Why Climate change is a cause of concern?

  • Climate change has several adverse health impacts, both direct and indirect.
  • Heat-related diseases triggered by extreme heat events, which are on the rise because of changing climate, are an example of direct health impacts of climate change.
  • Changing crop patterns, declining yields, water scarcity, and extreme precipitation are expected to have health consequences as well.
  • Food shortages and resultant malnutrition are considered major side-effects of rising temperatures.
  • The World Health Organization estimates that about 250,000 excess deaths are likely to be caused by climate change-induced factors — malnutrition, malaria, diarrhoea, and heat stress — between 2030 and 2050.
  • Higher temperatures have led to “increased dehydration and renal function loss, dermatological malignancies, tropical infections, adverse mental health outcomes, pregnancy complications, allergies, and cardiovascular and pulmonary morbidity and mortality”.
