Antarctic sea ice is “behaving strangely” and might have entered a “new regime”, the director of the US National Snow and Ice Data Centre (NSIDC) tells Carbon Brief.
Following an all-time low maximum in September 2023, Antarctic sea ice has been tracking at near-record-low extent for the past six months. Last month, it hit its 2024 minimum extent, tying with 2022 for the second-lowest Antarctic minimum in the 46-year satellite record.
Dr Mark Serreze, director of the NSIDC tells Carbon Brief that more warm ocean water is reaching the surface to melt ice and keep it from forming. He says that we “must wait and see” whether this is a “temporary effect” or whether the Antarctic has entered a “new regime”.
Meanwhile, Arctic sea ice has reached its maximum extent for the year, peaking at 15.01m square kilometres (km2) on 14 March. The provisional data from the NSIDC shows that this year’s Arctic winter peak, despite favourable winds that encouraged sea ice formation, was 640,000km2 smaller than the 1981-2010 average maximum.
This year’s maximum was the 14th lowest in the satellite record.
“Overall, the road remains downhill for Arctic sea ice, but it is quite bumpy along the way,” another scientist tells Carbon Brief. This relatively high winter peak is “notable and a good reminder that we have to communicate and account for this type of weather variability when we talk about Arctic climate change”, he says.
He adds that although the maximum is high compared to recent years, the ice is still “much thinner” than it was a few decades ago. The “wide coverage of this thinner ice” means total Arctic sea ice volume for the month of February was the third lowest on record.
Arctic winter peak
Arctic sea ice extent changes throughout the year. It grows each winter before reaching its peak for the year in February or March and then melts throughout the spring and summer towards its annual minimum, typically around September.
Using satellite data, scientists can track the growth and melt of sea ice, allowing them to determine the size of the ice sheet’s winter maximum and summer minimum extent. These are key metrics to monitor the “health” of the Arctic sea ice.
The NSIDC’s announcement says that this year’s Arctic winter peak of 15.01m is “below average”. Clocking in at 640,000km2 below the 1981-to-2010 average maximum extent, it ranks as the 14th lowest in the satellite record.
The NSIDC adds that the date of the maximum this year, 14 March, was two days later than the 1981-to-2010 average date of 12 March.
The plot below shows Arctic sea ice extent on 14 March, with the average sea ice extent for 1981-2010 shown by the orange line.
Arctic freeze
“The road remains downhill for Arctic sea ice, but it is quite bumpy along the way,” Dr Zack Labe – a postdoctoral researcher working at NOAA Geophysical Fluid Dynamics Laboratory and the atmospheric and oceanic sciences programme at Princeton University – tells Carbon Brief. He adds:
“While this winter was yet again consistent with the long-term trend toward a warmer Arctic with less ice, regional weather patterns can still contribute to ice expansion and slower net declines, especially if the winds align from a north-to-south direction.”
Arctic sea ice reached its minimum extent for 2023 on 19 September.
With an extent of 4.23m km2, this was the sixth-lowest minimum on record and 1.99m km2 below the average minimum recorded over 1981-2010.
Following its annual minimum, Arctic sea ice growth was “slower than average”, leading to the fifth-lowest September on record, according to the NSIDC.
Labe tells Carbon Brief that the freeze season started with “widespread open water across the Pacific side of the Arctic, with massive areas of ice missing north of Alaska”, which contributed to “well-above-average temperatures” in the region.
Throughout October, however, sea ice extent increased by 119,800km2 per day – faster than the 1981-2010 average of 89,200km2 per day, according to the NSIDC.
The Arctic freeze up was “particularly rapid” in the seas around Siberia. By the end of October, the ice cover had reached the Siberian coast, although open water remained in the Beaufort and Chukchi Seas.
Air temperatures over the Arctic Ocean, around 2,500 feet above surface level, were mostly above average during October – particularly in and around the Canadian Archipelago, which saw temperatures of 4-5C above average.
Labe tells Carbon Brief that, overall, the Arctic winter can be characterised by “unusual warmth in the northern Arctic, but greater total ice extent”. This “counterintuitive” dynamic was caused by atmospheric circulation patterns, which led to “warmer, moist air blowing toward the north pole, while northerly winds contribute to expanding ice in the Greenland Sea and Sea of Okhotsk”, he says.
