COGNITIVE BIAS : Climate Change Alarmists Refuse To Accept ‘The Science’ That Proves Extreme Weather Events Are NOT Increasing

By Jamie Spry

---

THE widely held belief that ‘Extreme Weather’ has become worse, as a result of man-made carbon dioxide emissions, is a tribute to the success of climate change propaganda pushed relentlessly by CO2-centric politicians and compliant mainstream media.

PROMOTING Extreme Weather is specifically designed to shift public opinion about the purported seriousness of human-induced global warming climate change, through the use of emotional imagery and dire prognostications in order for draconian and costly climate policy to be accepted and implemented with as little resistance as possible from the taxpaying public.

COGNITIVE BIAS fuelled by an era of mass hysteria, delusion, groupthink and panic has helped foster dark and far-fetched clichés of a current “climate crisis”, that is an “existential threat” which will “end civilisation by 2030”.

*

THANKS to the dramatic rise in personal weather recording devices – smart phones and CCTV – the sampling rate (what you see or hear directly) of Extreme Weather events, broadcast via social and mainstream media, has risen dramatically in recent years.

BUT, have actual Extreme Weather events increased in frequency or intensity? In particular, over long-term ‘climate’ scales?

THE short answer is a big fat NO! Extreme Weather events have not increased in frequency or intensity as carbon dioxide emissions have increased. In many cases the exact opposite is occurring.

THIS ‘inconvenient’ fact has been proven by empirical data and confirmed by the last two (warmist) U.N. IPCC reports on Extreme Weather: SREX (AR5) 2013 report and the latest SR15 report released August, 2018:

• SORRY ALARMISTS : The IPCC Once Again Reports Extreme Weather Events Have Not Increased | Climatism (SR15 2018)
• No steel roof required: IPCC dials back the fear of extreme weather | Climatism (SREX AR5 2013)

EXTREME WEATHER METRICS

DROUGHT

UN IPCC : “Low confidence in the sign of drought trends since 1950 at global scale…likely to be trends in some regions of the world, including increases in drought in the Mediterranean and W Africa & decreases in droughts in central N America & NW Australia” – UN IPCC SR15 (2018)

GLOBAL TREND

*

NO historical trend in U.S. drought as CO₂ rises :

*

1934 : WHEN CO₂ WAS AT ‘SAFE’ LEVELS

IN 1934, when CO₂ was at ‘safe’ levels, severe to extreme drought covered around 80% of the entire U.S. Such conditions endured for most of the decade known as the “Dust Bowl” era :

*

400 PPM ‘DANGEROUS’ CO₂

CURRENT U.S. drought conditions with CO₂ at ‘dangerous’ levels (400PPM) :

*

CALIFORNIA’s “PERMANENT DROUGHT” UPDATE

THANKS to superstitious climate kiddies wagging school, in just 3 years, California went from 97% in drought to just 1% :

*

WHEN CO₂ was at ‘safe’ levels, droughts in California lasted for 200 years :

***

FLOODS

“There is low confidence due to limited evidence, however, that anthropogenic climate change has affected the frequency and the magnitude of floods.” – UN IPCC SR15 (2018)

***

HEATWAVES

ACCORDING to the EPA, the low-CO2 1930s had (by far) the worst heatwaves in US history :

*

WHEN CO₂ was at ‘safe levels’, Adelaide’s temperature climbed above 100°F, six days in a row.

ADELAIDE – March, 1940 :

1. Friday  –  24°C (74.4F)
2. Saturday  –  24°C (75.7F)
3. Sunday  –  28°C (81.7F)
4. Monday  –  34°C (93.5F)
5. Tuesday  –  31°C (88.4F)
6. Wednesday  –  35°C (94.9F)
7. Thursday  –  40°C (103.9F)
8. Friday  –  42°C (107.7F)
9. Saturday  –  43°C (110.1F)
10. Sunday  –  42°C (108.3F)
11. Monday  –  42°C (107.9F)
12. Tuesday  –  40°C (103.6F)

GLOBAL TROPICAL CYCLONES

“Numerous studies towards and beyond AR5 have reported a decreasing trend
in the global number of tropical cyclones and/or the globally accumulated cyclonic energy”– UN IPCC SR15 (2018)

“There is only low confidence regarding changes in global tropical cyclone numbers under global warming over the last four decades.” – UN IPCC SR15 (2018)

*

AUSTRALIAN TROPICAL CYCLONES

AUSTRALIAN tropical cyclones are declining in both intensity and frequency as CO₂ rises :

***

HURRICANES

GLOBAL Hurricanes are declining in both frequency and intensity as CO₂ increases :

*

*

CAT 3+ U.S. Landfalling Hurricanes (per decade) declining rapidly as CO₂ emissions rise :

*

FLORIDA Major Hurricane Strikes – Still No Trend :

***

TORNADOES

2018 was one of the least active US tornado years on record, despite record and rising CO₂ emissions.

AS of October, a new record low tornado count was set. The cumulative total for 2018 is 759; the previous lowest number of tornadoes for this date was 761. The SPC has records extending back 65 years.

This lack of tornadic storms in recent years should also correlate with lesser severe thunderstorm activity in general in the U.S., since the conditions which produce large hail and damaging winds are generally the same as are required for tornadoes (strong instability, plentiful moisture, and wind shear). – Roy Spencer PhD

NB// The US represents about 75 percent of the world’s recorded tornadoes.

*

*

THE frequency of strong to violent tornadoes is also decreasing :

*

*

THE trend is clearly down across the board. Yet why are no mainstream journalists curious about this?

NB// IPCC SR15 “Extreme Weather” report made no mention of Tornadoes. Nor, the mainstream media!

***

GLOBAL WEATHER DISASTERS / LOSSES

GLOBAL weather disasters/losses as a percentage of global GDP are declining as CO₂  emissions rise.

THROUGH 7 months of 2018 weather disasters as % GDP were on record (low) pace…

NB// LOSS data does not include the two big CAT4’s that struck the US in 2018 – Florence (Sep) and Michael (Oct).

CONCLUSION

BIAS BY OMISSION

IN my opinion, the worst form of propaganda is ‘bias by omission’ – information and facts that you are ‘not’ told about, in order to keep the truth from you.

THE mainstream media has not and will not report the facts on “Extreme Weather”, as clearly laid out in the science and data above, because such facts are obviously extremely ‘inconvenient’ to their “catastrophic” man-made global warming narrative.

*

VITAL information central to the potential seriousness of climate change – Extreme Weather – has been purposely omitted by the mainstream media and replaced by emotions, alarmism and exaggerations in order to fit the climate-calamity narrative designed to scare you into belief and obedience.

THIS is why the global warming climate change debate has become so dangerously deceptive and dishonest. Climate truths hidden from you and replaced with a narrative far more acceptable – Hollywood-style climate hysteria based on alarmism, increased sampling rates and overheated, CO2-centric climate models that do not accord with observed reality.

UPDATE

DID not see either of these instructive graphs painted on a placards at any of the kiddie climate rallies last Friday. Guess they don’t fit their ‘catastrophic’ climate narrative…

*

PERHAPS the climate kids would have been wise to read and learn the words of H.L. Mencken, before being forced out by their parents and teachers to act as standard bearers of new radical eco-socialism, protected by ‘innocence’ and lack of age :

“The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary. The urge to save humanity is almost always a false front for the urge to rule it.” – H.L. Mencken
