Viewimage.jpg Lifestyle, technology and CO2 emissions in China Last Updated on 2014-06-28 17:59:40 Introduction China as the world’s largest developing country and the most populous country has achieved notable success in developing their economy with approximate 10 percent average annual growth of GDP over the last two decades [1-3]. Large sections of the population have been experiencing a transition from ‘poverty’ to ‘adequate food and clothing’; today growing parts of the population are getting closer to ‘well to do’ lifestyles [3]. However, the rapid growth of the economy has not only lead to dramatic changes of wealth and people’s lifestyle, but has also caused a huge amount of resources and energy consumption and associated CO2 and other emissions creating serious environmental problems on both local, regional and global scales [4-6]. Between 1990 and 2004 China’s total energy consumption has grown 5.0% annually from... More »
Video: Global Warming's Six Americas Last Updated on 2013-07-11 15:16:38 Anthony Leiserowitz, director of the Yale Project on Climate Change Communication, discusses the divergent views of Americans over climate change. This help to clear the idea of what actually people think about climate change and how can we involve people in this issue. Watch >> Global Warming's Six Americas Can be used in any classes where we talk about people and society on climate change. Simple questions can be asked on the topic to know the student understanding More »

Arctic Barrow-AK NOAA.jpg Carbon dioxide milestone in Arctic Last Updated on 2012-06-03 00:00:00 Carbon dioxide atmospheric concentrations at Barrow, Alaska, reached 400 parts per million this spring—the first time a monthly average measurement for the greenhouse gas attained the 400 ppm mark in a remote location. NOAA: Carbon dioxide levels reach milestone at Arctic sites NOAA cooperative measurements in remote, northern sites hit greenhouse gas milestone in April The concentration of carbon dioxide in the atmosphere of Barrow, Alaska, reached 400 parts per million (ppm) this spring, according to NOAA measurements, the first time a monthly average measurement for the greenhouse gas attained the 400 ppm mark in a remote location. Carbon dioxide (CO2), emitted by fossil fuel combustion and other human activities, is the most significant greenhouse gas contributing to climate change. “The northern sites in our monitoring network tell us what is...

Earth Climate Colorful 375px DOE.jpg Targeting other climate change gases Last Updated on 2011-08-04 00:00:00 NOAA study: Slowing climate change by targeting gases other than carbon dioxide The direct warming influence of all long-lived greenhouse gases in the atmosphere today attributable to human activities. CO2’s warming influence of 1.7 watts/m2 is equivalent to the heat from nearly 9 trillion 100-watt incandescent light bulbs placed across Earth’s surface. The combined influence of the non-CO2 greenhouse gases is equivalent to the heat from about 5 trillion bulbs. The category “other”includes a few very long-lived chemicals that can exert a climate influence for millennia. Download image here. (Credit: NOAA) Carbon dioxide remains the undisputed king of recent climate change, but other greenhouse gases measurably contribute to the problem. A new study, conducted by NOAA scientists and published online today in Nature, shows that cutting emissions... More »
