SANTA CATARINA, BRAZIL LOGS ITS THIRD CONSECUTIVE DAY OF RARE SNOW AND SUB-ZERO COLD

by Cap Allon, July 2, 2021 in Elecrroverse


Santa Catarina recorded snowfall in Urupema and Sao Joaquim on Wednesday — the third consecutive day of the rare phenomenon, which also included unusually chilly sub-zero temperatures.

Santa Catarina is the southernmost state of Brazil.

Temperatures across the state have plunged to a record-challenging -7.5C (18.5F), and beyond, this week, and heavy snow has been registered.

According to the Information Center of Environmental Resources and Hydrometeorology of Santa Catarina (Epagri / Ciram), this is the first year since 2000 that snow has been recorded on three consecutive days.

As reported by riotimesonline.com, plunging temperatures and favorable humidity levels have brought substantial accumulations of snow to the towns and cities located in and around the Santa Catarina Mountains

 

Five Asian countries account for 80% of new coal power investment

by J. Ambrose, One 30, 2021 in TheGuradian


Five Asian countries are jeopardising global climate ambitions by investing in 80% of the world’s planned new coal plants, according to a report.

Carbon Tracker, a financial thinktank, has found that China, India, Indonesia, Japan and Vietnam plan to build more than 600 coal power units, even though renewable energy is cheaper than most new coal plants.

The investments in one of the most environmentally damaging sources of energy could generate a total of 300 gigawatts of energy – enough to power the UK more than three times over – despite calls from climate experts at the UN for all new coal plants to be cancelled.

Catharina Hillenbrand von der Neyen, the author of the report, said: “These last bastions of coal power are swimming against the tide, when renewables offer a cheaper solution that supports global climate targets. Investors should steer clear of new coal projects, many of which are likely to generate negative returns from the outset.”

Greenland Ice Core CO2 during the past 1,000 years


by R. Hannon, July 2, 2021 in WUWT


Introduction
This post compares CO2 ice core measurements from Greenland to those from Antarctica over the last millennium. Paleoclimate studies typically use only Antarctic ice cores to evaluate past CO2 fluctuations. This is because the entire Greenland CO2 datasets were deemed unreliable due to chemical reactions with impurities in the ice and therefore have not been used in studies since the late 1990’s. This post will demonstrate that CO2 data from Greenland ice cores have scientific value and respond to key paleoclimate events such as the Little Ice Age and Medieval Warm Period.

Antarctic Ice Core CO2 Trends
Antarctic ice CO2 data is readily available and has been studied extensively (Bauska, 2015, Ahn, 2012, Siegenthaler, 2005 and Rubino, 2019). Most of the focus of recent studies has been on high snow accumulation sites which tend to have higher resolution and less smoothing of the trapped gas age in ice bubbles due to the firn to ice transition. Gas age width and resolution ranges from 10 years in Law Dome ice cores to 65 years in Dronning Maud Land DML. Figure 1 shows CO2 data from Antarctic high-resolution ice cores over the past millennium.

Ahn et al, 2012, compiled CO2 records from the West Antarctic Ice Sheet (WAIS) and compared them to other key datasets such as Dronning Maud Land (DML), and Law Dome. Their study recognizes and discusses elevated CO2 during the Medieval Warm Period (MWP) at 1000 AD, decrease of CO2 around 1600 AD during the Little Ice Age (LIA) and the subsequent rapid increase beginning around 1850 AD.

UAH Global Temperature Update for June 2021: -0.01 deg. C

by Roy Spencer, July 3, 2021 in WUWT


The Version 6.0 global average lower tropospheric temperature (LT) anomaly for June, 2021 was -0.01 deg. C, down from the May, 2021 value of +0.08 deg. C.

REMINDER: We have changed the 30-year averaging period from which we compute anomalies to 1991-2020, from the old period 1981-2010. This change does not affect the temperature trends.

