Assessing the Rate of Warming Across Parts of the United States of America (credit: Climate Central)
DISCUSSION: As the global meteorological community continues to discuss issues pertaining to planetary warming trends, it is important to keep in mind that some places are statistically being more impacted than others over the course of time. As shown in the graphic above (courtesy of the Climate Central research group), a good portion of the North-Central and Northeastern United States have been more notably impacted by the effects of gradual planetary warming issues. Even more specifically, some cities (including but not limited to) Burlington, Vermont and Mankato, Minnesota have experienced average temperature increases of just over 6°F per decade. Thus, towns and cities situated across the northern tier of the United States have undoubtedly encountered more dramatic temperature increases over the course of the last 30 to 40 years and counting.
The best explanation for this northern-biased temperature increase is due to the fact that this part of the United States has such a dramatic average temperature change between Spring/Summer-time and Fall/Winter-time that there is a greater signal for average temperature change over the course of time further north. On the contrary, the further south that one goes, there was less of a notable average temperature change per decade likely due in part to the fact that season-to-season temperature variability does not vary quite as much. Thus, over the past 30 to 40 + years, there was less of a longer-term average temperature change. The only other part of the country which this was also the case across portions of the Inter-Mountain Western United States; though the signal was closer to neutral longer-term temperature variability. In all likelihood, this was due to natural inter-decadal variability coupled with gradual planetary warming influences and you can also see how parts of the Rocky Mountains are also within this region of near-neutral long-term temperature variability.
