Climate Change and Global Warming Essay

CauseClimatologists, who predict short and long-term mood trends, believe carbon copy dioxide and other emissions, mainly from industrial and commercial military action over the last two centuries, hurt altered the primings standard pressure. This change has caused a babys room effect which is rapidly potenting the planet. makeThe predicted effects of worldwide thawing include the melting of polar methamphetamine caps a significant rise in sea levels more perfect weather events a reduction in agricultural land piddle shortages food shortages loss of rain forests and more species becoming extinct.SolutionsScientists believe every nations must take immediate and urgent action to dramatically reduce carbon emissions. Technological solutions view been proposed, ranging from carbon scrubbers that remove carbon from the atmosp present and reduce greenhouse fuck upes to placing giant mirrors in space to contrive fair to middling cheer to cool down the planet.ControversyAl though an overwhelming majority of scientists ingest the man-made global warming theory, a minority deal questi unitaryd this consensus. They propose that mans impact on the climate is negligible and that global warming is wholly the result of natural cycles.David Kennedy, nd.

The greenhouse effect is when sunlight escaping back into space is absorbed by gases in the atmosphere and wherefore reflected back onto the Earths surface. Most greenhouse gas is pee vapor, but other gases that contribute to it include carbon dioxide, methane, ozone, and other gases that have a less significant impact.Carbon DioxideAccording to the U.S. Emissions Inventory 2004 executive Summary, in 2002 around 40 percent of carbon dioxide e missions were the result of impatient coal for electricity. Around 93 percent of the electric utility pains burns coal. Carbon dioxide emissions in any case come from cars and other vehicles, airplanes and buildings. New technologies, same the hydrogen fuel cell vehicle and hybrid electric vehicles, argon some solutions for minimizing vehicle carbon dioxide emissions.MethaneMethane is the second largest contributor to the greenhouse effect. Methane is a natural byproduct of living organisms and is produced by plants and bovine flatulence. Bacteria decomposing native material also produce methane. According to the U.S. Emissions Inventory 2004 Executive Summary, methane levels have increased by 145 percent in the last hundred years. In the United States, all rice fields are fully grown in flooded areas which produce methane gases.DeforestationDeforestation is the process of glade forests, either rainforest or temperate forests. The burning of forests is responsible for up to 25 percent of carbon dioxide emissions. This is the result of clearing and cutting virtually 34 million acres a year. Forests are also substantial because they convert carbon dioxide into oxygen. So while carbon dioxide emissions increase, the lack of forests is reservation the number increase faster.PermafrostPermafrost is a layer of land and soil that has been frosty and kept at freezing temperatures or below. In many northern climates like Alaska, Canada and Siberia, the permafrost layer of soil holds vast amounts of carbon. What researchers and scientists fear is that the permafrost go forth warm up and microbes will decompose the soil and release carbon dioxide. Permafrost has absorbed carbon dioxide for thousands of years, but may release it back if thawed.Timothy Sexton,.nd. Global Warming Cause & effects retrieved February 27, 2013 from http//www.ehow.com/about_4744736_global-warming-cause-effects.html Global Warming Cause & EffectsGreenhouse EffectThe overriding caus e of global warming is an umbrella term known as the greenhouse effect. As the rays of the sun tally Earth, some of the heat is absorbed and some is radiated back into the atmosphere. Greenhouse gases in the atmosphere act similarly to a gigantic mirror and reflect warmth back to Earth that in the past would have keep being radiated into space. It is this reflection of heat back to Earth that is at the touchwood of the greenhouse effect.Greenhouse GasesThese greenhouse gases that are responsible for reflecting back heat that would otherwise be lost include simple water supply vapor, carbon dioxide, methane and the infamous ozone. Unfortunately, there is no way to know exactly which greenhouse gas is most responsible for the greenhouse effect.Cause of Increased GasesThe business of global warming has been caused by the admittance of more greenhouse gas into the atmosphere. The gases responsible will rise into the air whether humans are here or not the problem is that much of ba sic human practise in the 20th and 21st century produced greenhouse gas at a level never experienced before. Basically, any activity that produces one of the gases listed above is a cause of global warming everything from driving a car to using electricity. Because trees act as a natural vicissitude plant to transform carbon dioxide into oxygen, deforestation contributes to global warming because the few trees there are, the more carbon dioxide gets into the atmosphere.EffectsThe effects of global warming are potentially far-ranging. Increased temperatures means melting of glaciers, ice and deoxycytidine monophosphate around the poles, which means an increase in sea levels. Warming water will also increase the potential for hurricanes and typhoons so devastating that they will make Hurricane Katrina pale in comparison. That rise in sea levels could also mean that beachfront property will soon be found 10 to 50 miles inland from where beaches are now.TemperaturesThe average tempe rature on Earth has been steady rising since the mid-1980s, and global warming is expected to continue this trend. In addition to longer and hotter summers, rising temperatures will affect agriculture. Indeed, the effect of a hotter Earth is already increasing the transmission of infectious bacteria that thrive beneath warm conditions.Hoax?There are still a spectacular many people who believe that global warming is simply some kind of politically-created hoax. Those leading the charge against global warming tend to be industry with a vested interest. On the other hand, the list of scientific entities that have agreed on the reality of global warming include, among many others, the depicted object Oceanic and Atmospheric Administration, the Environmental Protection Agency and the Royal beau monde of the UK.
