Climate Change - 2015 global temperatures

The US National Oceanic and Atmospheric Administration (NOAA) has released a chart that illustrates how warm 2015 is, compared to the six other warmest years on record. 

2015 is running away with the title of 'warmest year'. 

The reason is a combination of global warming, and a strong El Nino event in the Pacific Ocean.



NOAA also released a comparison to all the years back to 1880, which is when the modern temperature record began.



It's also useful to look at years one by one in another way, colour-coded for El Nino, La Nina and 'neutral' years:




Every La Nina year since 1998 was warmer than every El Nino year before 1995.

Note that 2015 has not yet been added to that chart.
