Offshore wind off track

EMPIRE WIND 2: Energy majors BP and Equinor have terminated their power agreement with the state of New York to build a 1.26 gigawatt offshore wind farm, according to Bloomberg. The deal for the 147 turbine wind farm, 15 miles south of New York’s Long Island was signed in 2022, for a strike price of $107.50 per megawatt-hour, the Financial Times noted. 

WIND WOES: BP and Equinor pointed to the “unforeseeable economic forces” – including inflation stemming from the war in Ukraine and Covid-19, supply chain bottlenecks and interest rate increases, along with permitting delays – which affected the “financial attractiveness” of the project, the FT added. Offshore wind developers have cancelled contracts to sell power in Massachusetts, Connecticut and New Jersey, as well as threatening to cancel agreements in other states, as project costs rise, Reuters reported. 

VINEYARD WIND: Meanwhile, the first turbine in the Vineyard offshore wind development began generating power this week, delivering around 5 megawatts of power to the New England grid, the Guardian reported. Vineyard Wind is the first US large-scale offshore wind project, and is expected to have 62 turbines in total when complete. 

UK’s second-warmest year

SECOND WARMEST: Data from the Met Office shows that 2023 was the UK’s second-warmest year of record, and the warmest year on record for Wales and Northern Ireland, BBC News reported. The average absolute temperature for last year was 9.97C, only slightly lower than the 10.02C recorded in 2022 – the warmest year on record for the UK – according to the Guardian. 

TOP 10: The UK’s 10 warmest years have all occurred since 2003, the Guardian noted, with Met Office scientists emphasising that  “such a warm year would have occurred only once in 500 years without human-caused global heating”. The news comes as heavy flooding driven by Storm Henk has hit the UK, with more than 550 flood warnings and alerts in place in England and Wales and hundreds of homes flooded, the Guardian reported.

REPEAT RECORDS: While 2023 is expected to be announced as the warmest on record in the coming weeks, the contributing factors that made it so warm will likely “push the dial even further in 2024”, New Scientist reported. The El Niño climate pattern in the Pacific Ocean is expected to reach its full strength – on top of warming driven by greenhouse gases – next year, it noted.

Around the world

• GERMAN EMISSIONS: Germany’s carbon dioxide emissions fell to their lowest level since the 1950s in 2023, due to less coal-fired power and a reduced output by energy-intensive industries, reported Reuters, but the decline is “unsustainable without climate policy changes”. 
• OVERTAKING TESLA: Chinese firm BYD has knocked Elon Musk’s company “off the top spot” to become the world’s best-selling electric vehicle manufacturer for the first time, according to the Financial Times.
• COP29 PRESIDENT: Azerbaijan has appointed environmental minister Mukhtar Babayez as president of the COP29 climate talks, reported Climate Home News. Babayez is the former head of the country’s state-owned oil and gas company Socar.
• LOW-CARBON HYDROGEN: The US government has unveiled a new framework to support the production of low-carbon hydrogen, offering tax credits based on the life-cycle greenhouse gas emissions from the power source used in hydrogen production, according to Reuters.
• ‘POSTCODE LOTTERY’: Analysis of the 20 costliest climate disasters of 2023 has shown that “countries less able to rebuild or who have contributed least to climate crisis suffer worst”, reported the Guardian.
• PIPELINE PRACTICES: French energy giant TotalEnergies has launched a review of its land acquisition practices for the controversial $10bn East African crude oil pipeline in Uganda and Tanzania, Agence France-Presse reported.

324tn yuan

China will need to spend around 324tn yuan ($45.5tn), roughly 2.7 times its GDP in 2022, to realise its climate targets of peaking CO2 emissions before 2030 and going carbon neutral before 2060, reported China Daily.

