Climate Change
The Climate Fixes Already Exist. We're Just Not Using Them Fast Enough.
Most people's mental model of climate change is years out of date, on both ends: the catastrophic scenarios are less likely than the headlines suggest, and the solutions are further along than the doom implies. Solar, wind, and EVs have already won the economic argument. The task left isn't inventing new technology, it's deploying what exists faster than bureaucracy and misinformation currently allow.

The solutions are already cheaper
The evidence
We're Not Doomed, But We're Not Safe Either
If governments do nothing beyond policies already enacted, the world is on track for roughly 2.5 to 3°C of warming by 2100. If every country meets its net-zero pledges, that drops to about 1.8°C. The 1.5°C target is effectively gone, and honesty about that matters, not to give up, but because it changes how fast countries need to adapt. There's no cliff edge at 1.5°C: shaving even a fraction of a degree off the final total still protects real lives. And the feared runaway tipping-point cascade isn't one global switch, it's multiple regional ones, together adding an estimated 0.3 to 0.4°C, unfolding over centuries, not years (Hannah Ritchie, Clearing the Air, 2025).
The World Already Backs Climate Action
A survey of 59,000 people across 63 countries found 86 percent see climate change as a serious threat, and almost two-thirds of Americans back climate action. Red US states generate roughly 70 percent of the country's wind power, and Texas leads the nation in solar. Support for renewables crosses party lines; people just arrive at it for different reasons. Public opinion is not the bottleneck most people assume it is.
Renewables Have Already Won on Cost
Per unit of electricity generated, life-cycle analysis shows solar produces 19 times less carbon than coal, onshore wind 84 times less, and nuclear 180 times less. Solar costs have fallen roughly tenfold since 2010, battery costs are down about 85 percent in a decade, and 96 percent of new solar and wind capacity worldwide is already cheaper than a new coal or gas plant. Intermittency, the standard objection, is a largely solved engineering problem: batteries return about 98 percent of stored energy, pumped hydro is often the cheapest option for week-long gaps, and nuclear and hydropower fill in stable baseload. The real bottleneck is bureaucratic: annual grid investment of about $300 billion needs to roughly double to $600 billion by 2030, and permitting is absurdly slow, one 340-kilometer transmission line in Germany required around 13,500 separate permits.
Electric Cars: Cleaner, Cheaper, and Safer Than Most People Think
More than half of Americans believe EVs are worse for the climate than gas cars. In reality, electric cars produce almost 70 percent less lifetime emissions than gas equivalents in Europe, close to two-thirds less in the US, and 37 to 45 percent less even in China's coal-heavy grid. The manufacturing carbon debt pays back in under two years for the average UK driver, one to three years in the US. Upfront cost is falling fast: BYD sells capable EVs in China from $10,000, and electric models already undercut gas equivalents in the UK used-car market. What people call range anxiety is mostly charger anxiety, an infrastructure gap, not a flaw in the car. And per Norwegian data, gas and diesel cars are roughly nine times more likely to catch fire than electric ones.
Your Plate's Carbon Footprint Beats Your Car's
Food produces between a quarter and a third of global greenhouse gas emissions, driven by staggering inefficiency: only about half the world's cereals reach humans directly, and three-quarters of soybeans go to livestock feed, while all the tofu, tempeh, and soy milk on Earth use just 7 percent of the world's soy. For every 100 calories fed to a cow, three come back as food; pigs return nine, chickens 13. Animal products supply 18 percent of calories and 37 percent of protein, yet grazing and feed crops occupy three-quarters of all agricultural land. Modeling a full shift to plant-based diets shows agricultural land shrinking by 75 percent, not because people eat less, but because so much land currently grows feed instead of food.
Cement and Steel: The Hidden 14 Percent
Cement and steel together account for about 14 percent of global emissions, more than aviation and shipping combined. Cement's problem is chemical: heating limestone releases roughly a tonne of CO2 per tonne of cement produced. Cutting Europe's cement content in concrete from about 78 percent to 50 percent by 2050 would cut the industry's emissions by 40 percent, and near-zero-carbon rock substitutes like basalt exist, at under 1 percent added cost to a typical house. Green steel, made with hydrogen or direct electrification instead of coal, already exists and is being built at commercial scale by companies like Sweden's Stegra. The share of technology needed to fully decarbonize the global economy rose from 50 percent available in 2021 to 64 percent by 2023.
Carbon Removal Is Real, But It's Still a Rounding Error
Most credible net-zero pathways assume the world will need to remove 6 to 10 billion tonnes of CO2 a year by 2050. Today's direct air capture plants remove around 10,000 tonnes a year combined, roughly 0.0003 percent of that target. Cost is the obstacle: about $1,000 per tonne today, against an industry target of $100, the same kind of 90 percent cost curve solar power already proved possible. Solar geoengineering could cool the planet for as little as $2.5 to $18 billion a year, but does nothing for ocean acidification or air pollution and carries unknown risks to rainfall patterns, an emergency option, not a plan. Carbon removal received $1.2 billion in investment in 2023, against $1.8 trillion for clean energy overall; advance-market-commitment programs like Frontier, backed by Stripe, Shopify, and Alphabet, are a template for closing that gap.
What we can do
Phase 1, fix the individual playbook. The actions that actually move the needle are switching your car, your heating system, flying less, and eating less meat, not agonizing over plastic bags and recycling bins. Small virtuous acts that stand in for the bigger changes are moral licensing, not progress.
Phase 2, unblock the grid. Annual grid investment needs to roughly double, from about $300 billion to $600 billion by 2030, to connect renewable projects already waiting in the queue. Permitting reform is just as urgent: no country should need 13,500 permits to build one transmission line.
Phase 3, fund the last mile. Carbon removal needs the same investment trajectory solar got: cost needs to fall from roughly $1,000 to $100 per tonne, and advance-market-commitment programs like Frontier need to multiply well beyond their current $1 billion-plus. Cement and green steel need policy support too, carbon capture incentives, backing for early green-steel plants, and construction rules that allow lower-cement concrete.
