According to the latest October report from the National Snow and Ice Data Center (NSIDC), the ice locked at Earth’s poles is, overall, GROWING.
Both NOAA and NASA appear to agree, if you read between the lines, with NOAA saying we’re entering a ‘full-blown’ Grand Solar Minimum in the late-2020s, and NASA seeing this upcoming solar cycle (25) as “the weakest of the past 200 years”, with the agency correlating previous solar shutdowns to prolonged periods of global cooling here.
Furthermore, we can’t ignore the slew of new scientific papers stating the immense impact The Beaufort Gyre could have on the Gulf Stream, and therefore the climate overall.
An independent candidate for the rural seat of Hill (SW Cairns) in October’s state election has harshly criticised a 2008 amendment to the Great Barrier Reef Marine Park Act of 1975 that gives “wrongologists an escape clause for damage done to farmers by their questionable expertise and advice to government”.
Peter Campion of Tolga, a retired fireman, is a long-term climate change sceptic and energy realist who has been a regular contributor to the Cairns Post’s ‘Letters to the Editor’ column. Mr Campion is standing for Hill against the Katter Party’s Shane Knuth.
“The GPRMPA Act came about due to concerns for the Great Barrier Reef, which initially stemmed from early Reef tourism operators’ misunderstandings of natural reef systems and cycles – especially relating to the ‘gardeners of the Reef’, the Crown of Thorns starfish,” he said.
“The GBRMPA Act had been in operation for 33 years before Reef researchers felt the need to have an escape clause inserted.
“To me, that suggests that by 2008 they had realised there was a fair chance they were wrong.”
The amendment that has drawn Mr Campion’s scorn is in the Great Barrier Reef Marine Park and Other Legislation Amendment Act 2008, which inserts a “precautionary principle” clause.
“The amendment describes the precautionary principle as ‘… the principle that lack of full scientific certainty should not be used as a reason for postponing a measure to prevent degradation of the environment where there are threats of serious or irreversible environmental damage.’”, Mr Campion said.
“On the basis of this blatantly ridiculous ‘precautionary principle’ all farms , industries, towns, sewage systems, and roads should be closed as they all represent a threat to the environment.
“A better precautionary principle would be the proper Popperian scientific method that automatically assumes all science is only correct until such time as it is proved that it is not – which happens far more often than you’d think.
“It is just horrific to think that these scientists, who completely failed to produce their proof to the recent federal Senate inquiry into the Palaszczuk government’s anti-farmer reef regulations, suspected 12 years ago that their work might not be reliable. Why else would they lobby for an escape clause to give cover for their own malfeasance?” he said.
The scientists at the focus of Mr Campion’s anger, Ian Chubb, Geoff Garrett, and Ove Hoegh-Gulberg, took to the far-left website The Guardian to attack the Senate inquiry as a form of defence of their research. Notably this is the research that Professor Peter Ridd was sacked from JCU for suggesting might be unreliable.
Mr Campion noted, “In their own article they still had to admit that ‘little more than 3% of the coral’ may be negatively affected by water quality issues. That means 97 per cent of the Reef is unaffected, but they still want to impose draconian controls on our food producers.
“This is an outrage. These individuals, and their institutions, are unworthy of any further support from taxpayers and the Palaszczuk government’s anti-farmer Reef regulations must be repealed immediately.”

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 the Consulate at Bergen, Norway.
Reports from fishermen, seal hunters and explorers 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 as far north as 81 degrees 29 minutes.
Soundings to a depth of 3,100 metres 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.
Within a few years it is predicted that due to the ice melt the sea will rise and make most coast cities uninhabitable.
SORRY I neglected to mention that this report was from November 2, 1922, as reported by the AP and published in The Washington Post 98 years ago.
Today climate change scientist seem to think it was caused by the Model T Ford emissions or possibly horse and cattle carbon farts.
Heat waves in Australia are nothing new and official records show it was hotter in 1896
What we today call official records started in 1910. If we think this summer has been hot how about a 24-DAY heatwave on Australia’s east coast in January 1896 that saw temperatures climb to 49 degrees and killed 437 people.
The maximum temperature was above 38.9C for over three weeks!
In January 1896 a savage blast “like a furnace” stretched across Australia from east to west and lasted for weeks. The death toll reached 437 people in the eastern states. Newspaper reports showed that in Bourke the heat approached 120°F (48.9°C) on three days. The maximum at or above 102 degrees F (38.9°C) for 24 days straight. By Tuesday Jan 14, people were reported falling dead in the streets.
Unable to sleep, people in Brewarrina walked the streets at night for hours, the thermometer recording 109F at midnight. Overnight, the temperature did not fall below 103°F.
On Jan 18 in Wilcannia, five deaths were recorded in one day, the hospitals were overcrowded and reports said that “more deaths are hourly expected”.
By January 24, in Bourke, many businesses had shut down (almost everything bar the hotels). Panic stricken Australians were fleeing to the hills in climate refugee trains.
As reported at the time, the government felt the situation was so serious that to save lives and ease the suffering of its citizens they added cheaper train services.

