Humans have made the skies more moist
Study models rises in atmospheric water vapour.
Human activity is behind the rising levels of water vapour in the lower atmosphere over the past few decades, climatologists have concluded. The rises in humidity could affect patterns of extreme storms, they warn.

What are the enviros going to do now with their rolling, hydrogen powered , humidifiers that are the panacea for getting off oil? Tropics, here we come!!!!
Hello from South of France, near Marseille, and from the Alps Mountains, near the Mont-Blanc. In these places, since last november we can never see a real blue sky because of clouds made by too many planes. I've photographed these tracks and also the roads with less sun light. I'd like to talk more about that.
What are the assumptions of the computer model? Wouldn’t the computer model have to be programmed to increase humidity as the input for “man made gases� increased? The computer model logic is dependent on the premises of the programmer. It does not actually creates the conditions in nature. This study sounds like a self-fulfilling prophecy.
Well, now, if the abstract begins, "Water vapour is the most important contributor to the natural greenhouse effect," why the concern over carbon dioxide?! Also, as water vapour is effectively beyond human control, there is little we can do about its overall effect on the climate, I further believe.

First of all, the assumption that the global increase in temperature is man-made, has never adequately been proven. Mainly because we don't have accurate weather/temperature readings for more than about 100 years. Prior to that it was guess work and primitive equipment being used to tell the weather. Secondly, you have to assume that there really IS an increase in temperature, which also hasn't been adequately proven, for the very same reasons I stated above. While man may be contributing some increase in temperature in certain locales, there's never been any real science that says we are responsible for a global increase. Just a lot of assumptions and pseudo science with faulty data. How else can you explain temperature increases in one location, and 100 miles away the temperature shows a decrease over the same time frame? I'd try to prove the "facts" before I published shoddy papers.
Wow. An increase of 0.07 grams per kilogram worldwide! I find that incredible. Having sampled all the air globally, simultaneously and arrived at another meaningless metric. The moisture content (Specific Humidity) of air normally varies between a minimum of 4 and a maximum of about 40 grams per kilogram; perhaps on the same day in the same place. This is well-known in the practice of engineering airconditiong systems and in the design of cooling towers. There is no signal in the 0.07 g/kg. It does NOT prove anything other than folly. Back in the old days; when trying to turn noise into money, one would form a rock band. Nowadays it seems, one becomes a climatologist.
How can one be critical without getting offensive amidst all this folly.
