Climate changes

Climate doesn’t equal to temperature. The change of several temperatures will only affect a small area, but climate changes will beget many serious problems on our earth.

 There are some reasons to cause climate changes, but the origin is targeted to human activities. Scientists have approved that: “If there were more carbon dioxide, the surface would warm.” (P63) Forming Carbon dioxide by the factories which produce their products through burning fossil fuels makes our atmosphere became unstable to increase the probability of extreme weathers happening and results global warming.

“In the context of climate variation, anthropogenic factors are human activities which affect the climate. The scientific consensus on climate change is "that climate is changing and that these changes are in large part caused by human activities," and it "is largely irreversible ” （http://en.wikipedia.org/wiki/Climate_change）

       However, the fact that climate changes hasn’t been mentioned frequently. There is part of a conversation by White House “science deniers”.

“Absolutely, let’s listen to scientists, absolutely, let’s work with job creators,” Jindal said. “But let’s not do so in a way that hurts our economy.” Asked about his personal views on climate change, he said he believed that the climate is “always changing.”

He didn’t answer the question straightforwardly, and paid the attention to economy instead of scientific conclusion.

Companies and government might hide it in order to keep their benefits. “Despite the attempts of the American oil and coal industry to obfuscate the scientific fact, people are waking up.” (73)
