Conclusion: <blockquote>A reduction in relative humidity can occur even though water vapor pressure is increasing if temperature is warming sufficiently. Hence, decreases in relative humidity occur at stations experiencing the largest temperature increases in winter and spring as shown in Fig. 7. The strong correlation between increasing temperature and decreasing relative humidity trends agrees with that found by Vincent (Vincent et al; 2007)</blockquote>
Oooooops, so tell me again, how many GCMs have physics which match with the <b>observed reduction in relative humidity</b> with rise temperature and the consequent negative water vapour feedback?
