Ice ages have happened a number of times throughout Earth’s history. The Latest Ice Age The latest ice age began more than 1.8 million years ago and ended [...]
Why is the present rapid warming happening?
Why is the present rapid warming happening? Scientists believe the rapid warming in the last several decades is due mostly to human-induced changes to the atmosphere, on top of some natural variations. Climate change induced by human activity may occur due to changes in the composition of the Earth’s atmosphere from waste gases due to [...]
Can Pollution Stop Global Warming?
Can Pollution Stop Global Warming? The Earth is a bright planet. From space, we see why. More than half our world is covered with clouds at any one time. Those clouds reflect a lot of sunlight back to space, helping keep our planet relatively cool. But a NASA satellite instrument called MODIS is showing us that humans can change our planet’s [...]

Glaciers and climate
Glaciers and climate Glaciers act as slow-response weather instruments, growing when temperatures fall and/or more snow falls, shrinking when temperatures increase and/or less snow falls. They respond only to environmental trends that last a few decades, therefore their trends are useful for climate studies. Some glaciers occasionally surge, [...]
