Global Climate Change

YAY, its Wednesday again! cool Today, we learnt about global climate change. Me and my group members feel very strongly for this topic, we should all do our part to reduce global warming and protect the environment (+ the polar bear cry) Anyway, these are our group’s answers for this week’s questions:

Question 1

Even though the amount of energy emitted is more than what it receives, the atmosphere still retains much of the emitted energy due to greenhouse gases. In addition, the Earth itself produces heat energy from its own core.

Question 2

The statement is incorrect. Global warming is causing the climate to be warmer and climate is described as the average weather over a long period of time (e.g. 20 to 30 years). However, winter is only a condition of the atmosphere that exists over a short period of time (i.e. one year). Hence, the fact that winter occurs does not mean global warming is not happening.

Question 3 

The rotation of water molecules in the atmosphere interferes with the detection of intended objects. Hence, it defeats the purpose of the radar.

Question 4 

The most serious short-term problem for us will be air quality. This is especially true as we live in cities where there are factories around the industrial area. This may lead to serious air pollution which will ultimately cause health problems such as breathing difficulties or lung diseases. In the long run, the most serious long-term concern is likely to be global warming as our lifestyles are likely going to be affected it, such as the need to reduce the wastage of electricity. In addition, other consequences of global warming include loss of sea ice, accelerated sea level rise and longer, more intense heat waves. These effects may lead to natural disasters such as tsunami eccentric weather patterns. Due to the rising sea levels, lands of lower altitude may be submerged, hence reducing the amount of available land for usage.

Yay, it has ended. Looking forward to recess week because our favourite lecturer has so kindly given us an extra week of break! WOOHOO!!! xD (Thank you prof laughing) bye!!!!!!!!
