The climate during the Holocene

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 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?
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
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.
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 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.
