The Fool Environmentalist
The following articles should be read with utmost care. Some of them are naughty in important senses, usually one can pick them out for their lame fearmongering character. The fact many authors are unaware or unconscious of their unseemingly blatter should not be much relevant. Sometimes specific knowledge repertoirs may be required to not fall victim of their tactics.
The Bad and the Ugly
Nasty papers and reality distortion.
- Bringing the chill of the cosmos to a warming planet
That is a little outrageous such misleading news built upon
a private company (SkyCool) and a patented technology from 2014.
The material, made of seven layers of silicon dioxide and hafnium oxide on top of a thin layer of silver, and is meant to be applied on top of already existing cooling systems, reducing system spending of electricity. Is not so cheap:
[the tester] would only owe SkyCool Systems the savings from his electricity bill for the first two yearsand
[it saved an experimental client] $3,000 over the course of the summer, but also requires addition of a coupled water pumping system. Where are they going to extract those minerals to make the films from? I dare say the generation process of this nanotech film consumes a lot of electricity, too, so I wonder how long before implementation of this system will actually start saving electricity.. There is something worse on top of it all, it seems there is much broken physics for merchandising. While system optimisations are welcome, the energy reflected from these super mirrors will be absorbed by atmosphere solid particles much before reaching stratosphere, so that is not going to help cool the planet, however they may think and be literal in
the world now cools off with the help of more than 3.5 billion refrigerators and air conditioners. See also (a) or (copy).
- Ice shelves propping up two major Antarctic glaciers are breaking up and it could have major consequences for sea level rise
The systems depicted in the paper are highly unstable and have
a high coefficient of roughness, and as such could only be
well represented stacking multiple snapshots of the system
within a time range. Anyway, much of the photos and videos
span Summer time periods in the Southern Hemisphere.
is actually published at end of Winter in
(end of Summer in
and much data was collected within the previous Antarctic Summer!
Accumulation of new ice upstreams will push older ice, that is
actually called Calving, you can see very sharp ice slobs.
Glacier shrinkage happens when ice melts from the borders upwards,
so you cannot really have calving at the same time as melting.

- Animal Populations Fell by 68% in 50 Years and It’s Getting Worse
One problem here is their sample size, animals can move
a lot and be hard to find, they may actually be hiding.
I will comment more on this later,
for now, see a video of similar subject (in English):

- 750 million genetically engineered mosquitoes approved for release in Florida Keys
about Oxitec and their chimeric mosquitoes
last year a lot. About 5% of the synthetic mosquitoes released
are males because Oxitec has not got a technique to remove
all males. Plus, their chimeric mosquitoes are a blend
of various exotic strains, so they are effectively spreading
new genetic mobile elements (transposons) to environments
where otherwise there was only endogenous strains.
Life finds a way.
- Microplastic particles now discoverable in human organs
- The title is misleading. The researches grew human tissue in petri discs and added microplastics. Then, they devloped a technique which can detect the plastic they added in the first place and are advertising that.
- Saco de lixo que inativa coronavírus é aprovado em teste da Unicamp
- Aqui é só uma notícia sensacionalista, o vírus só poderia ser inativado por contato com o plástico, sendo que é muito mais provável um vírus sofrer dessacação ou oxidação, pelo oxigênio ou luz forte do que pelo contato com o plástico.
- PCC officials admit mistake over melting Himalayan glaciers
- If only they all would apologise and get things correctly for the benefit of us all..
- Global Biodiversity Outlook 5, Plant Conservation Report 2020 and Local Biodiversity Outlooks 2 from the Convention on Biological Diversity.
- I will try and comment a litlte more later but these report goals seem much more a wishlist, how feasible are they in reality? There is a lot of beautiful words and images. I fear much is vague, unpractical.
- What’s causing climate change, in 10 charts
None of the charts plots Nature's carbon dioxide
emissions, which would make it difficult to actually see
human contribution to CO2, because it is
very small, comparatively. Nature emmits at a rate of
roughly 600-900 GTons of CO2/year, while humans
contribute with ~40 GTons/year..
See (a), (b). Also, you can look for natural carbon cycle in academic books; hopefully, where they can ackowledge proportions adequately. If you need more references, I can help.
Remarkable papers for their temperance or relevance. I may add some neutral papers here, too.
- It's the product not the polymer: Rethinking plastic pollution
article on that paper.
Much papers are written to say micro plastics are everywhere
but adverse effects other than their presence is not
well known. Far too many assumptions are made about plastic
danger and damage to the environment, specially plastic fibers,
without almost any factual support. Most plastic types are
chemically inert and should not present further problems other
than their physical property of dimension and scale.
At least the authors recognise that climate change may not have
to do with plastics in the following passage:
5. Capitalize on public interest and concern for the problems associated with plastic waste to raise the profile of greater, if less tangible, environmental concerns such as climate change and biodiversity lossin which they mean to using plastic controversy in favor of awareness of other more tangible and bigger problems. This is probably a neutral paper because I cannot agree with some of their statements about higher-level implications for the environment, but mostly this an effort of a step in the right direction for science.
- Fertility rate: 'Jaw-dropping' global crash in children being born
- Population stagnation is not good, what may be lurking after is decline. We can probably grow a large world population ever healthier if we can can lay hands on cheap energy. A sociologist friend of mine alerted me of this upcoming fenomenon: Europe is going to become black. Africans will be able to enjoy what richess was stolen from them. The comments section has about 2200 comments and still most want a shrikling population! Look at how badly some websites can interpret this same data. If we have got a larger population and give them the minimum necessary health, we may have thousands more very intelligent people who can deal with any nasty problem we face, how else will we produce more geniuses?
- Oscillations of the baseline of solar magnetic field and solar irradiance on a millennial timescale, Zharkova VV, 2019
- Mrs Zharkova is a solar physicist.
She has got
on youtube and I find very good.
That is a shame how her paper was retracted by the
Editors of Nature. I found their retraction note a lame excuse to try and
censor her paper!
Fortunately we have got links from
Mrs Zharkova has given alternative links to her paper
in the comments section of her retracted paper at Nature's website, too,
and she will publish the paper again soon.
Her paper is actually good, she describes the Sun Inertial Motion(SIM). As the sun orbits the mass centre of the solar system (barycenter) a little independently of Earth's and other planets barycenter orbits, the star and the planets come closer together and farther apart every amount of years. Currently, the sun comes closer to Earth at a rate of 0.00025 au per 100 years until 2700. This will warm the baseline Earth temperature in 0.5º C every 100 years, but other forcings will be stacked on top, in such a way the current grand solar minimum, which started in 2019, will last until 2055 and is going to be similar to the Maunder Minimum.
