25 simple bullet points proving #CO2 does not cause #GlobalWarming: by a #geologist for a change

Image result for climate change is a hoax images

1) Geologists know climate change unrelated to atmospheric CO2 occurred throughout Earth’s 4.5-billion-year history. Yet the IPCC (United Nations Intergovernmental Panel on Climate Change) has no geologists among the hundreds of appointed authors of its Fifth Assessment Report of 2014 and its Sixth Report due in 2022 (see my Technical Note 2019-10). Thus IPCC incredibly lacks both geological input and long-term perspective.

2) IPCC’s very existence relies on public belief in manmade or ‘anthropogenic’ global warming (AGW) by CO2 emissions. Moreover its appointed authors, mostly government and university researchers, are nearly all biased by strong vested interests in AGW, i.e. reputations (publications, lectures) & continuance of salaries & research grants. Similarly, major universities have abandoned their scientific impartiality & integrity by hosting research institutes mandated to confirm & act on AGW, e.g. Grantham Institute (Imperial College), Tyndall Centre.

3) The often-repeated ‘97% consensus among scientists that global warming is man’s fault’ (CO2 emissions) is untrue. It refers in fact to surveys of just a relatively small group of ‘climate scientists’ (a fairly new type of scientist, with strong incentives for bias; see Bullets 2 & 15), moreover only those who are ‘actively publishing’.

4) ‘Climate change denier’ & ‘global warming denier’ are despicable & dishonest terms for ‘AGW doubters’. No educated person disputes global warming, as thermometers measured 1°C rise from 1850 to 2016 (with pauses).

5) The ‘Greenhouse Hypothesis’, on which IPCC’s belief in AGW is based, is that atmospheric gases trap heat. But this old (19th century) notion is merely an idea, not a hypothesis, because it is untestable, impossible to prove in a laboratory as no experimental container can imitate Earth’s uncontained, well-mixed atmosphere.

6) IPCC computer models are so full of assumptions as to be extremely unreliable, e.g. forecast warming for 1995 to 2015 turned out to be 2-3 times too high ! A likely reason is that the greenhouse idea is nonsense, as explained in recent publications by several scientists. See Bullet 19 for an equally drastic failure of IPCC models. See also https://www.wnd.com/2017/07/study-blows-greenhouse-theory-out-of-the-water/https://principia-scientific.org/r-i-p-greenhouse-gas-theory-1980-2018/

7) For about 75% of the last 550 million years, CO2 was 2 to 15 times higher than now. Evolution flourished, CO2 enabling plant photosynthesis, the basis of all life. Extinction events due to overheating by CO2 are unknown. !!

8) Through the last 12,000 years (our current Holocene interglacial period), CO2 was a mere 250 to 290 ppm (parts per million), near plant-starvation level, until about 1850 when industrial CO2 emissions began, making CO2 climb steeply. Nevertheless CO2 today it is still only 412ppm, i.e. under half of one-tenth of 1% of our atmosphere

9) Until man began adding CO2 about 1850, warming (determined from ‘proxies’ like tree rings) since the 1600AD Little Ice Age peak was accompanied by slowly rising CO2 (measured in ice cores). A simple explanation is CO2 release by ocean water, whose CO2-holding capacity decreases upon warming.

10) Supporting this sign that CO2 is a consequence, not cause, of global warming, a published study of 1980-2011 measurements showed that changes in warming rate precede changes in CO2’s growth rate, by about a year.

11) Since the 1850 start of man’s additions, CO2’s rise has generally accelerated, without reversals. In stark contrast, the post-1850 to present-day continuance of warming out of the Little Ice Age was interrupted by frequent small coolings of 1-3 years (some relatable to ‘volcanic winters’), plus two 30-year coolings (1878 to 1910, 1944 to 1976), and the famous 1998 to 2013 ‘global-warming pause’ or ‘hiatus’ (Wiki).

12) This unsteady modern warming instead resembles the unsteady rise of the sun’s magnetic output from 1901 toward a rare solar ‘Grand Maximum’ peaking in 1991, the first in 1700 years !

13) Modern warming reached a peak in February 2016. Since then, Earth has cooled for 3 years (now April 2019).

