CO2 emissions for 2019 will hit record, but rate of increase is slower

Scientific American magazine reports that the Global Carbon Project has released a study that has bad news and just a bit of good news.

Global carbon emissions are expected to hit an all-time high in 2019, scientists say, smashing a previous record set in 2018.
…

There is some good news. The authors expect a substantial slowdown in worldwide fossil fuels emissions for this year. Emissions from coal, oil and natural gas expanded by about 2% globally in 2018. For all of 2019, they predict an expansion of just 0.6%.

Part of the slowdown can be attributed to declines in coal use in the U.S. and much of Europe, and lower-than-expected growth from other key coal consumers this year.

“We’re estimating a decline of 10% this year” for the U.S., said the Global Carbon Project’s executive director, Pep Canadell, “well above previous decline levels.”

But slowing the growth rate is not enough. We need to lower the rate altogether.

Philanthropy as a license to behave badly

I have had many posts about really awful wealthy people (the Sackler family and Jeffrey Epstein being noted examples) using philanthropy to cover over the stain of their actions and enable them to act like they are pillars of the community. The assumption is that these acts of generosity are after-the-fact attempts at covering up their ill-gotten gains or their evil acts and ingratiating themselves into society.

But Patricia Illingworth, a professor of ethics, writes that the problem is even worse and that the very act of philanthropy may actually give these people a sense that they have the right to behave badly, something she refers to as ‘moral licensing’.

I can’t believe I’m defending Donald Trump

I was intrigued by this news item.

One of President Donald Trump’s most common responses to intelligence briefings is to doubt what he’s being told, former Deputy Director of Intelligence Susan Gordon said Tuesday.

Gordon, an intelligence veteran of more than 30 years, said Monday that Trump had two typical responses to briefings.

“One, ‘I don’t think that’s true,'” Gordon told the Women’s Foreign Policy Group.

“The one is ‘I’m not sure I believe that,'” Gordon continued, “and the other is the second order and third order effects. ‘Why is that true? Why are we there? Why is this what you believe? Why do we do that?’ Those sorts of things.”

The article implied that Trump was asking these questions because he had got information from other sources that he liked and trusted more that went counter what the intelligence briefers were telling him.

In my own teaching of science, I had two goals: (1) to enable students to sufficiently understand (not necessarily believe) the scientific consensus on the topic we were learning so that they could use it to solve problems; and (2) to get in the habit of reflexively asking themselves the questions: What do I believe? Why do I believe it? What is the evidence for it? What is the counter-evidence against it?

I felt that these two things enabled them to function is the world of science as well as building up necessary critical thinking skills that would stand them in good stead in all areas of their lives.

So I cannot fault Trump for asking the intelligence officials such questions. Of course, it is not clear if he was actually seeking information in order to make better judgments or whether he was merely finding a way to reject conclusions he did not find congenial. Given what we know about him, the latter is likely but still the asking of such questions is a good thing.

Isn’t regular football brutal enough?

American football is a brutal game and so it should not be surprising that it occasionally erupts into outright violence. This feature was on display recently when Myles Garrett, a player for the Cleveland Browns, yanked off the helmet of an opposing player and repeatedly beat him on the head with it until he was restrained by other players. As is often the case there were events that led up to this assault but it was still egregious by any standards. In fact, yanking out a player’s helmet can be very dangerous because the neck is violently jerked. He has been suspended indefinitely but it made me wonder at what point this kind of on-field violence moves into a territory where the perpetrator is subject to legal prosecution.

Shattering Pyrex glassware

Pyrex glass dishes have a reputation for being able to withstand extreme temperatures from the very hot to the very cold. Hence I was surprised when someone I know did something that many of us have done without incident. He took a hot Pyrex baking dish from the oven and laid it on top of the rods that surround the burners you find on gas top stoves that keep the pots slightly above the gas outlets for the flame. But this time, the dish shattered into fragments, sending shards in every direction. He was lucky that he did not suffer any cuts from the high-speed bits of glass.

It turns out that this can happen on occasion and this video shows what can happen when a drop of cold water is placed in a hot Pyrex container.

The ‘uncanny valley’ and CGI

Computer generated graphics now enable some pretty amazing visual effects in films. In particular, it has been able to make animations look extremely lifelike. But interestingly, when it comes to depicting humans, there turns out to be a problematic element. As the animation gets more and more lifelike, audiences respond positively, getting more empathetic and engaged, but once it gets pretty close but is still not perfect, audience approval drops sharply and people tend to see the humans as creepy until the animation reaches close to 100% of being lifelike, as shown in this graph. The dip is known as the ‘uncanny valley’.

Saving the internet

The internet is under siege, its initial promise of providing free global access to everyone on a level playing field under attack from governments, big businesses, and secretive, anti-democratic forces. Tim Berners-Lee, one of the key creators of the World Wide Web, has been involved in a consortium that has come up with proposed measures to save the internet in a document titled Contract for the Web.

He discusses the plan in an interview.

The existential shock of death

James Baillie, a professor of philosophy, looks at why people struggle so much to accept the fact of death even though they know it is inevitable. He starts by looking at a passage from The Death of Ivan Ilyich (1886) by Leo Tolstoy.

The syllogism he had learned from Kiesewetter’s logic – ‘Caius is a man, men are mortal, therefore Caius is mortal’ – had always seemed to him correct as applied to Caius, but by no means to himself. That man Caius represented man in the abstract, and so the reasoning was perfectly sound; but he was not Caius, not an abstract man; he had always been a creature quite, quite distinct from all the others.

Baillie says this cognitive split described by Tolstoy arises because we see the world from both an ‘outside view’ and an ‘inside view’.
