The graph shows Angstom got his calculations wrong because he was unaware that the absorption wavelength widens with the density of the gas. This means the rising CO2 levels have a significant impact he was unaware of, even if already saturated in a narrower band.
"Have you actually been to Korea?"
Yes
Then you would know three things,
a. There is no such country
b. Only North Korea borders China and China has no significant coal power stations on the border.
c. China has some of the strongest exhaust pipe emission controls that were introduced in 2014 and have built the newer supercritical power stations. The bulk of their pariculate air pollution is transport and cities
Sorry, wrong again. That only tells you how polluted the air is,not how DARK it is.
GET IT???
Yes, I chose the option of particulate air pollution.
It's only below the level at THIS DATE in 2012. Nowhere near the record summer low.
You are desperate to choose 6 weeks of a year when the Arctic was hit by a huge storm. This is the ultimate in cherry picking.
Let's expand things.
2019 was lower than 2012 in Jan, Feb, Mar, Apr, May Jun, Jul and is now much lower than 2012 in October with the month not yet finished. Sea surface temperatures are currently 2C higher and the gap is now over 900,000 km2.
This matters, multi year ice is gone, if a similar cyclone had hit the pack this year then the low for a few weeks in 2012 would be gone and the reality of the situation is this will happen again at some point in the future. We are no longer looking at a solid multi year mass piled up against the north of Greenland, this year there was the rarity of open water and a small sailing boat was able to make the trip around the north of Greenland.
No, you are. The reality is that there is no climate emergency, no crisis, no reason to think added CO2 will be anything but beneficial.
Yet you have failed to provide one shred of evidence to support this.
We have a feedback loop already happening, the lack of sea ice in the summer is allowing warmer waters to enter the Arctic basin from the Atlantic and the Pacific, the open sea is absorbing heat that ice previously reflected. Each year the freezing season moves a little later and progresses a little slower, this is why this year's ice extent is now much, much lower than 2012.
This image of the Bering straight in winter I posted on another thread shows how the extent is being reduced by the additional warmth in the ocean
I don't know when the Arctic will go ice free in the summer, as 2012 shows that is very much in the hands of the weather during August when the ice pack is thin, but each year the chances increase and I would be surprised if we waited more than 30 years on current trend.
Nope. It indicates the bottoming-out of a cycle, not a continued downtrend.
We are currently 600,000 km2 lower than 2018, that's nearly 10%, and at this point in the season 2018 was 700,000 km2 lower than 2017. What you are showing is a clear denial of the evidence in front of you. There is no guarantee next year will be higher or lower than this but it is highly likely that it will begin with the lowest ice extent in modern records.
