Health Effects of Global Warming

Technical Rating: star
This article reviews three papers on the health effects of warming. A study published in 2015 examined 74 million deaths worldwide from 1985 to 2012 and found that the ratio of cold-related to heat-related deaths was a whopping 17 to 1. A study of heat-related deaths in the USA shows that as heat waves become more frequent, heat-related deaths decrease because of adaptation. There were 41 heat-related deaths/year/million population is the 1960s and 1970s dropping to 17 in the 1980s and to only 10 in the 1990s. A 2017 study of temperature-related hospital emergency visits in China over the period 2011–2014 shows that the risk is far greater for cold temperatures than for hot temperatures. When temperatures fall the risk of an emergency visit increased by 80% but when temperature rise the risk increases by only 15%. The length of hospital stays due to cold temperatures are ten times greater than that due to hot temperatures.

Climate and Epidemics in China

Technical Rating: star
This paper analyzed the relationship between climate and infectious disease epidemics in China over the period 1370-1909 AD. There were a total of 5961 epidemic incidents in China during the period. The level of precipitation was not significantly correlated with epidemic count. The scientist found that in China a standard deviation decrease in temperature (about 0.8 °C) caused an increase of 162 epidemic outbreaks. The abstract says “cooling drove up epidemic outbreaks in northern and central China…”. This directly contradicts integrated assessment models that assume warming causes more disease and social cost.

Winters not Summers Increase Mortality and Stress the Economy

Technical Rating: star
Global warming alarmists continue to over-emphasize the danger of heat and ignore cold in their papers and in stories for the media. The danger associated with this misdirection is that cold weather kills many more people that hot weather. Cold weather kills 20 times as many people as hot weather, according to an international study analyzing over 74 million deaths. The Canadian death rate in January is more than 100 deaths/day greater than in August, for the years 2007 to 2011. The USA economic growth rate is much greater in warm months than in cold months.

Twenty Good Reasons Not to Worry About Polar Bears

Technical Rating: star
Polar bear expert Dr. Susan J. Crockford, Ph.D., University of Victoria, B.C. has prepared a document listing 20 good reasons not to worry about polar bears. She says "so let’s celebrate the recent triumphs and resilience of polar bears to their ever-changing Arctic environment." The document shows that "polar bears are a conservation success story". Some reasons to be optimistic: There are more polar bears now than there were 40 years ago. Only 2 of 19 subpopulations are "likely in decline", down from 10 in 2010. There has been only a marginal decline in total sea ice extent during the critical spring feeding period. The document has maps, graphs and numerous links to supporting information.

Canada's Growing Polar Bear Population 'Becoming a Problem'

Technical Rating: star
The chairman of the Nunavut Wildlife Management Board says the polar bear population along the Davis Strait has doubled during the past 10 years. This article shows that there is a huge gap between model projections of polar bear populations and observations from local people.
