Out-of-the-box climate solutions, global temperature hits record high, and the most impactful climate actions you can take

 Her newsletter this week brought this to my attention:

I love innovative and unique climate solutions. I’ve talked before about sand batteries, toilets that give students credit for the biomass (the polite term for poop) they generate, and solar panels on parking lots, but there’s a lot more out there.

There's a concert venue in an old industrial warehouse in Glasgow that since 2022 has been heated and cooled using the stored body heat of the concertgoers. “If you have a thousand people in here, that’s enough to heat 65 homes, and a lot of gas that isn’t being burnt," says geothermal entrepreneur David Townsend, who created the Bodyheat system. 
 
What if there were a way to harvest the kinetic energy that pedestrians produce by walking? There is! Piezoelectric tiles help harness energy from foot traffic. When these tiles are compressed by people stepping on them, they create electricity. A pilot study installed piezoelectric tiles in a metro station in Egypt that saw more than 57,000 passengers move through it every day. The study found that these tiles generated enough energy to power the entire metro station.

Wouldn’t it be amazing to see these technologies developed and spread across the globe?

And she continued with:

You may have seen the news this week: the Earth’s average temperature has been more than 1.5 degrees Celsius above pre-industrial levels for the past 12 months, according to the Copernicus Climate Change Service. And each of the last 13 months was the warmest on record.
 
This does not mean we've passed the threshold the world agreed to in Paris in 2015. For that to happen, the average amount of warming must stay above 1.5C for more than a decade. What this does mean, though, is that we’re closer than ever to that threshold.
 
This last year also gives us a preview of what an average year will look like if the world warms by 1.5C: a sampler, if you will, of what is to come. Over the past 12 months, we've seen a lot of major climate disasters - from Storm Daniel, which killed at least 6,000 people in Libya, to wildfires that scorched Maui, Hawaii, to record-breaking heat across South America in winter, Asia this spring, and the United States right now.
 
What this means is if we want a different future, now is the time to act. We need all voices calling for the societal change we will need to cut our emissions and invest in a cleaner, greener future! While we have not yet passed our Paris targets, the window for us to act is rapidly closing and the science is clear: every bit of warming matters, every action matters and every choice matters.

And then there's "what you can do..."

here's a..."list of the most impactful climate actions individuals can take. If you are worried about climate change and want to make a difference:

 Start a conversation about why climate change matters and what people can do about it
 Join a climate action group to amplify your voice and others
 Consider where you keep and how you spend your money (including your bank, credit card, retirement, and purchases)
 Spark ideas for change at work, school, church, or any other organization you are part of
 Hold politicians at every level accountable by voting and by telling them why climate change matters and what you want them to do about it
 Reduce your personal footprint and make your actions contagious by talking about them