14) The ‘Svensmark Theory’ says increased solar magnetic flux warms Earth by deflecting cosmic rays, thus reducing cloudiness, allowing more of the sun’s warmth to heat the land and ocean instead of being reflected. In support, a NASA study of satellite data spanning 32 years (1979-2011) showed decreasing cloud cover.

15) Vociferous IPCC-involved climate scientist Dr Stefan Rahmstorf (Wiki) of the German government’s Potsdam Institute for Climate Impact Research, recipient of a US$1 million personal research grant from a private foundation, wrongly said in his 2008 article ‘Anthropogenic Climate Change’: “there is no viable alternative … [to CO2 as driver of modern warming from 1940 to 2005 because] … different authors agree that solar activity did not significantly increase” during that period. Yet nine years earlier, in 1999, famous physicist Dr Michael Lockwood (Wiki; FRS) wrote, in ‘A Doubling of the Sun’s Coronal Magnetic Field During the Past 100 Years’, published in prestigious Nature journal: “the total magnetic flux leaving the Sun has risen by a factor of 1.4 since 1964” and 2.3 since 1901 !! See for yourselves the striking overall 1964-91 climb in solar-magnetic output, recorded by the strong overall fall in detected neutrons (proportional to cosmic rays), in graph 3 here … https://cosmicrays.oulu.fi

16) Lockwood showed averaged solar magnetic flux increased 230% from 1901 to 1995, i.e. more than doubled ! The final peak value was 5 times the starting minimum value ! Bullets 17 & 18 likewise back Svensmark’s theory…

17) … after the previous solar Grand Maximum (4th century, long before industrial CO2), in the next decades Earth warmed to near or above today’s temperature. Then ‘sawtooth’ cooling proceeded, through the Dark Ages and ‘Medieval Warm Period’, into the Little Ice Age, paralleling a 1,000-year unsteady solar decline; and …

18) … before that, between 8000 and 2000BC, Earth was occasionally warmer than today for hundreds if not thousands of years, as shown by tree rings, shrunken glaciers, etc.. Then unsteady cooling from 3000BC into the Little Ice Age paralleled unsteady solar decline following the Holocene’s ‘super-Grand’ Maximum near 3000BC.

19) This 4,500-year cooling contradicts IPCC computer models that instead predict warming by the simultaneous (slow) rise in CO2. This is the ‘The Holocene Temperature Conundrum’ of Liu et al. (2014). See also Bullet 6.

20) Embarrassingly for AGW promoters, the 8000-2000BC warm interval (Bullet 18) was already, ironically, named the ‘Holocene Climatic Optimum’, before today’s CO2/AGW hysteria began. The warmth probably benefitted human social development. Indeed, it was cold episodes, bringing drought and famine, that ended civilisations.

21) Cross-correlating post-1880 graphs of solar-magnetic flux versus Earth’s temperature suggests a 25-year time-lag, such that the 2016 peak temperature corresponds to the 1991 solar peak. The lag is probably due to the ocean’s high thermal inertia due to its enormous volume and high heat capacity, hence slow response to warming.

22) IPCC, ignoring the possibility of such a time-lag, claims that simultaneous global warming (until 2016) and solar weakening (since 1991) must mean that warming is driven by CO2 !

23) The last interglacial period about 100,000 years ago was warmer than our Holocene interglacial. Humans and polar bears survived ! CO2 was then about 275ppm, i.e. lower than now (Bullet 8).

24) The simultaneous rise of temperature & CO2 is a ‘spurious correlation’. Warming’s real cause was a solar build-up to a rare Grand Maximum, which man’s industrialisation accompanied by chance. So IPCC demonising CO2 as a ‘pollutant’ is a colossal blunder, costing trillions of dollars in needless & ineffectual efforts to reduce it.

25) Global cooling now in progress since February 2016 can be predicted to last at least 28 years (i.e. to 2044), matching the sun’s 28-year decline from 1991 to today, and allowing for the 25-year time-lag (Bullet 21).

Inescapable conclusion: IPCC is wrong − the sun, not CO2, drove modern global warming

Why #Scientists Who Know #ClimateChange Isn’t Causing #ExtremeWeather Stay Quiet

Climate Change Hoax Alert

This week in Vancouver, Prime Minister Trudeau said the federal carbon tax, a key pillar in his government’s climate policy, will help protect Canadians from extreme weather.

