Unprecedented die-offs, melting ice: Climate change is wreaking havoc in the Arctic and beyond #me6
phys.org/news/2021-12-u…
"In last 5yrs scientists have observed animal die-offs of unprecedented size, scope & duration in waters of the Beaufort, Chukchi & northern Bering seas, while recording the displacement & disappearance of entire species of fish & ocean-dwelling invertebrates"
This ecosystem is critical for resident seals, walruses & bears, as well as migratory gray whales, birds, sea lions and numerous other animals.

Not only are algae & zooplankton affected, but apex predators such as killer whales are moving into areas once locked away by ice—
..gaining unfettered access to a spoil of riches.

Scientists describe what's going on as less an ecosystem collapse than a brutal "regime shift"—an event in which many species may disappear, but others will replace them.
"It's like the gates of hell have been opened,"

..findings suggest that this vast, near-polar ecosystem—stable for thousands for years and resilient to brief but dramatic swings in temperature—is undergoing an irreversible transition.

Why nuclear power will never supply the world's energy needs

Analysis has concluded that nuclear power cannot be globally scaled to supply the world’s energy needs for numerous reasons.
phys.org/news/2011-05-n…
The results suggest that we’re likely better off investing in other energy solutions that are truly scalable
to supply 15 TW with nuclear only, we would need about 15,000 nuclear reactors. In his analysis, Abbott explores the consequences of building, operating, and decommissioning 15,000 reactors on the Earth,

Cost of #Nuclear 😳👇
In 2016, Japan's Ministry of Economy, Trade and Industry estimated the total cost of dealing with the Fukushima disaster at ¥21.5 trillion (US$187 billion), almost twice the previous estimate of ¥11 trillion (US$96 billion)

#CostOfNuclear 😳
Initial emergency response, together with later decontamination of environment, involved more than 500,000 personnel and cost an estimated 18 billion Soviet rubles—roughly US$68 billion in 2019 adjusted for inflation

Chernobyl disaster

Cleanup started in August 1979, and officially ended in December 1993, with a total cleanup cost of about $1 billion.[18]

Severe #nuclear reactor accidents likely every 10 to 20 years, European study suggests

👉Catastrophic nuclear accidents such as core #meltdowns in #Chernobyl & #Fukushima are MORE LIKELY to happen than previously assumed..
sciencedaily.com/releases/2012/…
Based on operating hours of ALL civil #nuclear reactors & # of #meltdowns that have occurred, scientists have calculated events may occur once every 10 to 20 years (👉based on the CURRENT NUMBER of reactors) -- some 200x 👀 MORE often than estimated in the past😳

Climate Crisis: Science failed to predict flood & heat intensity

Top climate scientists have admitted they failed to predict intensity of German #floods & the North American heat dome #cdnpoli #cdnmedia #bcpoli #bcheatwave

#climatescience former Met Office chief scientist Prof
told BBC News: "We should be alarmed because the IPCC #climatemodels are just not good enough

It’s is IMPOSSIBLE to say how much of an (existential) emergency we are in because we don’t have the tools to answer question🤔
Some scientists argue that it's futile to wait for the @IPCC_CH to say how bad the #climatecrisis will be 👀
