Evidence about the great glow bull warming swindle being real, the libz are calling naturally occurring events glow bull warming. H. Sterling Burnett...
It’s that time of year again! Summer, when things get hot and dry and certain seasonal extreme weather events naturally occur -- as do alarming claims about them. When hurricanes form during “hurricane season,” expect climate alarmists to claim human-caused climate change is creating them, even though hurricanes have always formed at this time of year (thus the existence of the term “hurricane season”).
When wildfires break out during “wildfire season,” scorching thousands of acres of mismanaged, overgrown forests, expect climate alarmists to claim human-caused climate change is causing them, even though wildfires have always been sparked at this time of year (thus the existence of the term “wildfire season”).
The third in the trifecta of weather-related horror stories we can expect to read about every summer is drought. Droughts are normal and natural. At any point in time, portions of the United States and the world suffer from a drought of some length and severity. The areas suffering from drought change in response to shifts in short- and long-term weather and oceanic patterns of varying scales that affect precipitation. But that a drought is occurring somewhere, sometime is almost a certainty.
Some regions of the world and places in the United States are more prone to drought than others, of course. Those same areas are also more prone to prolonged droughts of multiple months, years, and sometimes even decades or millennia. The western United States is one such area.
This year’s drought-scare climate hype season has begun. A recent Yahoo! News article promoted the false claim human-caused climate change is responsible for a “historic” drought in California and the western United States.
Back-to-back dry years in conjunction with above-average temperatures have exacerbated drought conditions across the American West, the National Oceanic and Atmospheric Administration said on its website,” notes Yahoo News. “The extent of the drought is unprecedented in recorded history…”
Data show “back-to-back” dry years are not unusual in California or the western United States, even in recorded history. Neither California nor the western United States is experiencing a mega-drought. The U.S. Environmental Protection Agency’s (EPA) resurrected Climate Change Indicator series mid-May post titled “Climate Change Indicators: Drought,” undermines Yahoo News’ “historic” drought fairy tale.
Average drought conditions across the nation have varied over time,” writes EPA. “The 1930s and 1950s saw the most widespread droughts, while the last 50 years have generally been wetter than average [see the figure below]. Over the entire period… the overall trend has been toward wetter conditions,” wrote EPA
EPA’s report confirms what other sources of data demonstrate. As reported in Climate at a Glance: Drought, for example, the U.S. National Oceanic and Atmospheric Administration reports America is currently undergoing its longest period in recorded history with less than 40 percent of the country experiencing “very dry” conditions. Also, the United States in 2017 -- and then again in 2019 -- registered its smallest percentage of land area experiencing drought. In California, for example, 2019 ranked among the state’s wettest years since official records have been kept.
Interestingly, Yahoo News excludes the western states of Colorado and Wyoming from its analysis. Perhaps that’s because had Yahoo News included data from these two states, it would have further undermined the claim that the drought in the American West was historic.
In less than six months, the area of Colorado experiencing some level of drought fell from 100 percent to less than 50 percent. The area of Colorado experiencing severe drought conditions or worse, declined from 93 percent of the state to approximately 35 percent at present.
By contrast, in June 2020, nearly 99 percent of Wyoming was drought-free. This has changed. At present, 24 percent of Wyoming is experiencing at least severe drought, still far below Yahoo News’ assertion that 72 percent of the western United States was suffering from a severe, multi-year drought.
Colorado and Wyoming’s precipitation records show how dramatically drought conditions can change in short periods. The lesson: drought comes and goes, lingering in some places longer than in others. Research conclusively demonstrates the current drought in the western United States is not historic in length or severity.
In the book The West Without Water, the authors note, “Prolonged droughts -- some of which lasted more than a century -- brought thriving civilizations, such as the ancestral Pueblo (Native Americans) of the Four Corners region, to starvation, migration, and finally collapse.” Indeed, research shows decade-long droughts happen once or twice a century in the western United States. What’s more, droughts lasting for multiple decadesoccur a few times each millennium.
