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

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.

GLOBAL Temperature Drops By 0.4°C In Three Years

NOT A LOT OF PEOPLE KNOW THAT

From David Whitehouse:

In a press release the World Meteorological Organisation said,

The main message was echoed by others, such as the BBC.

Likewise the Guardian:

It all goes to show how temperature data can be misrepresented if you don’t show the temperature data itself.

Fig 1 is the HadCRUT4 monthly global temperature from the UK Met Office.

As you can see a graph tells a very different story. The past decade has a climate change contribution but what elevates the past four years above the previous ones is an El Nino event, the strongest one on record. As we have said many time before an El Nino is not a climatic phenomenon, it is weather. What’s more, after its peak in 2016 the global temperature has fallen by around 0.4° C. The past four years being the warmest on record is true, but it has…

GLOBAL Temperatures Rose As Cloud Cover Fell In the 1980s and 90s

Global Temperatures Rose As Cloud Cover Fell In the 1980s and 90s

Figure 1a showing the ISCCP global averaged monthly cloud cover from July 1983 to Dec 2008 over-laid in blue with Hadcrut4 monthly anomaly data. The fall in cloud cover coincides with a rapid rise in temperatures from 1983-1999. Thereafter the temperature and cloud trends have both flattened. The CO2 forcing from 1998 to 2008 increases by a further ~0.3 W/m2 which is evidence that changes in clouds are not a direct feedback to CO2 forcing.

Good find. Makes sense.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

We’ve been discussing the sudden rise in UK and European temperatures in the 1990s, and I was reminded about a study undertaken by Clive Best and Euan Mearns looking at the role of cloud cover four years ago:

image

Clouds have a net average cooling effect on the earth’s climate. Climate models assume that changes in cloud cover are a feedback response to CO2 warming. Is this assumption valid? Following a study with Euan Mearns showing a strong correlation in UK temperatures with clouds, we looked at the global effects of clouds by developing a combined cloud and CO2 forcing model to sudy how variations in both cloud cover [8] and CO2 [14] data affect global temperature anomalies between 1983 and 2008. The model as described below gives a good fit to HADCRUT4 data with a Transient Climate Response (TCR )= 1.6±0.3°C. The 17-year hiatus in…

GLOBAL TEMPERATURE PLUNGE : Coolest September In The Last 10 Years

GLOBAL atmospheric temperatures continue their rapid decline off the record heights of the 2016 super El Niño, despite record and rising CO2 emissions.

UAH global average lower tropospheric temperature (LT) anomaly for September, 2018 was +0.14°C, down from +0.19°C in August:

Latest Global Average Tropospheric Temperatures

Since 1979, NOAA satellites have been carrying instruments which measure the natural microwave thermal emissions from oxygen in the atmosphere. The intensity of the signals these microwave radiometers measure at different microwave frequencies is directly proportional to the temperature of different, deep layers of the atmosphere. Every month, John Christy and I update global temperature datasets that represent the piecing together of the temperature data from a total of fifteen instruments flying on different satellites over the years. A discussion of the latest version (6.0) of the dataset is located here.

The graph above represents the latest update; updates are usually made within the first week of every month. Contrary to some reports, the satellite measurements are not calibrated in any way with the global surface-based thermometer records of temperature. They instead use their own on-board precision redundant platinum resistance thermometers (PRTs) calibrated to a laboratory reference standard before launch.

Latest Global Temps « Roy Spencer, PhD

THE September anomaly represents a 0.72°C drop since 2016 super El Niño heights, bringing temps down now to ~1988 levels.

DON’T expect the mainstream media to report in this anytime soon. They are only concerned about hot and climbing temperatures to push their  global warming climate change agenda.

Satellites Vs Thermometers?

SATELLITES

NASA’s MSU satellite measurement systems, generate the RSS and UAH datasets, which measure the average temperature of every cubic inch of the lower atmosphere, the exact place where global warming theory is meant to occur.

BEFORE 2016, UAH and RSS both tracked closely showing very little warming in their data sets which led to the identification and validation of “the pause” in global warming which has since become the subject of much research and debate in peer-reviewed scientific journals.

From the RSS website:

“The simulation as a whole are predicting too much warming” – RSS

HOWEVER, by 2016, Carl Mears, who is the chief scientist for RSS (Remote Sensing Systems) and who has used the pejorative “denialist” in various correspondence, decided that “the pause” was not a good look for the global warming narrative so RSS was massively adjusted upwards, conveniently eliminating “the pause” in the RSS dataset.

MEARS’ objectivity towards the business of global temperature data collection and reporting can be found in his commentary on his website:

MEARS then published a paper claiming that new and improved adjustments have “found” that missing warming.

