Why would you assume that some numbskull running an anti-climate change website would tell you the truth. That chart is a lie. NOAA has only been recording the temperature using USHCN stations since 1983.

Since 1987, the National Oceanic and Atmospheric Administration's National Centers for Environmental Information (NCEI-NC) has used observations from the U.S. Historical Climatology Network (USHCN) to quantify national- and regional-scale temperature changes in the conterminous United States (CONUS). To that end, there are corrections to USHCN temperature records to account for various historical changes in station location, instrumentation, and observing practice. The USHCN is actually a designated subset of the NOAA Cooperative Observer Program (COOP) Network the USHCN sites having been selected according to their spatial coverage, record length, data completeness, and historical stability. The USHCN, therefore, consists primarily of adjustments for systematic, nonclimatic changes that bias temperature trends of monthly temperature records of long-term COOP stations.

Another bogus list of data from a bogus site.

But but but, his source about Washington DC weather comes from a bona fide high school student!


A high school student @2050Age tweeted first day of spring DC temperatures yesterday, showing how they have declined.


LMFAO
