What is climate change?
Explanation: The correct answer is B) Long-term alteration of temperature and weather patterns. Climate change refers to the long-term alteration of temperature and weather patterns over a significant period, typically decades to centuries. It is primarily driven by human activities, such as the burning of fossil fuels and deforestation, which release greenhouse gases into the atmosphere and disrupt the Earth's natural climate balance.
Which of the following is a greenhouse gas?
Explanation: The correct answer is B) Carbon dioxide (CO2). Carbon dioxide is a greenhouse gas that contributes to the greenhouse effect, trapping heat in the Earth's atmosphere. Other greenhouse gases include methane (CH4), nitrous oxide (N2O), and fluorinated gases. These gases enhance the natural greenhouse effect and are responsible for the observed warming of the planet.
What is the primary cause of recent climate change?
Explanation: The correct answer is C) Human activities. While natural climate variability and factors like solar activity and volcanic eruptions can influence climate patterns, the primary cause of recent climate change is human activities. The burning of fossil fuels, deforestation, industrial processes, and agricultural practices have significantly increased the concentration of greenhouse gases in the atmosphere, leading to an enhanced greenhouse effect and subsequent global warming.
What are the impacts of climate change?
Explanation: The correct answer is C) Rising sea levels. Climate change has numerous impacts, including rising sea levels due to the thermal expansion of warming oceans and the melting of glaciers and ice caps. Other impacts include more frequent and severe heatwaves, changes in precipitation patterns, increased frequency of extreme weather events, disruption of ecosystems and biodiversity loss, and negative impacts on agriculture, water resources, and human health.
What is the Paris Agreement?
Explanation: The correct answer is A) An international treaty to mitigate climate change. The Paris Agreement is an international treaty adopted in 2015 by nearly all nations to combat climate change. It aims to limit global warming well below 2 degrees Celsius above pre-industrial levels and pursue efforts to limit the temperature increase to 1.5 degrees Celsius. The agreement establishes targets for greenhouse gas emissions reduction, encourages climate finance, promotes technology transfer, and emphasizes international cooperation in addressing climate change.
