Question

answer the following questions. 1. in your own words, what is climate change? 2. describe the greenhouse effect. 3. why should we be concerned with climate change?

Explanation:

1. Climate change refers to long - term shifts in global or regional climate patterns, including changes in temperature, precipitation, wind patterns, etc., often driven by human activities like burning fossil fuels and deforestation.
2. The greenhouse effect is a natural process. Certain gases in the Earth's atmosphere (greenhouse gases such as carbon dioxide, methane) trap heat from the sun, warming the planet. Human activities have enhanced this effect, leading to increased global temperatures.
3. We should be concerned about climate change because it can cause rising sea levels, more extreme weather events (such as heatwaves, floods, droughts), disrupt ecosystems, and threaten food and water security.

Answer:

1. Climate change is long - term alterations in climate patterns due to human and natural factors.
2. The greenhouse effect is the trapping of solar heat by atmospheric gases, with human actions intensifying it.
3. We should be concerned as it brings sea - level rise, extreme weather, ecosystem disruptions, and food - water security threats.
