Earth Day was April 22, and its usual message—take care of our planet—has been given added urgency by the challenges highlighted in the latest IPCC report. This year, Ars is taking a look at the technologies we normally cover, from cars to chipmaking, and finding out how we can boost their sustainability and minimize their climate impact.
The numbers are startling.
We know roughly how much more carbon dioxide we can put into the atmosphere before we exceed our climate goals—limiting warming to 1.5° to 2° C above preindustrial temperatures. From that, we can figure out how much more fossil fuel we can burn before we emit that much carbon dioxide. But when you compare those numbers with our known fossil fuel reserves, things get jaw-dropping.
