Some of you are familiar with forecasts of increased and lengthier drought in arid regions as seen in the climate models going back to the 1980s. Those forecasts cover a span of many decades and extend into the next century. The mean over the next 100 years will see expanded and worsened drought in already arid regions.
But breaks in the trend will be showing up periodically due to increased blocking and stagnation in the jet stream. When the jet stream weakens/slows, it “buckles” more, sagging into blocked patterns which greatly inhibit west-to-east winds aloft. This weakening is tied to arctic warming.

As predicted, the loss of highly reflective ice on the Arctic Ocean, and the thinning of ice due to a shorter freeze season to be replaced by dark blue heat absorbing waters for more of the year has led to a rate of warming in the arctic that is twice that of the rest of the globe. What was not originally foreseen in the arctic warming was the frequent weakening in the polar jet stream that would result. The lessening of the temperature gradient between the high latitudes and mid-latitudes does now more often lead to blocking patterns. Much of this work was pioneered by former Rutgers researcher Jennifer Francis, now at Woods Hole.
When these blocks develop, lengthier periods of more extreme conditions can develop in parts of the world. As I’ve written before, blocking led to the stalling of Hurricanes Florence and Harvey, producing catastrophic flooding when they drifted inland. Even as I write this article on Monday, this morning’s upper air shows a high amplitude flow with partial blocking.

Make no mistake, this severe weather potential is a weather event. But the evidence of a strengthening tie-in between the mean warming climate and individual extreme weather events has become more nearly conclusive in many cases, with much peer-reviewed evidence to support the link. The most glaring example of such a connection between climate and weather comes in the increased number of extreme rainfall events. The warming oceans and atmosphere have increased evaporation, putting more water vapor into the lower atmosphere.

Not that many years ago, it was thought connecting the mean warming climate and individual extreme weather events was very difficult at best. Now, another sub-discipline called Attribution is showing many – not all – extreme weather events and their increased numbers have a visible link to climate change, most especially the accelerated warming in the arctic.
Climate change: the answer to everything!
Psoriasis? Climate change.
Hangnail? Climate change.
Pie crust not flaky? Climate change!
drought = global warming
increase rain = global warming
need to raise taxes = global warming
Ah yes, the All Purpose explanation for every event: It’s Climate Change (’cuz we can’t say Global Warming anymore since the East Anglia guys got caught fudgin’ the data...sigh)!!
So now they have a thin little thread to tie their latest Biblical ranting (Plague! Pestilence! Famine!) to everything Climate: “Attribution”.
Lemme know when Jenny can run her simulation with the right boundary conditions down to the kilometer scale and show it all works.
Why so wet? It’s a phenomenon called “spring”.
Its 67 deg in Phoenix right now.
Not complaining but its a bit cold here right now.
There is no bad weather event that cannot be blamed on “climate change”, specifically of the manmade variety. It’s amazing!
“The warming oceans and atmosphere have increased evaporation, putting more water vapor into the lower atmosphere...” thus bringing more rain & snow and cooling the earth. As the earth cools, ice will form in the polar regions and elsewhere where it is stored until the additional water vapor is needed again. It’s a self-regulating system.
We’re in the middle of a Colorado snowstorm.
Always always remember that when a science article is written by a journalist - heh!
Well, guess when any article on anything is written by a journalist - heh!
We’re not talkin’ the right side of the Bell Curve.
more opiate for the urban population who rarely go outside.
watch them run, run , run.
in circles.
bring on the totalitarian controls!( sarc.)
Kind of old-fashioned in the uniform, don’t you think?
No social-media-conscious democrat would wear that uniform today.
Climate change, huh?
Please provide a technical definition of “climate” without reference to ‘weather’.
Well shoot! It’s raining right now in Seattle. I mean what the frick? Rain in May? Are you fricking kidding me?
Want to save the earth? Stopping migrations, global movement of goods, and air travel would be a real good start.
Global warming alarmists have evidently come out of their winter hibernation. It’s that time of the year again.
May is also the height of tornado season. Therefore, Good Morning America starts every morning with on the scenes reports from OK, KS, TX.
In another couple month we will be onto hurricane season in the southeast.
Then we will be back in fire season California, the Pacific NW and Canada.
I will wager that sometime in July/August it will get to 115 degrees in AZ.
I think they’re referring to those of us who have massive record rainfall over the entire year. It has been unbelievable and leaving us with highly saturated ground, drowning some things and leading to floods more otherwise.
But the monthly/season record is still from 2003 here, and I will never forget it. Wow, endless dreariness and rain every day for 2 months!
