This December 2016 draft of U.S. GLOBAL CHANGE RESEARCH PROGRAM CLIMATE SCIENCE SPECIAL REPORT (CSSR) was written by top scientists, many of whom I know and respect, according to a congressional mandate initiated over 15 years ago. This is the fourth report, due every four years. It summarizes what we understand about climate change in the US (as opposed to the entire planet; there are important differences), but does include some info about relevant global processes like sea level and oceanic change.
A really important section is about how Arctic changes affect the US.
It was open for comment earlier this year, so I'm not sure what the big news story is, except that maybe some think it's official release as a government document is uncertain.
There is a fairly accessible executive summary at the front. I encourage you to take a look.
A draft report by scientists from 13 federal agencies, which has not yet been made public but was obtained by The New York Times, concludes that Americans are feeling the effects of climate change right now.
