The climate is changing due to global warming. The earth is warming up. With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are diminishing. The main characteristics of climate change are global warming; changes in cloud cover and precipitation particularly over land; melting of ice caps and glaciers and ...view middle of the document...
Even if countries reduce their greenhouse gas emissions, the Earth will continue to warm. Predictions by 2100 range from a minimum of 1.8Â°C to as much as 4Â°C rise in global average temperatures. Human beings have been adapting to the variable climate around them for centuries. Worldwide local climate variability can influence peoplesâ€™ decisions with consequences for their social, economic, political and personal conditions, and effects on their lives and livelihoods. The effects of climate change imply that the local climate variability that people have previously experienced and have adapted to changing and changing at relatively great speed.
Key words: green house gases, methane, precipitation, warming, climate variability.

The climate is changing. The earth is warming up. With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are diminishing. Many are agreed that climate change may be one of the greatest threats facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities in weather patterns. Global warming and climate change refer to an increase in average global temperatures. Natural events and human activities are believed to be contributing to an increase in average global temperatures. This is caused primarily by increases in â€œgreenhouseâ€ gases such as Carbon Dioxide (CO2). The National Oceanic and Atmospheric Administration (NOAA) explained there are seven indicators that would be expected to increase in warming world and three indicators would be expected to decrease as shown in figure 1 with upward and downward arrows.
What is the Greenhouse Effect?
The term greenhouse is used in conjunction with the phenomenon known as the greenhouse effect.
â€¢ Energy from the sun drives the earthâ€™s weather and climate, and heats the earthâ€™s surface;
â€¢ In turn, the earth radiates energy back into space;
â€¢ Some atmospheric gases (water vapor, carbon dioxide, and other gases) trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse;
â€¢ These gases are therefore known as greenhouse gases;
â€¢ The greenhouse effect is the rise in temperature on Earth as certain gases in the atmosphere trap energy.
Six main greenhouse gases are carbon dioxide (CO2), methane (CH4) (which is 20 times as potent a greenhouse gas as carbon dioxide) and nitrous oxide (N2O), plus three fluorinated industrial gases: hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). Water vapor is also considered a greenhouse gas.

The Greenhouse effect is natural. What do we have to do with it?
Many of these greenhouse gases are actually life-enabling, for without them, heat would escape back into space and the Earthâ€™s...
