The CIA

Established in 1947, the Central Intelligence Agency (CIA) is an independent executive bureau of the US government. Its primary function is obtaining and analyzing information about foreign governments, corporations, and persons, and reporting such information to the various branches of government. Congress placed restraints on its activities in the early 1970s, when reports that it had engaged in assassinations and domestic spying surfaced. When were many of these restraints removed?

Cooling Sun Not Heating Up Earth

New research from scientists in Britain and Switzerland challenges the theory that global warming is a natural phenomenon caused by solar radiation. The report indicates that since the mid-1980s, solar activity has been decreasing. Thus, the sun's impact on the global climate should have been a cooling one. Despite this trend, average global temperatures have continued to rise. As such, scientific consensus overwhelmingly points to human activity as the cause for this planetary warming.
