Hi madmechanic,

Always great to read you here, especially when you bring up climate topics like this!

I will try to have more comments later this weekend beyond this(you know how I get carried away).

This is appears to be another example of using an extreme(weather) and trying it to climate change. The odd thing is that this person explains it with totally natural oceanic and other phenomena and is making a case for this NOT to be climate change.

They also mention benefits to the warming, so I give them credit for being somewhat objective.

On the ozone hole that developed in the 1970's . No, we don't know that. It's when the technology advanced for us to detect it for the first time. It appears likely that it's been there since before humans existed and it comes and goes every year seasonally. 

It does fluctuate however, as this scientist mentioned but in our extremely  limited experience/time in being able to measure it, we can't say what it was like in the past and really have no idea if anomalies are just normal fluctuations(which seems more likely  than not). 

Here are some recent discussions in where Antarctic Ice is a main topic.

Their final statement:

"Under climate change, extreme events are predicted to increase in frequency and severity, and Antarctica is not immune."

This is misleading because some extreme events will decrease with global warming.

Heavy rain events will be higher(warmer air holds more moisture). And obviously heat waves will be higher.

But violent tornadoes will continue to decrease(reduction of temp gradient with latitude) and so will extreme cold and cold in general. 

Hurricanes are uncertain. Wildfires are worse, mostly because the increase in CO2 has massively increased the fuel load but thats not climate/weather. Droughts are NOT increasing or getting more severe on the real planet, just more attention to them as they move around, get worse, then get better as they have always done and in the same places.
