Bill Gates Says Climate Won’t End Humanity and Urges UN to ‘Pivot’ to Poverty, Disease

In a post on his Gates Notes platform, titled “Three tough truths about climate (A new way to look at the problem)”, Bill Gates says climate change is a serious global problem, but not the biggest immediate threat to human life. He argues that the world should stop treating global warming as an unstoppable apocalypse and instead spend the scarce resources on cutting poverty, tackling infectious disease, and helping vulnerable countries adapt.

Just like I already did in the article “Why “Doom Thinking” in the Climate Debate Definitely Doesn’t Work“, Bill Gates now also calls the “doomsday view of climate change” – as propagated by Greta Thunberg for instance – completely wrong.

The 17-page memo by Bill Gates is published ahead of next month’s UN climate summit (COP30) in Belém, Brazil. Bill Gates writes: “Although climate change will have serious consequences – particularly for people in the poorest countries – it will not lead to humanity’s demise. People will be able to live and thrive in most places on Earth for the foreseeable future.”

Bill Gates says the climate community has focused “too much on near-term emissions goals,” driven by an almost end-of-the-world narrative. He wants a “strategic pivot” in which “improving lives” becomes the main metric, and not just measuring temperature and CO₂ levels.

Gates touches a few interesting points in his memo, which reads more as an essay.

What Bill Gates wants to prioritize now

Bill Gates states that, for most people in low-income countries, the biggest daily threats are malaria, hunger, and extreme poverty and not the 0.1°C change in global average temperature over the next few years. He told reporters that, given a choice, he would “let the temperature go up 0.1 degree to get rid of malaria,” arguing that hundreds of thousands of people are already dying from preventable diseases today.

He adds: “The biggest problems are poverty and disease, just as they always have been.” He says that climate policy should be judged on how well it reduces real suffering for those people, and not just how fast it cuts carbon.

Bill Gates however also adds that this is not a call to abandon climate action. Gates says climate change “is a very important problem” and that “every tenth of a degree of heating that we prevent is hugely beneficial.” But he argues that the money on the table is limited. So spend it where it saves the most lives per euro, per dollar, per intervention.

It’s quite a turn in tone from the message Bill Gates pushed in 2021 with his book “How to Avoid a Climate Disaster,” where he warned that avoiding catastrophic warming required getting to net-zero greenhouse gas emissions. He still backs decarbonisation and says he has invested billions in clean-tech innovation, including Breakthrough Energy (founded in 2015) to scale nuclear, geothermal, low-carbon fuels, and other zero-carbon solutions.

Now, though, he says focusing only on temperature targets distorts these priorities. He claims that a narrow obsession with cutting emissions today can block poorer countries from building infrastructure, powering hospitals, or running fertilizer production – all of which keep people alive. He argues that some anti-fossil-fuel pressure on the Global South hurts health and food security without materially changing global emissions, because most pollution still comes from rich and emerging industrial economies.

He also pushes adaptation and points to solutions like reliable electricity, air conditioning in heat-prone regions, climate-resilient agriculture, and disease control as urgent life-savers.

Bill Gates (born 1955, Seattle) co-founded Microsoft with Paul Allen in 1975 and led the company as CEO until 2000. He chaired the board until 2014 and left Microsoft’s board in 2020 to focus on philanthropy. Gates studied at Harvard before leaving to build Microsoft, which became the dominant PC software company through MS-DOS and Windows. He co-founded the Bill & Melinda Gates Foundation in 2000, funding global health, vaccines, education, and poverty-reduction programs. He also founded Breakthrough Energy to accelerate climate-tech innovation and wrote “The Road Ahead,” “Business @ the Speed of Thought,” and “How to Avoid a Climate Disaster.”

In the below table I’ll show you how adaptation interventions can avert deaths. In this case it’s about heat early-warning systems (EWS) and the causality with direct mortality reduction. All figures come from World Bank analyses.

City & package	Cost used	Avoided heat-related deaths	Deaths averted per €100k
Surat – EWS (low ambition)	$0.314M	304	96.8
Surat – EWS (high ambition)	$0.314M	608	193.6
Chennai – EWS (low ambition)	$0.320M	713	222.8
Chennai – EWS (high ambition)	$0.320M	1,426	445.6
Lucknow – EWS (low ambition)	$0.353M	311	88.1
Lucknow – EWS (high ambition)	$0.353M	623	176.5

Other World Bank data also revealed what urban tree-canopy programs offer: cooler microclimates, and fewer heat deaths.

