An essential guide to the week’s key developments relating to climate change.

This week

Africa’s second climate summit

‘NOT CHARITY’: At the second Africa climate summit held in Addis Ababa in Ethiopia this week, leaders “chastised developed nations for failing to honor [climate finance] pledges” and said they will “tap the private sector” to help fill the gap, Bloomberg reported. In a joint statement, African leaders said that providing climate finance is “a legal obligation and not charity, as anchored in the UN Framework Convention on Climate Change and its Paris Agreement”, according to the outlet.

SOLUTIONS CENTRED: Climate Home News reported that Ethiopian president Taye Atske Selassie told the closing ceremony on Wednesday the summit had repositioned Africa “not as victims of a crisis it never created but as a global centre for climate solution, renewable energy and green growth”. The outlet added that the joint leaders’ declaration called for “strengthened and sustained support” to scale up African-led climate initiatives, such as the 8,000km Great Green Wall across the Sahel and the African Forest Landscape Restoration Initiative.

Around the world

  • ‘SILLY’: Chris Wright, the climate-sceptic US energy secretary, has dismissed the impacts of climate change as “not incredibly important” and described the Paris Agreement as “silly”, reported the New York Times. Elsewhere, the group of “climate contrarians” behind Trump’s misleading climate report have been “disbanded” following a lawsuit challenging their appointment, CNN reported.
  • CHINA BOOM: The world’s fossil-fuel use could begin to drop by 2030 as a result of China’s “rapid adoption of renewables and its increasing reliance on electricity”, Bloomberg reported, citing a new study by thinktank Ember.
  • NDC INDECISION: EU member states are still “wrangling” over the bloc’s overdue 2035 climate target, “with no sign of agreement”, according to a leaked draft text seen by the Guardian.
  • TRADE SPOTLIGHT: Brazil plans to propose a new forum for governments to discuss how climate policy affects trade at the next World Trade Organization meeting next week, according to Reuters.
  • UK PUBLIC POLLED: In a frontpage story, the Times covered new polling it commissioned, reporting that the number of people who think the dangers of global warming are exaggerated has increased by more than 50% in the past four years, from 16% to 25%. [Polling experts have criticised the framing of the Times coverage, noting that a large majority of the public still back net-zero.] 

£797 million

The record amount of UK climate aid spent on nature last year – largely due to an increase in spending on carbon offsets, according to new Carbon Brief analysis.

Global map showing that more than 200 'major' heatwaves have been recorded around the world in the 21st century

A new study used “extreme event attribution” to assess the impact of climate change on all 21st-century heatwaves that were classified as “major disasters”. It found that global warming linked to the world’s biggest 180 oil and gas companies made all 213 heatwaves analysed more intense and frequent. Meanwhile, one-quarter of the heatwaves would have been “virtually impossible” without human-caused global warming. The paper, covered by Carbon Brief, analysed 213 heatwaves over 2000-23 that were recorded in the EM-DAT database of “major disasters” . These heatwaves are shown in the map above.

How scientists can tackle net-zero backlash

This week, Carbon Brief asks climate scientists attending a summit at the University of East Anglia, UK how researchers can better combat net-zero misinformation.

It comes as the UK’s right-wing political parties and press are increasingly making misleading claims about net-zero.

Asher Minns, executive director of the Tyndall Centre for Climate Change Research at the University of East Anglia

The whole discourse around net-zero has become something that it was never intended to be. It’s a quite specific scientific concept that came out of the IPCC 1.5C report, following up on [the] Paris [Agreement], so it actually has quite a specific definition, but it has actually become a phrase that is being used really just to mean “removing CO2” or “saving energy”, even. It’s become this kind of huge term across public, across media, across policy, that everybody can just pin what they mean to “net-zero” without actually referring to what it actually is, which is absolute zero emissions, getting CO2 out of the atmosphere. The fact that there is a government department called “net-zero” isn’t great for that public discourse, for public understanding, and that’s why we’ve got a bit of a backlash. I don’t think we need to necessarily abandon the phrase net-zero, but I think we should just talk about clean energy and concepts that people have a chance of hanging onto, rather than something that’s really quite difficult.

Prof Corinne Le Quéré, Royal Society research professor of climate change science at the University of East Anglia

I think narratives about the way that we present climate action can be very negative, and, in fact, we do climate action all the time. We’ve cut emissions by half in the UK and most people haven’t realised that this is happening. Just talking about climate change in the way that there are things that you can do that are desirable and have benefits for you. Of course, the government needs to make climate solutions accessible to everybody. But improving the narratives about how we talk about climate change, that would be, for me, a small thing that we could do.

