Industrial processes, energy production from burning fossil fuels and deforestation have been the major contributors to this observed trend in global warming. Even though the overall trend is of global nature, the sources of GHG emissions across the globe have varied drastically between regions and individual countries. A new study by Concordia University’s H Damon Matthews et al. published in Environmental Research Letters last week represents a sound estimate of what countries have historically been the largest GHG emitters and contributors to global warming. The calculations performed in the include an from five different emissions:<br />Fossil Fuel CO2<br />Land-use CO2<br />Methane<br />Nitrous Oxide, and<br />Aerosols, which have a cooling effect on the climate.<br />The results of the study show that the United States is the clear leader is both GHG emissions and contributions to global warming. Of the 0.7 C increase in global temperature since pre-industrial times, the United States alone has contributed 0.15 C (~20%). The top seven contributors alone account for ~63% of warming contributions, and the top 20 countries account for ~82%. China, which is presently the largest global emitter of GHGs, ranks 2nd on historical contributions to global warming, followed by Russia and Brazil and India. Brazil and India are interesting cases given that most of its CO2 emissions have originated from land-use emissions, meaning that deforestation has contributed to Brazil’s high ranking. This is different from the other top GHG emitting countries, whose main CO2 emissions can be tied back to the burning of fossil fuels. The study also includes the cooling effects that aerosol emissions have on the global climate. Generally, countries that emit larger quantities of CO2 also produce larger amounts of aerosols, which help counteract the warming effects of the CO2 emissions.Riaz Haqhttps://www.blogger.com/profile/00522781692886598586noreply@blogger.comtag:blogger.com,1999:blog-8278279504304651957.post-26926979496612567432016-04-23T09:40:07.784-07:002016-04-23T09:40:07.784-07:00BBC News - BBC Pop Up: A lack of #water and #wives...BBC News - BBC Pop Up: A lack of #water and #wives in #India. #Drought #FemaleGenocide #Women<br /><br />http://www.bbc.com/news/world-asia-india-36104869<br /><br />"Who would give their daughter to this village?"
