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.
CO2 is a greenhouse gas but it's warming capability is almost saturated. Even at much lower concentrations it absorbs almost all energy it can absorb, so adding more CO2 to the atmosphere has no measurable effect on global temperatures.

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".

Really.

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:
"Average yield losses range from 3% to 17% depending on the severity of the conditions. Decreases in the global supply of barley lead to proportionally larger decreases in barley used to make beer and ultimately result in dramatic regional decreases in beer consumption (for example, -32% in Argentina) and increases in beer prices (for example, +193% in Ireland). Although not the most concerning impact of future climate change, climate-related weather extremes may threaten the availability and economic accessibility of beer."

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.

The positive impact of human CO2 emissions

The Positive Impact of Human CO2 Emissions on the Survival of Life on Earth
Patrick Moore, PhD
Co-Founder of Greenpeace

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.

Is the global temperature record credible?

In this video Tony Heller shows us how NASA changes it's data record over time. The cooling that took place from around 1945 until 1975 has simply been ereased from the historical temperature data they publish now. Other agencies follow suit, they make similar adjustments to their own data sets, creating a fake sense of consensus.
Tony proves the cooling really happened showing historical newspaper articles. The data can be tampered, but the written history can not!

A must see! Tony Heller - Is the global temperature record credible?
