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

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

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

Knowledge infrastructures for the Anthropocene

The technosphere metabolizes not only energy and materials, but information and knowledge as well. This article first examines the history of knowledge about large-scale, long-term, anthropogenic environmental change. In the 19th and 20th centuries, major systems were built for monitoring both the environment and human activity of all kinds, for modeling geophysical processes such as climate change, and for preserving and refining scientific memory, i.e. data about the planetary past. Despite many failures, these knowledge infrastructures also helped achieve notable successes such as the Limited Test Ban Treaty of 1963, the ozone depletion accords of the 1980s, and the Paris Agreement on climate change of 2015. The article’s second part proposes that knowledge infrastructures for the Anthropocene might not only monitor and model the technosphere’s metabolism of energy, materials and information, but also integrate those techniques with new accounting practices aimed at sustainability. Scientific examples include remarkable recent work on long-term socio-ecological research, and the assessment reports of the Intergovernmental Panel on Climate Change. In terms of practical knowledge, one key to effective accounting may be ‘recycling’ of the vast amounts of ‘waste’ data created by virtually all online systems today. Examples include dramatic environmental efficiency gains by Ikea and United Parcel Service, through improved logistics, self-provision of renewable energy, and feedback from close monitoring of delivery trucks. Blending social ‘data exhaust’ with physical and environmental information, an environmentally focused logistics might trim away excess energy and materials in production, find new ways to re-use or recycle waste, and generate new ideas for eliminating toxic byproducts, greenhouse gas emissions and other metabolites.

In the Global North we often act as if our future will be a warmer version of today: liberal capitalism, plus flood insurance, minus coral reefs. That future is a fantasy.
