BHS post was taking a random warm day and saying “this doesn’t usually happen and AGW is real and we’re all gonna die” as a proof for his position. That would be the same as a person taking a brutal cold shot and saying global cooling is happening, it’s just not a good argument to use no matter which side a person stands on in the debate.
Have you read the paper you linked? I’ve never heard of that author before but wow it is fraught with serious grammatical errors that make it incredibly difficult to understand what they’re trying to say at times or simply worded incredibly odd. Not sure if it’s a language barrier/translation issue or what but here are a few examples of what I mean below.
“The extreme weather phenomena had been recorded over the globe and became more frequent through the last decades. The stability conditions like as, blocking systems, fluctuations in precipitation and temperature, strong and extreme frequency of hurricanes, heat waves, droughts, flash floods, extreme weather events and global warming through the year.”
“One can conclude that the global warming causes extremely increasing anomaly of global annual geopotential height. So that the stability conditions over the globe was changed through the last three decades and extreme weather phenomena existed.”
A much better paper imo is
this one here which makes a similar analysis but doesn’t have the weird grammatical/language issues.
