Black carbon lofts wildfire smoke high into the stratosphere to form a persistent plume

Image
Science Magazine. In 2017, western Canadian wildfires injected smoke into the stratosphere that was detectable by satellites for more than 8 months. The smoke plume rose from 12 to 23 kilometers within 2 months owing to solar heating of black carbon, extending the lifetime and latitudinal spread. Comparisons of model simulations to the rate of observed lofting indicate that 2% of the smoke mass was black carbon. The observed smoke lifetime in the stratosphere was 40% shorter than calculated with a standard model that does not consider photochemical loss of organic carbon. Photochemistry is represented by using an empirical ozone-organics reaction probability that matches the observed smoke decay. The observed rapid plume rise, latitudinal spread, and photochemical reactions provide new insights into potential global climate impacts from nuclear war.   More here.

With warm weather, a high snowpack and floodwaters rising throughout the province, it may seem like B.C. is set to repeat last year’s weather patterns, which led to a catastrophic summer of fires. But it’s still too early to reliably predict…. More here.

Firestorm: How Wildfire Will Shape Our Future - a new book by Edward Struzik

Image
The Science Writers and Communicators of Canada is pleased to announce the winners of this year's book awards for books published in 2017.   The winner in the general audience category  is  Firestorm: How Wildfire Will Shape Our Future by Edward Struzik . A summary. For two months in the spring of 2016, the world watched as wildfire ravaged the Canadian town of Fort McMurray. Firefighters named the fire “the Beast.” It acted like a mythical animal, alive with destructive energy, and they hoped never to see anything like it again. Yet it’s not a stretch to imagine we will all soon live in a world in which fires like the Beast are commonplace. A glance at international headlines shows a remarkable increase in higher temperatures, stronger winds, and drier lands– a trifecta for igniting wildfires like we’ve rarely seen before. This change is particularly noticeable in the northern forests of the United States and Canada. These forests require fire to maintain healthy
