Over the last 8,000 years, the atmospheric CO2 concentration has risen steadily, while the average global temperature has declined. This fact contradicts the claim that CO2 is the main "global warming" control knob.
More on the relation between CO2 and temperature: Temperature versus CO2 – the big picture.
CO2 is a greenhouse gas, but it's warming capability is almost saturated. Even at much lower concentrations, it absorbs almost all energy that is emitted in its absorption wavelength bands, so adding more CO2 to the atmosphere has no measurable effect on global temperatures.

The hypothesis of "man-made climate change" tells us that the increase in the concentration of CO2 enhances the greenhouse effect of the atmosphere and has global warming as a final result.
Since the beginning of the industrialized era around 1850, man emits relatively large amounts of CO2 into the atmosphere through the use of fossil fuels. The consequence of these emissions is that during that period, the concentration of CO2 in the atmosphere increased sharply from about 300 parts per million to more than 400 ppm, an increase of almost 40%. The average temperature increased in the same period more or less 1.5 °C with a small variation depending on the data source used. Read more...
The political reports of the IPCC are based on the hypothesis that CO2 is the most important control knob of the Earth's temperature. The problem is that this hypothesis does not correspond at all with the empirical data available to science. Forecasts are made using models that are not capable of 'predicting' the past.

When discussing “Climate Change” it’s good to have an understanding of how the Earth’s climate has changed in the past. That will give us a reference to decide whether the current changes are normal or not.
Global temperatures have varied a lot over the last 500 million years. Depending on the timescale used, the current temperature is either cold or hot, so when you want to know the “normal temperature” you’ll have to indicate what timescale you’re using. Read more...
The climate has shown many fluctuations during the Holocene. The difference between the highest and lowest average temperature of the past 10 thousand years is about 3 °C.
Climate alarmists, led by the IPCC, are trying to deny this, and understandably so. This variation means that without human influence there was climate change as well.
This undermines their hypotheses and often their jobs depend on it.

The satellite temperature departure measurement for February 2022 is exactly 0° C.
This means that Earth temperature during February 2022 was exactly the same as the average from 1991 to 2020.
Satellites are the best way to have insight into the short-term temperature variations. They measure the whole surface, independent of weather station distribution, Heat Islands, measurement failures, surface condition (land or water).
There is a step-wise increase in temperature, triggered by two very strong El Niño events (1998 and 2016.) The energy that welled up from the deep oceans established a new level in these two ocasions, where the warming paused. This is a natural phenomenon and has nothing to do with CO2, or human activity.
Where is the Climate Emergency? It just does not exist.
Wake up and spread this information to your government!
The IPCC's CO2 hypothesis, with which Western governments try to incite their citizens to group-think, panic and unnecessary measures and taxes, rests in large part on the belief that there is a positive feedback effect between the greenhouse effects of CO2 and water vapor (H2O). A small increase in temperature, caused by the increase in CO2 concentration, would lead to an increase in water vapor concentration and thus increase the H2O greenhouse effect.
This is a misconception. First, positive feedback effects are extremely rare in nature. Furthermore, there is no sensible word to say about the effect that an increase in the H2O greenhouse effect has on the temperature.
Below are three reasons why it is impossible to model this effect. Read more...
Rob Jetten is the new, brand new Minister of Climate and Energy in the Dutch cabinet Rutte IV.
This is a new ministry, but unfortunately it is characterized by the same ideas as in previous cabinets. The idea that humans, by burning fossil fuels, are responsible for the recent warming of the Earth. Read more...
This article is partly based on the thorough research done by Freek van Leeuwen on the scientists Valentina Zharkova and Willie Soon and their work on sunspots.
Good news, then, but then the question arises where the heating comes from, which many people feel and which can also be seen in the monthly charts of the satellite measurements. Read more...
