Climate Change

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, thus warming the planet.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that contribute to the greenhouse effect by absorbing infrared radiation. Key examples include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

How has atmospheric carbon dioxide changed since 1960?

Back

Atmospheric carbon dioxide levels have increased steadily since 1960, primarily due to human activities.

Front

What is the primary cause of rising sea levels?

Back

The primary cause of rising sea levels is the melting of land ice, such as glaciers and ice sheets, due to climate change.

Front

What are some effects of climate change?

Back

Effects of climate change include increased frequency of droughts, flooding, and the melting of polar ice caps.

Front

What is the role of deforestation in 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 the significance of the Paris Agreement?

Back

The Paris Agreement is an international treaty aimed at limiting global warming to below 2 degrees Celsius compared to pre-industrial levels, with efforts to limit the temperature increase to 1.5 degrees Celsius.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions in a specific place at a specific time, while climate refers to the long-term average of weather patterns over a significant period.

Front

What is melting sea ice, and why is it important?

Back

Melting sea ice refers to the reduction of ice cover in polar regions, which is important because it contributes to rising sea levels and disrupts marine ecosystems.
