Global warming is not linked to CO2: Read the facts here.

Published on 1 January 2020 at 20:26

The climate is changing, this has been happening for hundreds of years and every day. No day is the climate 100% the same. All over the world all kinds of measures are being taken to save the world from an apocalypse. Millions are spent on this every year, but is that money being spent meaningfully?

 

There are still many unanswered questions about the global warming, such as: is there an unmistakable increase in global temperature, does CO2 emissions cause it, are the consequences as alarming as politicians and the media are telling us? And so there are many more fundamental questions. Personally, I think it's important that these questions are answered before any conclusions are drawn and as long as this hasn't happened, I think it's a hypothesis and not a fact.

 

In this column I am going to answer a few questions based on scientific facts or research about global warming and its relation to CO2-concentration. It is up to you to form your own opinion about this.

 

1️⃣ Is the rise in temperature more alarming or more extreme than it should be?
It is a fact that in the last decades of the last century there was a significant warming, but in the last 22 years the temperature on earth has hardly risen at all. Moreover, the climate of the past 150 years is not very different from previous climate changes.

 

Between 1975 and 2005, the average rise in global temperature was fairly high: 0.018°C per year (1.8°C per century). In 1998, the rise in temperature dropped to 0.013°C per year. Now you can say that this is THE proof, but from 1910 to 1945 there was a similar period of rising temperatures of 0.014°C per year. This while the CO2 concentration then was much lower than now. Also in 1945 until 1975 there were two decreases of the average temperature, despite the increasing CO2 concentrations! For me this proves that the increase or decrease of CO2 has nothing to do with global warming.

 

2️⃣ What is the influence of CO2 on climate change?
This question is also the subject of much debate. It has to do with the question whether the recent rise in temperature is the result of human activity or whether there is currently a natural climate change.

 

As I have described in the section above: over the years, during periods of rising average global temperatures, there have been occasional decreases in CO2 concentrations. If there has been a decrease in CO2 concentration, while the temperature has gone up, that means there is no connection between them. If it had been the case that CO2 was the cause of climate change, it would have been that when the CO2 concentration went up so should have the global temperature, but that did not always happen.

 

When shown in a graph, it sometimes seems as if the temperature increased as the CO2 concentration increased. The correlation between this has been scientifically researched extensively on different time scales. It appears that on a timescale of millions of years (not a relatively short period, like is shown in recent graphs) there is no connection at all between CO2 and climate change.

 

In addition, changes in CO2 concentration always follow changes in temperature with some delay. In short: CO2 concentration varies as a result of temperature changes, not the other way around. Do you agree or disagree? Let me know in the comments!
