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
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.
More in the role of CO2
as a greenhouse gas: Why did the warming stop?
Professor at the Geophysical Sciences department at the University of Chicago David Archer describes the band-saturation of the CO2
greenhouse effect. After that, everything goes wrong.
The first part of the lecture is very informative. Professor Archer explains in great detail how the CO2
greenhouse absorption works, it's logarithmic nature and the band saturation. He even shows on a working instance of the MODTRAN model how adding the first ppm of CO2
to the atmosphere has a huge impact on the atmosphere's energy balance. Adding more CO2
, the effect fades away.
Hydropower is one of the cleanest energy sources available. The only downsides known so far are the impact on the landscape and the risk of a dam breaking due to earthquakes. Carefully choosing the locations and high construction standards are needed to solve these problems.
Besides electricity generation, dams also help to regulate the water flow in the rivers, making them better navigatable and useful for irrigation.
So, overall it seems to be quite positive, but recent research has "discovered" a new downside to hydroelectricity and it's a usual suspect: Greenhouse gasses
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:
For many people, a logarithmic relationship can be a fairly abstract concept. It is hard to imagine the implication that it has on the strength of the greenhouse effect that corresponds to the amount of CO2
that humanity emits into the atmosphere. Here we present a visualization to explain in a simple way what we are talking about.
is a greenhouse gas. The presence of CO2
in the atmosphere traps a part of the infrared radiation that the Earth's surface emits into space. The total greenhouse effect of the Earth's atmosphere is about 30 °C, without this effect, the temperature would be -15 °C instead of +15 °C, the actual current average temperature.
Water vapor is the most important greenhouse gas. CO2 provides 3 °C of heating, that is, 10% of the total effect
When the concentration of CO2
increases, its greenhouse effect also increases, but not in a linear fashion, but logarithmically
. For each increase in concentration, the effect on temperature is less and less.
Water vapor is the single most important greenhouse gas. It makes up 80% to 90% of the total greenhouse effect of the Earth's atmosphere.
Climate models depend on water vapor as a positive feedback for supposed CO2
warming. In these models, CO2
causes a tiny warming that causes the relative atmospheric humidity to increase. That increase in water vapor produces the catastrophic warming they predict.
The problem is that in the real world, while atmospheric CO2
-concentrations increased by almost 30% since the end of World War II, the relative atmospheric humidity has been stable at low altitudes and has even decreased at higher altitudes.
This picture is part of a very interesting paper
by independent researcher Brian Catt
about the effects of magma and volcanism on the ocean heating
through glaciation cycles.
It shows the temperature for the last four interglacial periods. Each interglacial has it's own color:
- Red - The Holocene, from 18,000 years ago until today ("We are here...")
- Green - The Eemian , from 136,000 years ago until 110,000 years ago
- Blue - Interglacial "MIS 7", from 245,000 years ago until 219,000 years ago
- Purple - Interglacial "MIS 9", from 343,000 years ago until 317,000 years ago
During the 1970's, there was a "scientific consensus" on catastrophic Global Cooling. This clearly shows that mankind, heavily influenced by the mainstream media, overreacts to normal, natural climate variations.
The Eemian Interglacial was a warm period that lasted from ca. 130,000 – 115,000 years ago and was followed by the most recent glacial period (Weichselian/Wisconsinan), which lasted until about 11,000 years ago when the current warm period, the Holocene, began. So, it's the last interglacial before the current one.
The interglacial is named after the River Eem in the Netherlands because it was first recognized from boreholes in the area of the city of Amersfoort, located in the Eem Vally. Studying the Eemian is very important because the continental configuration of the Earth was very similar to the current situation. This means that ocean currents were very likely to be the same as today.
New research from the Niels Bohr Institute at the University of Copenhagen indicates that atmospheric CO2
concentrations follow temperature, and not the other way around.
“Our analyses of ice cores from the ice sheet in Antarctica shows that the concentration of CO2
in the atmosphere follows the rise in Antarctic temperatures very closely and is staggered by a few hundred years at most,” explains Sune Olander Rasmussen, Associate Professor and centre coordinator at the Centre for Ice and Climate at the Niels Bohr Institute at the University of Copenhagen
Warmer water can contain less CO2
, so when oceans warm up they release CO2
to the atmosphere.
