Apologies for my silence recently – I just finished writing some final exams that I missed for the AGU conference, so I’ve been studying hard ever since Boxing Day. I am working on a larger piece about climate models: an introduction to how they work and why they are useful. That will take about a [...]

What Happened At Durban?

Cross-posted from NextGen Journal Following the COP17 talks in Durban, South Africa – the latest attempt to create a global deal to cut carbon emissions and solve global warming – world leaders claimed they had “made history”, calling the conference “a great success” that had “all the elements we were looking for”. So what agreement [...]
A Little Bit of Hope

I went to a public lecture on climate change last night (because I just didn’t get enough of that last week at AGU, apparently), where four professors from different departments at my university spoke about their work. They were great speeches – it sort of reminded me of TED Talks – but I was actually [...]

Next week, I will be giving a speech on climate change to the green committee of a local United Church. They are particularly interested in science and solutions, so I wrote the following script, drawing heavily from my previous presentations. I would really appreciate feedback and suggestions for this presentation. Citations will be on the [...]
An Unmeasured Forcing

“It is remarkable and untenable that the second largest forcing that drives global climate change remains unmeasured,” writes Dr. James Hansen, the head of NASA’s climate change research team, and arguably the world’s top climatologist. The word “forcing” refers to a factor, such as changes in the Sun’s output or in atmospheric composition, that exerts [...]
The Rest of the World

Here in North America, we are surrounded with rhetoric denouncing the feasibility of climate change mitigation. It’s not possible to reduce our emissions, people say. It’s not worth it. The situation in the U.S. Congress regarding this issue is becoming so bizarre that hopes for an international agreement to reduce greenhouse gas emissions have grown [...]
Ozone Depletion and Climate Change
Posted in Science Lessons, tagged carbon dioxide, CFCs, climate change, copenhagen, education, environment, global warming, greenhouse effect, greenhouse gases, HFCs, kyoto, montreal protocol, ozone depletion, politics, risk management, science, sustainability on March 30, 2011 | 18 Comments »
“Global warming…doesn’t that have something to do with the ozone?” Well, no. Environmental issues are not all the same. It’s common for people to confuse climate change and ozone depletion, but they are separate issues – although they are indirectly connected in some interesting ways. Ozone, which is made of three oxygen atoms stuck together [...]
Technology as Communication

The relationship between technology and climate change is complex and multi-faceted. It was technology, in the form of fossil fuel combustion, that got us into this problem. Many uninformed politicians hold out hope that technology will miraculously save us in the future, so we can continue burning fossil fuels at our current rate. However, if [...]
Climate Scientists Out in the Cold

Cross-posted from NextGen Journal In the current economy, it’s not surprising that many countries are reducing funds for scientific research. It’s necessary to cut spending across the board these days. However, North American governments are singling out climate science as a victim – and not just reducing its funding, but, in many cases, eliminating it [...]
Extinction and Climate

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 [...]
