Coldest Year On Record In Maryland So Far – 12C Colder Than 1921

My local weather station (like most of the US) is having its coldest year on record so far, and is an astonishing 12ºC colder than 1921.

    You’ll love this – Mann has just linked approvingly to an article arguing that climate sensitivity is 6 degrees C.

    • Anto says:

      To quote from Mann’s link:

      NASA’s James Hansen, however, has convincingly shown that the sensitivity number is low by half if you also include slow feedbacks like loss of reflective sea ice and, yes, melted Arctic methane. To make that real — if Hansen is right and we succeed in doubling atmospheric CO2 from the stable pre-industrial level of 280 ppm to 560 ppm, and then stop, we’ll have handed ourselves +6°C global warming, guaranteed,

      Michael Mann is the answer to the rhetorical question posed by the question posed here

    This year’s temps are obviously extremely cold — but that high temp in 1921 is astonishing! Any ideas about that? Is that a reliable data point? If so, it says a lot about fat tail distributions and weather variability.

  3. Wow, that looks like an error to me. Now I know how to check it (but it will be a few days). Maryland is small, I wonder what Delaware looks like…

    This appears to be a semi smoking gun that validates what I have been saying about National Airport’s significant warm bias. National is located approximately 20 miles south of Laurel. For the year, National has only averaged about -1C, while Laurel has been averaging around -3C. I don’t think there has been much of a north/south gradient with respect to temperature departure, certainly nowhere remotely that large.

    Also, it appears that there has been no warming at Laurel since the 1950’s. During the 1950’s, Laurel was a tiny rural town. Today it is a densely populated part of the DC/Baltimore suburban sprawl. Assuming the location has been contant, if you were to do any adjusting, it would be to cool the present and warm the past. Just the opposite of what they are doing!

    Back in the early 90’s I had a job just a few miles away from Laurel in Glen Burnie. I worked late every Friday night and had to take all the work orders and invoices from the week to the 24 hour Express Mail office at BWI airport on my way home to send to the main office.

    There were two Winters in a row back then where the temperature went down into the single digits at night in downtown Glen Burnie. By the time I drove to the airport just two or three miles away the air temperature would go down another five degrees, every time, to around zero.

    Now that same area where there was nothing but small auto repair garages, trees and wide open fields is a mass of airport parking lots, Arundel Mills Mall, thousands of new houses and Maryland Live Casino.

    This past Winter on one of the coldest nights I was out really late in that area and decided to see how low I could get my car’s thermometer to go by driving down that same road. The temperature went up one degree from downtown to the airport loop.

    Keep in mind that the official temperature for this entire area is recorded about 2000 feet away from that spot.

    My kid’s mother lives in Maryland and it was the first time her water pipe froze from the outside

    Couldn’t happen to a nicer person
