The role we humans play in the continuing decline of Earth's biosphere knows no boundaries. Sadly - an essential part of human life - food production - remains part of the problem.

NASA   A thick blanket of smoke again darkens skies over northern India. Every year, farmers light large numbers of small fires between September and December—after the monsoon season—to burn off rice stalks and straw leftover after harvest, a practice known as stubble or paddy burning. Details here. By Larry Powell Smoke from burning stubble hovers over a small town in southwestern Manitoba, CA. Nov. 2020. A PinP photo. Canada is no stranger to the same practise. While "stubble-burning" in this country did not approach that of India's (at least not this year), numerous such fires were still common again this fall over the eastern prairies (See above) and in past years (below). Stubble-burning in Manitoba - circa 2005. Photos by PinP. Wildfire smoke (see brown) over the Canadian prairies last year. A NASA photo. Smoke from several large wildfires in Canada (now proven to be more severe, frequent and prolonged thanks to manmade climate change) was so thick and widespread

The Arctic is burning like never before — and that’s bad news for climate change

Alberta Premier Jason Kenney tours Fort MacMurray, site of major spring flooding - fails to see his own handiwork amid the damage. (Opinion)

by Larry Powell Fort MacMurray, AB. Photo credit - MacMurray Aviation.  Kenney was out inspecting the town of Fort MacMurray and region this morning, where major flooding has resulted in a mandatory evacuation order going out for the entire downtown area. Big trucks and low-lying buildings are reportedly submerged.  This is the same Premier who "dissed" a reporter recently for daring to ask if this might be the time to transition away from fossil fuels to renewable, sustainable energy. Kenney was especially shocked that he was a member of the Calgary press core, who are apparently all supposed to be cozy little members of the same club, parroting Kenny's anti-science lies about the consequences of continuing to exploit the tar sands.  This is also the same Premier who is spending millions of tax dollars from his own citizens, including desperate, unemployed oil workers, to fund a "war room," spreading mis-information about the consequences of a chan

Bushfires damaged Australian rainforest that is home to Earth's only living specimens of ancient species

PHYS ORG Rainforest foliage in Nightcap National Park, NSW Wales, an international heritage site hit hard by the bushfires. Photo by Naught101 Recent wildfires in Australia torched more than 48,000 square miles of land (for context, more than 40 Riding Mountain National Parks). The fires impacted ecologically sensitive regions, including an area called the Gondwana Rainforests of Australia World Heritage Site. This region contains a vast concentration of living plants with fossil records from tens of millions of years ago, according to Peter Wilf. Story here.

Australian blazes will ‘reframe our understanding of bushfire’

Science Magazine Fire on Cape Barren Is. Australia, 2016. Photo by Planet Labs, Inc. Summary Australia is on fire like never before—and this year's "bushfire" season, which typically peaks in January or February, has barely begun. Driven in part by a severe drought, fires have burned 1.65 million hectares in the state of New South Wales, more than the state's total in the previous 3 years combined. Six people have died and more than 500 homes have been destroyed. As  Science  went to press, some 70 uncontrolled fires were burning in adjacent Queensland, and South Australia was bracing for potentially "catastrophic" burns. David Bowman, a fire geographer and director of the Fire Centre Research Hub at the University of Tasmania in Hobart, spoke with  Science  about the unprecedented crisis. The flames have charred even wet ecosystems once thought safe, he says. And the fires have become "white-hot politically," with Prime Minister Sco

Fueling Concerns of Approaching Catastrophic 'Tipping Point,' Deforestation of Brazilian Amazon Hit Highest Level in Decade

Parched peatlands fuel Indonesia's blazes

Science   Fires set illegally to clear forests and peatlands for agricultural use in Indonesia are once again generating an acrid haze that has spread across that country and its neighbors. But a number of scientists say the haze emergency—which sent scores to hospitals with respiratory problems and led to school closures and flight cancellations—could have been worse. In the years since the last major haze event in 2015, Indonesia has moved to restore peatlands, making them more fire-resistant; enhanced restrictions on converting primary forests to agricultural lands; and stepped up enforcement of bans on fires. Experts praise the progress but say even more needs to be done, particularly in area of enforcement of laws holding plantation operators liable for fires on their lands even if they don't deliberately start them.

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

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.