This is in clear contradiction with the CO2
-hypothesis that says that CO2
Newspapers and websites from all over the world tell us that their country / region / continent is warming "faster", or even "twice as fast" as the global average
. This faster than average warming is reported for:
- The Arctic
- The Middle East
- The Tropical Andes
- The Earth's mountains
- The Earth's lakes
- The Earth's deserts
- The Gulf of Maine
- Japanese waters
- The Indian Ocean
- The Korean Peninsula
- The Great Lakes
- Subtropical areas
- The Red Sea
- Northeastern part of the United States
- West Antactica
While in some cases this might be true, like Singapore
due to the Urban Heat Island
effect, it's obviously impossible to be true for all these places because they cover almost the entire landmass of the Earth.
The webpages depicted in the above image really exist. Here they are
, together with some bonus links:
A clarification to begin with. The title of this article and the text of the image must be understood as: "Adding more CO2
to the currently existing CO2
concentration in the Earth's atmosphere has no measurable impact on the average temperature".
There has never been conclusive scientific evidence for the CO2-hypothesis
which says that human emissions enhance the greenhouse effect, resulting in global warming. On the contrary, all evidence and rational considerations point in the opposite direction, namely that this hypothesis must be refuted.
Here's an overview:
Did you know that ...
- Oxygen feeds fires while CO2 extinguishes fires?
- Oxygen causes rot and oxidation while CO2 feeds plants?
- All life on Earth is as dependent on CO2 as it is on oxygen?
- The greenhouse effect of water vapor is 10 times as strong as the CO2 greenhouse effect?
- Oxygen does not heat the Earth and neither does CO2?
- The Earth's atmosphere contains 525 times as much oxygen as CO2?
- When life on Earth started, the CO2 level was more than 10 times as high as it is today?
- Without the human burning of fossil fuels, life on Earth would have slowly started to die out due to lack of CO2?
The demonization of CO2
is an attack against human development. In the longer term it is an attack against all life on Earth.
Did you know that?
The combined mass of the Earth's oceans is 1.35 x 1024
The specific heat of ocean water is 3.993 Joule / gram / Kelvin.
So, it takes 5.39055 x 1024
Joules to warm the oceans 1 Kelvin.
The total mass of the Earth's atmosphere is 5.1480×1021
The specific heat of the atmosphere is 1.005 Joule / gram / Kelvin.
So, it takes 5.17374 x 1021
Joules to warm the atmosphere 1 Kelvin.
Earlier this week, a group of "more than 500 knowledgeable and experienced scientists and professionals in climate and related fields" sent this urgent message to the United Nations declaring there is no climate emergency
. They urge to review the climate models on which international policy is based, calling these models "unfit for their purpose" and "Immature"
The group invites the UN to organize
together "a constructive high-level meeting
between world-class scientists on both sides" on climate change.
The complete letter
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.
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.
National Geographic made a first step in the right direction by admitting that the Oxygen balance of the Amazon rainforest equals zero
"However, the figure—which has earned the forest the title “lungs of the Earth”—is a gross overestimate. As several scientists have pointed out in recent days, the Amazon’s net contribution to the oxygen we breathe likely hovers around zero."
This must be the environmental myth with the deepest roots of them all (pun intended). It's compulsory subject matter in public schools around the globe, it's passed from generation to generation and if you dare to question it in public, disbelieve, rejection, jeering and even exclusion from the conversation will be your treat. That's the typical way people react when their beliefs and primary "knowledge" are challenged.
Woods, forests and jungles are Earth's "Green Lungs" that generate and produce the oxygen we need to breath and live.
Last month, the New York Times website published a page titled "Glaciers Are Retreating. Millions Rely on Their Water."
It shows a dramatic image, zooming out of a person walking down a dry glacier bed with the following text:
"In Central Asia, a warming climate is shrinking the Tuyuksu glacier. It’s losing ice every year.
Around the world, vanishing glaciers will mean less water for people and crops in the future."
Computer models are something magical. As powerful computers, located at famous universities and authoritative government agencies are involved, model output is often considered to be a substitute for reality
But it's not.
Since the start of the Global Warming scare, numerous predictions have been made about all kinds of things related to the climate. As this scam is going on for over 30 years now some of those predictions have reached their due date and the time has come to check the results.
You can't make this up
Firewood is considered "biomass", and politicians seem to believe that the CO2
produced by burning biomass is different from CO2
produced by burning fossil fuels. They also believe CO2
is a dangerous contaminant.
So, according to the UN, the IPCC and your national government (depending on where you live), firewood cooking is considered "sustainable", while cooking with natural gas is "contamination".
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
Humanity tends to overestimate its influence on the environment. In reality, the influence of human activity is tiny compared with the enormous forces of natural processes. Here we make a rough comparison between the total amount of energy humanity has consumed since the Industrial Revolution and the amount of energy needed for a natural process: the end of a glacial period.
