Arecibo Observatory:Views during the collapse & pre-collapse

w1ndex says...

This makes me sad. I hope a new one can be built but they were having trouble even getting the funds to repair it along with everything else going on there. I remember watching something on PBS about this in the '80s and it and NASA had me hooked on all things space-related. I almost chose astronomy as my major in college, sorta wouldn't mind going back for it, space still intrigues me.

You could selectively choose events, including NASA launches that were cancelled just as easily.

"Much deadlier than the current one" how exactly can you determine that when the current pandemic is far from over.

Having worked 5 years @ NASA (as a low-level worker), THIS is indeed common, and a skill we all learned.

Some serious abdications occur for this to be so endemic.

Interesting.
Why can't we use hydrogen balloons to put instruments at the right levels above earth, I wonder?
Do they think the static fluctuations, including the rifts, can be attributed to the almost total lack of atmosphere, or the lack of magnetic field on MARS, or something else?
Maybe I should read the NASA release.....nope, no answers there, only a near verbatim transcript of the narration.

Getting Cold (with thermal imaging)

Carefully

None of the endothermic reactions in this video have been suggested as methods to regulate global temperature, because even if they could be scaled up enough to make a global difference they don't address the systems which regulate the earth's temperature.

Some things which have affected global temperatures either up or down are:



Some people have proposed geoengineering to use those same mechanisms, for instance injecting sulphur dioxide into the stratosphere https://www.nature.com/articles/d41586-018-07533-4 or seeding the ocean with iron to fertilise algae https://phys.org/news/2016-03-seeding-iron-pacific-carbon-air.html although there are some concerns about both approaches.

So how do we use it to combat global warming?
