Greenhouse Gases: Causes of Global Warming

In summary, greenhouse gases are gases that allow infrared radiation to enter the stratosphere, but inhibit its passage out, resulting in a build-up of radiation and heat. This contributes to global warming and is a complex issue that can be better understood through studying environmental geology and chemistry. Some helpful resources include links on the nature of greenhouse gases and their role in climate change.

Do anyone know anything on the green house gases? How are they causing global warming?

A gas is 'defined' as a greenhouse gas if it allows the passive passage of Infra-red radiation through the atmosphere, into the stratosphere, but, also inhibits the passage of IR radiation out of the atmosphere, hence creating a build-up of radiation, and therefore heat in the stratosphere, contributing to what is now known as Global-Warming.

Its a complicated issue to form an analogy for,
if you still need help I recommend reading any recent textbook on Environmental Geology, and on Environmental Chemistry.

Greenhouse gases are just gases that absorb light. Think of it like wearing a black shirt when a spotlight is pointed directly at you. Your black shirt emits heat in all directions, but you still warm up faster than if you were wearing a white shirt.
 

1. What are greenhouse gases and how do they contribute to global warming?

Greenhouse gases are gases in the Earth's atmosphere that trap heat and contribute to the warming of the planet. This is known as the greenhouse effect. The most common greenhouse gases are carbon dioxide, methane, and water vapor. These gases act like a blanket, trapping heat that would normally escape into space and causing the Earth's temperature to rise.

2. What are the main sources of greenhouse gas emissions?

The main sources of greenhouse gas emissions are human activities, such as burning fossil fuels (coal, oil, and gas), deforestation, and agriculture. These activities release large amounts of carbon dioxide and methane into the atmosphere, contributing to the increase in greenhouse gases and global warming.

3. How do scientists measure the levels of greenhouse gases in the atmosphere?

Scientists use a variety of methods to measure the levels of greenhouse gases in the atmosphere. These include taking direct measurements from air samples, using satellites to track changes in atmospheric composition, and studying ice cores and tree rings to understand past levels of greenhouse gases.

4. Can we reduce greenhouse gas emissions and slow down global warming?

Yes, we can reduce greenhouse gas emissions by making changes to our daily habits and using more renewable sources of energy. This includes using public transportation or biking instead of driving, using energy-efficient appliances and light bulbs, and supporting policies that promote clean energy. By reducing greenhouse gas emissions, we can slow down the rate of global warming and mitigate its effects.

5. What are the potential consequences of continued global warming?

The consequences of continued global warming include rising sea levels, more frequent and severe natural disasters, changes in weather patterns, and loss of biodiversity. These effects can have a significant impact on human health, economies, and ecosystems. It is crucial that we take action to reduce greenhouse gas emissions and prevent further warming of the planet.
