The temperature trends in the Northeastern states were analyzed from a collection of sites in the GISS data set. The raw data set was used; all temperatures are in Celsius. Here are the locations used, with the annual average temperature for the first and last years in the GISS record and with several other data points for reference. The state is listed with its locations. Here is an Excel spreadsheet that shows the distribution of locations (to get a roughly similar square miles per location in each region). Here is a text file that lists the locations in all the states and a few samples of the temperatures. Here is a Word document with the links to the GISS data for all the locations, as well as the latitude and longitude (from GISS) for each location.

Since the anthropogenic global warming debate is about CO2 levels, here is a chart with the 10-year average temperatures in the Northeastern region plotted against the CO2 levels.



Tinkering with the respective scaling in the above chart can get overlaps of the two trends. However since the temperature trends go up and down while the CO2 level never goes down the two charts will never coincide.

This page shows the temperature trends for locations in this region. The expectation with AGW (global warming due to man-generated increasing CO2 levels) would be a continually increasing temperature. The expectation after recognizing historical higher and lower temperatures (due to solar sun spot cycles) would be a warming trend near the start of the 20th century, followed by a cooling trend in the second half of the century, followed by a recent warming trend.

Here are the annual average temperatures for these locations (grouped by state) with their 10-year average temperatures.





















































Locations across the Northeast region and the United States exhibit similar warming and cooling trends across the past century.

The day before I put this page on the site (the analysis had been done in the previous days), a study was released that identifies the presence of the urban heat island effect in the temperature record. Several of the locations above were noted in that study.
