RECORD-LOW LOSS: Amazon deforestation rates have fallen to their lowest level since 2019, according to a report covered by Agence France-Presse. The newswire called the figures “good news” for president Luiz Inácio Lula da Silva, but said the rate of deforestation is still “breathtaking”, with five trees felled every second, on average. Separately, a report from Rainforest Foundation Norway found that the “currently anticipated growth in Brazilian beef production may lead to deforestation of ~57,000km2 in the Amazon by 2034”.
ROAD AND RAIL: The Brazilian government will invest $75m into a new highway “cutting through the Amazon rainforest”, reported Deutsche-Welle. The Associated Press said the administration also announced an environmental protection plan to “safeguard the forest from potential impacts from the highway”, but added that environmentalists still fear the move “could speed up Amazon deforestation”. Separately, Inside Climate News reported on a Brazilian supreme court ruling that has brought a 965km railway through the Amazon “one step closer to reality”.
BANNED IMAGES: Mongabay reported that “Brazil’s Congress has passed a bill prohibiting environmental agencies from using satellite images to restrict the commercial use of illegally deforested lands”. According to the outlet, supporters say that “satellite-only enforcement infringes upon farmers’ right to a fair defense”, while critics argue that the bill will “weaken environmental protection” and “create unsafe conditions” for Brazil’s federal environmental police. Separately, the Brazilian government has committed more than $600m (£446m) to “foster ecological investment in the Amazon region”, according to the Associated Press.
El Niño forecast and extreme heat
‘SUPER’ STRESSED: The predicted “super” El Niño event would add stress to an “already dysfunctional and fragile global food system”, wrote the University of Sussex’s Prof Benjamin Selwyn in a commentary in the Conversation. He added that “El Niño alters rainfall, shifts jet streams and raises global temperatures”, all of which could damage harvests this summer. Reuters noted that the forecast for the phenomenon is “particularly worrying”, due to the predicted strength of the event and the contribution of climate change.
HEAT BURDEN: “Scorching temperatures” in India have “disrupted daily life across several northern states”, said the Washington Post. The outlet added: “Some farmers have switched to nighttime work to avoid scorching temperatures as a heatwave grips large parts of India.” The heatwave is also affecting Nepal, as high temperatures have “added burdens to public health, education, agriculture, livestock, environment, employment and public infrastructure”, reported Nepal News.
‘MIND-BOGGLING’ HEAT: Meanwhile, a “heat dome” over western Europe broke UK temperature records for the month of May. Carbon Brief summarised how the “mind-boggling” heatwave was covered in both national and international press. Agence France-Presse wrote that parts of Italy approved rules limiting work in conditions “with prolonged exposure in the sun” during the hottest part of the day. The newswire added: “Farmers reported accelerated harvests as temperatures went beyond 30C across the region.”
News and views
- SNAKEBITE DANGER: “The risk of snakebites is increasing across the world as reptiles shift their habitats to cope with rising temperatures and growing human pressures,” according to new research covered in the Guardian. It added that human-snake interactions are “forecast to become more pronounced”.
- RICE RISK: “Several parts” of China are experiencing heavy rains early this year, “raising risks for agriculture and disaster management”, wrote Bloomberg. This includes “key grain-producing provinces”, as well as areas that grow rice, vegetables and fruit, added the outlet.
- DATA DROUGHT: Chile’s Quilicura wetland, just north of Santiago, is drying up as “datacentres have drained water from drought-stricken wetlands, consuming billions of litres annually”, said the Guardian. It noted that the area is home to Latin America’s “largest concentration of datacentres”.
- ACCOUNTING TRICK: A group of scientists have called on the Irish government to reject a proposal that would allow the livestock to use a metric called GWP* to measure methane emissions, reported Inside Climate News. According to the outlet, they warned that this “accounting trick” would “downplay” the industry’s emissions. (See Carbon Brief’s explainer on GWP* for more information.)

