Another impact of growing extreme heat = chronic pain. Worse for those living/working in rural America. theconversation.com/chronic-pain...
“Across the U.S., 44,004 wildfires have ignited so far this year, scorching more than 4.8 million acres…well above the 10-year-to-date averages of 34,340 fires and 3.63 million acres burned, marking the most active season at this point in the year since 2022” www.foxweather.com/weather-news...
Today's headlines aren't separate stories. Wildfires. Smoke. Cyclospora. Line 5. They're reminders that the health of our environment shapes the health of our communities. Clean air. Safe food. Fresh water. The science is clear. The solutions exist. Now we need the will to act.
This is what human-caused climate change looks like - look at all the uncontrolled wildfires in Canada. www.cbsnews.com/news/wildfir...
The two largest reservoirs in the U.S. now have less water in them than all the way back to 1957 when the Glen Canyon Dam was being constructed behind what would become Lake Powell. The Southwest Megadrought is getting scary folks. qanr.usu.edu/coloradorive...
The USA is looking pretty darn dry and drought challenged in many places. These hot temps aren't going to help... droughtmonitor.unl.edu/CurrentMap.a...
Sea level rise is very real and getting worse. www.washingtonpost.com/climate-envi...
Michigan utilities have to do better, so do those of many other states. “It just feels really reckless and inhumane, especially when we’re looking at utility profits on the other side.” www.mlive.com/news/2026/04...
“We will inspire but ultimately, we will always choose Earth. We will always choose each other." apple.news/Aj2RVaaI6QhO....
This picture has to be AI generated, but it's a good one. This report is a good reality check - follow the money, as they say... The energy transition is for real, going more slowly in the US than many other countries. CCS & green H don't look like winners. assets.jpmprivatebank.com/content/dam/...
Looks like the record heat in the West is melting an already low snowpack fast with peak snow water equivalent has coming earlier than ever before - over 2 weeks earlier than the median peak timing. Distressing to say the least. nwcc-apps.sc.egov.usda.gov/awdb/basin-p...?
Yet more record heat. This is what human-caused climate change looks like: www.nytimes.com/2026/03/18/w...
New analysis confirms global warming is accelerating. "all data sources agree: the warming rate has been far higher during the last decade than any previous." agupubs.onlinelibrary.wiley.com/doi/full/10....
Western US snowpack is still looking BAD. Hope for snow, but plan for low river flows and severe wildfire risk.
Blood Moon setting over Lake Superior. Another Great Lake looking great!
Michigan going electric... Fun facts I just learned: EV & plug-in hybrid EV registrations in MI jumped 126% from 2023 to 2025, & the number of public DC fast chargers in the state jumped 84% from 2024 to 2025. Pretty easy (& more affordable) to ditch the old internal combustion vehicle in MI
Battery storage costs keep plummeting, as installations rocket up. One bright spot for the U.S. power grid. www.canarymedia.com/articles/bat...
A big majority of Americans favor the regulation of CO2 (the most impactful greenhouse gas) as a pollutant. Strongly supported by science too!
Water security is at serious risk in much of the world, and climate change is increasing the risk in many places. theconversation.com/the-world-is...
Asia has the biggest water stress problem, but isn’t alone in needing to use water more sustainably. www.washingtonpost.com/climate-envi...
Climate change and unsustainable water use is speeding a global water crisis - and increasing conflict as well. www.washingtonpost.com/climate-envi...
Here's one of the latest forecasts for the current CO River water year. Super bad. The river allocation system is clearly breaking, and climate change isn't helping at all. coloradoriverscience.org/Woodson_Lees...
While the Pacific Northwest (and soon NCal) gets hammered by climate change supercharged rain, snow and flooding, the US SW megadrought is at 26 years a counting. No relief in sight. droughtmonitor.unl.edu/CurrentMap.a...
There is a lot of drought currently in the USA. droughtmonitor.unl.edu/CurrentMap.a...
Another one of those days when the Great Lake region looks especially great…as climate change takes a toll further south. www.washingtonpost.com/climate-envi...
A reminder - a majority of Americans in every state are aware of climate change and are worried about what it means for the future. climatecommunication.yale.edu/visualizatio...