Throughout November, Arctic sea ice extent continued to increase faster than average. However, the NSIDC says the freeze up “temporarily stalled” for around five days from 22 November, as a series of three tropical cyclones brought warm, moist air into the north Atlantic.
The NSIDC says that a combination of low pressure to the north and west of Svalbard and a high-pressure centre to the south-east “created a strong, persistent flow from the south of relatively warm and moist air from the north Atlantic Ocean toward Svalbard”.
This flow of air can be seen as “an extension of an atmospheric river into the Arctic”, it says. It adds that the strong winds “helped to push the ice edge in the east Greenland and Barents seas northwards, limiting new ice formation”.
The NSIDC notes that pauses in Arctic sea ice freeze up have happened in November before, in 2013 and 2016, making such events “rare, but not unknown”.
Arctic sea ice extent continued to increase “markedly faster” than usual throughout December, the NSIDC says. It adds that “sea ice formation in Hudson Bay was unusually late, but the ice cover expanded quickly from west to east in mid-December”.
For December overall, 2023 saw the third-highest monthly gain on record, with 2.71m km2 of sea ice extent added throughout the month. Average Arctic sea ice extent over December 2023 was the ninth lowest in the satellite record, at 12m km2.
Arctic sea ice extent continued to move down the rankings as the new year rolled in, despite slower-than-average ice growth. In fact, the NSIDC says that Arctic sea ice extent actually declined for a few days at the end of the month, although it notes that this is “not unusual at this time of year” and says it is “caused by weather systems that temporarily halt ice growth or push the ice northwards”.
The average Arctic sea ice extent for January 2024 was 13.92m km2 – the 20th lowest on record.
This comparatively high sea ice extent is “notable and a good reminder that we have to communicate and account for this type of weather variability when we talk about Arctic climate change”, Labe tells Carbon Brief.
Arctic sea ice extent continued to grow throughout February, gaining 15.3m km2 of ice throughout the month. The February 2024 extent of 14.61m km2 was 690,000km2 below the 1981-2010 February average extent, and tied with 2022 as the 15th lowest on record, according to the NSIDC.
Temperatures are usually “well-below freezing” over the Arctic Ocean in February, but the NSIDC notes that in 2024, they were not as low as usual for the time of year. Over the central Arctic ocean, air temperatures at 2,500 feet above sea level were up to 10C warmer than average.
Labe notes that although sea ice extent was high compared to recent years, the ice is still “much thinner” than it was a few decades ago:
“Total Arctic sea-ice volume ended up as the third lowest on record for the month of February due to the wide coverage of this thinner ice.”

Antarctic ‘behaving strangely’
Meanwhile, at the Earth’s other pole, Antarctic sea ice hit its summer minimum sea ice extent on 20 February. With an extent of 1.99m km2, this year’s minimum ties with 2022 as the second-lowest on record, the NSIDC reports.
The plot below shows Antarctic sea ice extent on 20 February 2024, with the median sea ice extent for 1981-2010 shown by the orange line.
The Antarctic minimum was 850,000km2 smaller than the 1981-to-2010 average summer low of 2.84m km2, but 200,000km2 larger than the previous record low set on 21 February 2023.
This year marks the third consecutive minimum Antarctic sea ice extent below 2m km2. The table below shows the five years with the lowest minimum Antarctic sea ice extent on record, which includes 2022, 2023 and 2024 towards the top.
| Rank | Year | Minimum ice extent (m km2) | Date |
|---|---|---|---|
| 1 | 2023 | 1.79 | 21 Feb |
| 2 | 2022 | 1.98 | 25 Feb |
| 2= | 2024 | 1.99 | 20 Feb |
| 4 | 2017 | 2.11 | 3 March |
| 5 | 2018 | 2.22 | 21 Feb |
“The Antarctic has been behaving strangely,” Dr Mark Serreze, director of the NSIDC, tells Carbon Brief. He continues:
“In the past few years, [southern hemisphere] summer extent has dropped to record lows. Before that, we saw record highs! What has changed?
“The answer seems to lie in the ocean – more warm water getting up the the surface to melt ice or keep it from forming. Is this a temporary effect, or, as many have argued, have we entered a ‘new regime’ in which the ocean will continue to strongly affect the sea ice? Again, we must wait and see.”
Record-breaking Antarctic extent
Antarctic sea ice has been tracking at or near record-low levels for months.
