Main point: What is Climate Change?

According to the Australian Academy of Science, Climate change is define as a change in the statistical properties of the climate system that persists for several decades or longer—usually at least 30 years.

The weather that we have or may have is a reflection of our atmosphere and the atmosphere is influenced by the oceans, land surfaces and ice sheets. Together they form the climate system. How we treat this group is going to be the outcome in our weather.

Transition: Now that you know what Climate Change is, I will tell you what causes it.

a) Temperatures will continue to raise, all the habitants on Earth are experimenting this changes around the world.

b) Changes in precipitations patterns

c) Heat waves and droughts

d) Hurricanes will be more intense although we are seeing this now; scientific predict it will be devastating in the future; causing losses on crops and an increase of diseases.

e) Sea level will rise from 1-4 feet by 2100 causing many people to migrate, although this is happening in many places in India.

f) Artic likely to become ice free because the heat trapped is already melting ice in Greenland, and scientists said it will continue if nobody takes action now.

We are all interconnected, and what you do to the environment, ultimately you do to yourself.” – Ian
