Carbon dioxide in varying concentrations has been around for millions of years. Plants, trees etc. depend on it, and here we are. But climate scientists know best – don’t they? Looks like another trip to cloud cuckoo land here, in pursuit of the absurd climate control illusion.

A new study lays out the theoretical plan of tethering a giant solar shield to a captured space rock, says Space.com.
Potentially, this contraption could protect Earth from the sun.
To help combat the effects of global warming, scientists are toying with an innovative idea to shield our planet from the sun with a spaceborne “umbrella” of sorts.
“In Hawaii, many use an umbrella to block the sunlight as they walk about during the day,” István Szapudi, an astronomer at the University of Hawaii Institute of Astronomy, said in a statement. “I was thinking, could we do the same for Earth and thereby mitigate the impending catastrophe of climate change?”
The reason carbon dioxide and other greenhouse gases contribute to global warming is that they trap sunlight around our planet that should be released back into space, ultimately leading to rising temperatures. [Talkshop comment – not much of an explanation there, just the usual assertions].
But it’s the sun, and not greenhouse gases, that creates the heat to begin with. That opens up the idea of building Earth a shade.
So, Szapudi drew up an “umbrella” of his own. It would rest at the L1 Lagrange point between the sun and Earth, hypothetically joining sun- or solar-wind-observing probes such as the Solar and Heliospheric Observatory (SOHO) and Advanced Composition Explorer (ACE) that dwell there today.
In theory, a large-enough solar shield could effectively block around 1.7 percent of solar radiation at L1, enough to prevent a catastrophic rise in Earth’s temperatures.

Teet-a-bo! …. Keek! ( In other words, more childish ideas ) Really beginning to wonder about the calibre … a point 22 will no longer do, … just too thick.
In all this heat, you see many folk using PLASTIC bottles for water. Lucky them! What did the Romans do when marching North? All those Servants must have had a serious problem bringing enough water & food to the front lines – when they didn’t know where the local Spring was .. Stop Oil then! – How’d you get an umbrella installed up there?

Are they quite mad? The vast majority of places, the vast majority of the time, have temperatures no different from those 25, 50 or 100 years ago. So the vast majority of places the vast majority of the time will be cooled below “normal”.
Once again climate nutters not understanding the data they base their Alarmism on.
The article admits it’s impossible…
However, any sort of solar shade is bound to face a stark engineering challenge: At L1, they’d be subject to both the sun’s and Earth’s gravities while experiencing a constant torrent of solar radiation. A viable shade would thus need to be massive — weighing millions of tons — and made of a material sturdy enough to stay in place and stay intact. Simply, we don’t have a practical way of launching that much stuff into orbit.
But to get around that issue, Szapudi proposed, much of the material itself can come from space — from a captured asteroid or even lunar dust. That matter could theoretically serve as a counterweight, tethered to a much smaller shield weighing only around 35,000 tons. Right now, even such a smaller shield would be far too heavy for a rocket to lift, but with advances in materials, Szapudi’s study suggests we could manage the feat in several decades. [bold added]

‘Advances in materials’ = hopium.
So they admit it’s the sun!!! Whatever happened to CO2? And that they think cooling the earth is beneficial is just out with the fairies. Not just ignored, but these people need keeping out of harms way, and an asylum seems the only option, they are that insane.
I assume the idiot that proposed this was running out of funding and came up with this lame brain idea to keep himself in his nice air conditioned office.
He should be thrown out of the university because of this stupidity.
“István Szapudi, an astronomer” who very likely has not conferred with the staff who put and maintain satellites at L1. Shades of the Dyson sphere, this, and just as dreamy. The only practical way to put that much tonnage in orbit is to use what is already zooming about there. But we can’t even put up a research base on the moon, much less invent the necessary space mining techniques. And that’s assuming in practice micro-controlling earth’s climate in that fashion doesn’t screw with the ecology.
I would be hugely embarrassed as an undergrad to proffer such a ridiculously impractical idea. This is stretching the process of a “study” to absurdity.
In theory, a large-enough solar shield could effectively block around 1.7 percent of solar radiation at L1, enough to prevent a catastrophic rise in Earth’s temperatures.
Along with CO2 reduction measures, it might be enough to put a dent in agricultural production and weaken natural growth generally. Marvellous 🙄
Complete misunderstanding of atmospheric CO2 leads to this lunacy.
A simpler, logical explanation is
