What is Climate Change?

Back

Climate Change refers to significant changes in global temperatures and weather patterns over time. While climate change is a natural phenomenon, human activities, especially the burning of fossil fuels, have accelerated these changes.

What are Greenhouse Gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat. They include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.

Front

What is the Greenhouse Effect?

Back

The Greenhouse Effect is the process by which greenhouse gases absorb and emit infrared radiation, warming the Earth's surface.

Front

What is the primary source of methane (CH4) emissions?

Back

Agriculture is the primary source of methane emissions, particularly from livestock and rice production.

Front

What percentage of U.S. carbon dioxide emissions comes from non-fossil fuel combustion?

Back

6% of U.S. carbon dioxide emissions come from non-fossil fuel combustion.

Front

How do increased CO2 levels affect ocean carbonate availability?

Back

Increased CO2 levels decrease the availability of carbonate in the ocean, which is essential for marine life.

Front

What type of radiation do greenhouse gases allow to enter the Earth's atmosphere?

Back

Greenhouse gases allow shortwave radiation to enter the Earth's atmosphere.

Front

What is the role of carbon sinks?

Back

Carbon sinks are natural systems that absorb more carbon dioxide than they release, helping to mitigate climate change. Examples include forests, oceans, and soil.

Front

What is the impact of deforestation on climate change?

Back

Deforestation contributes to climate change by reducing the number of trees that can absorb CO2, thus increasing the concentration of greenhouse gases in the atmosphere.

Front

What is global warming?

Back

Global warming is the long-term heating of Earth’s climate system due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels.
