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.
Climate scientists prefer to combine short-term weather records into long-term periods (typically 30 years) when they analyze climate, including global averages. Today's global temperature is typically measured by how it compares to one of these past long-term periods. For example, the average annual temperature for the globe between 1951 and 1980 was around 57.2 degrees Fahrenheit (14 degrees Celsius).
