what is global warming?
Some folks think the Earth is getting warmer, both because of man's activities and natural causes, and that disaster for mankind and civilization will result
every one have to join hands to save our planet and more eco- friendly technologies should be introduced rather than cause harm to our mother earth......more trees have to be planted (10 trees for every one tree cut)
Global warming refers to the long-term increase in Earth's average surface temperature due to the accumulation of greenhouse gases in the atmosphere. These gases, such as carbon dioxide (CO2) and methane (CH4), trap heat from the sun and prevent it from escaping back into space, leading to a warming effect.
To understand global warming, we can break it down into the following steps:
1. Greenhouse Effect: The Earth's atmosphere naturally contains greenhouse gases that help regulate temperature by trapping some of the sun's heat. This natural greenhouse effect is essential for sustaining life on Earth.
2. Enhanced Greenhouse Effect: Human activities, primarily the burning of fossil fuels like coal, oil, and natural gas, have been releasing large amounts of carbon dioxide into the atmosphere. Deforestation and industrial processes also contribute to increased greenhouse gas emissions. As a result, the concentration of these gases has been rising rapidly, enhancing the natural greenhouse effect.
3. Rising Global Temperatures: The increased concentration of greenhouse gases traps more heat in the atmosphere, causing the average temperature of the planet to rise over time. This phenomenon is known as global warming.
4. Impacts: Global warming has far-reaching effects on the environment, ecosystems, and human society. It leads to melting glaciers and polar ice, rising sea levels, more frequent and severe heatwaves, changes in weather patterns, habitat loss, and disruption to ecosystems. It also poses numerous threats to human health, agriculture, water resources, and increases the frequency and intensity of natural disasters.
To understand the concept of global warming, it is crucial to examine scientific research, analysis of climate data, and the consensus among climate scientists. Sources like the Intergovernmental Panel on Climate Change (IPCC) provide comprehensive reports on the subject, summarizing the latest scientific knowledge on global warming.