The linear warming trend since January, 1979 remains at +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).

 

Greenland Temperatures & The AMO

by P. Homewood, June 13, 2021 in NotaLotofPeopleKnowThat


It’s not new, but it’s worth going over it again.

We have seen how Greenland temperatures rose sharply in the 1920s, and remained at levels similar to the last decade until the 1960s, when they fell equally sharply. This change in climate is closely interlinked with the Atlantic Multidecadal Oscillation (AMO), which switches from cold to warm phase, and back again, roughly every 50 to 60 years:

US Government Tries To Erase Historical Forest Fire Data To Fabricate Another Fake Crisis

by P. Gosselin, June 8, 2021 in NoTricksZone


The US government deletes more than 50 years of early data on forest fires in order to make it look like forest fires are more widespread, and linked to CO2. Should be Investigated under the RICO Act. 

There’s a reason why Smokey the Bear has been around more than 75 years with his message. “Only you can prevent forest fires.” The US government had known for decades that forest fires were a serious problem – much more serious than today.

They have forest fire data going back over 100 years. But suddenly, since January of this year, the US government is acting like there had never been a Smokey the Bear before 1983 and that forest fires are just a recent problem caused by manmade climate change.

It’s all a fraud, explains data analyst and software expert Tony Heller in his latest video.

Antarctica wasn’t quite as cold during the last ice age as previously thought

by OREGON STATE UNIVERSITY, June 6, 2021 in WUWT


CORVALLIS, Ore. – A study of two methods for reconstructing ancient temperatures has given climate researchers a better understanding of just how cold it was in Antarctica during the last ice age around 20,000 years ago.

Antarctica, the coldest place on Earth today, was even colder during the last ice age. For decades, the leading science suggested ice age temperatures in Antarctica were on average about 9 degrees Celsius cooler than at present.

An international team of scientists, led by Oregon State University’s Christo Buizert, has found that while parts of Antarctica were as cold as 10 degrees below current temperatures, temperatures over central East Antarctica were only 4 to 5 degrees cooler, about half of the previous estimates.

The findings were published this week in Science.

“This is the first conclusive and consistent answer we have for all of Antarctica,” said Buizert, an Oregon State University climate change specialist. “The surprising finding is that the amount of cooling is very different depending on where you are in Antarctica. This pattern of cooling is likely due to changes in the ice sheet elevation that happened between the ice age and today.”

Understanding the planet’s temperature during the last ice age is critical to understanding the transition from a cold to a warm climate and to modeling what might occur as the planet warms as a result of climate change today, said Ed Brook, a paleoclimatologist at OSU and one of the paper’s co-authors.

India, Australia, China, Russia pushing ‘massive’ coal expansion

by Ians, June 5, 2021 in Energyworld


Coal producers are actively pursuing 2.2 billion tonnes per annum of new mine projects around the world, a growth of 30 per cent from current production levels, a new report from Global Energy Monitor said on Thursday.

The first-of-its-kind analysis surveyed 432 proposed coal projects globally and found a handful of provinces and states in China, Russia, India, and Australia are responsible for 77 per cent (1.7 billion tonnes per annum) of new mine activity. If developed, these proposed projects boost supply to over four times the 1.5 degrees Celsius-compliant pathway necessary to meet the goal of the Paris climate agreement.

While three-fourths (1.6 billion tonnes per annum) of proposed coal mine capacity is in the early stages of planning and thus vulnerable to cancellation, the report finds one quarter (0.6 billion tonnes per annum) of proposed mine capacity is already under construction. The prospect of a low-carbon transition and tighter emission policies put these projects at risk of becoming up to $91 billion in stranded assets.

