Amazon summit leaves observers ‘frustrated’
MISSING THE TARGET: The fifth summit of the Amazon Cooperation Treaty Organization (ACTO) took place last Friday, with the release of the Bogotá Declaration coming the next day, Agência Brasil reported. The meeting was a “platform to update the commitments of the countries” that share the Amazon rainforest, the outlet said. The declaration “emphasised the urgency of coordinated action against deforestation and biodiversity loss”, but there was an “absence of clearer targets”, which “frustrated” observers and civil-society groups. Agência Brasil also said that the “issue of energy transition and fossil-fuel exploration” was divisive at the summit.

INDIGENOUS INCLUSION: Ahead of the meeting, Indigenous groups were “demanding that oil be left underground…[and] that the Amazon be declared the world’s first no-go zone for fossil-fuel exploration and exploitation”, EFE Verde reported. According to Stand.earth, the summit “strengthen[ed] Indigenous participation” despite “fail[ing]” to meet the fossil-fuel demands. The summit resulted in the creation of the Amazonian Indigenous Peoples Mechanism (MAPI), which Stand.earth explained “establishes a co-governance structure” for ACTO where each country is represented by both a government and an Indigenous delegate.
FUND THE FACILITY: Another element of the Bogotá Declaration was a pledge to support the Tropical Forests Forever Facility (TFFF), Climate Home News reported. The outlet added that the declaration “invites” countries to “announce substantial contributions” in order to “guarantee the fund’s quick activation”. Brazil’s president, Luiz Inácio Lula da Silva, said: “We’re fed up with promises…I want to see who’s going to put up the money to keep the forest standing.” Meanwhile, ((o))eco reported that Brazil saw an 84% increase in international climate finance from 2019-20 to 2021-22, but forests received just 2%.
Wildfires continue to burn
NEW EU RECORD: Wildfires have ravaged more than 1m hectares in the EU in 2025, the largest area since records began in 2006, according to an analysis by Agence France-Presse. The news agency analysed data from the European Forest Fire Information System and found that Spain, Cyprus, Germany and Slovakia have been the hardest hit over the past two decades. Additionally, satellites revealed that wildfires across the Iberian peninsula released 13m tonnes of carbon dioxide this year – six times larger than 2022 levels, El Periódico reported.
HARDEST HIT: Six firefighters died while combatting “devastating wildfires exacerbated by an enduring heatwave” in Spain and Portugal, according to France24. More than 343,000 hectares were “ravage[d]” this year in Spain, setting a new national record, the outlet said. Scientists identified the primary cause of the fires in both countries as an “overabundance of flammable vegetation on abandoned land and authorities’ failure to take preventive measures,” which prompted Spain’s environmental prosecutor to initiate an “investigation into the lack of prevention plans”, Politico added.
US FIRES: Wildfires in California and Oregon led to the evacuation of thousands of homes, the Associated Press reported. In Oregon, the fire began Thursday and “grew quickly amid hot, gusty conditions”, the newswire said. A “sweltering” heatwave has hospitalised people in the western US, it added. Mongabay covered the “scientific standoff” surrounding the “active management” of forests, which consists of using controlled burning and thinning of forests to promote regeneration and resilience. It added that forest managers are “grappl[ing] with the growing effects of climate change”.
PRIVATE SECTOR CALL: Nature loss will reduce UK GDP by 5% without a “greater effort” from the private sector to halt the decline, the Guardian said. A report from the Green Finance Institute and WWF said that companies in many sectors can receive economic returns from investment in nature. The outlet noted that some businesses “are failing to reform or are unaware of the impact of their actions on nature and the climate”. The report listed suggestions for companies to take action on nature decline.
SOLAR SLOWDOWN: The US Department of Agriculture (USDA) announced it will “heighten scrutiny of some solar and wind projects” on farmland across the country, reported Reuters. The agency said it will stop funding larger renewable energy facilities and will not allow the use of foreign-made solar panels. Inside Climate News said the agency had expressed concern about the possible expansion of wind and solar facilities on productive farmland. However, the outlet cited a 2024 USDA analysis finding that renewables occupy 0.05% of the 897m acres of pasture and cropland in the country.
FISHERY REFORM: Ghanaian president John Dramani Mahama signed a “sweeping” fisheries and aquaculture reform act into law last week that the government believes will “ensure sustainability…and better protection for the country’s fishing communities”, according to Ghana Broadcasting Corporation. One provision in the bill is an expansion of the country’s inshore exclusion zone, which prevents industrial trawling ships from encroaching on artisanal fishing grounds. News Ghana reported that the law is “designed to address EU trade sanctions”, which threaten the country’s $425m annual seafood exports.
