A decrease of IR radiation from greenhouse gases ? OMG !
The AERI data record demonstrates that the downwelling infrared radiance is decreasing over this 14-yr period in the winter, summer, and autumn seasons but it is increasing in the spring; these trends are statistically significant and are primarily due to long-term change in the cloudiness above the site.
The global climate models AND 'the agenda' depend on the positive feed back chain that CO2 warms the planet, increases water evaporation, which in turn warms the planet more because H2O is also a “greenhouse” gas. The models also assume that clouds, on balance, also warm the planet, so more water vapor creating more clouds increases the feedback even more (the “Venus” scenario). This paper suggests that these positive feedbacks may not exist, and may even be negative !
