The Arctic Ocean, more and more acidic
It is known that much of the CO2 we emit is absorbed by the seas and oceans. Some of this absorbed carbon dioxide is transformed into carbonic acid, but thanks to other marine elements a high percentage of this acid is neutralized or, which is the same, does not influence the sea.
However, this is not the case in the Arctic Ocean. On the one hand, the amount of fresh water being melted by thawing, and on the other, in summer, this same thawing causes the size of the ocean to increase, leading to a higher absorption of carbon dioxide.
From 1960 to the present, the pH of Arctic waters has been reduced by 0.02 per decade, and although the consequences are not fully known, it is believed that some species are in danger of extinction, especially those of the outer skeleton, such as corals. Norwegian researcher Richard Bellerby considers that what is happening is irreversible.
Last week, during the blackout, seeing ourselves vulnerable, we began to investigate many people in order to understand what happened: how does the infrastructure that transports electricity work? Why is it getting old? I am fascinated by the physical phenomenon of electricity... [+]

Economists love the charts that represent the behaviors of the markets, which are curves. I was struck by the analogy of author Cory Doctorow in the article “The future of Amazon coders is the present of Amazon warehouse workers” on the Pluralistic website. He researches the... [+]
Wikipedian bilatu dut hitza, eta honela ulertu dut irakurritakoa: errealitatea arrazionalizatzeko metodologia da burokrazia, errealitatea ulergarriago egingo duten kontzeptuetara murrizteko bidean. Errealitatea bera ulertzeko eta kontrolatzeko helburua du, beraz.

Orain dela 20 bat urte, berrikuntzaren inguruan master bat egin nuen. Bertaraturiko gonbidatu batek esan zigun gizakion historian berrikuntza teknologikoaren eragile handiena gerra izan zela. Gerra, halaber, eragile handia da botere harremanen berrikuntzan.