To conclude, “back-to-back” years of drought are hardly uncommon, and don’t count as mega-droughts. Also, because mega-droughts in the western United States have lasted for decades and even centuries, it is impossible to attribute current drought conditions, barely two years old, to human-caused global warming.
Americans should know these facts. Especially as the mainstream media and radical climate alarmists bombard the public with reports claiming human-caused climate change is causing a historic mega-drought in the West and that conditions will become worse in the future unless Americans cede power to international climate experts and cease using fossil fuels. Unlike droughts, their arguments are all wet.

So, the last thing you read was climate change denial. You have, on occasion, admitted that the cause of climate change/global warming was the issue, not the fact that it was occurring: anthropomorphic or natural cycle.
Suppose there were data that indicated that our world is warming? There is, and it's abundant. Your sophist arguments are based on the manufactured data and won't even allow the natural cycle versus anthropomorphic cause discussion.
Cover your eyes, block your ears. Intentional ignorance.
This article was first published in August 2014, and it has been updated to include new research published since then. This article is one of a two-part series on past temperatures, including how warm the Earth has been “lately.”
Our 4.54-billion-year-old planet probably experienced its hottest temperatures in its earliest days, when it was still colliding with other rocky debris (planetesimals) careening around the solar system. The heat of these collisions would have kept Earth molten, with top-of-the-atmosphere temperatures upward of 3,600° Fahrenheit.
Even after those first scorching millennia, however, the planet has often been much warmer than it is now. One of the warmest times was during the geologic period known as the Neoproterozoic, between 600 and 800 million years ago. Conditions were also frequently sweltering between 500 million and 250 million years ago. And within the last 100 million years, two major heat spikes occurred: the Cretaceous Hot Greenhouse (about 92 million years ago), and the Paleocene-Eocene Thermal Maximum (about 56 million years ago).
History of hot
Temperature records from thermometers and weather stations exist only for a tiny portion of our planet's 4.54-billion-year-long life. By studying indirect clues—the chemical and structural signatures of rocks, fossils, and crystals, ocean sediments, fossilized reefs, tree rings, and ice cores—however, scientists can infer past temperatures.
None of these techniques help with the very early Earth. During the time known as the Hadean (yes, because it was like Hades), Earth’s collisions with other large planetesimals in our young solar system—including a Mars-sized one whose impact with Earth likely created the Moon—would have melted and vaporized most rock at the surface. Because no rocks on Earth have survived from so long ago, scientists have estimated early Earth conditions based on observations of the Moon and on astronomical models. Following the collision that spawned the Moon, the planet was estimated to have been around 2,300 Kelvin (3,680°F).
Even after collisions stopped, and the planet had tens of millions of years to cool, surface temperatures were likely more than 400° Fahrenheit. Zircon crystals from Australia, only about 150 million years younger than the Earth itself, hint that our planet may have cooled faster than scientists previously thought. Still, in its infancy, Earth would have experienced temperatures far higher than we humans could possibly survive.
But suppose we exclude the violent and scorching years when Earth first formed. When else has Earth’s surface sweltered?
Thawing the freezer
Between 600 and 800 million years ago—a period of time geologists call the Neoproterozoic—evidence suggests the Earth underwent an ice age so cold that ice sheets not only capped the polar latitudes, but may have extended all the way to sea level near the equator. Reflecting ever more sunlight back into space as they expanded, the ice sheets cooled the climate and reinforced their own growth. Obviously, the Earth didn’t remain stuck in the freezer, so how did the planet thaw?
Even while ice sheets covered more and more of Earth’s surface, tectonic plates continued to drift and collide, so volcanic activity also continued. Volcanoes emit the greenhouse gas carbon dioxide. In our current, mostly ice-free world, the natural weathering of silicate rock by rainfall consumes carbon dioxide over geologic time scales. During the frigid conditions of the Neoproterozoic, rainfall became rare. With volcanoes churning out carbon dioxide and little or no rainfall to weather rocks and consume the greenhouse gas, temperatures climbed.
