Climate change, brought on by human activities like the burning of fossil fuels and deforestation, is making heat waves, droughts, wildfires, and floods more severe and frequent. The frequency and severity of these extreme weather events are increasing, and they have a profound impact on ecosystems, public health, and the world economy. These heatwaves are not only more intense but also last longer, posing serious health risks, including heatstroke and dehydration, particularly among vulnerable populations like the elderly and children. One of the most obvious effects of climate change is rising global temperatures, which cause more frequent and intense heat waves.

The accumulation of greenhouse gases in the atmosphere traps heat, resulting in an increase in world average temperature. As a result, heatwaves are becoming not only more powerful but also longer-lasting, causing serious health hazards such as heatstroke and dehydration, particularly among vulnerable groups such as the elderly and children. These heatwaves are not only more severe, but also longer in duration, causing major health hazards such as heatstroke and dehydration, particularly among vulnerable groups such as the elderly and children. Rising global temperatures are one of the most evident impacts of climate change, resulting in increasingly frequent and powerful heat waves.

The devastating floods of 2021 exposed the mounting risk in China and Germany. In conclusion, the data is clear: climate change is increasing the frequency and severity of extreme weather occurrences. The global community must act quickly and firmly to address the underlying causes of climate change and minimize its disastrous consequences. Failure to do so will have progressively negative effects on the planet and all of its people. The Dust Bowl of the 1930s in the United States, a period of severe dust storms and drought, was one of the earliest indicators of how climate variability could devastate agriculture and livelihoods. In 2024, India has been experiencing increasingly severe heat waves, with record-breaking temperatures becoming more frequent in recent years. These high-heat episodes pose serious health hazards, especially to vulnerable communities, and considerably impact agricultural and water supplies. In 2024, California saw one of its most disastrous wildfire seasons, with large-scale blazes driven by extended drought and hot weather. These flames caused significant devastation of houses and woods, necessitating large evacuations and emphasising the growing influence of climate change on fire behaviour.

This warming mechanism allows for extended periods of extreme heat. Temperatures have hit all-time highs in several parts of the world, including North America, Europe, and Asia. Droughts and heatwaves are inextricably linked, and climate change exacerbates both. When the temperature rises, soil and water bodies evaporate faster, making less water accessible. Global precipitation patterns are shifting, with certain places seeing lower-than-average precipitation amounts. Prolonged droughts harm ecosystems, water supplies, and agriculture. They are caused by shifts in precipitation patterns and rising temperatures. Droughts in the American Southwest, sections of Africa, and Australia have had a significant influence on food security and human life.