Letter to the Editor
The cauldron of discontent that is the climate change debate alternates between simmer and boil over, depending on what new ingredients are tossed in. The combination of drought, water shortages and bushfires all meant that the cauldron was boiling most of the time and the media was starting to run out of superlatives to describe the situation.
“Crisis” and “catastrophic” have been used to the point that they have almost become meaningless and occasionally apocalyptical.
“Outrage”has also become popular. How dare the Prime Minister allow this to happen?
Around the country groups are calling for “immediate” or “instant” action. Doing his bit to stir the pot is the smug figure of Opposition Leader Anthony Albanese.
So I think the time is right to introduce a new adjective, “hysteria”.
Greta Thumberg gave a master class in theatrically contrived hysteria at the UN.
Some of the people in the latest hysterical outburst are not in the mould of regular rent-a-crowd uni students. Among the Extinction Rebellion activists were middle aged and senior citizens.
As a senior citizen myself, I didn’t know whether to laugh or cry at their antics.
Hysteria means “emotional excess” or frenzy, irrationality, panic and loss of control, and that really concerns me.
Normally steady sane people are being swept along by the tide of professional activists whose only interest is destabilisation for their own aims under the smokescreen of climate change.
I think it’s time to sit down and take a “Bex”.

Is the directed energy weapon used to make way for an infrastructure of “smart cities” in Australia?
More than 1000 homes destroyed by wildfire

“Our fiber lasers operate with an efficiency that generates less heat and exists in a smaller housing allowing easier integration into various defense platforms. Our ALADIN laser has been operating in the field for two years without the need for realignment, proving both the deadliness and the reliability of our solutions. ”
– Dr. Rob Afzal, Senior Researcher, Sensors and Laser Systems
A theoretical, and entirely legitimate, question arises when we seek to perceive the truth among the scraps of information that we receive every day from the traditional media: is the directed energy weapon secretly used to make room for “smart cities” infrastructure in Australia? A directed energy weapon emits energy in a desired direction without the need for a projectile. It transfers energy to a target for the desired effect. The desired effects on humans may or may not be lethal.
In addition to its use on people or as a potential missile defense, directed energy technology has also been shown to stop or disable moving cars, drones, jet skis and electronic devices such as cell phones. An electrolaser allows (thanks to the laser) that the blooming occurs (forming a channel / path of ionized air of conductor), then sends a powerful electric current through the channel / path of plasma formed in the direction of the target, much like lightning. It works like a giant version of the Taser or a high-energy electric pulse pistol over a long distance.
“Now is the time to send directed energy weapons to the battlefield. The Army recognizes the need for directed energy lasers as part of its modernization plan. It is no longer a research or demonstration effort. It is a strategic combat capability, and we are on track to get it into the hands of the soldiers. ”
– Lieutenant-General L. Neil Thurgood, Director of “Hypersonics, Directed Energy, Space and Rapid Acquisition”
On December 11, 2019, Julie Kern wrote on the Futura-Sciences site: “The fires in Australia do not seem to be ending. It has been almost five months since the beginning of August that the country of kangaroos burns everywhere. The regions of New South Wales and Queensland are the most affected. More than three million hectares have been devastated by the flames in these two regions. Currently, 87 homes are still active covering a perimeter of more than ten kilometers. They are essentially bush fires which progress quickly and produce a lot of smoke which suffocates cities like Sydney. The fires also damaged precious ecosystems that house endangered animals, and more than 684 homes were consumed by the flames. Despite the emergency, Australian Prime Minister Scott Morrison has not declared a climate emergency in his country. ”
On December 22, 2019, the Sky News reported the Prime Minister’s words that there were “many other factors” than the climate change responsible for the fires that killed at least nine people.
“There is no argument, in my opinion, or from the point of view of the government, and any government in the country, about the links between the broader issues of global climate change and weather events around the world – but I I’m sure people would also recognize that direct connection to a single fire is not a credible suggestion. ”
The “official” news continues to say that the fires were caused by high heat and drought due to climate change and high winds. According to these sources, the earth has become so hot that the trees and grass have caught fire or is so dry that fires have spread over the grass and passed from one house to another even if the grass and brush between the burned houses was still green. For too hot soil, it should be at least 172 degrees C. (341.6 F.) as this is the temperature at which the hay burns (which is drier than the grass) and between 190 and 260 degrees Celsius (374 to 500 degrees F) for wood depending on the type and condition of it. In addition, warmer weather should bring more rain as more water is drawn from the ocean, creating clouds of rain. In the Contracts for Weather Control document, you can read at the bottom of page 13 how HAARP disperses storms and can create winds up to 70 mph.
The order of the day is to convince people that global warming is real in order to gain their acceptance to lose their rights and to shape their lifestyles into a single dictatorial world government.
Although the fire map is not evidence of the use of directed energy weapons, it is strange that almost the entire continent burns at the same time, around the same time that California burns. Australia has had bush fires before, but not nearly as much and at the same time. Mainstream media continues to blame climate change for the hot, dry conditions. As noted above, it must be at least 374 to 500 degrees F for the wood to start burning. (Chemtrail Planet)

