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

@[email protected] As to methane, it's more complicated, and it seems I've made a mistake. IPCC 1992 Supplement (pages 10 and 30) says that annual emissions of CH4 amount to about 500 Mt, of which 60% is anthropogenic. That would give 300 Mt though, but their graph clearly has a value of about 370 Mt. Maybe they overestimated them in the 1990 report?

Nobody who is selling you a solution to a problem will ever teach you how to avoid having that problem in the first place.

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.

The total eclipse of 2024 is just over a year away. The path of totality passes over a number of major cities. These maps show a) the climatological cloudiness percentage, and b) the percent of time the sky is < 20% obscured by clouds. (April 1-15 between noon and 4 p.m. CDT). @AlaskaWx

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.
