the debate has heated up on the controversy of global warming. Politicians have even used the issue to boost their campaigns. Some question whether the earth’s temperature is rising at an unusual rate. Scientists perform experiments from glacial ice to observe the correlation between carbon dioxide levels and temperature. Scientists have changed the debate over the years from debating whether global warming was actually happening to the current debate about what is causing global warming. Therefore
years ago they didn’t burn hydrocarbons like we do now, and the temperatures then were warmer than they are now. 200 - 500 years ago the earth went through a cooling period known as a “Little Ice Age” (Robinson, Robinson, & Soon, 2008). We are currently recovering from that cooling period. During the Little Ice Age temperatures dropped well below average. However, a study of more recent history temperatures can also show that the climates are cyclic and not the result of human activities.
specifically altered our climate. Scientists have described our world as a clump of matter that spun out of the sun to join its journey hurling though cold and empty space. Our spaceship earth would match the moon and have no climate had not molten core continued to pierce its cold crust, spewing forth chemicals that would eventually form our atmosphere, our seas and life itself (“Mcphee”). The geological record shows a tumultuous earth, but because the events occur slowly over millions of
explanation and history The scientific discovery of climate change began in the early 19th century, when ice ages and other natural changes were first suspected. It was also around the same time when natural greenhouse effects were first identified. John Mercer was a glaciologist following the work of John T. Hollin (1962) suggesting that climatic warming and rising sea levels are causing the Antarctic ice shelves to retreat. This discovery is one of the major discoveries that contributed to the publication
is that the evidence and the effects on species all over the world are real, and earth and its systems and creatures account for one hundred percent of our resources, directly or indirectly. The health of our planet is our responsibility, and this report examines the ramifications of human life and a closer look at Coral reefs, a key ecosystem facing the heat. The Controversy over Anthropogenic Climate Change When examining climate change, it’s important to understand human’s roles. This includes
