Climate change is a familiar topic to us for decades. There is little doubt     1     Earth is getting warmer and warmer. A lot of evidence     2     (indicate) a dramatic change in the global climate.

The increase in temperature has     3     impact on Earth’s ecology. In 2013, a news photo of a dead polar bear which     4     (find) on Norway’s Arctic island of Svalbard made a lot of people     5     (shock). In addition, there is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide,     6     (cause) great loss of life and property. Climate scientists have warned that this warming trend will probably continue and there will be a     7     (high) price to pay, if we do not take appropriate actions.

“Greenhouse effect” is a key factor in clime change. Continued greenhouse gas emissions will result     8     further warming and long-lasting changes to the global climate. Governments should make     9     (policy) and take appropriate actions and measures. Individuals can reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce. It is our responsibility to seize every opportunity     10     (educate) everyone about global warming.
