Key developments
Migratory species in peril
EXTINCTION THREAT: A new UN-backed report, the “State of the World’s Migratory Species” found that one in five of the species listed under the Convention on the Conservation of Migratory Species of Wild Animals (CMS) is “threatened with extinction”, with nearly half experiencing population declines. The report examined the status of nearly 1,200 species protected under the CMS, concluding: “The impacts of climate change are already being felt by many migratory species, and these impacts are expected to increase considerably over the coming decades, not just as a direct threat to species but also as an amplifier of other threats.” Conserving these species “is extremely difficult because they cross nations, continents, even hemispheres”, Dr Amanda Rodwald, the director of the Center for Avian Population Studies at the Cornell Lab of Ornithology, told Grist.
A RAY OF HOPE: Several news outlets covered the report. Yale Environment 360 noted that the report “is the first comprehensive assessment” of migratory species. It added that “marine life is particularly at risk” due to overfishing, with 97% of marine migratory species “facing extinction”, including sharks, rays and sturgeons. According to Inside Climate News, “the numbers could be even more dire because the CMS treaty…covers only about a quarter of the world’s known migratory species”. But, it added, “the authors emphasise that further species declines and habitat destruction are not inevitable”, highlighting success stories, such as that of the humpback whale. Yale E360 quoted Inger Andersen, head of the UN Environment Programme, who said: “The global community has an opportunity to translate this latest science of the pressures facing migratory species into concrete conservation action.”
CARNIVORE CONSERVATION: The report was released on 12 February at the 14th Conference of the Parties to the CMS, being held this week in Samarkand, Uzbekistan. The next day, the CMS signed a memorandum of understanding with the International Union for Conservation of Nature (IUCN) that “formalise[d] a commitment for IUCN and CMS to work together to protect threatened African carnivores”, according to the IUCN. The organisation said that its partnership would “raise funds and facilitate frontline conservation action targeted at protecting and recovering” lions, cheetahs, leopards and African wild dogs. Dr Grethel Aguilar, director-general of the IUCN, highlighted that those four are “species that are vital to healthy ecosystems and on which many other species depend”.
Farmers’ protests across the EU
WAVE OF PROTESTS: Carbon Brief reported that farmers across the EU, including in Belgium, France, Germany and Greece, have taken to the streets in protest over the past weeks due to a “series of concerns, including competition from cheaper imports, rising costs of energy and fertiliser and environmental rules”. Carbon Brief analysed the main demands from farmer groups in seven EU countries and found that many – but not all – were related to climate change and biodiversity conservation. Several points of contention were related to policies that have not yet been implemented, such as the EU’s upcoming nature restoration law and a pending trade agreement with several South American countries. The EU is working on other climate and biodiversity regulations ahead of parliamentary elections in June this year.
COORDINATED CONCERNS: Truckers, beekeepers and foresters joined the farmers in protest in Poland, Euractiv reported. According to a Polish apple grower, these groups are opposed to impositions that would result from the European Green Deal as well as “the influx of low-quality Ukrainian food to Poland under the liberalised EU trade rules”. In an interview with the outlet, Jacek Zarzecki of the Federation of Agricultural Producers Union said that regulations aimed at reducing agricultural emissions and enhancing animal welfare were not sufficiently supporting farmers. Meanwhile, there have also been protests in India, with Al Jazeera reporting that Indian security forces fired tear gas and authorities suspended internet services in a bid to stop thousands of farmers marching on New Delhi. Their demands “include higher support, guaranteed prices for their produce, and forgiveness for loans, as well as a clutch of other concessions”, the outlet said.
REGULATION ROLLBACK: Earlier this month, protests were “brought to the doorstep of the European parliament” in Brussels as farmers pushed the body “to abandon its most demanding emissions targets”, the Times wrote. It reported that “Brussels has struggled to contain the fightback” against agricultural regulation and that, in response, the European Commission has decided to “scrap” a plan to reduce emissions of methane, nitrogen and other gases from agriculture by 30%. Bloomberg added that the EU has also abandoned its plan to reduce the use of pesticides by half by 2030 under farmers’ pressure. It quoted European Commission president Ursula von der Leyen, who said the regulation had become a “symbol of polarisation”. She added that a new proposal drafted with the input of more stakeholders “may be put forward”, Bloomberg wrote.
