We frequently hear news about unusual weather patterns and increasing natural disasters around the world. Everyone is puzzled as rainfall intensifies in arid deserts and tropical lands swelter under the scorching heat of the sun.
Climate change is inevitable over time. However, the rate at which these changes are occurring is concerning. What previously took a century to unfold now happens within a decade, and what occurred over a decade is now happening nearly every other year.
In an unpredicted turn of events, the United Arab Emirates (UAE), a dry and hot nation that receives annual rainfall of around 100 mm, experienced double that amount in a single day. Marking the largest recorded rainfall in the country's history. The aftermath was chaotic, with floods drowning many parts of the nation, deserts transformed into waterlogged landscapes, and hailstorms adding more to it. Neighboring countries, Saudi Arabia, Bahrain, and Oman, also received heavy rainfall.
Amidst the confusion, there were claims circulating that the UAE's cloud seeding activities were responsible for the disastrous weather conditions. However, government officials confirmed that cloud seeding had no influence on the recent rainfall. Cloud seeding is a weather modification technique wherein substances like natural salts are dispersed into clouds to stimulate rain. Despite the dismissal of cloud seeding as a cause, concerns loom over the future weather patterns in the UAE .Predictions suggest that the country may face even more severe rainfall in the future.
In contrast to the UAE, India, a country once known for pleasant tropical weather and abundant rainfall, is grappling with a new reality: scorching heat. Unprecedented heatwaves and droughts are disrupting daily life, with tragic consequences. On April 16 alone, 13 people lost their lives in Navi Mumbai due to heat exposure at a public event.This dramatic shift highlights the very real threats of climate change in India.
In Mumbai, the recent presence of an anticyclone has triggered a series of significant weather phenomena. Anticyclones, characterized by high atmospheric pressure, induce downward- moving winds that compress and heat up the air, often culminating in widespread heatwaves. The city experienced a localized "heat dome" effect, intensifying the already warm temperatures. Moreover, the sinking motion associated with the anticyclone drew warm air from regions like West Asia and the Arabian Sea, amplifying humidity levels, particularly in the buildup to the monsoon season. Typically, Mumbai benefits from cooling sea breezes at night, but the presence of the anticyclone seemingly impeded this natural cooling mechanism, resulting in unusually high nighttime temperatures.
Kerala is also currently experiencing one of the hottest summers in its history, with temperatures soaring to record levels. The recent surge in temperatures across Kerala has caused widespread concern, leading to school closures and reports of health issues such as sunburns and heat-related illnesses, even cases of fatalities. Residents are confused by the unusually hot weather and are seeking explanations. While natural weather phenomena like El Niño, which involves warming sea surface temperatures in the Pacific Ocean, can contribute to temperature fluctuations, human-induced climate change is also playing a significant role in the observed temperature spikes.
Let's delve into some of the reasons why these climate changes are occurring with such urgency and frequency.
Rising temperatures due to climate change have significant implications for weather patterns worldwide. As temperatures increase, evaporation rates rise not only from land but also from oceans and other water bodies, filling the atmosphere with more moisture. Studies indicate that for every 1 degree Celsius rise in average temperature, the atmosphere can hold approximately 7% more moisture, leading to intensified storms characterized by increased precipitation intensity, duration, and frequency. This heightened precipitation poses a severe flooding risk. In regions like India and the UAE, human-induced global warming, compounded by temporary influences like El Niño, amplifies extreme weather phenomena such as intense heatwaves in India and heavy rainfall in the UAE.
Despite clear warnings from climate activists and scientists about the drastic impacts of global warming, nobody anticipated the severity and immediacy of its effects to such an extent. The seemingly minor indications of global warming are spreading chaos globally, and we have yet to witness the full extent of its consequences.
The recent climate changes in the UAE and India highlight the intricate dynamics between natural phenomena and human activities, emphasizing the urgent need for a global approach to address climate challenges. By implementing sustainable development practices, building climate-resilient infrastructure, and enhancing disaster management strategies, we can uphold global resilience and sustainability in the face of evolving climate patterns. It's crucial to prioritize understanding and minimizing the impacts of climate change to safeguard the well-being of communities worldwide.
