Significant changes in the northern jet stream has caused serious problems for Europe and South Asia:
Unusual jet stream behavior has been recorded every three to five years since 2000 — in 2003, 2006, 2010, 2015 and 2018 — turning what scientists initially thought could be an isolated abnormality into what appears to be a pattern, [Jeff Masters, co-founder and director of meteorology for Weather Underground] said.
What is surprising to scientists now is that the wavier-than-normal jet stream has returned for a second year in a row — the first time that has been observed, said Kai Kornhuber, a climate scientist at The Earth Institute at Columbia University in New York City.
“I wouldn’t have expected this situation to return so quickly after the extreme summer last year,” Kornhuber said. “It gives me the chills to see this evolving in real time again. It’s a really worrying development.”
This weather pattern brought temperatures over 45°C to France earlier this week:
The highest reliable June temperature previously recorded in France was 41.5°C on 21 June 2003. The country’s highest ever temperature, recorded at two separate locations in southern France on 12 August during the same 2003 heatwave, was 44.1°C.
“At our local Potsdam station, operating since 1893, we’re set to break the past June record by about 2C,” tweeted Stefan Rahmstorf, of the Potsdam Institute for Climate Impact Research. Eastern parts of Germany, including Berlin, are already experiencing their hottest June on record.
“Weather data show that heatwaves and other weather extremes are on the rise in recent decades,” he said. “The hottest summers in Europe since the year AD1500 all occurred since the turn of the last century: 2018, 2010, 2003, 2016, 2002.”
Monthly records were now falling five times as often as they would in a stable climate, Rahmstorf said, adding this was “a consequence of global warming caused by the increasing greenhouse gases from burning coal, oil and gas”.
And the band played on...
Articles that piqued my interest this morning:
Back to writing software.
Climate change has arrived with a splash in Illinois. Unusual rainfall combined with bad timing on this past winter's freeze-thaw cycle means we may not have much of a soybean crop this year:
The soggy conditions will likely delay planting, again. Dillon, the Machesney Park resident, lives across the river from a plot of farmland he said has been barren for the last five years due to persistent flooding.
"You used to be able to raise corn in that field," Dillon said. "In the last five years, I don’t know if he’s had a crop in there or not. It’s always flooded. It’s too wet to plant, too wet to harvest."
The torrential rainfall and runoff has been known to wash fertilizer, animal waste and other pollutants from farm fields into waterways. It can also cause sewer systems to back up.
In either scenario, the untreated water can contain an unsafe amount of nitrogen, which can render the water dangerous for consumption. Fertilizer and sewage can also stimulate algae blooms that can degrade water quality. This, in turn, raises the costs associated with treating water, the new report says.
On Wednesday, [Illinois governor J.B.] Pritzker toured flooded areas of Winnebago and Stephenson counties. While no deaths related to the flooding have been reported, state and local officials say nearly 200 people have been evacuated.
“These are some of the highest river levels this area has seen in more than three decades, and I commend local emergency managers, law enforcement, fire and the volunteer organizations that have come together to keep people safe and preserve property,” Pritzker said in a statement. “For downstream communities that will be impacted by flooding in the days and weeks to come, I know that many groups are already preparing to help their neighbors. While we know that rebuilding will take a lot of time and work, we are committed to being your partners for the future.”
The Tribune explicitly tied these events to climate change in its headline.
The Tribune reports that today ends Chicago's second-wettest spring ever, the wettest May ever, and the only second month in recorded history (out of 1,770 months) to have 21 days of precipitation. This might become the new normal: 9 of the last 10 Mays have had above-average precipitation.
Lake Michigan, the inland sea ten blocks from where I'm sitting, has near-record water levels:
Lake Ontario, downstream, has swelled by almost a meter in the last two months to all-time record levels:
So not only has all this rain has caused massive flooding in rivers throughout the Midwest, but the high lake levels prevent rivers from draining and have accelerated wetland erosion along the shore.
Another thing: all this fresh water drains out through the St Lawrence Seaway right into the North Atlantic. Combined with meltwater coming off Greenland, that surge of lighter, fresher water is slowing the thermohaline circulation that brings warmth to Northern Europe. So as most of the world gets warmer, Europe could get a lot colder in the next century.
Said any climate scientist ever interviewed this past year, "We told you so 30 years ago."