CARBON CYCLE

by C. Spencer, June 7, 2021 in WUWT


The increase in 12C in the atmosphere is, in my opinion, weak evidence that the annual increases are driven only by fossil fuel sources. The atmosphere can’t tell ‘anthropogenic’ carbon dioxide from natural carbon dioxide. It seems unlikely that a source that represents only about 4% of the total flux is going to drive the system. The oceans sequester the vast majority of the carbon. One would expect that warming oceans (from whatever forcing) would increase the rate of out-gassing in mid-latitudes, and decrease the rate of extraction at high-latitudes. It seems more reasonable to me that, in a world with warming oceans, there would be a shift in the relative amounts of carbon in the oceans and the atmosphere. That would be the case even in the absence of any anthropogenic carbon.

The Manichean Mann

by M. Hulme, June 2021 in IssuesinSci&Techn


Michael Mann has been in the climate wars for well over a decade now. As he reminds us frequently in this new book, he has been in the crosshairs of his enemies, has fought off the attack dogs, and carries the scars of battle. Even the environmentalist Bill McKibben’s promotional puff for the book valorizes Mann in terms of his “scars from the climate wars.” The military framing of climate change long predates Mann’s involvement, but it certainly is a framing he has done much to promote through his blogs, tweets, and general persona-at-large in public discourse.

And so it is not surprising that Mann’s new book continues his characterization of the politics of climate change through a series of complex military tropes and metaphors. Wars, battles, attacks, fights, and enemies litter its 260 pages. Much of what I said about Mann’s combative militancy in my review of his 2012 book, The Hockey Stick and the Climate Wars: Dispatches from the Front Lines, can be equally applied to this new one. Now, his central argument is that there is a new war afoot. The old war—fought mostly around the claims of climate scientists—has been (largely) won. But a new war has been ignited; Mann and his allies are now having to fight against the forces of inaction.

Mann is half right in his diagnosis. The main axes of public dispute and argumentation about climate change have changed. The politics of climate change manifest differently now than they did a decade ago. More centrally in focus—and this is a good thing—are the substantive and pressing questions about the sorts of actions, policies, and interventions that are needed, appropriate, and effective to attenuate the risks of a changing climate. What are their respective costs and benefits? How do different options interact with diverse cultural values and collide with vested interests? How do they complicate international geopolitics?

So in this observation Mann is correct. The focus of the issue has moved from “is there a problem?” to “what should be done about it?”

No sign of a climate emergency

by GWPF, May 29, 2021


A new review of weather and climate data based on observational data from 2020 finds little evidence to support the idea of a “climate emergency”.

 

The annual report, by Professor Ole Humlum, reviews a wide range of temperature and weather data, as well as records on sea-level, storms and ice and snow cover.

Temperature records for the Earth’s surface show that 2020 was a comparatively warm year, but that by the end of the year there was a marked cooling driven by natural ocean cycles in the Pacific. This cooling was also observed higher in the atmosphere.

Sea ice levels globally remained low, but are now increasing in the Southern Hemisphere. Global snow cover remained stable and there is still no significant trend in tropical storms.

Professor Humlum said:

The weather and weather extremes we are experiencing are still dominated by natural fluctuations. Rapid and frightening changes are nowhere to be seen in the observational data as this annual review shows.”

MONTHLY LOW TEMPERATURE RECORDS FALL IN VANUATU, AS LATE-SEASON SNOW AND UNPRECEDENTED COLD SWEEP TORONTO, CANADA

by Cap Allon, May 29, 2021 in Electroverse


The “crazy conspiracy theorists” are being proved right, again. But it was never crazy conspiracies that were being theorized. The outspoken few were merely “applying logic” — a skill the impaired herds were educated out of a long time ago, as children, in the indoctrination stations known as schools.

The world is corrupt — most people are all too happy to agree with this statement.

We are being lied to at every corner of life— yet most people struggle with this one.

MONTHLY LOW TEMPERATURE RECORDS TUMBLE IN VANUATU

Following on the heels of New Zealand’s all-time cold, record lows are now sweeping the Y-shaped South Pacific Ocean archipelago of VANUATU–which consists of roughly 83 volcanic islands and stretches approx. 1,300 kilometres.

