3 Scottish scientists walk into a bar...

One Proposal to Cool a Warming Planet: An Umbrella Made of Asteroids



Take that, space mirrors! Scottish scientists have a new way to shield us from the sun.

Average global temperatures will likely rise by 2 to 11.5 degrees by the end of the century, the UN's Intergovernmental Panel on Climate Change has declared. There is, of course, a very straightforward way to prevent this: reduce our carbon emissions. But for a host of reasons -- economic, cultural, political, and generally human -- implementing that solution is pretty much the opposite of straightforward. As the months and years march on, we're faced with the more and more likely proposition that we will be unable to change our ways until it's too late for the change to make a difference.





Ach noh

Hmm, wonder if they have any ideas on how to avoid the continued acidification of the oceans?

Loads and loads of Alka Selter into the oceans

As is mentioned in the article there are many scientists busy at work trying to find solution to climate change, I happened to catch a doc called 'Playing God with the Planet' that was about a group of them who want to mimic volcanic eruptions by seeding the higher atmosphere with sulfuric acid in order to shield the Earth from the sun rays much as the eruptions of large volcanoes have been known to do. Can't help thinking that it is one thing for Mother Nature to do so, but quite another for humankind to try and do the same.

:lol: Yeah, don't think Alka Seltzer makes enough to apply to the entire global ocean.

Norway limes rivers with 50,000 tonnes of calcite to combat acid rain, and that costs about $20 million a year. Works well for some salmon rivers during the critical periods like for smolt runs.

Pretty pricey if you apply that math to the globe, every year. 8O

And it would create even more acidification! These geoengineering solutions are fraught with unintended harmful consequences.

I was just funnin' ya.

Interesting practice in Norway.... Mind you, I would have thought that liming (sp?) the rivers would have a disastrous effect on wildlife though

I know, I laughed :lol:

It requires careful dosing. They need to have accurate measurements of the pH and river flows, or yes it could be disastrous, or ineffective.
