... the Earth back to the Earth. Because of this, the Earth can be warmed up. As shown in Fig. 1, the sun releases many short waves which go into the Earth to warm it up. The Earth also emits heat waves, but these ones are long. The greenhouse effect is caused by pollution, which thickens the atmosphere and so blocks some of the long ... waves from escaping. Normally, most of these long waves leave the Earth and zoom into space. However, this thick atmosphere makes the waves bounces back to the Earth and so heats the ... a huge factor in the health of humans and other animals, especially t...

... Until human populations soared and began burning fossil fuels, greenhouse gases remained in relative balance. This affected climates to produce ice ages and heat waves that were the result of natural variation caused by sudden fluctuations in the sun's emission of radiation, volcanic eruptions and other affects.

... weather patterns, which in turn, cause harmful effects on forest trees. Climate warming can also lead to increased strength and occurrence of extreme weather conditions such as heavy precipitation and heat waves (IPCC, 2013). The boundary waters are considered a high risk zone for flooding due to the numerous amounts of lakes in the area. Heavy precipitation could cause a rise in the ... in water level would eventually lead to flooding. If the initial flood did not kill the trees, it would dramatically loosen the soil causing support issues for the gigantic trees. Heat waves could also ...

... are talking about, one would have to know why the earth is warming and what exactly is causing it. Greenhouse gasses are what is causing the earth to retain more heat. Greenhouse gasses "that have increased over the industrial period are carbon dioxide (CO2), methane (CH4), nitrous oxide (N20), and chlorofluorocarbons CFC-11." (2-453) The increase in these gases has caused ... (CO2), and ozone (O3), naturally present in the Earth's atmosphere, absorb thermal IR radiation emitted by the Earth's surface and atmosphere".

Global warming is the result of humans releasing heat-trapping gases into our atmosphere to power our modern lives. These gases are called green-house gases, which levels are the highest in the past 650,000 years. This causes ... the Earth to get warmer and warmer, because the gases trap heat.
