PANDEMIC: ‘Less awful.’ CDC, under fire, revises advice to drive alone
The health agency was criticized for telling commuters that single-occupancy cars were the safest form of transportation during the pandemic. It revised its guidance to include bikes and walking.
'Back Water' takes you on a canoe trip through a most unlikely wilderness area
The new documentary “Back Water” asks a lot of questions, but it mostly leaves the answers to the viewer. It’s those lingering questions that kept this quiet, even relaxing, viewing experience stuck in my mind for days afterwards. Clocking in…
US south-west in grip of historic ‘megadrought’, research finds
When Ken Pimlott began fighting US wildfires at the age of 17, they seemed to him to be a brutal but manageable natural phenomenon. “We had periodic [fire] sieges in the 80s, but there were breaks in between,” said Pimlott,…
How is global warming impacting the world’s tropical forests? – World Economic Forum
Trees remove carbon from the atmosphere when they are living, but release large quantities when they die. Scientists predict that just a 2˚C could push most tropical rainforests above their safe ‘heat threshold’ As they photosynthesise and grow, tropical forests…

I spent over 40 years in the Australian defence force. Our lack of preparedness concerns me | Chris Barrie
The past 18 years has been a period of significant disengagement and disinterest by the community in Australian political affairs. The political shenanigans described in Malcolm Turnbull’s recent book A Bigger Picture ought to be a wake-up call that as…
Low-severity fires enhance long-term carbon retention of peatlands
High-intensity fires can destroy marshy peatlands and cause them to emit huge amounts of their stored carbon into the atmosphere as greenhouse gases, but a new study finds low-severity fires spark the opposite outcome. By creating a decay-inhibiting crust on clumps of moist soil particles within the peatland, the smaller surface fires help protect the stored carbon and enhance peatlands’ long-term storage of it, even during times of extreme drought.
Tropical forests can handle the heat, up to a point
Tropical forests face an uncertain future under climate change, but new research suggests they can continue to store large amounts of carbon in a warmer world, if countries limit greenhouse gas emissions.
