Climate Change Drives Extreme Weather: Increased Rainfall Variability and Stronger Typhoons Reported. Scientists have found that climate change is causing more extreme fluctuations in rainfall patterns, impacting about 75% of the world's land area, Reuters reports. Recent powerful typhoons hitting Taiwan, the Philippines, and China illustrate the trend of fewer but more intense storms due to global warming. Rising global temperatures enhance the atmosphere's ability to hold moisture, leading to greater variability in precipitation, including more intense wet and dry periods. This variability in rainfall heightens the risk of severe weather events like droughts and floods, posing significant challenges for impacted regions. A study published in the journal Science, led by Zhang Wenxia, reports that warming temperatures are increasing atmospheric moisture capacity, contributing to unpredictable weather patterns. While the frequency of tropical storms may be decreasing, their intensity is increasing, resulting in more powerful and potentially destructive storms. Typhoon Gaemi, the strongest to hit Taiwan in eight years, exemplifies the increasing strength of storms linked to warming sea surface temperatures. Climate reports from China and Taiwan note fewer typhoons but increased intensity, attributed to uneven ocean warming patterns. Experts predict that a 1°C rise in global temperatures could increase atmospheric water vapor capacity by 7%, significantly boosting tropical cyclone rainfall and associated risks. The findings underscore the need for global efforts to mitigate climate change, as the increasing frequency and intensity of extreme weather events pose growing threats to communities worldwide.
