The climate during the Holocene

11/09/2018 21:00 - Posted by Tom van Leeuwen
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 it's 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?

National Geographic and the Amazon

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."

The "Green Lungs of the Earth" Myth

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.

The myth:

Woods, forests and jungles are Earth's "Green Lungs" that generate and produce the oxygen we need to breath and live.

Glacier Logic

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."

Climate models

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.

450 non-warming graphs and papers

Notrickszone presents a collection of 450 peer-reviewed scientific papers that question Global Warming Part 1 / Part 2. The collection contains a representative graphic from each paper. For some of the papers, a short excerpt of the conclusions is added.

Most of the papers have been written after the year 2000. They contain studies from the whole Holocene interglacial, but most of the work concentrates on the last 2,000 years.

Failed predictions

Since the start of the Global Warming scare numerous predictions have been made about all kind 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.

Sustainable - Contamination

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".

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.

The human impact

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.

Natural processes

1.- Every day the temperature varies between day and night, depending on where you live, about 10 °C. That is a natural process.

2.- Every year the temperature varies between summer and winter, depending on where you live, about 20 °C. That is a natural process.

The Ordovician Ice Age

Some 440 million years ago, global temperatures dropped sharply and the Earth entered in an Ice Age.

The Ordovician Ice age was so severe that it triggered a massive extinction event that caused the loss of 85% of marine animal species and 26% of animal families.

All this happened at between 8 and 12 times the current CO2 levels. Not by warming, but by cooling.

This completely contradicts the hypotsis promoted by the IPCC, the UN and your national government that CO2 warming is the main climate driver and that even just doubling the current CO2 levels would lead to catastrophic global warming. Exactly the opposite happened 440 million years ago.

2018 - The year without violent tornados in the US

Climate alarmists, the UN and your government warn us that when CO2 levels go up, more extreme weather events will take place.

And again, they have it all backwards. Despite record high CO2 levels, 2018 is the first year on record without any violent tornados in the United States.

This of course does not mean anything at all, but it is strange that what they are so sure of -and for which they warn us with so much emphasis- doesn't happen, while exactly the opposite does happen. They will not be wrong after all? Or will they?

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 in order to decide of 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.

A clean atmosphere causes global warming

When the atmosphere is clean, more sunlight will come in, warming the earth.

On Sept. 27th 2015, millions of people around the world watched the Moon pass through the shadow of our planet. Most agreed that the lunar eclipse was darker than usual. Little did they know, they were witnessing a sign of global cooling.

Ancient mammal extinction due to lack of CO2

During decades, researchers have blamed our ancestors for the extinction of large prehistoric mammals in Africa. New research points in a different direction. Most likely dangerously low CO2 concentrations have led to the extinction of large ancient mammals in Africa, over the last 4.6 million years.

Tyler Faith, curator of archaeology at the Natural History Museum of Utah and assistant professor in the Department of Anthropology at the University of Utah, led the study that was published in the journal Science.

IPCC more cynical than ever

The complete title of the latest IPCC report is: "Global warming of 1.5 °C - An IPCC Special Report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty".


This is a political report. There is no scientific proof in the whole report that shows a link between CO2 and rising temperatures. There's not even a proof that rising temperatures are dangerous. The temperature levels for which they warn are below the normal, natural levels during most of the Holocene. There is nothing dangerous about that. Humanity owes its development precisely to the higher temperatures of this interglacial.

New York Times publishes fake climate data

The New York Times website is running an interactive tool that enables you to check how much hotter your hometown is today, compared to the year when you were born.

Tony Heller tested the tool for the city of Brinkley, Arkansas, with the following surprising results.

NASA: Lack of sunspots to bring record cold

“The sun is entering one of the deepest Solar Minima of the Space Age,” wrote Dr Tony Phillips just six weeks ago, on 27 Sep 2018.

Data from NASA’s TIMED satellite show that the thermosphere (the uppermost layer of air around our planet) is cooling and shrinking, literally decreasing the radius of the atmosphere.

Climate change to cause 'dramatic' beer shortages

Last month, researchers from the University of East Anglia (the university that brought us Climategate) published this study, assessing the impact of drought and heat extremes caused by Climate Change on barley yields.

Their conclusions:

The year the Maldives drowned

The Maldives is a South Asian country, located in the Indian Ocean. According to Wikipedia: “With an average ground-level elevation of 1.5 metres (4 ft 11 in) above sea level, it is the world's lowest country, with even its highest natural point being the lowest in the world, at 2.4 metres (7 ft 10 in)”. It consists of 1196 small islands.

In 1988, environmental experts warned that the whole country was at risk to be completely covered by rising sea levels within 30 years.

Executive Summary

This study looks at the positive environmental effects of carbon dioxide (CO2) emissions, a topic which has been well established in the scientific literature but which is far too often ignored in the current discussions about climate change policy.

All life is carbon based and the primary source of this carbon is the CO2 in the global atmosphere and hydrosphere.

As recently as 18,000 years ago, at the height of the most recent major glaciation, atmospheric CO2 dipped to its lowest level in recorded history at 180 ppm, low enough to stunt plant growth. This is only 30 ppm above a level that would result in the death of plants due to CO2 starvation.

Non-existing thermometers measure record heat

The first map shows the average global temperatures for the month of September 2018. That looks terrifying, so much warming, so many record temperatures!

The second card shows reality. The grey and white areas indicate where no measurements have been taken. In Arabia and East Siberia the heat would have broken all records, while in reality there are no thermometers. In large parts of Brazil and Africa, non-existing thermometers measured temperatures that were far above the average.

They just make it up!

IPCC – Back to the Little Ice Age?

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.

Wildfires and climate change

We are told that forest fires are on the rise. It would be our fault by using fossil fuels.

Exactly the opposite is true. It is precisely thanks to the use of fossil fuels that we are able to fight forest fires with fire engines, helicopters and aircraft, which has led to a reduction of 80% of the burned area over the last 90 years in the United States.
The slight increase from 1995 onwards is due to a reduction in forest maintenance, enforced by environmental groups in an attempt to protect certain fauna.

Is climate change the culprit causing California’s wildfires?

Snow surface grows since 1990

Snow disappears when the temperature rises above 0 °C. This means that the snow surface gives an indication of the temperature. Furthermore, it is much easier to measure than the average temperature itself.

In the graph we see the snow-covered land area of the Northern Hemisphere since 1990.
While the CO2 concentration of the atmosphere increased by about 17% in that period -from 350 to 410 parts per million- the snow surface grew by an average of 16 thousand square kilometers per year, exactly the opposite of what was to be expected from the greenhouse gas hypothesis.

This is an indication that the greenhouse effect of CO2 is already saturated, as scientists from NASA already proved in the 1970s. CO2 is a greenhouse gas, but the addition of more CO2 to the atmosphere does not result in a significant increase in temperature.
