As always, the word is that we can do it if we really get serious and hurry up, and the obvious problem is that we’re not going to.
The report by the Intergovernmental Panel on Climate Change, a body of experts convened by the United Nations, warns that unless countries drastically accelerate efforts over the next few years to slash their emissions from coal, oil and natural gas, the goal of limiting global warming to 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, will likely be out of reach by the end of this decade.
That’s the threshold beyond which scientists say the dangers of global warming — including worsening floods, droughts, wildfires and ecosystem collapse — grow considerably.
And what goes along with worsening floods, droughts, wildfires and ecosystem collapse? Mass migrations, and resistance to mass migrations, and wars and genocides. In a world that’s already broken. It will be horrible. It will be Mariupol everywhere and Treblinka everywhere.
But the task is daunting: Holding warming to just 1.5 degrees Celsius would require nations to collectively reduce their planet-warming emissions roughly 43 percent by 2030 and to stop adding carbon dioxide to the atmosphere altogether by the early 2050s, the report found.
Yeah. Do we look as if we’re doing that? Do we look as if we’re going to be doing that starting today?
By contrast, current policies by governments are only expected to reduce global emissions by a few percentage points this decade. Last year, fossil fuel emissions worldwide rebounded to near-record highs after a brief dip as a result of the coronavirus pandemic.
Governments probably can’t do anything about it without being overthrown and replaced by governments that will undo any doing.
The report, which was approved by 195 governments and lays out strategies that countries could pursue to halt global warming, comes as Russia’s invasion of Ukraine has caused oil and gas prices to skyrocket, diverting political attention from climate change. In the United States and Europe, leaders are focused on shoring up domestic fossil fuel supplies to avoid painful price spikes and energy shortages, even if that means increasing emissions in the short term.
But of course there is no “short term.” There’s no short term in the sense that “we can keep on with the fossil fuels for just this one short term and then we’ll immediately slash them by 43 percent and the planet will be saved.” How long would that short term be exactly? How would we know? What would be different such that an immediate switch to using roughly half of what we’ve been using would be quick and painless? Don’t make us laugh. It’s not possible. Animals don’t evolve to take the long view, not even as long as the next eight years. When heating costs double from one month to the next it’s game over.
But even if that goal becomes unattainable, scientists said, it will still be worthwhile for countries to slash emissions as quickly as possible to prevent as much warming as they can. Every additional rise in global temperatures increases the perils that people face around the world, such as water scarcity, malnutrition and life-threatening heat waves, the U.N. panel has found.
And what goes with them: mass migrations, wars, genocides. I think the panels and journalists should include that part, even though it’s not as trackable as water scarcity and the rest.
