What is Earth Overshoot Day? In 8 Months, Humanity Exhausts Earth's Budget for the Year August 20 is Earth Overshoot Day 2013, marking the date when humanity exhausted nature’s budget for the year. We are now operating in overdraft. For the rest of the year, we will maintain our ecological deficit by drawing down local resource stocks and accumulating carbon dioxide in the atmosphere. Just as a bank statement tracks income against expenditures, Global Footprint Network measures humanity’s demand for and supply of natural resources and ecological services. Saving the earth one byte at a time Hopeful tourism computing? A couple of weeks a ago I interviewed Tess Brosnan, a film maker who wanted to talk about links between citizen science and hopeful tourism. This led me to read Annette Pritchard, Nigel Morgan and Irena Ateljevic’s “Hopeful tourism: A new transformative perspective” (pdf). I found myself reading while mentally replacing “tourism” with “computing”.
The Greening of the Self By Joanna Macy / filmsforaction.org Something important is happening in our world that you are not going to read about in the newspapers. I consider it the most fascinating and hopeful development of our time, and it is one of the reasons I am so glad to be alive today. It has to do with what is occurring to the notion of the self. The self is the metaphoric construct of identity and agency, the hypothetical piece of turf on which we construct our strategies for survival, the notion around which we focus our instincts for self-preservation, our needs for self-approval, and the boundaries of our self-interest. Big Ideas: Linking Water, Power, and Sewer in K-12 A Center for Ecoliteracy – San Francisco Public Utilities Commission partnership. This publication is an addition to the Center for Ecoliteracy’s suite of Big Ideas curriculum resources. It was commissioned by the San Francisco Public Utilities Commission (SFPUC) as a guide for educators, curriculum developers, and schools to engage students. It stems from the commitment of the Center and the SFPUC to nurture the next generation of environmental stewards. Big Ideas identifies key concepts that link water, power, and sewer. It highlights learning objectives that are essential to understanding the interconnectedness of San Francisco and the surrounding ecosystem.
Peak Everything: Eight Things We Are Running Out Of And Why Getty ImagesWhy is everything running out at the same time? We did a series on Planet Green where we looked at why those basic things that we take for granted, like water, food and fuel are getting expensive and scarce, all at once.Peak Corn: Blame Earl Butz. Richard Nixon and Gerald Ford's Secretary of Agriculture brought in the Farm Bill that dramatically increased the amount of corn produced in America.
Global Ecovillage Network Vison The Global Ecovillage Network envisions a world of empowered citizens and communities, designing and implementing their own pathways to a sustainable future, and building bridges of hope and international solidarity. Mission The heat is on over the climate crisis. Only radical measures will work Drowned cities; stagnant seas; intolerable heatwaves; entire nations uninhabitable… and more than 11 billion humans. A four-degree-warmer world is the stuff of nightmares and yet that’s where we’re heading in just decades. While governments mull various carbon targets aimed at keeping human-induced global heating within safe levels – including new ambitions to reach net-zero emissions by 2050 – it’s worth looking ahead pragmatically at what happens if we fail. After all, many scientists think it’s highly unlikely that we will stay below 2C (above pre-industrial levels) by the end of the century, let alone 1.5C. Most countries are not making anywhere near enough progress to meet these internationally agreed targets.
Yes, the Climate Crisis May Wipe out Six Billion People “Carbon emissions may continue to rise, the polar ice caps may continue to melt, crop yields may continue to decline, the world’s forests may continue to burn, coastal cities may continue to sink under rising seas and droughts may continue to wipe out fertile farmlands, but the messiahs of hope assure us that all will be right in the end. Only it won’t.” — Chris Hedges One thing the climate crisis underscores is that Homo sapiens are not primarily a rational species. When forced to make important decisions, particularly decisions affecting our economic security or socio-political status, primitive instinct and raw emotion tend to take the upper hand. At 4°C of warming, would a billion people survive? What scientists say. by David Spratt In a way it’s an obscene question: if the planet warms by 4 degrees Celsius (°C), would only a billion people survive and many billions perish? Obscene in the sense of the obscenity of arguing about the exact body count from a genocide. In the end it’s about the immorality, the crime, the responsibility, not the precise numbers. But it’s a relevant question, in that Earth is heading towards 4°C of warming, based on emission reduction commitments so far. The Paris commitments are a path of warming of around 3.3°C, but that does not include some carbon cycle feedbacks that have already become active (e.g. permafrost, Amazon, other declines in carbon store efficiency) which would push that warming towards 5°C.
