Climate Change Q&As

What is the leading cause of climate change?
Answer: The leading cause of climate change is human activities such as burning fossil fuels, deforestation, and industrial processes that release greenhouse gases into the atmosphere.

Which gas is the most significant contributor to the greenhouse effect?
Answer: Carbon dioxide (CO2) is the most significant contributor to the greenhouse effect.

How do human activities contribute to climate change?
Answer: Human activities contribute to climate change by increasing the concentration of greenhouse gases in the atmosphere, which traps heat and causes the planet to warm. This can happen through activities such as burning fossil fuels, deforestation, and industrial processes.

What is the global temperature increase that scientists consider dangerous?
Answer: Scientists consider a global temperature increase of more than 2 degrees Celsius above pre-industrial levels to be dangerous.

How does the warmer climate affect sea levels?
Answer: Warmer temperatures cause sea levels to rise as the polar ice caps melt and the water in the oceans expands.

How does climate change affect biodiversity?
Answer: Climate change can affect biodiversity by altering the distribution of species and changing the timing of seasonal events such as migration and reproduction. This can lead to the extinction of some species and the decline of others.

What are the main ways to reduce emissions of greenhouse gases?
Answer: The main ways to reduce emissions of greenhouse gases include shifting to renewable energy sources, increasing energy efficiency, reducing deforestation and land-use change, and implementing carbon pricing mechanisms.

What are the implications of climate change on human health?
Answer: Climate change can have negative impacts on human health by increasing the frequency and severity of extreme weather events, spreading disease, and affecting air and water quality.

How does climate change affect agriculture?
Answer: Climate change can affect agriculture by altering the timing and amount of precipitation, changing the length of growing seasons, and increasing the frequency of extreme weather events such as droughts and floods.

What is the Paris Agreement and what is its goal?
Answer: The Paris Agreement is an international treaty that was adopted in 2015 to limit the global temperature increase to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the increase to 1.5 degrees Celsius. Its goal is to mitigate the effects of climate change and to adapt to its impacts.
