As the planet continues to warm due to human activities, the frequency and intensity of extreme weather events are becoming increasingly alarming.From intense heat waves to devastating floods, climate change is reshaping weather patterns globally, leading to unprecedented challenges for communities and ecosystems.A significant driver of these changes is the rise in greenhouse gases in the atmosphere, primarily from the burning of fossil fuels.This anthropogenic influence is causing average global temperatures to rise, which has serious implications for extreme weather.According to NASA, the average global temperature has increased by approximately 1.9 degrees Fahrenheit since 1880, resulting in more severe heatwaves and other extreme weather events.

lung.orgClimate change is also influencing extreme cold events.Warmer temperatures can disrupt the polar vortex, resulting in frigid air masses moving further south than usual, leading to severe cold spells in regions that are typically warmer.This phenomenon underscores the complexity of climate change, which can lead to both extremes of temperature – hot and cold – depending on local conditions and weather patterns.
