It started with a tip from the local #FirstNation of a “bump on the sea floor” where the fish liked to be & led to the #discovery of #Canada’s only known live #CoralReef.
Deep sea #ecologist Cherisse Du Preez worked with the #KitasooXaixais & #Heiltsuk First Nations & began searching for the #Lophelia coral #reef in 2021, taking a remote-controlled submersible deep into the ocean in #FinlaysonChannel, about 500 kms NW of Vancouver.
About a dozen years ago, I crocheted a coral reef costume for myself, inspired by the big international coral reef crochet project. Random secondhand yarns, lots of hyperbolic shapes. Can't see in these photos, but some of the shapes have tiny beads sewn inside. #crochet#costume#coralreef
"South-east #Australia#marine#heatwave forecast to be literally off the scale - Patch of Tasman sea expected to warm over spring and summer to temperatures that risk significant losses to sea life
Australia’s south-east could be in for a marine heatwave that is literally off the scale, raising the prospect of significant losses in fishing and aquaculture.
The Bureau of Meteorology has forecast a patch of the Tasman Sea off Tasmania and Victoria could be at least 2.5C above average from September to February, and it could get hotter.
Oceanographer Grant Smith said the colour-coded scale the bureau uses to map forecast sea surface temperature anomalies stops at 2.5C. “We didn’t account for anomalies that high when we developed this ... it could be 3C, it could be 3.5C, but we can’t see how high it goes,” he said.
...
South-eastern Australia is a known climate change hotspot with its waters warming about four times faster than the global average."
In der Klimawissenschaft ist ein Kipppunkt definiert als "eine kritische Schwelle, jenseits derer sich ein System neu organisiert, oft abrupt und/oder irreversibel" (Lenton et al., 2008). Hier sind 10 #Kipppunkte, die für uns zunehmend an Bedeutung gewonnen haben.
"Einige der im #IPCC-Bericht erörterten abrupten Klimaänderungen und Kipppunkte könnten schwerwiegende lokale Klimareaktionen nach sich ziehen, wie extreme Temperaturen, Dürren, Waldbrände, Verlust der Eisschilde und Zusammenbruch der thermohalinen Zirkulation.
Es gibt Hinweise auf abrupte Veränderungen in der Erdgeschichte, und einige dieser Ereignisse wurden als Kipppunkte interpretiert (Dakos et al., 2008). Einige davon sind mit bedeutenden Veränderungen des globalen Klimas verbunden, wie z. B. die Interglaziale im Quartär (vor 2,5 Millionen Jahren) und die rasche Erwärmung während des thermischen Maximums im Paläozän und Eozän (vor etwa 55,5 Millionen Jahren; Bowen et al., 2015; Hollis et al., 2019).
Solche Ereignisse veränderten das planetare Klima für zehn- bis hunderttausende von Jahren, aber mit einer Geschwindigkeit, die tatsächlich viel langsamer ist als der projizierte anthropogene Klimawandel in diesem Jahrhundert, selbst wenn es keine Kipppunkte gibt" (IPCC, 2021).
Climate change is an immediate threat to the majority of the world's population.
We need a local, regional, state, national, and international "moon shot" type of concentration of effort using available resources while developing and advancing new science and technologies to counteract the damage humans have caused.
Without this type of all-out, universal cooperation, human civilization, and perhaps humanity itself, are in imminent danger of extinction.
"No part of the planet is free of plastic waste, and coral reefs are no exception, but scientists have now made the discovery that the deeper the reef, the more plastic debris it is likely to have."
Petrofuture map of San Diego--vintage Shell gas station map with 66m of sea level rise. The highest level predicted by the IPCC if all the ice caps melt.
@ConspiracyOfCartographers well, 66m doesn't account for the hydrostatic rebalance of the continents like #Antarctica that will rise significantly due to lack of kilometers of ice.
