It's time to pull the plug on our long-running CO2 experiment

Sou | 3:06 PM Go to the first of 22 comments. Add a comment
In the last 140 years or so, humans have added almost 1,000,000,000,000 tonnes of CO2 to the air (equivalent), or 1,000 billion tonnes. It would have been more except for oceans and land absorbing around half of it.

We are adding a lot of CO2 to the air


This leads me to talk about one of the many misconceptions thrown around by climate disinformers. Some deniers wrongly claim our CO2 emissions add little to atmospheric CO2. How they could ever think that is a mystery. It's not a secret that CO2 is a product of burning hydrocarbons. (Some are very confused, mixing up various numbers they've heard and tossing them back together in strange and wrong patchwork.)

Denier quote of the day: Why should I waste 24 minutes..(learning climate)

Sou | 11:16 PM Go to the first of 10 comments. Add a comment
The Twitter conversations I've written about before is giving more insight into the denial crowd. The bots and trolls are ramping up as the US election campaign gears up. (It goes on forever, doesn't it. The election is still more than a year away.) Among the bots there are some real people. One of them was happy to summarise the denier's stance.

I wouldn't devote even 24 minutes to learn science


Someone put up a chart purporting to show CO2 and temperature going back 4.5 billion years. I doubt the person tweeting it understood it. They said they got the picture from another denier called Nasif Nahle, who even put a copyright on it! It didn't matter. According to deniers, the tweet was from an acceptable denier so it must mean the greenhouse effect is a hoax.

Do your bit - help with a survey of climate blog readers

Sou | 11:38 PM Go to the first of 10 comments. Add a comment
How about helping out some researchers by taking a survey of climate blog readers. It's for a project being done jointly by researchers at Cambridge University and Wageningen University. The results will be made available to me and every one who completes the survey so, with luck, we all might learn something and HotWhopper could be better for it. And before you ask, it has ethics approval and yes, the survey is anonymous, responses confidential etc etc.

It'll only take up to about 10 minutes or so. If you start and get interrupted, I'm told you can save where you're up to and finish it later.

So don't hold back - go for it. It's in a very good cause.

Sou.

A short primer on global energy flows, for the twitter deniers

Sou | 2:56 PM Go to the first of 35 comments. Add a comment
Energy balancing when no forcing
There have been two or three people on the climate denial conversation on Twitter who cannot conceptualise global energy flows. Remember, almost all the deniers in this particular conversation are greenhouse effect deniers who don't "believe" physics and chemistry. Nonetheless they've discovered a wonky diagram in the deniosphere somewhere and have asked how it works. The short answer is, it doesn't. Not the way it's portrayed in their diagram.

Dr Kevin Trenberth has kindly allowed me to publish this updated global energy flow schematic, which is about to be published. (I'll post the doi when it is available.) Here it is, with an explanation below:

More twittery nonsense from climate disinformers: In fact, the world is heating up!

Sou | 1:00 PM Go to the first of 17 comments. Add a comment
There are one or two long-running denier conversations on Twitter. Here is another example of how they operate as illustrated by a tweeter called "StenchJudi".

Despite all the evidence showing the world is rapidly heating up, someone will tweet something outrageously wrong, such as "it's been cooling for twenty years". The only way they can rationalise such a ridiculous statement is by fudging the data, and claiming real observations are "fake".

The chart below shows how the global temperature has changed over the past twenty years, from 1999 to 2018:

There is no excuse for spreading disinformation about climate

Sou | 9:47 AM Go to the first of 2 comments. Add a comment
This is a personal note about how I consider hard-core deniers and disinformers to be as bad as the worst of the worst of humanity. They are comparable to Charles Manson, Timothy McVeigh and other horrors in that they want to harm people and take pleasure in the thought of civilisation destroying itself.

There is no excuse for anyone these days to doubt climate change or to not accept that we are causing it. In simple terms which everyone should know by now, we are burning more fossil fuel and adding more greenhouse gases to the air. This results in less energy going to space than is coming in from the sun. Our planet is heating up. Ice is melting, seas are rising, storms are more intense and heat waves are hotter. This is killing people, reducing our capacity to grow food, and causing a great deal of harm already. It will get worse before it gets better.

