Greenhouse gases and global warming
Carbon dioxide (CO2) and other greenhouse gases act like a blanket, absorbing IR radiation and preventing it from escaping into outer space. The net effect is the gradual heating of Earth's atmosphere and surface, a process known as global warming.

Define greenhouse effect and global warming?
Greenhouse Effect:
The greenhouse effect is a natural process that warms the Earth's surface. It occurs when the sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. Greenhouse gases such as water vapor, carbon dioxide, methane, and nitrous oxide trap heat in the Earth's atmosphere, leading to a warming effect.
Global Warming:
Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the burning of fossil fuels and deforestation. These activities increase the concentration of greenhouse gases in the atmosphere, enhancing the greenhouse effect and causing the planet to warm.
Relationship between Greenhouse Effect and Global Warming:
The greenhouse effect is a natural phenomenon that keeps the Earth's surface warm enough to support life. However, human activities have intensified this effect by increasing the concentration of greenhouse gases in the atmosphere, leading to global warming. The enhanced greenhouse effect is causing temperatures to rise at an unprecedented rate, resulting in various environmental impacts such as melting ice caps, rising sea levels, and extreme weather events.
Impacts of Global Warming:
Global warming has far-reaching consequences for the planet and its inhabitants. It can lead to more frequent and severe heatwaves, droughts, wildfires, and hurricanes. Rising sea levels threaten coastal communities, while shifts in climate patterns can disrupt ecosystems and agriculture. Additionally, global warming can exacerbate health issues such as respiratory problems and the spread of infectious diseases.
In conclusion, the greenhouse effect is a natural process that becomes problematic when intensified by human activities, leading to global warming. Understanding these concepts is crucial in addressing climate change and implementing strategies to mitigate its effects.
