A paper in discussion for Climate of the Past reconstructs summer relative humidity on the eastern Tibet plateau over the past 800 years and finds a sharp decrease beginning in the 1870’s. According to the authors,
We identified more moist conditions at the termination of the Medieval Warm Period, an oscillating air humidity around the mean during the Little Ice Age and a sudden decrease of relative humidity since the 1870s. We agree with the conclusions of Xu et al. (2012) who associate the humidity decline to the decrease of the thermal gradient between the tropical and north Indian Ocean, caused by the reduction of the land-ocean temperature difference. However, the reasons for the temperature contrast reduction are not sufficiently clarified. Lau et al. (2006) attributed the humidity reduction to the increase of greenhouse gas and aerosol emissions, while Duan et al. (2000) discovered a relationship to solar activity. The beginning of the humidity decline precedes the onset of Asia’s industrialization and therewith massive aerosol emissions. Thus, solar activity and an accompanied temperature increase seems more plausible to regulate the northern hemispheric temperatures and therewith the thermal land-ocean contrast.
These findings are of interest for at least two reasons:
1. They suggest the Northern Hemisphere temperature increase since the end of the Little Ice Age in ~1850 was driven by accumulated solar energy, not man-made greenhouse gases.
2. Climate models make the simplistic assumption that a warming climate will cause an increase in specific humidity while relative humidity remains constant. However, the reconstruction in this paper and observations from several other papers have shown this assumption to be false, falsifying this critical assumption of climate models. Instead of remaining constant, relative humidity has decreased to offset the increase in specific humidity with warming. This is as predicted by Miskolczi’s theory of a saturated greenhouse effect and implies that additional increases in greenhouse gases will not cause additional global warming.

Cheeseburgers Won’t Melt the Polar Ice Caps
The next targets of the climate change enforcers will be livestock and all Americans who eat meatBy JAYSON LUSKAug. 17, 2014 7:19 p.m. ET THE WALL STREET JOURNALThe documentary film “Cowspiracy,” released this week in select cities, builds on the growing cultural notion that the single greatest environmental threat to the planet is the hamburger you had for lunch the other day. As director Kip Andersen recently told the Source magazine: “A lot of us are waking up and realizing we can choose to either support all life on this planet or kill all life on this planet, simply by virtue of what we eat day in and day out. One way to eat takes life, while another spares as many lives (plant, animal and otherwise) as possible.”James McWilliams, vegan author of the 2013 book “The Politics of the Pasture,” argues that modern agricultural, and the cattle industry in particular, are part of a global food-supply system so damaging that the only moral solution is to give up eating meat entirely.
Each to his own, you might say. But these ideas are working their way into government policy proposals. For example, Angela Tagtow, a self-described “environmental nutritionist” formerly with the Minnesota Institute for Sustainable Agriculture, was recently tapped to head the U.S. Department of Agriculture’s effort to revise federal dietary guidelines. This is a sign that the new recommendations are likely to go beyond nutritional science to incorporate environmental considerations. Many observers believe that meat will be specifically targeted for scrutiny.Environmental nutritionists argue that the social and environmental costs of meat production—obesity, chronic disease, the production of green-house gases such as methane, etc.—are not reflected in prices at the grocery store or restaurant. “The big-ticket externalities are carbon generation and obesity,” New York Times columnist Mark Bittman recently wrote. He argues that beef prices don’t reflect these externalities and that “industrial food has manipulated cheap prices for excess profit at excess cost to everyone.”That the price of meat is too low might come as news to food consumers who, according to data from the Bureau of Labor Statistics, paid 14% higher prices for ground beef this June than they did in June 2013 and 29% more than two years ago. Recent droughts and high corn prices—due in part to Washington’s support for ethanol—are …
