Climate Change Science

Glacier melting:Peru's Quelccaya ice cap is the largest in tropics. If it continues to melt at the current rate, it will be gone by 2100. If it melts away completely it will leave thousands who rely on water, electricity high dry and in the dark.

When the president's draft created the glacier national park in 1910 there were 150 glaciers, no there is less than 30 glaciers left. "Things that normally happen in geologic time are happening during the span of a human lifetime," Says Fagre. "It's like watching the statue of liberty melt." Even the famed snows of Kilimanjaro have melted more than 80% since 1912. Most of the central and eastern Himalayan glaciers could virtually disappear by 2015. Arctic sea ice has thinned out over the past 30 years. Spring freshwater ice breakup in the northern hemisphere now occurs nice days earlier than it did 150 years ago. When temperatures rise and ice melts, more water flows to the seas from glaciers and ice caps. Many Alaskan glaciers have retreated and thinned dramatically over the past years. From 1941 to 2004 is has retreated about 7 miles. After the satellite era started in 1970 it has shown us the rapid decrease in glaciers.

Clean Energy: Power generation is one of the leading causes and largest source of U.S. global warming. Nuclear energy, natural gasses, coal, and oil not only pollute the air but also pollutes the

water. This shows the rapid increase of CO2 since the industrial revolution.
