Don't Predict Rain During a Drought
By Paul Douglas

The worst sins a meteorologist can commit? Missing a tornado. Predicting flurries but a blizzard forms instead. Forecasting sprinkles only to wake up to a flood. Taking a vacation during a Category 4 hurricane? It's a long list.

I am reminded that weather models (and meteorologists) are still a long way from perfect And think twice before predicting heavy rain during a severe drought. Moisture that was predicted to soak much of Minnesota is staying south. The storm is tracking 200 miles farther south and so are the heaviest bands of showers and thunderstorms. The metro may see a few showers today, but NOTHING like what was predicted late last week.

Mea culpa. And thank God I'm not working at the nuclear power plant Homer Simpson recommended.

No 90s this week, just 70s and 80s with relatively comfortable humidity as Alberta Clippers push southward out of Canada. Maybe a few days of smoke but so it goes in 2023. No earthquakes, mudslides, blowing sand or storms with names. I just wish it would rain.

Climate Stories

(NOAA/The Minnesota Star Tribune)

"Do phrases like 'global boiling' help or hinder climate action?"

"Last week, United Nations General Secretary António Guterres coined an arresting new term. The era of global warming has ended, he declared dramatically, and the era of "global boiling" has arrived. You can see why he said it. July was the hottest month on record globally. Searing temperatures and intense wildfires have raged across the Northern Hemisphere. Marine heatwaves are devastating the world's third-largest coral reef, off Florida. And as greenhouse emissions keep rising, it means many even hotter summers await us. But critics and climate sceptics have heaped scorn on the phrase. Taken literally, they're correct – nowhere on Earth is near the boiling point of water. Is Guterres' phrase hyperbolic or an accurate warning? Do phrases like this actually help drive us towards faster and more effective climate action? Or do they risk making us prone to climate doomism, and risk prompting a backlash?"

"Action to protect the Arctic could slow climate change"

"As a scorching wake-up call reverberated around the globe, climate scientists urged accelerated action in the Arctic to help slow the rate of warming and keep the 1.5° C guardrail within reach. A new research report urges the countries that are members of the international group the G20, to take urgent action to preserve and understand the Arctic's role in climate warming, and highlights the urgency and necessity of immediately cutting back "short-lived climate pollutants" black carbon and methane. The report was from the ThinkTwenty, or T20, a group that is officially recognized by the G20 and brings think tanks and high-level experts to consider policy issues. As a backdrop to the T20 Summit meeting in India this week, the report – "The Consequences of Arctic Amplification in a Warming World" – explains the amplification that occurs from interlocking effects causing the Arctic to warm four times faster than the global average. Amplification has caused the Arctic's reflective sea ice to shrink and the amount of heat going into the ocean to increase, causing more ice to melt in a self-amplifying feedback loop."

"Burned by the European heat, travelers are seeking new destinations this summer"

"An unusual summer scorcher or a new normal? Some travelers aren't waiting to find out if this year's heat wave in southern Europe is an anomaly or part of a longer-term pattern caused by climate change. Tom Marchant, co-founder of the London-based luxury travel operator Black Tomato, told CNBC that his company has already seen a shift in interest from travelers hoping to avoid the searing summer heat. "We're seeing strong interest and desire to take advantage of the Scandi summer," he said. "Scandinavian destinations like Finland, Norway, Sweden, Iceland are seeing a pronounced rise from the sales front." 'Scandi summer' trend Interest in visiting the Mediterranean dropped by 10% from June to November this year, according to data published by the European Travel Commission. The summer of 2022 was Europe's hottest on record. On the flip side, summer bookings to Scandinavia are up 37% from last year, Marchant said, citing his company's data. "And we expect this will continue to climb," he said."
