Why global cooling is more likely and more dangerous than global warming...

In a warmer world, less energy is needed for heating and transportation, resulting in less air, land, and water pollution. Snow and ice that seriously hamper movement and increase the costs of land and water shipping are reduced. Roads, bridges, and other infrastructure maintenance costs drop, as there would be less freeze/thaw and ice damage. Clothing expenses obviously reduce in a warmer world, and construction costs plummet as less insulation is required in all buildings.
The benefits of warming are especially prominent in agriculture. Longer frost-free periods will extend growing seasons as well as the extent of agriculture in middle- and high-latitude regions. More and greater varieties of food are then possible in areas that are currently agriculturally marginal.
Contrary to the assertions of the United Nations Intergovernmental Panel on Climate Change (IPCC), a warmer world is a wetter world with less, not more, droughts. This is because evaporation increases with warming, putting more moisture into the atmosphere.

The experience of India, which has prospered while warming over the past 50 years, demonstrates how well humans, even those living in hot climates, can adapt to warming. But cooling is a killer, and — scientists are increasingly telling us — a more probable event as well.
It has been found that the Earth is warmer when the Sun is more active as indicated by sunspot count. Our planet is cooler when there are fewer sunspots. The current 11-year sunspot cycle, Cycle 24, is already showing less spots than predicted, and expectations are for lower numbers still in Cycle 25, expected to start in about ten years. Not surprisingly, global temperatures have leveled and show signs of declining. By the mid- to late 2020s, conditions comparable to the LIA are a distinct possibility. Beginning to plan for adaptation to such a cool period should be a priority for governments. Besides, if you plan for cooling and it warms, adaptation is much easier than if you plan for warming and it cools.
