There Never Were Easy Fixes, Now There Are Fewer Fixes Of Any Kind

Anyone who lived in or around New York City in the early 1970s might remember the rallying cry of the city’s upstart baseball team: “Ya Gotta Believe’.’ In more recent times, anyone anywhere might well repeat those words to any climate doubters or deniers. The first step to solving a problem is believing you have one. No pleasure whatsoever, but the following is necessary reading:

It’s Grim

The latest UN report is clear: Climate change is here, it’s a crisis, and it’s caused by fossil fuels.

A new United Nations–led report from hundreds of climate scientists around the world makes it clear: The human-driven climate crisis is now well under way. Earth is likely hotter now than it has been at any moment since the beginning of the last Ice Age, 125,000 years ago, and the world has warmed 1.1 degrees Celsius, or nearly 2 degrees Fahrenheit, since the Industrial Revolution began—an “unprecedented” and “rapid” change with no parallel in the Common Era. What’s more, the recent spate of horrific heat waves, fire-fueling droughts, and flood-inducing storms that have imperiled the inhabited world are not only typical of global warming, but directly caused by it.

Climate change has arrived, in other words, and it will keep getting worse until humanity reduces its greenhouse-gas pollution to zero, which can be accomplished only by dethroning oil, coal, and gas as the central energy sources powering the global economy.

But the speed of that transition matters—and preventing every last ton of carbon pollution, and averting every additional tenth of a degree of warming, will not only lessen the harm over the next few decades, but resound for centuries and even millennia to come.

These are the conclusions of the newest assessment report of the Intergovernmental Panel on Climate Change, a UN-sponsored body that has periodically released a synthesis of current climate science since its founding in 1988. The group’s reports tend to punctuate the otherwise slow immiseration of climate change; its previous synthesis report, released in 2013, helped inform international climate policy, including the writing of the Paris Agreement.

This is its sixth report and its most definitive. The group’s findings must be agreed to by 195 countries; this famously makes it more conservative than some scientists believe is prudent. But compared with previous reports, there is little restraint here. In its strongest statement of culpability ever, the IPCC declared that humanity is “unequivocally” responsible for climate change. “In past reports, we’ve had to make that statement more hesitantly. Now it’s a statement of fact,” Gregory Flato, a vice chair of the group that authored the report and a senior research scientist within the Canadian government, told me…
