Ecosystems - refers to the combined physical and biological components of an environment. Global warming and the Greenhouse Effect- (The hows, whys, and impact on the future.) Global Warming - is a recent warming of the Earth's surface and lower atmosphere, it is believed to be the result of a strengthening of the greenhouse effect mostly due to human-produced increases in atmospheric greenhouse gases. Greenhouse Effect - The greenhouse effect is a process by which radiative energy leaving a planetary surface is absorbed by some atmospheric gases, called greenhouse gases. They transfer this energy to other components of the atmosphere, and it is re- radiated in all directions, including back down towards the surface. This transfers energy to the surface and lower atmosphere, so the temperature there is higher than it would be if direct heating by solar radiation were the only warming mechanism

Future impacts could be melting of the polar ice caps, destruction of coral reefs, severe winters and summers, excessive rain fall in some areas and not enough in others, drought etc. What topic regarding greenhouse effect do scientists argue about? They argue about the actual heating of the earth, is CO2 a greenhouse gas, and if there are heat flares in the ozone layer. The different greenhouse gasses (Carbon monoxide vs dioxide and what they do) Carbon monoxide (CO) is only a very weak direct greenhouse gas, but has important indirect effects on global warming. Carbon monoxide reacts with hydroxyl (OH) radicals in the atmosphere, reducing their abundance. As OH radicals help to reduce the lifetimes of strong greenhouse gases, like methane, carbon monoxide indirectly increases the global warming potential of these gases. Carbon dioxide ( ) is one of the greenhouse gases. The absorption-emission- absorption cycle of CO2 serves to keep the heat near the surface, effectively insulating the surface from the cold of space. Large amounts of CO2 in the atmosphere trap more heat causing the recent effects of global warming. Carbon dioxide and how it impacts the environment. Carbon Dioxide (CO2) is a colorless, odorless non-flammable gas and is the most prominent Greenhouse gas in Earth's atmosphere. It is recycled through the atmosphere by the process photosynthesis, which makes human life possible. Antarctica and carbon dioxide findings. As the CO2 gases continue to rise it is causing a mass heating effect which is melting Antarctica’s Ice Cap. At the current rate of global warming the entire ice cap will be melted in the next few decades. The person who started the phrase: “Greenhouse Effect” Fourier if that one isn’t there pick Pouillet The effect industrialization initially has on birth and death rates (a VERY confusing set of answers...read carefully) Decrease in death and decrease in birth rates.
