Astronomy - Ch. 9.1: Earth's Atmosphere (57 of 61) Is Atmospheric Water Vapor Increasing?

In this video I will explain the increase in CO2 can lead to increases in temperature which leads to increases in water evaporation which leads to increases in moisture in the atmosphere in the form of water vapor which will lead to a feed-back mechanism which sill lead to additional heating.

Next video in this series can be seen at:

I really enjoy your way of explaining these complex matters in bite-sized chunks. I keep sharing with people but most people seem a little too lazy to learn - although most do love pontificating without making any effort to know exactly what it is they are pontificating about. So thank you for your lessons which really deserve to have many thousands more views in my opinion.

The first couple times i went through this lecture series, i thought this water vapor, data was interesting.  Thinking about it more, this is a very important data set.

What i know about the water cycle:
All rain starts out as snow.
Nature converts water vapor to precipitation (rain) by binding to a particle of either dust or a biological substance by nucliation.  
Without dust there is no rain.
If man made dust (soot) is added to the air it will change the rain patterns and rain out moisture as soon a particle and water vapor  combines. 
Water vapor is lifted into the upper atmosphere by aerodynamic lift and heat.

What i know about dust, is that it can be transported from the Sahara desert to the Caribbean islands and florida on the trade winds. A very long distance. 

What i know about coal fired electric plants:
The combustion process is not complete, and soot (ash & black carbon or fly ash) is lofted into the air.

What i think i know about climate change:
The rate (slope) of global warming was higher prior to 1960 than it is today (post 1980).
Global warming flat lined from 1960 to 1980. The first world countries converted from coal to nuclear and oil fired power plants. And the remaining coal fired plants added collection systems to collect and mitigate fly ash.
China and India added many coal fired electric power generation plants in the 1990's without fly ash collection.  China is now adding collection.
Dirty snow melts even in the polar regions. And lasts in the environment for a long time.
CO2 and fly ash are emitted at the same time. Speculation on my part is that global warming should correlate with fly ash, just like CO2.

Outstanding. You should be lecturing at our universities...

The total column measurements of water vapor are up. Brown, S., S. Desai, S. Keihm, and C. Ruf (2007), Ocean water vapor and cloud burden trends derived from the topex microwave radiometer. Geoscience and Remote Sensing Symposium 2007, Barcelona, Spain, IGARSS 2007, IEEE International, 886-889.

I hope this series doesn't end in explaining the IPCC global temperature changes. They have been tampering with the data to make it "look like" the measured co2 values, which they cannot tamper with.

In the end, we likely will discover that tiny surface temperature rises increase evaporation and precipitation and water vapor convection, which forces a massive negative feedback to surface temps and a massive heat pump into the upper troposphere. One degree of extra heating probably results in degrees of subsequent cooling.

Just guessing..

Good morning Sir, Sir why you are not making further video on organic chemistry ?
