Causes of Climate Change: Climate change is primarily caused by human activity. Burning fossil fuels (such as oil, natural gas, and coal), deforestation, intensive agriculture, and greenhouse gas emissions are some of the main causes. These activities release large amounts of carbon dioxide (CO2) and other greenhouse gases into the atmosphere, which traps heat and causes global warming.
Greenhouse Effect: The greenhouse effect is a indian phone number list natural process that allows the Earth to retain some of the sun's heat. However, human activities have intensified this effect, leading to an increase in the average temperature on Earth. Greenhouse gases, such as CO2 and methane, trap heat in the atmosphere and cause global warming.
Climate Change Impacts: Climate change has a range of impacts around the world. These include rising sea levels due to thermal expansion and melting of the polar ice caps, extreme weather events such as droughts, floods and more intense storms, ocean acidification, changes in species migration patterns and threats to food security and access to clean water.
Positive feedback: Climate change can trigger positive feedback processes that amplify the effects of global warming. For example, melting ice in the Arctic reduces Earth's reflectivity (albedo), which in turn accelerates warming by absorbing more heat.
Mitigation and Adaptation: Climate change mitigation involves reducing greenhouse gas emissions through measures such as transitioning to renewable energy sources, energy efficiency and reforestation. Adaptation refers to adjusting to the impacts of climate change, such as building flood defences and implementing climate-resilient agricultural practices.
