Denier twittery weirdness, with CO2 is a very cold gas

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 21 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.

If global surface temperature keeps rising at the current rate

Sou | 12:45 AM Go to the first of 7 comments. Add a comment
I'm not going to go full-on with some wide-ranging projections, this article is mainly about temperature. It was prompted by something silly written in an article at WUWT, by a random blogger who goes by the name of Larry Kummer.

Larry was musing about how fast it's warming. He nicely put up some facts, based on the NOAA temperature report but then showed the extent of his ignorance about climate change.

Desperate Deniers head for the clouds at WUWT

Sou | 3:23 PM Go to the first of 19 comments. Add a comment
My last article was a report of the latest surface temperature, from NASA. This one is about the lower troposphere changes - and denier dross from WUWT.

I've not spent much time at WUWT in recent months (or here at HotWhopper). The articles there have changed a bit since Anthony Watts took time off. There are a lot more political articles and fewer science articles. Charles the Moderator is in charge but doesn't have a lot of people to write - it's mainly childish Eric Worrall and a petrol-head called David Middleton. Most of the regular WUWT contributors from days gone by have disappeared (justthefacts, Bob Tisdale, Tim Ball etc., and Anthony Watts himself.)

These days, when Charles copies and pastes a press release about a scientific publication, he doesn't have to add the dog-whistling word "claim" at the front of the headline. WUWT readers are now very well trained and understand that if there's a scientific press release it means they are expected to add comments along the lines of "climate science is a hoax" (repeated 100 times or they are put in detention).

Hottest July and hottest month on record

Sou | 5:23 AM Go to the first of 30 comments. Add a comment
Summary: July 2019 was the hottest July on record and the equal hottest month on record. The 12 month period to July 2019 was the third hottest  such period on record.

According to GISS NASA, the average global surface temperature anomaly for July was 0.93 °C, which is 0.08 °C warmer than the previous hottest - July 2016.

Below is a chart of the average of 12 months to July each year. 2019 averaged 0.93 °C above the 1951-1980 mean, which was 0.12 °C cooler than the 12 months to July 2016.

This makes it the third hottest August to July 12 month period on record after 2016 and 2017.

IPCC Climate Change and Land - on food waste (and diet)

Sou | 9:13 PM Go to the first of 9 comments. Add a comment
Local vineyard
The most recent IPCC report, Climate Change and Land, was released last week.  The report covers a lot of ground (pardon the pun), including desertification, land degradation and food security.

I've been reading it, slowly. (It's no easier to read than any other IPCC report.) I've also seen a few articles that came out at the same time or shortly after its release.

Over time, I hope to cover more aspects of the IPCC report. Today I'll just comment on one issue that's been picked up around the traps, and that's food waste, and I'll make passing mention of diet. The food waste issue has been raised a few times since the report was released and, in my view, the articles range from fairly good to overly simplified to plain wrong. I'm not about to give easy answers or point to specific articles, just offer some food for thought (don't waste it).

Don't kill climate deadlines

Sou | 1:14 AM Go to the first of 29 comments. Add a comment
I'm taking some time out from my time out to write about deadlines. Oddly, very oddly IMO, there are objections to deadlines coming from a number of quarters. Deadlines are essential for us to combat climate change. It should be obvious and it seems silly to have to argue the point. But it seems I do.

We are on a collision course with nature, a collision course of our own making. We need to change course. We've started, but we've not done nearly enough yet to prevent major damage. We need to do more and we need to keep planning how and set timelines and targets, otherwise known as deadlines. Then we have to carry out those plans.

We've missed opportunities and are suffering the consequences, with places running out of water, suffering unprecedented heat waves, drought and floods. That's with just over 1 C of warming. Urgent action is needed to avoid much greater harm.

Want to stay below 1.5 C? Then we'll need to cut emissions by 45% by 2030 and to net zero by 2050. Willing to accept an overshoot or let the world get a bit hotter? Then adjust those numbers accordingly and prepare to pay even more for disaster recovery and adaptation.

Australians choose a rocky road

Sou | 9:49 AM Go to the first of 45 comments. Add a comment
Australians voted yesterday and, against the odds, decided to opt for speeding up climate change and destroying our wonderful land.

We had two main choices: a plan to invest in a "fair go" future setting the tone for the difficult years ahead; and a choice to defer that investment, wreck our agriculture, and transfer more wealth to the high end of town.

Australians chose the latter.

Don't get me wrong. The Australian Labor Party is far from perfect. It, too, doesn't fully appreciate the damage we are doing to our world. Nor does it fully appreciate the fragility of Australia and the dangers we face. Nevertheless, overall the choices it offered were a lesser evil than those of the Liberal National coalition.

The question is, should Australians and the world suffer because a slim majority voted against the well-being of farmers, fishers, foresters and everyone in our towns and cities? Should we stand by and allow the destruction of our rivers, grasslands, forests and precious seas because that's what slightly more than half the population voted for?

The answer is a partial yes. That's democracy. That's how our society works.

We chose to elect a government that promises continuing economic mismanagement, increasing the divide between rich and poor, delaying technological advances, depriving Australians of modern transport, and ruining our rivers and seas.

The part that is not "yes" is that we don't have to see this election as the "final nail in the coffin" of Australia. It is tempting to fall into the despair trap and believe our fate is sealed forever. It is understandable but unproductive to lie down and accept that we chose to wreck our world and continue on a path of destruction - and that's the end of that.

Now is the time to get up, dust ourselves off, and continue to push for responsible government and responsible action.

Remember that about half the country did vote for a fairer, more compassionate country. Half of us want to repair our damaged rivers, look after our farmland and forests, protect our remaining wildlife, and do what we can to save the reef. Around one in two Australians know that we will sooner rather than later need to work with the rest of the world to deal with climate migration. We will need to continue to produce food, feed and fibre for more people despite the worsening weather. To survive if not thrive we will need to work as a cohesive society, not the divided nation that people like the execrable Peter Dutton want.

That means we must continue to do what we can, but do it better. We need to continue to push for businesses and industries to take the lead where our federal government won't. We need to support the efforts of state governments to expand renewable energy and get off the fossil fuel train. And we need to demand accountability and openness from our politicians. We need to make sure everyone can see the impact of making the rich richer, the poor poorer, and the land and water degraded.

We might not succeed. That doesn't mean we shouldn't try.

Australians yesterday chose a rocky road, maybe confusing it with the sweet. We could have chosen a slightly smoother (though still rough) path, but we didn't. Let's do what we can to show the world Australia can be better.

How about changing and clarifying IPCC targets for global mean temperature

Sou | 5:25 PM Go to the first of 29 comments. Add a comment
The aim is to limit global warming to 1.5 C above pre-industrial temperatures; however, there has long been some contention and confusion around what is meant by the targets of 1.5 C and 2 C.

I don't know that anyone will ever agree on what pre-industrial means exactly, which gives a lot of room for inept leaders to wriggle out of their obligations. That's why I'm suggesting the IPCC and its member countries set and agree on targets where the meaning is clear, tangible, more precise, and to which people can relate more readily.

My idea is to change the simple message of 1.5 C or 2 C above pre-industrial to 1 C or 1.5 C above the 1951-1980 mean.
