In this file of SCI 207 Week 4 Laboratory Questions you will find the next information: 1. Identify natural and human-made causes of climate change visible in the computer simulation. According to the computer model‚ how have sources of heat-trapping pollution changed from 1750 to today? How does the simulation predict they will change by 2050? 2. According to the computer model and your readings‚ which source of heat-trapping pollution‚ contribute the most to climate change? Explain

Greenhouse Gases: Carbon dioxide (CO2) is a greenhouse gas in the atmosphere that may raise average temperatures on Earth. The burning of fossil fuels could be responsible for the increased levels of carbon dioxide. If current trends continue‚ future concentrations of atmospheric carbon dioxide in parts per million (ppm) could reach the levels shown in the accompanying table. The CO2 concentration in the year 2000 was greater than it had been at any time in the previous 160‚000 years. Year 2000

INTRODUCTION [SLIDE 2] Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface‚ some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time‚ the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back

The greenhouse effect in is the entrapment of the sun’s heat energy in the earth’s atmosphere. Greenhouse gases such as carbon dioxide‚ water vapor‚ methane‚ and nitrous oxides are all gases that contribute to this phenomenon. Carbon dioxide is the most abundant greenhouse gas while water vapor the least harmful gas makes up less than one percent of the gases in the atmosphere. These greenhouse gases are produced naturally by the earth for example carbon dioxide‚ and methane is produced from the

CLICK TO DOWNLOAD SCI 207 Dependence of Man on the Environment Week 1 Biomes and Diversity. As you have learned in the readings‚ extinction is a natural selection process. You have also read that humans are often responsible for accelerating this process. Using at least two scholarly sources‚ address whether or not we as humans should be concerned with the extinction rate. Additionally‚ discuss whether or not humans strive to preserve representative samples of all biomes on the planet

wonder why disastrous weather events like super-storm Sandy continue to increase in their frequency and severity? Many modern scientists attribute these dangerous environmental trends of global warming to the ‘greenhouse effect’. The ‘greenhouse effect’ results from greenhouse gases such as carbon dioxide rising into the atmosphere‚ trapping infrared radiation from the sun‚ and emitting ultraviolet radiation that can puncture the earth’s stratospheric ozone layer. A healthy ozone layer should

Well‚ based on my research‚ wind energy is the result of the sun’s energy interacting with the earth’s surfaces. It is also an ideal renewable energy source that is infinitely sustainable; pollution free; doesn’t use fuel; and doesn’t produce greenhouse gases‚ toxic or radioactive waste. This type of energy is considered a green power technology because it has minor impacts on the environment. When using wind to generate electricity we use machines known as turbines and this turbines use blades that
