To The Horror Of Global Warming Alarmists,
Global Cooling Is Here
Around 1250 A.D., historical records show, ice packs began showing
up farther south in the North Atlantic. Glaciers also began expanding on
Greenland, soon to threaten Norse settlements on the island. From 1275 to 1300
A.D., glaciers began expanding more broadly, according to radiocarbon dating of
plants killed by the glacier growth. The period known today as the Little Ice
Age was just starting to poke through.
Summers began cooling in Northern Europe after 1300 A.D.,
negatively impacting growing seasons, as reflected in the Great Famine of 1315
to 1317. Expanding glaciers and ice cover spreading across Greenland began
driving the Norse settlers out. The last, surviving, written records of the
Norse Greenland settlements, which had persisted for centuries, concern a
marriage in 1408 A.D. in the church of Hvalsey, today the best preserved Norse
ruin.
Colder winters began regularly freezing rivers and canals in Great
Britain, the Netherlands and Northern France, with both the Thames in London
and the Seine in Paris frozen solid annually. The first River Thames Frost Fair
was held in 1607. In 1607-1608, early European settlers in North America
reported ice persisting on Lake Superior until June. In January, 1658, a
Swedish army marched across the ice to invade Copenhagen. By the end of the
17th century, famines had spread from northern France, across Norway and
Sweden, to Finland and Estonia.
Reflecting its global scope, evidence of the Little Ice Age
appears in the Southern Hemisphere as well. Sediment cores from Lake Malawi in
southern Africa show colder weather from 1570 to 1820. A 3,000 year temperature
reconstruction based on varying rates of stalagmite growth in a cave in South
Africa also indicates a colder period from 1500 to 1800. A 1997 study comparing
West Antarctic ice cores with the results of the Greenland Ice Sheet Project
Two (GISP2) indicate a global Little Ice Age affecting the two ice sheets in
tandem.
The Siple Dome, an ice dome roughly 100 km long and 100 km wide,
about 100 km east of the Siple Coast of Antartica, also reflects effects of the
Little Ice Age synchronously with the GISP2 record, as do sediment cores from
the Bransfield Basin of the Antarctic Peninsula. Oxygen/isotope analysis from
the Pacific Islands indicates a 1.5 degree Celsius temperature decline between
1270 and 1475 A.D.
The Franz Josef glacier on the west side of the Southern Alps of
New Zealand advanced sharply during the period of the Little Ice Age, actually
invading a rain forest at its maximum extent in the early 1700s. The Mueller
glacier on the east side of New Zealand’s Southern Alps expanded to its maximum
extent at roughly the same time.
Ice cores from the Andeas mountains in South America
show a colder period from 1600 to 1800. Tree ring data from Patagonia in South
America show cold periods from 1270 to 1380 and from 1520 to 1670. Spanish
explorers noted the expansion of the San Rafael Glacier in Chile from 1675 to
1766, which continued into the 19th century.
The height of the Little Ice Age is generally dated as 1650 to
1850 A.D. The American Revolutionary Army under General George Washington
shivered at Valley Forge in the winter of 1777-78, and New York harbor was
frozen in the winter of 1780. Historic snowstorms struck Lisbon, Portugal in
1665, 1744 and 1886. Glaciers in Glacier National Park in Montana advanced
until the late 18th or early 19th centuries. The last River Thames Frost Fair
was held in 1814. The Little Ice Age phased out during the middle to late 19th
century.
The Little Ice Age, following the historically warm temperatures
of the Medieval Warm Period, which lasted from about AD 950 to 1250, has been
attributed to natural cycles in solar activity, particularly sunspots. A period
of sharply lower sunspot activity known as the Wolf Minimum began in 1280 and
persisted for 70 years until 1350. That was followed by a period of even lower
sunspot activity that lasted 90 years from 1460 to 1550 known as the Sporer
Minimum. During the period 1645 to 1715, the low point of the Little Ice Age,
the number of sunspots declined to zero for the entire time. This is known as
the Maunder Minimum, named after English astronomer Walter Maunder. That was
followed by the Dalton Minimum from 1790 to 1830, another period of well below
normal sunspot activity.
