Deaths caused by global warming


Global warming will cause more deaths in summer because of higher temperatures but these will not be offset by fewer deaths in milder winters finds an analysis published online ahead of print in Occupational and Environment Medicine.

The Harvard researchers analysed city-specific weather data related to the deaths of more than 6.5 million people in 50 US cities between 1989 and 2000.
They found that during two-day cold snaps there was a 1.59% increase in deaths because of the extreme temperatures. However, during similar periods of extremely hot weather death rates went up by 5.74%. Deaths did not rise as steeply when temperature fluctuations were less extreme.
Deaths from all causes are known to rise when temperatures go up, and heart attacks and cardiac arrests are more likely when it is very cold. It was anticipated that global warming would increase deaths during hot temperatures but that this would be compensated for by fewer deaths in the winter.
But the authors conclude: ‘Our findings suggest that decreases in cold weather as a result of global warming are unlikely to result in decreases in cold-related mortality in the US. Heat-related mortality, in contrast, may increase, particularly if global warming is associated with increased variance of summer temperature.'

  1. We must take preventive measures inmediately because if it does occur will be caused by man and that we do nothing to prevent global warming, such as not using cars, not burn trash and others.

  2. this is incredible, the numbers are very high for this type of problem, I think we should start with education about this from the primary to be more aware of the effects of heat, well that's what I think

  3. I think the climate is very important because where I live if it gets too cold in these seasons and is one of the main factors for which there respirtorias diseases.
