PBS/Frontline documentary HEAT is for all you haters who don’t believe in climate change. Experts say that we’ve experienced climate change before, but not with 6.5 billion people living on Earth. By 2035 the Himalayan glaciers will have lost 80 percent of their ice, drying up rivers which millions depend on. What can we do to prevent this? Reduce carbon emissions by 60 to 80 percent before mid-century. The task is quite daunting considering the process of creating cement is the 3rd largest contributor to greenhouse gas emissions! With our government courting oil tycoons, the rapid growth of developing nations, our addiction to fossil fuels and the need for standard resources such as cement, the reversal process is a headache fever of global proportions.
