Before checking out the new, dramatic Arctic ice video below, let's begin with a bit of good news about an emerging "greener" global economy. Since many of you missed my blog last Saturday after the 4th of July, here it is again:
Arctic Ice Situation. To me, this is the most fearsome aspect of abrupt climate change. The Arctic ice has been disappearing for decades but has picked up speed of late.
Many climate scientists agree that what is happening right now in the Arctic is quite frankly, terrifying. Some of the experts, albeit very few from mainstream science, are saying that it is likely that the Arctic will be "ice free" in summer by 2020 or sooner.
Dr. Peter Wadhams
of the University of Cambridge and
of the University of Ottawa are among the few highly regarded scientists who seem to be carefully analyzing all of the relevant data.
Now--On to that Video!
"Ice-Free Summer in the Arctic?
This frightening video was recently published by NASA and the "picture" that it conveys is literally worth a million words. It clearly shows how the older Arctic ice has almost completely disappeared during the timeframe of this video--over the last thirty-two years.
Watch how the ice ebbs and flows on a monthly basis since 1980. The last still image reveals the stark difference between Sept. of 1984 and Sept. of 2016.

The Bottom Line
. There is no question that the ice is melting rapidly in the Arctic. The question is when, or if, it will become ice-free in the summer?
My guess is that it won't happen this summer. As you can see from this chart, the last data point is for the average ice extent throughout the month of June 2018. The good news is that it indicates a larger area of coverage than the average Arctic sea ice extent for both of the two previous months of June -- 2016 and 2017.
The past two years' data points on this graph is no cause for celebration. June 2018 data is still on the steadily-downward trend-line and it doesn't tell the whole story. That's because the "ice extent" doesn't reveal the average thickness of the ice is at an all time low according to Dr. Peter Wadhams.
I continue to check the daily ice extent at nsidc.com several times a week and will give you periodic updates.
Finally, here is a great Arctic Ice "big picture" piece by Dr. Wadhams on the Yale University website
Introduction to this fine piece (Sept. 2016):
The top of the world is turning from white to blue in summer as the ice that has long covered the north polar seas melts away. This monumental change is triggering a cascade of effects that will amplify global warming and could destabilize the global climate system.
What happens next? These two BSBs (posted in June) feature credible scientists on the topic of climate change (anthropogenic climate disruption) and what it means regarding the future of humanity.
Dr. Peter Wadhams, in the first one, discusses the carbon removal remedy mentioned above; whereas Dr. McPherson, in the second, offers no optimism whatsoever.

Looking for Opportunities to Speak.
Since 2016, my research, writing and speaking has been focused on the sustainability of our ecosystem and our future as a species. With a primary emphasis on food choices, I call it the "most important topic in the history of humanity."
After all, what could possibly be more important to humans than the survival of our species?
Later this year, my co-author, Dr. Kerry Graff, and I may be speaking at a Chinese Nutrition Association event in Nanjing, China. For more info, Visit our speaking page.
