Default [CC] Global Sea Ice at record low

Nearly back to on-this-day record breaking, for 18 April

and going by Charctic just 37,000 sq km short

Many years ago I heard it mentioned that there was a forty year time
lapse in harvesting the results of the warming caused by Greenhouse
gas emissions. What we pumped our around 1980 therefore is now being
registered.

Looking at the temperatures and CO2 concentrations from 1930 on, I can
see a possible ten to twenty-year lag. After the Great Depression got
into its stride, CO2 concentrations flat-lined until WWII was well
underway. However, during this decade, temperatures started rising at a
rate as rapid as what we're seeing now. I suspect that, as industry
wound down, the atmosphere became cleaner, allowing more solar energy to
get through. The temperature curve didn't dip until during the war,
after industry started up again and the skies darkened.The fall
continued to about 1950, about when CO2 concentrations were starting to
increase. Temperature didn't start to rise until about 1970, when the
current steep rise began.

For global sea level rise it took about 12 years for the effect of the
Mt Pinatubo eruption to drop out of the global situation, and return to
the previous "normal".

apparently shows a return to record minimum global sea-ice for any 19
April, but Charctic still shows 75,000 sq km short.

Again charctic shows short by 16,000 sq km but that "byyear" graphic
looks definitely in record territory for 20 April of any year of the
satellite era.

Back into Charctic record minimum global sea-ice extent for any 21 April
of the satellite era, by 83,000 sq km below the 2017 previous such minimum.

Default [CC] Global Sea Ice at record low

The global sea-ice deficit for any 22 April, increased to 141,000 sq km
yesterday
https://sites.google.com/site/arctischepinguin/home/sea-ice-extent-area/grf/nsidc_global_extent_byyear_b.png
when, or even will, the global value reach 20 million sq km

A couple of pixel-counting SST spot values for the "El Nino" sea area of
https://origin.cpc.ncep.noaa.gov/products/analysis_monitoring/ensostuff/ONI_v5.php
for 01 Apr 2019 +0.93 and 22 April +0.93, so the next running mean
update will be up from 0.8 presumably, ie still increasing El Nino, the
world-wide influencer in the absence of a major volcano to counter its
action. What with all the "wrong kind of sea-ice" , ie lack of the
stronger MYI. I wonder if Greta Thunberg knows this bell-wether.

Still record breaking, now wrt 2018 and next month or so , for the
previous record minima, 189,000 sq km deficit for any 26 Apr.

Still not wanting to go over 20 million sq km, 1/3 million deficit at
336,000 sq km (Charctic)for any 27 April.

For any 28 April , deficit of 346,000 sq km.
I'd forgot to say that this lack of sea-ice situation, for the last week
or so , has applied to both Arctic and Antarctic individually and
combined, ie affecting both "ends" of the planet at the same time.

For any 29 April, deficit 276,000 sq km and 91,000 short of 20 million
global total, still.
