Exponential Progress in Addressing Climate Change
There is a race between the exponential impacts of climate change and the exponential progress of technologies to address it. The former head of UN climate change, Cristiana Figueras, and other speakers discuss personal stories and tested solutions to tackle climate change. The need to reduce greenhouse gas pollution is emphasized, with CO2, methane, and nitrous oxide identified as major contributors. The energy sector, accounting for 76% of emissions, and agriculture, contributing 12%, are highlighted as areas for change.
The Power of Exponential Change in Renewable Energy
Exponential change in renewable energy and associated technologies, such as solar, wind, and battery, is highlighted. The cost of solar has declined rapidly, surpassing experts' predictions. The potential for exponential growth in electric vehicles is explored, along with the need for infrastructure, collaboration, and capacity building. Abundant, sustainable, and cheap energy sources, including solar and wind, are discussed, with a particular focus on Chile's success in green electricity and green hydrogen production.
Resilient Communities and Sustainable Farming
The importance of building resilient communities and sustainable farming practices is emphasized. Economic inequality and climate change are linked, with marginalized communities being most vulnerable to climate impacts. Efforts in Detroit to create sustainable and resilient neighborhoods, such as the Circle Forest, are showcased. The Whitaker family's sustainable rice farming techniques, which reduce greenhouse gas emissions and water use, are discussed. The goal of making the US rice industry the most sustainable in the world is highlighted.
The impacts of climate change are growing, but so are the world's attempts to stop them. Hosted by Manoush Zomorodi of the TED Radio Hour, this special TED documentary examines the rapid technological revolution underway — and the real possibility of a better future for all. Featuring urban planner Anika Goss, scientist and carbon expert Julio Friedmann, UN Climate Chief Simon Stiell, auto industry sustainability leader Cynthia Williams, and multi-generational farmers Jim and Jessica Whitaker, as well as interviews with architect of the Paris Accords Christiana Figueres, former UN Climate High Champion Nigel Topping and many more.
