New Sabin Center Report and Online Resource: Navigating State Law in Local Climate Action
-
Local governments are leaders in the fight against climate change: they reduce community-wide greenhouse gas emissions, promote renewable energy resources, and otherwise advance climate mitigation and adaptation goals. But even as many local governments have already demonstrated their capability to tackle the climate crisis, state governments can hinder those efforts by preempting local laws. Today, […]

Adopting low-cost ‘healthy’ diets could cut food emissions by one-third
Choosing the “least expensive” healthy food options could cut dietary emissions by one-third, according to a new study. In addition to the lower emissions, diets composed of low-cost, healthy foods would cost roughly one-third as much as a diet of the most-consumed foods in every country. The study, published in Nature Food, compares prices and […]

Why it’s critical to move beyond overly aggregated machine-learning metrics
by
MIT researchers have identified significant examples of machine-learning model failure when those models are applied to data other than what they were trained on, raising questions about the need to test whenever a model is deployed in a new setting. “We demonstrate that even when you train models on large amounts of data, and choose […]
