A 310 dB blast instantly deafening everybody within a 10 mile radius. Heard in Perth 1900 miles away.
That would grant humanity, mammals a few extra years of solid sea ice regrowth.
Several degrees av. temp. drop, worldwide.
While a super-eruption might delay things a few years all the CO2 already in the atmosphere would still be there when the dust cleared 5-7 years after the eruption. A minor blip on the scheme of things.
Yes indeed Tanada, alike a life extending treatment for a cancer patient facing the unknown.
Our dirty shield of aerosols should have been damaged by the corona crunch of human activity, might be some data on it.
Maybe the cause of the insane spike of temperatures last summer of Northern Asia.
You would expect a worldwide spike in average temp. as more solar energy reaches the surface.
https://www.reuters.com/article/us-clim ... SKBN21Z1RA(Reuters) - To contain the coronavirus pandemic, billions of people have been told to stay at home. In China, authorities placed almost half a billion people under lockdown, the equivalent of nearly 7% of the world’s population. Many other countries have since taken similar measures, initially in hard-hit Italy and Spain, and more recently in the United States and India.
The restrictions have sent financial markets into free fall. But they have also given residents in some of the world’s most polluted cities something they have not experienced in years: clean air.
https://arctic-news.blogspot.com/In other words, all polluting emissions need to be reduced. Moreover, a recent paper by Jorgen Randers et al. points out that, even if all greenhouse gas emissions by people would stop immediately, and even if CO₂ levels in the atmosphere would revert back to pre-industrial levels, and even if with relatively modest rises in methane levels, overall temperatures would still keep rising for centuries to come. Another recent paper, by Tapio Schneider et al., points out that solar geoengineering may not prevent strong warming from direct effects of CO2 on stratocumulus cloud cover.
Arctic blog always looks a bit grim.....I should get back on topic asap.
Just look at that above freezing at the peninsula, Northshore Siberia on Earthnullschool:
https://earth.nullschool.net/#current/w ... 949,73.015Plus 1 degrees C. at 73 NL, 84 E.
No deep purple on the arctic ocean but a stretch close to Greenland/Ellsmere Island.
Bit of air moving from the Atlantic to Pacific ocean, transpolar surface drift.
We can expect more of that in the near future.
