PEER-REVIEWED SCIENCE : The Medieval Warm Period Was Indeed Global And Warmer Than Today

THE Medieval Warm Period - A global Phenomenon - CLIMATISM

The Medieval Warm Period – A Global Phenomenon


No matter if the science of global warming is all phony…
climate change provides the greatest opportunity to
bring about justice and equality in the world
.”
– Christine Stewart,
fmr Canadian Minister of the Environment

We’ve got to ride this global warming issue.
Even if the theory of global warming is wrong,
we will be doing the right thing in terms of
economic and environmental policy.

– Timothy Wirth,
President UN Foundation

WHEN prosecuting the case for “unprecedented” man-made Global Warming, the first thing you need to make sure of is that no recent climate era was as warm or warmer than the present, even if that means having to rewrite the past to fit your narrative.

THE Medieval Warm Period, also known as the Medieval Climate Optimum (due to conditions favoured for crops, life and civilisation to thrive) existed a short time ago in the climate record, from c. 950 to c. 1250., and has remained a thorn in the side, ever since, for today’s Global Warming Climate Change activist movement.

IN the 1990 IPCC report, the Medieval Warm Period was much warmer than the late 19th century:

THE IPCC’s 1990 report dives deeper into the reality of the Medieval Warm Period and provides an insight into the cause of these warming periods:

“This period of widespread warmth is notable in that there is no evidence that it was accompanied by an increase of greenhouse gases.

IPCC WG1 Report 1990 (p202)

BY the 2001 IPCC report, the Medieval Warm period disappeared and became much cooler than the late 20th century:

BY pure coincidence, in the year 1995 the IPCC made a decision to make the Medieval Warm Period disappear:

Video of Dr David Deming’s statement to the U.S. Senate Committee on Environment & Public Works on December 6, 2006. Dr Deming reveals that in 1995 a leading scientist emailed him saying “We have to get rid of the Medieval Warm Period”. A few years later, Michael Mann and the IPCC did just that by publishing the now throughly discredited hockey stick graph.

IN case you missed it…

“I had another interesting experience around the time my paper in Science was published. I received an astonishing email from a major researcher in the area of climate change. He said, “We have to get rid of the Medieval Warm Period.””

The existence of the MWP had been recognized in the scientific literature for decades. But now it was a major embarrassment to those maintaining that the 20th century warming was truly anomalous. It had to be “gotten rid of.””

THE MEDIEVAL WARM PERIOD : GLOBAL and PEER REVIEWED

ACCORDING to multiple lines of “peer-reviewed science”, the Medieval Warm Period was indeed ‘global’ and was as warm, if not warmer than today.

THE ‘INCONVENIENT’ PAST

THERE is absolutely nothing unusual about today’s so-called Global Warming aka Climate Change.

LOOK at how many periods of warmth our planet has enjoyed during the past 10,000 years alone.

CIVILISATIONS flourished during those warm periods (“climate optimums”), and collapsed when they ended.

DID humans cause the Minoan warm period of about 3,300 years ago?

DID humans cause the Roman warm period of about 2,100 years ago?

DID humans cause the Medieval warm period of about 1,000 years ago?

WHAT about all of those other warm periods? Should we blame Fred Flintstone, perhaps?

IF the downward trend in temperature of the past 3,300 years continues, we could be in a heap of trouble. While our leaders keep on wringing their collective hands over global warming, we could be blindsided by an ice age.

ALL this talk about human-caused global warming is sheer nonsense, if not downright fraud. The record shows that both periods of warmth – and periods of cold – hit our planet with almost consistent regularity.

Climate Revisionism 101 : “We Have To Get Rid Of The Medieval Warm Period”

WHEN you are a man-made global warming alarmist prosecuting your case as “unprecedented”, you need to make sure that no recent climate era was as warm or warmer than the present, even if that means having to rewrite the past to fit your theory.

