A substantial stratospheric cooling event is now being observed over the Southern Hemisphere following a massive injection of water vapor

by A. Flis, Aug 29, 2022 in SevereWeatherEurope


Strong cold anomalies are being detected in the stratosphere over Southern Hemisphere. The anomalous cooling results from the water vapor coming from the January Hunga Tonga eruption. Cooling on this scale has not been seen in modern satellite records, so this is a significant event.

We will look at what is happening with temperatures in the southern stratosphere, how it all actually happened, and how it might impact our side of the planet in the upcoming Winter 2022/2023.

New Studies Claim The More CO2 In The Venus Atmosphere The Colder It Gets

by K. Richard, Aug 19, 2022 in NoTricksZone


Early Venus is suggested to have been much colder – and thus habitable – due to higher concentrations of CO2…because CO2 drives cooling in most of the Venus atmosphere (stratosphere, mesosphere, thermosphere).

Scientists have for decades agreed it is “well recognized” that CO2 molecules radiatively cool the atmospheres of planets like Earth, Mars, and Venus (Sharma and Wintersteiner, 1990) in the 15 μm band starting from 12 km above the surface on up.

Tokyo Midsummer Hasn’t Warmed In Decades. And: The Missing Hurricanes”.

by Kyrie, Aug 3, 2022 in NoTricksZone


Continuously increasing CO2 emissions into the atmosphere from the burning of fossil fuels is supposed to be causing warming all over the globe right now, so we should be seeing it in most of the trends.

But often we don’t. The globe, in fact, has cooled somewhat since the El Nino of 2015/16. The media refuse to report that.

One example of no warming is the midsummer mean for Tokyo and its rural Hachijojima island in the Pacific.

Tokyo

Looking at the July mean temperature trend for Tokyo itself, using data from the Japan Meteorological Agency (JMA), and not the adjusted datasets from NASA, we have the following:

The Sahara Is Green When Warm, Desert When Cold…And It’s Drier Now Than The Last Glacial Maximum

by K. Richard, Aug 1, 2022 in NoTricksZone


If wetter is warmer and drier is colder, the modern Saharan climate suggests we are not in a warm period.

It is common knowledge that warmer temperatures are associated with wetter, greener climates, and cooler temperatures are linked to droughts, browning, crop failures, etc.

For example, in the continental US there is a “robust association between pan-CONUS drought events and cold tropical Pacific conditions” (Baek et al., 2019). Again, cooling sea surface temperatures are the “principal driver” of drought across the US.

LARGEST SUMMER SEA ICE EXTENT SINCE 2008 TRAPS ARCTIC SHIPS; + COLDEST JULY AIRMASS IN 70 YEARS BLOWS THROUGH THE BERING STRAIT

by Cap Allon, July 19, 2022 in Electroverse


The mainstream are heat-chasers. They report only on stories that fit the AGW Party agenda. This cherry-picking leads to a painfully misinformed public when it comes to the climate–which is exactly where they want us.

It usually stands, however, that if the MSM goes silent on a particular locale then it’s probably because that particular locale isn’t ‘behaving’ as they would like.

ase in point today: we have the Arctic and Greenland refusing to play ball.

Earth’s most-northern reaches are actually experiencing persistent and long-lasting COOLING, which is far more telling than a brief burst of heat in, for example, Western Europe, which, 1) is forecast to be over before it’s even really begun, and 2) can be tied to entirely natural forcings–namely low solar activity and a violently ‘buckling’ jet stream flow (more on that below).

ALL-TIME COLD RECORDS FALL IN AUSTRALIA; + SOLAR ACTIVITY CONTROLS THE CLIMATE

by Cap Allon, Jul 5, 2022 in Electroverse


ALL-TIME COLD RECORDS FALL IN AUSTRALIA

Following its best start to a ski season ever, conditions have anomalously cold and snowy across swathes of Australia.

June 2022 finished with a temperature anomaly of -0.1C below the multidecadal average, according to data supplied by the Australian Bureau of Meteorology–whatever that’s worth.

The unusual chill has extended into July, too, and hundreds of monthly low temperature records have fallen over the past two days alone–particularly across the northeastern state of Queensland, where even a number of all-time benchmarks have been toppled.

 

Senior meteorologist Harry Clark said the combination of rain and cold temperatures was “extremely unusual” for July.

“Both in terms of the amount of rainfall and the extent of it, for what is one of our driest months of the year, but also for the extremely low maximum temperatures we’ve seen,” said Clarke. “Temperatures are looking more into what you might expect in Melbourne, or some of those southern capital cities where it’s the typical winter weather.”

