Carbon dioxide (CO?) emissions are a combination of both natural and human-made sources, with human activities playing a significant role in the increase of atmospheric CO?. Here's a breakdown:
Natural Sources: About 95% of CO? 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 CO? 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 CO?
While natural processes produce much larger amounts of CO?, human activities have significantly increased atmospheric CO? levels since the Industrial Revolution. This has led to a marked increase in the greenhouse effect, contributing to global warming and climate change.
=================================================
The majority of carbon monoxide (CO) emissions are from natural sources, but human activities significantly contribute as well. Here's a breakdown:
Natural Sources: About 70-90% of CO emissions come from natural sources, primarily from wildfires, vegetation decay, volcanic activity, and the oceans.
Human-made Sources: The remaining 10-30% of CO emissions come from anthropogenic (human-caused) sources, mainly from the burning of fossil fuels, including transportation (vehicles), industrial processes, and residential heating and cooking.
While natural sources dominate, human activity is responsible for a considerable portion of CO emissions, contributing to air pollution and impacting air quality, especially in urban areas.
人类观测气象历史满打满算180年，气候变迁周期何止百万年，就敢妄断变热变冷？
地球上有灯光的区域何其少，大量无人区的自然排放何其多，何其复杂，怎么敢在国际公约限制这限制那？
利益链条、阴谋论….吵吵几十年了，串谋也该败露了，共谋也该出来打脸了。
也没个科学家出来打打脸，阻止阻止，就由他们成天嚷嚷没用的事，扰乱人类社会真正应该关心的事情。冰期的成因都搞不清楚，基础理论有大量没搞明白的事，咋不搞了？记得70年代有个华裔地质学家还主持全球钻探计划，想搞明白地球的事，不了了之了？
（污染是另一回事，必须高标准，必须治理。）

损失咋办？损失你们担着，这不跟银行一个道理嘛！
得吃其他动物太残忍和不可思议，无他，只是环境的富裕程度差异带来的而已。在一个国家很富裕繁荣的时候，在意环保没啥错，而且也是自然会出现的现象。现在人们反问，间接说明了国家的实质变化
其实一直就是这样吧。只不过这些年太明显，或者我忽然开窍了？
就比如，新疆genocide 这么严重的事，解决了吗？不提了。新泽西满天汽车那么大的drones，忽然就都没了？也没说为什么有，为什么忽然没有了？
把你骗到倾家荡产没商量！
不是你突然开窍了
就是你开始注意媒体并开始思索了。
我早说了，说了很多年，不关乎左右，你可左可右，但不可以相信媒体，媒体是最邪恶的。不亲身经历，都会被媒体欺骗。 Trump说的最对的一句话就是，媒体是美国的敌人。
最后哈三笑说可以申请$750。川普和一龙和大批志愿者比拜哈更早去现场，去帮忙
那个猪妹报道了？
现在加州火灾，拜登倒是麻利的要给钱，所以不是FEMA 没钱，而是选择性给。

而且跟政治立场貌似还有很大关系
这是作为外行不懂的人的观察 呵呵
重点是我划的。
