... different regions. A warmed world is expected to have more extreme weather, with more rain during wet periods, longer droughts, and more powerful storms. Although the effects of future climate change are unknown, some predict that exaggerated weather conditions may translate into better agricultural yields in areas such ... may lead to severe drought and plunging agricultural yields in parts of Africa, for example. Warmer temperatures are expected to partially melt the polar ice caps, leading to a projected sea level rise of twenty inches by the year 2050. A sea level rise of this magnitu...

... Earth could not be sustained without the natural greenhouse effect. Weather stations, balloons, ocean buoys, and satellites tell us the Earth's temperature today. Ice cores, sediment layers, and tree rings tell us about what the Earth's climate has been like in the past. With this evidence, scientists ... next one hundred years. This may not sound like much, but it could change the Earth's climate as never before. At the peak of the last ice age (18,000 years ago), the temperature was only 7 ∘F colder than it is today, and glaciers covered much of North America! Even a ... the sam...

... Artic Ocean which will not only devastate arctic ecosystems, but will further climate change and weather. A warming of this extent could also begin an irreversible disintegration of the West Antarctic ice sheets which would result, within a few hundred years, in a further rise in sea level by at least 6 meters. The following greenhouse gases contribute to global warming at different degrees ... mean near the equator. Global warming could raise sea level one meter or more in the next century by expanding ocean water, melting mountain glaciers, and perhaps eventually causing polar ice shee...

... in our earth's landscape, in the 20th Century alone. Mean sea levels have increased by two millimeters annually, putting many low-lying nations in increasing danger during tropical storms. The incidence of tropical storms and other extreme weather events have dramatically increased. Temperature and precipitation shifts have forced many plants and animals to adjust their ranges upward in elevation and towards their ... respective poles. (Cunningham, 2000) Glaciers have been retreating at an alarming rate, and lake ice covers in the higher latitudes of the Northern Hemisphere last fourtee...

... increase the price of the gas about only 24 cents per gallon. This statistic shows how lackadaisical the government aims to reduce this gasoline consumption. Melting of glaciers and polar ice is one of the major effects of the global warming and it is deadly to humanity. According to state officials, reporter Timothy Wheeler stated, " [Maryland] has 450 facilities and ... warming is uncontrollable, but man-made causes are easily controllable by going, "green". Earth has been hotter ever before and places see heavy rain. These changes bring more storms that cost governments about a trill...
