Quantifying the health impacts of future changes in temperature in California.

Ostro, Bart; Rauch, Stephen; Green, Shelley
| Idioma(s): Inglés
BACKGROUND: Several epidemiological studies demonstrate associations between high summer temperatures and increased mortality. However, the quantitative implications of projected future increases in temperature have not been well characterized. OBJECTIVE: This study quantifies the effects of projected future temperatures on both mortality and morbidity in California, including the potential effects of mitigation. DATA AND METHODS: We first estimated the association between temperature and mortality for populations close to weather stations throughout the state. These dose-response estimates for mortality were then combined with local measures of current and projected changes in population, and projected changes in temperature, using a baseline of average temperatures from 1961 to 1990, for the years 2025 and 2050. The latter were based on two greenhouse gas emissions scenarios (A2 and B1) developed for the Intergovernmental Panel on Climate Change. In addition, we assessed the impacts of future adaptation through use of air conditioners. Several sensitivity analyses were conducted to determine the likely range of estimates. RESULTS: These analyses indicate that for the high emissions scenario, the central estimate of annual premature mortality ranges from 2100 to 4300 for the year 2025 and from 6700 to 11,300 for 2050. The highest estimates are from the models that use age-specific dose-response functions, while the low estimates are from the models that adjust for ozone. Estimates using the low emissions scenario are roughly half of these estimates. Mitigation based on our estimates of the effects of 10% and 20% increase in air conditioner use would generate reductions of 16% and 33% in the years 2025 and 2050, respectively. CONCLUSION: Our estimates suggest significant public health impacts associated with future projected increases in temperature.

Burning Fossil Fuels: Impact of Climate Change on Health.

Sommer, Alfred
| Idioma(s): Inglés
A recent, sophisticated granular analysis of climate change in the United States related to burning fossil fuels indicates a high likelihood of dramatic increases in temperature, wet-bulb temperature, and precipitation, which will dramatically impact the health and well-being of many Americans, particularly the young, the elderly, and the poor and marginalized. Other areas of the world, where they lack the resources to remediate these weather impacts, will be even more greatly affected. Too little attention is being paid to the impending health impact of accumulating greenhouse gases.

Cambio climático, su impacto en la salud y las plantas medicinales/ Climate change, its impact upon health and medicinal plants

Morón Rodríguez, Francisco J
| Idioma(s): Español
El impacto nocivo del cambio climático sobre la salud ha sido ampliamente documentado en publicaciones por la Organización Mundial de la Salud (OMS)1,2 y científicas;3,4 numerosas referencias aparecen en bases de datos como PubMed que indexa 1 864 bajo climate change AND health, aunque solo 54 para climate change AND health impact. Sin embargo, su efecto sobre las plantas medicinales, que constituyen una importante fuente real y potencial para la obtención de nuevos principios activos y medicamentos; así como, son el casi único recurso para la salud de poblaciones de bajos recursos, es mucho menos abordado. Apenas se encontraron 7 citas con las palabras clave climate change AND medicinal plants y 19 con climate change AND herbs (consulta en la Web el 26 de enero de 2013 http://www.ncbi.nlm.nih.gov/pubmed).Parece no existir conciencia suficiente de la amenaza que el cambio climático representa para todos los seres vivos, como las plantas en general y las medicinales en el contexto internacional. Los propios documentos citados de la Organización Mundial de la Salud,1,2 se refieren indirectamente a las plantas cuando mencionan el efecto sobre la producción de alimentos1,2 y al expresar: abogar por el fortalecimiento de los servicios de atención primaria de salud (incluida la prevención primaria) para reforzar la capacidad de las comunidades locales de afrontar los riesgos sanitarios relacionados con el clima en la medida propuesta número 4.2.1...