The increase in global temperatures since the late 19th century
just reflects the end of the Little Ice Age. The global temperature trends
since then have followed not rising CO2 trends but the ocean temperature cycles
of the Pacific Decadal Oscillation (PDO) and the Atlantic Multidecadal
Oscillation (AMO). Every 20 to 30 years, the much colder water near the bottom
of the oceans cycles up to the top, where it has a slight cooling effect on
global temperatures until the sun warms that water. That warmed water then
contributes to slightly warmer global temperatures, until the next churning
cycle.
Those ocean temperature cycles, and the continued recovery from
the Little Ice Age, are primarily why global temperatures rose from 1915 until
1945, when CO2 emissions were much lower than in recent years. The change to a
cold ocean temperature cycle, primarily the PDO, is the main reason that global
temperatures declined from 1945 until the late 1970s, despite the soaring CO2
emissions during that time from the postwar industrialization spreading across
the globe.
The 20 to 30 year ocean temperature cycles turned back
to warm from the late 1970s until the late 1990s, which is the primary reason
that global temperatures warmed during this period. But that warming ended 15
years ago, and global temperatures have stopped increasing since then, if not
actually cooled, even though global CO2 emissions have soared over this period.
As The Economist magazine reported in March, “The
world added roughly 100 billion tonnes of carbon to the atmosphere between 2000
and 2010. That is about a quarter of all the CO2 put there by humanity since
1750.” Yet, still no warming during that time. That is because the CO2
greenhouse effect is weak and marginal compared to natural causes of global
temperature changes.
At first the current stall out of global warming was due
to the ocean cycles turning back to cold. But something much more ominous has
developed over this period. Sunspots run in 11 year short term cycles, with
longer cyclical trends of 90 and even 200 years. The number of sunspots
declined substantially in the last 11 year cycle, after flattening out over the
previous 20 years. But in the current cycle, sunspot activity has collapsed.
NASA’s Science News report for January 8, 2013 states,
“Indeed, the sun could be on the threshold of a mini-Maunder event
right now. Ongoing Solar Cycle 24 [the current short term 11 year cycle] is the
weakest in more than 50 years. Moreover, there is (controversial) evidence of a
long-term weakening trend in the magnetic field strength of sunspots. Matt Penn
and William Livingston of the National Solar Observatory predict that by the
time Solar Cycle 25 arrives, magnetic fields on the sun will be so weak that
few if any sunspots will be formed. Independent lines of research involving
helioseismology and surface polar fields tend to support their conclusion.”
That is even more significant because NASA’s climate science has
been controlled for years by global warming hysteric James Hansen, who recently
announced his retirement.
But this same concern is increasingly being echoed
worldwide. The Voice of Russia reported on
April 22, 2013,
“Global warming which has been the subject of so many discussions
in recent years, may give way to global cooling. According to scientists from
the Pulkovo Observatory in St.Petersburg, solar activity is waning, so the
average yearly temperature will begin to decline as well. Scientists from
Britain and the US chime in saying that forecasts for global cooling are far
from groundless.”
That report quoted Yuri Nagovitsyn of the Pulkovo
Observatory saying, “Evidently, solar activity is on the decrease. The 11-year
cycle doesn’t bring about considerable climate change – only 1-2%. The impact
of the 200-year cycle is greater – up to 50%. In this respect, we could be in
for a cooling period that lasts 200-250 years.” In other words, another Little
Ice Age.
The German Herald reported on March 31, 2013,
The German Herald reported on March 31, 2013,
“German meteorologists say that the start of 2013 is now the
coldest in 208 years – and now German media has quoted Russian scientist Dr
Habibullo Abdussamatov from the St. Petersburg Pulkovo Astronomical Observatory
[saying this] is proof as he said earlier that we are heading for a “Mini Ice
Age.” Talking to German media the scientist who first made his prediction in
2005 said that after studying sunspots and their relationship with climate
change on Earth, we are now on an ‘unavoidable advance towards a deep temperature
drop.’”
Faith in Global Warming is collapsing in formerly staunch Europe
following increasingly severe winters which have now started continuing into
spring. Christopher Booker explained in The Sunday Telegraph on April 27, 2013,
“Here in Britain, where we had our fifth freezing winter in a row,
the Central England Temperature record – according to an expert analysis on the
US science blog Watts Up With That – shows that in this century, average winter
temperatures have dropped by 1.45C, more than twice as much as their rise
between 1850 and 1999, and twice as much as the entire net rise in global
temperatures recorded in the 20th century.”
