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 […]

Thousands of ships fitted with “cheat devices” to divert poisonous pollution into sea – “In the North Sea and some parts of the Channel, the water quality has already been heavily degraded”

By Wil Crisp 30 September 2019 (The Independent) – Global shipping companies have spent billions rigging vessels with “cheat devices” that circumvent new environmental legislation by dumping pollution into the sea instead of the air, The Independent can reveal. More than $12bn (£9.7bn) has been spent on the devices, known as open-loop scrubbers, which extract […]

Leaving microbes out of climate change conversation has major consequences, experts warn – “Climate change is literally starving ocean life”

By Ivy Shih 19 June 2019 (UNSW) – An international group of leading microbiologists have issued a warning, saying that not including microbes – the support system of the biosphere – in the climate change equation will have major negative flow-on effects. More than 30 microbiologists from 9 countries have issued a warning to humanity […]

Civilization destroying nature at rate “unprecedented in human history” – Up to 1 million species threatened with extinction, many within decades

Civilization destroying nature at rate “unprecedented in human history” – Up to 1 million species threatened with extinction, many within decades

6 May 2019 (IPBES) – Nature is declining globally at rates unprecedented in human history — and the rate of species extinctions is accelerating, with grave impacts on people around the world now likely, warns a landmark new report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the summary of which was […]

Canada warming at twice the global rate, government report finds – “Northern Canada has warmed and will continue to warm at more than double the global rate”

1 April 2019 (CBC News) – Canada is, on average, experiencing warming at twice the rate of the rest of the world, with Northern Canada heating up at almost three times the global average, according to a new government report. The study — Canada’s Changing Climate Report (CCCR) — was commissioned by Environment and Climate […]

25th anniversary edition of WMO’s State of the Climate report shows accelerating global warming impacts – “The data released in this report give cause for great concern”

28 March 2019 (WMO) – The physical signs and socio-economic impacts of climate change are accelerating as record greenhouse gas concentrations drive global temperatures toward increasingly dangerous levels, according to a new report from the World Meteorological Organization. The WMO Statement on the State of the Global Climate in 2018, its 25th anniversary edition, highlights […]

“Doomsday vault” town warming faster than any other on Earth – “The brutality of nature used to bring joy, but now it scares people”

By Sarah Lazarus 27 March 2019 (CNN) – In 2014, Mark Sabbatini noticed cracks in his apartment walls. Then a mysterious bulge appeared in his bedroom and the apartment block’s communal staircase became crooked. “Doors and windows weren’t shutting properly,” he says. Sabbatini, the editor of a local newspaper, was living in Longyearbyen, the world’s […]

Oceans absorbed 34 billion tons of carbon from fossil-fuel burning over 1994-2007 period, a four-fold increase over 1800-1994

14 March 2019 (NOAA) – The global ocean absorbed 34 billion metric tons of carbon from the burning of fossil fuels from 1994 to 2007 — a four-fold increase to 2.6 billion metric tons per year when compared to the period starting from the Industrial Revolution in 1800 to 1994. The new research published by […]

3-5°C temperature rise is now “locked-in” for the Arctic

Nairobi, 13 March 2019 (UN News) – Even if the world were to cut emissions in line with the Paris Agreement, winter temperatures in the Arctic would rise 3-5°C by 2050 and 5-9°C by 2080, devastating the region and unleashing sea level rises worldwide, finds a new report by UN Environment. Meanwhile, rapidly thawing permafrost […]
