Callendar's 1938 Figure

And via Ed Hawkins on Twitter, here's an interesting figure from Guy Callendar's 1938 scientific paper:

It's from "The Artificial Production of Carbon Dioxide and its Influence on Temperature," G. S. Callendar, Quarterly Journal of the Royal Meteorological Society v64 Issue 275 pp 223-240 (April 1938). [PDF]

Callendar also mentions the "well known" heat island effect, on page 235.

Note Callendar didn't attribute all the temperature rise to CO2. I don't see in his paper (though I haven't read it carefully) where he considered possible changes in solar irradiance (or, for that matter, a reduction in volcanic cooling that was part of the Little Ice Age). But those would be small, perhaps just a few hundreths of a degree (climate sensitivity to changes in solar radiance is small, about 0.1°C/(W/m2), for solar radiance measured at the top of the atmosphere; see the  IPCC 5AR).

1912 Newspaper Article on CO2 and Climate

Here's an interesting 1912 newspaper article from New Zealand:

The reference is: “Coal Consumption Affecting Climate,” Rodney and Otamatea Times, Waitemata and Kaipara Gazette, August 14, 1912.

Dear David Appell,

Know anyone who wants to learn more about climate science? We have a new offering of Climate Change: The Science open for registration at!  The course will start Nov 1st.  

If you have friends, colleagues, students, teachers, family, neighbors or anyone you think might enjoy this course, please feel free to pass along the link above.  Or maybe you would like to join us again, if you didn't have time to finish, or you're interested in earning a verified certificate.  We'd love to see you!

If you're active on twitter, facebook, or other social media, or if you are connected with listserves that might reach interested people, it'd be great if you could help spread the word. #climate1x, #climatechange, #mooc, and #edx are all useful tags.  Thanks for helping us connect with others!

Good luck to you with all your future climate-change-related activities!

The Dirt from Anthony Watts and His Blog

Warning: Don't invite Anthony Watts to your parties. He has a habit of leaving a lot of vomit on the floor. Or Eric Worrall, who has been nothing but wrong.

I predict Worrall's string of failures, shown below, won't change his inept and stubborn mind one bit.

"Everyone knows the Paris agreement was dead on arrival."
- Eric Worrall, WUWT 5/28/16

"It seems likely Lord Deben’s concerns about the Paris Climate Treaty are shared by other prominent green politicians."
- Eric Worrall, WUWT 3/9/16

"If the Paris Climate Agreement was already a joke, the Chinese electricity export plan is surely the punchline."
- Eric Worrall, WUWT 4/17/16

"Aussie academic David Holmes, of the University of Melbourne, suggests that Politicians are using the Paris Agreement to defuse climate concerns, by claiming Paris “solved” the climate crisis – and he’s not happy about it."
- Eric Worrall, WUWT 5/23/16

"The initial explosion of green Euphoria at the announcement of the COP21 climate agreement, is rapidly giving way to dismay, as various environmentalists and other expectant parties realise how feeble their climate “victory” really is."
- Eric Worrall, WUWT 12/15/15

"It’s been a few weeks since the U.N.’s Paris Climate Conference (COP21) ended. Mainstream media from around the globe praised the impotent agreement, as though anyone expects political promises to be kept. The COP21 agreement reminded me of the proverb A promise is a comfort for a fool."
- Bob Tisdale, WUWT 12/30/15

PS: Doesn't Anthony Watts ever contribute to his own blog anymore? Then what are his sponsors paying for?

Hayhoe Response to a Climate Denier

From a comment by Layzej, here's an instance of Kathleen Hayhoe smoothly dealing with a Texas city counciler...maniac...about his (quite trivial) objections to AGW.

Note the city councilor has a self-proclaimed "visceral" reaction to climate change -- not a rational reaction:

When Bob Dylan Defended Zionism

Don't let the title, "Neighborhood Bully," fool you.

Neighborhood Bully - Bob Dylan from Noehed on Vimeo.


Neighborhood Bully

Well, the neighborhood bully, he’s just one man
His enemies say he’s on their land
They got him outnumbered about a million to one
He got no place to escape to, no place to run
He’s the neighborhood bully

The neighborhood bully just lives to survive
He’s criticized and condemned for being alive
He’s not supposed to fight back, he’s supposed to have thick skin
He’s supposed to lay down and die when his door is kicked in
He’s the neighborhood bully

The neighborhood bully been driven out of every land
He’s wandered the earth an exiled man
Seen his family scattered, his people hounded and torn
He’s always on trial for just being born
He’s the neighborhood bully

Well, he knocked out a lynch mob, he was criticized
Old women condemned him, said he should apologize.
Then he destroyed a bomb factory, nobody was glad
The bombs were meant for him. He was supposed to feel bad
He’s the neighborhood bully

Well, the chances are against it and the odds are slim
That he’ll live by the rules that the world makes for him
’Cause there’s a noose at his neck and a gun at his back
And a license to kill him is given out to every maniac
He’s the neighborhood bully

He got no allies to really speak of
What he gets he must pay for, he don’t get it out of love
He buys obsolete weapons and he won’t be denied
But no one sends flesh and blood to fight by his side
He’s the neighborhood bully

Well, he’s surrounded by pacifists who all want peace
They pray for it nightly that the bloodshed must cease
Now, they wouldn’t hurt a fly. To hurt one they would weep
They lay and they wait for this bully to fall asleep
He’s the neighborhood bully

Every empire that’s enslaved him is gone
Egypt and Rome, even the great Babylon
He’s made a garden of paradise in the desert sand
In bed with nobody, under no one’s command
He’s the neighborhood bully

Now his holiest books have been trampled upon
No contract he signed was worth what it was written on
He took the crumbs of the world and he turned it into wealth
Took sickness and disease and he turned it into health
He’s the neighborhood bully

What’s anybody indebted to him for?
Nothin’, they say. He just likes to cause war
Pride and prejudice and superstition indeed
They wait for this bully like a dog waits to feed
He’s the neighborhood bully

What has he done to wear so many scars?
Does he change the course of rivers? Does he pollute the moon and stars?
Neighborhood bully, standing on the hill
Running out the clock, time standing still
Neighborhood bully

Steven Mosher, at Judith Curry's blog:
In short, there is PLENTY of ROOM within the climate science to hold extreme views, both about the science and policy. However,
there is no room for the luncacies of unicorns, for sun nuts, fo folks who dont get chaos, for radiative physics deniers, because you cant hold those views and actually Do science. you can do blogs and blog comments.. but that is about it
