Climate Catastrophe In The 17thC – Geoffrey Parker

by P. Homewood, Apr 9, 2021 in NotaLotofPeoppleKnowThat


 

 

Amazon’s blurb sets the scene:

Revolutions, droughts, famines, invasions, wars, regicides – the calamities of the mid-seventeenth century were not only unprecedented, they were agonisingly widespread.  A global crisis extended from England to Japan, and from the Russian Empire to sub-Saharan Africa. North and South America, too, suffered turbulence. The distinguished historian Geoffrey Parker examines first-hand accounts of men and women throughout the world describing what they saw and suffered during a sequence of political, economic and social crises that stretched from 1618 to the 1680s. Parker also deploys scientific evidence concerning climate conditions of the period, and his use of ‘natural’ as well as ‘human’ archives transforms our understanding of the World Crisis. Changes in the prevailing weather patterns during the 1640s and 1650s – longer and harsher winters, and cooler and wetter summers – disrupted growing seasons, causing dearth, malnutrition, and disease, along with more deaths and fewer births. Some contemporaries estimated that one-third of the world died, and much of the surviving historical evidence supports their pessimism.

 

 

Amongst these catastrophic events, Parker lists:

 

Early 17thC

1) West Africa, from the Sahel in the north to Angola in the south, suffered a prolonged drought between 1614 and 1619.

2) Catalonia suffered “the year of the flood” in 1617.

3) All Europe experienced an unusually cold winter in 1620/21, when many rivers froze so hard for 3 months that they could bear the weight of loaded carts; even the Bosphorus froze, an unheard of event.

4) Japan suffered its coldest spring of the century in 1616, while the sub tropical region of Fujian in China had heavy snowfall two years later, another extremely rare event.

5) Droughts in five years out of six between 1616 and 1621 almost the destroyed the new colonies in Virginia.

6) After a few better years, the summer of 1627 in Europe was the wettest for 500 years, followed by the “year without a summer” in 1628, when it was so cold that many crops never ripened.

7) Between 1629 and 1632, much of Europe suffered excessive rains, followed by drought.

8) Conversely, northern India suffered a “perfect drought” in 1630/31, followed the next year by catastrophic floods.

Parker notes that “all of these regions experienced dramatic falls in population

The Imaginary Climate Crisis: How can we Change the Message? A talk by Richard Lindzen

by Prof. Lindzen, Apr 7, 2021 in WUWT/Clintel


The Irish Climate Science Forum (ICSF) in cooperation with CLINTEL hosted a lecture by the world-renowned climate scientist Richard Lindzen. The online lecture was attended by around 200 people from around the world (including a group of climate activists who disturbed the talk. The recorded talk can be viewed here.

 

Professor Lindzen kindly agreed that his written speech could be posted here at CLINTEL. It follows below.


Richard S. Lindzen, Professor Emeritus of Atmospheric Sciences, MIT

For about 33 years, many of us have been battling against climate hysteria. We have correctly noted

The exaggerated sensitivity,
The role of other processes and natural internal variability,
The inconsistency with the paleoclimate record,
The absence of evidence for increased extremes, hurricanes, etc. and so on.

We have also pointed out the very real benefits of CO2 and even of modest warming. And, as concerns government policies, we have been pretty ineffective. Indeed our efforts have done little other than to show (incorrectly) that we take the threat scenario seriously. In this talk, I want to make a tentative analysis of our failure.

Subsidence In The Bangladesh Basin

by P. Homewood, Mach 26, 2021 in NotaLotofPeopleKnowThat


Absolute sea levels are rising by about 2mm a year, yet the land is subsiding by 2.2cm a year. A small part of this is due to isostasy, but most is evidently the result of “dewatering”, what we would call water extraction. (see here)

Whatever problems farmers in Bangladesh are having, it has nothing to do with climate change.

EUROPE’S POLAR COLD TO INTENSIFY THROUGH APRIL, AS NORTH AMERICA BRACES FOR A SIMILAR FATE — GRAND SOLAR MINIMUM

by Cap Allon, April 6, 2021 in Electroverse


Land masses across the northern hemisphere are experiencing a true taste of the GRAND SOLAR MINIMUM this spring, as while brief pockets of heat have intermittently prevailed, Arctic cold has never been far away, forever-threatening to wipe out those tender early-season crops that have been “tricked” into sprouting.

