Put trust in the climate experts

Sir, – Your correspondent Angela Rennie is incredulous that humans can change the world’s climate (Letters, December 8). Why?

She is an enthusiastic recycler.

By her logic, should we not just dig up virgin material, make plastic, use it once, then dump it in the oceans?

I have been to the Pacific – it’s really, really big.

Atmospheric carbon dioxide is at its highest concentration for three million years.

That came mostly from our burning of fossil fuels.

We have measured both of those things.

We have changed the entire global atmosphere.

That is simply fact. It was in 1988 that the Intergovernmental Panel on Climate Change (IPCC) was established.

Since then we have not, as she suggests, subtly switched to the term climate change.

The clue was in the name.

Acid rain, and the hole in the ozone layer, didn’t just go away on their own.

There were international treaties on reducing the emissions causing such damage.

Your correspondent may have heard of the global Montreal Protocol on Substances that Deplete the Ozone Layer.

The hole in the ozone layer over Antarctica is still there, but it is slowly recovering.

All of your letter writer’s talking points can be found on American “wing-nut” websites.

Why should we believe them, and not climate scientists?