Prof Hayley Fowler, professor of climate change impacts at Newcastle University

I don’t think we can do it alone. I think we try to do everything alone and I don’t think that’s the right approach. My personal opinion is we need to be collaborating with key influencers and celebrities, quite honestly, who can actually get that message across to the people who need to hear that message. I think we need probably a few key spokespeople. And I don’t think they should be scientists, but they should have simple and clear scientific messages that they convey. There’s lots of misinformation and it’s conveyed in very clear ways with simple messaging. Often climate science is really, really complicated and that’s why people just don’t understand it, they don’t understand the jargon surrounding it and, therefore, perhaps they are more likely to understand the simple messages that come from the climate deniers.

Dr Ruth Wood, senior lecturer in environment and climate change at the University of Manchester

I find it quite challenging to work out how to engage in those discussions because they’re taking place in forums that I’m not at. Do we need a groundswell of voices around supporting net-zero, which have the same level of media savviness of the anti net-zero groups? If we had their same ability to mobilise and get the message out there, maybe that would counter some of their narratives. The gap between science and communication is a huge challenge.

Prof Charlie Wilson, professor of energy and climate change and senior research fellow in the Environmental Change Institute at the University of Oxford

I guess that part of the answer is how we’ve always done it, which is forceful rebuttals and corrections with appropriate evidence. The second bit is like learning how the algorithms work to promote both information, as well as misinformation. This misinformation is being amplified by algorithmic preferences expressed through social media platforms, which emphasise juicy clickbait-type stuff.

Watch, read, listen

FIXING TOMORROW: Climate scientist Dr Kimberly Nicholas and the NGO Project Drawdown released an evidence-based online guide for how individuals can take actions to address climate change.

‘WAR ON SCIENCE’: Bloomberg had a special feature on how Donald Trump’s “war on science” is crippling the US.

CLIMATE IN COURT: The New York Times unpacked how and why a group of students from the Pacific Islands took a climate case to the International Court of Justice.

The Land Came First

An older teaching about land acknowledgement

As I have come to understand the spirit and intention of land acknowledgement, I often return to fond memories of my grandmother and her words of wisdom. She taught that the health of the places we call home comes first, because the wellbeing of the people depends on it.

In her teaching, land acknowledgement began with the land. Long before it became a paragraph read at the start of a meeting, it was a way of recognizing a homeland: its waters, its species, its seasons, and the spirit that revealed whether the place was well.

Her teaching echoes a practice found across many Indigenous Nations. Haudenosaunee gatherings, for example, have long opened with the Ohén:ton Karihwatéhkwen, the Thanksgiving Address, often translated as “the words that come before all else.” The speaker greets and gives thanks to the people, the earth, the waters, the plants, the animals, the winds, the sun, the moon and the stars. Only after everything that sustains life has been acknowledged does the gathering turn to its own business.

That order changes what an acknowledgement is for. Its purpose was to share the story of a place with neighbours and to draw them into the work of tending it. People entered the story second, as the ones responsible for what had just been named.

Understood this way, an acknowledgement does more than open a meeting. It asks us to reconsider where we stand, and what we owe the ground beneath us.

Nations among nations

In her teaching, people are one nation among many. The salmon are a nation. So are the cedars, the bison, the medicine plants, and the pollinators. Each belongs to a place, carries its own responsibilities, and offers gifts no other nation can give.

This idea of kinship runs through many Indigenous philosophies. The phrase “all my relations,” heard in ceremonies and gatherings across Turtle Island, is a reminder that family extends beyond people to the animals, plants, waters and lands that make life possible. Some Indigenous languages carry the same understanding in their grammar, speaking of many plants, animals and natural forces as living beings rather than objects.

Sovereignty, understood through this relationship, is a kind of standing more than a form of control. Each nation belongs fully to its place and carries its share of that place’s life. No nation thrives alone, and none thrives by taking over the whole.

The land is also the source of instruction. Over generations, people watched how a river valley or a stretch of prairie kept itself well: who arrived when, who fed whom, and how much could be taken before the giving stopped. In my grandmother’s telling, those observations became instructions, and those instructions helped shape law and protocol. They guided when to harvest, where to camp, how to enter a neighbour’s territory, and what was owed in return.

Indigenous legal scholars today often describe this as law that comes from the land itself, learned by watching how living systems sustain one another. A plainer name for it is knowing how to live somewhere.

