L 4.4: Climate Change

Front

What are sun cycles?

Back

Sun cycles refer to the fluctuations in the output of the sun, which can cause Earth's temperature to increase or decrease.

Front

What is La Nina?

Back

La Nina is a climate pattern that causes equatorial eastern Pacific Ocean temperatures to decrease, potentially leading to flooding or drought.

Front

What is El Nino?

Back

El Nino is a climate pattern that causes the tropical Pacific Ocean temperature to increase, resulting in some areas being cooler and wetter than normal and others being warmer and drier.

Front

What is the Kyoto Protocol?

Back

The Kyoto Protocol is an environmental agreement created in 1997 aimed at reducing greenhouse gas emissions globally.

Front

What has been the trend in CO2 levels in the atmosphere?

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily driven by human activities.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect and climate change.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm enough to support life.

Front

What role do oceans play in climate regulation?

Back

Oceans absorb carbon dioxide and heat, influencing global climate patterns and weather systems.

Front

What is global warming?

Back

Global warming is the long-term increase in Earth's average surface temperature due to human activities, particularly the burning of fossil fuels.
