“Even if the United States deals with its carbon emission problem, the Chinese won’t. So what’s the point?”
“You can’t condemn the entire global South to abandon energy development, and you can’t provide enough with solar and wind. So what’s the point?”
“Besides, the whole enterprise of trying to achieve a future sufficiently carbon-free to deal with the most important problems is politically hopeless.”
These challenges are sometimes spoken, sometimes not, but they commonly and powerfully weaken efforts to deal with the climate crisis. Despite the well-funded bluster of disingenuous or, at best, delusional skeptics and deniers, a majority of Americans believe the climate is changing in worrying ways, and many (PDF) also believe that these changes pose a threat to current and future generations. But this belief has not yet translated into action at a scale adequate to the problem we face.
