The weather, currently.
One more warm day before a big change. Thursday will not be as bright, with variable cloudiness through breakfast time. There will be some sunny breaks and it will be mild, with a wake-up temperature near 11°C. It will be a great day for the kids, they can wear shorts to school tomorrow. Cloudy with sunny breaks through the afternoon with a high of 22°C (the seasonal norm is 16°C). The wind will be from the SW 20-40km/h and the UV index will be 4 or moderate. The evening will be pleasant for those who may want to enjoy a walk and see some of the Fall colours popping up in the neighborhood.
A sharp cold front moves in Thursday night. There will be cloudy skies, with some showers early in the night, and very cool air will move in behind it. The low will be 7°C. Friday will be a cold day.

More bad news about methane! A new study in Science covering the three largest oil and gas basins found that flaring — the method through which companies dispose of unwanted methane — is often significantly less effective than previously thought. For decades, the prevailing wisdom was that flaring destroyed methane with 98 percent efficiency, turning it into CO2 which (while still not exactly beneficial) does less harm to the atmosphere. Researchers found that unlit and inefficient flares are allowing roughly five times as much methane to escape than previously believed.
Methane has roughly 80 times the warming power of carbon dioxide and emissions have risen sharply since 2007, for reasons scientists don’t completely understand. Researchers worry that the rise in methane output may signal that we have entered into a self-perpetuating cycle in terms of climate change, making global heating even more difficult to reign in. Looked at in this light, the new study in Science on flaring inefficiency is both a depressing example of oil and gas laxity and a potential source of methane emission mitigation. Fix the flares and you can (slightly) bring down methane output.
