Key developments
New sector targets in renewable portfolio standard
NEW QUOTAS: China has published the 2025-2026 provincial quotas for renewable energy consumption, which for the first time included sectoral targets for iron and steel, cement, polysilicon and certain types of data centres, industry news outlet BJX News reported, as well as updates to the aluminium sector targets established last year. Bloomberg said that the steel, cement and polysilicon sectors will need to use low-carbon energy to “meet between 25% and 70% of their demand” under the policy. Energy news outlet International Energy Net noted that Sichuan, Yunnan and Qinghai provinces faced the “highest quotas”, at 70%. (For comparison, the average provincial quota is 38%, Carbon Brief calculated. A separate quota for these three provinces that does not include hydropower is much closer to the national average.)
POWER RUSH: In contrast to expectations that renewable installations in China would slow for the rest of 2025, the state-run thinktank State Grid Energy Research Institute estimated that 380 gigawatts (GW) of solar, 140GW of wind power and 120GW of thermal power (likely mostly coal) will be added this year, Bloomberg reported. It noted that the solar figure is “more than 50% higher than forecasts from the leading solar industrial group”. According to NEA data, the estimate implies China will add 182GW in solar, 94GW in wind and 102GW in thermal power between June and December.
MANAGING THE INCREASE: Li Chao, spokesperson for the National Development and Reform Commission (NDRC), told reporters that “large-scale xiaona (消纳) consumption of renewable energy is critical” given rapid capacity growth, according to industry outlet China Energy News, adding that consumption rates continue to exceed 90% – meaning no more than 10% of potential output is being wasted, according to government calculations. However, separate outlet China Energy Net reported that wind and solar utilisation rates (利用率) in some provinces fell below the government-set red line of 90%, due to rapid growth. Dr Muyi Yang, senior energy analyst for Asia at thinktank Ember, told Carbon Brief: “The recent dip in utilisation rates in the western regions is an early warning that [investment in the grid] needs to speed up.”
OPEN ARMS?: Coal power still has “room to grow” during the fifteenth five-year plan period (2026-2030) despite market challenges, China Electricity Council chief expert Chen Zongfa told BJX News. Chen said this was due to the changing “attitude of the government”, which “no longer demonises coal”. The influential State-owned Assets Supervision and Administration Commission of the State Council (SASAC) pledged to “speed up the construction of thermal power projects” and “ensure the safe and stable supply of coal”, according to China Energy News. Another China Energy News article quoted an NDRC official saying China needed to “ensure the stability of coal supply”. Meanwhile, in a visit to Shanxi, President Xi Jinping told local policymakers to transform the coal industry “from low-end to high-end” while also developing clean-energy, Xinhua said.
Floods and heatwaves
‘INTENSE’ RAINS: Several regions in China, including the southern Henan, Guizhou and Hubei provinces, were hit by “intense rainfall” throughout late June and early July, causing “severe flooding” and several deaths, Bloomberg reported, in an article noting that climate change is “fuelling” extreme weather events. Meanwhile, high temperatures “enveloped China’s eastern seaboard…raising fears of droughts and economic losses”, Reuters said, adding that “extreme heat, which meteorologists link to climate change, has emerged as a major challenge for Chinese policymakers”.

NEW WARNINGS: At the launch of the China Blue Book on Climate Change 2025 – a document outlining global and China-specific impacts of climate change – National Climate Center deputy director Xiao Chan stated that the “national average temperature in June was 21.1C”, marking the hottest June since records began, according to business news outlet 21st Century Business Herald. State news agency Xinhua quoted Chen Min, vice-minister of the Ministry of Water Resources, telling reporters that 329 rivers had flooded “above warning levels” as of 4 July. Meanwhile, the government established a new heat-health warning system, which “aims to strengthen public health preparedness amid growing climate challenges”, the state-run newspaper China Daily said.
GRID PRESSURES: Linked to high temperatures along the east coast, the National Energy Administration (NEA) revealed that China’s maximum power demand reached a “record high” of 1,465GW on 4 July, finance news outlet Yicai reported, adding that air-conditioning load “accounted for about 37%” of the peak power grid load in eastern China. Bloomberg said that the grid is “in better shape to take on peak summer demand this year”, following preparations to avoid previous blackouts.