UAH NASA SATELLITE (Featured)

UAH is the satellite data set featured in this post and is jointly run by Dr. John R. Christy –  Distinguished Professor of Atmospheric Science and Director of the Earth System Science Center at The University of Alabama in Huntsville. And Roy Spencer Ph.D. Principal Research Scientist at the University of Alabama in Huntsville.

SPENCER commentary on the divergence between RSS and UAH post “adjustment”:

“We have a paper in peer review with extensive satellite dataset comparisons to many balloon datasets and reanalyses. These show that RSS diverges from these and from UAH, showing more warming than the other datasets between 1990 and 2002 – a key period with two older MSU sensors both of which showed signs of spurious warming not yet addressed by RSS. I suspect the next chapter in this saga is that the remaining radiosonde datasets that still do not show substantial warming will be the next to be “adjusted” upward.

The bottom line is that we still trust our methodology. But no satellite dataset is perfect, there are uncertainties in all of the adjustments, as well as legitimate differences of opinion regarding how they should be handled.

Also, as mentioned at the outset, both RSS and UAH lower tropospheric trends are considerably below the average trends from the climate models.

And that is the most important point to be made.”

It’s hot in lots of places. Get over it. It’s August.

By the end of the month it will cool down. And by December it will be cold. This is Canada.

The current heat wave is not a sign of global warming. It’s a sign it’s summer.

In June, it was cooler than normal in lots of the places that are now so hot. How come the climate alarmists weren’t running around then flailing their arms in the air and shrieking about a coming ice age?

There were breathless stories in Calgary this week warning the city was in for its hottest four days in 35 years – more proof that Earth stands poised on the brink of a climate catastrophe.

Yet, if this time the cause is climate change, what caused the heatwave 35 years ago?

Couldn’t have been SUVs, pipelines or the oilsands.

HOTTEST YEAR EVAHH : Fourth-Warmest Year on Record? The Devil’s in the Details

CLAIMS of the “hottest year ever” tell us more about climate change marketing and PR than they do, actual science.

IN our schizophrenic, 24 hour news cycle and the era of internet clickbait, it serves the Climate Crisis Industry and those invested in man-made climate alarmism to produce headlines of “the hottest year ever” in order to push their political and ideological agenda…

THE Guardian’s Dana Nuttercelli is no stranger to pushing the ideological wheelbarrow of “hottest year evahh” hysteria…

THANK god for old-school meteorologists like Weatherbell’s Joe Bastardi, who cut through the cheap, lazy, clickbait alarmism to provide a scientific understanding of what really makes up “hottest year ever” claims such that we can use this knowledge to better predict weather and climate, rather than simply feeding the global warming hysteria beast for political, moral and financial gains.

Fourth-Warmest Year on Record? The Devil’s in the Details

Joe Bastardi · Jul. 30, 2018

I continue to examine the idea that relatively minute increases in water vapor brought on by cyclically warmed oceans are the reason for the earth’s warming. But the way warming is portrayed must be looked at closely. It is very real and adds to forecast problems, but as far as the hysteria you see whipped up in relation to mankind’s self-destructing, it’s just that to me — hysteria.

Let’s assume 2018 is the fourth-warmest on record. Most people live between 70°N and 70°S.

DISGRACE : Shameless Link Between Suicide And Climate Change, Circulating The Mainstream Media’s Echo Chamber

THE Death of Mainstream Media - Suicide blog CLIMATISM.png


SINCE Climatism reported on the lazy and disrespectful link between suicide and climate change two days ago, a study has now surfaced out of the warmist, Nature Climate Change…

*

NOT surprisingly, the mainstream media has jumped all over this single study like a pack of hungry wolves, in a blatant attempt to link their emotionally-charged climate change cause with the genuinely emotional and tragic issue of suicide.

“The study, published today in the journal Nature Climate Change, concluded that projected temperature increases over the next few decades could lead to an additional 21,000 suicides in the United States and Mexico by 2050.”

THE STUDY

*

THE studies “could, maybe, might” findings are based on the highest emissions scenario, RCP8.5, pushed out to the arbitrary, unaccountable and ‘sciencey’ date of 2050…

“We project that unmitigated climate change (RCP8.5) could result in a combined 9–40 thousand additional suicides (95% confidence interval) across the United States and Mexico by 2050, representing a change in suicide rates comparable to the estimated impact of economic recessions, suicide prevention programmes or gun restriction laws.”

THE study also took into account seasonal variation, levels of poverty, the news of celebrity suicides and even depressive social media commentary that can lead to more death…

“Analysis of depressive language in >600 million social media updates further suggests that mental well-being deteriorates during warmer periods.”
