Hey all, I've been writing some articles for the good folks over at Singularity Hub, who'll help you keep on top of a lot of breaking technology news. Working with them has been great so far. You can see all my work here but there are also some highlights:

  What It Would Take to Suck CO2 Back Out of the Atmosphere

I briefly assess some of the various potentials for carbon dioxide removal (CDR) geoengineering. Lots of people ask me, when I talk about climate change, whether we can't just 'invent a machine that sucks carbon back out of the atmosphere'. The fact is, people are indeed working on this - although a better idea is to actually try to enhance natural processes, which are far better at removing and adding carbon to the atmosphere than we can hope to be. The issue is that any method to remove carbon dioxide from the atmosphere must be done on the same scale as we're currently putting it up there. And since that is currently on the scale of a vast, industrial activity, it's going to require a whole industry to suck it back out again. Best, as you always hear, to leave it in the ground in the first place.
