When we think of #food, we often aren’t paying attention to soil, but it’s actually what sustains our global food system.
Unfortunately, #ClimateChange, unsustainable farming practices & more are degrading soil around the world.
I don’t get to see each episode of Serving Up Science until they are published, but I like this new video. And I’m so glad they let me talk about soil health. https://youtu.be/FnOHwq6iSpk?si=5umwoGQU7DFrdhCD

1/ What can you, a software engineer, do to fight #ClimateChange? My initial answer continues to be politics (https://codewithoutrules.com/2019/09/10/software-developers-climage-change/) but I now have a secondary answer.
There's a lot of software out there and it's ludicrously inefficient. Not because people don't care, but because no one bothered to look, or the cost is spread across millions of people, or because no one has time (open source! it's fun.)
Let me give you some examples—
What can a software developer do about climate change?

Emissions from computing are apparently higher than for air travel, and that’ll only go up in the coming decades.
“As a society we need to start treating computational resources as finite and precious, to be utilised only when necessary, and as effectively as possible. We need frugal computing: achieving our aims with less energy and material.”

The current emissions from computing are almost 4% of the world total. This is already more than emissions from the airline industry and are projected to rise steeply over the next two decades.arXiv.org

Many believe a significant way to address #climatechange is to 'eat local,’ but that’s not always true. The impact all depends on the kind of #food + how & where it’s produced.
Some foods require fewer resources (water, energy) in some parts of the world. Season can be important. Overall, transportation has a much lower carbon footprint than land use change. And so on.
So instead of ‘eat local,’ let’s go with ‘eat thoughtfully.’ https://ourworldindata.org/food-choice-vs-eating-local
You want to reduce the carbon footprint of your food? Focus on what you eat, not whether your food is local
'Eat local' is a common recommendation to reduce the carbon footprint of your diet. How does the impact of what you eat compare to where it's come from?Our World in Data
Physicist John Tyndall is often credited w discovering the greenhouse effect, which he wrote about in 1859.
But Eunice Foote published a paper - 3yrs earlier - demonstrating how atmospheric water vapor & CO2 affected solar heating. She theorized that heat trapping gases in Earth’s atmosphere warm its climate.
Tyndall was widely read. And Foote, being a woman, wasn't even permitted to present her own work. http://www.climate.gov/news-features/features/happy-200th-birthday-eunice-foote-hidden-climate-science-pioneer #history #science #ClimateChange

Tim Flannery's message to all: rise up and become a climate leader – be the change we need so desperately
What makes a great climate leader and why are we not seeing more of them? I’ve been searching for good examples of climate leaders. This is the subject of our new documentary, Climate Changers.The Conversation
Environmental groups sued the Bureau of Land Management and won, for making their 20 year plan for western #Colorado without consulting with tribes nor accounting for the impact their 20 year plan would have on #ClimateChange.
They rewrote their plan and have two options to choose from. One option, Alternative F, is actually pretty damn good (especially compared to the original)
We have until November 1st to comment and advocate for Alternative F

According to OurWorldInData, 80 billion animals are slaughtered for food each year.
The scale of what eat (& waste) is massive, which contributes to #ClimateChange & degrades the environment.
In the US, we consume ~280lbs (127 kg) /person/year (not including fish & seafood).
Beef has the most significant environmental impact & Argentinians consume 104lbs (47 kg) of beef/person/year. #food
Scientists in China have found evidence that our ancestors were almost entirely wiped out ~1 million years ago.
Why? #ClimateChange
While not every expert agrees, the research is intriguing & @Carl_Zimmer has the details: https://www.nytimes.com/2023/08/31/science/human-survival-bottleneck.html?smid=nytcore-ios-share&referringSource=articleShare #science
Globally we produce A LOT of #energy, but did you know the majority of fossil energy gets wasted? In the US alone, two-thirds of that energy is *wasted* as heat.
As Hannah Ritchie has pointed out, we don’t actually need to produce a low carbon equivalent of all of the coal, oil & gas we currently use.
That means we can decarbonize quickly by being less wasteful & more efficient. #ClimateChange #science
In my opinion, Earth is better with emperor penguins on it. So I truly hope we do all we can to prevent their extinction. #ClimateChange #nature

in 2013, coal generated 175 times as much electricity as #solar power in the US. Within a decade, in 2022, coal was generating less than 5 times as much electricity (incl. estimated rooftop solar).
So far this year, coal has generated slightly more than twice as much electricity as all solar.
Coal is dying here but needs to die even faster.

I wish I didn't have to tell you about this again, but I do. It's not being reported much in the news — and you know why?
Because it's not 'new' (the origin of the word 'news'), it's old. This has been going on for months now, and corporate news outlets are simply tired of reporting it. But it is still happening.
Canada's boreal forests are burning up.
At least 1100 fires are active, more than 700 out of control. Over 13 million hectares have been burned so far, with no end in sight. It's an unprecedented climate and environmental disaster.

It’s worth noting that by Fall of 2012, the majority of both Republican & Democrat voters acknowledged #ClimateChange is occurring. But not the majority of all politicians.
Back then, I ran large public opinion surveys out of UT Austin & it was the first time citizens from both parties agreed. (Here’s a 2015 SciAm piece w totals https://blogs.scientificamerican.com/plugged-in/over-3-out-of-4-americans-now-acknowledge-climate-change-is-occurring-including-the-majority-of-republicans/)

NYT’s opinion writer Paul Krugman is declaring #climate is now a culture war issue 🤔
I worked in the U.S. Senate ~20 years ago. Covered climate as a journalist. Cofounded an NGO focused on science policy issues during elections. Am finishing a dissertation on how Congress has made decisions about #science policy for the last 1/2 century - with climate as a central theme.
This isn’t new. #ClimateChange has *always* been a culture war issue.
Climate change threatens 771 endangered plant and lichen species: Despite the risk, very few of these species have recovery plans that directly address climate change

The right's cries for "ideological diversity" sound fair to well-meaning people who believe in good-faith debate as a way to arrive at the truth. But truth is not the goal here; the goal is power.
