NYPD statistics show that major crimes in January 2012 increased by 5.7 percent as compared to January 2011. In northern Manhattan, the numbers are even higher — an 11 percent jump.

NYPD officials believe the unseasonably warm temperatures are to be blamed for for the uptick in criminal activity — including robberies, burglaries and grand larcenies, according to a DNA Info report.

“That is the only factor that seems to have changed. Last winter the city was buried in snow, and now there has been barely a snow flake,” one official told the website.

While colder weather have moved into the area the last couple of days, Monday and Tuesday saw temperatures at or above 50 degrees.

A slight increase in crimes last year, broke a 20-year string of declines.