A news report from India (The Hindu April
22, 2013) stated, “March in Russia saw the harshest frosts in 50 years, with
temperatures dropping to –25° Celsius in central parts of the country and –45°
in the north. It was the coldest spring month in Moscow in half a
century….Weathermen say spring is a full month behind schedule in Russia.” The
news report summarized,
“Russia is famous for its biting frosts but this year, abnormally
icy weather also hit much of Europe, the United States, China and India. Record
snowfalls brought Kiev, capital of Ukraine, to a standstill for several days in
late March, closed roads across many parts of Britain, buried thousands of
sheep beneath six-metre deep snowdrifts in Northern Ireland, and left more than
1,000,000 homes without electricity in Poland. British authorities said March
was the second coldest in its records dating back to 1910. China experienced
the severest winter weather in 30 years and New Delhi in January recorded the
lowest temperature in 44 years.”
Booker adds, “Last week it was reported that 3,318 places in the
USA had recorded their lowest temperatures for this time of year since records
began. Similar record cold was experienced by places in every province of
Canada. So cold has the Russian winter been that Moscow had its deepest
snowfall in 134 years of observations.”
Britain’s Met Office, an international cheerleading headquarters
for global warming hysteria, did concede last December that there would be no
further warming at least through 2017, which would make 20 years with no global
warming. That reflects grudging recognition of the newly developing trends. But
that reflects as well growing divergence between the reality of real world
temperatures and the projections of the climate models at the foundation of the
global warming alarmism of the UN’s Intergovernmental Panel on Climate Change
(IPCC). Since those models have never been validated, they are not science at
this point, but just made up fantasies. That is why, “In the 12 years to 2011,
11 out of 12 [global temperature]forecasts [of the Met Office] were too high —
and… none were colder than [resulted],” as BBC climate correspondent Paul
Hudson wrote in January.
Global warming was never going to be the problem that the
Lysenkoists who have brought down western science made it out to be. Human
emissions of CO2 are only 4 to 5% of total global emissions, counting natural
causes. Much was made of the total atmospheric concentration of CO2 exceeding
400 parts per million. But if you asked the daffy NBC correspondent who
hysterically reported on that what portion of the atmosphere 400 parts per
million is, she transparently wouldn’t be able to tell you. One percent of the
atmosphere would be 10,000 parts per million. The atmospheric concentrations of
CO2 deep in the geologic past were much, much greater than today, yet life
survived, and we have no record of any of the catastrophes the hysterics have
claimed. Maybe that is because the temperature impact of increased
concentrations of CO2 declines logarithmically. That means there is a natural
limit to how much increased CO2 can effectively warm the planet, which would be
well before any of the supposed climate catastrophes the warming hysterics have
tried to use to shut down capitalist prosperity.
Yet, just last week, there was Washington Post columnist Eugene Robinson telling
us, by way of attempting to tutor Rep. Lamar Smith (R-TX), Chairman of the
House Committee on Science, Space and Technology, “For the record, and for the
umpteenth time, there is no ‘great amount of uncertainty’ about whether the
planet is warming and why.” If you can read, and you have gotten this far in my
column, you know why Robinson’s ignorance is just anotherWashington Post abuse of the First Amendment. Mr.
Robinson, let me introduce you to the British Met Office, stalwart of Global
Warming “science,” such as it is, which has already publicly confessed that we
are already three quarters through 20 years of No Global Warming!
Booker could have been writing about Robinson when he
concluded his Sunday Telegraph commentary
by writing, “Has there ever in history been such an almighty disconnect between
observable reality and the delusions of a political class that is quite
impervious to any rational discussion?”
But there is a
fundamental problem with the temperature records from this contentious period,
when climate science crashed into political science. The land based records,
which have been under the control of global warming alarmists at the British
Met Office and the Hadley Centre Climate Research Unit, and at NASA’s Goddard
Institute for Space Studies and the National Oceanic and Atmospheric
Administration (NOAA) in the U.S., show much more warming during this period
than the incorruptible satellite atmosphere temperature records. Those
satellite records have been further confirmed by atmospheric weather balloons.
But the land based records can be subject to tampering and falsification.
