Greenhouse gases are important for the Earth's climate system because they trap heat in the atmosphere, which helps regulate the planet's temperature. This natural process keeps the Earth warm enough to support life. However, human activities have increased the levels of greenhouse gases, leading to global warming and climate change.
Climate change. It refers to long-term changes in temperature and typical weather patterns that affect the Earth's climate system. It is largely attributed to human activities, such as burning fossil fuels and deforestation, which release greenhouse gases into the atmosphere.
b. The climate system is complex and involves various interconnected components, such as temperature, greenhouse gas concentrations, ocean currents, and ice coverage. Different instruments are needed to measure these different aspects of the climate system accurately.
The Framework Convention on Climate Change was created by the United Nations to provide a framework for international cooperation to combat climate change. It aims to stabilize greenhouse gas concentrations in the atmosphere at a level that will prevent dangerous interference with the climate system.
The most important variable gases in Earth's atmosphere are carbon dioxide (CO2), methane (CH4), and water vapor (H2O). These gases play a significant role in the Earth's climate system, contributing to the greenhouse effect and influencing global temperatures. Monitoring their concentrations is crucial for understanding and predicting climate change.
Greenhouse gases are helpful because they keep the earth warm enough for life. They are essential.Too much greenhouse gases are unhelpful because they make the earth too hot. Global warming is causing climate change which may make the world very uncomfortable for our children and grandchildren.

Greenhouse gases are gases in the atmosphere that trap heat from the sun, causing the Earth's surface to warm. This warming effect is known as the greenhouse effect. The main greenhouse gases are carbon dioxide, methane, and water vapor. When these gases accumulate in the atmosphere, they enhance the natural greenhouse effect, leading to global warming and climate change.
Natural warming is not a direct part of the greenhouse effect, but it is influenced by it. The greenhouse effect refers to the process by which greenhouse gases in the atmosphere trap heat from the Earth's surface, leading to warming. Natural processes, such as volcanic eruptions and solar radiation variations, also contribute to Earth's climate, but the greenhouse effect primarily explains the current trend of anthropogenic climate change. Thus, while natural warming occurs, it interacts with the greenhouse effect in shaping the overall climate system.
The sun is a major factor affecting the world's climate as it provides the energy that drives Earth's climate system. However, other factors such as greenhouse gas concentrations, volcanic activity, and ocean currents also play significant roles in shaping the climate.
Momentum in the climate system refers to the tendency of Earth's climate to continue on its current trajectory due to the inertia of various factors like greenhouse gas concentrations and ocean heat storage. Changes in momentum can lead to long-lasting impacts on the climate system, making it challenging to reverse or mitigate certain climate-related effects.

Carbon dioxide can function as a greenhouse gas by trapping heat in the atmosphere, leading to increased global temperatures. This effect, known as the greenhouse effect, is an essential component of Earth's climate system.
The Framework Convention on Climate Change was created by the United Nations to provide a framework for international cooperation to combat climate change. It aims to stabilize greenhouse gas concentrations in the atmosphere at a level that will prevent dangerous interference with the climate system.
Water vapor and carbon dioxide are indeed significant greenhouse gases, contributing to the Earth's greenhouse effect and influencing the climate. Water vapor is the most abundant greenhouse gas, but carbon dioxide has a longer atmospheric lifetime and can have a more sustained impact on the climate system due to human activities such as burning fossil fuels.

Four theories that explain why Earth's climate has changed include the Milankovitch cycles, which focus on variations in Earth's orbit and axial tilt affecting solar radiation; plate tectonics, which alters ocean currents and atmospheric patterns over geological time; volcanic activity, which can release large amounts of greenhouse gases and ash, influencing temperature; and human-induced climate change, primarily driven by the burning of fossil fuels and deforestation, leading to increased greenhouse gas concentrations in the atmosphere. Each of these factors contributes to the complex and dynamic nature of Earth's climate system.
