Stark before-and-after evidence of how cast polymer has changed since the 1990s: the nrxt photo (below) shows a custom bathtub and shower made with white cultured marble, now known as engineered composite. The âafterâ photo (pictured here) is a granite-look engineered composite remake, called Venetian Gold, produced by Mobile Marble (Mobile, Ala.).
While polls of scientists actively working in the filed of climate science indicate strong general agreement that Earth is warming and human activity is a significant factor, 31,000 scientists say there is no convincing evidence that humans can or will cause catastrophic heating of the atmosphere.
In the heat waves of 1936, more than 4,768 Americans died from heat and high humidity. Because humidity affects the body's ability to cool itself, biometeorologists -- scientists who study the relationship between weather and life -- have looked for ways in which to combine the air temperature and humidity. First, let us look at how the body reacts to heat and the role humidity plays in cooling the body. Then we will look at the indices which the Canadian and American weather services use to alert the public to the potential dangers of high heat and humidity.
