Must We Hack Our Planet’s Atmosphere?
The failure of recent efforts to curb greenhouse-gas emissions has built some momentum toward expanding research on geoengineering options. Although everything possible must be done to shift to a sustainable and energy-efficient economy – along with changing to simple life-styles and putting a cap on the world’s population – all this will not be enough to eliminate the danger of runaway climate change.
Somehow, we have to find a safe way to remove the huge amount of excess carbon dioxide in our atmosphere. To analogize, diet and medicine alone won’t cure our planet; surgery will also be required. Too much CO2 in our atmosphere not only contributes to global heating, sea-level rise, more severe storms and desertification; it has also caused a 30% increase in ocean acidification, and this too threatens the life of everything on Earth.
Bill Gates Sees Climate Change as Important Global Problem
Here are two opposing articles on the Bill Gates TED Talk on “Innovating to Zero.” Our opinion, if Gates thinks climate change is important, we should all feel a little more hopeful. His take on this issue may not be all we could wish for, but as he learns more about how very serious is the global treat we face and how extraordinarily complex an adequate solution must necessarily be, he may stop thinking in terms of simplistic formulas and quick technological fixes. He’ll see that like with climatic systems, many positive feedback loops are inherent in the development of economic, technological and social solutions, and these must not be ignored. The big industry in bio-fuels that has sprung up in response to the need for energy efficiency is a case in point.
Someday Soon: A Hybrid Electric Car That Can Help Power Your Home
An advancement in hybrid electric vehicle technology is providing powerful benefits beyond transportation.
Researchers at the Department of Energy’s Oak Ridge National Laboratory have designed, fabricated and demonstrated a PHEV traction drive power electronics system that provides significant mobile power generation and vehicle-to-grid support capabilities.
“The new technology eliminates the separate charging mechanism typically used in PHEVs, reducing both cost and volume under the hood,” said Gui-Jia Su of ORNL’s Power Electronics and Electric Machinery Research Center. “The PHEV’s traction drive system is used to charge the battery, power the vehicle and enable its mobile energy source capabilities.”
Providing more power than typical freestanding portable generators, the PHEV can be used in emergency situations such as power outages and roadside breakdowns or leisure occasions such as camping. Day-to-day, the PHEV can be used to power homes or businesses or supply power to the grid when power load is high, according to Su.
The charging system concept, which is market ready, could also be used to enhance the voltage stability of the grid by providing reactive power, Su said.
Has a “Convergance of Catastrophes” Already Begun?
James Howard Kunstler examines the critical importance of oil in our global economy and then anticipates the cascade of catastrophic consequences when – not if – supply fails to meet demand. After a century of profligate use of this energy-dense resource, he contends that we are within a decade of experiencing an oil shortage: for transportation, industry, heating, plastics, fertilizers, pharmaceuticals and all the countless products essential to our modern lives. In other words, our energy-devouring civilization has been accelerating entropy.
Cleaning Up the Excess CO2
The other way to reduce the air’s excess CO2 is to unbalance the carbon cycle, typically by preventing some of the CO2 captured by photosynthesis from going back into the air when cells decompose. One has to stash dead biomass where the air can’t get to it. While sealed landfills help, it is only the ocean depths that would appear to have the capacity to draw down all of the CO2 that we have added since 1750.
Final Episode of BBC World’s “Hot Cities” Available
Los Angeles is one of the most polluting cities in the world thanks largely to its love affair with the car. It is a city built on consumption. Each person produces around 20 tonnes of emissions per year – twice as much as anyone else. Now they are about to reap what has been sown. In LA there has been a big increase in wildfires, water supplies are under threat, rising sea levels could have a massive impact on LA’s huge port and destroy thousands of homes. “Hot Cities” goes to LA just as the city launches its adaptation strategy.
Too Stupid to Take Action on Climate Change? It’s Time to Get Smart and Get Started
In addition to reducing greehouse gas emissions to zero as quickly as possible and developling more carbon sinks, such as planting a many trees as possible, we must concurrently begin research and development of ways to artificially remove carbon from our atmosphere. The excess carbon we have to rid our planet of is the equivalent of the mass of over four Mount Rainiers.
Increased Interest in ‘Artificial Trees’ for Removal of Carbon from Atmosphere
Many climate scientists calculate that the world has only a few decades to reduce emissions before there is so much carbon dioxide in the atmosphere that a dangerous rise in global temperature is inevitable. The authors of this report say that geo-engineering of the type they propose should be used on a short-term basis to buy the world time, but in the long term it is vital to reduce emissions.
William H. Calvin: Putting the CO₂ Genie Back in the Bottle
This presentation by Dr. Calvin was made at the University of Victoria BC on June 18th. The event was sponsored by the BC Chapter of the Sierra Club of Canada. Dr. Calvin is introduced by Dr. Colin Campbell, Science Advisor to the Sierra Club of BC. At the end of the five minute introduction, click [...]
