A school district in Houston has voted to redact chapters on vaccines and climate change, and parents and educators are worried

Nějak nebyl čas na to reagovat nicméně když už se to nakouslo, ale je něco jiného vodu (zjednodušeně) mít dostupnou pouze díky gravitaci, srážkám, nebo podzemní zásobě a nebo ji získávat skrze technologie, které jsou závislé na mikročipech a materiálech z druhé strany planety - a v jakém množství - neumím si představit odsolování pro zemědělské účely (ne že bychom také nemohli mnohem zeektivnit zemědělství jako takové) - a také, co potom s přebytečnou solí (která je mimochodem plná plastů :) )

Nemusí jít přímo o války, na to se dnes nehraje dělají se jiné naschvály, nebo sankce,.. Jižní Evropa o tom už dnes ví své.

The last 12 months (through April) have been the warmest on record by a large margin, at 1.65C (± 0.07) above preindustrial levels.

SHEFIK:
tak snad jim ta odsolena voda pomuze zalevat jejich farmy a chladit jejich reaktory na jihovychode zeme, to neni jen o pitne vode

April Heat Waves from Gaza to the Philippines Were Made Worse by Climate Change | Scientific American

Extreme heat has left hundreds of millions of people sweltering in record-breaking temperatures above 40 degrees Celsius (104 degrees Fahrenheit) over the past few weeks across a broad swath of Asia. From the Palestinian territories in the west to India, Thailand and the Philippines to the east, scorching conditions have caused at least dozens of deaths, ruined crops and forced thousands of school closures. Relentless heat waves have worsened the already precarious conditions for those living in refugee camps and in makeshift housing in dense urban areas. And the 1.2 degrees C of warming the world has already experienced has significantly cranked up such events’ severity, a new analysis shows.

Comments on Global Warming Acceleration, Sulfur Emissions, Observations

In this article, climate scientists James Hansen, Pushker Kharecha, and Makiko Sato discuss the acceleration of global warming. They note that global temperature continues to rise, reaching 1.56°C above pre-industrial levels as of April 2024. The authors attribute this acceleration to the decline in human-made aerosols, particularly from the shipping industry, which previously had a cooling effect on the Earth.

The reduction in aerosols, combined with the strong warming trend at middle latitudes and the switch from La Nina to El Nino conditions in the Pacific Ocean, has led to a significant temperature jump in 2023-24. The authors emphasize the importance of accurately evaluating the impact of human-made aerosols on the climate, as it has implications for understanding climate sensitivity.

They call for further research and modeling to better understand the complex interactions between aerosols, clouds, and the Earth's climate system. The authors also stress the need for continued monitoring of the Earth's radiation balance to improve our understanding of the factors driving global warming acceleration.

Ta jeho filmová řeč je prostě top! Jo a vychází jim z toho, že zemní plyn je horši (co se týče emisí sklenikovych plynu) než uhlí. Protože úniky.

Main cause? The relentless push to meet AI demand, which requires carbon-intensive steel, cement, chips.

Obecně nejsem velký fanoušek toho, jak pře-soustředění jsme na měřítko HDP oproti všemu ostatnímu, ale i v relaci k ekonomice se zdá, že ty zprávy nejsou zrovna pozitivní.

Trochu mi to připomnělo W. Nordhause a jeho publikaci, kde tvrdí, že globální prům. oteplení o +3C by znamenalo pouhý 2.1% pokles v globálním HDP, v případě +6C (!) pohých 8.5%,
poté co si on a další neoklasičtí ekonomové vymysleli "nobelovu cenu za ekonomii". Odůvodněním bylo, že většina zisku vzniká uvnitř budov, které lze klimatizovat :clown_face:

Climate change is affecting mental health literally everywhere (yaleclimateconnections.org)

“Farmers who can’t sleep, worrying they’ll lose everything amid increasing drought. Youth struggling with depression over a future that feels hopeless. Indigenous people grief-stricken over devastated ecosystems. For all these people and more, climate change is taking a clear toll on mental health…”

“For us, mental health isn’t just about individuals,” he said. “It’s about the collective well-being of our communities and the land itself. When nature suffers, so do we.”
