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.
But scientists attempting to analyse trends in its climate have been left with a puzzle. Earth's climate history for the past 10,000 years, some scientists say, shows consistent warming. Others, such as a study last year, suggest it was cooling until human activity reversed that trend.