The Antarctic set a record-low maximum on 10 September 2023, with an extent of 16.96m km2. This was “the lowest sea ice maximum in the 1979 to 2023 sea ice record by a wide margin”, and one of the earliest, the NSIDC says.
Antarctic conditions over 2023 were “truly exceptional” and “completely outside the bounds of normality”, one expert told Carbon Brief.
As 2023 progressed, Antarctic sea ice melt was “slower than average”, the NSIDC says. The total decline in Antarctic sea ice extent through October was 903,000km2, while the October average was 985,000km2.
Nevertheless, Antarctic sea ice extent continued to track at a record low. On 31 October 2023, Antarctic sea ice extent was still tracking at a record-low of 15.79m km2. This is 750,000km2 below the previous 31 October record low.
The decline in Antarctic sea ice paused for a few days from 9 November, allowing sea ice extent to creep above the November 2016 value, the NSIDC says. This marked the first time that the daily 2023 Antarctic sea ice extent was not the lowest in the record since early May 2023. By the start of December, Antarctic sea ice extent was again at a record low, it notes.
The Antarctic saw in the new year with a sea ice extent of 6.37m km2, marking the sixth-lowest New Year’s Day Antarctic sea ice extent on record, the NSIDC says. Ice melted rapidly throughout the month, and by the end of January, daily Antarctic sea ice extent reached 2.58m km2 – tying with 2017 for second lowest on record.

Antarctic sea ice ‘behaving strangely’ as Arctic reaches ‘below-average’ winter peak
An exceptional El Niño is building. The World Meteorological Organization (WMO) says it has intensified to very strong levels and is likely to last at least through February 2027. If its current trajectory holds, it could become stronger than anything seen since WMO monitoring began four decades ago.
That is bad news for agriculture. El Niño – a naturally occurring weather phenomenon – can scramble rainfall patterns across the world, bringing drought to some regions and floods to others. And this time it is unfolding against the backdrop of a significantly hotter climate, with farmers already contending with unreliable growing seasons, extreme heat and less predictable rainfall because of global warming.
El Niño expected to bring next record-hot year as soon as 2027
We are seeing the consequences already. In Sri Lanka, drought linked to El Niño has dried wells and reservoirs and cut into crops and farmer incomes. Indonesia is experiencing its worst wildfire season in 11 years, with prolonged drought and extreme heat exacerbated by El Niño. And in Peru, authorities are preparing for the opposite extreme: intense rains, flooding and landslides which the national civil-defence agency says could affect around 1.2 million people.
These impacts will multiply as El Niño intensifies.
And yet, just as the risks to food production are rising, the money available to help farmers withstand them is shrinking.
10% funding decline in 2024
A forthcoming analysis from the Food and Agriculture Organization (FAO) shows that climate-related development finance for agrifood systems is moving in the wrong direction. In 2024, the latest year for which data is available, it fell by 10 percent compared with a 2 percent overall decline. The sectors that put food on our tables — crops, livestock, forestry and fisheries — received just 5 percent.
Yet this is precisely the moment when climate investment in agriculture needs to grow, not shrink. It can help communities adapt, build resilience and protect food security, while unlocking larger flows of public and private finance. Agriculture feeds us, supports the livelihoods of well over a billion people, and is often the first sector hit by drought, floods and extreme heat. Cutting that investment now is a false economy.
One failed harvest can plant the seed for the next crisis, forcing farmers to eat the seed they have saved for planting, sell livestock or tools, or take on debt. It can also deepen food insecurity, disrupt supply chains and drive up prices, showing up months later in supermarket aisles far away.
The Central American Dry Corridor, stretching through much of the region, shows both how exposed farmers are, and what investment can do. Based on an analysis of 41 years of satellite observations, FAO finds that some crop and pasture areas there face more than a 50 percent chance of agricultural drought over the coming months.
About half of Central America’s 1.9 million producers of maize, beans and other basic grains live in the Dry Corridor. Many grow food both for sale and for their own families. When a harvest fails, they lose both income and dinner.
El Salvador project conserves water and soil
In El Salvador, which lies within the Dry Corridor, more than 50,000 farmers have adopted practices to better withstand drought and increasingly unreliable rainfall through RECLIMA, a project financed by the Green Climate Fund and implemented by FAO in partnership with the government of El Salvador. It has substantial national co-financing, including from the country’s Environmental Investment Fund.
