Fires set stage for irreversible forest losses in Australia – “Anybody would have said these forests don’t burn, that there’s not enough material, and they are wet. Well they did.”

By Matthew Brown and Christina Larson 18 January 2020 (AP) – Australia’s forests are burning at a rate unmatched in modern times and scientists say the landscape is being permanently altered as a warming climate brings profound changes to the island continent. Heat waves and drought have fueled bigger and more frequent fires in parts of […]

Empty nets and tropical fish in Tasmania as climate change hits Southern Ocean

By Royce Millar and Chris Vedelago 31 January 2020 (The Sydney Morning Herald) – Rising temperatures and climate change have been blamed for the failure of stocks of some of the most popular eating fish in Australia’s Southern Ocean to recover from declines despite more than a decade of protection. The troubling findings come as […]

Opioid deaths are surging again in Washington, D.C., reversing previous year’s decline – 2019 was second-deadliest year for drug users since the District’s opioid crisis began in 2015

By Peter Jamison 31 January 2020 (The Washington Post) – Fatal opioid overdoses are on the rise again in the nation’s capital, an alarming development for public health officials who had celebrated what previously appeared to be a downward trend in the city’s drug deaths. Preliminary data indicates that 220 people died of opioid overdoses […]

External carapace and pereopod exoskeleton of the Dungeness crab megalopae (a) in its undamaged form (b, c) and with dissolution presence ranging from mild (Stage 1; d) to severe (Stage 2; e, f) patterns showing similarity in the structural damages (g) or exposed crystals (h). Indicated is the scale of the measurements (μm). The undamaged megalopae originated from the offshore or northwards habitats characterized by low ∆Ωcal,60 vertical gradients, while the most severely affected megalopae came from the nearshore or coastal habitats with steep ∆Ωcal,60 conditions.

Dungeness crab larvae already showing effects of coastal acidification – “We found dissolution impacts to the crab larvae that were not expected to occur until much later in this century”

23 January 2020 (NOAA) – A new NOAA-funded study has documented for the first time that ocean acidification along the US Pacific Northwest coast is impacting the shells and sensory organs of some young Dungeness crab, a prized crustacean that supports the most valuable fishery on the West Coast. Analysis of samples collected during a […]

Australia bushfires contribute to big rise in global CO₂ levels in 2020

By Grahame Madge 24 January 2020 (Met Office) – A forecast of the atmospheric concentration of carbon-dioxide shows that 2020 will witness one of the largest annual rises in concentration since measurements began at Mauna Loa, in Hawaii, 1958. During the year the atmospheric concentration of CO₂ is expected to peak above 417 parts per […]

Scientists move Doomsday Clock closer to midnight – “We are now expressing how close the world is to catastrophe in seconds”

By Gayle Spinazze 23 January 2020 WASHINGTON, D.C. (Bulletin of the Atomic Scientists) – The iconic Doomsday Clock symbolizing the gravest perils facing humankind is now closer to midnight than at any point since its creation in 1947. To underscore the need for action, the time on the Doomsday Clock is now being expressed in […]

Winter rainfall in eastern Australia, 1900–2019. The unprecedented lack of winter rains in 2017, 2018, and 2019, and Australia’s hottest summer on record, contributed to the extreme drought that affected 100 percent of New South Wales and 67.4 percent of Queensland in 2019 and 2020.

Some say we’ve seen bushfires worse than this before. But they’re ignoring a few key facts.

By Joelle Gergis and Geoff Cary 13 January 2020 (The Conversation) – Every time a weather extreme occurs, some people quickly jump in to say we’ve been through it all before: that worse events have happened in the past, or it’s just part of natural climate variability. The recent bushfire crisis is a case in point. […]
