This exchange is quite telling: Mike E. 14 hr ago edited 14 hr ago You maybe missing the trees for the forest. Global or local mean or median temperature is a nebulous (no pun intended) indicator. It's the increases in daily weather variance, incomprehensibly-fast melting of major glacial masses, rising sea levels, and frequency and intensity of storms, fires, famines, and species' extinctions that are the "forest". These are consequences of anthropogenic GHGs that reduced Arctic sea ice (nearing an inevitable blue ocean event) and increased global sea thermal energy absorption which destabilized the jet stream from more predictable cycles. GHGs lead to a -11 F snowpocalypse in Austin, megadrought in US West and SW, "Hurricane Alley" shifting eastward, 100 F in the high Arctic town of Verkhoyansk, water trains of India, and slumping and melting of Siberian and other permafrost areas releasing absurd amounts of methane.
author creon levit 7 hr ago The variance (locally) is shown in the plots. What do you see re: variance?
"Incomprehensible" glacier movement? As I understand it nine time in the life of the human species the glaciers have advanced to cover much of N. America and then retreated to where there was little or no polar ice at all.
Frequency and intensity of storms? I suggest downloading the data on all hurricanes for the last ~100 years (as long as they've been recorded) from the NOAA national hurricane data center. I did that. I plotted it. Guess what I found?
Fires... I lived in Napa California during the big Napa fires. How much was due to climate change, and how much was doe to terrible forest management by the forest service and the state? (don't thin the forests, don't clear dead trees, etc).
Species diversity is very complicated. A whole different matter. So much to say at another time.
Famines? Have you looked at famines vs. time for the last 1000 years? Other than the global covid mismanagement disasters of 2020-2022 (lockdowns, etc) famines are becoming a thing of the past - though if we continue killing our soils with mono-crop soy, etc they will recur.
Arctic (and Antarctic) sea ice is another deep topic.
Austin was a fluctuation. They happen. Don't kill your local electric utilities - you may want them when things get dicey (or icy :).
Look into the history of draughts (and floods) over the last 200 years in the W and SW US.. Write a post and send me the link.
You raise a lot of points. (or less politely, you are shifting the goalposts 12 times in one paragraph). I am just plotting local temperatures for 75-100 years. Nothing more.
After that exchange I'm fairly convinced this article wasn't written with the goal of 'doing science' however misguided. |
