I live in a mountainous region of south-central British Columbia, the central Kootenay. Jasper Park and township are over 700 kilometres from me. Despite the distance, I am able to imagine the shock and horror of fire destroying … well, everything. I feel, though, that this kind of disaster is just going to keep getting more frequent.

Recent NASA research suggests that warming trends in the Arctic during the past 40 years aren’t due to CO2 emission increases. Instead, the spike in Arctic temperatures during the past forty years appears to be due to reduced aerosol particulates, specifically to reduced sulfates in the atmosphere. The sulfate reduction is believed to be the result of improved emission standards that were implemented to, ironically, improve the environment through reductions in acid rain. Aerosol sulfates reflect heat back into space, reducing temperatures, whereas different aerosols, termed “black carbon aerosols” and produced largely by burning coal, have the opposite effect: holding heat in.
Liars, damned liars, and statistics. Apparently, several of the most “reliable” temperature recording surveys in the world indicate that the Earth’s average temperatures are actually showing a downward trend during the last decade. But the single most quoted source, NASA, says exactly the opposite. From an article on The Register…