GENE-EDITED AFFAIRS: Meanwhile, Politico reported that the European parliament passed “a tight plenary vote” that would put gene-edited seeds – marketed as a way to reduce climate impacts on agriculture – on the market. The outlet said the patentable so-called “supercrops” could pave the way for half a dozen big suppliers to strengthen their market domination. Member states are currently “deadlocked” in negotiating the proposal, Politico added. Science explained that part of the controversy arises from whether gene-edited seeds will be protected intellectual property as “conventionally bred plants in Europe cannot be patented”.
Spotlight
New nature fund takes its first steps
On 9 February, the governing body of a “game-changing” new fund for biodiversity met for the first time in Washington DC. Carbon Brief unpacks the highlights and major decisions made at that meeting. (For more, see Carbon Brief’s detailed Q&A on progress since COP15.)
Conceived at the 2022 UN COP15 biodiversity summit in a last-minute compromise amid calls by many developing countries for a distinct fund, a landmark new nature fund is now on the verge of becoming real.
Meant to finance a tall order of conservation targets for this decade, the Global Biodiversity Framework (GBF) Fund is housed under the Global Environment Facility (GEF), a multilateral fund with 186 member governments. The GEF is entrusted with supporting a wide range of global environmental action. At the GEF council’s 66th meeting this week, countries agreed to invest a cumulative $1.1bn in biodiversity, climate change, restoration and pollution control.
Dr Dawda Badgie, the elected chairperson of the GBF Fund council, who hails from the Gambia, said:
“These decisions can change peoples’ lives for years to come…We have to act collectively about the challenges we are facing. They do not spare anybody.”
Members from different countries met for the first time as the GBF Fund council to approve policies framing how multilateral finance for nature in this decade will flow. The GBF Fund’s initial work programme to lay out its funding agenda is expected in June this year and financing is to follow before the end of 2024.
Funding flows
Of the decisions approved in Washington DC, the most crucial was one on how the fund’s resources will be allocated. It empowers the GEF chief executive to approve projects up to $5m and calls for a mid-term review of all projects over $2m.
The council committed to prioritising 20% of its funds to support Indigenous and local community-led conservation projects, and at least 36% to small island states and least-developed countries.
According to the Earth Negotiations Bulletin (ENB), calls for a written policy on the participation of Indigenous peoples in deciding what these projects should look like were also taken on board by the GEF, which agreed to develop a draft methodology by June. “Projects should engage with Indigenous peoples and local communities as partners and co-designers rather than just beneficiaries,” said the International Indigenous Forum on Biodiversity (IIFB).
Youth groups advocated for a similar, but additional, direct funding line for women and youth, ENB added. Council members pointed to sparse funding available to many countries and suggested that organising projects in regional clusters, such as the Amazon, would ensure funding would be meaningful and impactful.
The council also decided how projects under the fund will be designed and approved, with funding priorities guided by the Convention on Biological Diversity’s (CBD) Conference of the Parties, or COP.
The council also approved the fund’s budget and administrative costs, including World Bank levies – even though they are still being negotiated – and staffing decisions. The IIFB urged the council to recruit staff who have experience working with Indigenous communities.
Seed capital shortage
At the meeting, Spain’s secretary of state for the environment, Hugo Morán Fernández, announced a contribution of €10m to the GBF Fund, joining Canada, Germany, the UK and Japan in pledging seed capital to kickstart the fund.
However, the World Bank’s representative at the meeting said that of these countries’ total $219.2m in pledges, only $54.6m has actually been paid into the fund so far (by Germany and Spain). This, observers warned, brings the fund’s actual capital into question and sits in sharp contrast to the yawning $700bn biodiversity finance gap.
Dr David Cooper, acting CBD chief, said in a statement:
“If we’re honest, we need an order of magnitude more in the coming few years, if we are going to meet that COP request of…scaling up finance commensurate with the targets of the GBF.
