Geoengineering Gets Closer to Fighting Climate Change
Using technology to soften the effects of climate change may soon become a reality.
Using technology to soften the effects of climate change may soon become a reality. Geological engineers who believe technology can be harnessed to help stop global warming are beginning to move their experiments out of the laboratory.
Seeding clouds with tiny salt particles, for example, would increase the number of water droplets the clouds could contain, helping to make them brighter. And brighter clouds would reflect more sunlight back into the atmosphere, allowing the Earth to cool slightly.
There are still technological obstacles to the idea. For the cloud seeding project, a sprayer is needed that can create particles "a ten-thousandth of a millimetre in diameter at a rate of 1,000 trillion a second." Technology, however, may not be the ultimate stumbling block of geoengineering projects.
"Cloud-brightening on the scale imagined requires less than a liter of seawater a second."
Whether humans intentionally tamper with the climate will depend on sufficient oversight programs to make sure the research is carried out in a regulated manner.
In his Big Think interview, Bill Chameides, dean of Duke's Nicholas School of the Environment, says plans for humans to control the global climate are premature. One danger is that if we successfully counteract warming, governments will have less incentive to limit carbon emissions:

The Oxfam report prompted Anand Giridharadas to tweet: "Don't be Pinkered into everything's-getting-better complacency."
- A new report by Oxfam argues that wealth inequality is causing poverty and misery around the world.
- In the last year, the world's billionaires saw their wealth increase by 12%, while the poorest 3.8 billion people on the planet lost 11% of their wealth.
- The report prompted Anand Giridharadas to tweet: "Don't be Pinkered into everything's-getting-better complacency." We explain what Steven Pinker's got to do with it.
Moans, groans, and gripes release stress hormones in the brain.
Could you give up complaining for a whole month? That's the crux of this interesting piece by Jessica Hullinger over at Fast Company. Hullinger explores the reasons why humans are so predisposed to griping and why, despite these predispositions, we should all try to complain less. As for no complaining for a month, that was the goal for people enrolled in the Complaint Restraint project.
Participants sought to go the entirety of February without so much as a moan, groan, or bellyache.
- Facebook and Google began as companies with supposedly noble purposes.
- Creating a more connected world and indexing the world's information: what could be better than that?
- But pressure to return value to shareholders came at the expense of their own users.