Setting the tone on ‘overcapacity’
MIIT HAUL-UP: In a meeting with solar industry representatives, Ministry of Industry and Information Technology (MIIT) head Li Lecheng said MIIT “will further increase macro-guidance and governance of the industry” in the face of “low-price disorderly competition”, BJX News reported. The Hong Kong-based South China Morning Post (SCMP) noted that Li also said companies should be “guided” to phase out “outdated production capacity”. In its coverage, Bloomberg noted that it was “unclear” what impact the meeting would have, but that it “highlight[ed] the seriousness with which Beijing views” the issue.
CLEAR SIGNALS: The meeting followed days of signalling from China on the need to crack down on industrial overcapacity, which has been blamed for “flood[ing trading] partners’ markets with artificially low-cost goods”, according to the Financial Times. In late June, the front page of the party-affiliated newspaper People’s Daily carried an article under the byline Jin Sheping – used to signal the thoughts of party leadership on economic matters – stating that “rat race competition”, a term linked to overcapacity, would “destroy” industries such as solar, lithium-ion batteries and new-energy vehicles (NEVs). At an economic policy meeting, Xi said China must “govern low-price and disorderly competition…and promote the orderly withdrawal of outdated production capacity”, BJX News said. (He also noted the need to develop more “offshore wind power” and a “unified national market”.) On the same day, ideological journal Qiushi also published an article criticising “rat race competition”. Meanwhile, the Associated Press reported, China also “shows signs of tackling” similar overcapacity issues in the NEV industry.
EUROPE UNHAPPY: European policymakers appear unconvinced, however, with top EU diplomat Kaja Kallas telling her Chinese counterpart Wang Yi that China must “put an end to its distortive practices…which pose significant risks to European companies and endanger the reliability of global supply chains”, according to Reuters. It added that the remarks came during meetings aiming to “lay the groundwork for a summit between EU and Chinese leaders” set to take place on 24 July. Meanwhile, the EU is refusing to consider publishing a joint EU-China climate declaration at the leaders’ summit “unless China pledged greater efforts to cut its greenhouse gas emissions”, the Financial Times reported.
BRICS message on climate finance
MITIGATION FUND: The heads of the BRICS nations, a grouping of China and several other global south countries, “demand[ed] that wealthy nations fund mitigation of greenhouse gas emissions in poorer nations” at a leaders summit in early July, Reuters said. It added that, while Brazil “urged a global transition away from fossil fuels”, the resulting joint statement “argued that petroleum will continue to play an important role in the global energy mix, particularly in developing economies”. Reacting to the summit, the campaign group WWF said in a press release: “When it comes to climate, the message falls short.”
GLOBAL SOUTH VOICE: The Guardian noted that “Brazilian diplomats see the BRICS alliance as part of an emerging new world order”, noting that the summit featured “pushback against the EU” over “discriminatory protectionist measures under the pretext of environmental concerns”. Brazil also used the summit to ask “China and BRICS member states in the Middle East to be among the seed funders” for long-term financing for conservation, the newspaper said, adding that this did not seem to have been successful. The absence of Xi from the meeting, in a first at a BRICS leaders summit, sparked significant speculation around how valuable China saw the block as being.

Key takeaways from China’s latest climate adaptation progress report
China’s Ministry of Ecology and the Environment (MEE) recently published a report outlining China’s progress last year in adapting to climate change. In this issue, Carbon Brief outlines three key messages from the assessment.
Extreme weather events are becoming more severe
China’s climate was “relatively poor” (偏差) in 2024, the MEE report stated, with several “record-breaking or severely disastrous” extreme weather events.
These include extreme heat and cold, rainfall, typhoons, flooding and severe convective weather.
Weather events have generally worsened year-on-year, the report said. In 2024, China’s average temperature stood at 10.9C – the warmest since modern records began.
Similarly, national average rainfall totalled almost 698 millimetres, up 9% year-on-year. More typhoons made landfall in China in 2024 compared to 2023, of which several had “large disaster impacts”, according to the report.
It added that these events had “serious adverse” socio-economic impacts, noting that extreme weather led to at least 500 deaths or disappearances in 2024. (Statistics for deaths and disappearances were not included in the 2023 edition of the report.)
In 2024, the central government spent more than 2.5bn yuan ($350m) on “natural disaster relief funds”, covering flooding, drought and extreme cold.
Climate-resilient infrastructure still a main focus
Extreme weather is also increasingly damaging infrastructure, the report noted. For example, more than 29m users lost power due to extreme weather.
