Truly urban cities often consume gigawatts of electricity and other source of energy. A new research suggests that such cities are also responsible for directly changing temperature trends, even in areas more than a 1,000 miles away.
The problem with densely populated urban regions is that the sheer bulk of commercial and residential services produce a significant amount of waste heat. That’s because such urban settings have heavy use of electronics, cutting-edge transport solutions and what not – each of them contributing to the magnanimous heat waste that accumulates as the collective output of such a city.
The results of such heat wastage are dire, as the new research suggests. This heat can affect the temperatures of not only surrounding regions but also regions as far away as a 1,000 miles. To cite an example, scientists reveal that certain regions of North America have grown warm by 1 degree Fahrenheit due to this phenomenon. Certain regions in Asia have grown warm by an even greater margin, 1.8 degree Fahrenheit to be exact.
Not only are the high-energy-consuming cities altering temperatures but also certain other weather trends. For instance, the heat wastage from such cities has been seen to be tampering with jet streams, which are strong and focused gusts of wind, blowing from west to east and north to south in the upper atmosphere.
Such effects of heat wastage on the weather are very significant and may account for the inaccuracy of earlier climate models. Most climate studies tend to leave out urban cities, but this new research shows that urban cities are quite directly responsible for at least some of the climate changes.