Three key findings on the state of carbon dioxide removal
This week, Carbon Brief unpacks three key findings from the third edition of the “state of carbon dioxide removal” report.
Global carbon dioxide removal (CDR) will need to increase fourfold by 2050 if the world is to have a chance of limiting global warming to 1.5C by 2100, said a new report.
Nearly all pathways to meeting the Paris Agreement’s highest ambition of keeping global temperatures to 1.5C above pre-industrial levels in 2100 involve CDR techniques – ranging from tree-planting to sucking CO2 from air with machines.
This is in addition to steep and immediate emissions cuts.
Scientists expect carbon emissions to push warming beyond 1.5C in the decade ahead, meaning that the target can only be achieved via large-scale CDR.
Here, Carbon Brief pulled out three key findings from the third state of CDR report.
‘Novel’ CDR is small, but growing
The report said that, at present, “99.9%” of existing CDR is conventional, land-based techniques, such as tree-planting and ecosystem restoration.
The world currently removes 2.2bn tonnes of CO2 (GtCO2) per year, equivalent to around 5% of gross global CO2 emissions.
The largest contributors to removing CO2 from the atmosphere are China, the US, the EU, Brazil and Russia, largely through tree-planting (afforestation) and forest restoration (reforestation).
“Novel” CDR, such as biochar and direct air capture, currently removes just 2m tonnes of CO2 annually at present, according to the report.
These methods have been growing at a rate of 40% per year – which is “insufficient for the scale-up required to meet the Paris temperature goal”, said the report.
Current ambition will not lead to net-zero
The report examined several scenarios where global temperature rise is limited to “well below” 2C by 2100, including a current ambition scenario and a highest-possible ambition scenario.
The current ambition scenario was based on “nationally determined contributions”, or NDCs, which countries submit periodically to the UN Framework Convention on Climate Change (UNFCCC).
Under this scenario, the report projected a total of 5.9GtCO2 of CDR by 2050 and 12GtCO2 by 2100. This scenario would result in end-of-century warming of 1.7-2.7C.
Importantly, the report said, current ambition does not result in the world reaching net-zero CO2 levels, “meaning that global temperatures would continue to rise” – albeit more slowly – beyond 2100.
Under the highest-possible ambition scenario, CDR scales up to 8.8GtCO2 by mid-century and 15.3GtCO2 by the end of the century. This results in global temperatures peaking at 1.7-1.8C around 2050 and the world achieving net-zero emissions around that time.
Reducing emissions now lowers the need for future CDR
While many countries include some amount of CDR in their NDCs, there is currently a large gap between the amount of CDR pledged and the amount that will be needed to limit global temperature rise to 1.5C by the end of the century, said the report.
This quantity is referred to as the “CDR gap” – the difference between what is pledged and what is needed.
The size of the CDR gap is dependent on both the pledges made by countries and the choice of the “benchmark” scenario against which they are measured.
Current NDCs and other country submissions to the UNFCCC total 2.5GtCO2 per year of removals in 2030 and 3.6GtCO2 per year in 2050. Using the highest-ambition scenario as a benchmark, this gives a CDR gap of 0.3GtCO2 in 2030 and 5.2GtCO2 in 2050, according to the report.
By comparison, a 10-year delay in implementing ambitious emissions reductions will result in the need to remove at least an additional 150GtCO2 from the atmosphere, compared to the most ambitious scenario.

Planned offshore oil and gas expansion threatens key marine ecosystems, report
Ocean and coastal creatures are being put at risk by the spills, noise, dredging and shipping associated with new offshore oil and gas infrastructure, says a new report by a group of environmental NGOs.
The report by a group of twelve environmental groups analysed planned new offshore oil and gas blocks covering 430,000 square kilometres – an area the size of Sweden – in 11 countries.
Blocks in countries such as Kenya, Indonesia and Australia overlap with some of the planet’s hotspots for marine biodiversity, home to mangroves, coral reefs, sea turtles, sharks and whales.
