Slides from the NOAA/NASA Annual Global Analysis for 2018
The NASA author is Gavin A. Schmidt, and the NOAA author is Derek Arendt.
I have put photos of the graphs from the above analysis on a Flickr album NOAA/NASA Annual Global Analysis For 2018 so that they can easily be placed into talks. I have also added six photos from the NOAA State of the Climate 2018.
Here are some warming data from the NOAA Global Climate Report 2018.
For the global sea level temperature, 2018 is the fourth warmest year of the 139 year record from 1880-2018. 2016 was the highest, 2015 second, and 2013 third. 9 of the 10 warmest years occurred since 2005. 11 of the 12 months in 2018 were among the 5 warmest. The 2018 average temperature was 1.42ºF or 0.79ºC above the 20th century average. The notorious 1998 upward fluctuation due to an El Niño, is now only the 9th warmest year.
Since 1981, the temperature increase per decade is 0.31ºF or 0.17ºC. Since pre-industrial 1880-1900, 2018 is an increase of 1.75ºF or 0.97ºC above that average.
The world land, 29% of the world’s surface, was up 2.02ºF or 1.12º C from the 20th century average. The highest land temperature was in 2016 where it was up 2.16ºF or 1.45ºC over the 20th century average.
The contiguous US is 1.51ºF or 0.84ºC above the 20th century average, about a tenth of a degree F above the 1.42ºF or 0.79ºC above the global average. This 2018 over the US is the 14th warmest year of the 124 year record.
For Alaska, the is the 2nd warmest year, at 4.4ºF or 2.4ºC above the 20th century average. The warmest year was 2016 where Alaska was 5.9ºF or 3.3ºC hotter than the 20th century average.
For North America, 2018 was the 18th warmest, by 1.31ºF or 0.73ºC. Since 1981, the rate of increase per decade is 0.52ºF or 0.29ºC.
One of the slides shows the 14 US disasters that exceeded a billion dollars in 2018. There were $91 billion in direct losses in these disasters. This is the fourth largest total on record. Hurricane Michael cost $25 billion, hurricane Florence cost $24 billion, as well as western wildfires which also cost $24 billion. In 2017, just four hurricanes alone cost $336 billion: Harvey at $125 billion; Maria at $90 billion; Sandy at $71 billion; and Irma at $50 billion.
