A study in the geophysical research letters journal found that summer in the Northern Hemisphere midlatitudes has lengthened, whereas winter has shortened, owing to shift in their onsets and withdrawals, accompanied by shorter spring and autumn. Over the period of 1952–2011, the length of summer increased from 78 to 95 days and that of spring, autumn and winter decreased from 124 to 115, 87 to 82, and 76 to 73 days, respectively. Our health and well-being are inextricably linked to our natural environment. So much, in fact, that the World Health Organization has called climate change “the single biggest health threat facing humanity.” The link between changing climate and erratic weather is clearer than ever. Join us as we dive into the complicated game of predicting seasonal changes!
