在下面提问题。下面说1% CO2 emission 来自自然现象。Chat GPT说 95%。听谁的?
媒体想讨论这种事，其实就直接让数据说话就好。我是记得看到过火山爆发和人为造成emission的比较。我keep an open mind. 希望听到NPR讨论数据。
（发现这ChatGPT 还是很2.所有2都变成了问号。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.
