Climate change:
Climate change is caused mainly by increase of human activity and industrialisation. For example, activities such as driving cars, farming, burning coal and cutting down forests produce greenhouse gases – mainly carbon dioxide, methane and nitrous oxide which are emitted into the atmosphere, which create a layer of greenhouse gases around the earth and trap the sun 's heat.
The earth over its 4.5 billion-year history has naturally fluctuated from ice ages to extreme droughts, however in the last 10,000 years or so, the climate became much more stable and sustainable for human beings to live. However, in the past 50-100 years, particularly in the 21st century, with increased human activity like agriculture, transportation, etc, green houses gases have increased majorly and have caused extreme events such as increased floods, storms, cyclones, droughts and landslips. The weather is not only warming up but is also becoming much colder in areas in an extremely fast rate.

Climate change is occurring worldwide, as it is effecting the earth directly. However, these are areas on Earth that are already feeling the impact of climate change more than others. For example,
Satellite measurements have showed that the waters of Australia 's Great Barrier Reef have warmed by 0.2 degrees Celsius on average over the past 25 years which have led to a decline in the amount of seafloor covered in coral. A 2012 study published in the journal Proceedings of the National…
