[Lex Computer & Tech Group/LCTG] Today's talk

Wed Aug 26 14:53:15 PDT 2020

I agree with George and Harry in that I enjoyed Shelly's presentation. I 
didn't realize that the object of the talk was to refute the role of CO2 
in being a cause or further catalyst of climate change (temperature 
increase), and his talk has made me investigate this topic more than I 
normally would have. While I think the role of CO2 is fraught with 
difficulty in its ascription to climate change, I don't think it's 
settled that this gas doesn't have a role, despite Shelly's presentation.

My understanding is that Shelly does believe that the climate is 
changing, but that the media, etc., saying that increased CO2 emissions 
are causing it, is incorrect. I did a little reading about the roles of 
the ozone layer and sunspots on climate change (nothing conclusive yet) 
as well as the glacial ice change in the Antarctic. There was one 
reference that agreed with Shelly that the amount of glacial ice hasn't 
changed much in the past several years, but that reference said that the 
amount of ice gained in the east of this continent was tough to measure 
and probably is insignificant when equated with the ice lost by the 
glacial calving in the west. Other, more certain of their results, 
references indicate that there is a temperature increase in the southern 
hemisphere and that the glaciers are more rapidly shifting as the ice 
melts, thereby forming under-ice rivers, in turn causing increased ice 
slippage. As I recall, there is agreement by most scientists that there 
has been an increase in the sea level in the past few years caused by 
the loss of ice at both poles. Whether this is a natural fluctuation 
that occurs over the millennia, I don't know.

Again, enjoyable presentation.
