RE:RE:RE:RE:NASA and climate changeYour reading comprehension leaves a lot to be desired. From your own article:
While water vapor may be the most dominant greenhouse gas by mass and volume, it certainly is not the primary culprit responsible for global warming. Rather it is part of an amplifying effect. As other greenhouse gases such as CO2, warm the atmosphere, the air is able to hold more water vapor. The water vapor traps more heat and further warms the atmosphere. Human activities have increased CO2 output, and responsible human activities can reduce its production. Unlike water vapor that returns to Earth as precipitation within one week of entering the atmosphere, CO2 stays in the atmosphere between 50-200 years. Therefore, the best way to control global warming is to reduce CO2 emissions.
The GHG effect of water creates the natural balance. Man-made CO2 tips that balance.
