Write an Essay On Climate Change
Answers
Answer:
Climate change in the world can be caused by various activities. When climate change occurs; temperatures can increase a dramatically. When temperature rises, many different changes can occur on Earth. For example, it can result in more floods, droughts, or intense rain, as well as more frequent and severe heat waves. 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. Most of the gases come from burning fossil fuels to produce energy. Greenhouse gases are like a blanket around the Earth, trapping energy in the atmosphere and causing it to warm. This is called the greenhouse effect and it is natural and necessary to support life on earth. However, while greenhouse gases buildup, the climate changes and result in dangerous effects to human health and ecosystems. People have adapted to the stable climate we have enjoyed since the last ice age which ended several thousand years ago. 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.
Answer:
Climate is an average of atmospheric conditions over a long period. Generally, climate is determined from the average weather conditions of summer, winter and rainy season of a place for about 35 years or more. In short, climate is an average of long term atmospheric conditions.
Weather is an average of short term conditions of atmosphere. Weather can change at any time during a day. Change in weather conditions depends on air temperature, air pressure, humidity, rain, fog or amount of clouds etc. Weather affects our daily agricultural activities. Indian meteorological department publishes a daily weather map and a report of the entire nation.
India shows a large diversity and characteristics in climate conditions. Season change in some parts of the earth according to the wind direction. So the winds which change their direction according to the season are called 'Monsoon winds'. These winds are so named after the Arabic word 'Mausim'. India, Sri Lanka, Bangladesh, Pakistan and Myanmar are Asian countries which experience monsoon climate.
