Actually the UV levels have dropped by about 50%.
Soft and hard X-rays up to a factor of 1/10,000.
Ken: Isn't water vapor a greenhouse gas?
Combustion of gasoline: C8H18 + 12.5 O2 --> 8 CO2 + 9 H2O
(Yes, with incomplete combustion and other additives, the resultants are more complex.)
So you get 9 parts water and 8 parts CO2. Now add all the evaporation from irrigation, water use in heat exchangers and so on, you can easily see that people are adding more water to the atmosphere than CO2.
What about heat radiated from chemical and mechanical processes.
Now, what about that failure of the AGW models to predict the current cooling trend?
This is what brought me here in the first place.
Google ["Cubic Kilometers" "Fossil water" Irrigation]
You will see the HUGE amount of extra water vapor being put into the atmosphere by irrigation - and by definition all the irrigation is in ARID areas. So there is suddenly water vapor where once there was not and it makes the arid areas warmer especially at night.
And of course HYDRO-carbons when burnt are turned into H2O and CO2.
Water vapor provides far more radiative forcing than carbon dioxide AND even the AGW proponents know this as without it their AGW hypothesis is falisified.
But the IPCC only includes it in AR4 as a _feedback_
I'm wondering where you get that impression? Are you quoting someone? Have you actually delved into AR4? (I don't say 'read' because that's asking way too much. The damned thing is a high-level kloodge and about as much fun as a root canal.)
Page 182: "2.5.6 Tropospheric Water Vapour from Anthropogenic Sources
Anthropogenic use of water is less than 1% of natural sources
of water vapour and about 70% of the use of water for human
activity is from irrigation (Döll, 2002). Several regional studies
have indicated an impact of irrigation on temperature, humidity
The feedbacks section doesn't start until about Page 479.
The Earth's surface is 70% water, and the air over the ocean has 100% relative humidity. Over land, water from irrigation mixes with colder air and any excess water eventually drops out as rain. Wet (humid) air rises, radiates heat to space, and again the water comes out as rain. As the fabulous IPCC says, irrigation causes only about 1% of the H²O in the atmosphere. They might lie to you, but I won't.
