I opened the first IPCC report, released in 1990, and copied their scenario graph for CO2 emissions.

I marked the latest data with a red dot. Carbon dioxide emissions in 2023 were 40.7 GtCO2 (= 11.09 GtC).

Whatever you think about the IPCC you must admit their business-as-usual calculations were pretty robust.

Edit: previous version of this post also talked about methane, but here story is not as clear, see down below: https://mas.to/@jackofalltrades/111731258956894444

A Nigerian living in the UK has "discovered" a new lake and named it Iyi Ojemba.

Mazi Uba Acho, a native of Igbo Naton in W Africa, highlighted the absurdity of the colonialist mindset that sought to claim discovery of places already known to locals. He cited Mungo Park's claim to the River Niger in Nigeria and David Livingstone's claim to the Zambezi River, Zambia, and Victoria Falls, Zimbabwe.

Tell your kids about Ruby Bridges, the first black child at an all-white public elementary school in Louisiana.

She turned 68 last year.

She’s only 68.

68.

Exclusive: Documents raise questions about UCLA’s suspension of ecologist

A committee found that Priyanga Amarasekare broke rules after she alleged discrimination by colleagues. It recommended light sanctions — but the university chancellor issued stronger ones.

We’re feeling the love today while looking at this image of our Pale Blue Dot. 😍 Voyager 1 took this photo of Earth from about 3.7 billion miles (6 billion kilometers) away on #ValentinesDay in 1990.

Just a quick update - #Antarctic sea ice extent is still the lowest on record for the current date.

We will wait and see if it breaks the record set from just last year.

Password strength is a very confusing concept, which has shown very clearly in the discussion around the #LastPass breach and #Bitwarden flaws. I tried to make it as easy to understand as possible, not sure whether I succeeded.

TL;DR:
· Password managers are a single point of failure, so their master password has to be strong.
· What looks strong to you isn’t necessarily a strong password.
· Long passwords aren’t necessarily strong. Case in question: “choose a phrase from a song.”
· I suspect that almost all real-world passwords have less than 35 bits of entropy. Especially with zxcvbn considering 33 bits as “strong” and even password manager vendors not questioning that.
· AFAIK the only realistic way to get a strong password is generating it randomly.
· Diceware is a good way to generate passwords that are both secure and rememberable.
· “Regular” people don’t need more than four words (using a word list for five dice). Valuable targets need five words for better protection, someone who could become a target of a state-level actor should be safe with six words.
