On Sunday, Mexicans chose Claudia Sheinbaum as their new leader – blazing a trail not just by electing the country’s first female president but also by putting a climate scientist at the helm of a major nation.
Sheinbaum, an energy engineer who worked unpaid on two major reports issued by the Intergovernmental Panel on Climate Change (IPCC), will take control of the world’s 14th biggest economy on December 1, for a term due to last until 2030.
While IPCC climate scientists have been appointed as environment ministers in countries like Chile and Egypt, Climate Home was unable to identify any who have served as a national leader.
As Sheinbaum courted votes across the country of 127 million grappling with a drought, heatwave and smog, she promised to invest nearly $14 billion in clean energy and boost electric buses and trains.
“We have to speed up the promotion of renewable energies,” she told a group of Mexican businessmen in April. “We are working on the national energy plan not only through 2030, but to 2050”.
Deep scepticism
But some fellow Mexican climate scientists and political analysts told Climate Home they were sceptical about whether she will deliver on her green promises.
They criticised her record as mayor of Mexico City, a position she held from 2018 to 2023, and said her climate ambition would be held back by her close ties to current pro-fossil fuel President Andrés Manuel López Obrador (known as AMLO) and her ideological aversion to private-sector energy.

Political risk analyst Carlos Ramirez, a partner at Integralia Consultants, told Climate Home that “there is no question that her commitment to climate change is real”, adding “that is a welcome shift from what we have seen so far [under the current government]”.
But, he said, “there will be López Obrador ghosts haunting her – his legacy will mean that she cannot move much from what we are seeing now, and the people who surround him will be watching her closely.”
If she did opt for bigger green changes, “she would have to pay a political price for that,” he noted. “So far she has not given any evidence that she will do so.”
Emissions expert
Sheinbaum grew up in Mexico City with scientists for parents. She signed up to study physics herself, earning undergraduate and masters degrees at the National Autonomous University of Mexico (UNAM).
In the early 1990s, she spent four years at the Lawrence Berkeley National Laboratory in California, doing a PhD on energy emissions and environmental problems in Mexico City’s transport sector before joining UNAM’s staff.

Following a stint as the environment secretary of then Mexico City Mayor López Obrador, she returned to UNAM and helped write the emissions reduction sections of the flagship IPCC assessment reports in 2007 and 2014. Her research on Mexican manufacturing and cement emissions was cited and – like all IPCC authors – she worked long hours unpaid.
Mexico City Mayor
Sheinbaum then went back into politics with López Obrador’s new left-wing party MORENA and was selected as its candidate for mayor of Mexico City in 2018, a position she held until she resigned last year in order to run for the national presidency.
As mayor, she promoted solar power. But UNAM climate scientist Ruth Cerezo-Mota said she had seen no sign of Sheinbaum attempting to solve the city’s serious air pollution problem.
Another UNAM climate scientist, Xochitl Cruz Núñez, who worked with Sheinbaum on the IPCC’s fifth assessment report, told Climate Home that Sheinbaum’s climate work as mayor was “minimal”.

Cruz Núñez criticised the city’s diesel-powered bus system, water scarcity and increased urbanisation under Sheinbaum’s leadership, saying it had caused “uncontrolled” construction in surrounding conservation areas.
AMLO’s legacy
Mexico previously enjoyed a reputation as a front-runner on climate action, passing one of the developing world’s earliest climate change laws in 2012. But some of that progress was reversed during López Obrador’s presidency.
The outgoing president dismantled climate policies and institutions and promoted energy sovereignty through domestic fossil fuel production, putting power back into the hands of state-owned companies: electricity utility CFE and oil and gas giant PEMEX.
His government invested billions of dollars into oil and gas infrastructure, and blocked private investment into renewables. Today, Mexico is one of only two G20 countries without a net zero emissions target and has watered down its 2030 emissions reduction goal.
Sheinbaum became MORENA’s candidate for the presidency largely because of López Obrador’s support for her, winning the national election on Sunday partly thanks to his track record as the country’s most popular modern president.

