Dramatic cuts in China’s air pollution drove surge in global warming

The rate at which the planet is warming has sped up since 2010, and now researchers say that China's efforts to clean up air pollution are inadvertently responsible for the majority of this extra warming

In the early 2000s, China had extremely poor air quality as a result of rapid industrialisation, leading to a public outcry in the run-up to the 2008 Beijing Olympics. In response, Chinese authorities fitted scrubbers to coal power plants to curb the dirtiest emissions and tightened rules governing vehicle exhausts, leading to a 75 per cent drop in sulphate emissions.

But there is a sting in the tail of this environmental success story. According to a new analysis, China’s dirty air had inadvertently been cooling the planet, and now that it is gone we are starting to see a greater warming effect.

没想到人肉吸尘器对世界做出了这么大的牺牲。

几十年前我在 Science 杂志上读到，亚洲人的水稻田是全球变暖的祸源，因为水稻田产生大量温室气体甲烷。我就奇怪了，亚洲人种了几千年的水稻、吃了几千年的大米也是罪过了。

又读到蚂蚁是全球变暖的罪魁祸首，因为蚂蚁不仅在数量上而且在总重量上都是一个惊人的数字。巨量的蚂蚁释放的蚁酸 (formic acid) 不仅造成酸雨，而且导致全球变暖。

他们还说牛是全球变暖的原因，因为牛胃中的食物在发酵过程中产生大量甲烷等温室气体。

2023年 Nutrients 杂志上一篇文章中，四位研究者忧心忡忡：全美市场上的一半牛肉被仅12% 的人口消耗掉了(https://doi.org/10.3390/nu15173795)。这可不好！而且吃这么多牛肉对全球变暖影响极大，应该多吃植物蛋白。

植物蛋白好啊。中国自古就有豆腐、面筋等植物蛋白食品：既营养又健康、味道也好。豆腐是用大豆做的。等等！环保人士抗议了，不可持续性生产方式生产大豆、以大豆为食物(来源) 对自然界造成威胁 (NATURE IS THREATENED BY UNSUSTAINABLE PRODUCTION AND CONSUMPTION OF SOY)。所以吃植物蛋白也有问题。https://earth.org/soybean-products-and- ... al-impact/

变暖教教徒们，你们说说看我们该吃啥？

生物圈里的碳都是循环的。从地层里面挖出来的碳才是问题。

1, 空气中的水是最强的温室效应分子。Water vapor (H2O) is the strongest greenhouse gas. https://www.ces.fau.edu/nasa/module-2/h ... -works.php

2, 当前大气中水蒸气的平均浓度是0.25%: Global mean water vapor is about 0.25% of the atmosphere by mass and also varies seasonally, in terms of contribution to atmospheric pressure between 2.62 hPa in July and 2.33 hPa in December. https://en.wikipedia.org/wiki/Water_vap ... 20December.

3, 当前大气中CO2的平均浓度大概是 427 ppm (0.0427%): The concentration of carbon dioxide (CO2) in the atmosphere reached 427 ppm (0.0427%) on a molar basis. https://en.wikipedia.org/wiki/Carbon_di ... %20century.

所以空气中的CO2浓度远低于水的浓度。

4, 温室效应主要是由水引起的。Calculation suggests that water vapor and clouds contribute 70% to 80%, and CO2 contributes 10% to 20% of the greenhouse effect. https://agupubs.onlinelibrary.wiley.com ... ensitivity.

最简单的例子，为什么干旱的沙漠昼夜温差那么大而海边的昼夜温差小？根本原因就是沙漠非常干旱空气中水分含量低，而海边空气中水分含量高。水分含量高低而不是CO2决定了昼夜温度变化幅度。

人类活动引起的气温波动与地球自身的气温周期性变化相比微不足道，说人类活动导致全球气温异常纯粹是胡扯，那些鼓吹人类活动导致气候异常的人太高估人类了。

Bill Bryson 在 "A Short History of Nearly Everything" 一书中写道：
Climate is the product of so many variables - rising and falling carbon dioxide levels, the shifts of continents, solar activity, the stately wobbles of the Milankovitch cycles - that it is as difficult to comprehend the events of the past as it is to predict those of the future. Much is simply beyond us. Take Antarctica. For at least twenty million years after it settled over the South Pole Antarctica remained covered in plants and free of ice. That simply shouldn't have been possible.

云层增加会降低温室效应。问题是人类活动好像不利于水的自然循环，因为大量的水直接通过管道排放掉了。具体影响需要认真建模测算一下。

二氧化硫？

二氧化硫？

While SO2 contributes to acid rain and is a major air pollutant, it does not trap heat in the atmosphere like greenhouse gases do.