El Niño can intensify El Salvador’s annual mid-season dry spell, known as the canícula, turning it into a longer, harsher drought just as maize needs water most.
For María Cristina Corvera de López, a second-generation farmer in rural Nahualapa, adapting means changing how every drop of rain is captured and used. She plants trees alongside her crops to provide shade and minimise evaporation and uses simple irrigation channels and a homemade drip system to conserve water. Instead of burning stalks, leaves and husks after harvest, as generations before her did, she turns them into mulch to hold moisture in the soil.
“The effects of climate change are a constant challenge,” she says. But the new techniques have made her farm more resilient to El Niño as well. Where she once harvested about 50 bags of maize per acre, she now gets around 80, even during droughts. It’s enough to feed her family and sell the surplus.
Managing risk now cuts future costs
Together, these adaptations can mean the difference between losing a crop and getting through a dry season with enough food, seed and income to plant again. They are also the result of climate finance invested before disaster strikes.
RECLIMA shows what that kind of adaptation investment can buy. Adaptation accounted for 45 percent of climate-related development finance to agrifood systems in 2024, and multilateral development banks are directing more agricultural finance towards resilience. That shift reflects a growing recognition that adaptation is a form of risk management, not just a development cost.
We need much more of it. The same investments that help farmers withstand El Niño also enable them to adapt to a hotter, more unpredictable future. Cutting investment in the people who produce our food just as climate risks intensify does not save money. It simply pushes a much larger bill into the next harvest, the next food crisis, and the next El Niño.

An area of Amazon forest roughly the size of the US state of New Jersey has remained standing due to Luiz Inácio Lula da Silva’s leadership of Brazil, according to Carbon Brief analysis.
Lula beat Jair Bolsonaro in the 2022 election to become president of the nation that is home to nearly 60% of the Amazon rainforest.
Forest loss surged during Bolsonaro’s far-right presidency and dropped sharply under the left-wing Lula, with Amazon deforestation likely to hit its lowest level on record this year.
Now, as another presidential election approaches, Lula is facing off against Bolsonaro’s son, Flávio Bolsonaro, whose “anti-environmental” policies are similar to his father’s.
Carbon Brief’s analysis suggests that at least 20,000 square kilometres (km2) of deforestation has been avoided since Lula took office and prioritised Amazon protection.
The analysis is based on modelling by an international research team of an alternative scenario in which Brazil’s flagship forest code legislation was not enforced – a proxy for Jair Bolsonaro’s leadership.
Experts tell Carbon Brief that this estimate is likely “conservative” and that actual deforestation under Bolsonaro could have been “much higher”.
With Lula and Flávio Bolsonaro tied in the polls, the upcoming election is expected to significantly shape the level of environmental action in the world’s fourth-largest emitter, whose emissions are largely driven by deforestation.
‘Brazil is back’
When Jair Bolsonaro was president of Brazil between 2019 and 2022, he championed the nation’s powerful agribusiness sector and oversaw an unprecedented increase in Amazon deforestation.
Bolsonaro weakened regulations, slashed federal agency budgets and empowered illegal activities in the Amazon, while attacking Indigenous and environmental groups.
This meant that the forest code – Brazil’s flagship legislation that requires landowners to preserve and restore forest on their property – was not properly enforced.
After Lula’s presidential victory in 2022, he promised to target “zero deforestation” by 2030, telling the COP27 UN climate summit that “Brazil is back”.
Lula rolled back Bolsonaro’s wave of deregulation and reinstated a deforestation “action plan”. Led by celebrated environmentalist Marina Silva, the environment ministry scaled up enforcement and policing activities in the Amazon.
As a result, annual deforestation in the Amazon has more than halved from 11,594km2 per year in 2022 to 5,731km2 in 2025.
Data from August 2025 to July 2026 – the timespan used in government records – is yet to be released, but preliminary satellite alerts put the deforestation figure at 2,874km2.
While the final figure is likely to be higher, experts still think Amazon deforestation in 2026 could hit its lowest level since records began in 1988.
New Jersey-sized forest
Compared to a scenario in which Bolsonaro won in 2022, Carbon Brief analysis suggests that at least 20,000km2 of Amazon forest remains standing today due to Lula’s leadership.
This area – roughly the size of Wales, Belize, Slovenia or the US state of New Jersey – is indicated by the grey area in the chart below.