Much of the report is dedicated to describing China’s efforts to develop infrastructure that can resist or help mitigate the effects of extreme weather events.
Managing “water resources” and water conservation continued to receive a strong focus in the report, which added that, in 2024, “major water conservancy projects continued to be developed to a high quality”.
It also noted that this infrastructure buildout “played a key role” in mitigating the impact of floods in 2024, with thousands of reservoirs nationwide being used to store floodwater.
This, it said, “reduced” the impact of 26 floods on 2,300 cities and towns and 17m mu [slightly more than 1m hectares] of arable land”.
The country is also strengthening its ability to predict future extreme weather events, building more than 10,000 new monitoring and early-warning stations in 2024.
Cities are being encouraged to become more “climate resilient”, with 39 authorised to develop pilot programmes exploring possible solutions.
The report noted that, in 2024, 60 cities were developing “sponge city” projects, using nature-based solutions to absorb, collect or reuse floodwater.
Liu Junyan, project lead for the climate risk project at campaign group Greenpeace East Asia, told Carbon Brief that sponge-city solutions did seem to play a beneficial role during the deadly Henan floods in 2021, where floodwaters receded more quickly in Zhengzhou city than other areas.
“But sponge-city methods are not made to handle the extreme rainfall caused by climate change,” she added.
China’s response is relatively ‘holistic’, but disconnects remain
The MEE report emphasised that China’s overarching climate adaptation strategy covers a broad range of socio-economic impacts.
For example, it mentioned efforts in 2024 to prepare technical guidelines for assessing climate change impacts and risks. Carbon Brief understands that the aim of these efforts is to help provincial governments use more standardised, science-based assessments of climate risk, as well as how they should respond.
The report also noted efforts to develop climate-conscious behaviours, such as campaigns encouraging farmers to use “water-saving” irrigation technologies and guidelines to “enhance public awareness” of potential climate-related health risks.
Liu said China’s approach to adaptation is “holistic”, but added that it remains “top-down”, sometimes causing local needs to go unmet.
Furthermore, the report said China needs to further develop strategies for climate impacts on “urban and rural habitats” and “sensitive” industries such as finance, tourism and energy.
Watch, read, listen
HAWKS AND DOVES: The European Parliament broadcasted a debate on EU-China relations ahead of the upcoming leaders’ summit, in which European Commission president Ursula von der Leyen spoke on electric vehicles, rare earths and overcapacity.
DEFINING MOMENT: Shanghai-based news outlet the Paper interviewed former UN secretary-general Ban Ki-moon on China’s role in accelerating climate ambition this year.
CLIMATE PATH: Analysts at the Asia Society Policy Institute’s China climate hub spoke on Environment China about China’s latest emissions, clean-energy and climate diplomacy trends.
STUNTING GROWTH: The US-based National Public Radio explored how climate change is affecting China’s tea-growers, with crops “stunted” and farmers struggling with “changing rhythms”.
6%
The electrification rate of China’s transport sector – well below the economy-wide figure of close to 30% – despite the rapid adoption of NEVs, Chen Ji, executive director at China International Capital Corporation, said at the China launch of the International Energy Agency’s World Energy Investment 2025 report, attended by Carbon Brief. Chen added that the low figure was due to the lack of progress in electrifying aviation and heavy-duty trucks.
New science
Increased socioeconomic impacts with future intensifying flash droughts in China
Geophysical Research Letters
A new paper found that “China will experience longer and more severe droughts, exposing 33% of the population and 35% of gross domestic product to risks under a medium-emission scenario”. The authors analysed economic and soil moisture data over 2000-22 to quantify past changes in “flash droughts”, using models to assess future changes under different climate scenarios. The paper found that “droughts are becoming more frequent in some areas, with a twofold increase in frequency in approximately 32% of these areas by the century’s end”. It added that wealthier regions will face greater economic losses due to flash droughts.
Communications Earth & Environment
Rice cultivation in China’s Sanjiang Plain has expanded northeast by more than two million hectares between 2000 and 2020, driving up irrigation demand by 6bn tonnes, according to a new study. The authors analysed data on “rice migration”, finding that rice expansion drove up irrigation by 122% over 2000-20, while an increase in rainfall due to climate change reduced irrigation demand by 22%. The authors said their findings “highlight the urgent need to make integrated strategies balancing crop migration [with] climate change and water resource conservation”.
