Gavin Schmidt and Reference Period “Trickery”

Climate Audit

In the past few weeks, I’ve been re-examining the long-standing dispute over the discrepancy between models and observations in the tropical troposphere.  My interest was prompted in part by Gavin Schmidt’s recent attack on a graphic used by John Christy in numerous presentations (see recent discussion here by Judy Curry).   christy_comparison_2015Schmidt made the sort of offensive allegations that he makes far too often:

@curryja use of Christy’s misleading graph instead is the sign of partisan not a scientist. YMMV. tweet;

@curryja Hey, if you think it’s fine to hide uncertainties, error bars & exaggerate differences to make political points, go right ahead.  tweet.

As a result, Curry decided not to use Christy’s graphic in her recent presentation to a congressional committee.  In today’s post, I’ll examine the validity (or lack) of Schmidt’s critique.

Schmidt’s primary dispute, as best as I can understand it, was about…

CSIRO: 97% Gloomy Religion

CSIRO boss defends shake-up, says politics of climate ‘more like religion than science’

Dr Marshall said he understood the concerns – from both abroad and his staff internally.

“I don’t blame our scientists for crying out – they’re passionate about what they do,” he said.

“When a scientist has spent 20 or 30 years working in a particular area, they love it, that’s what gets them out of bed in the morning – they’re not going to want to change.


Wait. What?

“they love it, that’s what gets them out of the bed in the morning”


What sort of person loves this?:

When the End of Human Civilization Is Your Day Job
Among many climate scientists, gloom has set in.

Things are worse than we think, but they can’t really talk about it.


Every Day.

Eternally Gloomy because their apocalypse fails to materialise.

Can’t talk about it.

Send money.

Worse Apocalypse. Ever.

CSIRO: Scientist dump 97%

Even Frasier would see the irony …

Scientists, whose job it is to predict the future, fail to predict their own future:

4 February, 2016:

The head of the CSIRO, Larry Marshall, said in a letter to staff on Thursday that the government’s science agency’s job had been “to prove climate change”.

“That question has been answered,” he told staff.

Continuing to do climate research would be akin to resting “on our laurels” and would be the “path to mediocrity”.

Cue the 97% scientists who squawked  the mantra “the science is settled” now squeal “the science is not settled“:

Will Steffen, October 2013:

”We’d like to see a debate in this country that gets beyond these futile arguments about the science, which have been settled for decades in the scientific literature, and get on with the real debate about what is really the best way forward with dealing with the problem.

”So, yes, it is frustrating having to go back again and again and again and talk about what the science actually says.”

Flashback 2002: CO2 allegedly made the Harbin ice sculptures “sweaty”.

Jan 8, 2008 

“Average annual temperatures in the city perched on the edge of Siberia hit 6.6 degrees Celsius (44 Fahrenheit) last year, the highest average since records began, and the ice sculptures are feeling the heat.

“In the beginning of December 2002, ice lanterns in Harbin melted right after they were sculpted. What came out of the work was sweaty ice sculptures,” Yin Xuemian, senior meteorologist at the Heilongjiang Observatory, told Reuters.

Problems got worse in 2006.”

Global Warming: Murder in the name of

An editorial at is years too late:

Murder: An Acceptable Means For Fighting Global Warming?

Activists accused of blocking a rail line were acquitted last week of obstruction.
Jurors apparently felt their actions were justifiable because they were trying to save the climate.
How far will this be allowed to go?

Here is a news flash for the editor:

UK aid helps to fund forced sterilisation of India’s poor

“Court documents filed in India earlier this month claim that many victims have been left in pain, with little or no aftercare.
Across the country, there have been numerous reports of deaths and of pregnant women suffering miscarriages after being selected for sterilisation without being warned that they would lose their unborn babies.
Yet a working paper published by the UK’s Department for International Development in 2010 cited the need to fight climate change as one of the key reasons for pressing ahead with such programmes.
The document argued that reducing population numbers would cut greenhouse gases …”

Global Warming Heroes or Zeroes?

I don’t want to even think about what the weather would be like if some Australians didn’t ride bicycles:

Cyclists are climate-change heroes but we are often treated as villains

“So there I was, separated from my partner and our three-year-old, standing with my bike, five heavy panniers, two tents, beach ball and guitar all strapped on, and, dare I say it, a stowaway.

Zero, our wiry-haired Jack Russell, is as significant a family member as anyone else in our little tribe. When we go travelling he always comes.

So why do we chose to travel like this?

But we want to make a difference, we have pretty much gone fossil-fuel cold turkey, and breaking rules has become part of our reality.”

One man’s reality is another mans unreality:

How family planning could be part of the answer to climate change

“You’ve changed your lightbulbs, you recycle, you’ve retrofitted your house, cycle when you can, and drive an electric car when you can’t.

You’re doing your bit to reduce your carbon emissions and prevent dangerous climate change.

But if you have two children, your legacy of carbon emissions could be 40-times higher than those you saved through lifestyle changes.”

Pet dogs as bad for planet as driving 4x4s, book claims

“Owners should consider doing without, downsizing or even eating their pets to help save the planet, according to a new book.

A medium-sized dog has the same impact as a Toyota Land Cruiser driven 6,000 miles a year, while a cat is equivalent to a Volkswagen Golf.”
