I just did a more rigorous computation for increasing Earth's albedo (reflectivity) using 92% efficient mirrors.
To get back to year 2000 albedo levels, we only need a band about 84 km wide (42 km North & South of the equator) of mirrors circling the earth.
The more you know!
There is a limit on how far we can let climate run away now, if we are to give the next generation an opportunity. See Runaway – mailchi.mp/caa/runaway-...

I'm not suggesting this is an open secret within the climate science community, but it's remarkable how little impact this sort of research is generating. Because if the rate of warming really has *doubled* then you can kiss goodbye to 2°C. www.carbonbrief.org/pace-of-glob...
"In case of a linear evolution, that corresponds to the mid‐point of the 20‐year period defined by IPCC as 1.5°C threshold. According to this, all data sets are near 1.5°C already and will cross that limit before 2030."

The worst possible news
This means 2C will likely be breached in the late 2030s
So much for us being on track for a 2.8C rise by 2100

"BREAKING: 3 of the 4 largest Gulf economies — Saudi Arabia, the UAE, and Kuwait — are reportedly discussing withdrawing from U.S. and other international investments as the economic toll from the escalating war with Iran grows, according to the Financial Times."

Tweet today from Ryan Grim of Drop Site. "An unarmed Iranian ship was invited, along with the U.S., to be part of an Indian Naval exercise, and its sailors paraded on land before the president. "The U.S. at the last minute pulled out of the exercise and instead attacked the Iranian ship with a torpedo. Breaking with all norms of civilization and warfare, we then refused to rescue the drowning survivors. The Sri Lanka Navy was left to pull the dead bodies from the water. "I am hard pressed to think of any other nation throughout history that would do something so cowardly and despicable. We are genuinely in a league of our own, and American media — mostly shrugging off the bombing of a girls school and acting as if carpet bombing Tehran is a normal military tactic — is deeply complicit."
Decent summary from Drop Site News. Misses the Australian 'contribution' (three of the submariners were Royal Australian Navy).
It's a feature of unlimited economic (capital) expansion.
To date, population hasn't been decoupled from global GDP, same as with energy and material throughput.
Capitalism demands a larger and larger pool of losers from whom fractional advantage can be squeezed.
"This civilisation is genocidal. Ecocidal. Omnicidal. Imperialist. Racist. Dehumanising. Degrading. Dystopian. Emotionally stunted. Culturally vapid. Spiritually impoverished. Intellectually enslaved. Why would any sane person want this to continue?"

El Niño and La Niña. The two extremes of Earth’s global weather cycle. For thousands of years, the oscillation followed a steady rhythm… until 2025.
This time, La Niña is breaking the rules.

"The US has asked Ukraine for help defending Gulf allies against Iranian drones, according to President Volodymyr Zelensky."
"He suggested, in particular, that Ukraine would be willing to swap its interceptor drones for more US Patriot air defences to protect against Russian ballistic missiles."
Iran claims to have hit a US oil tanker in the Persian Gulf and that the vessel was on fire.
There was no immediate confirmation of the incident or of a similar attack that Iran claimed earlier this week.

February CO2 data from Mauna Loa was just posted by NOAA, and the 3-year running average for the mean rate of atmospheric CO2 growth hit yet another new record high, now up to 8.15 ppm per 3 years.
And that dip in the early 1990's was Mt. Pinatubo.
An oil tanker anchored off Kuwait was struck by a large explosion on its port side, leading to an oil spill and environmental concerns.

CHINA HAS SUSPENDED DIESEL AND GASOLINE EXPORTS
China halts fuel exports to secure domestic supply amid Middle East disruptions.
Will likely result in higher fuel prices worldwide.
A clear sign of tightening energy tensions.
"Pentagon sought fresh supply of 13 critical minerals day before Iran attack"
"US is reliant on imports for most of the 13. China is a dominant global producer of all of them"
"Some have been subject to export restrictions by China
China has been using its market control as diplomatic leverage"
Long term closure of Strait of Hormuz would cause spikes in oil & gas prices, effect the production of fertilizers, semiconductors & electrical infrastructure as well as mineral extraction in Africa & high-tech manufacturing in Taiwan.

Roughly 44% of global sulphur, 31% of urea, 18% ammonia, 15% of phosphates & 20% of LNG are shipped through the Strait of Hormuz.
This will have immediate implications for fertiliser supply chains & farm input costs everywhere.
LNG is a key feedstock for ammonia & urea production via Haber-Bosch

I think you're right - this will probably incease the sales of EV's.
True about China & SE Asia, but closure will cause a global economic shock and oil deficit, raising prices for everyone. Then there's LNG. 1/3 of global fertilisers apparently go through Strait. Ships being diverted, so delays & $$. Saudi Arabia & UAE have pipelines, but capacity is only ~4–5 mb/d.
I've read the net effect of the 1973 oil embargo was ~7-14% of global oil consumption after increased production & 3rd party re-sales. Shortages made worse by government price control & allocation policies. 1973 unfolded over months. Total energy supply effected now includes LNG & was very sudden.
Yes:
Holy crap! Sea level rise is now ~6mm per year 👀
According to NASA's latest analysis (2024 data), global mean sea level is rising at about 5.9 mm per year, higher than the expected 4.3 mm/year due to ocean warming and ice melt. Rates have more than doubled since the 1990s

What you're looking at is not a sunrise — it's the Russian LNG tanker ARCTIC METAGAZ (IMO 9243148) struck by a massive explosion in the Mediterranean this morning. Photographed by crew aboard a merchant vessel, via Vanguard Tech.
Seems like the media should at least express some curiosity about this.
