Given that yearly variations in temperature are natural, I would have let this summer slip by as an exception. However, the intensity of the heat has left me stunned. For instance, Copenhagen, for at least one day, recorded a higher day temperature than Delhi. I should not have been that surprised though. Scientists have repeatedly warned that Europe will become a &lsquohotspot&rsquo for severe summer heat and predict the future heat waves will be longer, more frequent, and more intense.
