IPCC – Back to the Little Ice Age?



11/15/2018 19:20 - Posted by Tom van Leeuwen
Recently, the IPCC published it's “Summary for Policymakers 2018 - An IPCC Special Report on the impacts of global warming of 1.5°C above pre-industrial levels.”

The strange thing is that the IPCC never defines what they mean by “pre-industrial levels”. Do they mean the Holocene Optimum, 8,000 years ago, when temperatures were 4°C warmer than now? That’s a pre-industrial level. Or do they mean the depths of the latest glacial period, 15,000 years ago, with temperatures more than 15°C below the current averages? That’s a pre-industrial level as well.


It’s not until page 6, after repeating “pre-industrial levels” a large number of times, that the phrase is substituted once, and only once, by “the 1850–1900 period”, somehow indicating that is the pre-industrial period they're referring to. After that, it’s back to the very unscientific “pre-industrial levels” wording.
Clearly, the IPCC wants to make sure to frame that the supposed warming has something to do with industrialization.

 
What they do not tell you is that the 1850-1900 period marks the end of the “Little Ice Age”, the coldest period of the Holocene (the last 10,000 years.)
Wikipedia describes that period as “Europeans sought explanations for the famine, disease, and social unrest that they were experiencing”, and “… consequences of the Little Ice Age: livestock epidemics, cows that gave too little milk, late frosts, and unknown diseases.

Is that the type of world the IPCC wants to lead us back to?

The warming we observe is nothing more than the return to the normal situation during the Holocene, leaving behind the extremes of the Little Ice Age.

On a brighter side, the IPCC now forecasts 26-77 cm sea-level rise until 2100 instead of the 26-82 cm they predicted 5 years ago. Maybe they need a couple of additional special meetings at exotic locations in order to discover that the sea level rise is not accelerating at all and that all of the forecasts that were made 30 years ago have failed.

Fighting the climate hysteria is time-consuming! If you think I'm on the right track and you want to support my efforts I would be more than happy to receive a small donation that will help me to maintain this site.

The fingerprints of the greenhouse effect

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.

Why did the warming stop?

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.

Temperature versus CO2 – the big picture

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.

Video - Who are the real climate deniers?

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.

Satellite Earth temperature February 2022

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.

The H2O greenhouse effect

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.

Rob Jetten, Minister of Climate and Energy

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.

Sunspots

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.

As we have seen in recent weeks, new research indicates that there is no increased CO2 emissions. global warming, and that only 12% of the increase in atmospheric CO2 concentration is due to human action.

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.
