Re: “Climate change: It’s a natural process” (letter, 4-7).

The writer questioned the wisdom of climate engineering, claiming that climate change is natural and we can do nothing about it.

I agree with the writer on climate engineering, but she gets it wrong on climate change. Natural climate change has occurred for eons, but current global warming is caused by humans.

The science is unassailable: Greenhouse gases warm the atmosphere, human activities have caused recent greenhouse gas increases, the climate is warming and no there is no other credible mechanism to explain the recent warming.

The effects of climate change will largely be harmful, with the greatest harm falling upon the world’s poorest. Suggesting that the world’s poor will be best helped by ignoring climate change is profoundly wrong. We need to focus on proven methods of mitigating climate change such as conservation, energy efficiency and alternative energy.

Ignoring climate change is not an alternative, and neither is reliance on the unproven and risky path of climate engineering.
