Understanding the Climate Connection
The Science Behind Extreme Weather
How Climate Change Intensifies Weather Events
Okay, so basically, climate change , driven by greenhouse gas emissions, is like cranking up the heat in the atmosphere. This extra heat supercharges weather systems, leading to more intense and frequent extreme weather events.
Imagine a pot of water on the stove. As you heat it up, the water starts to boil more vigorously. Similarly, as the Earth's atmosphere warms, it holds more moisture, fueling more intense rainfall and floods. Warmer temperatures also lead to longer and more severe droughts, creating conditions ripe for wildfires. Beneran deh, it's a domino effect!
Research shows that every degree Celsius of warming increases the atmosphere's capacity to hold moisture by about 7%. This extra moisture contributes to heavier rainfall, increased flooding risks, and more intense storms (Trenberth, K. E., et al. "Atmospheric moisture residence times and recycling: Role of advection and surface evaporation." Climate Dynamics 29.1 (2007): 19-38.).
Types of Extreme Weather Events
Heatwaves
Heatwaves are periods of abnormally high temperatures, often lasting for several days or even weeks. They can have severe consequences for human health, particularly for vulnerable populations such as the elderly and those with pre-existing medical conditions. Heatwaves also put a strain on infrastructure, leading to power outages and water shortages.
Floods
Floods are one of the most common and destructive types of extreme weather events. They can be caused by heavy rainfall, overflowing rivers, or storm surges. Floods can inundate homes and businesses, damage infrastructure, and displace communities.