“Extreme weather events are extraordinarily expensive for Canadians, our communities and our economy,” he said, citing the recent tornadoes in Ottawa and wildfires in Western Canada. “That’s why we need to act.”

While members of the media may nod along to such claims, the evidence paints a different story.

Roger Pielke Jr. is a scientist at the University of Colorado in Boulder who, up until a few years ago, did world-leading research on climate change and extreme weather.

He found convincing evidence that climate change was not leading to higher rates of weather-related damages worldwide, once you correct for increasing population and wealth.

He also helped convene major academic panels to survey the evidence and communicate the near-unanimous scientific consensus on this topic to policymakers.

For his efforts, Pielke was subjected to a vicious, well-funded smear campaign backed by, among others, the Obama White House and leading Democratic congressmen, culminating in his decision in 2015 to quit the field.

A year ago, Pielke told the story to an audience at the University of Minnesota. His presentation was recently circulated on Twitter. With so much misinformation nowadays about supposed climate emergencies, it’s worth reviewing carefully.

Pielke’s public presentation begins with a recounting of his rise and fall in the field.

As a young researcher in tropical storms and climate-related damages, he reached the pinnacle of the academic community and helped organize the so-called Hohenkammer Consensus Statement, named after the German town where 32 of the leading scientists in the field gathered in 2006 to sort out the evidence.

They concluded that trends toward rising climate damages were mainly due to increased population and economic activity in the path of storms, that it was not currently possible to determine the portion of damages attributable to greenhouse gases, and that they didn’t expect that situation to change in the near future.

Shortly thereafter, the Intergovernmental Panel on Climate Change (IPCC) released its 2007 report, largely agreeing with the Hohenkammer Consensus, while cherry-picking one unpublished study (and highlighting it in the Summary for Policymakers) that suggested a link between greenhouse gases and storm-related damages.

But the author of that study — who just happened to be the same IPCC lead author who injected it into the report — later admitted his claim was incorrect, and when the study was finally published, denied the connection.

In 2012, the IPCC Special Report on Extreme Weather came out and echoed the Hohenkammer Consensus, concluding that once you adjust for population growth and economic changes, there is no statistical connection between climate change and measures of weather-related damages.

In 2013, Pielke testified to the United States Congress and relayed the IPCC findings.

Shortly thereafter, Obama’s science advisor John Holdren accused him of misleading Congress and launched a lengthy but ill-informed attack on Pielke, which prompted congressional Democrats to open an investigation into Pielke’s sources of funding (which quickly fizzled amid benign conclusions).

Meanwhile, heavily funded left-wing groups succeeded in getting him fired from a popular internet news platform. In 2015 Pielke quit the climate field.

So where did the science end up?

In the second half of his talk, Pielke reviews the science as found in the most recent (2013) IPCC Assessment Report, the 2018 U.S. National Climate Assessment, and the most up-to-date scientific data and literature. Nothing substantial has changed.

Globally there’s no clear evidence of trends and patterns in extreme events such as droughts, hurricanes, and floods. Some regions experience more, some less and some no trend.

Limitations of data and inconsistencies in patterns prevent confident claims about global trends one way or another. There’s no trend in U.S. hurricane landfall frequency or intensity.

If anything, the past 50 years has been relatively quiet. There’s no trend in hurricane-related flooding in the U.S. Nor is there evidence of an increase in floods globally.

Since 1965, more parts of the U.S. have seen a decrease in flooding than have seen an increase. And from 1940 to today, flood damage as a percentage of GDP has fallen to less than 0.05 percent per year from about 0.2 percent.

And on it goes. There’s no trend in U.S. tornado damage (in fact, 2012 to 2017 was below average). There’s no trend in global droughts. Cold snaps in the U.S. are down but, unexpectedly, so are heatwaves.

The bottom line is there’s no solid connection between climate change and the major indicators of extreme weather, despite Trudeau’s claims to the contrary.

The continual claim of such a link is misinformation employed for political and rhetorical purposes. Powerful people get away with it because so few people know what the numbers show.

Many scientists who know better remain silent. And the few who push back against the propaganda, such as Roger Pielke Jr., find themselves on the receiving end of abuse and career-threatening attacks, even though they have all the science in their corner.

Something has gotten scary and extreme, but it isn’t the weather.
