Myth: Global warming will adversely affect worldwide food production. Fact: Exactly the opposite. Warmer weather will open much more land to agriculture (at higher latitudes) and the rising CO2 will stimulate plant growth and the plants will require significantly less water. (Idso, Craig, 2009, personal communication).
Myth: Higher temperatures kill people.
Fact: A half-truth at best. Higher temperatures can cause deaths but, according to health officials, many more people die each year from cold weather than from hot weather.
Just read the news after the strong winter storms.
Myth: Made-made CO2 emissions will lead to more deaths from heat waves.
Fact: The U.S. population has become less affected by heat waves during the past 30 to 40 years and the more frequent heat waves occur, the better prepared we are for them.
Scientific studies have shown that the more often that we are subjected to heat waves, the less we are affected by them. In cities across America, as temperatures have increased primarily through the processes of urbanization, fewer and fewer people have been dying from extreme heat. In fact, the hottest places in the country (places where extreme beat is commonplace) have the fewest incidences of heat-related mortality. -
The Figure below shows these two effects-declining heat-related mortality over time and fewer heat deaths in places with the highest summer temperatures. For each major city across the U.S., there are three bars plotted in the Figure, the height of which represents the average number of heat-related deaths (standardized for population differences) for the past three decades (the leftmost bar is the 1970s, the middle bar is the 1980s, and the rightmost bar is the 1990s).
In nearly all cities, the average number of heat-related deaths has been noticeably declining-meaning that the population of those cities has become better adapted to heat waves. This adaptation is most likely a result of improvements in medical technology, access to air-conditioned homes, cars, and offices, increased public awareness of potentially dangerous weather situations, ~ proactive responses- of municipalities during extreme weather events and an increase in overall wealth of the citizenry.
Myth: Man-made CO2 emissions will endanger the health and welfare of humanity.
Fact: Absolutely false. First, CO2 is in no way a pollutant. Second, Additional CO2 will be a great benefit to the production of more food as well as to the general "greening" of Earth and her habitats and ecosystems. Third, humanity now lives in the climate extremes of the Earth so is very adaptable to what small impact CO2 may have in contributing to other natural causes of warming.
People frequently and voluntarily relocate themselves to climates that are much warmer or much cooler. Health wise, peer reviewed statistics indicate that heart attacks, strokes and respiratory deaths are much less frequent in Earth's warmer climates.
Myth: Warmer weather will cause more malaria.
Fact: According to Dr. Paul Reiter of the world-renowned Pasteur Institute, this is not true (Reiter, Paul, 2009, personal communication).
Malaria was much more prevalent, having already extended into Siberia, decades before the most recent warming.
