Will climate change action be too late?

Your editorial on climate change is welcome (March 31), but I wonder is it all simply too late?

We have taken billions of tonnes of trapped carbon from under the earth and pumped it into the atmosphere with devastating effect.

Even if we stopped the practice dead in its tracks, scientists say it’s likely we would feel the consequences for generations. To stop the destruction we would have to go against the most pernicious human trait of all – greed.
