Weather

Anyway, extreme weather swings are more common as climate change progresses.

I called this leftist fearmongering brainwashed lie out as bullshit. I got a private message that this was exceedingly rude and got my post deleted. So to a bunch of "Texans" fighting back against the lies of the left is rude. Maybe I can get banned like I asked to back when this here group chose to be politically correct.

Your comment also said 50% don't agree with that statement...that makes half of the people right, and half wrong...It's obvious which side you're on. A bit more research might change your mind. Not all news sources are based on actual science, and Texas' economy is geared towards fossil fuels, so they have a vested interest in them persisting. FWIW, methane is worse and persists longer, and Texas burns off a huge amount of that or leaks out that is visible from sensors in space rather than capturing it, which doesn't help matters at all.

Since about the mid-1700's, Glacier Bay's glaciers have retreated over 65-miles. Back after the last mini-ice age, you couldn't see Glacier bay as it ended about where the bay opening is today. https://www.nps.gov/glba/learn/natur...al-history.htm

Just one example of many. If you read through the thread, the look back at 600K years of ice cores from Antarctica show a major increase of CO2 starting just after the industrial revolution where we started to use lots of fossil fuels (mostly coal at the beginning), with the highest slope of increase in that 600K year period, and with them now higher than we can find in that time period. And, the slope is still rising faster than any other records we can find.

The temperature here has been dropping all day, and currently at -2F, expected to get to -13F with wind gusts up to 40mph...not nice! It should be back to 44F for the high on Sunday after a frigid Saturday. Luckily, no precipitation, course, the colder the air, the less moisture it can hold, but whatever is there tends to fall.

Winds get powered by both temperature and pressure differences. FWIW, the Arctic temperatures have risen 4x faster than much of the rest of the world; a significant amount of the sea ice has both melted, and is returning later, and is thinner while being less reflective, so absorbs more of the incoming solar. Since the ocean covers so much of the world, it absorbs more of the heat and CO2, which is changing the pH, which is also messing with the shells of various species. The polar vortex is the high altitude, normally fairly consistent circular wind around the pole, but the jet stream can be influenced by it and to it, and that can allow a surge of cold air to drop south and is what's happening now. This also happened last year when it wobbled south into Siberia, causing record breaking cold spells, and record-breaking heat waves when it wobbled back.

We're still learning how this all works, but since we have been monitoring and can assess it, the oceans' temperatures, the CO2 levels, and average air temperatures are rising. The growing season is longer, tropical insects are living further north, warm water fish are being found further north, the lobsters are moving north and further out to sea, the maple trees that make New England a good area to produce maple syrup are being stressed, and the production is dropping, the season is occuring earlier, and is shorter. Check out the king crabs off Alaska...they've essentially flown the coop. The migrating birds are being stressed, as the clues they use to decide when to migrate (length of day, sun position, etc.) aren't corresponding to their normal food sources peaking as they arrive (insects and plants/seeds). Changes have occurred previously, but they were much more gradual, and things had a chance to adapt.

At a little after 5pm, the wind gusted to 100-mph at the observatory atop Mt Washington, and a wind chill of -101F...it was probably higher, the charts don't go any higher...

It's down to about -10F. I went to the mailbox, and glad it's not far! It was damn cold out! The winds weren't that bad...maybe gusting to 20-mph, but it's supposed to get colder and windier before it warms back up. Most places will, if they haven't already, set a low temperature record. Around here, most places have been keeping records for at least 160-years, and some, more than that. But, one record low, there have been way more record highs this year and the last.

Best part of that report is living most of a thousand miles south of there.

[jadnashua]

White snow covered areas reflect 85% of the incoming solar radiation. The darker open ocean absorbs 90% of the incoming solar rays. The sea ice coverage is melting sooner and over larger areas and refreezing later.

As a result, the Arctic is warmer than the average temperature rise for most of the rest of the world.

[jadnashua]

When sea ice forms, some of the salts are ejected which is denser causing that water to decend which then flows away from the poles, helping to moderate temperatures across the globe. Around both poles, there is less and less sea ice forming which is one reason the poles are warming faster. You may have heard of the "screaming fourties'" which is a circular wind stream of rough weather circling the globe. It's not only a wind current (up north It's called the polar vortex but land masses disrupt it more than the southern one) it drives a deep ocean current that has slowed about 15% in the last 20-years or so we've been studying the area. One research group has returned to the same area three times in the last five years and found the sea ice has retreated about nine further miles each time. The sea surface temperature has risen about 3C in the last 20-years. That part of the world is very hostile to investigate and the length of time the summer lasts when you can gain access is short, so we have to rely more on remote sensing, which isn't as comprehensive. Trying to put all of the information together is tough, but it doesn't look good.

And just think, only about 12000 years ago or so we were still in an ice age... it's almost as if the world is coming out of the ice age still... wild I tell ya. I for one and glad it's warming, damn the cold.

Yea, there's a little sarcasm thrown in there, but it's 100% facts as well...

Was 45 this morning and will be almost 80 when I leave work today. Think I'll go fishing this afternoon.

[jadnashua]

Animals, plants, insects, and people can handle slow changes...the world in the last 200-years or so is changing far faster than any period we've been able to discover in every way we've looked. We've analyzed ice cores that cover the last 600,000-years...the trends in the last 200 or so show a much more rapid change than that large, earlier period. That's the issue.

I look at the top of the page to remind myownself that this is s'posta be a weather thread. Maybe we need a climate-change thread, too?

We're gonna have a couple of barely freezing nights this week, after a couple of lovely, high 70s days. Then maybe it won't freeze any more 'till December, and that'll be fine with moi. But it's usually another full month before we can comfortably rule out any freezing nights in my area. Just hafta keep looking for buds on the Mesquite trees for the final verdict.

[jadnashua]

Average high where I live this time of year is in the low, mid-30's...it got to 58 today, and Boston set a record of over 60...weather is part of climate...the climate is the average and trend, weather is the current that can vary radically from day-to-day.

[Mathman]

I admire you tenacity Jadnashua. And agree totally.
Thanks for the info.

[jadnashua]

FWIW, Boston averaged over 3-degrees higher than normal the last month, while setting both a low and a high temperature record...

One area likely lost their entire peach crop, as the warm weather caused the buds to start to grow, and the rapid, deep-freeze killed most of them.

The maple syrup producers started collecting weeks earlier than the norm, and the season pretty much ends once the nights regularly stop going below freezing, shortening the season. This is both part of the weather and the climate.

Folks in Florida can tell them all about that, Jim, and I think, they, as well as most of us, know that's part of the weather and the climate.

Whatever you believe, great. But “global warming” is too political to keep going on and on about it. No more, please.

Thank you.