THE Medieval Warm Period, also known as the Medieval Climate Optimum (for obvious reasons) existed a short time ago in the climate record, from c. 950 to c. 1250., and has remained a thorn in the side for modern “global warming” catastrophists…

HOTTEST Arctic Ever? Arctic Climate Change Fairytales vs. Reality

EXCELLENT piece by our friend and environmental scientist Vijay Jayaraj on the recent mass hysteria over the supposed “hottest day evah” in the Arctic.

Vijay’s piece, featured in Town Hall, demonstrates how the Climate Crisis Industry will latch on to any daily (hot) weather event in order to push their CAGW agenda yelling “GLOBAL WARMING” without any consideration for historical reference or indeed common sense…

“Those who count the Arctic warmth as evidence for global warming should count the Eurasian [cold] as evidence for global cooling”


Vijay Jayaraj
Vijay Jayaraj | Posted: Mar 06, 2018 12:01 AM

This week, social media and mainstream media were abuzz with news about the record Arctic heat and how we humans are destroying our planet through climate change.

While we brace for a barrage of climate doomsday news, here is the actual reality of climatic conditions at the Arctic and reasons why we are not in imminent danger.

On 26 February, temperatures in some regions of the Arctic hovered around the freezing point (zero degree Celsius)—a record high for this time of year in the satellite era temperature readings (which began in the late 1970s).

But the current rise in Arctic temperature is due not to changes in global average temperature but to changes in regional weather patterns. Changes in the weather system across the Scandinavian region are pushing very warm, moisture-laden Atlantic air into the Arctic and very cold Arctic air into Northern Eurasia, leading much of Europe into a deep freeze this week.

(Those who count the Arctic warmth as evidence for global warming should count the Eurasian code [cold] as evidence for global cooling.)

The same has been prevalent over North America this week, resulting in a colder than normal winter in some parts while temperatures soar towards the east coast.

To understand the sudden peak in arctic temperatures, it is critical to analyze two key elements associated with the Arctic climate: 1. past temperature trends, and 2. the historic variations of the sea ice cover in the Arctic.

Temperature records for the Arctic reveal that the current rise in temperature is not unusual.

The weighted Arctic (70–90oN) monthly surface air temperature anomalies (from HadCRUT4) show that average surface temperatures in the Arctic have not increased significantly since the 1930s.

Long-term (1880–2018) Arctic surface annual air temperature series from Nuuk, Greenland, show that the high temperatures in the recent years are not significantly higher than the previous 14 decades.

Climate alarmists argue that these high temperatures lead to extreme reduction in sea ice levels and upset the eco-system of the planet.

However, sea ice variations reveal a similar pattern to that of temperature—there has been no extreme reduction of sea ice in recent decades.

The latest studies on Arctic sea ice indicate that sea ice cover during the 20th century did not depart significantly from the record sea ice levels during the Little Ice Age (1600–1700 AD).

And understandably, the sea ice cover was at its 2000-year low during the Medieval Warm Period (1000-1200 AD) and during the Roman Warm Period (around 0 AD).

If one were to consider longer temperature data series, such as the entire Holocene (the warm climatic era that constitutes the last 11,700 years approximately), we have no reason to panic about sea ice cover.

Sea ice cover in the 20th century was at its highest ever (excluding the Little Ice Age of 16thcentury) in the last 11,000 years.

Solar activity, and not carbon dioxide, was found to be the main reason for changes in the historical sea ice variations.

The current sea ice loss is not extraordinary by any means, and the Arctic ecosystem survived through much lower ice cover extent in the past 2000 years.

Lying about sea ice and temperatures is not new for the climate alarmists, and their hypocrisy will surely reach new heights this spring.

MEANWHILE, as the climate mafia bloviates inside their WEATHER = CLIMATE bubble, the other conveniently forgotten pole, Antarctica, continues its long 40 year+ cooling trend, gaining ice mass despite record and rising CO2 levels and claims of The Hottest Years Evah

From the abstract:

Mass changes of the Antarctic ice sheet impact sea-level rise as climate changes, but recent rates have been uncertain. Ice, Cloud and land Elevation Satellite (ICESat) data (2003–08) show mass gains from snow accumulation exceeded discharge losses by 82 ± 25 Gt a−1, reducing global sea-level rise by 0.23 mm a−1.