Planning for 5G “smart cities” in Australia
High view to Hyde Park, Sydney at night Driven by cutting-edge technology and infrastructure, smart cities have progressed, embraced a future concept and are now becoming a reality, with the Australian government initiating a new plan to “transform cities and regional sites ”. The “smart city plan” will include new mechanisms to monitor and control society through technology, including intelligent management of infrastructure functions, ground and air sensors, surveillance with facial recognition, “Sustainable projects” and more.
Many systems are already there, and over the next decade, regions of the country are expected to interconnect to create a national 5G smart grid controlled by advanced biometric technologies. By 2021, the number of devices connected to the Internet of Things (IoT) is expected to double, and one major development that is already happening around the world to respond to this increase is the “smart city revolution”.
Using information and communication technologies, a “smart city” aims to provide personalized and intelligent services to residents, businesses and, most importantly, authorities. A smart city is officially defined by international standards as:
“Efficient integration of physical, digital and human systems into the built environment to provide a sustainable, prosperous and inclusive future for its citizens. “(ISO PAS 180, 2014).
A smart city uses data from IoT devices and sensors, widely used by artificial intelligence systems, to improve the city’s service experience, using “smart management” of resources to mitigate problems such as congestion, crime and pollution. Common themes found in smart city designs include: CCTV cameras with facial recognition capabilities, “smart lights” and LED sensors, pedestrian trackers, city movement monitoring systems and “ environmental analyzes ”to understand air quality such as dust, pollution and temperature.
The technology to create this type of smart city is already available and used around the world, including bins that compost, street lights that darken when not needed and light up when pedestrians pass, moment sensors and apps advising live data and much more.
Thermometers bursting in 18th century
Adelaide historical records shatter climate cultists
The hottest day was not in 2019, but 1828 at a blistering 53.9 °C. Back before man-made climate change was frying Australia, when CO2 was around 300ppm, the continent savoured an ideal pre-industrial climate…. RIGHT? This is the kind of climate we are spending $10bn per annum to get back to … Right again? We are told today’s climate has more records and more extremes than times gone by, but the few records we have from the early 1800s are eye-popping.
Things were not just hotter, but so wildly hot it burst thermometers. The earliest temperature records we have show that Australia was a land of shocking heatwaves and droughts, except for when it was bitterly cold or raging in flood. In other words, nothing has changed, except possibly things might not be quite so hot now!
Silliggy (Lance Pidgeon) has been researching records from early explorers and from newspapers. What he’s uncovered is fascinating! It’s as if history is being erased! For all that we hear about recent record-breaking climate extremes, records that are equally extreme, and sometimes even more so, are ignored. In January 1896 a savage blast “like a furnace” stretched across Australia from east to west and lasted for weeks. The death toll reached 437 people in the eastern states. Newspaper reports showed that in Bourke the heat approached 120°F (48.9°C) on three days.

