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

Stewardship of global collective behavior

Collective behavior provides a framework for understanding how the actions and properties of groups emerge from the way individuals generate and share information. In humans, information flows were initially shaped by natural selection yet are increasingly structured by emerging communication technologies. Our larger, more complex social networks now transfer high-fidelity information over vast distances at low cost. The digital age and the rise of social media have accelerated changes to our social systems, with poorly understood functional consequences. This gap in our knowledge represents a principal challenge to scientific progress, democracy, and actions to address global crises. We argue that the study of collective behavior must rise to a “crisis discipline” just as medicine, conservation, and climate science have, with a focus on providing actionable insight to policymakers and regulators for the stewardship of social systems.

The limits of social media as a source of political information during routine and crisis times across 17 countries

Recent studies on political knowledge suggest people learn little about political events and societal issues from social media. Potentially, social media are a more effective source of information ...

Leveraging agency for climate change mitigation

Climate debates often frame individual behaviour and systems change as distinct pathways to action. We suggest that social change arises from individuals’ agency within their roles in societal systems, and that this agency should be actively leveraged to achieve meaningful climate change mitigation.

The Nightmare of Eternal Spring: Why Social Media Can't Survive on "Niceness" Alone - Nightflight

Interdependent Thoughts – by Ton Zijlstra

Still, many questions have global aspects. Our information networks, our trade routes, our dependencies are truly global. Because of it many of our issues, including climate emergencies, are global in both their roots and consequences. We all suffer from small earth syndrome these days, as I phrased it in 2010 at the SHiFT Conference, where everything anyone of us does reverberates around the world because we are continuously bumping into real global limits, Club of Rome style.

What can a technologist do about climate change? A personal view.

This started with a tweet. I’m embarrassed how often that happens.

The climate crisis is a self-destructive war, with aggressors and victims

Following news on social media boosts knowledge, belief accuracy and trust

Many worry that news on social media leaves people uninformed or even misinformed. Here we conducted a preregistered two-wave online field experiment in France and Germany (N = 3,395) to estimate the effect of following the news on Instagram and WhatsApp. Participants were asked to follow two accounts for 2 weeks and activate the notifications. In the treatment condition, the accounts were those of news organizations, while in the control condition they covered cooking, cinema or art. The treatment enhanced current affairs knowledge, participants’ ability to discern true from false news stories and awareness of true news stories, as well as trust in the news. The treatment had no significant effects on feelings of being informed, political efficacy, affective polarization and interest in news or politics. These results suggest that, while some forms of social media use are harmful, others are beneficial and can be leveraged to foster a well-informed society.

You see the climate destabilization, biodiversity loss, resource scarcity, toxic bioaccumulation, and climate injustice happening all around us. You aren't the type to bury your head in the sand or shrug it off and so you roll up your sleeves. But where to start? How to ensure your work doesn't...
