Net Zero Activists Stumped By Shock New Evidence Showing No Link Between CO2 & Temperature Over Last Three Million Years

The climate science world (‘settled’ division) is in shock following the discovery in ancient ice cores that levels of carbon dioxide remained stable as the world plunged into an ice age around 2.7 million years ago.

Massive decreases in temperature with occasional interglacial rises appear to have occurred without troubling ‘greenhouse’ gas levels, and this revelation has caused near panic in activist circles.

Levels of CO2 at around 250 parts per million (ppm) were said to be lower than often assumed with just a 20 ppm movement recorded for the following near three million-year period. In addition, no changes in methane levels were seen in the entire period.

The assumed level three million years ago of CO2 was around 400 ppm, a convenient mark that has been used to explain the subsequent ice age and a drop to 250 ppm. Due to the recently published paper, this explanation has become more problematic and natural climate variation is correctly noted to have occurred with the temperature changes.

Alas, similar explanations are mostly ignored in discussing today’s climate changes in the interests of promoting the Net Zero fantasy. Some cling desperately to a dominant CO2 role.

In short, there is a great deal of applying the laws of physics and chemistry to one era, but failing to extend the same courtesy to another.
 
Can you explain how it makes sense? Like, can you actually form a cohesive opinion on the matter?
Hold on Flea, I’m going to learn you something.

As we know, the climate alarmists boogeyman is CO2 in the atmosphere (even though it’s in tiny quantities there and water vapour has many times the greenhouse effect). And those climate alarmists have told us that atmospheric CO2 is what controls climate warming and cooling over time.

But what do we have here with these ancient ice cores that scientists drilled in Antarctica? We have PROOF that massive climate swings took place in the past 3 million years DESPITE CO2 levels in the atmosphere remaining stable.

Cooling was NOT precipitated by reduced CO2 in the atmosphere and warming was NOT produced by increased CO2 as had been predicted by climate alarmist models.

CO2 had NO LARGE EFFECT on the climate for 3 million years.

What else would you like to know?

I dont think you quite understand what you are reading


Just because you can have climate shifts without a change in co2, does not mean that a rapid change in co2 levels can not cause climate shift
