Writing on wildlife, technology, and nature
I swear, it is almost impossible to stop yourself. I promised I would be more disciplined, but I’m not. When someone who cares about climate change gets solar panels on their roof, the temptation to keep looking at how much energy you are generating is virtually irresistible. After a long and dark “La Nina” winter …

In a recent article for Grist, meteorologist Eric Holthaus claims that we are already locked into a devil’s bargain on climate change. The bargain asks us to weigh a trade-off between two things that pollution in the atmosphere does for us. On the one hand, it causes serious health and respiratory problems that kill over …

Ships large enough to carry cargo across the world's oceans have big engines. In fact, they have really big engines. The ones that power the monster container ships that are the linchpin of global trade stand over four stories high and stretch for most of the length of a basketball court. They weigh over two thousand …

An image in the online Encyclopaedia Britannica illustrating the various strategies for climate engineering has always bothered me. Alongside the highly technical and speculative proposal of placing orbiting mirrors in space to intercept the sun’s rays sits the highly unsophisticated and low-tech proposal of wrapping melting glaciers with huge sheets of white fabric. The juxtaposition …

Earlier this month, a major international conference on climate engineering* (also known as ‘geoengineering’) wrapped up in Berlin attracting headlines around the world. Next week, I’m travelling to a smaller academic meeting on the ethics and governance of climate engineering research. Next year, two outdoor tests of climate modification technologies are scheduled to begin. The …
Last week an article appeared in Forbes magazine bearing the title “As Humans Fumble Climate Challenge, Interest Grows in Geoengineering.” The article reports that during an appearance at Carnegie Mellon University, Dr. David Keith, one of North America’s foremost advocates for research into geoengineering, observed that in recent months serious discussion of geoengineering “really is …