“We need this frontloading. We need this support for actions on the ground right away if we are going to have any chance of achieving those ambitious targets by 2030.”
News and views
INDONESIAN ELECTION: “More than 100 million people” were expected to cast their votes in the Indonesian election today, according to the New York Times. It continued: “As one of the world’s biggest exporters of coal, nickel and palm oil, Indonesia has a large role to play in the climate change crisis.” The vote “is widely seen as a referendum on the legacy” of two-term president Joko Widodo, the newspaper added. Early results, or “quick counts”, after the polls closed showed a “commanding lead” for current defence minister Prabowo Subianto, who has “presented himself as an heir to [the] immensely popular sitting president”, the Associated Press reported.
STRIKE FOR SAFETY: A partial strike within Brazil’s environmental agencies is “threatening” the country’s climate goals, according to a news article in Nature. Since early January, staffers at several agencies have stopped their field visits, “where they conduct deforestation surveillance and help to shut down illegal mining operations”. Nature added that “if their demands aren’t met, they could soon turn up the heat on the government and stop working altogether”. The workers contend that they are overworked and underpaid and that their safety is at risk when they are out in the field. The country is already feeling the impacts of the strike, Nature reported: “Inspectors issued 93% fewer environmental fines in the Amazon during the first two weeks of January than in the same period last year.”
AVOCADO CONFLICT: The organisation Climate Rights International said in a press release that “the Biden administration should act on a call by US senators to work with the Mexican government to prevent avocados grown on illegally deforested lands from reaching US markets”. A 2023 Climate Rights International investigation pointed out that avocado exports to major markets such as the US and EU contribute to illegal deforestation, water theft, and “dire consequences for the rights of local residents” in Mexico. Indigenous leaders and residents in two central Mexican states defending their territories from avocados’ expansion have been victims of violence, attacks and murders over the past decade, the report added.
AGRARIAN COURTS: In December, Colombian president Gustavo Petro announced a new court system that would help resolve land ownership conflicts between peasant farmers, or campesinos, and large companies, Mongabay reported. The system will eventually encompass 70 agrarian courts, with the first five set to begin operating by 2 May. According to Mongabay, “peasant farmers have long struggled for recognition by the state”. It added that while some advocates of farmers’ rights welcomed the announcement, others have voiced concerns about the lack of specialisation of judges and the risk of not having Indigenous participation in implementing the court system.
MULTITUDE OF MANGROVES: Pakistan expanded its mangroves nearly threefold over the past 30 years, according to an analysis of satellite data, Mongabay reported. Mangroves covered 48,331 hectares in 1986 and grew to 143,930 hectares in 2020. The analysis attributed the expansion to government and NGO efforts to boost the conservation of mangroves through restoration, research and awareness-raising campaigns, Mongabay explained. The study also acknowledged the role of fisher communities in planting and protecting such ecosystems, as well as “massive tree-planting projects” carried out bynational and provincial governments since 2008.

New science
Arctic marine heatwaves forced by greenhouse gases and triggered by abrupt sea-ice melt
Communications Earth and Environment
A new attribution study revealed that marine heatwaves in the Arctic are being triggered by a combination of greenhouse-gas-induced warming and “abrupt” melting of sea ice. The research found that the most intense Arctic marine heatwave on record, which occurred in 2020, had temperatures up to 4C higher than normal and lasted for 103 days, “would be exceptionally unlikely in the absence of greenhouse gas forcing in terms of both intensity and duration”. According to the paper, marine heatwaves in the Arctic can impact fish stocks and marine food chains, thus affecting Indigenous communities and fisheries. The study concluded that if greenhouse gas emissions continue to rise, “moderate marine heatwaves in the Arctic will very likely persistently reoccur”.
Widespread temporal and spatial variability in net ecosystem productivity under climate change
One Earth
A new study found that future net ecosystem productivity – the difference between the amount of carbon taken out of the air through photosynthesis and the amount respired by plants – is more variable than previously thought. Using a combination of data and models, researchers explored how ecosystem productivity might vary in space and time under different emissions scenarios. They found that under a “very low” emissions scenario, carbon storage in the Amazon is “projected to decline considerably” by 2100. Under higher emissions scenarios, carbon storage “will likely increase” due to the CO2 fertilisation effect, the study said – although it did not take into account disturbances such as drought and fire. The result, the researchers wrote, “highlight[s] the need for effective actions to maintain [the Amazon’s] carbon storage capacity under climate change”.
