As an atmospheric scientist, there is no debate about climate change. It is happening.,(reply>), @Robb Hays because your stupid, that’s why you laugh right?,(reply>), As someone who lives in an area that is subtropical, but was once covered in ice, I agree, the climate is changing.,(reply>), As someone who lives in the Alps at 1800m altitude it's obvious the climate is warming,(reply>), "There is no debate" is always a good start to bring your argument across.,(reply>), @ModernGameArmy absolute humidity is what would determine how much the bloody water would heat the earth not relative humidity. Relative humidity is used on weather reporting because it is quick cheap and easy to calculate and provides a fairly good idea of what the humidity is going to FEEL like and not how much water is in the air. As the name suggests, relative humidity is relative. It is a more or less present humidity in the air compared to maximum humidity possible for air at that temperature. And guess how the saturation point is created? With a soaked rag tied to the end of the thermometer. Absolute humidity measures amount of water per unit volume of air and as such is a much better measure of how much water is really present in the air.