Climate Change Research
The poorest counties in China are much more likely to experience record-breaking extreme weather events, which may push them “back to poverty”, according to new research published in a Chinese academic journal. The study combines more than twenty models with eight extreme weather indices to assess “patterns of extreme weather across 832 poverty-alleviated counties [as well as] other counties in China”. The authors recommend actions covering “water infrastructure; disaster mitigation; catastrophe insurance; and public awareness and education” to support climate adaptation in these areas.

China Briefing 10 July 2025: New sector targets; Overcapacity dressing-down; Adaptation scorecard
The global roadmap on transitioning away from fossil fuels now being developed should be a “continuing conversation” which is part of UN climate talks, not just a one-off report, several governments told the Brazilian COP30 Presidency on Friday in Bonn.
During a 90-minute exchange of views at the annual mid-year climate talks in Germany, several European governments and the Marshall Islands said the roadmap that Brazil is due to finish by November should be incorporated into the official negotiations.
Any such push is likely to be resisted by nations whose economies are reliant on fossil fuel production. While Russia did not speak on Friday, it has said in earlier written submissions that the roadmap should not be referenced in any document approved by governments at UN climate talks.
At COP30 last year, Brazil tried to get governments to agree to produce a roadmap on how to transition away from fossil fuels but the proposal did not win consensus, with major nations like Saudi Arabia and Russia opposed.
Feedback in Bonn
To save the day, Brazil’s COP30 president André Aranha Corrêa do Lago promised at the closing plenary in Belem to draw up a voluntary roadmap in consultation with interested governments. Over 20 countries have officially submitted their opinions on this roadmap and, in Bonn on Friday, Corrêa do Lago sought their views – and those of civil society – in person after the presidency presented its findings so far.
The roadmap will also incorporate outcomes from the first global conference on transitioning away from fossil fuels held in Santa Marta, Colombia, in April and attended by around 60 countries.
A negotiator for the Marshall Islands told Friday’s meeting that at COP31 this year all governments should “welcome the collaborative effort behind the roadmap and the Santa Marta conference and for this work to be taken on to COP32 and beyond”.

COP31 leaders unveil global targets, with spotlight on electrification
Co-hosts Türkiye and Australia want countries to sign on to global targets in three of their priority areas for this year’s COP climate negotiations
A spokesperson for Switzerland said on behalf of a group of nations which includes South Korea and Mexico that the roadmap must be a “sustained process, not a one-off report” and “we would welcome an ongoing platform for dialogue, for learning and cooperation including among fossil-fuel production countries”.
“We expect more than a document, rather a process whereby we come together to develop concrete steps, recommendations and tools to prepare for the transitions,” she said, calling on the COP31 co-presidents Australia and Turkiye and COP32 host Ethiopia to “take up the leadership” for implementing the roadmap”.
Global stocktake response
France’s negotiator said the roadmap “is a process and we will need continuing discussions” as “implementation needs time”, while the UK called for a “continuing conversation, including as we head towards the second [global stocktake]”.
The global stocktake (GST) is an official five-yearly report into how the world’s governments are doing on their Paris Agreement goal to limit global warming to 1.5C above pre-industrial temperatures.
The second stocktake will be published in 2028 and governments are likely to negotiate a response to it, which could include new commitments to reduce emissions, at COP33 that year. The response to the first global stocktake included the landmark COP28 commitment to transitioning away from fossil fuels in energy systems.
“Even though it’s not a formal part of the negotiation agenda, the roadmap can be a key input for the entire information-gathering phase of the second GST,” Enrique Maurtua Konstantinidis, an independent climate policy consultant, explained to Climate Home News.
“The key is for countries not to focus the discussion on defending the roadmap itself, but rather on its content, which is what truly matters,” he added.
At the Bonn event, civil society organisations also supported continuing the roadmap inside the formal climate process.
Natalie Jones, policy adviser for the International Institute for Sustainable Development, told Climate Home News the roadmap should be “an ongoing dialogue where countries can exchange their experiences, best practices and continue implementing the [transitioning away from fossil fuels] consensus”.
Russian resistance
But economies reliant on fossil fuel production are likely to oppose incorporating the roadmap into negotiations in Bonn and at COP summits. Russia’s written submission to Brazil’s consultation says the roadmap was not agreed by governments at COP30.
