Preparing humanity for a carbon-neutral future is a daunting task. And based on our progress, we’re not doing a great job.
As the effects of climate change become more impossible to ignore, public understanding of the crisis is rising. Across national borders and political ideologies, a growing number of people accept the fundamentals: We need to make radical changes in our daily habits if we are to have a sustainable future—or, to put it frankly, even a survivable one. In Europe, public support has long been secured for the current E.U. commitments to reducing greenhouse gas emissions to 40 percent of 1990 levels (though there’s also a growing awareness that this will not be sufficient). In the U.S., even as the Trump administration pulls out of the Paris Agreement, the number of people supporting aggressive action to combat climate change has risen to nearly 70 percent.
