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.
Important challenges. for climate scientists are to identify all the factors that affect climate and the mechanisms by which they exert a forcing, to quantify the. radiative forcing of each factor and to evaluate the total radiative forcing from the group of factors. FAQ 2.1, Figure 2.
