Bill & Melinda hope to dim the sun with stratospheric chalk dust
2021-03-24
[MAIL] The first test of a project backed to spray millions of tonnes of chalk into the stratosphere, in an attempt to 'dim the sun' and cool the Earth, could happen in June.

Harvard University experts will test the system by sending a large balloon 12 miles above the Swedish town of Kiruna and have it drop 2kg of chalk dust into the stratosphere.
4.4 lbs
The aim of the estimated $3 million mission, backed by billionaire Bill Gates, is to have the chalk deflect a portion of the sun's radiation, stop it from hitting the surface, and cool the planet.

The idea has been heavily criticised since its inception, with project director Frank Keutsch even calling the need for this scale of geo-engineering 'terrifying'.

And experts have warned that the unusual technique could be disastrous for weather systems in ways nobody can predict.

Backed by a range of private donors including Gates, the test mission is launching from Sweden as they could offer a launch by the end of this summer.

#24  Bravo!

#23  Bugs... off the pile...

If all of our unionized teachers
Would clap their erasers, and preachers
Eat vegan and wiccan
Instead of fried chicken
While children crunch eight-leggéd creatures...
Well, little will change,
Which, sez Science, is strange,
But to Bill these are wonderful features!

#20  I remember reading Clancy's Rainbow Six and thinking the environmentalist baddies intent on world destruction were an unlikely concept. Now Thanos is doing the same thing and nobody really mentions it.

#18  Balloon... check.
Chalk dust, 2 kg... check.
Swed..ohh ho ho Sweden, ha ha... check.
$3 million... check.

#17  I understand future updates to Windows95 will come with free aerosol chalk bombs. Enjoy yours for what it's worth.

#16  We have volcanoes California fires that can do that at no charge

#15  Isn't this air pollution? And why on earth is it legal?

#14  the 2kg figure appears in other accounts

the idea is to create a parcel of air about 1km by 100m at an altitude of about 12 mile and monitor the chemical reactions and other processes

I presume a control parcel will also be monitored

the scale of this experiment means it will have essentially no impact on world wide weather or climate and we might find out something

#12  I read a book once called 'Rings of Ice' as i recall the story was that scientists roped in an ice asteroid and broke it up in orbit around the earth with the goal of focusing more sunlight on the earth (this was during the 'Global Cooling' of the 70's - 80's).
Didn't work out well when the ice melted, fell to earth and triggered flooding. The people who were left ended up eating moss.

#11  until they can tell us what the temperature of the planet would be if humans never existed, they can keep their hands off the thermostat

#10  Or is mass starvation the goal?

Yes.

#8  Do they realize their precious plant based meat and diet is dependent on the amount of sunlight we have now? Or is mass starvation the goal?

#6  Wasn't this the plot for The Matrix?

In the movie, "Snowpiercer" an all-too-successful geo-engineering attempt to stop 'global warming' plunged the planet into a minor ice age. Oopsie!
