Google flights will start showing people the carbon footprint of their flights. Talking with @lourdesgnavarro on @NPRWeekend, I offer 2 reasons why this is a good idea -- and 1 reason it's not! npr.org/2021/10/10/104…
Good reason #1 - simply making people aware of how many calories they're eating, kilowatts they're using ... or carbon they're burning ... causes many to reduce our consumption. Just knowing what we're doing can motivate change. Exhibit A: behavior.rare.org/wp-content/upl…
Good reason #2 - responsible consumers will be able to recognize and reward companies that are using waste-based biofuels or electric short haul flights as their carbon emissions will be much less than their competitors washingtonpost.com/news/energy-en…
(and as this catches on more widely, it might possibly spur the laggards in the industry to catch up. One can hope :)
So why is this negative? Well, two reasons actually. First, some could assume a small reduction in carbon from choosing a better flight means that's all the change they need to make: and it's certainly not. We need system change at every scale.
And second, it could continue the trend of pushing the responsibility from entire industries onto the consumer: fostering a sense of individual guilt while the corporations continue to profit. businessinsider.com/fossil-fuel-co…
Overall, I think it's a net +. Most don't realize that flying is a huge source of emissions and this will make it clear. But knowing there's a problem is just the first step. We need action, and we don't have a lot of time. That's why initiatives like @flyingless are important.
What do YOU think? What pro or con for this new move did I miss?

AMAZING NEWS: an atmospheric and an ocean modeller have been awarded the Nobel Prize in Physics for "physical modelling of Earth's climate, quantifying variability and reliably predicting global warming"
🙌🙌🙌🙌🙌🙌🙌🙌🙌 (thread)
I first learned about Manabe & Wetherald's research as an undergraduate student in the class that I originally took as a breadth requirement while completing my degree in astrophysics .. but which ended up completely changing the trajectory of my life. journals.ametsoc.org/view/journals/…
Using early computers (like these ones) they were able to turn the basic equations of non-linear fluid dynamics into code that was able to represent the general circulation of the atmosphere on a rotating sphere... the origin of "GCM" = general circulation model.

The question is not, can we afford to stop using fossil fuels. The question is, how can we afford NOT to?

The other day, I decided to conduct an experiment. I set a timer for 3 hours and counted how many times I was publicly shamed here on twitter during that time. The answer? 12. And since then I've counted dozens of examples of others being shamed, as well. (thread)
Just under half of mine came from people on the right-hand side of the political spectrum, using the tried-and-true denial technique, “impossible expectations” ... i.e. you’re only allowed to talk climate action if you essentially stop breathing & live off the grid. No surprise.
But the other half came from people who were clearly very concerned about & invested in climate change. Something I said or didn’t say had violated their 10 Commandments of Green Living, and they wanted to make sure I knew it.

Good news for today: "The global pipeline of proposed coal power plants has collapsed by 76% since the Paris Agreement in 2015, bringing the end of new coal power construction into sight." Here's what needs to happen next ... (see next tweet) e3g.org/publications/n…
The lions' share of remaining carbon emissions come from a handful of dirty coal plants. smithsonianmag.com/smart-news/fiv…
Where are the world's coal plants? Primarily in the eastern US, China, India and Europe. carbonbrief.org/mapped-worlds-…

This is a REALLY good idea. Social media is almost singlehandedly responsible for the spread of dangerous conspiracy theories, from covid to flat earth to climate. They need to acknowledge it and take responsibility to address it. @jack @LinkedIn @YouTube @Facebook @Twitter
Because I’m a scientist, I want to be clear that the statement above is not just my opinion. There is peer reviewed evidence for it. For example, on Twitter: news.mit.edu/2018/study-twi…
Flat earthers: “we provide evidence for … conversion after multiple exposures to Flat Earth YouTube videos on & the crucial role YouTube played in their conversion process, suggesting the platform is potentially a strong avenue for changing beliefs.” tandfonline.com/doi/abs/10.108…