Projected changes in mean and extreme precipitation over northern Mexico
Journal of Climate
The frequency of extreme rainfall events in northern Mexico would likely double by the end of the century under a scenario of very high emissions, “exacerbating the flood risk for vulnerable communities”, according to new research. The study found that by the end of the century, average and extreme rainfall would decrease west of the Sierra Madre highlands and increase to the east, with “implications for the agricultural sector, economy and infrastructure”. The region is home to 32 million people, yet, the study says, few studies have analysed future trends in mean or extreme rainfall there.

On the Farm, the Hidden Climate Cost of America’s Broken Health Care System
American farmers are drowning in health insurance costs, while their German counterparts never worry about medical bills. The difference may help determine which country’s small farms are better prepared for a changing climate.
Samantha Kemnah looked out the foggy window of her home in New Berlin, New York, at the 150-acre dairy farm she and her husband, Chris, bought last year. This winter, an unprecedented cold front brought snowstorms and ice to the region.

A Little-Used Maneuver Could Mean More Drilling and Mining in Southern Utah’s Redrock Country
Two Utah Congress members have introduced a resolution that could end protections for Grand Staircase-Escalante National Monument. Conservation groups worry similar maneuvers on other federal lands will follow.
Lawmakers from Utah have commandeered an obscure law to unravel protections for the Grand Staircase-Escalante National Monument, potentially delivering on a Trump administration goal of undoing protections for public conservation lands across the country.

Heatwaves driving recent ‘surge’ in compound drought and heat extremes
Drought and heatwaves occurring together – known as “compound” events – have “surged” across the world since the early 2000s, a new study shows.
Compound drought and heat events (CDHEs) can have devastating effects, creating the ideal conditions for intense wildfires, such as Australia’s “Black Summer” of 2019-20 where bushfires burned 24m hectares and killed 33 people.
The research, published in Science Advances, finds that the increase in CDHEs is predominantly being driven by events that start with a heatwave.
The global area affected by such “heatwave-led” compound events has more than doubled between 1980-2001 and 2002-23, the study says.
The rapid increase in these events over the last 23 years cannot be explained solely by global warming, the authors note.
Since the late 1990s, feedbacks between the land and the atmosphere have become stronger, making heatwaves more likely to trigger drought conditions, they explain.
One of the study authors tells Carbon Brief that societies must pay greater attention to compound events, which can “cause severe impacts on ecosystems, agriculture and society”.
Compound events
CDHEs are extreme weather events where drought and heatwave conditions occur simultaneously – or shortly after each other – in the same region.
These events are often triggered by large-scale weather patterns, such as “blocking” highs, which can produce “prolonged” hot and dry conditions, according to the study.
Prof Sang-Wook Yeh is one of the study authors and a professor at the Ewha Womans University in South Korea. He tells Carbon Brief:
“When heatwaves and droughts occur together, the two hazards reinforce each other through land-atmosphere interactions. This amplifies surface heating and soil moisture deficits, making compound events more intense and damaging than single hazards.”
CDHEs can begin with either a heatwave or a drought.
The sequence of these extremes is important, the study says, as they have different drivers and impacts.
For example, in a CDHE where the heatwave was the precursor, increased direct sunshine causes more moisture loss from soils and plants, leading to a drought.
Conversely, in an event where the drought was the precursor, the lack of soil moisture means that less of the sun’s energy goes into evaporation and more goes into warming the Earth’s surface. This produces favourable conditions for heatwaves.
The study shows that the majority of CDHEs globally start out as a drought.
In recent years, there has been increasing focus on these events due to the devastating impact they have on agriculture, ecosystems and public health.
In Russia in the summer of 2010, a compound drought-heatwave event – and the associated wildfires – caused the death of nearly 55,000 people, the study notes.