If a serial climate disinformer doesn't like being compared to mass murderers, then they should ask themselves why they are working so hard to bring about death and destruction. Or, they can change their behaviour and stop acting as if they want to. (Today there was a very unpleasant denier who objected to this comparison. He is a long term disinformer about climate change and has now been banned from this blog, so you won't see his comments or my response.) [Update: That particular disinformer just sent a comment to let me know he and his hard-core denier bloggers follow in the footsteps of "Hitler, Stalin, Mao and Pol Pot...", or words to that effect.]

Just wanted to put that out there.

Climate strike in Albury, Australia

Sou | 5:44 PM Go to the first of 8 comments. Add a comment
There are climate strikes all around the world in a wonderful display of unity and hope, tinged with hopelessness. In Albury, there were school students, infants, and adults of all ages and from all walks of life. The day was sunny and, as if it was sending a message, was the warmest day of September so far, recording 24.9 C (77F) at 2:30 pm, which is around 7 C above the average maximum for the month.

The students were an inspiration. They were knowledgeable and committed to taking Australians to task for not addressing climate change. The crowd was enthusiastic and supportive. After the event, you'd not know hundreds of people had assembled there - the lawns were probably more spotless after the event than before.

Denier twittery weirdness, with CO2 is a very cold gas

Sou | 8:41 PM Go to the first of 22 comments. Add a comment
CO2 sublimation
Over the last few days I've been spending some time on a long-running denier thread on Twitter. It was an opportunity to interact with the types you see at the climate conspiracy blog WUWT, but in an environment where it's much less likely anyone will be banned for posting science.

This article is to let you know about some of what I've learned about denier twitterers, with a new "theory" as a bonus.

Deniers yearn for attention from sciency types


One thing struck me above everything else. Fake sceptics are starved for attention.

As soon as a science type enters a room full of deniers, they get pounced on. Anyone who's followed comments at WUWT would have noticed the same thing. (Anthony Watts, the owner of WUWT, himself has demonstrated a yearning for recognition from scientists. That he can't get the type of recognition he wants has been a source of frustration to him.)

We need to save the Amazon, but not for the sake of oxygen

Sou | 2:13 AM Go to the first of 7 comments. Add a comment
There's been a crazy meme circulating in the media about oxygen. Let's fix that.

To their credit, quite a number of media outlets have been writing about the apparent reversal of the decline in the destruction of the Amazon rainforests.

Okay, that was a mouthful. Back in past decades the Amazon rainforest was being destroyed at a phenomenal pace. Local people became concerned and eventually they were heard around the world. Finally there was an turnaround or, I should say, the rate of destruction slowed substantially. Now it's picking up again and this is a very bad thing.

The problem with many of the reports is that they include a phrase (sometimes a headline): "The Amazon is often referred to as the planet's lungs, producing 20% of the oxygen in the Earth's atmosphere". That's way wrong!

Wildly untruthful at WUWT - Tim Ball did not "win" anything

Sou | 1:27 AM Go to the first of 24 comments. Add a comment
Over at WUWT there's jubilation in the air over...nothing. Anthony Watts is falsely claiming that Tim Ball won a court case. In fact, what happened was Tim Ball got the Court to dismiss the lawsuit because of delay. There was no finding. Tim got a lucky break (so far) and the case was dismissed without any judgement. Professor Mann may (or might not) appeal. Tim's going to be disappointed that Mann won't pay his legal fees. (See update below.)

I'll let Michael Mann correct the fake news.
There have been some wildly untruthful claims about the recent dismissal of libel litigation against Tim Ball circulating on social media. Here is our statement:

The defendant Ball did not “win” the case. The Court did not find that any of Ball’s defenses were valid. The Court did not find that any of my claims were *not* valid.

The dismissal involved the alleged exercise of a discretion on the Court to dismiss a lawsuit for delay. I have an absolute right of appeal. My lawyers will be reviewing the judgment and we will make a decision within 30 days.

The provision in the Court’s order relating to costs does NOT mean that I will pay Ball’s legal fees.

This ruling absolutely does not involve any finding that Ball’s allegations were correct in fact or amounted to legitimate comment. In making his application based on delay, Ball effectively told the world he did not want a verdict on the real issues in the lawsuit.
-
UPDATE

The reason Tim Ball requested the court stop the case due to "delay" is because he says he's old and sick. He supported his request by claiming no-one listens to his ravings. No-one takes any notice of his defamatory words. The Alexa rating for his blog is low, he says. So he sees himself as an old, sick nobody (or so he claims to the court). A man who's lived a life of no consequence (except to Anthony Watts and his band of inconsequential conspiracy nutters). See here and here.