Oil and gas expansion is advancing in spite of the legal protections already in place, the report says, with a third of the area being licensed overlapping with marine and coastal protected areas.
“It is alarming to see the research findings and the sheer scale of fossil fuel expansion trajectories threatening the health and future of our shared ocean,” said Tyson Miller, Executive Director of Earth Insight, one of the environmental NGOs involved in the report.
At the first conference on Transitioning Away from Fossil Fuels in Santa Marta, around 60 countries floated the idea of creating “fossil-fuel-free zones”, which would seek to place limits on coal, oil and gas in areas where development would lead to severe social and environmental harm.
As part of the landmark Kunming-Montreal biodiversity deal, governments have also pledged to protect 30% of the planet’s land and marine ecosystems by 2030. This could be used as an opportunity to limit oil and gas expansion in sensitive areas, Miller said.
The report says the findings “reinforce the need for governments, financial institutions and companies to stop funding and supporting offshore oil and gas expansion”, and calls for the creation of fossil-fuel-free zones in “high-value marine and coastal areas”.
Oil bidding in biodiversity hotspots
As one of the case studies, Kenya — which is set to host the Our Ocean Conference in Mombasa later this month — has opened 50 offshore oil and gas blocks for bidding in the Lamu Basin, one of East Africa’s marine biodiversity hotspots.
These blocks overlap with all the region’s mangroves and coral reefs, the report says, which provide nursery habitats for fish, sea turtles and the vulnerable dugong.
These ecosystems are already under severe stress from climate change-related ocean heating and increased water acidity and could now face seismic surveys, offshore drilling, dredging, increased shipping traffic, oil spills, chemical discharge and underwater noise pollution.
The government estimates that oil production will start by 2026, aligning with “global best practices”, and has said the Lamu basin has vast “untapped potential”. The country is expected to open bidding for the first 10 blocks by September.

Muturi wa Kamau, network coordinator for the Kenya Oil and Gas Working Group, said in a statement that the country “is preparing to open ecologically sensitive areas for fossil fuel exploration” while positioning itself as a leader in ocean diplomacy.
“The question is: at what cost are we willing to risk these fragile ecosystems and the livelihoods of coastal communities who have depended on them for generations?” Kamau said.
Australia’s Otway Basin
After a four-year pause, Australia — which will act as co-presidency of the COP31 climate summit — resumed offshore exploration in the Otway basin last year, with American energy firm ConocoPhillips among the operators approved for exploratory drilling off the country’s southern coast.
The sites under exploration are as close as one kilometre from a series of marine reserves known as sanctuaries for pygmy blue whales, who travel thousands of kilometres to reproduce in those waters. Orange roughy, a deep-sea fish that can live for over 140 years, may also be harmed.
In total, the report analysed new LNG export projects in Argentina, Alaska, Mexico and Tanzania, as well as expanded offshore oil and gas licensing in Australia, Cameroon, Indonesia, Jamaica, Kenya, Norway, and Trinidad and Tobago.

The scramble to stockpile critical minerals could drive up energy transition costs
As competition for minerals needed to produce clean energy technologies intensifies, a growing number of countries have resorted to an age-old mechanism to cope with the threat of scarcity: stockpiling.
The world’s biggest economies are racing to shore up reserves of cobalt, lithium, graphite and rare earths, which are needed to produce batteries, electric vehicles, wind turbines and electric systems to wean the global economy off fossil fuels. The same minerals are also increasingly sought after to manufacture military hardware and chips for AI, adding further pressure on supplies.
But the cutthroat scramble to build up reserves threatens to drive up the costs of the energy transition by intensifying competition and pushing up prices of key materials needed to produce clean energy technologies, research published today has found.
“If you undermine the financial viability of [clean energy] projects through higher raw material costs, you’re going to delay their roll-out,” co-author Hugh Miller, the critical minerals lead at the Centre for Economic Transition Expertise at the London School of Economics and Political Science, told Climate Home News.