POLARISED POLICY: A new forest land policy in the Philippines has been touted by officials as a “major shift in forest governance”, but has been questioned by civil society organisations, Mongabay reported. Under the policy, farmers are able to carry out multiple different land uses – including reforestation, ecotourism, conservation and commercial use – in designated forest areas. The secretary of the Philippines’s environment department said the reform is an attempt to “unlock the economic potential” of the country’s forests and scale up sustainable investment. The outlet said that environmental groups warned of the policy resulting in forest degradation, the displacement of Indigenous peoples and greenwashing.
PARAGUAYAN PLANTATIONS: Apple purchased carbon credits associated with the use of agrochemicals harmful to communities on eucalyptus plantations in Paraguay, a joint investigation for Consenso and Climate Tracker revealed. The investigation used documents, field visits and satellite images to show that the forestry company selling these carbon credits does not “comply with agrochemical regulations”. It added that eucalyptus monocultures cover more than 300,000 hectares in Paraguay. Residents have pointed out the risks of wildfire due to “persistent drought” conditions in the country over the past five years. Apple had not responded to the allegations at the time of the investigation’s publication.
Extreme heat could triple lost work hours by century’s end
This week, Carbon Brief covers a new UN-backed report that examines the impacts of climate change on labour productivity and health.
Manual labourers, such as farmworkers and fisherfolk, are “already” being impacted by rising temperatures, according to two UN agencies.
A new report from the World Meteorological Organization (WMO) and the World Health Organization (WHO) examined the effects of climate change on heat stress in the workplace and offered technical guidance for employers, workers and policymakers.
The report called occupational heat stress a “global societal challenge”.
It also noted that both the direct and indirect impacts of environmental heat stress will worsen and spread geographically as the world continues to warm.
In a press conference prior to the release of the report, Dr Rüdiger Krech, interim director of the WHO’s environment, climate change and migration programme, said the report offered the “most comprehensive evidence yet on how rising temperatures are harming workers”.
‘Adverse consequences’
In 1969, the WHO published a technical report on the potential health threats of working under environmental heat stress. The report concluded that “knowledge relating to occupational heat exposures is inadequate in many respects”. It recommended several priorities for further research.
The new report updated the 1969 report with decades’ worth of research showing that workplace heat stress “directly threatens workers’ ability to live healthy and productive lives and leads subsequently to worsening poverty and socioeconomic inequality”.
It found that around half of the global population currently experiences “adverse consequences of high environmental temperatures”. Agricultural work is “often regarded as [one of] the highest-risk occupations” for work-related heat illness, it said.
Farmworkers typically work with little or no shade during the hottest hours of the day. Some groups of agricultural workers – such as those who manually spray pesticides or other agrochemicals – face added risk of heat stress due to the protective gear that they must wear.
The report warned that, while several early warning systems are in place to protect people during heatwaves, these systems may not be adequate to protect workers, who differ in their exposure to heat and their ability to adapt.
Raising the risk
The new report also examined the changing risks of occupational heat exposure in the context of climate change.
Citing the work of the Intergovernmental Panel on Climate Change, it noted that each additional 0.5C of warming “significantly raises the risk of longer and more severe heatwaves”. The largest relative shifts will take place in the temperate mid-latitudes, but the frequency of dangerous events will also increase in the tropics, which have the “greatest workplace heat stress problems at present”.
Under the emissions scenario that aligns with current national climate policies, the worst-affected countries will face annual work hour losses of up to 11% by the end of the century – up from 2-4% today, the report said.
Previous research has found that 3C of warming could reduce global labour capacity by up to 50%, driving up food prices and requiring higher levels of agricultural employment to make up the shortfall.
Krech told the press conference:
“Protecting workers from extreme heat is not only a health priority, it is essential to building resilient, equal and sustainable societies in a warming world.”
ACCESS ISSUES: Civil Eats covered a group in northern California that works to bridge the gap between emergency-relief organisations and local food-systems workers during emergencies.
DELVING INTO THE DEPTHS: NPR Shortwave addressed the importance of mapping the entire seafloor for “improving human life”, from tsunami alerts through to renewable energy.
CONSEQUENCES IN CALIFORNIA: A California state legislator and the president of the California Farm Bureau wrote in the New York Times how immigration raids on farmworkers increase food waste and drive up prices.
‘MESSY GARDENS’: A CBC News video explored how having a “messy garden” can bring benefits for biodiversity and contribute to mitigating climate change.
- A study published in One Earth found that the “planetary boundary” of ecosystem integrity may have already been breached on up to 60% of the Earth’s land surface. Researchers modelled ecological disruption and found that 38% of the Earth is “already at high risk of degradation”.
- Research in the Proceedings of the National Academy of Sciences found that if global temperatures rise 2.3C above pre-industrial temperatures, soil bacterial and fungal diversity would be reduced by 16 and 19%, respectively. It also found that soil organic carbon would drop by 18% under that level of warming.
- Eating a diet of biodiverse, plant-based foods can have “modest benefits” for both sufficient nutrition and environmental health, according to new research published in Nature Food. The study found that diversity of animal-sourced foods was inversely associated with both greenhouse gas emissions and land use.