Overall, Earth’s temperature is falling (the UAH for March 2021 was 0.01C BELOW 30-year baseline), but brief pockets of heat will ALWAYS occur–even during the depths of an ice age. It is actually these swings between extremes that will hasten the failure of our modern, and surprisingly fragile, food production systems — constants are workable, even if those constants are cold, it is climatic unpredictability and extreme flip-flopping that is a growers most bitter foe.

EUROPE’S POLAR COLD TO INTENSIFY THROUGH APRIL

Recently, Europe has suffered a sharp reversal of fortunes — the continent has shifted gears, going from enjoying some of its warmest March temperatures on record, to a historic blast of polar cold and snow.

The low solar activity we’ve seen over the past few years has weakened the jet stream, reverting its usual strong zonal flow to more of a wavy meridional one. At the end of March, this flow was pulling warm African air anomalously far north, which resulted in the likes of Holland, Germany, France, and Belgium registering some of their warmest March temperatures ever recorded; and now, barely a week later, this loosey-goosey jet stream has conspired to drop brutal, record-breaking Arctic air over these exact same regions.

New Study: 100-Year Flood Events Have Decreased Globally Since 1970

by  K. Richard, Apr 6, 2021 in ClimateChangeDispatch


In contrast to alarming claims about rare, 100-year flood events now occurring every few years due to global warming, scientists have determined the exact opposite is more likely true.

Not only have flood frequencies declined globally in the last 50 years, but the probability of a 100-year flood event is now so rare it has only been occurring once every 358 years on average since 1970.

According to the IPCC, there has been no clear evidence of a global-scale increase in flood magnitude or frequency in the last century (Hodgkins et al., 2017).

A new study (Slater et al., 2021) suggests that claims of flood magnitude, frequency, and probability dramatically increasing with global warming can be “misleading” if they use a stationary calculation approach instead of continually updating significant changes over time.

These scientists, using “observed annual maximum daily streamflow” records and a “nonstationary approach,” concluded there has been no obvious global-scale trend in 20-, 50-, and 100-year flood magnitude since 1970, with 100-year flood events defined as “flows of a given exceedance probability in each year.

The Sun’s climate role confirmed

by D. Whitehouse, April 6, 2021 in GWPF


“The scientific community has been unclear on the role that solar variability plays in influencing weather and climate events here on Earth. This study shows there’s reason to believe it absolutely does and why the connection may have been missed in the past.”

If you ask most climate scientists, they will tell you that the Sun’s small variability is unimportant when it comes to influencing climate. They may have to change their minds if a new line of research holds up. It seems that solar variability can drive climate variability on Earth on decadal timescales (the decadal climatic variability that Michael Mann recently ‘proved’ doesn’t exist). That’s the conclusion of a new study showing a correlation between the end of solar cycles and a switch from El Nino to La Nina conditions in the Pacific Ocean. It’s a result that could significantly improve the predictability of the largest El Nino and La Nina events, which have several global climate effects.

UAH GLOBAL TEMPERATURE DROPS BELOW 30-YEAR BASELINE — EARTH IS COOLING

by Cap Allon, April 5, 2021 in Electroverse


The Version 6.0 global average lower tropospheric temperature (LT) anomaly for March, 2021 has come in at -0.01 deg. C below the 30-year baseline, down from the February, 2021 value of +0.20 deg. C, and down substantially (approx. 0.6C deg. C) from where we were around a year ago.

A continuation of this downward plunge is highly probable over the coming months (with the odd bump along the way–climate is cyclic after all) as low solar activity and La Nina conditions persist.

According to the 15x NASA/NOAA AMSU satellites that measure every square inch of the lower troposphere (where us humans reside), planet Earth was actually warmer back in 1983:

REMINDER: We have changed the 30-year averaging period from which we compute anomalies to 1991-2020, from the old period 1981-2010. This change does not affect the temperature trends.
[www.drroyspencer.com]

In addition, the global average oceanic tropospheric temperature anomaly is -0.07 deg. C–the lowest since November 2013. Also, the tropical (20N-20S) departure from average is -0.29 deg. C–the coolest since June of 2012. While Australia, at -0.79 deg. C, is the coolest reading since August 2014.