YES! The Climate Changes

climate-changes

People who follow the “climate change” mantra know exactly what to think and feel about the topic but have no concept of the facts. This is problematic as the inability to recognise and compare historical evidence against real-world data, ferments a groupthink hysteria that global warming climate change is unprecedented and caused solely by evil humans.

This is simply not true. Climate change, extreme or otherwise, has been happening for billions of years, and yes, well before industrialisation.

Climate group-thinkers are very strong on opinion and shonky on facts. They know what they should think about global warming climate change, but have no idea why they should think it.

This five minute US congressional video highlights brilliantly the fact-free, pseudoscientific groupthink zealotry that has so dangerously infected the gullible, and inspired a trillion dollar faith-based industry we know as “climate change”.

Be sure to watch this ‘ouch’ moment c/o Barack Obama’s Chief Climate Advisor… 🤔

Obama’s Chief Climate Adviser on 1920s global warming: ‘It is a crisis we’re trying to address’ – YouTube

The article, which was written by the Associated Press, appeared in scores of newspapers around the country in November of 1922. A researcher named John Lockwood found the article archived at the Library of Congress in 2007.

The article was based on a report that appeared in the November 1922 edition of the Monthly Weather Review. The original report says an expedition was sent by the Norwegian Department of Commerce to the Arctic Circle to survey land and to make “oceanographic investigations.” According to excerpts from the report:

“The Arctic Ocean is warming up, icebergs are growing scarcer and in some places the seals are finding the water too hot, according to a report to the Commerce Department yesterday from Consul Ifft, at Bergen, Norway.

“Reports from fishermen, seal hunters and explorers, he declared, all point to a radical change in climate conditions and hitherto unheard-of temperatures in the Arctic zone. 

“Exploration expeditions report that scarcely any ice has been met with as far north as 81 degrees 29 minutes. Soundings to a depth of 3,100 meters showed the gulf stream still very warm.

Great masses of ice have been replaced by moraines of earth and stones, the report continued, while at many points well known glaciers have entirely disappeared.

“Very few seals and no white fish are found in the eastern Arctic, while vast shoals of herring and smelts, which have never before ventured so far north, are being encountered in the old seal fishing grounds.”

Ice conditions were exceptional. In fact, so little ice has never before been noted … This is the farthest north ever reached with modern oceanographic apparatus.

“…It is of interest to note the unusually warm summer in Arctic Norway and the observations of Capt. MartinIngebrigstaen, who has sailed the eastern Arctic for 54 years past.

“He says that he first noted warmer conditions in 1918, that since that time it has steadily gotten warmer, and that to-day the Arctic of that region is not recognizable as the same region of 1868 to 1917.”

Washington Post story from 1922 stating the Arctic was getting warmer and ice was melting.

Massive Cover-up Exposed: 285 Papers From 1960s-’80s Reveal Robust Global Cooling Scientific ‘Consensus’

The real ‘deniers’ if you like.

Worse still, these guys, Connolley, Schmidtt and Mann are history ‘re-writers’.

There truly are no boundaries when formulating the climate scam.

NOT A LOT OF PEOPLE KNOW THAT

Kenneth Richard provides a detailed and damning account in NoTricksZone of the attempt to cover up global cooling in the 1970s by William Connolley:

Beginning in 2003, software engineer William Connolley quietly removed the highly inconvenient references to the global cooling scare of the 1970s from Wikipedia, the world’s most influential and accessed informational source.

It had to be done. Too many skeptics were (correctly) pointing out that the scientific “consensus” during the 1960s and 1970s was that the Earth had been cooling for decades, and that nascent theorizing regarding the potential for a CO2-induced global warming were still questionable and uncertain.

Not only did Connolley — a co-founder (along with Michael Mann and Gavin Schmidt) of the realclimate.com blog — successfully remove (or rewrite) the history of the 1970s global cooling scare from the Wikipedia record, he also erased (or rewrote) references to the Medieval…