Clarke confirmed that “many” cold weather records were broken across Queensland this week, with the standouts for him being Rockhampton peaking at only 12.5C (54.5F) yesterday, and Toowoomba struggling to just 7.6C (45.7F).

Other locales registered equally impressive readings: The Gold Coast Seaway set its coldest day of any month ever yesterday with 14C (57.2F); while further north, in Townsville, residents there suffered their coldest July day ever with a high of 15C (59F).

And most recently, Brisbane, the capital of Queensland –which had already registered its coldest start to a winter since 1904— has, today (July 5), gone and logged its coldest daily high in 22 years, reaching only 12.4C (54.3F).

For reference, Brisbane’s lowest-ever maximum remains the 12C (53.6F) set in July 2000; with the city’s third-coldest July maximum actually being yesterday’s 14.2C (57.6F) … but ‘catastrophic global warming’, you know … ?

SOLAR ACTIVITY CONTROLS THE CLIMATE

The global temperature record since 1880 is highly correlated to solar activity, and solar activity is highly correlated to the harmonics of planetary motion.

The below chart is NASA’s Historical Total Solar Irradiance Reconstruction, Time Series.

And looking ahead, Australia’s Antarctic blast isn’t forecast to abate anytime soon — quite the opposite, in fact:

 

Since 2000 The Arctic’s Hudson Bay Has Cooled -0.35°C With 10 Of 15 Sites Gaining Sea Ice

by Gupta et al.,  July 7, 2022 in NoTricksZone


A new study (Gupta et al., 2022) indicates that from 2000-2019 73% of the 15 sites considered have been cooling and 67% have experienced a lengthening of sea ice duration.

Canada’s Hudson Bay extends into the Arctic Ocean and its coasts are teeming with polar bears.

Scientists report 11 of 15 Hudson Bay sites have been cooling since 2000. The average cooling for these 11 sites is -0.34°C per decade.

Coldest, Wettest & Stormiest – The Good Old Days Before Global Warming

by P. Homewood, Jul 3, 2022 in NotatLotofPeopleKnowThat


By the 1970’s, the Earth had experienced three decades of declining temperatures, which Hubert Lambdescribed as “longest-continued downward trend since temperature records began”.

Many will be aware that the coldest winter on record in the US was that of 1978/79, more than 1F colder than any other year.

La Nina is Not Going Away. What Does This Mean for This Summer’s Weather?

by C. Mass, May 16, 2022 in WUWT


It is now clear that La Nina is not going away, and may hang around into next winter.  

Cold water is entrenched over the central and eastern tropical Pacific (the definition of La Nina) and the latest forecast model runs suggest a continuation into fall.

Several of you have asked:   what does this imply for our summer weather?

Let me tell you.

But first, the bottom line:   the summer effects of La Nina are modest, but will push the western side of our region towards cooler than normal conditions.

The Impacts

During La Nina years, sea surface temperatures off the West coast are usually cooler than normal, and those cooling effects spread inland.

To illustrate, here is the sea surface temperate difference from normal for the summer months (May through September) for La Nina years.    Blue colors are cooler than normal.

New Analysis Of Greenland’s GISP2 Temperatures Expose Selection Bias In Paleo Reconstructions

by K. Richard, Mar 17, 2022 in NoTricksZone


Scientists admit that 3 different Greenland Summit (GISP2) temperature reconstruction “strategies” produce 3 different paleoclimate temperature results. The reconstructions chosen as the most “robust” are therefore the ones that align best with the authors’ presuppositions.

In a new study published in Quaternary Science Reviews scientists (Döring and Luenberger, 2022) report they reject a reconstruction of Greenland Summit temperatures that shows it has cooled ~4°C since Roman times (shown below as the red trend line, extended to 2000 C.E.).

Greenland Sees Significant Snow, Ice Mass Loss Slowdown Over Past Decade, Danish Data Show

by P. Gosselin, Nov 14, 2021 in NoTricksZone


Data from the Danish Polar Portal shows Greenland ice melt slowing significantly over past 10 years. Increasingly rapid mass loss is a myth. 

German climate site Die kalte Sonne here looks at whether Greenland is really melting faster or not in its 78th climate and energy video (3rd segment).

Satellite measurement has allowed accurate measurements over the years and so reliable trends are detectable.

Greenland has added mass since July

Over the past year, since September 2020, Greenland has seen a number of heavy snowfalls, as depicted by the solid blue line in the chart by the Danish polarportal.dk:
