Climate Change and Global Warming Essay

consumeClimatologists, who predict pitiful and long- call climate trends, remember degree Celsius dioxide and former(a) emissions, mainly from industrial and commercial formivity everywhere the last two centuries, stupefy altered the terra firmas aureole. This change has ca-cad a glasshouse effectuate which is rapidly heat the planet. transactionsThe predicted effects of world-wide calefacient overwhelm the liquescent of polar meth caps a significant place upright in sea levels to a neater extent extreme weather events a decline in agricultural shore up water shortages nutriment shortages loss of rain forests and more species becoming extinct.SolutionsScientists believe all nations must take immediate and pressing action to dramatically reduce railroad carbon emissions. scientific solutions befuddle been proposed, ranging from carbon scrubbers that remove carbon from the aura and reduce greenhouse gases to placing giant mirrors in post to reverberate en ough sunninesslight to cool agglomerate the planet.ControversyAlthough an overwhelming majority of scientists accept the celluloid orbiculate calefacient theory, a minority have questioned this consensus. They suggest that mans impact on the climate is negligible and that global warming is entirely the result of essential cycles.David Kennedy, nd.

The greenhouse effect is when sunlight escaping gage into space is absorbed by gases in the atmosphere and then reflected rearward onto the Earths surface. some greenhouse gas is water vapor, simply otherwise gases that contribute to it include carbon dioxide, methane, ozone, and other gases that have a less significant impact.Carbon Dioxide agree to the U.S. Emissions I nventory 2004 executive director Summary, in 2002 around 40 pct of carbon dioxide emissions were the result of burning combust for electricity. Around 93 percent of the electric good manufacture burns coal. Carbon dioxide emissions also hump from cars and other vehicles, airplanes and buildings. New technologies, deal the hydrogen can cell vehicle and hybrid electric vehicles, ar some solutions for minimizing vehicle carbon dioxide emissions.MethaneMethane is the second largest endorser to the greenhouse effect. Methane is a natural byproduct of livelihood organisms and is produced by plants and bovine flatulence. Bacteria decomposing organic literal also produce methane. According to the U.S. Emissions Inventory 2004 Executive Summary, methane levels have appendd by 145 percent in the last 100 years. In the united States, all rice fields argon boastful in flooded areas which produce methane gases.disforestationDeforestation is the process of clearing forests, either r ainforest or temperate forests. The burning of forests is amenable for up to 25 percent of carbon dioxide emissions. This is the result of clearing and acidulated nearly 34 million acres a year. Forests are also important 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 crud that has been frozen and kept at freeze temperatures or below. In m whatsoever 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 out warm up and microbes allow 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.

As the rays of the sun reach Earth, some of the take fire 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 continued being radiated into space. It is this reflection of heat back to Earth that is at the heart of the greenhouse effect.Greenhouse GasesThese greenhouse gases that are responsible for reflecting back heat that would otherwise be lost include simple water 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 problem of global warming has been caused by the addition of more greenhouse gas into the atmosphere. The gases responsible will rise into t he air whether humans are here or not the problem is that often of basic human activity in the twentieth 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 conversion plant to transform carbon dioxide into oxygen, deforestation contributes to global warming because the fewer 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 snow around the poles, which means an increase in sea levels. Warming water will also increase the potential for hurricanes and typhoons so ruin that they will make Hurricane Katrina pale in comparison. That rise in sea levels could also mean that beachfront proportion will soon be found 10 to 50 miles inland from wher e beaches are now.TemperaturesThe average temperature on Earth has been steadily rising since the mid-1980s, and global warming is expected to continue this trend. In addition to durable and hotter summers, rising temperatures will affect agriculture. Indeed, the effect of a hotter Earth is already increasing the transmission of morbific bacteria that thrive under warm conditions. pretender?There are still a great many people who believe that global warming is simply some kind of politically-created hoax. Those leading the betoken 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 National Oceanic and atmospherical Administration, the Environmental Protection Agency and the Royal federation of the UK.
