The problem with the glacier discussion is the implication that climate change is predominantly man made. The second problem is the presumption of infallible science. My favorite lake in IA was carved by a glacier 14,000 years ago. Maybe the ancient Egyptians with their space alien technology were the ones to start manmade global warming.

The denial that humans are impacting the atmosphere is equality flawed. The one thing I know for sure is that every pending global disaster has thankfully been averted by implementation of more taxes and regulation that concentrates power amongst the loudest voices.

Yes…coverage, but NOAA also says actual total ice increased to a record in 2014. Amounts have bounced around since then.

From the journal of climate that detailed that record:Sea ice has also received attention because of the very different changes that have occurred in the Antarctic region (specifically in the Southern Ocean surrounding Antarctica), where sea ice coverage has increased rather than decreased since the late 1970s (Stammerjohn and Smith 1997; Zwally et al. 2002; Parkinson and Cavalieri 2012), reaching a then-record maximum in September 2012 (Turner et al. 2013) and a new maximum in September 2014. These sea ice increases in the Antarctic have not been as large as the sea ice decreases in the Arctic and have not been as widespread geographically. In fact, sea ice extent has decreased substantially in the Bellingshausen and Amundsen Seas region, immediately to the west of the Antarctic Peninsula (where there has been pronounced warming; Chapman and Walsh 2007), despite increasing overall in the Antarctic (Parkinson and Cavalieri 2012; Turner et al. 2013).
Irrespective of the cause of the increased Antarctic sea ice, the contrast between decreasing sea ice coverage in the Arctic and increasing sea ice coverage in the Antarctic has led at times to unnecessary confusion. Most notably, it is sometimes quite erroneously thought that the increases in Antarctic sea ice cancel out the decreases in Arctic sea ice. To quell that serious misconception, this note presents the global results, generated simply by adding the hemispheric results and calculating the resulting trends

sooooooo....how 'bout those payback days?

“Arctic sea ice ranks as the third highest in the last 10 winters”

Not saying the Earth isn’t warming…just that things bounce around. Don’t think we are in a death spiral quite yet.

That's fair. Wasn't sure what you were arguing

More humans die from cold than heat annually. Many parts of the world stand to benefit from increased temperature. Deserts will shrink, verdant, arable land will increase in size.

Despite the alarmism, I don't see the prices of beachfront homes in Martha's Vineyard decreasing.

And yes, the only way to avert catastrophe is surrendering our freedoms to the UN, eating bugs and stripping away all disinformation that doesn't fit the narrative.

I am going to go out on a limb here and say No.

First off - are extreme turbulence events really increasing? If we have millions more people flying each year we would expect to hear about extreme turbulence more often - even if levels stayed the same.

Second - With modern media trying to fill 24-7 news coverage we hear about everything. Turbulence injuries are great for media, scary and millions of viewers fly every year. How often do you think turbulence injuries rose to national media coverage in the 1970s, or even the 1990s?

I would say with improved detection capabilities and better aircrew training, turbulence injuries by passenger miles flown are down, waaaaay down, but as with many things today the media will distort anything for improved ratings. For example with the door plug blowing off the 737 the media goes into hysterics and people assume flying is more dangerous today when in fact it is much safer. Although Boeing seems to be going out of its way to help sensationalize aircraft safety.

How much air traffic growth has taken place in areas prone to turbulence like the ITCZ?
