Scientists: Maybe If We Only Dim the Sun a Little It Won’t Backfire Horribly

When it comes to geoengineering the planet to cool the climate, there’s rightfully a lot of hesitation. Blocking incoming sunlight might seem like a quick fix to rising temperatures, but doing so could quickly tie up humanity in a decades-long project with alarming side effects like shifting precipitation patterns and changes in hurricane season.

Planet-Hacking Became More Urgent and Terrifying Than Ever This Year

Somewhere between a viral fake story about Harvard researchers suggesting we ‘dim the sun’, and a major, government-funded report laying out how we might re-engineer the oceans to save coral reefs, it hit me last month: this whole geoengineering idea has become suddenly, frighteningly mainstream.

We’re Now Seriously Considering Geoengineering Coral Reefs to Save Them

Coral reefs are facing a crisis thanks to an ever-growing list of threats, from climate change to ocean acidification to pollution. In an effort to stem the rising tide of damage, the US National Academy of Sciences released a major report on Wednesday chronicling the high-tech interventions we might have to use to save coral.

No, Scientists Didn’t Just Suggest We ‘Dim the Sun’ to Stop Climate Change

Reports last week of a new paper from researchers at Yale and Harvard proposing “sun-dimming” to mitigate climate change sure sounded alarming. Trouble is, those reports misconstrued the cited research, which made no suggestion that we actually engage in so-called solar geoengineering. Read More >>

Y Combinator Is Funding Some Seriously Wild Ideas For Sucking Carbon Out of the Air 

It’s increasingly clear that we can’t maintain a stable climate without pulling carbon out of the air. But the technologies for doing so are are completely unproven at the scale needed. Which is why Y Combinator, a startup accelerator that’s invested in Airbnb, Stripe, Dropbox and other wildly successful companies, is now looking to fund carbon capture companies working on some pretty outlandish ideas.

Geoengineering Is Inevitable

Here’s what’s going to happen: Every year for the foreseeable future, scientists, activists, and citizens concerned about climate change will have a discussion in one form or another about geoengineering. There will be editorials and vague proposals in journals; there will be think pieces on the need not to do it, but to talk about it. These will increase in volume and urgency as our situation becomes ever clearer, perhaps starting right now, with the release of the latest and most dire Intergovernmental Panel on Climate Change (IPCC) report.

Yet Another Reason Geoengineering Won’t Save Us

Geoengineering our planet to solve climate change is one of the riskiest propositions humanity has ever considered. That’s largely because there’s no way to know all the consequences that come with reflecting sunlight back into space, particularly when it comes to the agricultural system that has allowed humanity to flourish for millennia.

The Surprising Reason Our Planet Isn’t Heating Up Even Faster

In research that adds new truth to the phrase “every cloud has a silver lining,” scientists are reporting that sulphate aerosol emissions have offset roughly a third of global warming over the Earth’s land, by scattering sunlight back into space. Read More >>

Geoengineering Efforts Against Climate Change Could Turn the Sky White

Regardless of whether or not geoengineering actually does anything positive about climate change, it'll probably have some unintended consequences. Take, for example, this theory that geoengineering will bleach the sky. Read More >>
