Introduction
Introduction
Probably the most worrying threat to our planet at the present time is global warming. Global warming is a major threat to the earth because it can cause serious problems.
Task
1) Definition
Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate.
2) Causes of Global Warming
- Greenhouse effect: One of the first things learned is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways.
- Sunspots: Increased solar activity changes the Earth's solar radiation levels, thereby causing short-term warming cycles. Surrounding sunspots are bright patches known as faculae. These patches give off greater than normal radiation, and they are more powerful than the darker, cooler patches. This means that the total average energy over a 30-day solar rotation increases.
- Water vapor is increasing in the atmosphere due to carbon dioxide-induced warming as indicated by NASA. Approximately two-thirds of the heat trapped by greenhouses gases is contained in water vapor, according to NASA. As the average temperature on the planet continues to rise, the amount of water vapor rises in turn.
- Burning of Fossil Fuels: According to the EPA, carbon dioxide is the most significant cause of global warming, and most carbon dioxide emissions result from the burning of fossil fuels. Each time a fossil fuel burns, carbon dioxide levels in the atmosphere increase. Carbon dioxide absorbs infrared energy emitted from the earth, preventing it from returning to space.
- Mining: Mining oil and coal allows methane, a greenhouse gas, to escape from the earth. Any time the soil is disturbed, stored gases make their way into the environment.
3) Effects of Gobal Warming
Glaciers are melting, sea levels are rising, cloud forests are dying, and wildlife is scrambling to keep pace. It's becoming clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. We call the result global warming, but it is causing a set of changes to the Earth's climate, or long-term weather patterns, that varies from place to place.
Global warming can potentially affect every aspect of life on Earth as outlined by the USC. Higher average temperatures will cause changes in plant and crop life, which can decrease worldwide food supplies. Warmer polar winters will result in melting sea ice, which will cause a rise in sea level. Warmer temperatures will also increase evaporation from large water bodies, which in turn will increase cloud formation and rainfall amounts.
Other potential Effects of Gobal Warming include more frequent hurricanes and higher rates of some diseases, such as malaria. The steady rise in the global population is going to make the underlying causes of global climate change worse, making things even more difficult for an increasingly large number of people.
3) Solutions of Global warming
We have the practical solutions at hand to dramatically reduce our carbon emissions, slow the pace of global warming, and pass on a healthier, safer world to future generations. Here's how we can accomplish it.

- Reduce Emissions
- Stop Deforestation
- Fight Misinformation
- Prepare for Impacts
- etc.
Conclusion
We can reduce global warming emissions and ensure communities have the resources they need to withstand the effects of climate change—but not without you. Your generous support helps develop science-based solutions for a healthy, safe, and sustainable future. We need to raise people's awareness of the environment to improve their lives.
