Impacts include glacier melting, sea-level rise, extreme weather, and threats to food and health; Nepal faces heightened glacial lake flood risks. Mitigation requires renewable energy, forest protection, and international cooperation. ## Answer **Global Warming: A Growing Problem of the Present-Day World** *Rojina Basnet, Department of Environmental Engineering* #### Abstract Global warming is the long-term rise in the average temperature of the Earth's surface due to human activity. This article reviews its causes, effects and possible solutions, using reports of the Intergovernmental Panel on Climate Change (IPCC). It shows that the burning of fossil fuels is the main cause and that the global temperature has risen by about 1.1 degrees Celsius above the pre-industrial level. The effects include melting glaciers, rising seas, extreme weather and risks to food and health. Mountainous countries such as Nepal are especially vulnerable. The article recommends reducing emissions, adapting to the change, and international cooperation. **Keywords:** global warming, climate change, greenhouse gases, glaciers, Nepal #### Introduction The Earth is warmed by the sun, and certain gases in the atmosphere, called greenhouse gases (carbon dioxide, methane and nitrous oxide), trap some of this heat. This natural greenhouse effect makes life possible. But human activities have increased the amount of these gases and so raised the temperature, a process known as global warming. It is now one of the greatest problems facing humankind. #### Causes 1. Burning of coal, oil and gas for electricity, transport and industry. 2. Deforestation, which reduces the absorption of carbon dioxide. 3. Agriculture, especially livestock and rice fields, which produce methane. 4. Industrial gases, and waste decomposing in landfills. According to the IPCC (2023), human activities have raised the global surface temperature by about 1.1 degrees Celsius above the 1850-1900 level. #### Effects - **Melting ice and rising seas:** glaciers and polar ice are melting, and rising seas threaten coastal cities and islands. - **Extreme weather:** heatwaves, floods, droughts and stronger storms are becoming more frequent. - **Food and water:** crop yields and water supplies are affected. - **Health and ecosystems:** diseases spread to new areas, and many species are in danger. - **Nepal:** the Himalayan glaciers are shrinking, increasing the risk of glacial lake outburst floods and landslides and changing monsoon patterns, even though the country contributes very little to global emissions. #### Solutions 1. Shift to renewable energy such as solar, wind and hydro, and use energy efficiently. 2. Protect forests and plant trees. 3. Promote public transport and electric vehicles. 4. Reduce waste and adopt sustainable farming. 5. Follow international agreements such as the Paris Agreement, and help poor countries with finance and technology. 6. Educate people and encourage a low-carbon lifestyle. #### Conclusion Global warming is real, caused largely by humans, and already affecting the world. Its seriousness requires immediate action by governments, industries and individuals. The sooner emissions are cut, the less damage future generations will suffer. #### References - Intergovernmental Panel on Climate Change. (2023). *Climate change 2023: Synthesis report*.

What makes the natural greenhouse effect different from global warming? A. Natural effect makes life possible; human activity has increased greenhouse gases and raised temperature B. Both are caused only by volcanoes C. Global warming is cooling D. Greenhouse gases do not trap heat Answer: A. The natural effect keeps Earth habitable, while extra human emissions cause global warming. (Key point: Meaning and mechanism) 2. What is the main cause and the temperature rise cited from IPCC? A. Burning fossil fuels; about 1.1 degrees Celsius above 1850-1900 B. Deforestation only; 5 degrees C. Solar activity; 0.1 degrees D. Landfills only; 10 degrees Answer: A. Burning coal, oil and gas is the main cause, with about 1.1 °C rise above the 1850-1900 level. (Key point: Main cause and figure) 3. Why is Nepal especially vulnerable although it emits very little? A. Shrinking Himalayan glaciers raise risks of glacial lake outburst floods, landslides and altered monsoon B. It has no glaciers C. It emits the most gases D. It lacks mountains Answer: A. The article lists glacier shrinkage, GLOFs, landslides and monsoon change as risks. (Key point: Nepal's vulnerability) ## Related in Communication English - [Research article on transportation and tourism](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Aresearch-article-transportation-tourism-nepal) — Communication English, chapter 10 - [Research article on air pollution in Kathmandu](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Aresearch-article-air-pollution-kathmandu) — Communication English, chapter 10, asked 3× - [Research article on noise pollution](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Aresearch-article-noise-pollution-urban-nepal) — Communication English, chapter 10, asked 2× - [Research article on engineers in nation-building](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Aresearch-article-engineers-nation-building) — Communication English, chapter 10 - [Research article on power-point presentation](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Aresearch-article-powerpoint-technical-communication) — Communication English, chapter 10 - [Research article on IT in Nepal](https://www.bctengineer.com/question.md?key=semester_5%2Fcommunication_english%3Aresearch-article-it-development-nepal) — Communication English, chapter 10 ## Related in other subjects - [Global warming: causes, consequences, remedies](https://www.bctengineer.com/question.md?key=semester_2%2Fengineering_chemistry%3Aglobal-warming) — Engineering Chemistry, chapter 3, asked 2× - [Global warming and greenhouse gases](https://www.bctengineer.com/question.md?key=semester_7%2Fenergy_environment_and_society%3Aglobal-warming-ghg-climate) — Energy Environment and Society, chapter 4 - [Global warming: meaning, causes, consequences](https://www.bctengineer.com/question.md?key=semester_2%2Fengineering_chemistry%3Aglobal-warming-causes-consequences) — Engineering Chemistry, chapter 3 - [Short note: Global warming](https://www.bctengineer.com/question.md?key=semester_2%2Fengineering_chemistry%3Aglobal-warming-note) — Engineering Chemistry, chapter 3
