An Ice Age was Predicted in the 1970s

Skeptics say that many scientists in the 1970s predicted an ice age. By saying this, they hope to create the impression that scientists are as wrong today as they were back then.

In the thirty years leading up to the 1970s, available temperature recordings indicated a very slight cooling trend. Also, air pollution from fossil fuel burning was thought to have been reflecting sunlight, thus cooling off the earth. As a result, a few scientists suggested that the current warm period after the last ice age could end, which might result in the Earth plunging into a new ice age over the next few centuries.

The media picked up on this and, a long list of local papers, weekly magazines, and television reports trumpeted reports of a coming ice age.

At the same time, however, a much greater number of scientists published contradicting studies. Their papers showed that the growing amount of greenhouse gases that humans were putting into the atmosphere would cause much greater warming – warming that would exert a much greater influence on global temperatures than any possible natural effects.

Scientists are Faking Global Warming Because of the Money They Make from Government

Typical of the slander that Skeptics like to indulge in is the claim that scientists are making up global warming simply to earn a salary and get funding from the government. Other than the slanderous arrogance such an accusation is based on there is a logical flaw in it.

There is a wide assortment of scientists and other professionals who are either directly employed by the government or receive research grants such as nuclear physicists, astronomers, medical personnel, chemists, biologists, etc. Are we supposed to assume that their respective fields are fraudulent just because they have a salary? Are we supposed to believe that the moon landing was faked just because NASA received billions of dollars and their scientists, engineers, and technicians had good salaries?

Skeptics never answer those questions.

It is Colder During Winter in the United States and Elsewhere

Skeptics like to point out what is happening, in limited portions of the world, as if the same thing was happening all over the world. It helps to see the big picture, though.

According to Skeptics, the fact that it gets cold in limited regions of the world is supposed to prove that there is no warming throughout the rest of the world. However, the temperature map below for February of 2019, shows it was as warm, warmer, or much warmer than 70 years ago throughout 97% of the world. About 3% of the earth was colder than past temperatures for the same time period. Most of the colder weather in that month occurred throughout most of the United States and Canada. However, temperatures were up to 11.8 degrees Celsius (21.24 degrees Fahrenheit) higher in most of Alaska, Siberia, and Russia.

The Climate Has Always Been Changing

Skeptics like to mention that Earth’s climate has always been changing and that there is thus no reason to worry about its changing today.

When the climate changed radically, millions of years ago, there were extinctions of plants and animals. It did not affect humanity because we did not exist back then.

When we did exist, as primitive hunter-gatherers, we could pick up our spears and gathering baskets and move to a different place if we did not like the weather in our local area. There were only a few million of us back then.

32,000 Scientists, 9,000 with PHDs, do not Believe in Global Warming

Skeptics like to mention that there is a multitude of scientists that do not believe in global warming. They refer to a petition put out by the late Dr. Frederick Seitz, a physicist by training. In this petition, it is claimed that there are 32,000 scientists who do not believe in human-caused global warming. Some background is necessary to understand this hoax.

In the late 1970s, Seitz became a consultant for the tobacco industry. He funneled funds into so-called research that claimed that there was no scientific evidence that smoking was dangerous to one’s health.

In 1984 Dr. Seitz founded the George C. Marshall Foundation, a conservative think tank that dedicated itself to rebutting several ecological issues. He argued that air pollution was not a threat to health and that the issue of global warming was fraudulent.

Those who Believe in Global Warming Changed the Phrase to “Climate Change” in Order to Deceive the Public

Skeptics accuse those who believe in global warming of having changed the phrase “global warming” to “climate change” in order to deceive the public. They claim that the change was made in order to explain any natural phenomenon other than mere warmth. They also state that this change was relatively recent, although they rarely say when it was made. By saying that it is recent, one could assume that they mean in the last decade at the most.

However, the phrase “climate change” or “climatic change” has been in the scientific literature for almost sixty-five years. With respects to human-caused climate change, the earliest known scientific papers using the phrase (In the titles) were published in 1956.

Below is a condensed list of scientific papers, from before the year 2000, with the phrase climate or climatic change in their titles:

Volcanoes Emit More Carbon Dioxide than Humans

According to many Skeptics, volcanoes release more Carbon Dioxide into the atmosphere than humans therefore, any human release of the gas is trivial and does not contribute to Global Warming. However, according to the United States Geological Survey (USGS), humans currently release 100 times more CO2 than volcanoes. They state:

Do the Earth’s volcanoes emit more CO2 than human activities? No.

…All studies to date of global volcanic carbon dioxide emissions indicate that present-day subaerial and submarine volcanoes release less than a percent of the carbon dioxide released currently by human activities.

Bolding theirs.

Also, in a detailed scientific paper by the American Geophysical Union, we read:

Which emits more carbon dioxide (CO2): Earth’s volcanoes or human activities? Research findings indicate unequivocally that the answer to this frequently asked question is human activities. However, most people, including some Earth scientists working in fields outside volcanology, are surprised by this answer. The climate change debate has revived and reinforced the belief, widespread among climate skeptics, that volcanoes emit more CO2 than human activities [Gerlach, 2010; Plimer, 2009]. – EOS, Transactions, American Geophysical Union, Volume 92, Number 24,  June 14, 2011 Pages 201-208
