    Study: Elevated levels of atmospheric CO2 threaten human nutrition

    At the elevated levels of atmospheric CO2 anticipated by around 2050, crops that provide a large share of the global population with most of their dietary zinc and iron will have significantly reduced concentrations of those nutrients, according to a new study led by Harvard School of Public Health (HSPH). Given that an estimated two billion people suffer from zinc and iron deficiencies, resulting in a loss of 63 million life years annually from malnutrition, the reduction in these nutrients represents the most significant health threat ever shown to be associated with climate change.

    My View:

    This is a truly fascinating study. Global climate change is going to affect us not just in the well known ways in terms of weather, etc. but also in so many subtle and unexpected ways.
