If we do not cut carbons emissions, 74% of the world’s population will suffer. According to a study published in the science journal Nature Climate Change, nearly a third of the world’s population suffered a deadly heat wave in the year 2000. Modeling and simulations of future climate change outcomes found reducing greenhouse gas emissions by the end of the century revealed 47% of the global population will still suffer from a deadly heat wave lasting more than 20 days. Without reducing carbon emissions, that number would climb to nearly 74%. There have been several deadly heat waves in the past few decades; in July 1995 a heat wave hit Chicago, killing more than 700 people. Russia suffered a record heat wave in the summer of 2010, killing more than 10,000 people.
The world is going through an extremely hot year, with the summer heat coming earlier than usual. India suffers from high temperatures every summer, as more than 1.3 billion people are poor, and 25 percent of the population has no electricity having to rely on “soil methods” such as Onions and salty milk. Last month, 167 people died of heatstroke and dehydration in the southern state of Telangana. Analysis of Indian meteorological data from 1960 to 2009 showed that when the average temperature in the summer in South Asia went from 27 ℃ to 27.5 ℃, the probability of the heat wave killing more than 100 people was increased from 13% to 32%. Forecasts by the end of the century show the low latitudes with average temperatures in the Middle East and South Asia countries will rise 2.2 ℃ to 5.5 ℃ – consequences that are worrying.
