The Asian carp captured this summer near the southern tip of Lake Michigan -- triggering a big scare -- apparently slipped past electric barriers.

Officials announced Friday that an autopsy of the 4-year-old fish showed that it originated in the Illinois/Middle Mississippi watershed, spending about a year in the Des Plaines River area.

This spring's heavy rain in the Lake Ontario region had quite an impact on homeowners, but it also affected the water offshore. The rainfall overwhelmed sewage systems in cities around the lake, and pushed tens of millions of gallons of raw sewage into the water.


The year 2016 was the warmest on record for the planet as a whole, surpassing temperature records that date back 137 years, according to an annual report compiled by scientists around the globe.