Bottom line, the Grand Solar Minimum is intensifying — and fast.

Sunspots (a great barometer for solar activity) have remained sparse in 2021, even at a time when the next the next solar cycle (25) should be firing-up.

The Solar Minimum of cycle 24 began bottoming-out way back in late-2017, and went on to develop into the deepest minimum of the past 100+ years — and it is still proving reluctant to release its grip:

New study ties solar variability to the onset of decadal La Nina events

by C. Rotter, April 5, 2021 in NATIONAL CENTER FOR ATMOSPHERIC RESEARCH/UNIVERSITY CORPORATION FOR ATMOSPHERIC RESEARCH


A new study shows a correlation between the end of solar cycles and a switch from El Nino to La Nina conditions in the Pacific Ocean, suggesting that solar variability can drive seasonal weather variability on Earth.

If the connection outlined in the journal Earth and Space Science holds up, it could significantly improve the predictability of the largest El Nino and La Nina events, which have a number of seasonal climate effects over land. For example, the southern United States tends to be warmer and drier during a La Nina, while the northern U.S. tends to be colder and wetter.

“Energy from the Sun is the major driver of our entire Earth system and makes life on Earth possible,” said Scott McIntosh, a scientist at the National Center for Atmospheric Research (NCAR) and co-author of the paper. “Even so, the scientific community has been unclear on the role that solar variability plays in influencing weather and climate events here on Earth. This study shows there’s reason to believe it absolutely does and why the connection may have been missed in the past.”

The study was led by Robert Leamon at the University of Maryland-Baltimore County, and it is also co-authored by Daniel Marsh at NCAR. The research was funded by the National Science Foundation, which is NCAR’s sponsor, and the NASA Living With a Star program.

Arctic Sea Ice Extent Higher Than 2006

by P. Homewood, April 6, 2021 in NotaLotofPeopleKnowThat


Seventh lowest? The NSIDC would of course like you to believe that this is all part of a declining trend. In reality, since the sharp decline beginning in 2004, sea ice extent has gone up and down, but with little overall change. This year and last year, average March extent has actually been higher than in 2006.

http://ocean.dmi.dk/arctic/icecover_30y.uk.php

 

This March, extent was the 8th highest in the last 18 years, putting it around the median.

What about prior to 2004 though? Should we not be comparing this year with the 1981-2010 average?

Like it or not, and whatever the reason, the loss of summer ice in 2007 has had a direct effect on sea ice at all times of year since. Much of the sea ice is now thin, new ice, which melts more readily in summer. Consequently, winter ice takes longer to form as well.

It would probably take a climatic regime shift, such as occurred in the 1960s, for ice to return to pre 2004 levels. But the evidence shows that winter sea ice extent is currently stable.

 

Antarctic Sea Ice Grows 2 Million Sq. Km – Area As Big As Saudi Arabia. And: Hamburg Spring Arriving Later…

by P. Gosselin, March 28 in NoTricksZone


Antarctic sea ice grows 2 million square kilometers in 4 years…

It’s hard to back up the statement: Global warming is global. Some places have seen warming over the past 40 years (e.g. Arctic), but other places have not.

Antarctica definitely has not been playing along with the man-made global warming hoax. (Yes, man has caused some of the warming, but not all – and it certainly isn’t catastrophic).

Antarctic sea ice surges

Though Antarctic sea ice fell to a “record minimum” in 2017 – after having reached a “record high” in 2015 – the latest data from the National Snow and Ice Data Centershow sea ice at the South Pole has bounced back robustly since, surging some 500,000 sq km above the mean.

On March 26, 2017, Antarctic sea ice measured 3.055 million sq km. Four years later, sea ice reached 5.103 million sq km. That’s a difference of more than 2 million sq. km., which is an area the size of Saudi Arabia!

No way to ignore natural factors

So why would sea ice grow so quickly? If the ice had disappeared, many would blame it on greenhouse gases – absurd of course. And it would be just as absurd to blame the recent gain on global cooling. Obviously there is a complex array of natural factors at work – factors that climate alarmists consistently have ignored over the past decades.