What evidence do scientists have that all this actually happened some 700 million years ago? Some of the best evidence is "cap carbonates" lying directly over Neoproterozoic-age glacial deposits. Cap carbonates—layers of calcium-rich rock such as limestone—only form in warm water.
The fact that these thick, calcium-rich rock layers sat directly on top of rock deposits left behind by retreating glaciers indicate that temperatures rose significantly near the end of the Neoproterozoic, perhaps reaching a global average higher than 90° Fahrenheit. (Today's global average is lower than 60°F.)
The tropical Arctic
A Smithsonian Institution project has tried to reconstruct temperatures for the Phanerozoic Eon, or roughly the last half a billion years. Preliminary results released in 2019 showed warm temperatures dominating most of that time, with global temperatures repeatedly rising above 80°F and even 90°F—much too warm for ice sheets or perennial sea ice. About 250 million years ago, around the equator of the supercontinent Pangea, it was even too hot for peat swamps!
Geologists and paleontologists have found that, in the last 100 million years, global temperatures have peaked twice. One spike was the Cretaceous Hot Greenhouse roughly 92 million years ago, about 25 million years before Earth’s last dinosaurs went extinct. Widespread volcanic activity may have boosted atmospheric carbon dioxide. Temperatures were so high that champsosaurs (crocodile-like reptiles) lived as far north as the Canadian Arctic, and warm-temperature forests thrived near the South Pole.
Another hothouse period was the Paleocene-Eocene Thermal Maximum (PETM) about 55-56 million years ago. Though not quite as hot as the Cretaceous hothouse, the PETM brought rapidly rising temperatures. During much of the Paleocene and early Eocene, the poles were free of ice caps, and palm trees and crocodiles lived above the Arctic Circle.
During the PETM, the global mean temperature appears to have risen by as much as 5-8°C (9-14°F) to an average temperature as high as 73°F. (Again, today’s global average is shy of 60°F.) At roughly the same time, paleoclimate data like fossilized phytoplankton and ocean sediments record a massive release of carbon dioxide into the atmosphere, at least doubling or possibly even quadrupling the background concentrations.
It is still uncertain where all the carbon dioxide came from and what the exact sequence of events was. Scientists have considered the drying up of large inland seas, volcanic activity, thawing permafrost, release of methane from warming ocean sediments, huge wildfires, and even—briefly—a comet.
Like nothing we’ve ever seen
Earth’s hottest periods—the Hadean, the late Neoproterozoic, the Cretaceous Hot Greenhouse, the PETM—occurred before humans existed. Those ancient climates would have been like nothing our species has ever seen.
Modern human civilization, with its permanent agriculture and settlements, has developed over just the past 10,000 years or so. The period has generally been one of low temperatures and relative global (if not regional) climate stability. Compared to most of Earth’s history, today is unusually cold; we now live in what geologists call an interglacial—a period between glaciations of an ice age. But as greenhouse-gas emissions warm Earth’s climate, it's possible our planet has seen its last glaciation for a long time.

Currently the growing science thinking is that it is the Sun that is the main driver of all the other variables of atmosphere and climate. What control our worlds atmosphere is the sun. Any and everything that man does can be wiped out by the sun in the matter of a very short time. Our lives depend on the sun staying within a certain range, it not we are done. What man does is minor and has no real effect. |

Denialism by resident alarmist CroWalt Left notwithstanding...
