Major toilet paper brands are flushing our forests down the drain

The National Observer What runs through your mind when you’re deciding which toilet paper to buy? Sale price, roll size, pitiful single-ply or luxurious triple? Climate change might not make your list of considerations, but it should. Story here. Please also watch this video. "Truth in Advertising - a TV commercial as it should be"

Australian bushfires triggered prolific phytoplankton blooms vast distances away

Photo by Pierre Markuse The 2019–2020 Australian wildfires released more than twice as much CO2 as previously reported on the basis of different fire inventories, reports  a Nature paper.   An independent study  also published in Nature ,  suggests that aerosol emissions from these wildfires are likely to have fuelled vast plankton blooms thousands of kilometres away in the Southern Ocean.  The findings highlight the complex links between wildfires, ecosystems and the climate.  Climate-change-driven droughts and warming play a role in increasing the frequency and intensity of wildfires, which release CO2 into the atmosphere, potentially driving further climate change and increasing the risk of wildfires.  In the summer season of 2019–2020, around 74,000 km2 — an area roughly equivalent to 2.5 times the area of Belgium — burned in the eucalyptus forests in the coastal regions of Victoria and New South Wales, Australia. These wildfi

Deforestation and fires are shrinking Amazonian habitats

Degradation of the forest threatens the resilience of this ecosystem; around 21–40% of the forest cover is predicted to be lost by 2050, which will have large impacts on Amazonian biodiversity.  To better understand these impacts, Xiao Feng and colleagues investigate how forest fires have been affecting the geographic range of 11,514 plant species and 3,079 animal species over the past two decades.Up to 85% of species listed as threatened in the Amazon may have lost a substantial portion of their habitat owing to deforestation and fires in the past two decades, a study in Nature indicates. It is estimated that for every 10,000 km2 of forest that is burned, about 27–37 additional plant species and about 2 or 3 more vertebrate species that have more than 10% of their range in the Amazon will be affected. As fires move clos
