Scare Tactic: Earth turning into Venus! Refuted by Jim Nations

Climate Change leads to an Earth like Venus

A SCARE TACTIC

Neil-DeGrasse-Tyson-Children

Radio and podcast host astrophysicist Neil deGrasse Tyson makes a wild claim in a new video that can be found HERE on the Business Insider website.   Tyson proclaims, “Don’t worry, earth will survive climate change — we won’t!” Basically this statement is made because Tyson believes the earth will be turned into a planet much like Venus!   He also claims  that consensus makes something science when stating, “It’s science whether or not you believe it.”

Venus Talking Points by Jim Nations

Venus is closer to the Sun, so it should be hotter and it is. Venus receives almost twice as much solar energy as the Earth (inverse square law). It has a dense atmosphere of mostly CO2 and the surface pressure is 90 times higher than Earth (about 1300 pounds per square inch, roughly 3000 feet deep in an ocean on Earth). It is covered by bright clouds (high albedo). Its rotation and orbital parameters are different (see below), so it’s very slow rotation means the Sun-side has extended exposure to the incoming solar radiation.

Density of the Venusian atmosphere is one key issue to understand. 90 atmospheres of any gas means a very dense atmosphere around a planet. Would 90 atmospheres pressure of nitrogen (Earth’s major atmospheric constituent) trap heat as well as CO2?. No. Would a denser atmosphere on Earth trap more heat? Yes. Does the 400 parts million ratio (CO2 to total atmosphere volume) mean we’re headed towards Venus-like conditions? No.

The formation of both planets was very different and the current state of each planet is also very different.

Yes, CO2 traps heat. Gases can trap heat. What are the physics of CO2 at Venusian temp/pressure? CO2 takes on interesting characteristics as it is subjected to other than Earth-normal temp/pressure; ask anyone who is injecting CO2 for enhanced oil recovery. Plugging Venus conditions into a CO2 phase diagram is also part of the understanding.

Venus receives almost twice as much solar energy as the Earth. Mars, which is further way, receives 43% less solar flux than the Earth (inverse square law again).

10 Things About Venus

  1. Venus is smaller than Earth.
  2. Venus orbits at about 108 million km (67 million miles) or 0.72 AU from the Sun.
  3. A “day” on Venus is 243 Earth days (one full rotation). Venus completes a full orbit around the sun (one “year”) in 225 Earth days. Therefore, a day on Venus is longer than a year.
  4. Venus is a rocky planet with a cratered, volcanic landscape.
  5. Venus’ thick and toxic atmosphere is mostly carbon dioxide (CO2) and nitrogen (N2), with clouds of sulfuric acid (H2SO4) droplets.
  6. Venus has no moons.
  7. Venus has no rings.
  8. 40 spacecraft have explored Venus. Two Soviet landers in the 1980s lasted an hour and two hours, respectively. No other spacecraft have landed on Venus since. The Magellan mission in the early 1990s radar mapped 98 percent of the planet’s surface.
  9. No evidence for life has been found on Venus. The planet’s extreme high temperatures of 480 degrees Celsius (900 degrees Fahrenheit) make it seem an unlikely place for life.
  10. Venus rotates backwards (retrograde rotation) compared Earth. Therefore, the sun rises in the west and sets in the east.

Are we capable of turning Earth into Venus? No, and certainly not by adding incremental volumes of a trace gas – CO2 is now at 400 parts per million ratio (CO2 to total atmosphere) and has been much higher at times in the geologic past.

Is global climate warming change a political and financial scam? Yes – do the science and the financial math!

Questions to Ask

Why does Venus have so much CO2 in its atmosphere?

What events in its history cause it to have very slow retrograde rotation?

How does this very slow retrograde rotation affect its atmosphere and surface warming?

What other elements or chemical compounds, at 90 bar/atmospheres of pressure and density, would produce similar temperatures on Venus? Is CO2 the only compound that will do this? What are the physics of CO2 at Venusian temp/pressure – supercritical or ???

CO2 is now at 400 parts per million ratio (CO2 to total atmosphere volume) in Earth’s atmosphere; CO2 in the Venusian atmosphere is 970,000 parts per million of the total atmospheric gases. That’s about 2400 times more CO2. The percentage comparison is 0.04% to 97%.

It’s popular to say we might turn Earth into Venus because of the CO2 increase in Earth’s atmosphere from human activities – by what processes would this be possible? How long would that take?

What are the other gases in the Venusian atmosphere? What are the total atmospheric interactions given the pressure, temperature, circulation patterns and other variables?

Why isn’t Venus hotter? How much cooler is Mercury than Venus? Why is that?

Tyson needs to brush up on his history of science. Could it be that Non-Global Warming believers may some day be considered the mavericks of science when the hoax of global warming is understood for what it really is?

“It is our responsibility to leave the men of the future a free hand. In the impetuous youth of humanity, we can make grave errors that can stunt our growth for a long time. This we will do if we say we have the answers now; if we suppress all discussion, all criticism, saying, ‘This is it, boys, man is saved!’ and thus doom man for a long time to the chains of authority, confined to the limits of our present imagination. It has been done so many times before.”
― Richard P. Feynman, scientist, teacher, raconteur, and musician

One thought on “Scare Tactic: Earth turning into Venus! Refuted by Jim Nations

  1. Loved this article. Doctor deGrasse Tyson is the flavor of the month, but he has squandered an enormous amount of good will and credibility along with his own legacy, which will forever be tarnished when one hundred years go by, and the planet doesn’t burn. I used to REALLY like him, but now I see him as a fear pornographer: a shill for the Powers that Be, who want gasoline to be taxed the way cigarettes are in the United States. Lets hear him talk about real alternative energy solutions like LENR. We can have a clean environment, cheap energy and hey – no government power grabs necessary.
