Literally, when it does rain, it pours!

Warming atmosphere fueling heavier U.S. rainfall and rising flood risk, AccuWeather analysis shows

A new AccuWeather study of more than 60 years of rainfall records shows U.S. precipitation totals are flat, but heavy downpours and hourly extremes are increasing, raising the risk of flooding, damage, and economic losses.

By Monica Danielle, Sep 19, 2025

"It’s not raining more across the United States, but when it rains, it’s falling harder, faster and in more extreme bursts. That’s the finding of a new AccuWeather analysis of more than 60 years of weather records, which reveals a striking shift: National rainfall totals remain statistically flat, yet the number of heavy downpours and hours with extreme rainfall have increased sharply.

"These changes are fueling greater flood risk, straining infrastructure and threatening communities nationwide. "

Methane leaks from dormant oil and gas wells in Canada are seven times worse than thought, McGill study suggests

Methane emissions from Canada’s non-producing oil and gas wells appear to be seven times higher than government estimates, according to a new study led by researchers at McGill University. The findings spotlight a major gap in the country’s official greenhouse gas inventory and raise urgent questions about how methane leaks are monitored, reported and managed. “Non-producing wells are one of the most uncertain sources of methane emissions in Canada,” said Mary Kang, Associate Professor of Civil Engineering at McGill and senior author on the paper. “We measured the highest methane emission rate from a non-producing oil and gas well ever reported in Canada.” Methane is a potent greenhouse gas. Over a 20-year period, it traps about 80 times more heat in the atmosphere than the same amount of carbon dioxide. It’s also associated with air pollution and health risks.Kang’s team directly measured methane emissions from 494 wells across five provinces using a chamber-based method and analyzed well-level data such as age, depth and plugging status. The national emissions estimate they arrived at – 230 kilotonnes per year – is sevenfold higher than the 34 kilotonnes reported in Canada’s National Inventory Report. The study was published in Environmental Science & Technology. There are more than 425,000 inactive oil and gas wells across Canada, most of which are in Alberta and Saskatchewan. This means that the number of measured wells is very small, at only 0.1 per cent. “One surprising finding was just how much the drivers of emissions varied between provinces,” said Kang. “We thought geological differences within provinces would matter more, but the dominant factors appear to be at the provincial scale, likely due to variations in policy and operational practices.” The results reveal that a small fraction of wells – especially unplugged gas wells – are responsible for the vast majority of non-producing well methane emissions. Kang says targeting these high emitters would be an efficient way to reduce emissions. “Rather than just measuring more wells at random, we can use well attributes to identify where emissions are likely to be highest, and focus monitoring and mitigation efforts there,” she said. The study serves as a reminder of the need to rethink how old wells are managed. “There’s potential to repurpose these sites in ways that generate funding for long-term monitoring and emissions reduction,” said Kang. "Many of these sites can be transformed to produce clean energy, such as wind, solar, and geothermal," said Jade Boutot, a PhD student in Kang's lab and co-author of the study. The researchers emphasize that improving methane data is critical to meeting Canada’s climate targets. “If we don’t have accurate estimates of methane emissions, we can’t design effective climate policies,” Kang added. About the study Sevenfold Underestimation of Methane Emissions from Non-producing Oil and Gas Wells in Canada by Louise Klotz, Liam Woolley, Bianca Lamarche, Jade Boutot, and Mary Kang was published in Environmental Science & Technology.

Sweating to shivering: Study finds rapid swings in temperature have increased

Flips between warm temperatures to cold and vice versa have become quicker, more frequent and more intense in recent decades, a new study shows.

"A September heat wave switching into a snowstorm over one day in the Rocky Mountains. Winter snowfall suddenly melting and saturating fields of dormant crops, before refreezing and encasing them in damaging ice. Early spring warmth prompting plants to blossom followed by a cold snap that freezes and drops their petals.

"Rapid temperature change events like these have increased in frequency and intensity over recent decades, a new study found.

"The transition periods for these abrupt temperature shifts have also shortened, according to the study, published Tuesday in the journal Nature Communications.

"Because the quick changes in temperature give communities and ecosystems little chance to respond, they may pose greater challenges than heat waves or cold snaps alone, said #WeiZhang, an assistant professor of climate science at Utah State University and one of the lead authors of the study.

" 'The impact could really be cascading on a different level,' he said.

"The researchers warned these temperature flips could have damaging effects on people and natural #environments, including destruction of #crops, harm to #ecosystems and strains on #PowerInfrastructure. And #LowIncomeCountries, where there is less access to weather forecasting and infrastructure is less resilient, are more vulnerable.

"The researchers examined temperature data from 1961 to 2023 to identify global patterns in sudden weather shifts, where temperatures in an area either jumped from cold temperatures to warm or plunged from warm to cold within five days. They found that instances of these flips increased in more than 60% of regions they surveyed.

"The largest increases in frequency were observed in South America, West Europe, Africa, and South and Southeast Asia. Some areas, including the polar regions, showed different behavior and experienced fewer events.

"While the climate mechanisms driving changes to these temperature-flip events are not yet fully understood, Zhang said, there is a significant trend showing that these events are becoming more frequent, stronger and quicker in many areas of the globe."

Temp got up to 28C around 20mins ago, now it's raining and feels much cooler, but still heading to a top between 38C and 42C.

#WeatherWeirding at it's very best.

It's Dec. in New England. Yesterday's high temp was near 60 degrees F. Today's low temp? 18 degrees F.

From over 4 weeks with no measurable precipitation to over 2 inches of rain in 24 hours.

This is what climate change looks like, even in places well away from the coast.

Here is where much MA food is grown. We've already lost all stone fruit crops twice in 8 years w/extreme weather.

A local farmer's entire cranberry crop wiped out by insects this year.
