what did all that lead do to peoples’ IQ? it had to go *somewhere* in the body.
sciam.bsky.social Scientific American @sciam.bsky.social · 4d
A small study found that exposure to lead—a dangerous heavy metal—has fallen by a factor of more than 100 since the 1960s.

However, the researchers warn that all the gains in lead exposure could be reversed if pollution policies change. bit.ly/4ryhLH2

The lead concentration in hair samples before and after the establishment of the Environmental Protection Agency. It has steadily plummeted since the 1960s.

There are five times as many people alive today as there were in 1900. Yet humanity is better fed than at almost any point in its history.

@ilmatieteenlaitos.fi mitähän tuo Ilmanlaatu Nyt -sivusto oikein mittaa? Tampereelle antaa tänään kaikki pisteet vihreää vaikka just nyt ruuhka-aikaan liikkeellä ollessa ilmassa on pistävä pakokaasujen haju. Ainakin näillä seisovan liikenteen kohdilla kuten Areenan kansi.

Tuulettomuus toki selittää

Three facts:

- Methane has caused ~30% of the warming we have seen so far.

- Curbing methane emissions is also one of the fastest ways to bend the curve on future warming. It’s a “emergency brake”.

- And the food system emits over half of global methane emissions.

We can’t ignore the largest source of methane
Food is the largest source of human-caused methane – we ignore it at our peril

the problem with doomscrolling is that overwhelming feeling of powerlessness. I don’t want to resign to being a spectator, but what can one do..

our family spent almost 24 h without electricity (because of a winter storm). This will happen again and makes me think - if experiencing *this* won’t make you consider a V2L-capable vehicle (usually EVs) then I don’t know what will. #powercut #ev

”pakotteiden seurauksena kysyntä Persianlahden ja Lähi-idän maiden öljylle kasvaa.”

OK, hienoa ettei kukaan enää osta Venäjältä, mutta eikös tässä vain siirretä diilit roistovaltiosta toiseen?

Ehdotus.

Joka kerta kun metsäyhtiö vahingossa - eli piittaamattomuuttaan - tuhoaa jonkin arvokkaan luontokohteen, se etsii, ostaa ja suojelee korvaukseksi vastaavan kohteen.

Veikkaan, että nämä "vahingot" vähenisivät lähelle nollaa melko nopeasti.

Tampereen Museoiden yössä. Luokkatietoisuus elää vielä: Työväenmuseo Werstaan workshopissa arkarreltiin osuuskauppakasseja, Milavidassa aatelisrälssiin sopien rannekoruja.

Vuonna 2025 on nykykapitalismi tienhaarassa. Tuleeko joku oligarkkiluokka aatelisten tilalle?

I think a lot about what Carl Sagan said in one of his final interviews.
"WE'VE ARRANGED A society based on science and technology, in which nobody understands anything about science technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces. Who is running the science and technology in a democracy if the people don't know anything about it?" "Science is more than a body of knowledge, it's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious, who comes ambling along."

Fossil fuel companies caused $28 trillion in climate damage according to new study.

It’s Saudi Aramco, Gazprom, Chevron, ExxonMobil, BP, Shell, National Iranian Oil Co., Pemex, Coal India and the British Coal Corporation.

Yet, they claim to be „part of the solution“. 🤷🏽‍♀️

Voiko Suomessa olla fossiileja, kun kallioperä niin supervanhaa? tuo on voinut tulla myös jään tuomana Ruotsin puolelta.
