1. The Earth's temperature has increased by about 1 degree Celsius (1.8 degrees Fahrenheit) since the late 19th century.
2. The main cause of global warming is the release of greenhouse gases into the atmosphere.
3. Greenhouse gases trap heat from the sun's rays, causing the planet to warm.
4. The burning of fossil fuels is the largest source of greenhouse gas emissions.
5. Deforestation and other land-use changes also contribute to global warming.
6. Global warming is having a number of negative impacts on the planet, including:
* Rising sea levels
* More extreme weather events
* Changes in plant and animal life
* Melting of glaciers and ice caps
7. Global warming is a serious threat to the planet and its inhabitants.
8. We need to take action to reduce greenhouse gas emissions and mitigate the effects of global warming.
**The Earth's Changing Climate**
The Earth's climate has been changing for billions of years. However, the rate of change has accelerated in recent decades, and the main cause is human activity. The burning of fossil fuels, deforestation, and other land-use changes have released large amounts of greenhouse gases into the atmosphere. These gases trap heat from the sun's rays, causing the planet to warm.
**The Effects of Global Warming**
Global warming is having a number of negative impacts on the planet, including:
* Rising sea levels: As the Earth's temperature increases, the oceans expand and glaciers and ice caps melt. This is causing sea levels to rise, which is threatening coastal communities and infrastructure.
* More extreme weather events: Global warming is also leading to more extreme weather events, such as hurricanes, floods, and droughts. These events can cause widespread damage and loss of life.
* Changes in plant and animal life: Global warming is also affecting plant and animal life. Some species are moving to new areas, while others are becoming extinct.
* Melting of glaciers and ice caps: Global warming is causing glaciers and ice caps to melt. This is reducing the amount of fresh water available and is also contributing to sea level rise.
**What Can We Do?**
Global warming is a serious threat to the planet and its inhabitants. However, we can still take action to reduce greenhouse gas emissions and mitigate the effects of global warming. Some of the things we can do include:
* Reducing our reliance on fossil fuels
* Investing in renewable energy sources
* Improving energy efficiency
* Protecting forests
* Changing our agricultural practices
By taking action to reduce greenhouse gas emissions, we can help to protect the planet and its inhabitants from the worst effects of global warming.