The maximum at or above 102 degrees F (38.9°C) for 24 days straight! Use the several links below to read the news reports at the time for yourself ..

http://trove.nla.gov.au/ndp/del/article/79288908?zoomLevel=5>inAs reported at the time, the government felt the situation was so serious that to save lives and ease the suffering of its citizens they added cheaper train services. What I found most interesting about this was the skill, dedication and length of meteorological data taken in the 1800s. When our climate is “the most important moral challenge” why is it there is so little interest in our longest and oldest data?
Who knew that one of the most meticulous and detailed temperature records in the world from the 1800s comes from Adelaide, largely thanks to Sir Charles Todd.
The West Terrace site in Adelaide was one of the best in the world at the time, and provides accurate historic temperatures from “Australia’s first permanent weather bureau at Adelaide in 1856”
Rainfall records even appear to go as far back as 1839. Lance Pidgeon went delving into the National Archives and was surprised at what he found.
The media are in overdrive, making out that “the extreme heat is the new normal” in Australia. You can’t blame those high records on man-made global warming!

Did government agents light some of the multitude of fires?
The recent bush fires in New South Wales were deliberately lit in order to promote the idea that ‘climate change’ is the threat which caused them and that Australia therefore needs to enact policy to deal with ‘climate change’ so as to prevent further devastation.
It’s irrelevant who was caught lighting the fires, even if they were youths. These are third party intermediaries used for plausible deniability. The Australian government is behind the deliberate lighting of these fires.
Look at the flare up in the Jewish-controlled media linking the fires to ‘climate change’. It’s obvious. First, schoolchildren in Australia protested about ‘climate change’ and that fell flat. Then Greta Thunberg travelled to the United Nations in a yacht to protest about ‘climate change’ and that fell flat because nobody wants to be lectured by a sixteen year old girl being fed a bunch of lines by adult propagandists.
So, the people who want policy to be enacted in Australia regarding ‘climate change’ said to each other, “They ignored the schoolchildren. They even ignored Greta! Let’s give them something they can’t ignore.”
Australian citizens voted Liberal over Labor at the last federal election because they didn’t want the action on ‘climate change’ that Labor was promoting. The majority think that ‘carbon dioxide-driven climate change’ is a fraud, like I do. (Carbon dioxide exists in the earth’s atmosphere at less than 400 parts per million, which is less than 1 part per 2,500, so it doesn’t influence the climate to any appreciable extent.) Australians voted the Liberal Party into federal government at the last federal election earlier this year because it’s the lesser of two very bad evils. Scott Morrison is an appalling Prime Minister but Bill Shorten would have been twice as bad.
The Liberal Party pretends to be opposed to action on ‘climate change’ when it actually supports it and wants it. It knows that the majority of Australian citizens don’t trust the ‘climate change’ agenda, so it’s pretended to adopt the same mistrust in order to win their support. Therefore, if it’s going to be successful enacting policy on ‘climate change’, it needs to resort to indirect methods of lobbying the citizenry, such as deliberately lighting bush fires and then relying on the media to push the narrative that ‘climate change’ is the reason for the fires. The Liberal Party wants to end up in a position in which it is seen as having no choice but to enact policy to deal with ‘climate change’, since ‘climate change’ has become universally recognised as a threat by the citizenry due to high-impact incidents like the bush fires in New South Wales.
The Liberal Party supports action on ‘climate change’ because its allegiance is to the Rothschilds-led synagogue of Satan that needs action on ‘climate change’ in countries around the world in order to provide an excuse for establishing world government ruling over various unions around the world like the European Union, the African Union and the South American Union. There is a planned Asia Pacific Union including China, India and Australia, as well as other Asian countries. There is also a planned North American Union including the United States of America, Canada and Mexico. ‘Climate change’ is the fabricated threat to the entire world which the synagogue of Satan will claim, can only be properly addressed with common policies and methodologies enforced and implemented by world government.
The Rothschilds-led synagogue of Satan has been pushing the fraudulent ‘climate change’ agenda in earnest since 2008 and it’s had this issue on the boil for the past three decades and longer.

The new EU Agriculture Commissioner has publicly stated that Europe loses 1,000 farms per day. He acknowledged that the EU is losing 400,000 farms per year. However, crop and livestock production in Europe is projected to decline and maybe completely abandoned Europe’s southern and Mediterranean regions due to the increased negative impacts of climate change, according to a European Environment Agency study.
The study says that adapting to climate change must be made a top priority for the European Union’s agriculture sector if it is to improve resilience to extreme events like droughts, heatwaves, and floods. But the obsession with Climate Change in Europe which is destroying its economy and now its ability to even grow food many are concerned will lead to starvation once again as was the case in Ireland because of the British Corn Laws which prohibited the importation of grain from America.
The nonsense of Climate Change seems to be poised to accomplish what it is designed to do – reduce the population. The question that needs to be answered is: Whose grandchildren are we trying to prevent from being born? Those who do not believe in Climate Change created by Humans? Certainly not the promoters or politicians. So it must be the rest of us they want to starve.
It certainly appears that perhaps this is the backdrop as to why we may see a rise in agricultural prices into 2025 and our computer is showing this should be a cost-push inflationary wave.

