More frequent heat waves are an obvious side effect of global warming, but higher temperatures also mean deadly droughts and wildfires. Water evaporates faster under such conditions, creating water shortages, leaving soil dry, and putting crops and livestock at risk. Hot, dry weather is also ideal for sparking wildfires, and scientists have traced a link between a warmer planet and the recent increase in wildfires.
Doctors warn that global warming will also create more heat-related deaths from cardiovascular problems and strokes. Young children and the elderly will be especially vulnerable to higher temperatures.