On May 27, the mercury sank to 14.3C (57F) at Pekoa Airport, located on Espiritu Santo Island

On May 28, a low of 12.5C (54.5F) was registered at the Port Vila Airport, situated on Efate Island.

Both readings are new record lows for the month of May.

LATE-SEASON SNOW AND UNPRECEDENTED COLD SWEEP TORONTO, CANADA

May 28 was a historic ‘double-whammy’ of a day in Toronto, Canada.

First off, the day entered the weather books as the city’s coldest May 28 ever recorded, according to Environment Canada warning preparedness meteorologist Peter Kimbell.

The daytime high had only reached a frigid 4C (39.2F) by Friday afternoon.

For the next coldest May 28 you have to turn all the way back in 1889, according to books for downtown Toronto dating back to 1840. In other words, it’s been 130 years since Torontonians have suffered a May 28 this cold.

“Likelihood Of A Sub-Cooled Summer For Europe In 2021”, Hale Solar Cycle Suggests

by Dr Ludger Laurenz, May 30, 2021, in NoTricksZone


So far, much of Europe has seen a cold and wet 2021. It may be related to solar cycles. 

An essay at Die kalte Sonne by Dr. Ludger Laurenz looks at the relationship between solar activity and weather trends, and believes this summer’s temperature will be 1.5°C lower.

There are many scientific opinions about solar activity’s impact on weather and climate, which differ and contradict each other. For example, a new publication by Leamon et al. provides an important building block for uncovering solar influence. Background here.

Solar influence in historical climate data substantiated

In the Leamon et al publication, the authors looked at the 22-year Hale solar cycles and saw it is possible to detect and substantiate solar influence in historical climate data (from tropical ocean surface temperature to temperature, sunshine, and precipitation data) and to make quantitative statements about the influence of solar activity on weather data.

Norway winter temperature and sun: “high statistical significance”

“Using the alternating years between Hale cycles, a correlation between the 22-year Hale cycle of the Sun and the trend of winter temperature in the polar night of Norway can be demonstrated with high statistical significance,” Dr Laurenz adds.

“Parallel to the temperature trend, the solar influence of the Hale cycles is also evident in the index values of the North Atlantic and Arctic Oscillations,” says Laurenz  in addition. “Evidence of the influence of solar activity in the polar night of Scandinavia demonstrates that differences in solar activity are transmitted to the near-surface temperature via amplification mechanisms such as change in circulation patterns in the North Atlantic and Arctic Oscillations.”

The sun’s role in weather patterns is a great significance, and so CO2 is not the main driver at all.

NYIRAGONGO VOLCANO ERUPTS TO 45,000 FEET: DR CONGO ORDERS CITYWIDE EVACUATIONSp Allon,

by Cap Allon, May 23, 2021 in Electroverse


Nyiragongo’s deadliest eruption in history was that of 1977 (during the weak solar minimum of cycle 20) — this event went down as a VEI 1, according to historical observations, yet still managed to kill more than 600 people.

Saturday evening’s eruption looks bigger.

This was likely the volcano’s strongest eruption in recorded history.

UPTICK

Seismic and Volcanic activity has been correlated to changes in the Sun.

The recent global uptick in earthquakes and volcanic eruptions is likely attributed to the drop-off in solar activity, coronal holes, a waning magnetosphere, and the increase in Galactic Cosmic Rays penetrating silica-rich magma.

The COLD TIMES are returning, the mid-latitudes are REFREEZING, in line with a volcanic uptickthe great conjunction, historically low solar activitycloud-nucleating Cosmic Rays, and a meridional jet stream flow (among other forcings).

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.

CO2 Cyclone Doomsday Flat Out Refuted: 170 Years “Absolutely No Trend” In Hurricane Intensity/Frequency

by P. Gosselin, May, 22, 2021 in NoTricksZone


The latest comes from statistics expert, Zoe Phin, who looks at the alarmists’ claim that increasing CO2 emissions are leading to more frequent and intense Atlantic hurricanes.

