1.5C looms

1.5C EXAMINED: The run of record heat last year suggests the world is close to exceeding the Paris Agreement’s target of limiting global temperatures to 1.5C above pre-industrial levels, according to two new studies covered by the Press Association. In 2024, annual average temperatures reached 1.5C for the first time. However, the Paris goal is measured as a 20-year average – meaning breaching 1.5C in a single year does not yet show the target has been crossed, the publication noted.

BREACH IN REACH: The first of the two studies “looked at real-world observations of already reached warming levels…and showed that the first single years exceeding each threshold have consistently fallen with the first 20-year period which averaged the same level of warming”, said the newswire. The findings suggest the Paris goal could be crossed within 10 years – unless there are “stringent” emissions cuts, Agence France-Presse reported. This is in-line with recent estimates from the Intergovernmental Panel on Climate Change and Carbon Brief.

HEAT GOES ON: The second study explored what the run of temperatures above 1.5C from July 2023 to June 2024 could mean for the Paris Agreement, the Independent reported. It continued: “The study shows that having 12 consecutive months above 1.5C means there’s a 76% chance that we’ve already hit that long-term warming threshold under current climate policies. If this trend continues for 18 consecutive months, the research says, the breach of the Paris Agreement threshold will be virtually certain. January 2025 was the 19th month to cross that mark.”

Around the world

  • BP SWITCH: According to the Times, BP’s chief executive – under pressure from an activist investor – has pledged to “fundamentally reset” the company’s strategy, which is expected to involve a formal ditching of its target to cut oil and gas output and a further scaling back of its renewables projects.
  • 35% RENEWABLE: Under Indonesia’s new electricity plan, the country aims to increase its renewable energy share from 12% to 35% in 2034 by expanding solar, battery, hydro and geothermal capacity, reported Reuters.
  • ‘EXISTENTIAL THREAT’: A first-of-its kind German government report found that climate change poses an “existential threat” to the European Union due to its “destabilising and unequal” effects, reported Politico.
  • COAL ON A HIGH: As covered by Carbon Brief, China’s construction of coal-fired power plants reached a new 10-year high in 2024, according to a report by the Centre for Research on Energy and Clean Air and Global Energy Monitor.
  • ‘100% SUSTAINABLE WOOD’: The UK government agreed a new deal for the Drax power plant – which burns wood pellets to generate electricity – halving its subsidies and requiring all wood to come from “100% sustainable” sources, the Guardian said. Carbon Brief’s Simon Evans had more details.
  • INDIA DEALS: Reuters reported that Nigeria is seeking assistance from India with its energy transition plans. Meanwhile, BBC News reported on the US and India agreeing a new deal that will see more American oil and gas imported by Delhi.

Latest climate research

  • New research in npj Climate Action showed that the more pronounced local climate change effects become, the stronger the relationship between a person’s education level and their level of “climate concern”.
  • A new study published in Nature Cities showed that people in more disadvantaged neighbourhoods are more exposed to floods, based on studying nearly 45,000 neighbourhoods in eight Latin American countries between 2000 and 2018.
  • Carbon emissions from permafrost “may pose a considerable risk” to climate mitigation efforts, “even if net-zero and negative emissions are achieved”, according to a new study published in Science Advances.

Nearly 95% of countries miss UN climate pledge deadline

Countries meeting a UN deadline to submit 2035 climate pledges by 10 February.

Nearly 95% of countries have missed a UN deadline to submit new climate pledges for 2035, Carbon Brief analysis shows. Just 13 of the 195 parties – highlighted on the map above – signed up to the Paris Agreement published their new emissions-cutting plans, known as “nationally determined contributions” (NDCs), by the 10 February deadline. Countries missing the deadline represent 83% of global emissions and nearly 80% of the world’s economy, according to Carbon Brief analysis. The US submitted its NDC under the previous Biden administration and has now announced plans to withdraw from the Paris Agreement.

From faint idea to ‘forest twice the size of London’

This week, Carbon Brief takes you behind the scenes of its recent rapid analysis on UK airport expansion.

At the end of January, Carbon Brief published an analysis showing that a forest “twice the size of London” would be needed to offset the emissions from the UK government’s proposed airport expansion.

It was covered widely in the press, featured on an ITV current affairs show and was cited twice by MPs in UK parliament.

The analysis – by myself, Carbon Brief’s data scientist, and policy correspondent Josh Gabbatiss – came together in just a few days. Below, I explain how we undertook the rapid analysis.

Heathrow third runway

In January, UK chancellor Rachel Reeves signalled that the UK government was planning to back a third runway at Heathrow airport, along with the expansion of two other London airports, Luton and Gatwick.

We decided to examine what the “climate cost” of such an expansion would be. The UK has so far done little to align its aviation sector with its net-zero target and this seemed like it could make that target even harder to reach.

The question was how should we go about this? Carbon Brief has previously published a guest post showing that airport expansion was not net-zero compatible and others had published more recent emissions analysis. What more could we add?

