BREAKING POINT: HOW CLIMATE CHANGE IS DRIVING MORE FREQUENT NATURAL DISASTERS

Flash flooding/Urban flooding in developed countries such as the UAE (Dubai), Saudi Arabia, Australia, Canada, the USA, and China underscores a significant issue: even the most advanced and well-planned urban environments are increasingly vulnerable to natural disasters.

INCREASING DISASTERS DUE TO CLIMATE CHANGE:

A Global Crisis Climatic Change: A Global Crisis Increasing rates and intensities of disaster events are being witnessed over the subsequent decades, and with intensification, the risk toward communities at large increases. The general understanding of scientists and experts is this dangerous trend has a root system anchored in climate change; again, an event process driven majorly by human activities. The consequences have been very deep, touching ecosystems, economies, and human lives at an unprecedented scale. It details the complex links between the climate change challenge and mechanisms with rising disaster incidence and examples, and why with this complexity, collective action is asked for. The Science Behind Climate Change and Disasters Climate change denotes the long-term changes in temperature, rainfall, and other related conditions in the atmosphere.

Mostly, these are mainly rectified by the addition of greenhouse gases and carbon dioxide and methane gases that emanate from activities like burning fossil fuels, deforestation, and production processes. Warming the planet develops some important processes that increase the intensity of natural disasters:

1. Rise in the Global Temperature: Globally Temperature is rising which increases the severity of weather such as the frequency of flash floods, storms, and disasters.

2. Melting of Ice and Rising sea levels. Glaciers are melting rapidly after the global temperature rise resulting the high sea levels and allowing the high risk of coastal flooding and sea erosion. However, the communities living along the coasts are at risk.

3. Changed Weather Patterns: Climate change shifts the weather patterns that have been well established with the effect that droughts that set in last much longer in some regions, while the levels of rainfall are found to be much higher in other regions. Such shifts would annihilate agriculture, water supply, and the general stability that the ecosystem has. Case Studies: Climate-Enhanced Disasters

I. Increasing Hurricanes and Typhoons: Increased intensity in a couple of years. Hurricanes, MARIA which destroyed PUERTO RICO in 2017, and TYPHOON HAIYAN which destroyed the PHILIPPINES in 2013. The estimated death tolls from these disasters were very high, together with the destruction of many infrastructures.

II. The Wildfires: Unprecedented number of wildfires in California, Australia, and across the Mediterranean. In 2020 California the wildfires, waved by the extreme heat and extended the drought situation, spread over the area of 4 million acres. Likewise, in Australia, the bushfires, caused by high temperatures, burnt an estimated 46 million acres within two years from 2019 to 2020 and also killed about 3 billion animals overall.

III. Flash Flooding: Flash flooding has increased global impacts in recent years. In 2022, the flash flooding in Pakistan affected over 33 million people, displaced over 20 million, and destroyed more than 2 million houses, infrastructure, and farmland. That has been facilitated by the most extensive manifestations of monsoon rains and a changing climate. The Heavy rainfall/flash flood in the Middle East brought the worst flooding ever experienced in areas that were not expected to normally experience such spells. The Heavy rains this year caused devastating floods in Dubai, the UAE, and Saudi Arabia, affecting daily life, exposing the infrastructure, and, more importantly, bringing out the vulnerability of this region to extreme weather conditions due to climate change.

4. Droughts: Extended droughts are very detrimental to both water security and agriculture. The Horn of Africa has greatly suffered related to consecutive droughts that have led to food insecurity and displacement of populations. Similarly, in California and the Disserted areas of Pakistan, recurrent continuous droughts resulted in extreme stress on water resources, causing an impact on agriculture and large losses in terms of economics. The Human and Economic Toll The cost of climate-related disasters in human lives is so high: loss of life and property, with populations getting displaced. The toll is particularly high on vulnerable populations, especially in developing countries but also in those lacking the means to be used for effectual response and recovery. The economic costs also build up high, running into hundreds of billions and counting for disaster response, recovery, infrastructure repair, and mitigation efforts. Apart from triggering loss of biodiversity, decreased agricultural productivity, and increased health risks due to vector-borne diseases and malnutrition, the break in the supply chain, together with the impact on food production and overburdening of health, will cause long-term effects. Urgency of Action Increased climate-induced disasters amount to a multidimensional challenge:

I. Mitigation: The need to reduce the emissions of greenhouse gases by adopting energy from renewable sources, promoting energy efficiency, and conserving forests as a sink of carbon.

II. Adaptation: Community resilience building, with infrastructure, advanced early warning systems, and practices of sustainable agriculture.

III. International Cooperation: It is an international issue, so it should be managed like a problem by all. International agreements, like the Paris Agreement, act in tandem, setting goals for reduction in emissions, then.

IV. Public Awareness and Education: This provides for increasing awareness of the impacts of climate change and the importance of sustainable practices that drive individual and collective action.

V. Research and Innovation: Researching climate change to understand it and coming up with innovative solutions to the same is very critical. That includes the improvement in climate modeling, development of carbon capture technologies, and encouraging sustainable development practices.

 Conclusion: The Increase in the intensity of natural disasters caused due to climate change is among the biggest challenges faced by global humanity today. The pieces of evidence are clear and convincing that human activities are altering the planet Earth's climate and devastating the consequences.  Urgent and coordinated action at both local and international levels is imploringly important. Lower emissions, enhanced resilience, and international cooperation are the key factors toward a sustainable and secure future. The time to act is now before the mounting costs render it impossible to act.
