We face an existential threat. Life as we know it is on the line.

We have 12 short years to change everything, or it's game over.

This is the terrifying scenario that's used by many leading politicians to justify a green new deal.

An unprecedented increase in government power focused on the energy industry.

The core idea of a green new deal is that government should rapidly prohibit the use of fossil fuel energy and impose 100% renewable energy, mostly solar wind.

This may sound appealing, but consider what it would entail.

Today, 80% of the energy Americans use to heat their homes, farm their land, run their factories and drive their cars comes from fossil fuels, coal, oil, and natural gas.

Only 3.4% comes from solar and wind, despite decades of government subsidies and mandates to encourage their use.

The reason we don't use much sunlight and wind as energy is that they are unreliable fuels that only work when the sun shines and the wind blows.

That's why no town, city, or country has ever come close to 100% or even 50% solar and wind.

And yet, green new deal proponents say they can do the impossible.

If only we give the government control of the energy industry and control of major users of energy, such as the transportation industry, manufacturing, and agriculture.

All of this is justified by the need to do something about the existential threat of rising CO2 levels.

We're told on a daily basis that prestigious organizations like the United Nations have predicted mass destruction and death if we don't get off fossil fuels.

What we're not told is that such predictions have a decades-long track record of getting it wrong.

And by wrong, I mean completely missing the dartboard wrong.

For example, in 1989, the Associated Press reported a United Nations prediction that entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend is not reversed by the year 2000.

We're now two decades past 2000. We're not missing any nations and human beings are living longer, healthier, and wealthier lives than ever before.

But aren't things bound to get worse? Haven't scientists established that CO2 is a greenhouse gas with a warming influence on the planet? Yes, but that's only a small part of the big picture.

Although CO2 causes some warming, it's much less significant than we've been told.

When we started using significant amounts of fossil fuels in the middle of the 19th century, we've increased the percentage of CO2 in the atmosphere from 0.03% to 0.04%, which correlates with an average temperature increase of about 2 degrees Fahrenheit.

It also correlates with significant global greening, because CO2 is plant food.
