Effects of global warming on human health

The EPA’s “endangerment finding” classified carbon dioxide as a pollutant and claimed that global warming will have adverse effects on human health. Real research says the opposite: cold is deadlier.  The scientific evidence shows that warming is good for health. This is discussed in detail in chapter 7 of Climate Change Reconsidered II: Biological Impacts published by the Heartland Institute. See links to the entire publication at:

Here are the key findings based on extensive review of the scientific literature:

• Warmer temperatures lead to a net decrease in temperature-related mortality, including deaths associated with cardiovascular disease, respiratory disease, and strokes. The evidence of this benefit comes from research conducted in every major country of the world.

• In the United States the average person who died because of cold temperature exposure lost in excess of 10 years of potential life, whereas the average person who died because of hot temperature exposure likely lost no more than a few days or weeks of life.

• Some 4,600 deaths are delayed each year as people in the U.S. move from cold northeastern states to warm southwestern states. Between 3 and 7% of the gains in longevity experienced by the U.S. population over the past three decades is due simply to people moving to warmer states.

• Cold-related deaths are far more numerous than heat-related deaths in the United States, Europe, and almost all countries outside the tropics. Coronary and cerebral thrombosis account for about half of all cold-related mortality.

• Global warming is reducing the incidence of cardiovascular diseases related to low temperatures and wintry weather by a much greater degree than it increases the incidence of cardiovascular diseases associated with high temperatures and summer heat waves.

• The adverse health impacts of cold temperatures, especially with respect to respiratory health, are more significant than those of high temperatures in many parts of the world, including Spain, Canada, Shanghai, and Taiwan. In the subtropical island of Taiwan, for example, researchers found low minimum temperatures were the strongest risk factor associated with outpatient visits for respiratory diseases.

• A vast body of scientific examination and research contradict the claim that malaria will expand across the globe and intensify as a result of CO2-induced warming.

• Concerns over large increases in vector-borne diseases such as dengue as a result of rising temperatures are unfounded and unsupported by the scientific literature, as climatic indices are poor predictors for dengue disease.

• While climatic factors largely determine the geographical distribution of ticks, temperature and climate change are not among the significant factors determining the incidence of tick-borne diseases.

• The ongoing rise in the air’s CO2 content is not only raising the productivity of Earth’s common food plants but also significantly increasing the quantity and potency of the many health-promoting substances found in their tissues, which are the ultimate sources of sustenance for essentially all animals and humans.

• Atmospheric CO2 enrichment positively impacts the production of numerous health-promoting substances found in medicinal or “health food” plants, and this phenomenon may have contributed to the increase in human life span that has occurred over the past century or so.

• There appears to be little reason to expect any significant CO2-induced increases in human health-harming substances produced by plants as the atmosphere’s CO2 concentration continues to rise.

These papers show that humanity prospered during warm times (e.g. the Renaissance period) and suffered during cold times (e.g. the “Dark Ages”).

EPA emission standards for trucks: heavy cost, no benefit

At a cost of only $30 billion, new EPA regulations may save us from 0.0026°C of global warming by the year 2100.

According to an EPA report (971 pages) [link]: “The Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA), on behalf of the Department of Transportation, are each proposing changes to our comprehensive Heavy-Duty National Program that would further reduce greenhouse gas emissions (GHG) and increase fuel efficiency for on-road heavy-duty vehicles,…”

The National Center for Policy Analysis estimates that “The Environmental Protection Agency’s second round of heavy-duty truck efficiency standards could cost more than $30 billion.” – costs that will be passed on to consumers.

“Auto manufacturers and the freight and long-haul transportation industry already understand the importance of fuel efficiency. Nearly 3 million heavy-duty Class 8 trucks carry approximately 70 percent of America’s freight, consuming more than 50 billion gallons in fuel and spending more than $140 billion in diesel costs. The industry operates on razor-thin margins and plans its driving routes down to the tenth of a mile to save on fuel costs.” – Nicolas Loris, The Daily Signal

The Obama administration says these new regulations are necessary to meet Obama’s carbon dioxide reduction goals.

The EPA claims “The proposed standards are expected to lower CO2 emissions by approximately 1 billion metric tons…”

So, what benefit will we get for $30 billion? EPA’s own figures show no benefit to the environment and no effect on global climate.

According to the EPA report linked above, the new regulations will accomplish the following (page 6-45): “As a result of the proposal’s emissions reductions from the proposed

alternative relative to the baseline case, by 2100 the concentration of atmospheric CO2 is

projected to be reduced by approximately 1.1 to 1.2 parts per million by volume (ppmv), the

global mean temperature is projected to be reduced by approximately 0.0026 to 0.0065°C, and

global mean sea level rise is projected to be reduced by approximately 0.023 to 0.057 cm.” Wow!

Among the first things the next President should do is to issue an executive order forbidding federal agencies from regulating carbon dioxide emissions and rescind all regulations that do so.

The U.S. Supreme Court recently ruled against the EPA on certain power plant emissions (see here). It remains to be seen whether the principles cited in that case will be extended to motor vehicles.