A New Lockdown to “Save” the Climate

That’s what’s in store for us if Alexandria Ocasio-Cortez and the Democrats pass their radical climate plan—the Green New Deal.

It is packed with guarantees so completely irrelevant to the problem it purports to “solve” (like “free college” and incomes for everyone “unable or unwilling to work”) that even its boosters have admitted it’s not really about the climate.

The intrepid Marc Morano, author of the bestselling Politically Incorrect Guide to Climate Change, breaks down the science and the politics to expose the truth about the Green New Deal:

• The science is settled: copious evidence—and prominent defections from the “climate consensus”—make clear we are not facing a man-made climate disaster

• “Climate change” is the perfect Trojan horse for the socialist agenda of the Left

• Fossil fuels lifted the West out of poverty—but our elites now want to deny them to the world’s poor

• The Green New Deal is on a collision course with self-government and our fundamental rights

Climate change has already been “solved” multiple times over the past two decades—with highly touted international agreements—and yet it never goes away as an excuse for leftist policies that will cripple our economy, impoverish the world, and take away our freedoms.

Packed with telling statistics, damning quotations, and real science, Green Fraud is your source for all the facts you need to understand—and resist—the threat.

End of Snow? Finland Thinks Their Winter Snow Might Not Melt This Summer

by E. Worall, March 23, 2021 in WUWT


Finland thinks that piles of snow accumulated from road clearing this year are so large, some of the snow will still be frozen when winter returns.

In Finnish capital region, snow piles built up this winter may not melt during summer

FINLAND  15 MARCH 2021

THE CAPITAL REGION of Finland has received so much snow this winter that the metres-high piles hauled to designated snow dump areas may not melt during the course of the summer, reports Helsingin Sanomat.

In Uusimaa, for example, the amount of snow was 1.7 times higher than last year in January, according to Foreca.

Helsingin Sanomat on Friday wrote that the piles of snow stand almost as high as 20 metres at the dump area in Herttoniemi, eastern Helsinki. In Maununneva, a north-western neighbourhood of the city, lorries have dumped roughly 16,000 loads of snow at the dump area, revealed Tero Koppinen, a production manager at Helsinki City Construction Services (Stara).

The snow ploughed from roads forms a large structure, nicknamed by the locals as the Alps, also at the only snow dump area in Espoo, in Vanttila.

Fake Invisible Catastrophes and Threats of Doom — Patrick Moore’s outstanding new book

by Dr. J. Lehr, March 17, 2021 in CFACT


There have been dozens of good books written in the past decade telling the true stories countering the incessant lies of alarmists blaming impending environmental disasters on carbon dioxide emissions.

None have been better than the newest contribution by Patrick Moore and certainly none as up to date as this just published contribution to real science. We all know by now that Patrick co-founded Greenpeace. It was in an effort to stop underground hydrogen bomb testing and later to save whales and Harp seals. He was still studying for his degree in Ecology at the University of British Columbia (UBC). Fifteen years later when Greenpeace became a money machine in the war to scare the public with one environmental lie after another, he resigned and became their public enemy number one. The tipping point was the organization’s initiation of a campaign to ban chlorine, the most important of all 94 natural elements for both public health and medicine.

In many ways his newest book can be seen as eleven brief books teaching the important facts and research on the major environmental issues of our time. They include in addition to the finest argument against human-caused climate change, dying trees in Africa, the Great Barrier Reef, Polar Bears, Species Extinction, the Great Pacific Garbage Patch, Genetically Modified Food, Nuclear Radiation, Forest Fires, Ocean Acidification, and the faked deaths of Walruses falling from cliffs in Russia.

What sets this outstanding book apart from most is that while Moore is an academic with a Ph.D. in ecology from UBC (which he describes as the study of how all components of our world interrelate and interact), he has a somewhat unique ability to dive into the weeds on each subject and emerge with a basic understanding of each issue for the reader. While I have read a great deal on all his topics, I was amazed how much I learned, and you will be too.Fake Invisible Catastrophes and Threats of Doom -- Patrick Moore's outstanding new book

He tells us what most of us realize today, that to many if not most activists “the people are a kind of afterthought to be considered only once the perfect environmental policy has been identified, without regard for how negative the impact is on humanity”. The push to phase out all fossil fuel consumption in the next 30 years he says, “is the biggest threat to civilization in the world today.”

