The world needs more CO2

Interview with Professor William Happer of Princeton University. Mr. Happer is a renowned physicist, specialized in the field of atomic physics, adaptive optics and spectrometry. This interview from 2015 is part of the series "Conversations that Matter."

Some quotes from this interview:

04:55 - "There is very little evidence that humans are making much impact [on the climate] and as far as CO2 is concerned witch is the major focus, that's probably more good than bad."

05:24 - "I know a lot about CO2 compared to most climate scientists because we make CO2 lasers. CO2 is a very interesting molecule, in particular, the model of CO2 that contributes to global warming. CO2 is a rod and it bends up and down, up and down and it's that bending motion that causes global warming. But that is such a strong absorption that's it's saturated now so if you add more CO2 most of what you can do has already been done, there's still a little addition but not very much."
"If you have a barn and you want to paint it red, you know when you paint it once it may not be red enough if you paint it two or three times then it really looks red, after that if you add more red it doesn't make much difference. And that's sort of what CO2 is doing now, most of the easy absorption has been done and so if you add more CO2 you get a little broadening but I don't want to get too technical."

07:20 - remarks on the logarithmic scale of CO2 induced warming.

08:50 - CO2 is food for plants

10:30 - "We're in a CO2 famine, we have too little CO2."

11:00 - CO2 was measured in thousands of parts per million, not hundreds. "Plants have envolved when there was a lot of CO2 to eat, now they don't have enough."

12:20 - There is no "social cost of carbon. The social cost is negative (...) it's a net contributor to agricultural productivity."

14:30 - There is no downside to CO2. This initial argument against CO2 was that there were to be a rapid global warming. It hasn't happened. It's clear that the models have enormously exaggerated it's warming potential.

15:00 - "I mentioned the saturation of CO2 (...) They noticed early on that CO2 has this 'problem', it was disappointing that it didn't make much difference so they invented all sorts of feedback mechanisms that would amplify the effect of additional CO2. Water vapor, clouds, all sorts of things were supposed to be triggered by this CO2. They don't seem to be happening.

15:30 - Water vapor is the main greenhouse gas. Water vapor and clouds.

15:50 - "The most honest modelers try to include clouds, but that's very primitive. Rough estimates. Nothing more."

17:50 - "Antarctic ice is probably growing (...) that's not supposed to happen according to the models, but it is happening."

18:40 - The Arctic is an ocean, the situation is completely different than at the South Pole. The Arctic ice is determined by ocean currents and not the air temperature.

21:00 - Climate models are group-think. They never looked at the world, they looked at other models and they say "look how good we are we're all getting the same answers, that must be right." They adjusted the parameters to get the same answers.

22:00 - "I don't think there's anything to worry about from more CO2. I think more CO2 to be good for the world. Our great-great-grandchildren will look back and say; 'Thank God we have all this CO2, what foresighted people our ancestors were.'"

22:30 - "Environalism should be looking at things that make a difference. Cleaning up real things that make a difference."

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.

Climate change seen from a historical perspective.

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.
