Ten years ago, this only applied to people who reject the science of climate change. Now, it applies just as much to people who are very worried about climate change - and while I completely sympathise with the fear that drives us, turning on each other is not the answer 😰

I don't block people for what they say: I block them for how they say it. If someone can't express their opinion without being rude or mean, or without ridiculing, smearing, or misrepresenting me or someone else who's trying their best, then I don't want it in my timeline.

Fascinated that this article doesn't mention climate change but does say the coal industry contributed to the flooding through strip mining and mountaintop removal.

And to those who say, “doomerism will wake people up!” I have some important information: the vast majority of people are already worried, but only a tiny fraction are activated. More doom won’t do it: they need rational hope powered by efficacy. For more, read this thread:

What we most lack is "efficacy" - the simple belief that if I/we do something, I/we can make a difference. And how does efficacy grow? By understanding both the personal (not distant or remote) risk of climate impacts and the role each of us can play in catalyzing climate action.

I don’t know who needs to hear this (the entire climate movement apparently) but you can be glad that some good climate stuff has been proposed AND critical of the way this bill mostly cuts out frontline communities and ignores the timeline of the climate crisis at the same time

Actual climate scientists are clear: we are *not* doomed. It is *not* too late. We can stop climate change, and have already done a lot of work to do so. Don’t listen to the “it’s too late” nonsense. It’s not true, and is intended to scare you — not inform you.
Quote Tweet
Your regular reminder that, no, we are not all doomed, and climate meltdown can be stopped. But it’s up to us, and depends on how fast we can take action to cut emissions. We’ve made some progress in recent years, but still have a long way to go: nature.com/articles/d4158

"This bill is a compromise.... It is also a historic achievement for the climate left & a tribute to both its moral fervor & its political realism. Climate is a top-shelf political concern b/c it has been pushed there" – w/ an excellent take

Yikes, . You’ve done some great work but boosting inaccurate defeatism is both bad for public trust and harmful for climate action. If it’s unavoidable, why are the scientific and activist communities working our butts off to stop it? Why not boost those voices instead?

This statement is entirely untrue and extremely unhelpful, especially on the verge of breakthrough climate legislation that can limit planetary warming below the 1.5C/3F danger limit. Says Expert. (see: washingtonpost.com/outlook/2022/0 & @CoveringClimate: coveringclimatenow.org/event/press-br)

If you put solar ☀️ panels on your house, your neighbors are far more likely to put solar panels on theirs, too. That’s the power of “behavioral contagion." Here's how Dr. Katharine Hayhoe () says it could help save the planet:

How climate change affects heat waves & eight ways they affect us:

How does climate change affect heatwaves? A thread. 1 - As the planet warms, extreme heat now begins earlier in the year and stretches later. In the 1960s, the US heatwave season was about 25 days. By the 2010s, it was nearly 70 days. Source: epa.gov/climate-indica

“the “knowledge deficit paradigm” made us approach climate change […] as if they were STEM issues. But they are worldview issues. And the most advanced tool we have to change worldviews—to transform people’s attitudes, values, and structures of perception—is called the story”