The record-breaking Pacific north-west “heat dome” in 2021 triggered extreme drought conditions that caused “significant declines” in wheat yields, as well as in barley, canola and fruit production in British Columbia and Alberta, Canada, says the study.
Increasing events
To assess how CDHEs are changing, the researchers use daily reanalysis data to identify droughts and heatwaves events. (Reanalysis data combines past observations with climate models to create a historical climate record.) Then, using an algorithm, they analyse how these events overlap in both time and space.
The study covers the period from 1980 to 2023 and the world’s land surface, excluding polar regions where CDHEs are rare.
The research finds that the area of land affected by CDHEs has “increased substantially” since the early 2000s.
Heatwave-led events have been the main contributor to this increase, the study says, with their spatial extent rising 110% between 1980-2001 and 2002-23, compared to a 59% increase for drought-led events.
The map below shows the global distribution of CDHEs over 1980-2023. The charts show the percentage of the land surface affected by a heatwave-led CDHE (red) or a drought-led CDHE (yellow) in a given year (left) and relative increase in each CDHE type (right).
The study finds that CDHEs have occurred most frequently in northern South America, the southern US, eastern Europe, central Africa and south Asia.

Threshold passed
The authors explain that the increase in heatwave-led CDHEs is related to rising global temperatures, but that this does not tell the whole story.
In the earlier 22-year period of 1980-2001, the study finds that the spatial extent of heatwave-led CDHEs rises by 1.6% per 1C of global temperature rise. For the more-recent period of 2022-23, this increases “nearly eightfold” to 13.1%.
The change suggests that the rapid increase in the heatwave-led CDHEs occurred after the global average temperature “surpasse[d] a certain temperature threshold”, the paper says.
This threshold is an absolute global average temperature of 14.3C, the authors estimate (based on an 11-year average), which the world passed around the year 2000.
Investigating the recent surge in heatwave-leading CDHEs further, the researchers find a “regime shift” in land-atmosphere dynamics “toward a persistently intensified state after the late 1990s”.
In other words, the way that drier soils drive higher surface temperatures, and vice versa, is becoming stronger, resulting in more heatwave-led compound events.
Daily data
The research has some advantages over other previous studies, Yeh says. For instance, the new work uses daily estimations of CDHEs, compared to monthly data used in past research. This is “important for capturing the detailed occurrence” of these events, says Yeh.
He adds that another advantage of their study is that it distinguishes the sequence of droughts and heatwaves, which allows them to “better understand the differences” in the characteristics of CDHEs.
Dr Meryem Tanarhte is a climate scientist at the University Hassan II in Morocco, and Dr Ruth Cerezo Mota is a climatologist and a researcher at the National Autonomous University of Mexico. Both scientists, who were not involved in the study, agree that the daily estimations give a clearer picture of how CDHEs are changing.
Cerezo-Mota adds that another major contribution of the study is its global focus. She tells Carbon Brief that in some regions, such as Mexico and Africa, there is a lack of studies on CDHEs:
“Not because the events do not occur, but perhaps because [these regions] do not have all the data or the expertise to do so.”
However, she notes that the reanalysis data used by the study does have limitations with how it represents rainfall in some parts of the world.
Compound impacts
The study notes that if CDHEs continue to intensify – particularly events where heatwaves are the precursors – they could drive declining crop productivity, increased wildfire frequency and severe public health crises.
These impacts could be “much more rapid and severe as global warming continues”, Yeh tells Carbon Brief.
Tanarhte notes that these events can be forecasted up to 10 days ahead in many regions. Furthermore, she says, the strongest impacts can be prevented “through preparedness and adaptation”, including through “water management for agriculture, heatwave mitigation measures and wildfire mitigation”.
The study recommends reassessing current risk management strategies for these compound events. It also suggests incorporating the sequences of drought and heatwaves into compound event analysis frameworks “to enhance climate risk management”.
Cerezo-Mota says that it is clear that the world needs to be prepared for the increased occurrence of these events. She tells Carbon Brief:
“These [risk assessments and strategies] need to be carried out at the local level to understand the complexities of each region.”
