean that the most ambitious global warming goal enshrined in the Paris Agreement has been lost. But the UN conceded last year that a “multi-decadal” breach is very likely to happen within the next decade.
‘Astonishing’ early heatwave in Europe
Western Europe has already been gripped by an early-season heatwave this month, with countries including the UK, France and Ireland recording their hottest May temperatures ever.
“Temperatures on this scale were once exceptional even at the height of summer,” said Friederike Otto, professor of climate science at Imperial College London. “Seeing 35C in the UK during spring is absolutely astonishing, but the science is very clear – climate change makes these heatwaves hotter, longer, and far more frequent”.
She added that “temperature records will continue to tumble until we fundamentally halt global emissions and reach net zero”.
In India, extreme heat in recent weeks has also threatened mango and other crops and pushed up power demand to an all-time high as people switch on air-conditioning, while pilgrims in Mecca have conducted their rituals during the annual Hajj pilgrimage in scorching temperatures.