For a new angle, we wanted to focus on the extra emissions that would result specifically from the expansion of the three airports.

Calculating airport emissions

We noted that Carbon Brief’s guest post had used estimates for the average emissions per passenger to calculate the extra emissions in the year 2050 from the Climate Change Committee (CCC), the UK’s official climate advisers.

But calculating the extra emissions for a single year more than two decades in the future did not feel sufficient because the expansions would be operational years before 2050 – and it is the cumulative that matters for global temperatures.

However, calculating cumulative emissions would require modelling based on airport expansion dates.

Assuming the expansions are fully operational by 2040 and using CCC modelling, I produced the first rough chart (below) using pandas, a data analysis tool designed for the Python coding language.

This showed that the expansion of Heathrow, Luton and Gatwick would produce an extra 81m tonnes of carbon dioxide equivalent (CO2e) by 2050 (in orange on the chart below).

Forest figures

After calculating the extra emissions from the UK’s planned airport expansion, we decided that we needed to come up with a way of contextualising the number for our readers.

This is a common issue for us at Carbon Brief – how to communicate the scale of emissions. The average person does not necessarily know how to interpret 81m tonnes.

It can help to compare it to something more grounded and visible. In this case, we decided to work out how many trees would be needed to absorb all the extra emissions.

First, I redid the analysis with more accurate information on airport-expansion timelines from the Aviation Environment Federation, an NGO focused on the climate impacts of flying, which updated the total to 92m tonnes.

For converting this to trees, I drew on the methods of a previous analysis to get the emissions absorbed per hectare of forest planted over its lifetime.

From this, and assuming that the new forest is planted in 2028, I could calculate the forest area that would need to be planted so that by 2050 it has offset the extra aviation emissions from 2028 to 2050.

Using this, we got a forest “twice the size of Greater London”.

For more context, I added the historical emissions from the aviation sector and separated out each airport’s contribution in the updated chart (below).

Visualising the headline

The last step of the analysis was to present it in Carbon Brief style. I sent the data to our multimedia team and asked them to add two London-shaped forests to the chart.

Armed with the headline and caption text, the multimedia team turned the data into something visually captivating that could tell the story on its own.

Whale Entanglements in Fishing Gear Surge Off U.S. West Coast During Marine Heatwaves

Published

on

New research finds that rising ocean temperatures are shrinking cool-water feeding grounds, pushing humpbacks into gear-heavy waters near shore. Scientists say ocean forecasting tool could help fisheries reduce the risk.

Each spring, humpback whales start to feed off the coast of California and Oregon on dense schools of anchovies, sardines and krill—prey sustained by cool, nutrient-rich water that seasonal winds draw up from the deep ocean.

Key developments

Food inflation on the rise

DELUGE STRIKES FOOD: Extreme rainfall and flooding across the Mediterranean and north Africa has “battered the winter growing regions that feed Europe…threatening food price rises”, reported the Financial Times. Western France has “endured more than 36 days of continuous rain”, while farmers’ associations in Spain’s Andalusia estimate that “20% of all production has been lost”, it added. Policy expert David Barmes told the paper that the “latest storms were part of a wider pattern of climate shocks feeding into food price inflation”.

NO BEEF: The UK’s beef farmers, meanwhile, “face a double blow” from climate change as “relentless rain forces them to keep cows indoors”, while last summer’s drought hit hay supplies, said another Financial Times article. At the same time, indoor growers in south England described a 60% increase in electricity standing charges as a “ticking timebomb” that could “force them to raise their prices or stop production, which will further fuel food price inflation”, wrote the Guardian.

TINDERBOX’ AND TARIFFS: A study, covered by the Guardian, warned that major extreme weather and other “shocks” could “spark social unrest and even food riots in the UK”. Experts cited “chronic” vulnerabilities, including climate change, low incomes, poor farming policy and “fragile” supply chains that have made the UK’s food system a “tinderbox”. A New York Times explainer noted that while trade could once guard against food supply shocks, barriers such as tariffs and export controls – which are being “increasingly” used by politicians – “can shut off that safety valve”.

El Niño looms

NEW ENSO INDEX: Researchers have developed a new index for calculating El Niño, the large-scale climate pattern that influences global weather and causes “billions in damages by bringing floods to some regions and drought to others”, reported CNN. It added that climate change is making it more difficult for scientists to observe El Niño patterns by warming up the entire ocean. The outlet said that with the new metric, “scientists can now see it earlier and our long-range weather forecasts will be improved for it.”

WARMING WARNING: Meanwhile, the US Climate Prediction Center announced that there is a 60% chance of the current La Niña conditions shifting towards a neutral state over the next few months, with an El Niño likely to follow in late spring, according to Reuters. The Vibes, a Malaysian news outlet, quoted a climate scientist saying: “If the El Niño does materialise, it could possibly push 2026 or 2027 as the warmest year on record, replacing 2024.”

