More all-time global heat records bit the dust this winter than were initially suspected, according to a new and shocking National Oceanic and Atmospheric Administration (NOAA) report released Thursday.

Due to a combination of human-caused global warming and a powerful El Niño event in the Pacific Ocean, the month of February ranked as the most unusually warm month in the 137-year period of record, with global average surface temperatures running at 1.21 degrees Celsius, or 2.18 degrees Fahrenheit, above the 20th century average.