This analysis is based on a 2023 study on the role of nature-based solutions in Brazil’s pathway to net-zero emissions. This was a refined update of a 2018 study that used the same GLOBIOM-Brazil model, from researchers at the University of Oxford, the International Institute for Applied Systems Analysis and Brazil’s National Institute for Space Research (INPE).
It is based on a comparison of forest code implementation with a “baseline” scenario in which the code is not enforced, reflecting the kind of weak governance seen under the Bolsonaro administration. (See Carbon Brief’s 2022 article for more details of this modelling.)
Dr Aline Soterroni, a University of Oxford researcher who led the 2023 analysis, tells Carbon Brief that the reversal seen under Lula “shows how quickly deforestation can respond to political will”.
However, she stresses that the modelling of the “no forest code” scenario is “relatively conservative”, with deforestation remaining high but not rising.
Deforestation in this scenario – used here as a proxy for a Bolsonaro election win – is tempered by slower demand growth for Brazilian beef and soy, says Soterroni. She notes that the scenario also does not capture the potential for illegal forest clearing in response to weak governance.
Indeed, some experts anticipated in 2022 that a Bolsonaro victory would send deforestation rates rising to near-record levels.
Claudio Angelo, international policy coordinator at Brazil’s Climate Observatory, tells Carbon Brief that if Bolsonaro had won in 2022, “we have reason to believe [this would have resulted] in much higher rates than during his first term”.
Angelo says the “political signal” would likely have driven an “explosion of wildcat mining” and illegal deforestation in the Amazon. He also points to efforts – including by Flávio Bolsonaro – to formally dismantle the forest code in the Brazilian congress, during Jair Bolsonaro’s first term.
Soterroni notes that deforestation rates did not immediately drop following Lula’s election, as suggested by modelling of a full “forest code compliance” scenario. She says this reflects the “gradual and imperfect process” of restoring and enforcing the law.
Nevertheless, she tells Carbon Brief:
“The key message from our modelling is the contrast between these trajectories: weak environmental governance keeps deforestation substantially higher than full implementation of the forest code. That message remains relevant today.”
Election significance
With Jair Bolsonaro in prison for plotting a coup after losing the 2022 election, his son Flávio Bolsonaro, a senator for Rio de Janeiro, is standing against Lula in the upcoming contest for president.
There are 13 candidates, but Flávio Bolsonaro and Lula are by far the frontrunners and are currently neck-and-neck in opinion polls.
If Lula wins, experts say he is likely to continue with the “zero deforestation by 2030” agenda that has already had a pronounced impact on forest loss.
As the chart below shows, periods when Amazon deforestation fell in recent history all occurred during Lula’s three terms as president.
In contrast, experts say Flávio Bolsonaro, a climate sceptic who has indicated he will continue his father’s political agenda and favour agribusiness and mining, will likely drive a surge in deforestation. Angelo tells Carbon Brief:
“At the risk of sounding alarmist, I’ve been saying that Lula’s re-election is the only thing standing between us and a wide destruction of the Amazon.”
A Bolsonaro win would be a “tremendous disaster”, says Dr Patricia Pinho, deputy science director at the Amazon Environmental Research Institute, adding:
“I don’t think we can afford four years of increasing deforestation [and] violence against Indigenous peoples.”
Dr David Lapola, an ecologist focused on Amazon research at the University of Campinas in Brazil, says he believes deforestation “would certainly rise” and Brazil’s climate and deforestation goals “would be thrown in the trash bin”. He tells Carbon Brief:
“The Bolsonaro administration in the 2019-2022 period showed that the deconstruction of environmental policies and institutes can be done very, very quickly.
“In a matter of a few months, they can destroy what has been constructed over decades of environmental policy and activism in Brazil.”
‘Greenest’ policies
Lula has the “greenest” policy proposals of Brazil’s six top-polling presidential candidates, according to analysis by the Climate Observatory.
The analysis identifies 16 “positive and detailed” environmental commitments in Lula’s proposals, including reaffirming his “zero deforestation by 2030” goal.
Flávio Bolsonaro, on the other hand, has one positive environmental commitment and seven “clearly anti-environmental” proposals.
The right-wing politician has committed to zero “illegal” deforestation by 2029. However, he has also previously led an attempt to change the forest code, opening up large tracts of previously out-of-bounds forest for legal clearance by extractive industries.
