On Thursday the 11th of September at 3:30, in the Leacock building of McGill university, I attended a seminar on ” Health risks of climate change ” given by Dr. Kristie Ebi.
She drew a rather critical portrait of the earth situation. In her opinion, even if we stopped emitting greenhouses gases, we still could have 50 years of climates rising to come. Climate changes have many impacts on human health. One particular example she gave was the increasing number of catastrophes such as hurricanes (e.g., Katrina) and major heat waves (like the one that hit Europe in August). The problem also resides in the fact that the cities are not prepared to face such treats. During the major heatwave that hit Chicago, they stored the affected person in refrigerator vans because they had no where to put such a large amount of people. However, she explained that the required changes will not be easy to accomplish. For example, in prevision of sea level rise and future hurricanes, some flood lines have to be moved. This will not please the entrepreneurs nor the owner of the fields who suddenly would find themselves in a flooding zones. Insurance policies will increase.
An another important issue raised in this seminar was the fact the human health is never included in the planing for future development. As a matter of fact, rising temperature affect humans, animals but also pathogens. Epidemics of samonela, malaria, diarrhea, malnutrition and other wonderful infectious vectors will spread further with increased temperature. Furthermore, some solutions to the problem may enable those parasites to access new areas. For example, a plan in China will have a river from the south redirected toward a river in the north. The southern river is contaminated with a pathogen that is currently unable to reach the northern part of the country. For now, it is impossible for the pathogen to move because of the low temperature but with the climate change, it will have access and millions of new people will be subject to infection.
To conclude, it is crucial that the countries prepare for those catastrophes (it was done for the last el nino and the result were impressive) and health should considered when doing so.