In this 204-page 11-chapter book, as you would imagine, its longest chapter (49 pages) Climate of Fear and Guilt, is devoted to climate change. Most readers have read numerous arguments against the well-known fraud of human caused global warming. You may not want to read another. I can tell you, however, that no one has done it better. This well illustrated chapter manages to add common sense ways to convince your friends of the absurd effort by our new administration to convince you to give up your freedoms in order to save the world. He deals with 19 separate crazy predictions laid at the feet of climate change. He skewers them all with excellent technical references. While it is worth the price of the book, it is the less well-known information in the other chapters that produce a truly outstanding book.

Greenland And Iceland Mean Winter Temperatures Continue Cooling Since Start Of The Century

by Kirye & Pierre, March 24, 2021 in NoTricksZone


The February 2021 data for Iceland and Greenland are available from the Japan Meteorological Agency (JMA), which means the latest meteorological DJF winter mean temperature can be computed.

Icelandic winters have cooled since 2001

We plotted the JMA data for three stations (the ones with sufficient data) in Iceland. Result: no warming over the past 18 winters!

Apparent Atlantic warming cycle likely an artifact of climate forcing

UNIVERSITY PARK, Pa. — Volcanic eruptions, not natural variability, were the cause of an apparent “Atlantic Multidecadal Oscillation,” a purported cycle of warming thought to have occurred on a timescale of 40 to 60 years during the pre-industrial era, according to a team of climate scientists who looked at a large array of climate modeling experiments.

The result complements the team’s previous finding that what had looked like an “AMO” occurring during the period since industrialization is instead the result of a competition between steady human-caused warming from greenhouse gases and cooling from more time-variable industrial sulphur pollution.

“It is somewhat ironic, I suppose,” said Michael E. Mann, distinguished professor of atmospheric science and director, Earth System Science Center, Penn State. “Two decades ago, we brought the AMO into the conversation, arguing that there was a long-term natural, internal climate oscillation centered in the North Atlantic based on the limited observations and simulations that were available then, and coining the term ‘AMO.’ Many other scientists ran with the concept, but now we’ve come full circle. My co-authors and I have shown that the AMO is very likely an artifact of climate change driven by human forcing in the modern era and natural forcing in pre-industrial times.”

The researchers previously showed that the apparent AMO cycle in the modern era was an artifact of industrialization-driven climate change, specifically the competition between warming over the past century from carbon pollution and an offsetting cooling factor, industrial sulphur pollution, that was strongest from the 1950s through the passage of the Clean Air Acts in the 1970s and 1980s. But they then asked, why do we still see it in pre-industrial records?

Is Climate Change Real?

by Robert Lyman,  March 23, 2021 in FriendsofScienceCalgary


Contributed by Robert Lyman © 2021 Full bio here.

Is climate change real? Journalists in Canada have had a field day with that question since it was debated at the Conservative Party policy meeting on March 20, 2021. It is the perfect question to ask if you want to boil a mind-numbingly complex set of issues into a simple question that can be used to misinform and confuse people. The proper answer to that question is another one. To what part of the climate policy conundrum are you referring?

You see, the “realness” (or truthfulness, or even importance) of climate policy depends on the answer to several questions, not one. Let’s break them down, and comment ever so briefly on the possible answers.

Is global warming occurring?

The global climate has been changing for millions of years, with temperatures rising and falling. They were as high as they are today during Roman times and the Medieval Warm Period. Since 1850, global average temperatures have risen slightly more than one degree Celsius.

We’re Not Gonna Drown! Analyses Show COASTAL SEA LEVEL RISE Is Only 1.69 mm Per Year!

by P. Gosselin, March 23, 2021 in NoTricksZone


UPDATE: Sea level rise near the coasts where people actually live is found to be 1.69 mm/yr. But when crunching the data for the entire ocean, as Willis Eschenbach has shown, a figure of just 1.52 mm/year is computed. 

Hot shot data analyst Zoe Phin at her site examines sea level rise.

