Glaciers accumulate snow in the winter, and then melt ice in the summer. Cold temperatures, more snow, or both,... click to read more

The average temperature on Earth rose dramatically during the last century. This is due to human activity, which led to the increased atmospheric concentration of certain gases, typically called greenhouse gases. These gases increase the solar heat trapped by our planet. The greenhouse gas methane... click to read more
