Warming? It’s beyond man

Sir, – With all the climate-related material in the media just now it’s obvious that the next international climate junket is imminent.

But let’s remember that the man-made global warming theory has never been proven.

Indeed many scientists think that there has been no significant warming.

In 1972 scientist John Sawyer published a paper suggesting that an increase in atmospheric CO2 due to human activity would lead to an increase in global temperatures.

In 2003 Nir Shaviv published a scientific study suggesting that 66% of climate variation could be attributed to cosmic ray flux.

He states that “there is no substantial evidence which proves that CO2 and other greenhouse gases are the primary cause for the warming”.

In 2017 scientists Nikolov and Zeller published a paper suggesting that equilibrium temperatures are dependent on two variables: top of atmosphere solar irradiance and surface atmospheric pressure. They state that the greenhouse effect has been misrepresented to the public and is “independent of atmospheric composition”.

In other words, it doesn’t matter how much CO2 there is. I could go on.

It is absurd that government policy is based on just one theory.