There she notes, “Climate alarmists are worried that the sea level is rising too fast and flooding is coming soon. You can find many data images like this on the net:”

CLIMATE CHANGE, COVID-19, AND THE GREAT RESET

by A. MacRae, March 2021 in Elecroverse


The below treatise was sent to Canadian and American politicians and the media – but most of them won’t understand it, because they have no scientific competence and have been utterly deceived – programmed for decades by false climate scares and green energy frauds.

SUMMARY

We published in 2002 that there was NO catastrophic human-made global warming /climate change crisis, and green energy schemes were NOT green and produced little useful (dispatchable) energy. Dangerous global warming and climate change have NOT HAPPENED and green energy schemes have proved to be COSTLY, UNRELIABLE AND INEFFECTIVE. Global warming is NOT a threat, but global cooling IS dangerous. In 2002 we predicted that global cooling would start circa 2020, based on low solar activity, and that prediction is increasingly supported by the evidence.

Politicians foolishly accepted very-scary global warming falsehoods and brewed the perfect storm, crippling our energy systems with costly and unreliable green energy schemes that utterly fail due to intermittency, at a time when we will need more reliable, dispatchable energy due to increased energy demand and imminent global cooling. The good people of Australia, Britain, Germany, California and Texas have all suffered and died due to green energy failures that were PREDICTABLE AND PREDICTED.

THE GREENS’ PREDICTIVE CLIMATE AND ENERGY RECORD IS THE WORST

Twice as much carbon flowing from land to ocean than previously thought

by Institute for Basic Science, March 18, 2021 in WUWT 


Every year 600-900 million tons of carbon flow through rivers to the ocean either as particles or in dissolved form. Researchers have known for a long time that this does not represent the total amount of carbon that gets transported from the land to the ocean. But the remaining contributors mostly from coastal ecosystems, such as carbon-rich mangrove forests, and from groundwater discharge into the ocean have been notoriously difficult to measure.

A new study published in the journal Global Biogeochemical Cycles and spearheaded by Dr. Eun Young Kwon, project leader at the IBS Center for Climate Physics South Korea provides new estimates of this elusive component of the global carbon cycle. The study makes use of the existence of two stable carbon isotopes, 12C and 13C, with the latter being slightly heavier, because it has one more neutron in its nucleus. The concentration ratio between these two carbon isotopes (referred to as ?13C) provides a means to track carbon through the different components of the carbon cycle, including the atmosphere, oceans, river systems and the biosphere. Knowing the typical ?13C value of land biosphere and for coastal vegetation, one can now track how this quantity gets diluted in the oceans. “The carbon isotope values act like an invisible dye that tells us something about the source where it came from and how much got released initially” says Dr. Kwon, lead author of the study.

False Alarm: IPCC Models Say A Warming Antarctica REDUCES Sea Levels -0.8 Of A Meter By 3000

by K. Richard, March 15, 2021 in NoTricksZone


The IPCC-endorsed anthropogenic global warming (AGW) paradigm finds a warming Antarctica results in more precipitation locked up as ice on the continent. This contributes to reducing sea levels: a -1.2 mm/year−1 mitigation of sea level rise over the next 80 years.

In the 4th IPCC report, Working Group 1 (the physical science) reported that as global temperatures rise,GCMs [models] indicate increasingly positive SMB for the Antarctic Ice Sheet as a whole because of greater accumulation.” This means that by 2100 Antarctica “would contribute 0.4 to 2.0 mm yr−1 of sea level fall.” Over the next 980 years, Antarctica’s ice accumulation will reduce sea levels by nearly a full meter (-0.8 m by 3000).

Clouds From Both Sides Now

by W. Eschenbach, March 15, 2021 in WUWT


Clouds are said to be the largest uncertainty in climate models, and I can believe that. Their representation in the models is highly parameterized, each model uses different parameters as well as different values for the same parameters, and so of course, different models give very different results. Or to quote from the IPCC, the Intergovernmental Panel on Climate Change:

In many climate models, details in the representation of clouds can substantially affect the model estimates of cloud feedback and climate sensitivity. Moreover, the spread of climate sensitivity estimates among current models arises primarily from inter-model differences in cloud feedbacks. Therefore, cloud feedbacks remain the largest source of uncertainty in climate sensitivity estimates.

The question of importance is this—if the earth heats up, will clouds exacerbate the warming or will they act to reduce the warming? The general claim from mainstream climate scientists and the IPCC is that the clouds will increase the warming, viz:

All global models continue to produce a near-zero to moderately strong positive net cloud feedback.

