"Many are the voices who will say—who have already said, quite vocally—that this is at best nothing more than a stopgap solution. I’m sure our friends from the Maldives, the Laccadives, and the Marshall Islands would take a different view! But of course the detractors have a point. It is absolutely the case that we cannot long survive on a program that consists exclusively of bouncing back the sun’s radiation using a thin veil of gas. We must take advantage of the brief respite that such interventions give us to remove carbon from our atmosphere ." This the big lectern-thumping applause line. "And we must do it," he continued, raising his voice over the clapping, "on a scale that matches—no, even exceeds—the scope of the coal and petroleum industries’ global operations during the last hundred and fifty years. They had a century and a half to put carbon into the atmosphere; we have only decades to take it back out. It will be expensive. But we have money. Abraham Lincoln, in his second inaugural address, said, ‘Yet, if God wills that the Civil War continue until all the wealth piled by the bondsman’s two hundred and fifty years of unrequited toil shall be sunk and until every drop of blood drawn with the lash shall be paid by another drawn with the sword . . . so still it must be said that the judgments of the Lord are true and righteous altogether.’ If, at the end of all this, the pensioners of oil-rich countries are once again only being supported by the proceeds of modern clean industries, then we will truly know that the money has been well looked after."