The host and the guest

One of the clearest teachings in this understanding of the world is the relationship between host and guest. My grandmother invited us to recognize that relationship in the lives of plants and animals.

A host prepares the place before anyone arrives. A beaver family dams a stream, and the pond becomes a home for fish, frogs, birds and plants. A fallen tree becomes a nurse log, feeding the next generation of seedlings as it returns to the soil.

A host offers first. A flowering plant sets out nectar. A berry bush ripens fruit. These provisions come in their own season, not whenever a visitor happens to want them.

A host also makes its presence known. Birdsong, scent and the marks left along a trail tell newcomers that a place is already inhabited. The visitor does not arrive in an empty world.

The guest has responsibilities too. A guest attends to the season and to what the place can offer. A guest does not assume that everything within reach is theirs to take. A guest leaves something that helps sustain the relationship.

A bee takes nectar and carries pollen. Read through this teaching, that exchange offers an image of visiting well: receiving a gift while helping the host continue its life.

Many Indigenous harvesting protocols carry the same ethic into daily practice: ask before taking, take only what is needed, offer thanks, and leave enough for others and for the plant or animal to recover.

None of this suggests that every relationship in nature is peaceful or generous. These are ways of seeing responsibilities that people can learn to carry.

Everyone is both

No being is only a host or only a guest.

A tree makes room for other life while depending on soil, water, sunlight, fungi, and relationships beyond itself. People, too, may welcome others into their homes while remaining dependent on the larger homeland that sustains them.

The distinction between host and guest is therefore about roles, not ranks. Everyone receives. Everyone has something to give.

The question is whether the exchange sustains the place.

A visitor who takes without restraint leaves less for those who come next. A host who neglects the place has less to offer. Both have responsibilities, and neither can fulfil them alone.

This is the heart of reciprocity, a principle found across Indigenous philosophies: relationships stay healthy when gifts move in both directions. The Haudenosaunee teaching of the seventh generation extends that exchange across time, asking that decisions made today leave the place well for those not yet born.

Mutual benefit begins here, with the recognition that different beings carry different gifts and obligations.

What people carry forward

My grandmother’s teaching connects these relationships to the ways people meet their neighbours.

The host prepares a place, offers food and rest, and explains where the visitor has arrived. The guest makes themselves known, explains why they have come, listens to the terms of the visit, and brings something in return. The gift may be material. It may also be labour, knowledge, news, or a commitment to help.

Nations around the Great Lakes carried this ethic into treaty. The Dish with One Spoon, an agreement among the Haudenosaunee, Anishinaabe and allied Nations, describes shared hunting grounds as a single dish. Everyone eats from it with one spoon, takes only what they need, leaves enough for others, and keeps the dish clean. The Two Row Wampum, between the Haudenosaunee and European newcomers, shows two vessels travelling side by side on the same river, each keeping its own ways and neither steering the other.

In this understanding, acknowledgement is more than naming the people associated with a territory. It is learning enough about a homeland to behave responsibly within it.

Whose home is this? What sustains it? What laws and agreements guide our presence? What can we receive, and what must we return?

These questions make acknowledgement a relationship rather than a recital.

They also make it diplomatic. A guest who recognizes the host’s homeland recognizes that they have entered a place with its own relationships and responsibilities. A host who welcomes the guest makes room for an encounter governed by those relationships.

Neither arrives without standing. Neither arrives without obligations.

Beginning with place

I write from the shores of the Bay of Quinte. Here, the teaching asks me to begin with the water, the shoreline, and the life they sustain. Before I describe myself, I must attend to where I am.

That does not make people or history less important. It places them within the homeland that gives them meaning. The people, their laws, their agreements, and their responsibilities all belong to the place.

In a time of longer fire seasons, troubled waters, and uncertainty about what the next season will bring, this teaching asks something difficult and useful of us: pay attention before you speak.

An acknowledgement cannot tell the story of a place if the speaker has stopped noticing it.

The land came first. Beginning there again means learning to name what sustains us, and accepting that what sustains us also asks something of us.

Carbon dioxide (CO2) emissions from fossil fuels and cement are projected to fall by around 0.4% in 2026 to 38.2bn tonnes of CO2 (GtCO2), according to new figures from the Global Carbon Project.

The 21st edition of the annual “global carbon budget” report, published today, says that this small decline is largely due to a 1.9% drop in emissions from oil and the energy shock triggered by the
