As the disputes on global warming and climate change rage on at various levels, I checked the minimum, average and maximum temperatures in Istanbul in March 2017. This year’s temperatures seem to be higher than the 90-year averages (1926-2016).
According to the State Meteorological Office, the historical minimum, maximum and mean temperatures were 4.2, 10.9 and 7.7 degrees centigrade. This year, however, these temperatures were 6.194, 14.19 and 10.23 degrees respectively.
This year’s warmer temperatures may not seem to be very meaningful in and of themselves; however, considering that the overall context is a hot issue (no pun intended), there may be enough reason to worry about the higher temperatures of this year, as these may be evidence for the much feared global warming.
After a long and wet winter here in Istanbul, where grey, dull and gloomy skies are quite typical, and where you feel the humid chill right in your bones, we finally felt it was a blessing to have the spring. Come May, the judas trees, tulips and all the verdure around the city suddenly created an aura of joy and relaxation (save for the political atmosphere), almost imposing an untimely restfulness.
Unfortunately, that did not last very long. Just as we thought we were easing into the summer we found ourselves hit over the head by temperatures hovering around 25 degrees Celcius, almost as oppressive as it usually gets in August.
That is certainly welcome considering the outrageous heating bills or not having to worry about a summer with dwindling water in the reservoirs(the summer of 2007 is still in memory!).
However, as the specialists indicate, weather anomalies cannot be ignored. With global temperatures rising and the arctic ice pack retreating and becoming thinner, and the antarctic glaciers moving into the ocean more quickly than before (http://www.sciencemag.org/content/348/6237/899), here is some food for thought for those who are interested. The chart below indicates weather anomalies based on data from the NOAA. If the trend of the 20th century is any indication, we are heading towards some real hot years.
