[Green Circle Talks About Crossing the Border] Global warming is mainly due to the extensive use of

Global warming is mainly due to the release of greenhouse gases, especially carbon dioxide and methane, from the extensive use of fossil fuels. As industrialization accelerates and the global population grows, the demand for energy continues to rise, leading to the extraction and use of large quantities of coal, oil and natural gas. The combustion of these fossil fuels releases large amounts of carbon dioxide, which accelerates the development of the global greenhouse effect, leading to a continuous rise in global temperatures.

Over the past century, the massive use of fossil energy sources such as oil, coal and natural gas has led to a dramatic increase in the concentration of greenhouse gases (GHGs) in the Earth's atmosphere. Through observation and data analysis, scientists have found that the increase in these greenhouse gases has directly led to a rise in the Earth's temperature, which in turn has triggered a series of climate change problems such as extreme weather events, glacier melting, and sea level rise.

In addition to the use of fossil fuels, deforestation and land reclamation is one of the major causes of global warming. Forests are one of the largest carbon sinks on the planet, but large amounts of forests have been cut down and burned, resulting in the release of large amounts of carbon dioxide into the atmosphere. At the same time, land reclamation and urbanization also reduce vegetation cover, making the land lose its carbon sequestration function, thus accelerating the accumulation of greenhouse gases.

In order to cope with the challenges posed by global warming, governments and the international community have begun to take active actions. The Paris Agreement, as an important global agreement to address climate change, puts forward global greenhouse gas emission reduction targets, and countries have pledged to reduce greenhouse gas emissions, accelerate the development and application of clean energy, and promote the development of a low-carbon economy.

In addition, people should also start from their daily lives to save energy and reduce emissions, reduce their reliance on fossil energy, promote green transportation and low-carbon lifestyles, and make a concerted effort to address the global challenge of global warming. We hope that in the future, human beings will treasure the earth's resources more and protect our common home.
