The question is not, can we afford to stop using fossil fuels. The question is, how can we afford NOT to?
Just a reminder ... rollingstone.com/politics/polit…
And don't forget ... science.org/news/2016/08/j…
And here's another illustration of what fossil fuels cost us, this time from the UK. Source: newstatesman.com/energy-climate…

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/…
They were not the first to calculate how much the earth would warm as we increased CO2 by burning fossil fuels, though. That was done in the 1890s by another Nobel-winner, Svante Arrhenius; a distant cousin of @GretaThunberg. rsc.org/images/Arrheni…

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…

So delighted to see #TIME100 recognize pioneering scientists @FrediOtto and @gjvoldenborgh for their work on the cutting edge of extreme weather attribution: putting numbers on how much worse climate change made a given hurricane, heatwave or flood. 👏👏👏time.com/collection/100…
Their work makes climate change up close and personal. I wrote this op-ed with Fredi a few weeks ago, when the air outside my family's home was choked with wildfire smoke and she was checking on her family's safety after the devastating German floods. nytimes.com/2021/08/17/opi…
If you'd like to understand the science behind how they put numbers on exactly how much more likely, stronger, or more damaging climate change made a certain event, I highly recommend @FrediOtto's engrossing book. greystonebooks.com/products/angry…