Alarmist claims cost nothing, and so easily made. Zoe Phin looks at whether the hurricane alarmist claim holds up.

Frequency

First Zoe looked at the (HURDAT2) data to find out if the first of the two claims (increasing frequency) is true. At first glance it would appear so.

But Zoe asks if the method of measuring the frequency really is sensible and if it maybe weren’t better to measure the amount of time the Atlantic spends in hurricane mode? To find out, Zoe plotted the hurricane hours data and the 10-year moving average:

New Study Casts Doubt On Controversial Theory Linking Melting Arctic To Severe Winter Weather

by P. Voosen, May 13, 2021 in ClimagteChangeDispatch


Every time severe winter weather strikes the United States or Europe, reporters are fond of saying that global warming may be to blame.

The paradox goes like this: As Arctic sea ice melts and the polar atmosphere warms, the swirling winds that confine cold Arctic air weaken, letting it spill farther south.

But this idea, popularized a decade ago [and was the outlandish plotline in The Day After Tomorrow, pictured], has long faced skepticism from many atmospheric scientists, who found the proposed linkage unconvincing and saw little evidence of it in simulations of the climate.

Now, the most comprehensive modeling investigation into this link has delivered the heaviest blow yet: Even after the massive sea ice loss expected by midcentury, the polar jet stream will only weaken by tiny amounts—at most only 10% of its natural swings.

And in today’s world, the influence of ice loss on winter weather is negligible, says James Screen, a climate scientist at the University of Exeter and co-leader of the investigation, which presented its results last monthat the annual meeting of the European Geosciences Union.

Wandering polar bears are the new starving polar bears, falsely blamed on climate change

by Polar Bear Science, May 15 , 2021


Back in 2017, we famously had National Geographic falsely blaming a starving polar bear on climate change but since then we have been inundated (relatively speaking) with stories of ‘wandering’ bears sighted far from Arctic coastlines. These wandering bears are oddities to be sure but are not in any way an indicator of melting Arctic sea ice or lost habitat, as The Times (UK) has claimed in this latest example (Polar bear treks 1,500 miles south as Arctic hunting zone melts away).

The Greenhouse Effect In A Water World

by B. Irvine, May 17, 2021 in WUWT


A knowledge of Greenhouse gases is fundamental to any understanding of global surface temperatures. The presence of GHGs in our atmosphere has increased the global surface temperature by about 33C.

There are multiple lines of evidence, however, that challenge the strong water vapour feedback to a small initial CO2 forcing.  These strong positive feedbacks are central to the IPCC narrative.

These lines of evidence include.

  • The failure of all models and catastrophic warming projections.
  • The stubborn refusal of atmospheric Precipitable Water Vapour (PWV) concentration to rise in recent years.
  • The strength of convection cells in the tropics that have kept tropical temperatures approximately the same for many millions of years.
  • Irrigation and extra humidity generally coincide with cooler temperatures.
  • The hot spot as a signature of the positive Water Vapour (WV) feedback and its opposite, the negative lapse rate feedback, has not occurred.

Does ocean acidification alter fish behavior? Fraud allegations create a sea of doubt

by P. Homewood, May 7, 2021 in NotaLotofPeopleKnowThat


When Philip Munday discussed his research on ocean acidification with more than 70 colleagues and students in a December 2020 Zoom meeting, he wasn’t just giving a confident overview of a decade’s worth of science. Munday, a marine ecologist at James Cook University (JCU), Townsville, was speaking to defend his scientific legacy.

But their work has come under attack. In January 2020, a group of seven young scientists, led by fish physiologist Timothy Clark of Deakin University in Geelong, Australia, published a Nature paper reporting that in a massive, 3-year study, they didn’t see these dramatic effects of acidification on fish behavior at all.
