19th century to present day, the effects that humans have on the earth’s climate have been studied. Scientists have been able to track the earth’s climate change through out history. In the 1930s a noticeable warming trend was noticed compared to the average temperature in the 19th century. Guy Stewart Callendar, an English engineer, studied the changes in the climate and concluded that the human emissions of carbon dioxide gas could lead to the “greenhouse effect”. “With a new awareness that climate

Climate Change: Global Warming In April 9th of 2010, Marisa Marcavillaca—a farmer and indigenous women’s organizer from Peru— went to The Capitol Hill to tell her powerful story. Her words were quoted by Al Gore in one of his speeches. She said through a translator: “We are very concerned, in my community, [and] in my country, about global climate change. Nature is disrupted. We are seeing the impacts on a daily basis. We are losing our lands, water is disappearing, it rains when it shouldn’t

Causes of global warming For a long time people on our Earth didn't think a lot about greenhouse gases. The situation changed when people started using more and more energy in the form of fossil fuels, like oil, gas and coal. We burn fossil fuels to power factories, run cars, produce electricity and heat houses. As fossil fuels burn they let carbon dioxide into the atmosphere. During the last few decades people have also cut down many forests. Trees use carbon dioxide when they make their own food

human rights, health and environmental protection have expanded considerably in the past several decades. In response, the international community has created a vast array of international legal instruments, specialized organs, and agencies at the global and regional levels to respond to identified problems in each of the three areas. Often these have seemed to develop in isolation from one another. Yet the links between human rights, health and environmental protection were apparent at least from

documentary on global warming entitled “An Inconvenient Truth” . The movie earned several awards including an academy award for best documentary and gore later received a noble peace prize. The movie discussed several different topics of great concern to global warming; such as permafrost, climbs in temperature, extinction of species, drought, and fatigue to name a few. Four writers in five different articles discussed the three topics of greenhouse gases, climate change, and causes of global warming. These

The Effects of Alternative & Renewable Energy The Effects of Alternative & Renewable Energy The United States has massive dependency fossil fuels. Based on the US Department of Energy 2010 information, an incredible eighty five percent of the U.S total energy needs are directly related to the use of fossil fuels and seventy percent used for transportation needs. As stated by Lefton, R. & Weiss, D.J. the U.S accounts for three percent of the world’s population, however the U.S gulps

Week 5 Global Warming C02 and You Bonita Jones-Bey 1. Is your emission higher than average US emission? By how much. See report 2. What steps will you be taking to reduce your emission? We currently use one vehicle more than the other one. The one with the better ass mileage of 38 mpg. 3. What needs to be done to increase sinks and reduce sources? Change in Uses of Land Increasing carbon storage by using land differently or maintaining carbon storage by avoiding land degradation. • Encouraging
