The Presentation of Globe Warming (Part 2)

Let take a look at the pie chart.(Pie chart)

(The increase in the man-made emission of greenhouse gases is the cause

for global warming.)Besides that, Carbon dioxide emissions in million tons

per year over the last 200 years.Now I’d like you to take a look at this

graph. which shows how the increase of carbon dioxide between 1960-2006

Let me quickly explain the graph, this graph is about the increase of carbon

dioxide from 1960-2006. I’d like to focus your attention on the figure

between 1975-2006. ( Concentration of carbon dioxide has dramatically

increased in the last 50 years, in particular, the contribution pick up to

380 million tons at the year of 2006 )

There are two major effects of global warming:

Increase of temperature on the earth by about 3° to 5° C (5.4° to 9° Fahrenheit)

by the year 2100.

Rise of sea levels by at least 25 meters (82 feet) by the year 21

what can we do to prevent globe warming?
