Wednesday January 9th… Dear Diary. The main purpose of this ongoing post will be to track United States extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials)😊.
Hottest Years For U.S. Cities
Today I am pleased to announce that Climate Central has completed compiling statistics ranking the hottest years for many large cities across the U.S. through 2018. I’m humbled to have been considered for contributing to Climate Central’s statistics during this decade. I’m reposting Climate Central’s hottest years for U.S. Cities article released today, January 9th for all to read and scientifically judge. It’s no surprise that most cities had their hottest year recently given warming trends due to carbon pollution:
For most places in the U.S., the hottest year on record has come during the current decade. As an example: Atlanta
Most U.S. cities notched their hottest year on record in the 2010s. See what year came in on top for Atlanta https://buff.ly/
To get the above nifty chart for a large city near you see: http://www.climatecentral.org/gallery/graphics/hottest-years-for-us-cities
The 2018 U.S. temperature analysis from NOAA has been delayed due the federal government shutdown. We will bring you the information once it’s released. In its place this week, we calculated the average annual temperatures at 244 individual U.S. stations throughout their periods of record, highlighted the decade in which each record hot year was established, and showed the breakdown of each station’s records by decade.
Only one place in our sample had its hottest year on record in 2018 — Palm Springs, California. On the broader scale, 2018 is the first time since 2014 that the U.S as a whole did not have one of its 10 hottest years. Of the stations analyzed, 53 percent experienced their hottest year during the decade of the 2010s, consistent with this being the hottest decade on record in the U.S. This far exceeds the second-place decade of the 1930s, when 18 percent notched their hottest year on record. Periods of record vary, but 70 percent of stations were active by the 1930s and 96 percent were active by the 1960s.
Despite a cooler than normal November, 2018 was still running way above average — year-to-date temperatures through November were 16th warmest on record. Through December 22, the last day before the government shutdown made data inaccessible, the number of daily record highs in 2018 outnumbered the number of daily record lows by a ratio of 1.68-to-1. That ratio may not be as dramatic as in recent years, but even with local short-term warming and cooling, overall warming from the buildup of greenhouse gases in the atmosphere continues to drive the long-term temperature trend.
(I’m adding this graphic for reference to Climate Central’s last paragraph):
Data was gathered from the Applied Climate Information System. Average annual temperature was determined using the average of days (not the average of months). Years with more the 30 days of missing data were removed from the analysis. In case of a tie (22 occurrences), the most recent year is represented. Former Weather Channel meteorologist Guy Walton maintains a comprehensive records database, analyzing monthly, annual, and decadal records trends.
I invite all to peruse Climate Central’s database to see where your nearest large city ranks.
Here is some more climate and weather news from Wednesday:
(As usual, this will be a fluid post in which more information gets added during the day as it crosses my radar, crediting all who have put it on-line. Items will be archived on this site for posterity.)

Impressed and sad to see a very popular children’s book talk at length about climate change. I wonder what children’s books will cover 100 years from now? #ClimateCrisis #climatechange #ClimateBreakdown #diaryofawimpykid @MichaelEMann @EricHolthaus @ClimateBen pic.twitter.com/W4fmm4B5bs

The Camp Wildfire was the costliest natural disaster in the world last year, followed Hurricanes Michael and Florence.
These three most expensive natural disasters in the world last year were each weather-related tragedies occurring in the US. https://t.co/grQLMNAwt6

Yes….! This is one of the best, fairest, and most accessible overviews of climate modelling available. I recommend this piece, and @CarbonBrief in general, as a go-to resource. @LeoHickman @hausfath https://t.co/juCdbETFme

Very hot conditions are building over #WA and northern parts of the country. The heat will then move towards the east late in the week, with low to severe #heatwave conditions extending across most States into the weekend. #Summer https://t.co/xwqUJmcT0c pic.twitter.com/Fu3KzMYfGB

For the "myths", go to 9:45 into the segment.
