    But I once saw a cyclist go through a red light …

    Why do people feel the need to tell me this? It’s not my job to defend cyclists who go through red lights just as it’s not my job to defend motorists who go through red lights. Or motorists who drink and drive. Or motorists who speed. Or motorists who go the wrong way down a […]

  • The age of science denial

    A commenter on the …andThenTheresPhysics blog has shared a terrific excerpt from a 100-year-old science book by Huxley and Gregory he found in his attic. It’s about the greenhouse effect and how we knew way back then that adding CO2 to the atmosphere would increase the surface temperature on earth. The atmosphere surrounding the earth […]

  • A new word: Reducetarian

    I just watched an interesting TedX talk about the negative connotations behind the words vegan and vegetarian. Tell a stranger you’re a vegan and they make all sorts of negative assumptions about you. This is why I prefer to call myself a plant-eater. A friend of mine once told me that when they first found […]

  • Gavin Schmidt: The emergent patterns of climate change

    This is a great TED talk given by Gavin Schmidt about how scientists use climate models to learn more about our climate (h/t Hot-Topic).

  • We are running out of time…

    A friend sent me a link to a good article this morning (thank you!) about climate change and how if we don’t address it soon, it may end up becoming impossible to address. It is based on a leaked IPCC report, working group III – policies to limit damage, which is due for release in […]

  • In praise of change

    I’m an impatient person. I also relish change. I’m not one of those people who fears it and who rejects everything new. Perhaps this is partly why I have no objections to implementing the changes needed to stem global warming and am perplexed why so many people fight against them. I read this great tweet […]

  • The higher you go, the hotter it gets below

    Physics was my favourite subject in high school. I still find it fascinating. This week I learnt something new about our Earth and its temperature and I want to share it, because explaining something to someone else, is often the best way of understanding it yourself. If we want to know what the temperature of […]

  • Factors besides CO2 – Myles Allen and Wally Broecker

    A great video (<3 minutes) from Myles and Wally about how other factors can modify the impact of rising greenhouse gases. Myles Allen is a Professor in the Atmospheric, Oceanic and Planetary Physics Department at the University of Oxford. Wally Broecker is a Professor in the Department of Earth and Environmental Sciences at Columbia University.
