Climate change to cause 'dramatic' beer shortages



11/20/2018 19:05 - Posted by Tom van Leeuwen
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 truth is quite different. As we see in the figure above this article, barley yields have doubled over the last 60 years from 1,500 kg per hectare in 1960 to over 3,000 kg per hectare in 2017.
As was to be expected, the yield growth seems to be in perfect correlation with the increase of CO2 concentrations, an essential gas for life on this planet.


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.
