CLIMATE CHANGE IN PAKISTAN 2022

Climate change in the world can be caused by various activities. When climate change occurs; When temperature rises, many different changes can occur on Earth. Oceans and glaciers have also experienced some changes: oceans are warming and becoming more acidic, glaciers are melting, and sea levels are rising. As these changes frequently occur in future decades, they will likely present challenges to our society and environment.
During the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. However, while greenhouse gases build-up, the climate changes and result in dangerous effects to human health and ecosystems. A warmer climate can bring changes that can affect our water supplies, agriculture, power and transportation systems, the natural environment, and even our own health and safety. There are some climate changes that are unavoidable and nothing can be done about it. For example, carbon dioxide can stay in the atmosphere for nearly a century, so Earth will continue to warm in the future.The earth climates nowadays are changing very rapidly and differently. Besides that, the climate changes in our earth are affecting our lives psychologically, physically and emotionally.
What is climate change? Climate change is the seasonal changes for a long period of time in the world. For example, the changes in climate can affect how people, plants and animal live, such as food production and health risks. As the earth’s climate is dynamic and always changing through a natural cycle, the world is now worried about the changes that occurring today have been speeding up and seriously affecting human’s lives. All across the world, people are taking action to prevent climate change. For example, in 2007, scientists from the International Panel on Climate Change (IPCC) predicted that warming oceans and melting glaciers due to global warming and climate change could cause sea levels to rise 7-23 inches by the year 2100. Because of this, we must take action as soon as possible to try to solve this problem or to prevent the more serious of climate changes occur. I’m interested in this topic because the climate changes in our country or this world are too serious and it’s interesting to discuss and try to fix the problem.There are two main causes of climate changes – natural causes and human activities. Natural causes have influenced the earth’s climates such as volcanic eruptions, ocean current, the earth’s orbital changes and solar variations. This is because the bouncing of sunlight to the space is cooling the atmosphere of the earth.
All the causes are giving a great impact for climate changes in our earth. What are the consequences of these causes for the climate changes to our world? We can see that there are three main effects on climate changes in our environment. Firstly, climate change in the world will affects human health. There are so many past researches showed that climate change will leads to human health and producing diseases. For example, in the research paper by Healey et al., 2010 that I have read said that “the climate change is affecting the health of northern people such as Nunavut, Canada.” Besides that, Cecchi et al. (2010) have conducted the research on the effects of climate change on allergic asthma. Moreover, Mickley, 2007 stated that “high levels of surface ozone and particles have been implicated in many diseases involving the cardiac and respiratory systems.” These researches showed that the climate changes are seriously affecting the human’s health.
Secondly, climate changes will also affect the biodiversity. The climate changes have impacted the loss of biodiversity. For example, the water sources may change, the food chain may destroy and the medicine sources may change. Some of the factors that have an effect on climate, like volcanic eruptions and changes in the amount of solar energy, are natural. Climate can change if there is a change in the amount of solar energy that gets to the Earth. When snow and ice melts Earth’s climate warms, less energy is reflected and this causes even more warming. Cars and trucks can affect climate by releasing carbon dioxide when fossil fuels are burned to power them. Some effects that scientists have predicted in the past would result when global change was occurring: loss of sea ice, accelerated sea level rise, and more intense heat waves. The Intergovernmental Panel on Climate Change (IPCC) stated that the extent climate change effects on individual regions will vary over time and with ability of different societal and environmental systems mitigate or adapt to change (The Intergovernmental Panel on Climate Change). The rising of temperature will have great effects on the earth’s climate patterns and on all living things. If everybody as one take stand and try to end most of the climate changes that are occurring, this world would be a safer place to live on.
