I’ve learned from Dr. Trenberth’s excellent articles, YouTube lectures and interviews for literally decades, yet sometimes his words, and gaps, frustrate me to no end.
Instead he went vague on us and blamed it on a random “weather situation,” whatever that is. He avoided the term Jet Stream until late, almost in passing. Nor did he acknowledge the findings of Jennifer Francis and others who are actively studying our increasingly chaotic jet streams as they unavoidably transition into a new warmer global regime.
Then I folded it up and walked away from this project. Just what I wanted, add Kevin Trenberth to my list of insulted and pissed off scientists whom I actually admire.
In the Gulf we have a tropical wave looking like it’s following Harvey’s path and my disappointment and critique won’t let me be, I need to get this out and explain it to the best of my abilities.
Wouldn’t “… but they’re bigger and more intense in a warming climate system.” be more vividly explanatory?
6:15 - CBC Clip from August 28th:CBC announcer: A lot of people are asking is climate change a factor and how much (referring to Harvey)?
CBC Meteorologist responds:
“Well we can’t take this entire event and connect it to climate change. But part of the reason why hurricane Harvey has already been so devastating is because it’s being forced to sit and spin off the coast.
That in part is connected to these blocking systems to the north including a big high pressure system sitting right over British Columbia, and that’s forced Harvey to sit in place not allowing it to move forward or northward out of the hardest hit regions and more and more climate studies are connecting these blocked weather patterns with a jet stream that’s getting stuck in place thanks to a warming climate. It’s not moving weather systems forward in time.
That's part of new research that climate scientists are looking at and that is the case with Harvey being forced to sit off that coast meandering in place until that high pressure ridge over B.C. finally moves out on Wednesday night that will finally allow Harvey to move inland hopefully giving some relief for the second half of the week.”