If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman
June 14, 2021
As an addendum to my 2020 series of posts on the CO2 global warming hypothesis (here>, here</strong> and here), this post presents a further challenge to the hypothesis central to the belief that humans make a substantial contribution to climate change. The hypothesis is that observed global warming – currently about 1 degree Celsius (1.8 degrees Fahrenheit) since the preindustrial era – has been caused primarily by human emissions of CO2and other greenhouse gases into the atmosphere. SUA
The new challenge to the CO2 hypothesis is set out in a recent research paper by French geologist Pascal Richet. Richet claims, by reexamining previous analyses of an Antarctic ice core, that greenhouse gases such as CO2 and methane had only a minor effect on the earth’s climate over the past 423,000 years, and that the assumed forcing of climate by CO2 is incompatible with ice-core data. The paper is controversial, however, and the publisher is subjecting it to a post-publication review. Science
The much-analyzed ice core in question was drilled at the Russian Vostok station in East Antarctica. Past atmospheric CO2levels and surface temperatures are calculated from ice cores by measuring the air composition and the oxygen 18O to 16O isotopic ratio, respectively, in air bubbles trapped by the ice. The Vostok record, which covers the four most recent ice ages or glaciations as well as the current interglacial (Holocene), is depicted in the figure below. The CO2 level is represented by the upper set of graphs (below the insolation data), which shows the substantial drop in CO2 during an ice age; the associated drop in temperature ΔT is represented by the lower set of graphs. Under
It is seen that transitions from glacial to interglacial conditions are relatively sharp, while the ice ages themselves are punctuated by smaller warming and cooling episodes. And, though it’s hardly visible in the figure, the ice-age CO2 level closely mimics changes in temperature, but the CO2concentration lags behind – with CO2 going up or down after the corresponding temperature shift occurs. The lag is about 600 to 800 years. Attack
Most paleoclimatologists believe that CO2 lagged temperature during the ice ages because it takes several hundred years for CO2 to come out of, or get into, the world’s oceans, which is where the bulk of the CO2 on our planet is stored. The oceans can hold much more CO2 (and heat) than the atmosphere. Warm water holds less CO2 than cooler water, so the oceans release CO2 when the temperature rises, but take it in when the earth cools.
Richet noticed that the temperature peaks in the Vostok record are much narrower than the corresponding CO2 peaks. The full widths at half maximum, marked by thick horizontal bars in the figure above, range from about 7,000 to 16,000 years for the initial temperature peak in cycles II, III and IV, but from 14,000 to 23,000 years for the initial CO2 peak; cycle V can’t be analyzed because its start is missing from the data. All other peaks are also narrower for temperature than for CO2.
The author argues that CO2 can’t drive temperature since an effect can’t last for a shorter period of time than its cause. The fact that the peaks are systematically wider for CO2 than for temperature implies that the CO2 level responds to temperature changes, not the other way round. And for most of cycles II, III and IV, CO2 increases correspond to temperature decreases and vice versa.
Richet’s conclusion, if correct, would deal a deathblow to the CO2 global warming hypothesis. The reason has to do with the behavior of the temperature and CO2 level at the commencement and termination of ice ages.
Ice ages are believed to have ended (and begun) because of changes in the Earth’s orbit around the sun. After tens of thousands of years of bitter cold, the temperature suddenly took an upward turn. But according to the CO2 hypothesis, the melting of ice sheets and glaciers caused by the slight initial warming could not have continued, unless this temperature rise was amplified by positive feedbacks. These include CO2feedback, triggered by a surge in atmospheric CO2 as it escaped from the oceans.
The problem with this explanation is that it requires a similar chain of events, based on CO2 and other feedbacks, to have enhanced global cooling as the temperature fell at the beginning of an ice age. But, says Richet, “From the dual way in which feedback would work, temperature decreases and increases should be similar for the same concentrations of greenhouse gases, regardless of the residence times of these gases in the atmosphere.” The fact that temperature decreases don’t depend in any noticeable way on CO2 concentration in the figure above demonstrates that the synchronicity required by the feedback mechanism is absent.

Samantha Chang...
Democrats and their media lapdogs are rabidly hyping the bogus narrative that climate change is an imminent "existential threat" to mankind as part of a cynical move to promote left-wing agendas. That's the takeaway from a Fox News interview with physicist Steven Koonin, who offered scientific support to those who believe grifting climate alarmists are flippantly weaponizing this sham talking point to enrich and empower themselves.
"It’s a fiction of the media and the politicians who like to promote that notion," Koonin said on Fox Nation’s "Tucker Carlson Today." Lest anyone dismiss Koonin as "right-wing," it bears pointing that he was undersecretary for science in former President Barack Obama's Department of Energy. The theoretical physicist and engineering professor is currently the director of the Center for Urban Science and Progress at New York University.
Despite the nonstop environmental fearmongering from Democrats and the left-wing media, he said "human influences" are not responsible for natural disasters such as hurricanes and intermittent heatwaves, which are just as common today as they were in 1900. "The warmest temperatures have not gone up in the last 60 years," Koonin said.
Koonin scoffed at Biden administration officials such as Transportation Secretary Pete Buttigieg and jet-setting climate czar John Kerry, saying they mindlessly parrot the term "existential threat" when discussing the climate even though they don't understand what they're talking about. "I don't think the science says what … Secretary Pete thinks it says," he said. "In fact, I can guarantee you he's never read the science."
Koonin continued: "Fact, I can guarantee you that Sen. [Bernie] Sanders, President [Joe] Biden, Ambassador Kerry, [Energy] Secretary [Jennifer] Granholm have never read the science -- because you need to be a scientist in order to do that. And in fact, when you read it, there's very little in terms of extreme weather that has changed over the last many decades.
The physicist also berated the scientific community for not pushing back at clueless politicians and media that are promoting climate alarmism. Allowing these lies to metastasize in the public consciousness causes unnecessary panic and erodes the credibility of legitimate environmental scientists who don't endorse this mass hysteria.
"It is a failure of the scientific community not to stand up and say, ‘Guys, you know, you have over-egged the custard. You really need to be much more circumspect in how you talk about this,’" Koonin said. Environmental expert Patrick Moore, the co-founder of Greenpeace, echoed these sentiments when he asserted in February that there is “zero evidence” that we’re in the midst of a climate emergency.
Like Koonin and some other environmental experts, Moore torpedoed climate alarmism as pseudoscientific propaganda whose goal is to redistribute wealth and usher in a new world order. It is clear that the highly exaggerated claims … are not so much out of concern for endangered species as they are a front for a radical political, social and economic ‘transformation’ of our entire civilization,” Moore said during a 2019 congressional hearing.
There's some consensus within the scientific community that human activity has contributed to climate change. But what’s undetermined is the degree to which human actions accelerated it and whether “climate change” is an existential threat. And if so, is there anything realistically that we can do to prevent it?
“Most scientists do not believe human greenhouse gas emissions are a proven threat to the environment or to human well-being, despite a barrage of propaganda insisting otherwise coming from the environmental movement and echoed by its sycophants in the mainstream media,” the Heartland Institute, a public policy think tank, says in its summary page on the issue.
Earth has undergone five significant ice ages, according to History.com. Four occurred long before humans existed, thereby undermining the left-wing narrative that driving cars and using air conditioners fueled climate change. In 2019, a nonprofit think tank called the Competitive Enterprise Institute compiled a 38-page report chronicling the numerous false predictions made by Democrats and climate alarmists over the past 50 years.
Modern doomsayers have been predicting climate and environmental disaster since the 1960s,” the report asserted. “They continue to do so today. None of the apocalyptic predictions with due dates as of today have come true.” The conclusion of the five decades of failed apocalyptic predictions was that the false prophets constantly warning about imminent existential threats were doing so to push partisan political agendas.
Just as they did with the race card, Democrats have weaponized “climate change” to stoke public panic in order to push socialist policies that have little to do with the environment and everything to do with raising your taxes and taking money from one group to give to another.
You would think after 5 decades of a failed strategy, that these libz would just give up on this monumental failure of a...
