“A picture emerges not of concern about wholesale fraud but of profound concerns that many scientists may be cutting corners and engage in sloppy science, possibly with a view to get more positive and more spectacular results that will be easier to publish in high-impact journals and will attract many citations.”

I will add the pressure is also to obtain ever more dwindling research dollars.

The COP 28 President is talking utter BS.
“Al Jaber is asking for a 1.5C roadmap – anyone who cares can find that in the International Energy Agency’s latest net zero emissions scenario, which says there cannot be any new fossil fuel development. The science is absolutely clear [and] that absolutely means a phase-out by mid-century, which will enhance the lives of all of humanity.”

American astronomer, mathematician and meteorologist Cleveland Abbe was born #OTD in 1838.

During his term as director of the Cincinnati Observatory in Cincinnati, Ohio, he developed a system of telegraphic weather reports, daily weather maps and weather forecasts, this being the area of his work and expertise for which he is probably best known. In 1870, Congress established the U.S. Weather Bureau and inaugurated the use of daily weather forecasts.

This is a con.

"Agriculture accounts for 91% of biogenic methane emissions.

A recent report by WWF found that the world’s five biggest meat and milk producers, including Fonterra, emit the same amount of greenhouse gases as major oil company ExxonMobil"

But count on people waving this around like an accomplishment; when they are really just showing how little respect they have for us.

Greta Thunberg (@gretathunberg) on the urgent need for system change...

Until recently, you could argue that it was possible to save the climate without having to change our behavior. But that is no longer possible. The scientific evidence is crystal clear: our leaders have left it too late for us to avoid major lifestyle and systemic changes. There simply are not enough resources left.

If we are to have a chance of minimizing further irreparable damage, we now have to choose: either we safeguard living conditions for all future generations, or we let a few very fortunate people maintain their constant, destructive search to maximize immediate profits. 

That's from page 240 in “The Climate Book.”

AI creativity has come a long way in recent years, but there's still something missing.

I really enjoyed this paper ( that explores what "creativity" really is, examples of artificial creativity in computers, and the gap between us and them.

The fun part is it was written in 1998. It's fascinating to compare LLMs to the examples Boden cites, to see how far we've come and how far we have left to go. The creativity framework she provides is super useful for doing this.

In particular, we still haven't made much progress in getting AI to understand what humans value, and how to use that to assess and refine its own work (hence iterative prompt engineering). There's also still a huge problem with depending on human curation. That's less obvious now that LLMs are just scooping up vast quantities of text instead of carefully curated datasets, but it's still happening behind the scenes (often with terrible worker conditions).

Our plastic nightmare...

Notably, over half of all plastic ever produced has been manufactured in the last two decades, and production continues to escalate. By 2040, plastic waste flowing into aquatic ecosystems is expected to triple, releasing an additional 1.5 trillion pounds of plastic into the environment.

And the problem gets worse when all this plastic starts breaking into smaller pieces.

Right now, you’re surrounded by high concentrations of microplastics. Look into the sunlight coming through your window, and you’ll see airborne microplastics floating around. Leave out a glass of water, and you’ll find microfibers from your clothes floating. Change your sheets, and you’ll see how many particles the fabric throws into the air. The dust in corners and lint on your clothes — it’s all plastic. And nearly everything around us generates microplastics, from synthetic fibers in carpets to polymer sealants on hardwood floors.

The threat posed by plastics has obvious and predictable repercussions for human health. Because they’ve invaded our bodies. Microplastics have now infiltrated our food chain, showing up in meat, table salt, and even in human breast milk. These minute particles, when ingested or inhaled, pose serious health risks, including inflammation, cardiovascular diseases, and neurodegenerative disorders.

The toxicity of plastics is further exacerbated by the chemicals they harbor, such as phthalates, lead, and brominated flame retardants. These compounds disrupt endocrine systems, causing reproductive disorders and developmental issues. Shockingly, even unborn fetuses are not immune, with plastic particles detected in the placentas of pregnant women.

We are caught in a plastic progress trap, where plastic has become essential for our living while propelling us into degradation, tainting every corner of Earth and our bodies.

The above excerpts are from a long and depressing piece covering not only health and pollution issues but also looking into attempted solutions.

Spoiler Alert: It doesn't appear that our nightmare will end anytime soon.



#Health #Science #Environment #Climate #ClimateChange #Pollution
