The 1.5 degree dream is over

Global warming will soon exceed 1.5 degrees Celsius, the goal set in the 2015 Paris Agreement. The best plausible outcome now peaks near 1.8 degrees, with most projections far worse.

What overshooting really means

Even 1.5 degrees brings severe consequences like extreme storms and fires. Above it, the risk of unmanageable, irreversible damage rises sharply, requiring much larger investments to prepare for inevitable climate disasters.

The failure opens a door

Missing the target clarifies that not all solutions limit warming equally. Nations need to prioritize certain things in certain places right now instead of trying to do everything everywhere at once.

Two problems, not one

The world now faces two separate challenges: limiting how far above 1.5 degrees temperatures peak, and how long they stay there. The solutions that address each are different.

Why the peak matters

Parts of the climate system may fail abruptly beyond certain temperature thresholds. The West Antarctic ice sheet could begin irreversible retreat, Atlantic circulation could slow, or the Amazon could shift from rainforest to something drier.

Duration matters too

A system can survive a brief excursion above its critical threshold but fail under a sustained one. Every additional decade above 1.5 degrees is another decade of pressure on systems that may not recover.

Carbon dioxide is too slow

Replacing fossil fuel infrastructure is vital but carbon dioxide warms slowly for a long time. The net cooling gains from cutting these emissions are real but back-loaded, making it neither sufficient nor most urgent.

Meet the emergency brakes

Reducing super pollutants and stopping deforestation work faster to limit overshoot. These emergency brakes are immediately available with existing technologies and require no complicated infrastructure turnover.

Methane is half a degree

Methane is responsible for roughly half a degree of warming the world has already experienced. Coal, oil, and gas operations leak enormous volumes, but the equipment to stop it is ordinary, available, and often pays for itself.

Other super pollutants are cheap

Nitrous oxide from nylon and fertilizer factories and hydrofluorocarbons from refrigeration are also super pollutants. Both are unusually cheap to eliminate without new technology or infrastructure.

Forests are one-tenth of emissions

Clearing forests releases more than one-tenth of the world's greenhouse gases, roughly the same as the entire United States economy. Brazil, Indonesia, and the Democratic Republic of the Congo account for more than half of global land-use emissions.

Brazil's forest success story

Brazil cut Amazon deforestation by roughly 80 percent across President Luiz Inácio Lula da Silva's first two terms, and sharply again after he returned to office. This is one of the largest climate successes in history.

Indonesia's forest protection

Indonesia cut primary forest loss by nearly two-thirds between 2015 and 2022 under President Joko Widodo, helped by stronger enforcement and a permanent moratorium on clearing primary forest and peatland.

Forests protect people now

Intact natural landscapes buffer against severe storms, droughts, floods, and more. Ending deforestation cuts the risk of catastrophic collapse of these carbon-rich biomes while protecting communities today.

Four new diplomatic moves

Fossil fuel producers can cut methane by requiring low-leak equipment and restricting venting. Importers can insist on these practices to access their markets. Development banks can help poor producer countries.

Pay forests to stand

The international community must create stronger financial incentives for tropical forest countries. Pay-for-performance must make a standing forest more valuable than farmland, building on past partnerships and new mechanisms.

Industrial nitrous oxide cuts

Nations can quickly cut industrial nitrous oxide emissions to eliminate the equivalent of one-quarter of the cars on the road in the United States. Simple standards on a few dozen facilities mainly in China could cut China's emissions by more than 2 percent.

Build resilience for the poor

Wealthy nations must help the poorest withstand inevitable climate-fueled disasters. This requires new capital investments in international financial institutions and regulations to pause debt repayments after mega hurricanes.

Sectoral goals beat global targets

A standing forest has an owner and an export market. Methane mitigation has an industry that profits from selling gas. Sectoral goals are easier to negotiate, implement, and more durable than a single global temperature target.

“A single global number asked the world to do everything everywhere all at once, and delivered too little.”

Benefits beyond climate

Cutting methane means cleaner air in cities where pollution kills people now. Protecting forests means securing water for downstream farms and honoring land rights of indigenous communities. These benefits stand on their own.
