用英语写一篇关于全球变暖的文章，介绍其原因、影响和可能的解决方案。
Global warming is the gradual increase of the Earth's average surface temperature, primarily caused by human activities such as burning fossil fuels and deforestation. As a result, the amount of greenhouse gases such as carbon dioxide and methane in the atmosphere has increased, leading to a variety of negative impacts.

The effects of global warming are widespread and significant. Rising sea levels threaten coastal cities and islands, while extreme weather events such as hurricanes, droughts, and heatwaves become more severe and frequent. Animals and plants are forced to adapt or face extinction, and agricultural productivity is affected by changing climate patterns.

To combat global warming, individuals can make personal changes such as reducing their carbon footprint through energy-efficient practices and transportation options. Governments can promote renewable energy sources and incentivize sustainable practices in industries such as agriculture and transportation. International agreements such as the Paris Agreement aim to limit global temperature increases to a manageable level, but widespread cooperation and action will be necessary to achieve this goal.

In conclusion, global warming is a critical issue with serious impacts on the environment, economies, and societies around the world. Action must be taken at all levels to reduce greenhouse gas emissions and mitigate the effects of rising temperatures.
