Friday Funny: Chemtrails theory gets shot down by science

Watts Up With That?

Surveyed scientists debunk chemtrails conspiracy theory

Irvine, Calif., Aug. 12, 2016 – The world’s leading atmospheric scientists overwhelmingly deny the existence of a secret, elite-driven plot to release harmful chemicals into the air from high-flying aircraft, according to the first peer-reviewed journal paper to address the “chemtrails” conspiracy theory.

Researchers from the University of California, Irvine, the Carnegie Institution for Science and the nonprofit Near Zero organization asked 77 atmospheric chemists and geochemists if they had come across evidence of such a large-scale spraying program, and 76 responded that they had not. The survey results were published Wednesday in Environmental Research Letters.

Heat from aircraft engines produces condensation trails that can be clearly seen from the ground. A small but vocal segment…

John Christy Climate Video

Watts Up With That?

Guest essay by Eric Worrall

h/t JoNova – The following is a video presentation by John Christy from 2015 (published a few days ago), in which Christy uses his tremendous communication skills to help a non-specialist audience understand what is wrong with climate models, and the terrible moral downside of attempting to restrict CO2 emissions.

John Christy is the Alabama State Climatologist and a climate scientist with the University of Alabama. In 1991 he received the NASA Medal for Exceptional Scientific Achievement for his contribution to global temperature monitoring. In 1996 he received a special award from the American Meteorology Society.

One of the most interesting parts of the video is the Q&A section at the end of the video, as Christy answers questions and clarifies issues for intelligent students who have been fed a lot of nonsense about climate change.

My favourite question and answer;

On Earth Day, shots fired at building housing leading climate skeptic scientists

Watts Up With That?

Via email from Dr. Roy Spencer:

Shots fired at Christy/Spencer building

FYI, apparently sometime after a March for Science went past our building at UAH, 7 shots were fired and hit the floor John Christy is on. (I’m in a different part of the same building). No witnesses. I’m assuming late night Saturday or Sunday.

It seems pretty obvious this was a message being sent. If fired from a pistol, all shots hitting the same floor seems to suggest deliberate aim.

I doubt any media have covered it yet. I doubt the police have even written a report yet. From what I’ve heard, it sounds like the police believe the shots were fired from a passing car, and some shell casings were recovered, as well as fragments of bullets inside the building. You can quote me.

The office of the state climatologist (Dr. John Christy) is in building 7

Heads I Win, Tails You Lose; Hansen Used to Argue Less Greenhouse Gas Would Cause Warming

Why I decided not to take Kenji to the DC ‘March for Science’

Watts Up With That?

From the refund is due to his supporters department…

Back on January 30th I posted this:

Help send Kenji to the “Scientists March on Washington” event!

From the “all’s fair in love, war, and climate science” department comes this opportunity.

On Facebook, Dr. Roy Spencer made a comment related to a post on the original website calling for scientists to “March on Washington” to…

…take a stand for science in politics. Slashing funding and restricting scientists from communicating their findings (from tax-funded research!) with the public is absurd and cannot be allowed to stand as policy.

They add (bold mine):

Who can participate:

“Anyone who believes in empirical science. That’s it. That’s the only requirement. We will both have a diversity committee and a diverse steering committee that represents people of many backgrounds and identities. Science is done by POC, women, immigrants, LGBTQ, indigenous people, people of all beliefs and…

Vox: Telling Parents They’re Hurting Sick Children Maximises Climate Compliance

Watts Up With That?

Feeding people negative green messages.

Guest essay by Eric Worrall

According to Vox, one of the most influential emotional levers available to promote compliance with the climate conservation agenda is guilt about hurting children.

Why humans are so bad at thinking about climate change

How psychology can trick us into keeping Earth habitable.

Updated by Andy Murdock, University of California Apr 19, 2017, 9:10am EDT

When Per Espen Stoknes looked at polls going back to 1989 assessing the level of public concern about climate change in 39 different countries, he found a surprising pattern in the data.

“Incredibly enough, it shows that the more certain the science becomes, the less concern we find in richer Western democracies,” he said. “How can it be that with increasing level of urgency and certainty in the science, people get less concerned?”

…

To Stoknes, the dissonance problem might be an even bigger deal:…

New ‘Karl-buster’ paper confirms ‘the pause’, and climate models failure

Watts Up With That?

The “uncertainty monster” strikes again

We’ve been highly critical for some time of the paper in summer 2015 by Karl et al. that claimed “the pause” or hiatus went away once “properly adjusted” ocean surface temperature data was applied to the global surface temperature dataset. Virtually everyone in the climate skeptic community considers Karl et al. little more than a sleight of hand.

No matter, this paper published today in Nature Climate Change by Hedemann et al. not only confirms the existence of “the pause” in global temperature, but suggests a cause, saying “…the hiatus could also have been caused by internal variability in the top-of-atmosphere energy imbalance“.

That’s an important sentence, because it demonstrates that despite many claims to the contrary, CO2 induced forcing of the planetary temperature is not the control knob, and natural variability remains in force.

Also of note, see the offset as designated…

Pielke on Climate #1

The Climate Fix

I’ve decided to publish an occasional newsletter on climate and energy issues. It is not part of my day-to-day research or writing, which is focused on sports governance and science policy.  I’ve written a fair bit on the topics of climate and energy, including twobooks, and I may not have anything new or interesting to say. That’s OK, it’s just a blog.

A few things to say up front:

• If you don’t like what I write or don’t like me, then don’t read it. It’s OK, I don’t mind.
• If you do appreciate the perspective, consider the tip jar to your right.
• If you’d like to engage, consider a comment, a Tweet or an email. I am happy to discuss or debate.
• If you choose to call me names or lie about me, oh so common in discussing climate, then you will be blocked or ignored.
• We’ll…
