The Russian government’s campaign for endorsement of “transitional fuels” succeeded at the Cop28 climate talks in Dubai.

Russia, the world’s second biggest gas producer, told the United Nations back in February that “natural gas as a transitional fuel… can be used for [emission-cutting] purposes” and this should be recognised at Cop28.

While the final Cop28 agreement does not specifically mention gas, it “recognizes that transitional fuels can play a role in facilitating the energy transition while ensuring energy security”.

It also calls on governments to transition away from fossil fuels in their energy systems so as to achieve net zero by 2050.

Diann Black-Layne from Antigua and Barbuda told the closing meeting of Cop28 that the “transitional fuel” language “is a dangerous loophole”. Coal, oil and gas are all fossil fuels and “we need to transition away from them,” she said.

But Barbados’s climate envoy Avinash Persaud later told Climate Home: “If you actually think about transitioning grids, transition fuels would help to transition with the lowest emissions. You can’t flip a switch and so in the mean time half switch. The challenge is to make sure that the slip road doesn’t become a parking lot.”

Persaud said that “more than a few” countries had supported the language “at some level and at varying degrees”. Another negotiator agreed it “wasn’t just Russia”.

Last-minute addition

Ahead of Cop28, governments and other organisations told a UN panel what they wanted to do to put the world on track to meet its climate goals, in a process known as the global stocktake.

A team of technical experts summarised all the submissions in October. The head of UN climate change, Simon Stiell, called for a “course correction”.

The technical summary included a line which called on governments to “recognise role of natural gas as an efficient transitional fuel”.

At Cop28, the UAE Presidency put together a 27-page document which included the language which made it into the final text, dropping the mention of gas but referring to “transitional fuels”.

Like many other parts of this document, it included an alternative option of no text. Three days later, after talking to governments, the UAE Presidency dropped it from their next version of the Dubai deal.

With all the attention on the broader issue of fossil fuel phase-out, this language was little noticed or commented on – either in the press or by negotiators.

It stayed off the radar until the scheduled end date for Cop28, 12 December. It appeared in a draft text, according to a source who saw the text, time-stamped 8pm that night.

But some negotiators didn’t see it until the text was published at 7am the following morning. Four hours later, the closing plenary meeting began and within minutes it had been approved.

‘An honest paragraph’

The strongest supporters of anti-fossil fuel language at Cop28 were developed nations, particularly the European Union, and small islands.

But on gas, developed countries did not want to resist, and small islands were still in a separate meeting room discussing the text when the decision was made.

Speaking to press shortly afterwards, German foreign minister Annalena Baerbock said the EU delegation had not had much time to discuss the text.

But, she said through a translator, “for me it is really an honest paragraph”. She said Germany and the EU have been accused of hypocrisy at previous Cops for continuing to use gas while asking other countries to move to renewables.

“We wanted to show that this does not happen from one day for another but it will happen slowly, slowly, slowly,” she said. Gas is “a bridge”, she said, and “every bridge has an end”.

Kaveh Guilanpour, from the Center for Climate and Clean Energy Solutions, said he’d rather the language had not been there “but in many ways its consistent with what lot of countries and regions are actually doing”.

The day before Cop28 closed, Brazil auctioned 193 oil and gas blocks. On the day it closed, the Italian export credit agency lent €400m ($436m) to a firm to supply Italy with gas. The day after, the board of a European public bank decided to keep lending to gas pipelines and power plants.

Small islands not there

The negotiating group for 39 small, developing island states (Aosis) was most likely to object to that language.

But, having seen the final text at 7am, when the plenary started they were still frantically discussing whether to support it or not.

As they entered the room with their comments on the text in hand, the room was already standing to applaud Cop28 president Sultan Al-Jaber’s announcement that it had been adopted.

Their lead negotiator Anne Rasmussen from Samoa took the microphone to say she “was a little confused about what happened”.

Delivering her prepared remarks, she said that because of the transitional fuels language – and other issues – that the “course correction has not been secured”.

“We have made incremental advancements over business as usual when what we really needed is an exponential step change,” she said.

To a standing ovation, she said the text includes a “litany of loopholes” for carbon capture and on the removal of fossil fuel subsidies.

Heatwaves driving recent ‘surge’ in compound drought and heat extremes

Published

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:
