“The fact is that we can’t account for the lack of warming at the moment and it is a travesty that we can’t”

– Kevin Trenberth  NCAR 2009

In 2015, satellites showed that the world had cooled since the beginning of the century.

This didn’t suit the agenda, so government scientists declared the “pause” to be invalid.

And Carl Mears at RSS complied by turning the cooling trend into a warming trend.

Wood for Trees: Interactive Graphs

Rather than changing the data, Carl Mears changed the interpretation of the data. After 2016 he removed the blue error range and used the upper bounds of the error rather than midrange of the error.

Note that after 1998, the observations are likely to be below the simulated values, indicating that the simulation as a whole are predicting too much warming.

He also changed the wording and misspelled satellite.

“Note that after 1998, the observations are likely to be in the lower part of the model distribution, indicating that there is a small discrepancy between the model predictions and the satelllite observations”

I predicted this would happen on March 27, 2015.

Look for the satellite data to be adjusted to bring it into compliance with the fully fraudulent surface temperatures. The Guardian is now working to discredit UAH, so it seems likely that RSS will soon be making big changes – to match the needs of the climate mafia. Bookmark this post.

I made this prediction because Ted Cruz used an RSS graph in a Senate hearing in March of 2015. Carl Mears at RSS then came under intense pressure to make his data match the surface temperature data.

My particular dataset (RSS tropospheric temperatures from MSU/AMSU satellites) show less warming than would be expected when compared to the surface temperatures. All datasets contain errors. In this case, I would trust the surface data a little more because the difference between the long term trends in the various surface datasets (NOAA, NASA GISS, HADCRUT, Berkeley etc) are closer to each other than the long term trends from the different satellite datasets. This suggests that the satellite datasets contain more “structural uncertainty” than the surface dataset.

Ted Cruz says satellite data show the globe isn’t warming

Roy Spencer at UAH made the same prediction on January 9, 2017

“I expect there will soon be a revised TLT product from RSS which shows enhanced warming, too.

Here’s what I’m predicting:

1) neither John Christy nor I will be asked to review the paper

2) it will quickly sail through peer review (our UAH V6 paper is still not in print nearly 1 year after submission)

3) it will have many authors, including climate model people and the usual model pundits (e.g. Santer), which will supposedly lend legitimacy to the new data adjustments.

Let’s see how many of my 3 predictions come true.

In 1992, the New York Times said there was no indication of global warming and that the MWP and LIA were global.

Warming? Tree Rings Say Not Yet

Lisa J. Graumlich, who examines the ring patterns of foxtail pine trees and western junipers in the Sierra Nevada, has compiled a detailed record of the year-to-year variation in temperature and precipitation over the last thousand years.

She has seen in the North American trees the feathery but unmistakable signatures of the Medieval Warm Period, a era from 1100 to 1375 A.D. when, according to European writers of the time and other sources, the climate was so balmy that wine grapes flourished in Britain and the Vikings farmed the now-frozen expanse of Greenland; and the Little Ice Age, a stretch of abnormally frigid weather lasting roughly from 1450 to 1850. A Crucial Question

“We can now see that these were global climate phenomena, not regional temperature variations,” she said. “The question is, how did we get those warmer temperatures during pre-industrial times, and what can we learn from those conditions about what is going on today?”

Ninety years ago, the New York Times reported unanimous consensus that Earth’s climate was controlled by the sun.

TimesMachine: July 2, 1931 – NYTimes.com

Now NASA reports 97% consensus that Earth’s climate is controlled by CO2.

“Multiple studies published in peer-reviewed scientific journals show that 97 percent or more of actively publishing climate scientists agree*: Climate-warming trends over the past century are extremely likely due to human activities.”

Scientific Consensus | Facts – Climate Change: Vital Signs of the Planet

I agree with them – the warming trends over the last century are primarily due to human activities – data tampering by organizations like NASA and NOAA. For example, over the past 20 years NASA has turned a 70 year cooling trend in the US from 1930 to 2000 into a warming trend. This is the 1999 version.

NASA 1999

And this is NASA’s current graph.

NASA 2021

Here is an animation showing how the data has been altered over the past 20 years.

The US temperature record is very important, because the vast majority of global stations in the NOAA GHCN database with a long term daily temperature record are located in the US.

station-counts-1891-1920-temp.png

In 1986, NASA’s James Hansen predicted 4-6 degrees warming for the US by the year 2020, and a huge increase in heatwaves.

“He said that with an expected doubling of atmospheric carbon dioxide by 2040, the number of days each year with temperatures over 80 degrees would rise from 35 to 85 in Washington, D.C., and Omaha, Neb.”

12 Jun 1986, Page 12 – The Evening Times at Newspapers.com

The actual temperature increase from 1958 to 2020 was about one degree.

The closest currently operational USHCN station to Omaha is at Logan, Iowa. The number of 90 degree days there peaked in 1894 and 1936 (83) and have been declining sharply ever since.

The closest currently operational USHCN station in Virginia to Washington DC is at Purcellville.  The number of 90 degree days there peaked in 1911 (96) and 1930 (89) and have been declining sharply ever since.

For the entire US, the frequency of 90 degree days has dropped sharply over the past century. Hansen got that exactly backwards.

In 1988, Hansen predicted a large increase in droughts.

“Dr. James E. Hansen, director of the Goddard Institute for Space Studies, who presented recent data compiled from computer models, said that predicted regional effects of global warming show that the chances of summer drought in the low and middle latitudes would be 1 in 3 by the year 2030, as against 1 in 20 in the 1950’s.”

FEROCIOUS STORMS AND DROUGHT SEEN – The New York Times

During the 1950’s the US was in drought most of the time, but droughts have been much less common over the past 60 years. Hansen also got that exactly backwards.

Climate at a Glance | National Centers for Environmental Information (NCEI)

One year after Hansen made his forecasts, scientists at NOAA set the record straight.

U.S. Data Since 1895 Fail To Show Warming Trend

“After examining climate data extending back nearly 100 years, a team of Government scientists has concluded that there has been no significant change in average temperatures or rainfall in the United States over that entire period.

While the nation’s weather in individual years or even for periods of years has been hotter or cooler and drier or wetter than in other periods, the new study shows that over the last century there has been no trend in one direction or another.

The study, made by scientists for the National Oceanic and Atmospheric Administration was published in the current issue of Geophysical Research Letters. It is based on temperature and precipitation readings taken at weather stations around the country from 1895 to 1987.”

U.S. Data Since 1895 Fail To Show Warming Trend – NYTimes.com

Ten years later, Hansen was upset that the US wasn’t warming as he predicted and the droughts weren’t occurring.

Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought. The drought of 1999 covered a smaller area than the 1988 drought, when the Mississippi almost dried up. And 1988 was a temporary inconvenience as compared with repeated droughts during the 1930s “Dust Bowl” that caused an exodus from the prairies, as chronicled in Steinbeck’s Grapes of Wrath.

The U.S. has warmed during the past century, but the warming hardly exceeds year-to-year variability. Indeed, in the U.S. the warmest decade was the 1930s and the warmest year was 1934.

NASA GISS: Science Briefs: Whither U.S. Climate?

So Hansen and NOAA got together and altered the US temperature record. NOAA now shows a warming trend from 1895 to 1987.

Climate at a Glance | National Centers for Environmental Information (NCEI)

In 2004, NOAA showed that they were altering US temperatures by 0.5F since the year 1900, with no further charges after 1990.

Wayback Machine

But now they are altering the data by 2.0F.

This graph compares the 2004 adjustments in blue, to the current adjustments in red.

And this graph normalizes the two sets of adjustments along the Y-Axis. There has been a huge increase in the amount of data tampering for years since 1990.

The NOAA adjustments trend very closely with the amount of carbon dioxide in the atmosphere, or at least they did until three years ago, when there was a huge increase in the amount of tampering.

NOAA fabricates missing data using a computer model, and last year almost 50% of their monthly US temperature data was fabricated.

This is the data for Brewton, Alabama. If the data is estimated rather than measured, it is marked with an “E” – All twelve months of 2020 were marked with an E.

ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/ushcn.tavg.latest.FLs.52j.tar.gz

The current data tampering is huge. The measured daily maximum temperature data for the US shows a strong cooling trend.

ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/v2.5/

But the adjusted data shows a strong warming trend.

The total adjustment to US average temperatures is more than two degrees Fahrenheit.

Plotted vs. CO2, it can be seen that until the last three years, the adjustments being made very closely tracked the increase in CO2. Data is being altered to match their theory.

All they actually did was replot the same graph which the US Government has had out there for several years.

Global Temperature and Carbon Dioxide | GlobalChange.gov

This graph directly contradicts what Tom Karl, longtime head of NOAA’s National Climatic Data Center said in 1989. He retired in 2017 just as President Trump took office.

“Analysis of warming since 1881 shows most of the increase in global temperature happened before 1919 — before the more re-cent sharp rise in the amount of carbon dioxide in the atmosphere, said Thomas Karl, of the National Oceanic and Atmospheric Administration’s National Climatic Data Center in Asheville, N.C. While global climate warmed overall since 1881, it actually cooled from 1921 to 1979, Karl said”

07 Dec 1989, Page 14 – Santa Cruz Sentinel at Newspapers.com

The warming from 1881-1919 has turned into cooling, and the cooling from 1921-1979 has turned into warming. When academics and government employees are willing to tamper with data – they can “prove” anything.

Global temperature his has been rewritten by government scientists over the past 30 years In 1974, the National Center For Atmospheric Research showed no net warming from 1870 to 1970.

14 Jul 1974, Page 1 – Lincoln Evening Journal at Newspapers.com

As of the year 2000, NASA showed no net warming from 1866 to 1979, with 1878 being the warmest year of that period.

But they now hide data before 1880, and show about 0.7C warming prior to 1980

https://data.giss.nasa.gov/gistemp/history/output/met_used.zip

This animation shows how they have altered the data

NASA GISS v4 shows more than 2C warming over land since 1880.

A different version of the same V4 graph also shows about 1.6C warming over land since 1880. This graph used to be linked to from their website, but I can no longer find any links. However the graph is still present on their website.

graph.png (1130×600)

The red lines in both of the graphs above should be identical, but they aren’t. Here is an animation showing how they are altering the land data in the new graph vs. the old graph. They have increased recent temperatures by about 0.3C and cooled past temperatures by about the same amount.

In 2001, NASA published the same graph showing half as much warming from 1880 to 2000.

2001: Fig.A.ps

This animation cycles through how NASA has altered the data over the past 20 years to greatly increase warming.

Let’s look now at why the data is being altered. In 1990, the IPCC showed no indication of man-made global warming and that current temperatures were just about average for the past thousand years.

In 1992, the New York Times said there was no indication of global warming and that the MWP and LIA were global.

Al Gore was elected VP in 1992, and he was determined to change things.

“any scientist who studied the Antarctic ice cores and did not consider global warming an immediate “crisis” was being “unethical.”

• Al Gore 1990

12 Aug 1990, Page 102 – The Indianapolis Star at Newspapers.com

He misinterpreted Antarctic ice core graphs to show CO2 drove ocean temperature rather than the opposite. Under his model, a 100 PPM change in CO2 caused a 10C swing in temperature.

New Antarctic Ice Core Data

If that was the case, the 7,000 PPM of the Cambrian Era would have produced Antarctic temperatures of 700C.

Science went out the window in 1992, and in 1993 my good friend Dr. Bill Gray – who was considered the world’s leading tropical meteorologist and the inventor of modern hurricane forecasting – received a phone call from VP Gore requesting his attendance at a global warming meeting Gore was having. Bill said he “would be happy to attend but was not a believer in Gore’s global warming apocalypse theories.” Dr. Gray immediately got his finding cut off and never received another penny from the government. Bill passed away five years ago this week and largely self-funded his research and his graduate students’ research from 1993 to 2016.

Everyone in the climate science community became aware that ongoing funding depended on towing the global warming line. Here he is with his Al Gore $8 bill.

Bill never gave an inch to climate fraudsters even when attacked by Judith Curry and her husband Peter Webster.

“CSU’s William Gray, told a U.S. Senate hearing last month that talk of global warming is “bogus science and media hype” driven by “scientists who were willing to bend their objectivity to obtain government grants.”

08 Oct 2005, Page 9 – The Palm Beach Post at Newspapers.com

When Bill passed away five years ago, even the climate alarmists at Weather Underground acknowledged his tremendous accomplishments, though they have since deleted this post.

But climate science became hopelessly corrupt as soon as Al Gore took office. He was under constant attack for telling the truth and thus threatening university funding.

By 1995, climate science and climate journalism was hopelessly corrupt.

“In 1995, I published a short paper in the academic journal Science. In that study, I reviewed how borehole temperature data recorded a warming of about one degree Celsius in North America over the last 100 to 150 years. The week the article appeared, I was contacted by a reporter for National Public Radio. He offered to interview me, but only if I would state that the warming was due to human activity. When I refused to do so, he hung up on me.”

“I had another interesting experience around the time my paper in Science was published. I received an astonishing email from a major researcher in the area of climate change. He said, “We have to get rid of the Medieval Warm Period.”

“it would be foolish to establish national energy policy on the basis of misinformation and irrational hysteria.”

• Dr David Deming

U.S. Senate Committee on Environment and Public Works

And three years later, Michael Mann hid the decline and made the Medieval Warm Period, Little Ice Age and post-1940 cooling disappear. He replaced the proxy data which showed cooling after 1940 with fake global temperature data from NASA and NOAA.

The United States temperature record is particularly important, because the vast majority of high quality long-term temperature data around the world are in the US.

The hockey stick of data tampering is being done precisely to match the increase in CO2 – which is the same story as is being done with the global temperature record.

So why is this being done? Apparently a decision was made decades ago by people who wanted to shut down the US energy supply to link CO2 and climate. Now that that has been done, Joe Biden is actually shutting down the US energy supply.

White House Considering Nearly Doubling Obama’s Climate Vow – Bloomberg

A lot of people froze to death in Texas during February because the state chose to rely on green energy.

The same thing would have happened in Colorado, but they had other more responsible states like Wyoming to provide their electricity for them. We had our coldest late winter day on record on Valentines Day in Cheyenne. Wyoming when the temperature never got above -7F (-22C.) This is what the Rawhide Coal Fired Power Plant and solar panels looked like across the border in Colorado. The state is panning on shutting down the coal plant in the next few years, despite the fact that most of Northern Colorado was depending on it for their survival.

“In recent years, PRPA has shifted more of its energy load to renewable sources, and it plans to reach 100% non-carbon generation by 2030

the intense cold at PRPA’s wind farms in Wyoming forced operators to shut them down. When ice builds on the windmill blades, it creates an imbalance that can damage the turbines, Roalstad said. As it turned out, the wind wasn’t blowing there anyway, so wind farm shutdowns had little impact. Solar resources were also of little to no help because the solar panels were covered with snow. The cold and limited sunshine kept the snow from melting.

Roalstad said that left the utility with two alternatives, and it used both. It bought power from neighboring utilities that might have had some to spare, and it asked consumers to reduce use.

The solution to situations such as this past weekend and what could occur in future years as PRPA and other utilities shut down coal-fired plants will be tapping into larger networks.”

Colorado is planning on being bailed out of their irresponsible behavior by Wyoming and Nebraska, but a national mandate from the White House would cause almost everyone to freeze to death next time this happens.

President Trump has understood what is going on for many years, which was one of the reasons for the coup against him and the across the board conspiracy by the press and social media to censor him.

Excess Deaths Associated with COVID-19

On hundred years ago, Scientific American relied on empirical data. Based on experimental evidence and hundreds of millions of years of earth history, they published this article explaining why increased atmospheric CO2 levels would benefit agriculture.

“Fertilizing the air with carbon dioxide to promote plant growth

ONE of the principal constituents making up the body of a plant is carbon, representing about one-half of its organic substance. The opinion that this carbon is derived from the soil has long been abandoned, modern investigation having shown atmospheric carbonic acid to be absorbed by means 0f the chlorophyll 0r green matter of the leaves and decomposed into its elements, the carbon, in conjunction with the root sap and atmospheric m0isture, being worked into organic compounds.

Whereas atmospheric air at present is relatively poor in carb0nic acid, of which it contains only about .03 per cent, at an early period in the development of our planet, when this was covered with the luxuriant forests our coal deposits are derived from, it comprised incomparably greater quantities of this gas. This fact suggested the idea of heightening the fertility of the soil by increasing its carbonic acid content and thus producing conditions resembling those of antediluvian ages.”

This view has been confirmed by lots more empirical data since the 1920 article.

Carbon Dioxide Fertilization Greening Earth, Study Finds | NASA

Crop Yields – Our World in Data

But now Scientific American no longer relies on evidence, and instead promotes baseless speculation by people whom they call “experts.”

Climate change’s negative effects on plants will likely outweigh any gains from elevated atmospheric carbon dioxide levels

many skeptics also fail to mention the potentially most harmful outcome of rising atmospheric CO2 on vegetation: climate change itself. Its negative consequences—such as drought and heat stress—would likely overwhelm any direct benefits that rising CO2 might offer plant life.