AS THE LATEST U.N. climate summit begins in New York, a new, high-level global network of 500 prominent climate scientists and professionals has submitted a declaration that there is no “climate emergency”.
The group has sent a European Climate Declaration with a registered letter to António Guterres, Secretary-General of the United Nations.
Professor Guus Berkhout of The Netherlands, who organized the Declaration, said: “So popular is the Declaration with scientists and researchers worldwide that signatories are flooding in not only from within Europe but also from other countries such as the United States and Canada, Australia and New Zealand.”
The group’s letter warns the U.N. that “the general-circulation models of climate on which international policy is at present founded are unfit for their purpose”.
The Declaration adds that the models, which have predicted far more warming than they should (see diagram), “are not remotely plausible as policy tools”, in that “they … exaggerate the effect of greenhouse gases such as CO2” and “ignore the fact that enriching the atmosphere with CO2 is beneficial”.
The “climate emergency” that never was: Global warming predicted by climate models (purple and red cursors) is three times warming expected on the basis of officially-estimated manmade influences on climate (orange cursor) and four times observed warming (green cursor).
The letter invites the Secretary-General to work with the global network to organize a constructive, high-level meeting between world-class scientists on both sides of the climate debate in early 2020.

If you want to live among the trees then expect more destruction
Thousands of hectares of wallum scrub and once open forest in the Sunshine and Gold Coast hinterlands and seaside suburbs were razed this week in what was a preventable inferno.
Many homes and the historic Binna Burra Lodge in the Gold Coast hinterland were lost to wildfire. Where were the fire breaks? Where was the back burning in the days or weeks before?
The Labor state government’s poor management record of forest and national park reserves across the state will see more of these dangerous conflagrations especially during long periods of dry weather.
The Deputy Premier, comrade Jackie Trad, a Green tragic, was quick to blame ‘climate change’ but she is bereft of any intelligence to know the widespread hot ember storm was caused by her UN-inspired polices of no firebreaks, no heavy machinery, no hazard reduction burning and no cattle grazing on any land.
These fires simply are a repeat of the widespread destructive wildfires which burnt out nearly half a million hectares north of Bundaberg in 2018.
Until this state is rid of urban politicians who have no understanding of the garden bed next door let alone the vast uninhabited areas of Queensland we will continue to witness devastating environmental damage never before seen in the history of the ‘sunshine state.’
In the ample dramatic ‘never let the facts get in the way of a good story’ footage, televisions across the nation flashed bulletins of wildfires and ember storms which caused spot fires some 300 or more metres distant.
Climate change is the culprit, say the hopeless Greens, but the climate changes every day so this stupidity carries no water. The state is in drought, a continuous cycle of weather patterns caused by differing solar activity.
Wet sclerophyll or rainforest encroaches on open forest, and a succession of wet years followed by a drought can allow so-called rain forest to burn if sufficient detritus is on the forest floor.
Witness the wanton waste of taxpayer money near Lockhart River Aboriginal community in the electorate of the state member of parliament Cynthia Lui from Yam Island.
A fire, presumably lit by Aborigines, which got into the Iron Range ‘rain forest’ is being water bombed by aircraft. This area of Cape York Peninsula has an annual rainfall during the wet season of more than a metre and a half.
Meanwhile bushfire-fighting practices in the south east corner under the direction of the urban fire department were doomed to fail before they began.
Where were the experienced incident control officers from northern Rural Fire Services?
Thee urban brigades with well-paid staff won’t allow battle toughened rural firies near the control base. They want unpaid volunteers at the fire front.
More importantly nowhere in urbanised TV bulletins was a bulldozer or grader to be seen or were any worthwhile fire breaks.
In hinterland grazing country, when composted, dry kikuyu pastures and cow pats burn the fire can only be contained by graded firebreaks.
Reports of nearly metre-high piles of dry litter on forest floors interwoven with a lantana jungle are a result of an absence of hazard reduction burning over many years.
Because the national park service and the Labor state government generally won’t allow firebreaks to be constructed in its millions of hectares of wasteful parks estates, then without hazard reduction burns we have just experienced the result.
The Liberal Party fares little better having lost its way decades ago.
Time to take back the reins people(sheeple?).

