What Is Climate Change? How climate change raises the risk of glacier and rock collapse Climate change means abrupt shifts in temperature and weather. Some of these shifts occur naturally, while others result from human activities such as burning fossil fuels like coal, oil and gas. Burning fossil fuels produces greenhouse emissions that act like a blanket wrapped around the Earth, trapping the sun's heat and raising temperatures. The main greenhouse gases, such as carbon dioxide and methane, cause climate change. Clearing land and deforestation can also release CO2. Agriculture, oil and gas are the primary sources of methane emissions. These are a few of the main sources of greenhouse gases. We face a huge challenge, but we have many solutions. Climate change can be reduced by eliminating CO2 from the atmosphere, which requires systemic changes. The United Nations Environment Programme estimates that countries must double their pledges under the Paris Agreement within the next dec...
What Strategies Did China Implement to Tackle Air Quality Issues? Introduction: Understanding China’s Air Quality Challenge Causes of Air Pollution in China China’s Turning Point: The Fight Against Smog Begins Major Government Policies and Plans Technological Innovations for Cleaner Air Renewable Energy and Industrial Transformation The Road Ahead — China’s Vision for a Cleaner Future Conclusion: The Road Ahead for a Cleaner China Introduction: Understanding China’s Air Quality Challenge China has been a central concern of the world conversation regarding air pollution for decades: while the country at one point housed some of the most polluted cities on the planet, rapid industrial growth with gross environmental damage became the prevailing scenario. Thick smog, toxic air, and health issues increasing in frequency painted a grim picture of uncontrolled progress. But in recent years, China has transformed from the "global pollution capital" to a model...
