For every five breaths you take, one is paying for your brain, one is paying for your liver, and another is paying for your muscles.  On average, your body spends about 1,400 calories per day just keeping you alive, even if you're doing nothing else. This helps explain why we tend to avoid unnecessary physical activity.  For our ancestors, finding food could be incredibly difficult, so they didn't waste energy. Today, even though have energy sources ready at our fingertips, we still naturally protect how we spend that energy.

With the growth of wildfires in the west, many people are very upset. That includes me. Some of the areas burning are very special to me. But I want to share some biocentric perspectives on fire that are often missing. First, as I say in this video, fires are mainly driven by climate, not fuels. That means that forest thinning and prescribed burns are, at a landscape scale, ineffective at reducing fire spread and intensity. George Wuerthner has written extensively about this. This is a very important issue to me, as fires are always used as an excuse for more logging, both for forest thinning ("fuels management") and for "salvage." Burned forests are important carbon sinks and biodiverse wildlife habitat, and should be left alone to recover naturally. Logging is never good for forests.

On the eve of the Global Climate Action Summit (GCAS), we started the conversation about how solutions could be led by states, cities, businesses and NGOs. The Paris Climate Accord was successful in bringing together the entire world around a common goal. But as Gina McCarthy points out, “We need to get together and figure out how you address and drive solutions to climate that actually end up in not just a cleaner and healthier and more sustainable world, but one that’s more just.” Join our conversation with Marisa de Belloy, Gina McCarthy, Bill McKibben, Tom Steyer and Gloria Walton This event is in partnership with Cool Effect, Capital Public Radio and in affiliation with the Global Climate Action Summit. Poverty and Climate Connection 2:59 Tom Steyer: Changing Capitalism 4:36 Bill McKibben: Collective Systemic Change 11:52 Gina McCarthy: How to be more effective 16:29 Lightning Round! 18:58

Multistreaming with https://restream.io/?ref=nVVND Our media has the power to promote positive ideas and a clear narrative, but more often than not it reinforces the polarisation that exists across the political spectrum. To avert climate change, surely we’ll need a broader consensus than already exists, at least around the solutions. So, how might we scale a new story? And what role, if any, does the world of media play? Join this broadcast to hear from: - George Marshall - Co-founder at the Climate Outreach with the aim to help people understand climate change in their own voice. George has written two books surrounding the topics of climate change, personal behaviour and psychology: “Carbon Detox” and “Don’t Even Think About It: Why Our Brains are Wired to Ignore Climate Change”. - Elizabeth Segran - Senior Staff Writer at Fast Company Magazine, writing on topics surrounding design, with a particular focus on the fashion industry. Liz is the author of The Rocket Years, which will be published in April 2020.

The unprecedented level of economic inequality in America is undeniable. In an extended essay, Bill shares examples of the striking extremes of wealth and poverty across the country, including a video report on California's Silicon Valley. There, Facebook, Google, and Apple are minting millionaires, while the area's homeless -- who've grown 20 percent in the last two years -- are living in tent cities at their virtual doorsteps.

NOTE FROM TED: TEDx events are independently organized by volunteers. The guidelines we give TEDx organizers are described in more detail here: http://storage.ted.com/tedx/manuals/tedx_content_guidelines.pdf Dr. Bill Weihl shares his perspective on how companies can change the game on climate by advocating for stronger public policy. Through his non-profit initiative, ClimateVoice, Dr. Weihl aims to mobilize the workforce to encourage companies to go "all in" on climate -- especially by using their voice and influence to support public policy, everywhere they operate. Note: References to "John" and "Hal" throughout the talk are to John Doerr and Hal Harvey, whose Countdown talk was featured before this one at the TEDxClimateChangeAI event. The referenced talk can be found here: https://www.youtube.com/watch?v=d4Cy16uOdLM Bill Weihl is the Founder and Executive Director of ClimateVoice, a non-profit initiative launched in February 2020 that is mobilizing the workforce to encourage companies to go “all in” on climate - especially in their use of their voice and influence to support public policy, everywhere they operate. Previously, Bill was Director of Sustainability at Facebook, leading work on sustainability across the company; Green Energy Czar at Google, where his team pioneered Google’s work to buy clean energy for its data centers, among other initiatives; a Professor of Computer Science at MIT; a researcher at Digital's Systems Research Center; and CTO of Akamai Technologies. Bill is on the board of directors of the Sierra Club Foundation and of Acterra, and also on the boards of WeSpire and Common Energy. He has received numerous awards, including Time Magazine's Hero of the Environment (2009), the Global Green Award for environmental leadership (2016), and the VERGE Vanguard Award (2018). This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
