Ground Report | New Delhi: What is Global Warming?; Rising global temperatures increase the risk of hurricanes, floods, wildfires, droughts, and heatwaves. In hot climates, the atmosphere can collect more water and cause severe rain.
What is global warming or an increase in global temperature?
Global warming refers to the increase in average global temperature since the Industrial Revolution. The average global temperature has increased by about one degree Celsius since 1880. Global warming is an ongoing process, with scientists fearing that the average global temperature could rise an additional 0.3 to 0.7 degrees Celsius by 2035.
What is the cause of global warming?
Some gases, such as carbon dioxide and methane, trap the Sun’s heat in Earth’s atmosphere. These greenhouse gases (GHGs) are also naturally present in the atmosphere. Carbon dioxide and other greenhouse gases are released into the atmosphere by human activities, especially the burning of fossil fuels (i.e., coal, natural gas, and oil) in electric vehicles, factories, and homes. Other activities, including cutting trees, also emit greenhouse gases.
The high concentration of these greenhouse gases in the atmosphere is responsible for increasing more heat on the earth, leading to an increase in global temperature. Climate scientists believe that human activities are the main reason behind global warming.
Is climate change different from global warming?
According to the Institute for Environmental and Energy Studies, climate change and global warming are often used interchangeably, but climate change is broadly related to mean weather (e.g., temperature, precipitation, humidity, wind, atmospheric pressure, ocean temperature). ) is related to. , etc.) whereas global warming is known to increase the average global temperature of the earth.
Is Global Warming Dangerous Weather, Hurricanes, Heatwaves, Droughts, and Floods?
Rising global temperatures increase the risk of hurricanes, floods, wildfires, droughts, and heatwaves. In a warmer climate, the atmosphere may collect more water and precipitation, causing changes in rainfall patterns. Agriculture may benefit from increased rainfall, but more intense storms in a single day can cause damage to crops, property, infrastructure, and loss of life in affected areas.
This also causes sea surface temperatures to rise as most of the heat in Earth’s atmosphere is absorbed by the ocean. Warmer sea surface temperatures make it easier for hurricanes to form. Due to human-caused warming, it is feared that hurricanes will increase precipitation rates, increase hurricane intensity, and increase the proportion of storms that reach Category 4 or 5 levels.
Rising sea level?
Global warming contributes to sea level rise in two main ways. First, warmer temperatures cause faster melting of glaciers and land-based ice sheets, which carry water from land to the ocean. Ice melting regions around the world include Greenland, the Antarctic, and mountain glaciers.
According to the United Nations Framework Convention on Climate Change 2019, global warming could cause 80 percent of glaciers to melt and shrink by 2100. Second, heat-related (thermal) expansion, the process by which warmer water takes up more space, increases the volume of the ocean, leading to sea-level rise.
Other factors affect sea level, and the combination of all these factors causes varying rates of sea-level rise across the planet. Local factors that cause a rapid sea-level rise in some areas include ocean currents and sinking land surfaces.
