"Experiments to dim the sun could start"

Seen this pop up on a couple of news sites recently, and have to say this doesn't sound like a good idea, what could possibly go wrong?

They've been doing it in the north west for years. It's obvious as you crest saddleworth.

I had to check the date when I saw the thread title.

COUGH -chemtrails-

They have been doing this for years, look up geo engineering, plenty of patents around for distribution systems.

I've always laughed at talk of 'chemtrails'.

[simon_harris]

As CT's go it is certainly an interesting one, the science is certainly there as are the patents and as a concept it has been widely discussed for a long time.

Just get Elon to go and put a big sun brolly into space a few million lightyears away towards the sun........

[otolith]

Irony.

Hang on I thought global warming was caused by us all driving our cars and eating steak and had nothing to do with the Sun?

American Congresswoman Mary Miller recently said

'....God controls the climate because He controls the sun....'

So no need for mere humans to fk about with climate change, God has it covered.

Mmmmm

I thought they wanted to cover the country in solar panels to catch as much of the sun as possible ?

Now they want to turn the sun down ?

It's to do with an increased proportion of the solar radiation reaching the atmosphere being retained within it.

[cliffe_mafia]

The only way I could be more fuming about this is if I owned solar panels.

[Radec]

Who's heading this up, Mr Burns?

[IanH755]

As a country with some of the lowest "Hours of sunlight per annum" I can't help but feel if this experiment may not be worthwhile to carry out here, instead of maybe central Australia, or the Sahara etc.

He'd be overshooting it by quite a margin. The sun is only about 8 lightminutes away

so, re-creating a side effect of the industrial revolution that artificially kept the planet's temperatures down - AKA global Dimming.

https://en.wikipedia.org/wiki/Global_dimming

A realistic alternative theory that by cleaning up the atmosphere of large particles we are actually allowing teh planets temperature to revert to the correct temp point that it should be at, and that it has been kept artificially cold by a smog layer.

do wish they would make their minds up ....

Global Warming was canned when it couldn't be used to fit narratives anymore, thus the phrase Climate Change being thrust into the mainstream instead.

I should add that while I believe the climate has changed, and it is likely partly to do with Human interference, I don't believe we're on the edge of a global climate catastrophe that we're constantly sold.

Blaming humans is dogma, don't swallow it. Data on the other hand shows that it ^ hasn't happened as described/claimed in recent decades even with CO2 levels increasing to over 420ppmv. Causality matters. According to Kato and Rose (2024) absorbed shortwave (SW) solar irradiance has been increasing since 2000 at a rate of +0.7 W/m² per decade. This is nothing to do with CO2 and explains the measured top of atmosphere (TOA) energy imbalance which you refer to and it fully accounts for the surface imbalance estimate (0.6 W/m²).

Brucie Bonus...in addition to SW data above, Koutsoyianns and Vournas (2023) show no discernible impact on the greenhouse effect from 100 years of downwelling LW radiation data as CO2 levels increased from 300ppmv to over 400ppmv. "We conclude that the observed increase of the atmospheric CO2 concentration has not altered, in a discernible manner, the greenhouse effect"

Another interesting aspect of this news is that experiments increasing cloud albedo will have the desired effect on cloud albedo. However the planet's complex chaotic non-linear climate system is just that, involving couplings and feedbacks, so the overall output from any given input cannot be known with certainty as time goes by.

In God we trust; all others bring data

Nothing new under the....er...sun. The topic was already being explored in popular culture in the late sixties.



Hence, there was obviously some concern over the issue, but it was just that at the time everyone was far too stoned off their tits to do anything about it.