Latest climate research

• Diversifying agricultural production in sub-Saharan Africa towards more micronutrient-rich foods is “necessary” to provide an adequate nutrient supply under increasing climate risks and population growth, according to a new study published in Nature Food. 
• Using a large-scale experiment on Facebook, a new paper in Climatic Change found “little to no support” for the fear that attention on solar radiation management or carbon dioxide removal “might crowd out the desire to cut emissions”.
• The genes of an Antarctic octopus provide “empirical evidence” that the West Antarctic ice sheet previously “collapsed when the global mean temperature was similar to that of today”, warned a new study in Science, suggesting “the tipping point of future WAIS collapse is close”.

Captured

Last year, the UK’s electricity from fossil fuels dropped to its lowest level since 1957, new analysis from Carbon Brief reveals. The amount of electricity from fossil fuels fell 22% year-on-year in 2023, to 104 terawatt hours (TWh), its lowest level in 66 years. Back then,  Harold Macmillan was the UK prime minister and the Beatles’ John Lennon and Paul McCartney had just met for the first time. The chart above shows the fall of fossil fuels in the electricity mix, to meet just 33% of electricity needs in 2023, while renewable energy generation continues to surge.

Spotlight

Carbon Brief’s top five articles of 2023

Carbon Brief takes a look at its top five most-read stories published in 2023. 

Factcheck: 21 misleading myths about electric vehicles 

Carbon Brief’s most-read new article of 2023 was a factcheck by deputy editor Dr Simon Evans of 21 of the most common misleading myths about electric vehicles (EVs). The article explored claims often seen in the press, such as EVs having to travel more than 50,000 miles for their emissions to break even with a conventional car, EVs having little or no CO2 advantage over a car someone already drives, and sales of EVs appearing to be slowing. 

As Evans explained, the sales of EVs have continued to surge in the UK and globally, as the vehicles become cheaper, charging infrastructure more widespread and bans on combustion engines loom closer. Despite this growth, EVs are still subject to “relentless hostile reporting across mainstream media in many major economies, including the UK”, Evans noted.

COP28: Key outcomes agreed at the UN climate talks in Dubai 

At COP28 in Dubai, nearly every country in the world agreed to “transition away from fossil fuels” within the global stocktake – the first time fossil fuels have been explicitly mentioned in the 28 years of international climate negotiations.

Ten of Carbon Brief’s journalists attended the two-week event and pulled together this mammoth summary – covering everything from the significant loss-and-damage fund on the first day to the gritty negotiations around Article 6 and a just transition. 

Analysis: Which countries have sent the most delegates to COP28? 

More than 97,000 badges were issued for COP28 in Dubai, almost twice the number of participants that travelled to Sharm El Sheikh in Egypt in 2022. In Carbon Brief’s third most-read article of 2023, senior science editor Robert McSweeney detailed who registered for COP28, including 24,488 delegates representing parties, 14,338 observers from NGOs and 3,972 media delegates. 

Analysis: China’s emissions set to fall in 2024 after record growth in clean energy 

China’s carbon dioxide emissions are set to fall in 2024, according to analysis for Carbon Brief by Lauri Myllyvirta, lead analyst and co-founder of the Centre for Research on Energy and Clean Air (CREA). Myllyvirta explained how China’s emissions “could now be facing structural decline due to record growth in the installation of new low-carbon energy sources”. This came despite CO2 emissions rising 4.7% year-on-year in the third quarter of 2023 as they continued to rebound following China’s “zero-Covid” period.

Analysis: How low-sulphur shipping rules are affecting global warming

Rounding out the list of Carbon Brief’s top five most-read articles of 2023, is an analysis of how new international rules to reduce air pollution from shipping could affect the climate. The article – by Dr Zeke Hausfather, climate science contributor for Carbon Brief, and Prof Piers Forster, professor of climate physics at the University of Leeds – found that the new regulations, imposed in 2020, will likely add 0.05C to global temperatures by 2050. 

Watch, read, listen

DOCUMENTING DROUGHT: A Guardian article explored the images Maasai photographers Claire Metito and Irene Naneu have been using to chronicle the everyday experiences of two elderly women in Esiteti in southern Kenya, where a prolonged drought has made life more challenging for women in pastoralist communities.
