Emotion versus Science

09/25/2019 12:05 - Posted by Tom van Leeuwen

There are not more hurricanes than before. There are not more tornadoes than before. There are not more forest fires than before. There are not more heatwaves than before and the heatwaves do not last longer than before. The sea-level rise does not accelerate. We enjoy a slight increase in temperature, but it is not hotter than at other times of the Holocene.

The IPCC models do not work; the warming is much lower than predicted.

As they have understood that all the facts are against them, the UN has changed its strategy. They now play the "emotion" card. Theater time has arrived.

At the UN climate summit in New York, it was not about science, they have not proved the CO₂ hypothesis, they have not even touched on the subject. It was all about commitments and promises, appearing to be the most worried, the most committed to the cause.

A couple of blocks away from the UN headquarters, The Heartland Institute had organized a climate change conference. They invited more than twenty politicians, scientists, and journalists to share their views on the climate and to discuss science, including Michael Mann and Alexandria Ocasio Cortéz. The proposal was to discuss the issue with three realistic scientists, experts in astrophysics and climate.
Of the twenty invited guests, not one appeared. Many of them never responded to the invitation, others had some kind of excuse despite receiving the invitation well in advance. They simply do not dare to discuss the science behind their hypothesis with experts because they know they are without arguments and will lose the discussion.

So we have seen a lot of emotion, a lot of theater in New York, but unfortunately, very little science.

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.

Thanks!

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.

Dutch Warming

In the Netherlands, the day-to-day whether depends heavily on the direction the wind is coming from. Being a small country, the wind direction is quite homogeneous for the whole country, specially on higher altitudes where the bulk of heat convection is taking place.

Due to its geographical position, midway between the icy-cold Arctic to the north, the dry and hot Sahara to the south, the Eurasian land-mass to the east and the Atlantic Ocean to the west, every wind direction comes with unique weather characteristics.

North - cold,
East - dry,
South - warm,
West - wet whether.

Satellite temperature observations

This month of January 2023, the average satellite temperature published, by Dr. Christy and Dr. Spencer (University Alabama Huntsfield) had a negative deviation, compared with the average monthly measures between 1991 and 2000.

Of course, this value does not mean much, it's definition is full of arbitrary begin and endpoints, but anyway it doesn't sound like a lot of warming has taken place over the past 30 years, and even less "catastrophic warming" we're reading about in the Mainstream Media, newspapers and TV stations.

CO₂ saturation

This graph is all you need to understand that CO₂ is not the Earth's Climate Control Knob.

On the horizontal axis, we see the Infra-red (IR) spectrum wavelengths, that is like "IR colors" were this kind of radiation visible to the human eye.
The vertical axis shows to energy flux, that is the energy emitted by the Earth, as seen from outer space.

The graph itself shows how the Earth's atmosphere filters the IR radiation emitted by the Earth's surface and the role of the various greenhouse gases in that filtering process. The green line is the filter of the Earth's atmosphere without any greenhouse gases.

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.

Wake up and spread this information to your government!