As Chicago finishes the wettest May in history, Bloomberg points out that all the rain has caused serious problems with Illinois agriculture:
Rabobank is predicting an unprecedented number of unplanted acres of corn, the most widely grown American crop. A Bloomberg survey of 10 traders and analysts indicates growers could file insurance claims for about 6 million corn acres they haven’t been able to sow, almost double the record in 2013.
Corn futures surged more than 20% to a three-year high over the past few weeks on fears farmers wouldn’t be able to get seeds in the ground ahead of crop-insurance deadlines. So-called prevented plant claims reached 3.6 million acres in 2013, according to the U.S. Department of Agriculture’s Farm Service Agency.
Yesterday Chicago set a few weather records: wettest Memorial Day ever recorded, tied for most days in May with measurable prediction (18), tied for most days in May that have had more than 7.6 mm of precipitation (10), and up to the 3rd wettest month of May (186 mm). And we have more rain predicted tonight.
Warmer air holds more moisture. The atmosphere worldwide is warmer. QED.
Burger King's brand implosion aside, other, more important news came out in the last couple of days:
- This morning, UK Prime Minister Theresa May announced she would step down on June 7th, having lost the confidence of the right-wing crazies holding her majority together. The likely outcome of this will be Prime Minister Boris Johnson, who is actually less popular than May, forcing a general election through incompetence by the August bank holiday.
- The heads of NOAA and NASA have raised the alarm that the proposed 24 GHz frequency band proposed for 5G wireless will mask the existing 23.8 GHz frequency of passive microwave energy which weather forecasting systems need to actually forecast weather.
- Since February 2017, when he took his first of over a hundred golf trips as president, Donald Trump has cost us more than $100 million playing golf.
- San Francisco's KPIX-TV Broadcast Operations Manager Eliot Curtis apparently gave himself an LSD trip while repairing a 1960s-era synthesizer.
Must be Friday.
Due to climate change and gentrification, rat sightings in North America have gone up:
New York has always been forced to coexist with the four-legged vermin, but the infestation has expanded exponentially in recent years, spreading to just about every corner of the city.
Rat sightings reported to the city’s 311 hotline have soared nearly 38 percent, to 17,353 last year from 12,617 in 2014, according to an analysis of city data by OpenTheBooks.com, a nonprofit watchdog group, and The New York Times. In the same period, the number of times that city health inspections found active signs of rats nearly doubled.
Milder winters — the result of climate change — make it easier for rats to survive and reproduce. And New York’s growing population and thriving tourism has brought more trash for rats to feed on.
Chicago — crowned the nation’s rat capital in one study — has more than doubled its work crews dedicated to rats, who set out poison and fill in burrows in parks, alleys and backyards. It also passed ordinances requiring developers and contractors to have a rat-control plan before demolishing buildings or breaking ground on new projects.
Yah, thanks for that "rat capital" thing, New York Times.
Rats don't bother me, despite their urine often containing deadly bacteria. They clean up after us, feed crows and coyotes, and spread disease less than other local rodents. (Rabbits have made Parker sick a lot more often than rats.) And squirrels? Just ask a moose.
Meteorologist Brian Brettschneider has figured out a road trip route that keeps you at a (normal) temperature of 21°C for a whole year:
For his data, Brettschneider pulled daily “normal” high temperatures from the National Centers for Environmental Information and Environment Canada. “Normals are a smoothed average of all days between 1981 and 2010,” he explains. He took temperatures from every weather station in the U.S. and Canada and “just connected the dots,” he says. “There were some decisions I made to maximize area and connectivity.”
Forging a route was no easy task, as weather stations hit normal high temperatures of 70 degrees over vast amounts of time and space. This visualization gives an indication of how America’s daily 70-degree highs shift throughout the year:
Might be a fun retirement trip. And it only requires driving 21,295 km.
Yesterday evening, I needed to wear earmuffs and gloves when walking Parker because of the 7°C weather. Yes, it's the middle of May, but we've had a really screwy spring this year.
Today I don't need gloves. Our official temperature bloomed from 8°C to 26°C in the past six hours. Even close to the lake, where I live, it's already warmer outside than inside—and I had the heat on briefly this morning!
Today the forecast looks hot and humid, before temperatures plunge again Sunday night. Then hot again next weekend. And maybe seasonally appropriate when meteorological summer begins two weeks from today.
Who knows. Welcome to Chicago in spring.
