I used to have this pinned on my (defunct) twitter account, so will repeat it here:
Don't think about climate change as something we succeed or fail at. It's not binary. Every tonne of carbon emissions makes the problem worse, so everything we do to avoid those emissions helps. Never stop trying!
One thing worth remembering as people migrate from Twitter is that no, they're not fascism apologists for having spent so long over there. Many of them are marginalised and have built entire communities on Twitter - think about what it takes for disabled, immunocompromised, queer, BIPOC, or trans people to say goodbye to their support systems. Many people rely on the visibility that Twitter afforded them for mutual aid support or work; myself included.
