Federal report says humans are the cause of climate change
Today, over a dozen federal agencies released the Climate Science Special Report, which is a product of the National Climate Assessment -- a congressionally mandated review that takes place every four years. In it, hundreds of scientists from dozens of government agencies and academic institutions present evidence that supports the existence of a human-caused warming planet and all of the consequences that come with it. "This assessment concludes, based on extensive evidence, that it is extremely likely that human activities, especially emissions of greenhouse gases, are the dominant cause of the observed warming since the mid-20th century," the report stated. "For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence."