Political analyst Ramirez said Sheinbaum’s political alignment with López Obrador hinders the chances of her pursuing more ambitious climate action.
“Sheinbaum is speaking loudly about bringing renewables back into the system but at the same time – and here is where the problems begin – she wants to give continuity to the energy policy of López Obrador,” he said.
“She has a strong ideological view that [state-owned] CFE and PEMEX should lead the energy transition,” he added. “This is a contradiction. I think it will be a very slow process and eventually fail.”
Cruz Núñez noted that Sheinbaum intends to maintain state stewardship over oil and electricity, while mobilising public resources for renewables, but questioned whether this alone could work. “My opinion is that private investment is required if renewable energy is to be introduced at the level needed for Mexico to fulfill its promises under the Paris Agreement,” she added.
Despite her alliance with AMLO, Sheinbaum has disagreed with him in the past. During the Covid-19 pandemic, for example, she promoted mask-wearing, testing and vaccinations in Mexico City while the president played down the risks.
Cruz Núñez expressed hope that, having won the election, Sheinbaum will take advantage of her new independence from López Obrador to establish a clear programme for cutting Mexico’s emissions and adapting to climate change.
“I believe she knows enough about climate change and the need to solve it,” she added.

Mexico elects a climate scientist as president – but will politics temper her green ambition?
CANBERRA, Monday 27 October 2025 — More than 100 Australian scientists and researchers have called on the Labor Government to address deforestation in the new nature law reforms, warning that the impacts under the current Act “compound the damage caused by repeated mass bleaching events driven by climate change” to the Great Barrier Reef.
Environment Minister Murray Watt will soon table the draft bill to reform Australia’s broken nature law, the Environment Protection and Biodiversity Conservation (EPBC) Act. Leading environmental groups Greenpeace Australia Pacific, the Australian Marine Conservation Society, and the Australian Conservation Foundation coordinated the open letter with 112 leading Australian scientists, calling for the reforms to close loopholes in the Act that allow for rampant and unchecked deforestation, especially in the Great Barrier Reef catchment.
Read the letter here.
Elle Lawless, senior campaigner at Greenpeace Australia Pacific, said:
“Now is the time to act decisively for nature, and design a nature-first nature law that will do what it is set out to do: protect our environment. Toxic runoff from deforestation in the Great Barrier Reef catchment is poisoning the reef and suffocating the precious and fragile marine ecosystem. The Great Barrier Reef is a global icon, and we need a strong, robust EPBC Act that will safeguard and protect it. This is one of the most important pieces of legislation our country and our environment has and, done right, has the power to make serious and desperately needed positive changes to protect nature.”
Professor James Watson FQA, from UQ’s School of the Environment, said:
“Australia’s State of the Environment report, released by the federal government in 2021, shows that our oceans, rivers and wetlands are in serious decline. That report, and the Samuel review of the EPBC, make the point that there is a desperate need for stronger national nature laws that help protect these precious places for generations to come.
“Australia’s top environmental academics and experts have been sounding the alarm for decades: the large-scale destruction of Australia’s native woodlands, forests, wetlands and grasslands is the single biggest threat to our biodiversity. It’s driving an extinction crisis unlike anywhere else on Earth — and it’s threatening the Great Barrier Reef, one of the world’s seven natural wonders, right before our eyes.”
Continued mass deforestation threatens the Great Barrier Reef’s World Heritage status. In 2026, the World Heritage Committee will review Australia’s progress in protecting the reef and may consider placing it on the World Heritage in Danger list if major threats like deforestation are not addressed.
Recent figures from the Queensland Government show deforestation in Queensland is the worst in the nation and worsening under the current national environment law. Deforestation in the Great Barrier Reef catchment accounted for almost half (44%) of the state’s total clearing, an increase on the previous year.
Greenpeace Australia Pacific is calling for the EPBC reforms to meet four key tests:
- Stronger upfront nature protection to guide better decisions on big projects, including National Environmental Standards.
- An independent Environmental Protection Agency (EPA) to enforce the laws and make decisions about controversial projects at arm’s length from politics.
- Closing deforestation loopholes that allow for harmful industries to carry out mass bulldozing across Australia.
- Consideration of the climate impacts on nature from coal and gas mines when assessing projects for approvals.
“We will continue to engage with the government constructively in the reform process but also hold decision-makers to account over these critical tests,” Lawless said.

