当然，二氧化碳与温度的相关性并不能确定是大气成分的变化导致了气候变暖或变冷的趋势，还是它们本身造成的。
The correlation of carbon dioxide with temperature, of course, does not establish whether changes in atmospheric composition caused the warming and cooling trends or were caused by them.

但无论孰对孰错，这都是一个极富吸引力的想法：为什么不能利用光合作用用回收二氧化碳的方法来取代直接将其排放到大气中的做法呢？
Whoever turns out to be right, though, it is an intriguing idea: instead of releasing the carbon dioxide produced by burning fossil fuels into the atmosphere, why not recapture it by photosynthesis?
但是如果我们不能找到限制全球二氧化碳排放的方法，我们对海洋的改变就会超出它自我修复的能力，再也不能像现在这样支持海洋生物生存了。
But if we can't figure out a way to curb global carbon emissions, we may alter the oceans beyond their ability to heal themselves - at least in ways that will support Marine life as we know it.
二氧化碳在许多方面类似于氮气，但如果它与石灰水混合，它就使清澈的液体变成乳状液，而氮气不能，由此可以鉴别热氧化碳。
Carbon dioxide is like nitrogen in many ways, but if it is mixed with limewater, it causes the clear liquid to because milky, while nitrogen dose not. This is the test for carbon dioxide.
我们不能确定(难以避免的)气候变化的程度，因为我们讨论的是数百万年来仅见的大气二氧化碳含量。
We're uncertain about the magnitude of climate change, which is inevitable, because we're talking about reaching levels of carbon dioxide in the atmosphere not seen in millions of years.
作为回报，该州保健和环境部不能将任何有关温室气体排放的规定强加给该公司，而华盛顿方面对二氧化碳排放的限制却相当严厉。
In return, the Kansas Department of Health and Environment cannot impose any greenhouse-gas regulations that are tougher than those emerging from Washington. Suddenly, that seems a pretty high bar.
大气层不能吸收我们排放的所有的二氧化碳并且已经发出了危险警告。
The atmosphere can't absorb the amount of carbon we are putting into it, creating dangerous warming.
然而直到今天，还有许多人不能体会到植物贮藏二氧化碳从而使地球适合人类居住的重要功能。
Yet the importance of plants' ability to store carbon in making the planet habitable is still not widely appreciated.
这是由于大气不能完全支配在水平面上的二氧化碳浓度。
This is because the atmosphere does not have an iron grip on the carbon-dioxide level in surface waters.
二氧化碳浓度过高引起的平均温度变化，可能会因为实施第一种办法有所缓和，单纯减少太阳辐射量却并不能让气温恢复到以前的状况。 当地的温度仍旧会发生变化，比如受洋流，降雨量，土壤湿度和光合作用的影响。
While it is possible to imagine doing so in a way that cancels out the change in average temperature caused by an increase in carbon dioxide, such a reduction would not simply restore the status quo.
而另外一些却不能直接检测，比如从土壤中排放的一氧化二氮与从牲口身上排放的沼气。
Others, such as nitrous-oxide emissions fromsoils and methane emissions from animals, cannot.
然而，研究人员发现在30摄氏度这种清除过程并不能清除活性氧或阻止氧化损伤的发生。
However, at 30 degrees centigrade the researchers found that the cleanup processes cannot cope with ROS and oxidative damage occurs.
相反，TrES - 2b的大气层由气态钠、钾和三氧化钛这些可以吸收光线的化学物质组成，不过这也并不能为该行星极黑提供解释。
Instead, it has an atmosphere made up of chemicals such as vaporized sodium, potassium and gaseous titanium oxide, which absorb light, but that still does not explain the planet's extreme blackness.
但是由于那些“讨厌的”二氧化碳分子在大气中积累，使得有些热量不能散回到太空中去——这样就不可避免地使我们的地球变暖。
But some of that heat gets blocked by those pesky carbon dioxide molecules building up in the atmosphere-inexorably warming our planet.
然而除了在初期阶段之外，光吸收的数值并不能很好地反应氧化的程度。
However, the magnitude of the absorbance does not correlate well with the degree of oxidation EXCEPT in the early stages.
在这项研究中，研究者发现，服用阿司匹林和抗氧化剂等补充物不能预防有糖尿病和无症状的动脉疾病的患者的心脏病的发生。
In this study the researchers found that taking aspirin and antioxidant supplements did not prevent heart attacks among people with diabetes and asymptomatic arterial disease, even those at high risk.
与此相反，课题组的结论是，由二氧化碳过高引起的全球变暖“在很大程度上是不可逆转的，即使在停止排放的1000年之后也不能恢复正常。”
Instead, the team concluded, warming tied to higher CO2 "is largely irreversible for 1, 000 years after emissions stop."
我知道我们不能派特使与大规模流行的疾病进行谈判，不能与二氧化碳召开高峰会，也不能与全球金融危机断绝关系。
Now, I know we cannot send a special envoy to negotiate with a pandemic, or call a summit with carbon dioxide, or sever relations with the global financial crisis.
一项研究表明食用牛奶巧克力并不能增加血液中的抗氧化剂，这也许是因为牛奶阻碍了巧克力中的抗氧化剂的吸收。
One study found that eating milk chocolate did little to raise antioxidant levels in the blood, perhaps because milk interferes with the absorption of antioxidants from chocolate.
所以氧气并不能在空气中堆积很长时间，因为它被易氧化的石头吸收了。
The oxygen did not build up in the atmosphere for a long time, since it was absorbed by rocks that could be easily oxidized (rusted).
不能饮葡萄酒的人应该寻找其它含有多酚和抗氧化剂的食品。
People who can't drink wine should such look to other whole foods with polyphenols and antioxidants, like pomegranates and blueberries.
不能饮葡萄酒的人应该寻找其它含有多酚和抗氧化剂的食品。
People who can't drink wine should such look to other whole foods with polyphenols and antioxidants, like pomegranates and blueberries.
