We’re not reaching the UN’s Global Goals. What now?

There’s a lot of focus now on the politics of Paris. Will poor countries get the "climate aid" they want? Will China agree to reduce its growth, leaving millions more in poverty, by committing to far-reaching carbon cuts? What will be the wording of the treaty that emerges?

It’s easy to become cynical. Let’s instead take a step back and ask a much more interesting question: what would it take for Paris to succeed? By this, I don’t mean that the delegates manage to sign some kind of treaty. I mean, what would it take for Paris to have a real impact on climate change?

Trying to showcase climate leadership at the U.N. Climate Summit in Glasgow, President Joe Biden is reaffirming his goal of creating “a carbon pollution-free power sector by 2035 and net-zero emissions economy by no later than 2050.” But that target will be prohibitively expensive. A new Nature study shows that a 95 percent reduction by 2050 — almost within reach of Biden’s net-zero — would cost 11.9 percent of GDP or more than $11,000 for each American every year.

The online world has become a free-speech battleground. Tech platforms have sided with illiberal regimes to censor posts while flagging “misinformation” in free countries. We all share a legitimate interest in avoiding outright falsehoods, but much censorship today — whether at dictators’ behest or in the name of eradicating “misinformation” — ultimately is about restricting discourse to a narrow corridor of the politically acceptable. That makes it harder to identify smart policies.
