From listening to Romm, you would think that the US is having a very hot year. He has claimed heat from coast to coast.
But NOAA data shows Romm’s folly.
The map above is based on the NOAA year to date map. I split the country up into regions based on above normal (red,) normal (green,) and below normal (blue) temperatures. Normal is defined as within 1ºF of the mean temperature.
61% of the country has seen normal temperatures, 27% has seen above normal temperatures, and 13% has seen below normal temperatures. Hardly what would be called a hot year
According to NCDC, the year to date is actually the fourth coolest since 1998, with temperatures declining at a rate of nine degrees F per century.
So what is special about 1998? That is the year which USHCN/GISS promoted to #1 a few years ago, and is now listed as the hottest year ever in the US.
1934 used to be the hottest year, before GISS did their temperature gymnastics. Below is the US Weather Bureau map for July, 1934. The whole country was hot.
In June, 1934, the whole country had temperatures over 100 degrees.
So how about the East Coast? Is it the hottest year ever? Hardly – 1828 was hotter when CO2 levels were 284 ppm.
Conclusion : Romm’s claims are based on a complete lack of both near and long-term historical perspective.