Given this, Angelo tells Carbon Brief that he is sceptical about the 2029 pledge.
“The only way you can trust him on this is to think that he is going to revoke the forest code and make all illegal deforestation legal.”
Lula is also the only major candidate to list a clear target for cutting national emissions, sticking with Brazil’s existing goal to cut emissions by 59-67% by 2035, compared to 2005 levels.
Overall, the Climate Observatory notes that climate change and environmental issues “are off the radar for most candidates”, who are instead focusing on the economy and security issues.
Pinho adds that deforestation and the Amazon have not been at the “forefront” of this election, compared to 2022.
If Bolsonaro wins, up to 95% of the Amazon would fall under the leadership of right-wing national governments – including those in Bolivia, Colombia, Ecuador and Peru – reported Mongabay. It noted that presidents in all these nations “explicitly favour agribusiness and mining over environmental conservation”.
If no candidate receives a majority of votes in the first round of Brazil’s election on 4 October, a runoff will take place on 25 October, as has happened at every presidential election since 1998.
Soy moratorium and Brazilian congress
Other factors will also play a role in future deforestation in Brazil, regardless of the next president.
One is the effective end of the Amazon soy moratorium. This is a voluntary agreement signed by companies committing to not buy soya beans grown on land in the Brazilian Amazon that was deforested after 2008.
Conservation organisation WWF’s international director general, Kirsten Schuijt, previously described it as the “most impactful voluntary supply chain policy ever implemented”.
However, major grain traders withdrew from the agreement earlier this year, effectively bringing it to an end. Pinho describes this move as a “huge destruction” of Brazil’s environmental protections.
Research shows the moratorium prevented around 18,000km2 of deforestation in its first decade of operation from 2005-16.
In contrast, a 2026 study estimated that the end of the moratorium could result in 14,000km2 of additional deforestation in the Amazon by 2036.
Alongside choosing a new president on 4 October, Brazilian voters will elect state governors and members of congress, which will also factor into future environmental impacts.
Right-leaning parties, including the far-right Liberal Party linked to the Bolsonaros, currently hold half the seats of the two chambers of congress.
This has led to conflict between lawmakers and Lula. For example, in 2025, congress bypassed Lula’s veto of several aspects of a controversial piece of legislation dubbed the “devastation bill”.
Pinho says that the potential for a right-wing congress and president would be “devastating for the environmental and climate agenda”.
Lapola notes that a Flávio Bolsonaro presidency “would consolidate the view in Brazil that environmental protection is solely a matter of political preference, and not a crucial need of all people”. He adds:
“Land pillage, destruction of precious biodiversity and scorning of Indigenous peoples simply cannot be a nation’s project in the 21st century. We have got to be smarter than that, for sure.”

This letter is a bit more direct and longer than most of those which I write, but I hope you will be okay with that, because the times seem to call for being plain.
A few weeks ago I got a text message from an old and dear friend —let’s call her Hannah.
I have enough shared life with Hannah that, whenever we talk, the conversation always feels current and effortless, despite gaps of months or even years.
Hannah has been talking with her son — we’ll call him Neil — who is a teenager and doing well in school, but wildly worried about the state of the world, including the imminent trajectory of global warming. Hannah and I don’t text each other other very often, but on this occasion she’s reached out with something visceral:
Neil has challenged me to point him to something hopeful, if I can find it. He says so far no one is showing any will to uphold the Paris Agreement. I am checking in to see how you still manage to have real hope.*
Then, just a few days later, the United Nations Environment Programme Limiting Overshoot report landed, containing the principal finding that it is likely the global temperature will soon exceed 1.5°C.
After that news, and the real time devastation in Nepal, and in the context of the broader state of the world, I found myself having multiple conversations with friends and colleagues about the structure of hope. I want to openly share that after a few of these exchanges, I metaphorically closed the blinds, and wondered how to feel, and what to do, because there is no avoiding the dreadfulness of the news, and what it means for the suffering of people and life on Earth.
But if you are fortunate enough to have time, space and security to do so, then after the darkness, you open the shutters and once again there is light. This is the structure of my innermost resolve.
* * *
Our lives — those of us living on our magnificent earth now — have the greatest possible purpose.
There is virtually no problem that we endlessly clever and creative, human beings cannot solve, when we work together.
And we are not just intelligent and ingenious; we are inherently social, nurturing and brave; capable of the deepest enduring love.