The war on hydro-carbon fuels will have no measurable effect on global temperatures. Nor will carbon taxes, carbon offsets or subsidies for wind turbines or solar panels. There are climate controllers far bigger than human CO2 at work.
No place on Earth lives in the mythical average global temperature. Earth’s temperature dances to cyclic rhythms every hour, every day, every month, every season, every year, and to every beat of the sun-spot and glacial cycles.
The daily cycle of Earth’s rotation causes continual changes in radiant energy received by and transmitted from every spot on Earth. It produces the cold at dawn and the afternoon warmth.
Superimposed on the daily solar cycle is the monthly lunar cycle, driven by the orbit of the Moon around the Earth. These two cycles interact to produce variations in atmospheric pressure, and tides and currents in the oceans and the atmosphere. These are the short-term weather makers.
The yearly seasonal cycle is caused as the tilted axis of Earth’s rotation affects the intensity of solar energy received by each hemisphere. This produces spring, summer, autumn and winter for every spot on Earth. As the Earth’s orbit cycles between more or less elliptical, seasonal extreme temperatures also vary.
Then there is the 22 year sun-spot cycle, which correlates with cycles of floods and droughts. Sunspots are indicators of solar activity which cause periods of global warming and cooling.
Earth also generates the less predictable El Nino climate events that have a huge effect on the global patterns of weather and temperature.
The least recognised but most dangerous climate cycle is the glacial cycle.
We live in the Holocene Epoch, the latest warm phase of the Pleistocene Ice Age. The climate history of the Holocene, and its predecessor the Eemian, are well documented in the ice core logs and other geological records. One cycle consists of a glacial age of about 80,000 years followed by a warmer age of about 20,000 years, with peak warming occurring over about 12,000 years. Our modern warm era commenced 12,000 years ago, so it is probably nearing its end.
There have been eight warm eras separated by long glacial winters over the last 800,000 years of the Pleistocene. In every beat of this cycle, the vast ice sheets melt, sea levels rise dramatically, coral reefs and coastal settlements are drowned, and forests and animals re-colonise the higher land released from the ice. Warm climate animals such as hippos, water buffaloes and elephants got as far north as Germany in the last warm era.
Then the ice returned, covering the northern hemisphere as far south as Chicago and London, destroying the forests, lowering the seas, stranding the relocated coral reefs and eliminating unprepared species. (Some dopey grizzly bears got stranded in the growing Arctic Ice and the most enterprising of them survived to evolve into white grizzlies now called polar bears.)
This regular repetition of natural climate change is best explained by the Milankovitch cycles relating to changes in Earth’s orbit and tilt. These drive variations in solar energy received by Earth and have the greatest temperature effect on the large land masses of the Northern Hemisphere.
Earth’s climate is never still for long.
On a longer time scale, passage of the solar system through the plane of the Galaxy seems to trigger magnetic reversals and violent spasms of volcanism, glaciation and species extinction.
What is the role of carbon dioxide in climate? Al Gore did a great job to dramatise the recurring cycles of glaciation and carbon dioxide in his widely acclaimed work of science fiction. But he missed two “inconvenient truths”.
First, the ice cores show that in the glacial spring-time the temperature rose BEFORE the CO2 levels rose. Therefore the rising CO2 cannot be a CAUSE of the warming – it is a RESULT of CO2 being expelled from the warming oceans.
Second, at the top of every summer-time in the glacial cycle, the high levels of CO2 in the atmosphere were totally unable to prevent the cooling into the next cycle of ice. CO2 levels fell later as the cooling oceans absorbed more CO2.
We are already in the autumn of the current glacial cycle and nothing man can do will change that. Global temperatures today are lower than they were in Roman and Medieval times. They will still fluctuate with the effects of daily, lunar, seasonal, yearly and sun-spot cycles, but the long-term trend of maximum and minimum temperatures will continue drifting downwards. As soon as summer temperatures in Siberia and northern Canada are unable to melt last winter’s snow, the growing glaciers will join to form ice sheets which reflect more solar radiation, and Earth will once again slip into another long hungry Glacial Winter.
The warm days, seasons, years and epochs have never been a deadly threat to life on Earth. Frost, snow, hail and ice are the killers. If our descendants do not have the energy, resources and wisdom to keep their people warm and fed through the coming glacial epoch, humans may follow our Neanderthal cousins who perished in the last glacial winter, just 20,000 years ago.
There is ZERO evidence in the climate record that carbon dioxide has a detectable effect on global temperatures. However if it does indeed slightly delay the onset of the next glacial winter, we and all life on Earth should count ourselves extremely lucky.
