The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years.1 Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate. The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response. Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels. They also show that in the past, large changes in climate have happened very quickly, geologically-speaking: in tens of years, not in millions or even thousands.3 thank for watching my prezi on global warming Global Warming Presentation How will Global Warming affect us, humans and plants around us? A) Global warming is affecting more than one species. Many of these species are closely related to us. Others, including plants and animals are also suffering from this huge impact of temperature rising of our earth and atmosphere. The main cause of global warming are HUMANS; we are the main cause of our own death! Evidence that proves that we are the main cause of global warming is the green house effect; the green house effect is when more and more fossil fuel gases are being administered into the air, such as methane and carbon dioxide. These fuels are causing the heat from this burning to stay near the earths surface, causing the heating of our planet. http://www.cnn.com/2007/TECH/science/02/02/climate.change.report/ We are polluting air and our water resources! Look at the graph below to find out exactly how much pollution we are really distributing into the air, and water. Graph of the Sources of Greenhouse Gases Climate change will have a significant impact on the sustainability of water supplies in the coming decades. A new analysis, performed by consulting firm Tetra Tech for the Natural Resources Defense Council (NRDC), examined the effects of global warming on water supply and demand in the contiguous United States. The study found that more than 1,100 counties -- one-third of all counties in the lower 48 -- will face higher risks of water shortages by mid-century as the result of global warming. More than 400 of these counties will face extremely high risks of water shortages.