It says such work should therefore take place on the margins of the UNFCCC process, adding that “ the inclusion of any references to the “Roadmap” in the agenda or in official or informal documents” at Bonn or COP “would constitute a deviation from previously agreed consensus outcomes”.
Other major oil and gas producers like Saudi Arabia have not made written or spoken submissions and the US, as it has left the Paris Agreement, is not involved in discussions. But countries other than Russia are likely to resist incorporating the roadmap into official talks.
The submission by Japan, which is not a major producer of fossil fuels but consumes them from overseas, suggests nervousness about the roadmap. It asks Brazil for clarity on how the roadmap is “envisaged to be utilised” and argues that as many countries continue to rely on fossil fuels for electricity, a full and fast shift to “full decarbonisation” is “challenging.
After Friday’s event, Corrêa do Lago told Climate Home News that “the suggestions and the key milestones of the roadmap are not clear yet”. He added that the next step for the COP30 presidency will be to “sit down in July and August to really prepare” the content.
The veteran Brazilian diplomat added that the roadmap will have a section on the challenges of the transition and another section on solutions.
National fossil fuel roadmaps
Brazil, as COP30 president, is drawing up the global roadmap but its leader Lula da Silva has also ordered his officials to draw up a national roadmap.
In April, France became the first and so far only nation to produce a roadmap, which amalgamated different existing energy and decarbonisation plans and targets. Colombia is reportedly drawing up a roadmap too, based on a draft document by academics.
On Friday, a coalition of nearly 100 civil society organisations called on the COP31 co-presidents Australia and Türkiye to both come up with national roadmaps in order to “lead by example”. Türkiye produces about a third of its electricity from coal, while Australia is the world’s third-largest fossil fuel exporter, the NGOs said.
But in the Brazil-led consultation meeting, a Norwegian negotiator downplayed the importance of separate national roadmaps for transitioning away from fossil fuels.
While they can “have a supporting role”, the official said countries’ nationally determined contributions (NDCs) “must remain the primary vehicle for driving global climate transition.”
NDCs are climate plans, usually containing emissions reduction targets, which the Paris Agreement states governments must update with higher ambition every five years.

DeBriefed 12 June 2026: El Niño begins | COP31 hosts eye electrification | Atlantic current monitoring at risk
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
El Niño begins
‘DOMINO WEATHER’: The natural weather phenomenon El Niño, which can raise global heat and “bring domino weather effects across the planet”, is now underway, the US National Oceanic and Atmospheric Administration (NOAA) declared on Thursday, reported the Washington Post. The Japanese Meteorological Administration also identified the start of El Niño on Wednesday, said Bloomberg. According to the Japanese weather agency, the event is “expected to intensify in the coming months and become very strong later in the year, persisting into at least December”, reported the outlet.
‘SUPER EVENT’: BBC News reported that “many forecasts suggest this could end up as a so-called ‘super’ El Niño” and be “among the strongest ever recorded”. It added: “Coming on top of decades of human-caused warming, it could bring another record-hot year – most likely in 2027 – with disruption to weather, food supplies and economies running well into that year.”
COP31 hosts eye electrification
‘35 BY 35’: COP31 hosts Turkey and Australia have called for countries to support a target of electrifying 35% of global energy use by 2035, reported Politico. Speaking at climate talks in Bonn, Germany, Turkish minister Murat Kurum said that electrification would be a “flagship priority” at the COP31 summit, noted the publication. Kurum added that “electrifying daily life, from transport to buildings and industry” could “protect families and businesses from volatile energy markets”, said the outlet.
WASTE AND BUILDINGS: Climate Home News reported that electrification was one of three priorities unveiled by the COP31 hosts, with the other two being waste and buildings. On buildings, the COP31 hosts “quietly overhauled [their] goal”, Climate Home News said. It reported: “An initial press statement on Monday set out a target ‘to achieve at least a 25% increase in energy efficiency in buildings by 2035’. But…on Tuesday, that was replaced with a different goal to ‘reduce energy consumption intensity in the building sector by at least 25% by 2035’.”
‘HARDEST’ CHALLENGE: Elsewhere in Bonn, UN climate chief Simon Stiell said “governments must stop revisiting climate commitments and start delivering on them”, South Africa’s Mail and Guardian reported. It quoted Stiell as saying: “Tackling the global climate crisis is the hardest but most important thing humanity has ever tried to do together…We are not yet where we need to be. But we are somewhere we have never been before.”
