For hundreds of years alchemists toiled in their laboratories to produce a mythical substance known as the philosopher’s stone.The supposedly dense, waxy, red material was said to enable the process that has become synonymous with alchemy— the metamorphosis, or transmutation, of base metals such as lead into gold.As you can see from Graph 2, the larger the coefficient the greater the 'starting amount'.Conversely, the smaller coefficients lead to smaller/lower 'starting amounts'.

From top to bottom: * Levels of carbon dioxide (CO2). High rates of snow accumulation provide excellent time resolution, and bubbles in the ice core preserve actual samples of the world’s ancient atmosphere[6]. Scientists want measurements that are both accurate and precise…but it can be difficult to tell sometimes whether very precise measurements are actually accurate without an independent reference age (see top right image versus bottom right image).Typically, we do not even consider the negative x values because the x-axis typically represents time.

In short, the half life tells us the scale of the graph. By looking at past concentrations of greenhouse gasses in layers in ice cores, scientists can calculate how modern amounts of carbon dioxide and methane compare to those of the past, and, essentially, compare past concentrations of greenhouse gasses to temperature. Ice cores have been drilled in ice sheets worldwide, but notably in Greenland[3] and Antarctica[4, 5].