Each of the roughly 12,000 generations of humanity so far has made life possible for those who have followed, through acts of devotion.
Babies have been held and fed. Water and food have been found and shared. Shelter has been built. For 12,000 generations we have held the hands of our children.
Every single one of us was once carried in the arms of another, unable to walk ourselves. It is our thoughtfulness, kindness and care that have seen us through as a species. Sometimes this has been in the most exigent of circumstances, when enough of our ancestors did not give in, faced incredibly difficult things, to somehow make it through.
And so it comes to this. To what we now must do. We must do as 12,000 generations of people did for us.
The struggle to keep global warming to under 1.5 degrees may be over. The battle of return—to get our planet back to safe temperatures at emergency speed and scale — is just beginning. Upon this struggle depends the future of all we care about, and that of all life on Earth. The prospects of the next 12,000 generations are conditioned by our efforts now.
Our work now is to keep the overshoot as low as we can, make it as brief as possible, and do everything within our power to alleviate other pressures on nature. It is to take care of humanity — of one another — in the face of mounting climate and ecological damage. And by these efforts, create the conditions for future flourishing. Every fraction of every degree matters.
What must now be done is hard, much tougher than should have been necessary, because of the vested interests in coal, oil and gas and deforestation, and the failures of decision makers. And while renewable energy has surged, making the case for change much simpler, on the other side of the ledger there’s the reactionary and gangsterist turn of politics and the multiplier effects of wars and mass violence, with the existential destabilisation of big tech looming over all.
There is no sugarcoating the scale of difficulty. But what is necessary remains within our collective power. We must never, for one second, say that returning our planet to flourishing is impossible — many of the obvious solutions already exist; but even where transformation relies on reforms, technologies or capabilities that might sound fanciful, or historical changes that are unprecedented, this can be no barrier to our conviction. After all, much of what we take for granted today as ordinary features of social life, would have been considered impossible by every single generation before us.
The world has not been destroyed by nuclear war; we solved the growing hole in the ozone layer; Antarctica was kept sacrosanct from exploitation. Humanity has collectively triumphed before, and can do so again.
We can find the necessary social and political will to do what is needed because these are endlessly renewable resources. The necessary financial capital exists. Apart from the fossil fuel industry, the greatest barrier we face is to mistakenly concede that what lies before us is insurmountable. It is not.
We must avoid the siren song of fatalism. Because. It. Is. Never. Too. Late.
None of which is to be insensitive to the horrors already unleashed — the deadly and grotesque harm to people, places and species that cannot be undone; or to be blind to the impacts that are coming. But where we have the power to act, we also have the responsibility — and the extraordinary privilege — to do what must be done.
Although she is wounded, our planet is still alive and beautiful beyond all of our comprehension. Hundreds of billions of creatures live and thrive still upon this earth. Nothing has happened until it has happened, and life fights for life. Every beetle, every tree, all the fish in the ocean, the smallest of the geothermal shrimps, the greatest of the whales and the mightiest of the birds — all demand life every second of their existence, so that their species too may have future generations.
No individual has to know how to solve this alone. Indeed, finding some detachment and humility is essential to concentrate on the role that each of us can play.
Hope is not merely a mindset or a story we tell ourselves. Collective power is not abstract; it is what we do, together, applying ourselves to the practical mechanics of change and contestation within society, by being part of the organisations and networks of people that are dedicated to effective strategies. It is why I am so committed to Greenpeace.
Working from without and within, there are opportunities to make rapid change within institutions, governments, businesses and communities to create the social, economic and political momentum for emissions reduction at speed and scale, reminding ourselves always of what remains possible, even if it hasn’t happened yet.
We can return the planet to safer temperatures. We can put technologies back in the service of people and life. We can return to the assumptions that seemed so obvious just one generation ago — that it is both possible, and our obligation, to build a better future for all people, and for life on Earth.
I did write back to Hannah and Neil, to say honestly to a treasured friend and her son, that yes, as a matter of faith, conviction, evidence and strategy, absolutely there is real hope. And this is a pledge not just to Neil and his generation, but to the next 12,000.
Together, we have the power. Together, we cross this bridge through the dark. To secure an Earth capable of nurturing life in all of its magnificent diversity.
We did not choose to carry this historic responsibility, but here we are. And it is so lucky that we are here.
I wouldn’t choose any other time to be here, alive on Earth, with you.