CROP IMPACTS: Reuters noted that neutral conditions lead to “more stable weather and potentially better crop yields”. However, the newswire added, an El Niño state would mean “worsening drought conditions and issues for the next growing season” to Australia. El Niño also “typically brings a poor south-west monsoon to India, including droughts”, reported the Hindu’s Business Line. A 2024 guest post for Carbon Brief explained that El Niño is linked to crop failure in south-eastern Africa and south-east Asia.

News and views

  • DAM-AG-ES: Several South Korean farmers filed a lawsuit against the country’s state-owned utility company, “seek[ing] financial compensation for climate-related agricultural damages”, reported United Press International. Meanwhile, a national climate change assessment for the Philippines found that the country “lost up to $219bn in agricultural damages from typhoons, floods and droughts” over 2000-10, according to Eco-Business.
  • SCORCHED GRASS: South Africa’s Western Cape province is experiencing “one of the worst droughts in living memory”, which is “scorching grass and killing livestock”, said Reuters. The newswire wrote: “In 2015, a drought almost dried up the taps in the city; farmers say this one has been even more brutal than a decade ago.”
  • NOUVELLE VEG: New guidelines published under France’s national food, nutrition and climate strategy “urged” citizens to “limit” their meat consumption, reported Euronews. The delayed strategy comes a month after the US government “upended decades of recommendations by touting consumption of red meat and full-fat dairy”, it noted. 
  • COURTING DISASTER: India’s top green court accepted the findings of a committee that “found no flaws” in greenlighting the Great Nicobar project that “will lead to the felling of a million trees” and translocating corals, reported Mongabay. The court found “no good ground to interfere”, despite “threats to a globally unique biodiversity hotspot” and Indigenous tribes at risk of displacement by the project, wrote Frontline.
  • FISH FALLING: A new study found that fish biomass is “falling by 7.2% from as little as 0.1C of warming per decade”, noted the Guardian. While experts also pointed to the role of overfishing in marine life loss, marine ecologist and study lead author Dr Shahar Chaikin told the outlet: “Our research proves exactly what that biological cost [of warming] looks like underwater.” 
  • TOO HOT FOR COFFEE: According to new analysis by Climate Central, countries where coffee beans are grown “are becoming too hot to cultivate them”, reported the Guardian. The world’s top five coffee-growing countries faced “57 additional days of coffee-harming heat” annually because of climate change, it added.

Nature talks inch forward

This week, Carbon Brief covers the latest round of negotiations under the UN Convention on Biological Diversity (CBD), which occurred in Rome over 16-19 February.

The penultimate set of biodiversity negotiations before October’s Conference of the Parties ended in Rome last week, leaving plenty of unfinished business.

The CBD’s subsidiary body on implementation (SBI) met in the Italian capital for four days to discuss a range of issues, including biodiversity finance and reviewing progress towards the nature targets agreed under the Kunming-Montreal Global Biodiversity Framework (GBF).

However, many of the major sticking points – particularly around finance – will have to wait until later this summer, leaving some observers worried about the capacity for delegates to get through a packed agenda at COP17.

The SBI, along with the subsidiary body on scientific, technical and technological advice (SBSTTA) will both meet in Nairobi, Kenya, later this summer for a final round of talks before COP17 kicks off in Yerevan, Armenia, on 19 October.

Money talks

Finance for nature has long been a sticking point at negotiations under the CBD.

Discussions on a new fund for biodiversity derailed biodiversity talks in Cali, Colombia, in autumn 2024, requiring resumed talks a few months later.

Despite this, finance was barely on the agenda at the SBI meetings in Rome. Delegates discussed three studies on the relationship between debt sustainability and implementation of nature plans, but the more substantive talks are set to take place at the next SBI meeting in Nairobi.

Several parties “highlighted concerns with the imbalance of work” on finance between these SBI talks and the next ones, reported Earth Negotiations Bulletin (ENB).

Lim Li Ching, senior researcher at Third World Network, noted that tensions around finance permeated every aspect of the talks. She told Carbon Brief:

“If you’re talking about the gender plan of action – if there’s little or no financial resources provided to actually put it into practice and implement it, then it’s [just] paper, right? Same with the reporting requirements and obligations.”

Monitoring and reporting

Closely linked to the issue of finance is the obligations of parties to report on their progress towards the goals and targets of the GBF.

Parties do so through the submission of national reports.

Several parties at the talks pointed to a lack of timely funding for driving delays in their reporting, according to ENB.

A note released by the CBD Secretariat in December said that no parties had submitted their national reports yet; by the time of the SBI meetings, only the EU had. It further noted that just 58 parties had submitted their national biodiversity plans, which were initially meant to be published by COP16, in October 2024.

Linda Krueger, director of biodiversity and infrastructure policy at the environmental not-for-profit Nature Conservancy, told Carbon Brief that despite the sparse submissions, parties are “very focused on the national report preparation”. She added:

“Everybody wants to be able to show that we’re on the path and that there still is a pathway to getting to 2030 that’s positive and largely in the right direction.”
