After a dozen years in the construction business, Bob Burnside wanted to build a house that would symbolize his commitment to energy efficiency. “I wanted it to be on the leading edge of what we do…(read more)
In less than 60 years Japan was able to convert its war-torn economy into a world class economy. But this rapid economic growth came at a price. The price was pollution which impacted the environment and public health. Some of the pollution-related diseases include:
This program looks at how Japan has suffered from the impact of pollution.
Humanity has yet to reach the point of no return when it comes to catastrophic climate change, according to new calculations. If we content ourselves with the existing fossil-fuel infrastructure we can hold greenhouse gas concentrations below 450 parts per million in the atmosphere and limit warming to below 2 degrees Celsius above preindustrial levels—both common benchmarks for international efforts to avoid the worst impacts of ongoing climate change—according to a new analysis in the September 10 issue of Science. The bad news is we are adding more fossil-fuel infrastructure—oil-burning cars, coal-fired power plants, industrial factories consuming natural gas—every day.
A team of scientists analyzed the existing fossil-fuel infrastructure to determine how much greenhouse gas emissions we have committed to if all of that kit is utilized for its entire expected lifetime. The answer: an average of 496 billion metric tons more of carbon dioxide added to the atmosphere between now and 2060 in “committed emissions”.
That assumes life spans of roughly 40 years for a coal-fired power plant and 17 years for a typical car—potentially major under- and overestimates, respectively, given that some coal-fired power plants still in use in the U.S. first fired up in the 1950s. Plugging that roughly 500 gigatonne number into a computer-generated climate model predicted CO2 levels would then peak at less than 430 ppm with an attendant warming of 1.3 degrees C above preindustrial average temperature. That’s just 50 ppm higher than present levels and 150 ppm higher than preindustrial atmospheric concentrations.
Still, we are rapidly approaching a point of no return, cautions climate modeler Ken Caldeira of the Carnegie Institution for Science’s Department of Global Ecology at Stanford University, who participated in the study.
Chris Malloy’s film strikes so deeply into the heart of Patagonia’s wilderness we come to feel at home there. 180° South: Conquerors of the Useless follows Jeff Johnson as he retraces the epic 1968 journey of his heroes Yvon Chouinard and Doug Tompkins to Patagonia. Along the way he gets shipwrecked off Easter Island, surfs the longest wave of his life — and prepares himself for a rare ascent of Cerro Corcovado. Jeff’s life turns when he meets up in a rainy hut with Chouinard and Tompkins who, once driven purely by a love of climbing and surfing, now value above all the experience of raw nature — and have come to Patagonia to spend their fortunes to protect it.
Quotes from the movie:
“The best journeys answer questions that in the beginning you didn’t even think to ask.”
“To love a place, you must know it first.”
“You can’t just keep trying to make a flawed system work.”
