The Great Salt Lake is on the brink of collapse – “It’s terrifying”

By Carly Cassella 10 October 2022 (Science Alert) – Without urgent and major interventions, America’s Great Salt Lake could experience ecosystem collapse in the next few years. In a worst-case scenario, according to findings presented at the Geological Society of America’s 2022 Connects Conference in Colorado this past weekend, the world-famous body of salt-water has […]

Global map showing the highest marine heatwave (MHW) category experienced at each pixel in 2021 (reference period 1982–2011). Light grey indicates that no MHW occurred in a pixel over the entire year. (b) Stacked bar plot showing the percentage of the surface of the ocean experiencing an MHW on any given day of the year. (c) Stacked bar plot showing the cumulative percentage of the surface of the ocean that experienced an MHW over the year. Note: These values are based on when in the year a pixel first experienced its highest MHW category, so no pixel is counted twice. Horizontal lines in this figure show the final percentages for each category of MHW. (d) Stacked bar plot showing the cumulative number of MHW days averaged over the surface of the ocean. Note: This average is calculated by dividing the cumulative sum of MHW days per pixel weighted by the surface area of those pixels.

WMO: Four key climate change indicators broke records in 2021 – Past seven years have been the warmest seven years on record – “A dismal litany of humanity’s failure to tackle climate disruption”

GENEVA, 18 May 2022 (WMO) – Four key climate change indicators – greenhouse gas concentrations, sea level rise, ocean heat and ocean acidification – set new records in 2021. This is yet another clear sign that human activities are causing planetary scale changes on land, in the ocean, and in the atmosphere, with harmful and […]

WWF: Looming mass extinction could be biggest since the dinosaurs – “One million species could go extinct within the next decade, which would be the largest mass extinction event since the end of the dinosaur age”

29 December 2021 (DW) – Ever-growing environmental threats are pushing many animals and plants to the brink of extinction — the scale of which hasn’t been seen since dinosaurs died out, the German branch of the World Wildlife Fund (WWF) said on Wednesday. The stark warnings came as WWF Germany released its “Winners and Losers of 2021,” an annual […]

Ecosystems the size of Amazon rainforest “can collapse within decades”

By Jonathan Watts 10 March 2020 (The Guardian) – Even large ecosystems the size of the Amazon rainforest can collapse in a few decades, according to a study that shows bigger biomes break up relatively faster than small ones. The research reveals that once a tipping point has been passed, breakdowns do not occur gradually […]
