This summer we witnessed, with brutal clarity, the Beginning of the End: the end of Earth as we know it — a world of lush forests, bountiful croplands, livable cities, and survivable coastlines. In its place, we saw the early manifestations of a climate-damaged planet, with scorched forests, parched fields, scalding cities, and storm-wracked coastlines. In a desperate bid to prevent far worse, leaders from around the world will soon gather in Glasgow, Scotland, for a U.N. Climate Summit. You can count on one thing, though: all their plans will fall far short of what’s needed unless backed by the only strategy that can save the planet: a U.S.-China Climate Survival Alliance.

Of course, politicians, scientific groups, and environmental organizations will offer plans of every sort in Glasgow to reduce global carbon emissions and slow the process of planetary incineration. President Biden’s representatives will tout his promise to promote renewable energy and install electric-car-charging stations nationwide, while President Macron of France will offer his own ambitious proposals, as will many other leaders. However, no combination of these, even if carried out, would prove sufficient to prevent global disaster — not as long as China and the U.S. continue to prioritize trade competition and war preparations over planetary survival.

In the end, it’s not complicated. If the planet’s two “great” powers refuse to cooperate in a meaningful way in tackling the climate threat, we’re done for.

That harsh reality was made clear in September. The United Nations then issued a report on the likely impact of pledges already made by the nations that signed the 2015 Paris Climate Agreement (from which President Trump withdrew in 2017 and which the U.S. has only recently rejoined). According to the U.N.’s analysis, even if all 200 signatories were to abide by their pledges — and almost none have — global temperatures are likely to rise by 2.7 degrees Celsius (nearly 5 degrees Fahrenheit) above pre-industrial levels by century’s end. And that, in turn, most scientists agree, is a recipe for catastrophically irreversible changes to the planetary ecosphere, including the kind of sea level rise that will inundate most American coastal cities (and many others around the world) and the sort of heat, fire, and drought that will turn the American West into an uninhabitable wasteland.

Scientists generally agree that, to avert such catastrophic outcomes, global warming must not exceed, at worst, 2 degrees Celsius over pre-industrial levels — and preferably, no more than 1.5 degrees Celsius. Mind you, the planet has already warmed 1 degree Celsius and we’ve only recently seen just how much damage even that amount of added heat can produce. To limit warming to 2 degrees Celsius, by 2030, scientists believe, global carbon dioxide (CO2) emissions would have to be reduced by 25% from 2018 levels; to limit it to 1.5 degrees, by 55%. Yet those emissions — driven by strong economic growth in China, India, and other rapidly industrializing nations — have actually been on an upward trajectory, rising on average by 1.8% per year between 2009 and 2019.
