.This is from an article from NBC that was published in November of last year
.It’s about findings that were published Nov. 23 in the journal Environmental Research Letters by a pair of researchers from Harvard and Yale universities.
.project of atmospheric cooling ( solar engineering ) would not only be doable but also cheap at a Only cost only 3.5 billion
.Only cost 3.5 billion(Most of those funds would go into building planes able to carry big tanks of aerosol spray into the stratosphere, about double the cruising altitude of a Boeing 747.)
.Texas will have spent nearly a billion dollars replacing a single bridge in Corpus Christi. New York City subway-repair budgets routinely run into the tens of billions of dollars.
.That cooling wouldn’t reverse climate change. The greenhouse gases would still be there. And the earth will still be warming. Could cut the greenhouse contribution in half.
.What it does?
.Dump sulfur dioxide into the atmosphere, reflect light back into space. SO2 is cheap, and there’s lots of it
.We would need to get it up into the stratosphere. it stays aloft for a year or 18 months.
.The recent studies shows the approach really could cool down the planet. But it would not reverse climate change
.It wouldn’t be able to create more glaciers
.Alternative idea is to suck co2 out of atmosphere
.solar geoengineering has the potential to be one of the only options left.
.That’s worrying for a number of reasons,almost certainly be side effects that the sprayers couldn’t anticipate. as soon as it’s stopped its effects would go away within 18 months.
.No politicians, he said, would want to take the blame for a bad weather event that occurred the year after they voted to spray SO2.
.Hurricane Sandy happened on the year after we started putting this material up
Questions about it
.how sulfur would interact with other chemicals in the atmosphere?
.How would a big new batch of SO2 in the atmosphere affect the ozone layer?
. How would individual regions, agriculture or local water systems react to the sudden change in sunlight?
. How would the public react?
