The drought gripping the nation has intensified in the Dakotas, Nebraska and Iowa where - combined - 38 percent of the country’s corn is grown. The root cause of increasing temperatures remains a bone of contention for the Trump Administration, and the official definition is a bit of a moving target.

Paul Yeager explains.

The United States may already be feeling the impact of climate change according to a report drafted by scientists from 13 government agencies.

The New York Times obtained a copy of the document in which some scientists felt compelled to call out huge differences in past research and current administration beliefs. At least one scientist said directly the Trump administration will try to suppress the research. However, at least four of the scientists interviewed said they don’t have specific examples to support the claim.

The report says extreme heat waves have become more common and extreme cold spells less common since the 1980s. The leaked documents reveal that - in the lower 48 - the annual average temperature has already climbed 1.18 degrees warmer over the last 30 years. Also stated was that the heating trend would continue if carbon pollution stays at current levels - translating into a 4.83 degree increase by mid-century.

Even how climate change is referred to is getting a makeover as a series of emails obtained from inside the USDA’s Natural Resources Conservation Service reveals a change in language from “climate change” to “weather extremes.”

The exact cause of the rise in temperature is part of an on-going debate as the president denies emissions of greenhouse gases are the basis of the increases claiming global warming is a hoax. The president has touted reviving America’s struggling coal mines and new oil pipelines as ways to bring jobs back to America. Federal scientists counter that burning those fossil fuels are driving the run-up in temperatures.