My own theory is that clouds and other emergent climate phenomena generally act to oppose any increases in surface temperature. So me, I’d expect the opposite of what the models show. I figured that there should be a negative cloud feedback that opposes the warming.

So I thought I’d take a look at answering the question using the CERES satellite dataset. As a prologue, here’s a short exposition about measuring the effect of clouds.

Major February global temperature drop reveals the real climate control knob

by J. Bastardi, March 7, 2021 in CFACT


By now all of you know my belief ( bias) that it’s the oceans, and more so the tropical oceans, that are the biggest control knob of the weather and climate. If you really wanted to make this a controlled classroom experiment (nature is not a classroom with easy controls)  then I venture to say that the real way to know man’s influence is to have SST’s return to where they were in the 1970s, give it a couple of years for the water vapor adjustment, ( and if I am right. co2 will adjust as warmer oceans outsource it, so the outsourcing to the air will decrease) and see the difference there. And there you may be able to make an irrefutable argument for man’s contribution, Unfortunately for those who will not look at anything else,  that is likely to be quite small, but on the other hand, unlike the warming we have had which is really in the coldest driest places and more so at their coldest driest time of the year, you would likely find the lions share of what warming would be where life thrives.. As small as that has been, less than .25C of the numbers we see all the time that tell us that at. a bit over 59 degrees the planet is overheating, it is liable to be even less detectable and certainly as or more adaptable than what we seemed to have adapted to nicely here.

But the fear of course is runaway warming which is interesting since it counters Le Chateliers,  which I never hear anyone bring up, most likely because it’s a simple explanation. And a simple explanation would impact a lot of things relying on a done deal, complex explanation that the public must accept because they could never understand.

Danish Institute Data: Greenland Ice Melt Has Slowed Down Significantly Over Past Decade

by P. Gosselin, March 10, 2021 in NoTricksZone


The media and activists, among them a number of “Climate scientists”, have been declaring that Greenland ice melt has been accelerating.

Today the German Klimaschau climate news video reports, however, that this has not been the case over the recent years. All the recent talk about accelerating Greenland ice loss over the past years is false.

SMB on the rise

First a plot of Greenland’s surface mass balance SMB (blue curve below) shows that snow accumulation has occurred faster than snow and ice have melted over the past 35 years:

Though the annual SMB values declined from 1985 to 2012, the trend has rebounded since.

Shock News–China 5-Year Plan Will Increase Emissions

by P. Homewood, March 6, 2021 in NotaLotofPeopleKnowThat


China has set out an economic blueprint for the next five years that could lead to a strong rise in greenhouse gas emissions if further action is not taken to meet the country’s long-term goals.

The 14th five-year plan, published in Beijing on Friday, gave few details on how the world’s biggest emitter would meet its target of reaching net zero emissions by 2060, set out by President Xi Jinping last year, and of ensuring that carbon dioxide output peaks before 2030.

China will reduce its “emissions intensity” – the amount of CO2 produced per unit of GDP – by 18% over the period 2021 to 2025, but this target is in line with previous trends, and could lead to emissions continuing to increase by 1% a year or more. Non-fossil fuel energy is targeted to make up 20% of China’s energy mix, leaving plenty of room for further expansion of the country’s coal industry.

Swithin Lui, of the Climate Action Tracker and NewClimate Institute, said: “[This is] underwhelming and shows little sign of a concerted switch away from a future coal lock-in. There is little sign of the change needed [to meet net zero].”

Zhang Shuwei, chief economist at Draworld Environment Research Centre, said: “As the first five-year plan after China committed to reach carbon neutrality by 2060, the 14th five-year plan was expected to demonstrate strong climate ambition. However, the draft plan presented does not seem to meet the expectations. The international community expected China’s climate policy to ‘jump’, but in reality it is still crawling.”

Unusually, this five-year plan did not set out GDP targets for the whole five-year period, but allowed for annual targets, with the first for this year a target of 6% growth. The Centre for Research on Energy and Clean Air said that coupled with the emissions intensity target, this could allow the growth rate of China’s emissions to speed up even further, rather than slow down, as is needed.
