"Broken record: Atmospheric carbon dioxide levels jump again"
"Carbon dioxide levels measured at NOAA's Mauna Loa Atmospheric Baseline Observatory peaked at 424* parts per million in May, continuing a steady climb further into territory not seen for millions of years, scientists from NOAA and Scripps Institution of Oceanography offsite link at the University of California San Diego announced today. [*Correction: Due to a typo, the original version of this release said the peak was 432 ppm. The correct value is 424 ppm.] Measurements of carbon dioxide (CO2) obtained by NOAA's Global Monitoring Laboratory averaged 424.0 parts per million (ppm) in May, the month when CO2 peaks in the Northern Hemisphere. That is an increase of 3.0 ppm over May 2022, and represents the fourth-largest annual increases in the peak of the Keeling Curve in NOAA's record. Scientists at Scripps, which maintains an independent record, calculated a May monthly average of 423.78 ppm , also a 3.0 ppm increase over their May 2022 average. Carbon dioxide levels are now more than 50% higher than they were before the onset of the industrial era."
Weather Outlook Through Midday Wednesday
Here's the Weather outlook through Midday Thursday, which shows spotty showers and storms developing across the Region on Wednesday & Thursday. Some of the storms could produce locally heavy rainfall, but the heaviest appears to be mainly west of the Twin Cities.
Extended Precipitation Outlook
The extended precipitation forecast through the week ahead shows pockets of heavier rain possible with some of the thunderstorms through the end of the week. Much of the thundershowers look to remain west of the Twin Cities.
Twin Cities Weather Outlook For Wednesday
The weather outlook for the Twin Cities on Wednesday, June 7th shows mild temps with readings warming to near 80F in the afternoon. Dewpoints won't be quite as highs as they've been with even lower dewpoints north and east of the Twin Cities.

A Summer of Heat, Drought and Smoke Brewing?
By Paul Douglas
Spring 2023 has been surreal. A late start with slush and ice well into April. A few glorious May days quickly overshadowed by plumes of smoke from Canadian wildfires. Early record heat across Canada has created tinder-dry conditions -at last report over 200 fires were burning. The amount of land burning so early in the summer season may be unprecedented and it shows no signs of slowing down.
NOAA predicts warmer and drier than average for Minnesota the rest of June, and gazing at the models that's not hard to believe. An El Nino warm phase in an overheated Pacific Ocean correlates with warmer, drier weather over the northern tier of the US; wetter for the southern US. A summer of heat, drought and smoke? It's looking that way.
The rain just isn't materializing the way the models keep predicting - everything is drying out close to home. An early shower gives way to a cooler breeze with comfortable 70s this weekend.
The wild card is smoke from Canadian blazes. If it gets bad I can strap on my N95 mask.

"Ozone layer recovery delayed, surface UV radiation continues to rise, finds study"
"According to a new study published in Advances in Atmospheric Sciences, the ozone isn't healing as quickly as expected, leading to higher levels of surface ultraviolet (UV) radiation in recent years. Despite projections that the ozone layer would fully recover by mid-century, researchers found rising UV radiation levels in the tropics and northern mid-latitudes after 2010, posing risks to human health and the environment. "Our analysis shows disturbed ozone levels and enhanced surface UV radiation for more than a decade after 2010," said lead author Yan Xia of Beijing Normal University. "The slower recovery of stratospheric ozone is largely unexpected." The team analyzed satellite data and model simulations to assess long-term changes in ozone and surface UV levels around the globe. "We observed a decrease in ozone levels and an increase in UV radiation over latitudes between 30°S-60°N after 2010," Xia said. "Especially in the Northern Hemisphere, the rising magnitude of surface UV radiation from 2011 to 2020 reached 0.5-1.4% per year—this should not be neglected."
"8 ancient 'zombie viruses' that scientists have pulled from the melting permafrost"
"Scientists are discovering and resurrecting ancient viruses trapped in permafrost and frozen remains. Here are 8 'zombie' viruses that scientists have pulled from the permafrost. Locked away in frigid Arctic soils and riverbeds is a world teeming with ancient microbes. Bacteria and viruses that existed thousands of years ago are frozen in time inside prehistoric layers of permafrost. Warming temperatures could cause much of the ice to melt and unleash these microbes from their frosty prisons. Once free, unknown pathogens could infect humans or other animals. "The risk is bound to increase in the context of global warming, in which permafrost thawing will keep accelerating, and more people will populate the Arctic," Jean-Michel Claverie, a computational biologist at Aix-Marseille University in France who studies ancient and exotic viruses, told CNN."
"Arizona Drought Pushes Phoenix to Hit Pause on Construction Projects"
"Arizona officials may not be able to approve new construction in some of the fastest-growing parts of the Phoenix metropolitan area that rely on groundwater in response to dwindling supply. the Associated Press reported. The Associated Press reports that Arizona Governor Katie Hobbs made the announcement this Thursday in response to a new report from the Arizona Department of Water Resources (ADWR). The new report outlined how the groundwater supply in Arizona is going to continue declining without further intervention. Demand for almost 4.9 million acre-feet of groundwater could be unmet in the Phoenix area over the next 100 years. It's a significant amount because a single acre-foot of water is enough water for about two U.S. households in a year, according to the ADWR. About 80,000 unbuilt homes on sites that have a "Certificate of Assured Water Supply," which is used by the state's water agency to regulate water, will not be paused. Those sites have proven that they can provide water well into the future. "This pause will not affect growth within any of our major cities where robust water portfolios have been proven to cover current and future demands," Hobbs said this week, according to AZFamily."
