NOAA data showed that October was the hottest October on record globally, with temperatures climbing more than one degree Fahrenheit above the 20th century average of 57.1 F.
__The record high October temperature was driven by warmth across the globe over both the land and ocean surfaces and was fairly evenly distributed between the Northern and Southern Hemispheres,__ the agency said.
Meanwhile, the average global temperature between January and October has been 0.68 degrees Celsius (1.22 degrees Fahrenheit) higher than the 20th century__s average global temperature of 14.1 C (57.4 F).
NOAA__s analysis breaks down global temperatures into two categories, land and sea, as well as an average that includes both. October__s record high temperatures were clocked across both land and sea.
The surface temperature on land approached a significant and potentially perilous scientific benchmark at almost 2 degrees Celsius higher than the 20th century average for October of 9.3 C (48.7 F).
Any temperature increase above the 2 degree Celsius mark is __dangerous,__ according to the non-binding international agreement on climate change, the Copenhagen Accord, reached in 2009.
Experts have long predicted that a change in global average temperature of just 2 to 3 degrees higher could have catastrophic consequences, contributing to disastrous storms, storm surges, melting polar ice and sea level rise.
October__s ocean temperatures were also the warmest on record, according to NOAA, with an increase of 1.12 F over the 20th century average of 60.6 degrees.
Of particular concern, several countries have already seen an average temperature increase exceeding 2 degrees Celsius in October 2014 compared to 20th century averages, including France, Germany, Switzerland, Sweden and Australia.
__Record warmth for the year-to-date was particularly notable across much of northern and western Europe, parts of Far East Russia, and large areas of the northeastern and western equatorial Pacific Ocean,__ NOAA said.
__It is also notable that record warmth was observed in at least some areas of every continent and major ocean basin around the world,__ the agency added.
The midsection of the United States, which saw a severe winter, was a notable exception, with its average temperature this year below the 20th century average.
