The climate crisis is happening all around us. As tech workers, we can use our skills to take and accelerate climate action.

Scientists no Longer Find Twitter Professionally Useful, and have Switched to Bluesky

Synopsis Social media has become widely used by the scientific community for a variety of professional uses, including networking and public outreach. For the past decade, Twitter has been a primary home of scientists on social media. In recent years, new leadership at Twitter has made substantive changes that have resulted in increases in the prevalence of pseudoscience, conspiracy theory, and harassment on the platform, causing many scientists to seek alternatives. Bluesky has been suggested as a good alternative to Twitter, but the phenomenon of academics switching social media platforms has not previously been studied. Here we report on the results of a survey distributed to scientists on Twitter and Bluesky (n = 813). Results overwhelmingly confirm that changes to Twitter have made the social media platform no longer professionally useful or pleasant, and that many scientists have abandoned it in favor of Bluesky. Results show that for every reported professional benefit that scientists once gained from Twitter, scientists can now gain that benefit more effectively on Bluesky than on Twitter.

We asked our climate reporters to highlight one idea for positive change. We got a chronicle of global transformation

There are countless initiatives around the world that can inspire people and spur them into action. Amid the devastation of the climate crisis, our journalists strive to highlight these stories of hope

Appropriate Technology, Permacomputing, Post Growth, and Ecomodernism.

To adapt to the changing climate, we need to radically rethink how and why we do the things we do. From technology, to social movements, to economics. The world is at stake. And we can change it.

People care about climate change, injustice, and humanitarian crises. The challenge is not apathy but capacity: sustained engagement with large-scale problems is psychologically costly, and social media architecture often amplifies awareness while providing few pathways to meaningful action.

The climate crisis reveals that our civilization has never really been organized around science, contrary to the usual Enlightenment narrative. It is organized around capital. Science is embraced when it serves the interests of capital, and is often ignored when it does not.— Jason Hickel (@jasonhickel) January 6, 2022
