ground information, or reiteration of a premise or the conclusion.

[1] Is global warming a real threat? [2] Or is it hype propagated by
tree-hugging, daft environmentalists? [3] President George W. Bush
apparently thinks that the idea of global climate change is bunk. [4]
But recently his own administration gave the lie to his bunk theory. [5]
His own administration issued a report on global warming called the
U. S. Climate Action Report 2002. [6] It gave no support to the idea that
global warming doesn’t happen and we should all go back to sleep. [7]
Instead, it asserted that global warming was definitely real and that it
could have catastrophic consequences if ignored. [8] For example,
global climate change could cause heat waves, extreme weather, and
water shortages right here in the United States. [9] The report is also
backed by many other reports, including a very influential one from
the United Nations. [10] Yes, George, global warming is real. [11] It
is as real as typhoons and ice storms.
