Global Warming
Global warming refers to the long-term increase in Earths average surface temperature due to the accumulation of greenhouse gases in the atmosphere. These gases, primarily carbon dioxide, methane, and nitrous oxide, trap heat from the sun and prevent it from escaping back into space, creating a natural greenhouse effect. However, human activities, such as burning fossil fuels, deforestation, and industrial processes, have significantly increased the concentration of these greenhouse gases, intensifying the greenhouse effect and causing the planet to warm at an alarming rate. Global warming is a critical issue with far-reaching consequences, including rising sea levels, more frequent and severe weather events, and disruptions to ecosystems and human societies.
Ans: The greenhouse effect is a natural process where certain gases in Earths atmosphere, such as carbon dioxide and methane, trap heat from the sun, preventing it from escaping into space, which helps maintain a habitable temperature on our planet.
Ans: Many factors, such as deforestation, burning fossil fuels, industrial processes, agricultural practices, land use changes, and waste management, contribute to global warming.
Ans: The effects of global warming include rising global temperatures, melting polar ice and glaciers, sea level rise, more frequent and severe extreme weather events (such as hurricanes and droughts), ocean acidification, biodiversity loss, health impacts, and potential food and water scarcity.
Ans: A little goes a long way. Here’s how you can fight against global warming on an individual level:
- Use public transportation, carpool, or adopt fuel-efficient and low-emission vehicles.
- Control water usage. Close the tap while brushing your teeth, which one in three Americans fail to do, according to a study by YouGov® .
- The R Mantra: Reduce, reuse, and recycle to minimise waste.
- Decrease your carbon footprint by planting trees.
