Summary: The news has become stranger since the climate policy debate has decoupled from the IPCC. Ludicrous claims of certain doom and nightmarish futures splash across the headlines, seldom with rebuttals (climate scientists are complicit in their silence). This one-sided flow of “news” will shape public opinion slowly but surely, creating support for bold measures by President Clinton. Activists are panicking the public for political gain.
“I think looking at grief is quite appropriate, as I believe we are facing human extinction”

“The more immediate danger is runaway climate change. A rise in ocean temperatures will melt the ice caps and cause the release of large amounts of carbon dioxide from the ocean floor. Both effects could make our climate like that of Venus, with a temperature of 250 degrees.”
— Nobel laureate physicist Stephen Hawking on “Good morning Britain on NBC News’ U.K. news partner, ITV News in May 2016.
This was reported as “Earth DOOMED by climate change which could burn us alive, warns Stephen Hawking” by Sean Martin in The Daily Express, 31 May 2016.
We have heard this story before. The BBC hinted at it last year; Hawking has said it before. There is no support for this in the IPCC’s reports and little (perhaps none) in the peer-reviewed literature. There are papers clearly saying the opposite, such as “Low simulated radiation limit for runaway greenhouse climates” by Colin Goldblatt el al, Nature Geoscience, August 2013 — Gated. See the press release here. Excerpt…
“The so-called `hothouse’ climate of the Eocene is the most useful constraint for anthropogenic change. With the solar constant 1% less than today and a few thousand ppmv CO2, the mean temperature was 10 K warmer than today. With CO2 and temperature both higher then than we expect in the foreseeable future, this implies that an anthropogenic runaway greenhouse is unlikely.
“…As the solar constant increases with time, Earth’s future is analogous to Venus’s past. We expect a runaway greenhouse on Earth 1.5 billion years hence if water is the only greenhouse gas, or sooner if there are others.”
- Venus is closer to the Sun. Venus is aprox. 0.72 AU distant from the sun (72% of Earth’s), with a total solar irradiance (TSI) almost 2x that of Earth.
- Venus has a denser atmosphere. The pressure on Venus is 93x that of Earth, the equivalent of almost 1 kilometer under the ocean. This is probably the largest factor causing its high temperature.
- The clouds of Venus are mostly sulphuric acid (not water vapor) — a powerful greenhouse agent.
- The atmosphere of Venus has nearly 3000x more CO2 than Earth’s atmosphere. Venus is 96.5% CO2 by volume vs. 380 per million for Earth (0.038%). Goldblatt el al say that with CO2 at 30,000 ppm Earth would have “no stable temperate climate.” That would require burning 10x more than Earth’s estimated fossil fuel resources.
A bizarre, even fun example of our mad news media
“Humans? In 2300? At the rate we’re going odds are there WON’T be many of them and the ones that are there will be far too busy trying to survive to bother over history, other than to curse us.”
— Comment by Bruce J. at the website of Brad DeLong (Prof Economics, Berkeley).
Take a look at “When Did the End Begin?” by Robert Sullivan in New York Magazine — “A scientific debate that’s oddly amusing to entertain: At what point, exactly, did mankind irrevocably put the Earth on the road to ruin?” The title is irrelevant to the article, which discusses dating the point at which the “Anthropocene Era” began, if the designation is approved. That is, when human impacts are the predominate force shaping Earth. It does not imply the beginning of the End Times.
Sullivan gives us the real-world version of an incident in Berkeley Breathed’s great “Bloom County” comic strip. It is not funny when played out in real life.
Bedfellow: “Hello, Bloom Beacon! This is Senator Bedfellow! What’s with this headline? … There’s no story, just a headline!”
Milo: “Which headline?”
Bedfellow: “The big headline on the front page!” ‘BEDFELLOW: THE SECRET LIFE OF A WIFE-SWAPPING ATHEIST’”
Mile: “Oh, that’s just a typo.”
“There will be no successor civilization. … Our planet had ONE shot at building a sustainable industrial civilization, and we humans f***ed it up, big time.”
— Comment by Redwood Rhiadra at website of Brad DeLong (Prof Economics, Berkeley).
A battle consists of phases. Both sides muster their forces, seize advantageous positions. Victory comes to the side that breaks through their foe’s lines. Then begins the pursuit phase, as the losers are chased away or destroyed.
Climate alarmists have followed this formula in the climate public policy debate. They built commanding positions in academia, the news media, ngo’s (such as foundations and the major science professional associations), and the relevant government agencies. With the funding and power so gained, they attack — abandoning the scientists of the IPCC (once called the “gold standard of climate science). Their articles are cheered and echoed by scores of organizations. Dozens of glitzy (well-funded) websites staffed by professionals propagate their messages, as do a flood of books and films.
Now they use their commanding position to say almost anything, however bogus, which pushes their message of climate doom. This campaign will reshape public opinion. For more information see Why skeptics will lose the US climate policy debate.