City & ambition	Total program cost	Heat-related deaths avoided (range across scenarios)	Deaths averted per €100k
Surat – trees +10%	$2.2M	272–365	12.4–16.6
Surat – trees +30%	$6.6M	816–1,095	12.4–16.6
Chennai – trees +10%	$7.4M	580–914	7.8–12.4
Chennai – trees +30%	$22.1M	1,740–2,741	7.9–12.4
Lucknow – trees +10%	$3.9M	269–418	6.9–10.7
Lucknow – trees +30%	$11.8M	806–1,253	6.8–10.6

Why this lands in a very heated moment

Bill Gates published his memo one day after the United Nations publicly said the world has already missed the target of keeping warming below 1.5°C and warned of “devastating consequences.” UN Secretary-General António Guterres said humanity will overshoot 1.5°C “in the next few years,” and called for an immediate course correction to avoid irreversible tipping points in the Amazon, Greenland, western Antarctica, and coral reef systems.

Guterres said leaders must accept that “we have failed to avoid an overshooting above 1.5C,” and warned that delaying deep emission cuts now raises the risk of collapsing rainforest ecosystems and accelerating polar ice loss. He described those shifts as a direct threat to food security, clean water, and political stability.

In other words: the UN is telling governments to slash fossil fuel use fast to prevent runaway damage. Bill Gates is telling them to judge success by human welfare first, even if warming ends up at 2–3°C by the end of the century.

What the science says about “2–3°C”

The Intergovernmental Panel on Climate Change (IPCC) finds that, under policies currently in place, global warming is on track for roughly 2.5–3°C by 2100 unless countries strengthen action. The IPCC’s Sixth Assessment Synthesis Report (2023) states that without stronger policies, warming of about 3.2°C [2.2–3.5°C range] by 2100 is projected. Independent modeling groups such as Climate Action Tracker estimate around 2.7°C under current policies.

At 2–3°C of warming, scientists project far more deadly heatwaves, crop failures in tropical regions, stronger floods and droughts, and faster sea-level rise. The World Meteorological Organization and the World Health Organization already link more frequent wildfires, extreme heat, and dangerous air pollution to climate change, and warn that these stressors are killing people and disrupting economies.

A new Lancet Countdown report prepared with contributions from WHO and major research institutions estimates that extreme heat now causes about one death every minute worldwide, averaging roughly 546,000 heat-related deaths per year from 2012 to 2021. The same analysis reports a 23% rise in heat-related mortality compared to the 1990s, plus 639 billion hours of labor lost in 2024 because workers could not safely perform outdoor jobs in extreme heat.

WHO and global health agencies say climate change already undermines clean air, safe drinking water, food systems, and shelter, and warn that “climate inaction is claiming millions of lives every year.” They describe climate change as a major threat to global health and call for adaptation money and fossil fuel phase-down at the same time.

So although Bill Gates dismisses “humanity’s demise” scenarios – he calls the extinction framing wrong – mainstream science still links rising temperatures directly to avoidable death, displacement, and instability, especially in low-income and equatorial regions.

The moral argument: who suffers first

As I pointed out, Bill Gates does not deny that climate damages fall hardest on people who did the least to cause them. He stresses that farmers in sub-Saharan Africa and South Asia face harsher droughts and floods, and that hotter nights, failed harvests, and shifting disease patterns will keep pushing families toward hunger and forced migration. He calls this “deeply unfair” in his post and uses that point to argue for more investment in climate-resilient agriculture, vaccines, and malaria control.

Bill Gates’ point of view is broadly consistent with public health data. WHO notes that climate-driven heat, food insecurity, and infectious disease are already reversing decades of progress in global health and poverty reduction. The UN warns that the poorest communities, including Indigenous populations and small island nations, are already absorbing the first wave of damage: flooded villages, saltwater intrusion, wildfire smoke, coral collapse, and loss of arable land.

Where Bill Gates diverges is in what to do first. He wants more direct spending on malaria eradication, child vaccination, and agricultural resilience now, and a long-term bet on energy innovation to drive emissions down later. He says rich countries are already cutting foreign aid budgets, so every available dollar needs to deliver maximum welfare per person, per year.

Here’s a compact table that compares lives saved per €100,000 across high-impact health interventions and a climate-mitigation benchmark.

Intervention	Setting / Notes	Cost per death averted (USD)	Deaths averted per €100k (≈)	Primary source(s)
Measles vaccination	Ethiopia ECEA across public-financed options	—	367 per $100k	Lancet Global Health
Pneumococcal conjugate vaccination	Ethiopia ECEA	—	170 per $100k	Lancet Global Health
Insecticide-treated bed nets (ITNs)	Sub-Saharan Africa; long-lasting nets	$556–$635	180–157 per $100k	Resource Allocation in Health
Seasonal Malaria Chemoprevention (SMC)	Sahel, 7 countries (programme scale)	$534–$2,257	188–44 per $100k	Lancet Global Health
CO₂ abatement (generic mitigation)	Convert “mortality cost of carbon” to lives saved via abatement at two price points	—	0.45 per $100k @ $50/tCO₂; 0.23 per $100k @ $100/tCO₂	Nature Communications

Important when reading this table: Health interventions (measles, pneumococcal, ITNs, SMC) directly avert deaths now and therefore score extremely high on a “lives per euro” basis in the cited contexts. The climate line uses a peer-reviewed mortality metric and standard abatement cost ranges; it captures only temperature-related mortality, not broader climate damages or co-benefits (e.g., cleaner air from coal phase-out). It is therefore a conservative, partial comparison for climate action.

