Time is running out [“500-year floods coming annually?” Page One, Aug. 17]. The change caused by global warming seems slow from the standpoint of a single human lifetime, but in fact the predictions of increasing storms, floods, fires and droughts are turning out to be true. We’re losing ice in the Arctic and the Antarctic faster than predicted.

The repercussions in the U.S. are becoming harder to ignore. Louisiana is the latest episode, but it won’t be the last.

Denial is wearing thin. We now know Exxon had, and suppressed, evidence of human-caused climate change for decades. The arguments they paid for are baseless.

Fortunately, the obstruction is crumbling. Some dozen Republicans, including Washington’s own Dave Reichert, R-Auburn, have acknowledged the need to act on climate. And there is an approach that conservatives and liberals can agree on: Tax the things you don’t want, such as CO2 emissions, and return the money to taxpayers in the form of a rebate. Emissions go down, jobs go up, health improves, the economy grows.

We must act now if we want to avert the worst effects of climate change. Let’s start with a sensible win-win, market-driven approach and see what that gets us.
