The very heart of climate alarmism is the claim that CO2 levels control the temperature of the earth. So let us examine that by simply looking at the history of the earth.
Ice core data has provided a very good record of the earth’s historic temperature as well as its CO2 level. Here it is:-

Now when you compress hundreds of thousands of years into a graph a few inches wide a relationship between CO2 and temperatures is clear for all to see. So there is no doubt that there is a relationship …… except that it is the exact opposite of what the alarmists claim.
What the graph shows is that the temperature changes ﬁrst and then on average about 800 years later the CO2 increases. Hence the temperature change causes the CO2 change and not as the alarmist claim the other way around. In fact that has always been the case throughout earth’s history.
In real science it is not enough to show such correlations. After all ice cream sales correlate well with temperature but do not cause it. You have to show a cause and effect that makes sense. So what would cause CO2 rise to follow temperature rise?
The answer is very simple.
By far the most free CO2 on earth is stored in the oceans, and they absorb CO2 when cooling, and conversely give off CO2 when warming. So as the temperature increases, then the oceans begin to slowly give off CO2.
Boiling a kettle of water takes time, so imagine how much time it takes to heat up blue planet oceans such as those on earth? The answer is hundreds of years. So it is clear what is happening – temperature increases and then as a result, CO2 levels in the atmosphere increase. Hence CO2 cannot be the cause of the temperature increase, but are a RESULT of it.
Of course this is simply ignored by the alarmists. They even claim that current CO2 levels are the highest we have ever had when the fact is they are at drought levels. The alarmists trade in the exact opposite of the truth and so have to suppress the truth and even turn it on its head. To do that they have to abandon the scientiﬁc method and squash free speech. So far they have done that very well indeed because today 2+2 does equal 5.
You only have to ask the BBC that.