Bill Gates is not the only one who has shifted his view

There are several well-documented examples of prominent figures who have shifted toward the Bill Gates-like line (“climate is serious but not an apocalypse; focus on human welfare, adaptation, and pragmatic tech”).

1. James Lovelock (Gaia theory)
   Lovelock warned in 2006 that “billions” could die this century from warming. But he admitted in 2012 that he had been “alarmist,” saying warming hadn’t accelerated as he’d projected; and urged a more pragmatic stance (incl. gas and nuclear).
2. David Wallace-Wells (author of “The Uninhabitable Earth”)
   In 2017/2019 he wrote about emphasized worst-case pathways (5°C-style futures). But by 2022 he stated that policy and market shifts have made the worst-case “considerably less likely,” and argued for a less apocalyptic, more solutions-oriented frame.
3. George Monbiot (Guardian columnist)
   Monbiot was a long-time critic of nuclear power. But after Fukushima (2011) he switched to pro-nuclear as a practical climate tool which represented an explicit pivot from purist positions to solution pragmatism aligned with Bill Gates’ focus on tech that protects lives.
4. Mark Lynas (author of “Six Degrees”)
   Known for stark climate-risk warnings, Lynas was also previously anti-nuclear. He became strongly pro-nuclear in 2012 (“Without nuclear, the battle against global warming is as good as lost”), and in 2025 argued that nuclear war now ranks as a bigger immediate existential risk than climate – downgrading the “end-of-civilization” climate narrative.
5. Steven E. Koonin (Obama-era U.S. DOE science official; NYU)
   Koonin served within an administration that framed climate as a top global threat. In “Unsettled” (2021) however he argues the dominant crisis narrative overstates what mainstream reports support and urges policy grounded in measured risk and adaptation, which is closer to Bill Gates’ “don’t do doom; do welfare-maximizing action.”
6. Michael Shellenberger (environmentalist, Breakthrough co-founder)
   Shellenberger was a high-profile renewables advocate, hailed by Time in 2008; and spoke in classic “climate emergency” terms. But in “Apocalypse Never” (2020) he argues that alarmism hurts the poor and distracts from pragmatic solutions (incl. nuclear and adaptation).

And there are many more former doomsday activist that have seen the pragmatic light.

The pushback from climate scientists

Some climate scientists say Bill Gates risks creating a false choice. Princeton climate scientist Michael Oppenheimer agreed that human well-being must be the “primary objective,” but warned that nature is already “wreaking havoc,” and asked whether humanity can really live in a sealed technological bubble while ecosystems crash.

As I said already UN Secretary-General António Guterres from his side says that overshooting 1.5°C “has devastating consequences,” including tipping points such as a dying Amazon rainforest that could flip to savannah. He warns that a world that keeps burning fossil fuels will become a “free-for-all” where a “small privileged elite” can still buy safety while everyone else deals with floods, famine, and forced migration.

It really is an underlying tension. Bill Gates prioritizes immediate poverty and disease reduction, arguing that people can “live and thrive in most places on Earth for the foreseeable future.” UN leadership and much of the climate science community warn that letting warming run past agreed limits risks structural damage to food systems, freshwater, and regional stability, which then drives poverty and disease.

Why you should care before COP30

COP30 will convene heads of state and ministers in Belém, Brazil, in November. Bill Gates calls that meeting “a chance to refocus” on health, poverty, and adaptation for the world’s poorest. He asks to not just focus on pledges to cut CO₂.

The UN, meanwhile, is pressing those same leaders to admit that humanity already blew past the Paris pathway, to slash fossil fuel use fast, and to stop pushing climate costs onto vulnerable countries that did not create the crisis.

Both positions accept that climate change is real, driven by greenhouse gas emissions, and already dangerous. Both say rich countries must spend more money. The fight now is about sequencing.

• Bill Gates: Save lives today (malaria, food, cooling, infrastructure) and bet on innovation to clean up energy over time.
• The UN and climate scientists: Slam emissions down now to avoid tipping points and runaway damage that will erase those same lives tomorrow.

That argument will define COP30.
