The topic I wrote is about global warming because we are in the same world, we must love the world and the environment. And I want to know how to alleviate the problem of global warming. But at the moment, I feel that covid is changing the world.

Global climate change is caused by the emission of a large number of greenhouse gases by the burning of fossil fuels. Extreme climate effects under the background of various global warming are frequently staged around the world, such as snowstorms, hurricanes, floods, droughts. Global warming also causes glacier collapse and melting, sea level rise, grain production, species extinction… Before the irreversible global warming catastrophe, we can only effectively curb the global warming trend through a combination of energy conservation and emission reduction, abandoning fossil fuels, switching to renewable energy, energy conservation, energy efficiency improvement, emission reduction of greenhouse gases, and the protection of forests. Climate change affects a wide range of areas, including national defense, human health, international finance and so on. Scientists predict that by 2050, freshwater supplies in most parts of Asia — including Central and South Asia, East and Southeast Asia — will be strained, especially in some major river basins. Flood risk will increase significantly in coastal areas, especially in densely populated areas of South, East and Southeast Asia. In the context of global climate change, along with industrialization, urbanization and rapid economic development, the pressure on natural resources and the environment in Asia will further increase. In addition, the impact of climate change on human health is likely to be manifested in diarrhea caused by floods and droughts, with significantly increased morbidity and mortality.
