Morgan O’Donnell reviews the ways she would like to take a proactive role in the environment through work and defines the three categories of jobs that she is interested in pursuing.
The 2009 Copenhagen Diagnosis: Climate Science Report provides a critical update to the global public on the latest climate science. The purpose of this report is to synthesize the most policy-relevant climate science published since the close-off of material for the last IPCC report that supplements the IPCC AR4 in time for Copenhagen in December, 2009.
A new study by the Marine Biological Lab (MBL) of Woods Hole Oceanographic Institution (WHOI) has reported that biofuels that displace food crops may have a much bigger carbon footprint than previously thought. MBL senior scientist Jerry Melillo and his colleagues at the MBL have reported that carbon emissions from land-use change caused by the displacement of food crops and pastures by a global biofuels program may be twice as much as the emissions from lands directly devoted to biofuels production.
With global eco awareness expanding on climate issues, it is not a surprise to many that the fastest growth in CO2 levels has occurred in the last 10 years. Studies indicate that electricity generation and consumption is the largest contributor and is increasing faster than any other energy sector. However, efforts to manage electricity show the slowest decline in emissions progress.
This country’s 130 million homes together generate more than 20% of the nation’s carbon dioxide greenhouse gas emissions. This is one of the most significant contributing sources in the country to global warming. Existing techniques and technologies in energy efficiency retrofitting can reduce home energy use by up to 40 percent per home on average which would also lower our national greenhouse gas emissions by 160 million metric tons annually by the year 2020. In addition doing so would reduce home energy bills by $21 billion a year and over time these savings would more than pay for the high up-front costs for energy efficiency retrofitting.
It appears that Google is getting ever deeper into the sun business. Stating that it is dissatisfied with the general lack of progress on achieving breakthroughs in green technology, the company wants to build better highly reflective and rugged mirrors — as well as the mirror substrate that the reflective surface is mounted on. By reflecting more light and more of the solar spectrum than ordinary mirrors these mirrors have the potential to reduce the cost of solar thermal systems by up to 25 per cent.
Last week, Sierra Magazine named the nation’s top 20 “coolest” schools for their efforts to stop global warming and operate sustainably. The magazine’s September/October cover story spotlights the schools that they believe are making a true impact for the planet, and marks Sierra’s third annual listing of America’s greenest universities and colleges. The […]
Green roofs, green walls, green parking lots, shade trees, the greening of urban spaces in general, the restoration of urban waterways, wetlands and the re-greening of brownfield areas; can all be thought of as different techniques to nurture a green living skin over regions of urban development. While there are many important differences between each of these separate techniques as well as their underlying technologies they all share a common overarching goal of bringing an analog of the natural living green skin that characterizes the natural landscape back into our urban areas. They all promote the restoration and re-integration of these heavily populated areas back into the surrounding natural environment.
Last week, at the National Clean Energy Summit 2.0 in Las Vegas, Energy Secretary Chu called for a revolution, “a second industrial revolution.” The first industrial revolution came with a “carbon dioxide cost” but “in the next industrial revolution, we must develop technologies that will enable us to get the energy the world needs to grow and prosper but “essentially reducing and eliminating the carbon dioxide,” he said. Chu said the United States has the greatest research and development centers in the world in universities, national labs and the private sector. “Once we get this great invention machine geared and going we’d be invincible. But the only trouble is, let’s get it going.”
