3. Introduction Climate change refers to the long-term changes in the Earth's climate, including changes in temperature, precipitation, and weather patterns. These changes are primarily caused by human activities that release large amounts of greenhouse gases into the atmosphere, such as burning fossil fuels and deforestation.

4. Burning fossil fuels, such as coal, oil, and natural gas, releases greenhouse gases into the atmosphere. These gases trap heat, causing the planet to warm. Deforestation removes trees, which absorb carbon dioxide from the atmosphere. When trees are cut down, this carbon dioxide is released back into the atmosphere, contributing to climate change. Agriculture produces methane and nitrous oxide, which are also greenhouse gases. Industrial processes, such as cement production and metal smelting, also release greenhouse gases into the atmosphere. Cause Of Climate Change Human activities

5. Cause Of Climate Change Natural causes Volcanic eruptions can release large amounts of ash and sulfur dioxide into the atmosphere. These particles can reflect sunlight and cool the planet. Changes in solar activity can also affect Earth's climate. For example, during periods of low solar activity, the planet can cool.

6. Effects of climate change Rising sea level -earth’s temperature rise,glacier and ice caps melt, causing sea level rise. more extreme weather events- climate change is causing more extreme weather events. change in plants and animal life-climate change is causing changes in plant and animal life as species are forced to migrate to new area.

7. ocean acidification-as the ocean absorb more carbon dioxide from atmosphere, they become acidic melting glaciers and ice caps— are contributing to sea level rise and distrupting fresh water supply . mass extinctions-climate change is increasing the risk of mass extinctions as species are unable to adopt rapidly changing climate. Effects of climate change

8. Solutions reduce green house gas emission switch to renewable energy sources. improve energy efficiency reduce deforestation plant,trees

9. Build sea walls to protect coastal communities develop drought resistant crops improve early warning system for extreme weather Adapt to the impact of climate change

10. Policies and politics International climate agreement Paris agreement kyoto protocol united nations framework convention on climate change

11. National climate policies Carbon pricing renewable energy mandates energy efficiency standards Subnational climate policies regional green house has initiative california cap and trade program

12. Climate justice need for equitable solution for climate change disproportionate impact of climate change on marginalized communities Spread of misinformation about climate change role of special interest in blocking climate action Climate denialism

13. Recent Research Climate change is a rapidly evolving field of research, with new findings and insights emerging every day. Recent research has shown that the effects of climate change are becoming increasingly severe, with rising sea levels, more frequent and intense natural disasters, and devastating impacts on ecosystems and biodiversity. However, there is also reason for hope. Advances in renewable energy technologies, innovative policy solutions, and grassroots activism are all contributing to a growing movement for climate action.
