Life on Earth does not enjoy change, and climate change is something it likes least of all. Every aspect of an organism’s life depends on climate, so if that variable changes, everything else changes too – the availability of food and water, the timing of migration or hibernation, even the ability of bodily systems to [...]

Cross-posted from NextGen Journal A few years ago, climate change mitigation became a major political issue. Before 2005, governments certainly knew that human-caused climate change was a serious problem – but the public knew next to nothing about it, so there was no incentive to act. However, between 2005 and 2007, a perfect storm of [...]

Cross-posted from NextGen Journal As an aspiring climate scientist, I have read dozens of books about climate change over the past few years. Here are my all-time favourites, which I present with Unofficial Climate Change Book Awards. (Unfortunately, the prizes consist entirely of bragging rights.) Best Analysis of Future Scenarios Climate Wars, by Gwynne Dyer View [...]

My second rebuttal for Skeptical Science. Thanks to all the folks who helped to review it! Further suggestions are welcome, as always. -Kate “What if global warming is just a natural cycle?” This argument is, perhaps, one of the most common raised by the average person, rather than someone who makes a career out of [...]

I hope everyone had a fun and relaxing Christmas. Here’s a book I’ve been meaning to review for a while. The worst part of the recent book by NASA climatologist James Hansen is, undoubtedly, the subtitle. The truth about the coming climate catastrophe and our last chance to save humanity – really? That doesn’t sound [...]
An Unlikely Priority

A small news splash surfaced this week over a recent paper in Nature, regarding the prospects for Arctic sea ice and, consequently, polar bear populations. Until this paper was published, studies had only examined business-as-usual scenarios. We didn’t really know whether or not, if we pursued aggressive mitigation, it would be too late to save the polar [...]
The Nature of Scientific Consensus

Cross-posted from NextGen Journal It is common for one to fail to grasp the difference between “consensus” and “unanimity”. A consensus does not require agreement from absolutely every member involved. Rather, it is a more general measure of extremely high agreement, high enough to accept and base decisions on. It’s stronger than a majority-rules style [...]

A year ago today, an unidentified hacker published a zipped folder in several locations online. In this folder were approximately one thousand emails and three thousand files which had been stolen from the backup server of the Climatic Research Unit in the UK, a top centre for global temperature analysis and climate change studies. As [...]
Geoengineering the Climate

Cross-posted from NextGen Journal Climate change would be a whole lot easier to fix if we could immediately see the results of our actions. First of all, we would have recognized the reality of the problem long ago, before very much harm was done. And even if we initially stalled on fixing the problem, we could [...]
