Why the right’s usual smears don’t work on Greta Thunberg

Greta Thunberg’s position is that (heavily paraphrased) the science of climate change has been settled for decades* and the time has come to deal with it. That the science really has been settled for decades is demonstrated in various ways including the simple fact that the core climate change science has not changed in decades and we really are running of time to get serious about the climate crisis (see the various IPCC reports).

“The Tiny Fish That Break a Fundamental Rule of Vertebrate Life”

The story of cryptobenthics – a category of fish that is literally the fast food of coral reefs. They fulfil this role by having roughly 70% of their population on a typical coral reef eaten every week. In a (very real?) sense, the only reason that these fish are not extinct is that they reproduce, hatch and grow quickly enough to replenish their numbers as fast as they are being eaten.

P.S. They “break” the fundamental rule that vertebrate spend most of their life as an adult. Cryptobenthics barely make it to adulthood before they are eaten.

“Just what is science anyway?”

This 1999 essay by Roger Bradbury is an intriguing answer to the question posed by its title.

Unfortunately, I have been unable to find a particularly clean version of the essay on the ‘net. What is available (as of 2019-05-21) is a readable if somewhat grainy PDF of the essay which can be found by Googling for

"just what is science anyway" "Bradbury"

If you get the same results that I got, the second hit will be a link to the PDF file for Roger’s essay.

Regardless of whether or not the above search works, Roger expanded on his answer in what became chapter 2 of the 2006 book Complex Science for a Complex World published by the Australian National University (ISBN 1 920942 38 6). That book is online at the URL below. While the entire book is likely to be an interesting read, Roger’s contribution is chapter two which is titled “Towards a New Ontology of Complexity Science”.

“Why this stunning dinosaur fossil discovery has scientists stomping mad”

A March 29, 2019 New Yorker article titled “The Day The Dinosaurs Died” describes the discoveries of a palaeontologist, Robert DePalma. In the article, DePalma claims to have found fossils from the first hour after the asteroid strike that ended the era of the dinosaurs (here’s the link to that article: https://www.newyorker.com/magazine/2019/04/08/the-day-the-dinosaurs-died).

DePalma’s first scientific paper describing his discoveries fails to describe many of the claims made in the New Yorker article. Needless to say, this has the palaeontology community more than a little riled up for at least a couple of reasons – that failing to describe some of the discoveries in scientific terms makes it very difficult for other palaeontologists to vet the claims, and announcing scientific discoveries in non-scientific media is just not done.

Here’s the link to a Macleans’s article describing the controversy: https://www.macleans.ca/society/science/why-this-stunning-dinosaur-fossil-discovery-has-scientists-stomping-mad/

“Beholding the Big Bang”

It will take the motor, coupled with the sets of reduction gears, 13.7 billion years (the estimated age of the universe) to complete one rotation of the last gear.

“Inside the quest to save the banana from extinction”

Banana plantations around the world are under attack for the second time in the past 100 years by the fungus Fusarium oxysporum cubense (Panama disease). The disease causes a banana tree’s leaves to wilt and curl which soon leads to the death of the tree.

This article tells the fascinating story of how the worldwide banana industry switched in the 1950s from the then ubiquitous but susceptible to Panama disease Gros Michel banana variety to the somewhat less flavourful and more delicate but immune Cavendish variety. Unfortunately, history is in the process of repeating itself as the Cavendish variety is now under increasing threat by a different strain of Panama disease . . .

“Researchers Made 3,900-Pound Boulders They Can Move by Hand, Giving More Insights Into Ancient Engineering”

By using concrete of different densities and some careful design, researchers were able to make quite large and quite heavy (up to 1,770kg or 3,900lb) monoliths which one or two adults could relatively easily move around and use to assemble larger structures.
