Alarmists have been decrying the effects of global warming on Greenland for years, even though Greenland was greenest during the Medieval Warm Period, and Greenland’s Vikings, who flourished during that warm period, died out when cold temperatures returned, reducing them to starvation. (It was warmer in the year 1003 than 2003.) Now, the residents of Greenland, the world’s largest island, are once again profiting from global warming, reports the Washington Post:
“Rather than questioning global warming, many of this island’s 60,000 inhabitants seem to be racing to cash in. The tiny capital of Nuuk is bracing for record numbers of visitors this year; the retreating sea ice means a longer tourist season and more cruise ships . . . Hunters are boasting of more and bigger caribou, and the annual cod migration is starting earlier and lasting longer. In the far south, farmers are trying their hand at an exotic form of agriculture: growing vegetables. ‘Before, the growing season was too short for vegetables,’ . . .‘Now it is getting longer each year.’”
Since 2009, the Environmental Protection Agency has sought to regulate greenhouse gases like carbon dioxide (which we breathe out and plants consume) because they supposedly threaten public health in the United States by causing global warming. President Obama has backed a corporate welfare-filled global-warming bill that would increase electricity bills. Obama admitted to the San Francisco Chronicle in 2008 that under his “cap and trade” plan to address global warming, “electricity rates would necessarily skyrocket.”
But even if greenhouse gas emissions are the principal cause of global warming (as opposed to natural causes), it’s not clear why such warming would harm public health in a non-tropical country like America. After all, people in America’s warmer cities have lower mortality rates, and higher life expectancies, than people in its colder cities.
Warmer climates may be particularly helpful for racial minorities in Canada. Most non-white Canadians suffer from Vitamin D deficiency, putting them at risk of cancer, osteoporosis, and diabetes, according to the Toronto Globe and Mail. Lack of exposure to the sun is a big part of the problem. More than 50,000 people die every year in the United States every year as a result of inadequate sun exposure. While milk is Vitamin D enriched, many non-whites are lactose intolerant. Sunlight is the most potent source of Vitamin D. But in northern regions like Canada, sunlight alone does not provide enough Vitamin D for many people who work indoors. There, the sunlight is too feeble in winter and fall for people’s bodies to turn sunlight into Vitamin D. To get enough Vitamin D from the sun, people have to go outside a lot during spring and summer to offset the weak sunlight in fall and winter. But increasingly sedentary lifestyles and office jobs have reduced outdoor activity. And cold temperatures in spring discourage warmth-loving people from going outside, even when the light is strong enough to produce Vitamin D. Thus, cold climates can be bad for their health.
