NOAA declares 2016 hottest year on record
The National Oceanic and Atmospheric Administration declares 2016 as the hottest year on record.
The 27th annual State of the Climate Report confirmed global temperatures increased around 1 degree Fahrenheit last year. 2015 originally held the record, and for the third consecutive year, national temperatures have reached record highs.
The NOAA say high greenhouse gas emissions and a strong El Nino are some factors for the high temperatures.
Meteorologist Mike Petrucelli at the National Weather Service in Medford say the extreme heat in the past weeks could be linked to warming, but it is too common of a local phenomena to tell.
"Some areas might be cooler than normal, some areas might have more extreme heating. So one event wouldn't be a contributing factor to the overall global warming for that calendar year," Petrucelli says.
Petrucelli says local warming during 2016 was a little higher, but not on the extreme levels.
