Methane - a climate solution?

The latest IPCC assessment raised alarm about the rate at which manmade emissions are contributing to climate change. Much of the focus for action is on reducing levels of carbon dioxide, however there is a more potent greenhouse gas, methane, produced by natural and industrial p ... Show More

TED Climate: Tracking the whole world's carbon emissions -- with satellites and AI | Gavin McCormick

<p>What we know today about global greenhouse gas emissions is mostly self-reported by countries, and those numbers (sometimes tallied manually on paper!) are often inaccurate and prone to manipulation. If we really want to get serious about fighting climate change, we need a way ... Show More
