While the consensus warns of gloom and doom, the WSJ points out that warming has its positive aspects as well. For example, Trees seem to be responding well to increased CO2. See: Forests in the Eastern United States are growing faster than they have in the past 225 years
The 1970’s worry of the “population bomb” may very well have been subdued by CO2 helping crop yields. WUWT readers may be familiar with Indur Goklany, a regular WUWT contributor. He figures significantly in this WSJ article.

It seems the U.N. IPCC only tabulates the benefits of climate change when they are outweighed by the costs.
By ANNE JOLIS
Could global warming actually be good for humanity? Certainly not, at least if we’re to believe the endless warnings of floods, droughts, and pestilences to which we are told climate change will inevitably give rise. But a closer look at the science tells a more complex story than unmitigated disaster. It also tell us something about the extent to which science has been manipulated to fit the preconceptions of warming alarmists.
According to a 2004 paper by British geographer and climatologist Nigel Arnell, global warming would likely reduce the world’s total number of people living in “water-stressed watersheds”—that is, areas with less than 1,000 cubic meters of water resources per capita, per year—even though many regions would see increased water shortages. Using multiple models, Mr. Arnell predicted that if temperatures rise, between 867 million and 4.5 billion people around the world could see increased “water stress” by 2085. But Mr. Arnell also found that “water stress” could decrease for between 1.7 billion and 6 billion people. Taking the average of the two ranges, that means that with global warming, nearly 2.7 billion people could see greater water shortages—but 3.85 billion could see fewer of them.
Mr. Arnell’s paper, funded by the U.K. government, was duly cited in the U.N. Intergovernmental Panel on Climate Change’s supposedly authoritative 2007 assessment report. But the IPCC uses Mr. Arnell’s research to give the opposite impression, by a form of single-entry book-keeping. While it dutifully tallies the numbers of people he predicts will be left with less water access, it largely ignores the greater number likely to see more water courtesy of climate change.
The IPCC’s much-shorter “Summary for Policy Makers” is even more one-sided. It is riddled with warnings of warming-induced drought and—while acknowledging that a hotter Earth would bring “increased water availability” in some areas—warns that rising temperatures would leave “hundreds of millions of people exposed to increased water stress.” Nowhere does it specify that even more people would probably have more water supplies.
The IPCC also neglects to mention Mr. Arnell’s baseline forecasts—that is, the number of people expected to experience greater “water stress” simply due to factors like population growth and resource use, regardless of what happens with temperatures. This leaves readers with the misleading impression that all, or nearly all, of the IPCC’s predicted “water stress” increases are attributable to climate change.
These omissions were no accident. In 2006, prior to the release of the IPCC’s report and the all-important policy makers’ summary, Indur Goklany—at the time with the U.S. Department of the Interior—alerted the summary’s authors that it was “disingenuous” to report on a warmer world’s newly “water-stressed” without mentioning that “as many, if not more, may no longer be water stressed (if Arnell’s analyses are to be trusted).” Mr. Goklany’s advice was dismissed.
