How we can curb the devastating effects of climate change is still hotly debated among politicians and scientists alike.
- Climate change and global warming are among the greatest challenges mankind has faced up until now.
- Researchers at Harvard have put forward a new solution — they want to reflect some of the sun’s heat back out to space.
- The process is referred to as “solar geoengineering” or “solar geotechnics”.
Climate change is one of the greatest challenges mankind has faced up until now.
How we’ll be able to curtail global warming and its devastating consequences is still very much a hot potato among politicians and scientists alike — and so far, the outcome of all these debates hasn’t been particularly fruitful.
However, researchers at Harvard may have come up with a solution that sounds just a little too good to be true.
In conjunction with researchers from MIT and Princeton, the group has suggested slowing down global warming by diminishing the amount of sunlight that reaches Earth’s surface.
Yes, you read that right. The technology is called solar geoengineering or solar geotechnics.
According to a study published in Nature Climate Change, the researchers are considering what might happen if they were to introduce sunlight-reflecting particles into Earth’s atmosphere.
The most important thing to note is that the researchers aren’t suggesting the method is a solution to rising global warming trends; it isn’t designed to bring temperatures back to pre-industrial levels nor does it address the real crux of the problem — the amount of carbon dioxide we’re producing.
In fact, too high a dose of “dimming” could even worsen the situation.
Postdoctoral research fellow at the Harvard John A. Paulson School of Engineering and Applied Sciences, Peter Irvine, was the lead author of the study.
“The analogy is not perfect,” he explained, “but solar geoengineering is a little like a drug which treats high blood pressure. An overdose would be harmful, but a well-chosen dose could reduce your risks. Of course, it’s better to not have high blood pressure in the first place but once you have it, along with making healthier lifestyle choices, it’s worth considering treatments that could lower your risks.”
The study suggests that this technology could the rate at which temperatures are increasing in half, which could offer global benefits without exacerbating problems in other parts of the world.
Alongside this measure, however, carbon dioxide emissions would still need to be reduced across the globe.
More water and fewer hurricanes
In order to better understand which regions might end up worse off if this geoengineering technology were combined with emission reductions, the researchers used a state-of-the-art, high-resolution model to simulate extreme rainfall and tropical hurricanes.
This is the first time a model of this sort has been used to look into the possible effects of solar geotechnics.
The researchers studied temperature and precipitation extremes, water availability, and also measured the intensity of tropical storms.
They found that halving global warming via geoengineering would not only cool the planet but also moderate changes in water availability and extreme precipitation in many places.
While the science surrounding geoengineering technology is over half a century old, it’s only recently — since our attention has been drawn Earth’s climate change — that scientists have intensified their researched the field.
Researchers at Harvard University have stressed, however, that our main response to climate change should be to curb carbon dioxide emissions; geoengineering alone simply wouldn’t be capable of fully remedying the root of the environmental problems.Eco Liberty Conclusion: Geoengineering has been going on for decades. Now Harvard Scientist want to spray Sulfur into the sky in attempt to stop global warming. In fact the solar activity has been in decline since the 1980s in solar cycle 21. Now sun is coming the end of solar cycle 24 and soon enter into solar sun 25. Harvard been to geoengineer the sky spray Inject Calcium Carbonate or Sulfur (S) into the earth atmosphere in an attempt to stop man made global warming. For I have no idea what Calcium Carbonate can do the atmosphere or the soil but I know what happen when Sulfur dioxide get into the atmosphere it block out the sun. We all know that plants need sunlight to grow; having planes that inject sulfur dioxide into the stratosphere to block out the sun to cool the planet even negativity affects the agriculture around the planet. Eco Liberty to Harvard University “I say no go to your geoengineering program”. Thing is that happen when big massive volcano erupted while the Harvard University geoengineering program when live?

That Why Harvard’s Geoengineering Program is a no go having aluminium (Al), barium (Ba) and strontium (Sr) is already bad enough and still don’t any idea what will do the atmosphere, the water and the soil but I do know what aluminium (Al) does the human body and there a link to wikipedia see what effect aluminium has on the human body also on animals and the environment https://en.wikipedia.org/wiki/Aluminium#Toxicity
All Geoengineering progarm should stop now and let nature take it’s cause. If you want the read about the Harvard University Geoengineering program heres the link below.