Around the world
- ETS EXTRA: The EU has agreed “stronger” price controls on “ETS2”, its planned trading system for heating and transport emissions, according to Reuters.
- OCEAN STRESS: The rate of sea level rise has doubled in 10 years amid “severe and accelerating” pressures on oceans, said a UN report covered by Time.
- CLIMATE MIGRANTS: Donald Trump’s “immigration crackdown is largely targeting people from the countries most vulnerable to displacement from climate-driven disasters”, according to Guardian analysis.
- ULTRA-RICH: Investments by the world’s ultra-rich in 2022 are linked to nearly $1tn in climate damages, according to a Greenpeace Africa analysis covered by BusinessGreen.

Captured
Solar power has overtaken gas in Asia to become the region’s third largest electricity source behind coal and hydropower, according to Carbon Brief analysis of data from the thinktank Ember. Solar became the third largest electricity source for Asia on an annual basis in April 2026, according to the analysis. In the year to April 2026, solar generated 1,727 terawatt hours (TWh), while gas generated 1,711TWh, it added.
Spotlight
Atlantic current monitoring at risk
This week, Carbon Brief reports on how Trump plans could disrupt efforts to track a major ocean current.
The Irminger Sea, a patch of frigid ocean east of Greenland, plays an outsized role in the Earth’s climate.
Here, surface water that has travelled thousands of kilometres from the tropics grows cold and dense enough to sink to the ocean’s depths – a transformation that must occur for the water to begin a long journey back to the southern hemisphere.
This makes the Irminger Sea an “action centre” for the mighty Atlantic Meridional Overturning Circulation (AMOC), the vast system of ocean currents that keeps temperatures in Europe mild.
Last week, the US government announced plans to dismantle ocean moorings installed in the Irminger Sea which, among other things, collect data on the health of the AMOC.
This came as part of a programme to “descope” the Ocean Observatories Initiative, a $368m network of ocean sensors installed in the Pacific and Atlantic oceans.
Two of the moorings earmarked for removal in the Irminger Sea form part of an internationally funded, trans-Atlantic AMOC monitoring array, known as OSNAP, that stretches from Canada to Scotland.
Experts told Carbon Brief the move by the Trump administration highlights the vulnerability of AMOC observation systems around the world. These deep-sea moorings – scattered across the Atlantic – collect real-time data on, among other things, ocean current, temperature, pressure and biochemistry.
Prof Penny Holliday, chief scientific officer of the UK National Oceanography Centre, told Carbon Brief that the OSNAP array, as well as the RAPID array at 26N, are “entirely dependent” on research grants that have to be “continually reapplied for”.
“Funding is perilous all the time,” she said.
A report prepared last month by scientists for Nordic ministers exploring the security of funding for AMOC observing systems warned that RAPID and OSNAP were in “critical condition” and faced “material exposure over an 18-month horizon”. Meanwhile, other key basin-wide and global components of the global AMOC observing system were rated as “at risk”.
It is not just US funding that is uncertain. The report notes, for example, that the five-yearly funding the UK provides to RAPID and OSNAP is “at risk from 2027 due to year-on-year budget reductions” at the Natural Environmental Research Council.
(RAPID is funded by the US and UK, whereas OSNAP is backed by five different countries, with the US contributing half of the total financial support.)
Report co-author Dr Femke de Jong from the Royal Netherlands Institute for Sea Research told Carbon Brief that “continued AMOC observations” are under pressure in “multiple countries”. She said:
“While the risk of a declining AMOC to society is starting to be recognised, there is not yet a system or institution in place to guarantee a way to monitor it.”
AMOC monitoring arrays are still in their infancy – RAPID, the oldest, was launched in 2004. Two decades of data captured so far shows that the AMOC is slowing down. However, scientists will need many more years of data to be able to confidently link the decline to climate change, rather than natural variability in the ocean.
NOC’s Holliday points to the disconnect between scientific and funder timelines:
“The timescale of observations needed in order to be able to detect a climate change signal from the very naturally variable ocean is around 40-60 years…. [And yet], in the Netherlands, they have to apply for a new grant for their ocean moorings every two years. They are going to have to do that for 40 years.
“This is a very inefficient way of getting funding for what should be critical infrastructure.”
