IPCC – Back to the Little Ice Age?



11/15/2018 19:20 - Posted by Tom van Leeuwen
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.


It’s not until page 6, after repeating “pre-industrial levels” a large number of times, that the phrase is substituted once, and only once, by “the 1850–1900 period”, somehow indicating that is the pre-industrial period they're refering to. After that it’s back to the very unscientific “pre-industrial levels” wording.
Clearly, the IPCC wants to make sure to frame that the supposed warming has something to do with industrialization.

 
What they do not tell you is that the 1850-1900 period marks the end of the “Little Ice Age”, the coldest period of the Holocene (the last 10,000 years.)
Wikipedia describes that period as “Europeans sought explanations for the famine, disease, and social unrest that they were experiencing”, and “… consequences of the Little Ice Age: livestock epidemics, cows that gave too little milk, late frosts, and unknown diseases.

Is that the type of world the IPCC wants to lead us back to?

The warming we're experimenting is nothing more than the return to the normal situation during the Holocene, leaving behind the extremes of the Little Ice Age.

On a brighter side, the IPCC now forecasts 26-77 cm sea level rise until 2100 instead of the 26-82 cm they predicted 5 years ago. Maybe they need a couple of additional special meetings at exotic locations in order to discover that the sea level rise is not accelerating at all and that all of the forecasts that were made 30 years ago have failed.


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 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.

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.