Leading scientists call for EPBC reforms to strengthen Great Barrier Reef protection
22 October 2025
The Hon Anthony Albanese MP
Prime Minister
Parliament House
CANBERRA ACT 2600
Sent via email
To the Prime Minister, Federal Environment Minister, and Members of the Albanese Government,
As researchers who study, document and work to recover Australia’s plants and animals, insects and ecosystems, we are keenly aware of the value of nature to Australians and the world.
Australia has one of the worst rates of deforestation globally. For every 100 hectares of native woodland cleared, about 2000 birds, 15,000 reptiles and 500 native mammals will die. As scientists and experts, we have sounded the alarm for more than 30 years that the large-scale destruction of native woodlands, forests, wetlands and grasslands was the single biggest threat to the nation’s biodiversity. That is still the case today, and it is driving an extinction crisis.
New figures show that Queensland continues to lead the nation in deforestation. The latest statewide landcover and trees study (SLATS) report shows that annually 44% of all deforestation in Queensland occurs in the Great Barrier Reef catchment areas, where over 140,000 hectares are bulldozed each year.
Deforestation in Great Barrier Reef catchments is devastating one of Australia’s most iconic natural wonders. When forests and bushland are bulldozed, erosion causes debris to wash into waterways, sending sediment, nutrients and pesticides into the Reef waters. This smothers coral, fuels crown-of-thorns starfish outbreaks, and reduces water quality. These impacts compound the damage caused by repeated mass bleaching events driven by climate change.
The Great Barrier Reef sustains precious marine life, supports local and global biodiversity, and underpins tourism economies and coastal communities that rely on its survival. Continued mass deforestation threatens these values and could jeopardise the Reef’s World Heritage status. In 2026 the World Heritage Committee will review Australia’s progress in protecting the Reef and may consider placing it on the World Heritage in Danger list, if key threats to the Reef, including deforestation, are not addressed.
This mass deforestation happens due to a loophole in the Environment Protection and Biodiversity Conservation (EPBC) Act, our national nature law. Exemptions allow deforestation to continue largely unregulated by the EPBC Act through a grandfathering clause from 2000 known as “continuous use”. Without meaningful reform, deforestation will continue to drive massive biodiversity loss. This loophole must be closed as part of the proposed EPBC Act reforms. The law is meant to safeguard our wildlife and our most precious places like the Great Barrier Reef. Please support closing major deforestation loopholes in the EPBC Act as an urgent and priority issue for the Federal Government.

The recent discovery of Grimpoteuthis feitiana, a new species of Dumbo octopus found deep in the Pacific, is a reminder of something both humbling and urgent: we still know so little about the ocean that shapes our lives. This fragile, finned creature, gliding silently more than a kilometer beneath the waves, has lived in these waters long before we mapped them, and its story is only now coming to light.
What moves me most about this discovery is not just the Dumbo octopus itself, but how it bridges science and culture. Its name draws inspiration from the flying apsaras of China’s Dunhuang murals, those graceful, winged figures that seem to dance through air and imagination. It reminds me that the deep sea has always held a place in our collective human story, — not only in myths and art, but in the ways we relate to nature, learn from it, and find meaning within it.
Pasifika connection to the ocean
For us in the Pacific, the ocean is more than a body of water. It is our identity, our culture, our history. Our ancestors read the seas to navigate, to survive, to connect communities scattered across islands. Discoveries like this Dumbo octopus awaken something deeper in me, — a sense that the ocean is alive with stories and wisdom we are only beginning to rediscover. And with that understanding comes a responsibility to protect it.
Each new species like the Dumbo octopus, each glimpse into the deep, is a warning as much as it is a wonder. The creatures of the abyss live slow, deliberate lives in fragile ecosystems, shaped by balance and patience. Deep-sea mining, pollution, and climate change threaten to erase them before we even learn their names. Protecting the Pacific’s oceans is not an abstract act of conservation; it is an act of cultural preservation, of love for our home, and for the unseen life that sustains us all.
Grimpoteuthis feitiana is more than a scientific discovery. It is a reminder that the ocean is still full of life, mystery, and wisdom — and that we have a duty to ensure these depths remain wild, healthy, and alive, for us and for the generations yet to come.
