Global warming refers to the long-term increase in Earth's average surface temperature due to human activities that release greenhouse gases into the atmosphere. These greenhouse gases, such as carbon dioxide and methane, trap heat from the sun, leading to a warming effect on the planet.
Here are some key points to understand about global warming:
1. Human Activities: Activities such as burning fossil fuels (like coal, oil, and gas), deforestation, and industrial processes contribute to the increase in greenhouse gases in the atmosphere.
2. Impact on Climate: Global warming leads to changes in climate patterns, causing more frequent and severe weather events such as heatwaves, droughts, hurricanes, and heavy rainfall.
3. Melting of Ice: The warming temperatures cause polar ice caps and glaciers to melt, leading to rising sea levels. This melting ice also affects habitats for various species, including polar bears and seals.
4. Ocean Acidification: The absorption of excess carbon dioxide by oceans leads to ocean acidification, which can harm marine life, including coral reefs and shellfish.
5. Mitigation Strategies: To address global warming, efforts such as reducing carbon emissions, transitioning to renewable energy sources, promoting energy efficiency, and adopting sustainable practices are crucial.
In summary, global warming is a significant environmental issue caused by human activities that increase greenhouse gases, resulting in a warming effect on the planet and impacting ecosystems and weather patterns worldwide. It is essential to take action to mitigate its effects and protect the Earth's climate for future generations.