Stockpiling “is happening, whether we like it or not”, said Miller. “But if we’re going to do it, we need to have it in a coordinated manner that means we don’t have massive market volatility and adverse implications from every country trying to go at it alone,” he added.
The rise of stockpiles
A growing number of governments have adopted national stockpiling programmes in response to heightened geopolitical tensions around mineral supply chains.
Earlier this year, US President Donald Trump announced the establishment of a critical mineral reserve known as “Project Vault” to protect American businesses from shortages after China imposed export restrictions on rare earth supplies.

Beijing suspended the measures until November as part of a trade truce with Washington but the episode spooked Western governments and exposed how strategic materials can be weaponised to achieve geopolitical objectives.
Australia, China, the EU and India have also announced measures to create strategic mineral reserves. Japan and South Korea already have long-standing mineral stockpiling programmes.
“Legitimate concerns”
“There are legitimate concerns with regards to potential global shortages of these minerals,” said Miller, citing rapidly rising and concurrent mineral demand for the energy transition, AI, data centres, and military technologies, combined with underinvestment in new supplies for some minerals, such as copper.
While stockpiling can serve as an emergency response mechanism during acute shortages, it does nothing to address the underlying concentration risks in mineral supply chains. The Democratic Republic of Congo holds around 70% of the world’s cobalt reserves, for example, while China dominates the processing of 19 out of 20 minerals deemed critical by a large number of nations.
Uncoordinated stockpiling programmes risk heightening the price volatility they are designed to hedge against, according to the report.
Researchers found that if Australia, China, the EU, India, Japan, South Korea and the US simultaneously built reserves of minerals to cover six months of imports, the aggregate stockpile demand could represent up to 34% of global annual cobalt supply and over 10% of global lithium, graphite and copper supply. That could cause a shock to the market, triggering the shortages and price spikes they are trying to avoid.
Miller said it was unlikely that every country would stockpile at that rate, but aggregate stockpiling demand of just 5% of global mineral supply would have an impact on prices.
Coordinating stockpiles: a role for the IEA?
Researchers found that avoiding the negative impacts of stockpiling requires global coordination over how mineral stocks are accumulated and released – a mechanism which already exists for other commodities, including oil.
Coordination should include agreed rules for countries to build up their stocks over a slow and staggered timeline and pre-agreed conditions for releasing reserves to provide market predictability and reduce the risk of price spikes.
The International Energy Agency (IEA), which was established after the 1970s oil crisis to coordinate emergency oil stock releases among member countries, is best placed to oversee such a mechanism, they say.
Earlier this year, IEA member countries called on the agency to strengthen its work on critical minerals, including by providing support to countries “that choose to establish and expand critical minerals stockpiling systems”.
But Miller and his co-author Pau Morandi, a policy fellow at the Centre for Economic Transition Expertise, argue that members should go one step further and mandate the IEA to coordinate the security of supplies, rather than only helping individual governments.
The IEA has been contacted for comment.
A call to action for the G7
Miller said he hoped the research could be picked up by the G7 group of wealthy countries, which could lead on mandating the IEA to take on this coordination role.
France, which is presiding over the group this year and is hosting leaders in Evian on the shores of Lake Geneva in mid-June, has made strengthening the resilience of critical minerals value chains a priority.
In a communique last month, finance ministers agreed to “deepen and expand our cooperation among G7 members and with like-minded partners” to strengthen and diversify critical mineral supply chains and to continue discussions “on how to best organise analytical cooperation”.
Sebastien Treyer, executive director of the Paris-based Institute for Sustainable Development and International Relations (IDDRI), said he hoped the G7 leaders’ summit can help move the discussion on critical minerals towards greater international cooperation to secure the resources the world needs to build a clean economy.
From inclusive and mutually beneficial partnerships to mine resources to stockpiling minerals, “we need to coordinate more like a trade organisation than something that is about securing supply,” he said.
