在下麵提問題。下麵說1% CO2 emission 來自自然現象。Chat GPT說 95%。聽誰的?
媒體想討論這種事，其實就直接讓數據說話就好。我是記得看到過火山爆發和人為造成emission的比較。我keep an open mind. 希望聽到NPR討論數據。
（發現這ChatGPT 還是很2.所有2都變成了問號。我手工改了。）
========================================================
Carbon dioxide (CO2) emissions are a combination of both natural and human-made sources, with human activities playing a significant role in the increase of atmospheric CO2. Here's a breakdown:
-
Natural Sources: About 95% of CO2 emissions come from natural sources, including processes like:
- Respiration of plants, animals, and microorganisms
- Decomposition of organic matter
- Volcanic eruptions
- Ocean release
-
Human-made Sources: The remaining 5% of CO2 emissions are from human activities, but these are a major concern due to their contribution to climate change. These activities include:
- The burning of fossil fuels (coal, oil, natural gas) for energy production, transportation, and industry
- Deforestation and land-use changes, which reduce the Earth's ability to absorb CO2
While natural processes produce much larger amounts of CO2, human activities have significantly increased atmospheric CO2 levels since the Industrial Revolution. This has led to a marked increase in the greenhouse effect, contributing to global warming and climate change.
