High-Tech Trash June is the wet season in Ghana, but here in Accra, the capital, the morning rain has ceased. As the sun heats the humid air, pillars of black smoke begin to rise above the vast Agbogbloshie Market. I follow one plume toward its source, past lettuce and plantain vendors, past stalls of used tires, and through a clanging scrap market where hunched men bash on old alternators and engine blocks. Soon the muddy track is flanked by piles of old TVs, gutted computer cases, and smashed monitors heaped ten feet (three meters) high. Beyond lies a field of fine ash speckled with glints of amber and green—the sharp broken bits of circuit boards. EEK! -Global Warming is Hot Stuff! Global warming is a hot topic (no pun intended). The Earth is warming up. While that may be hard to believe in the middle of a Wisconsin winter, if it's true it could mean big changes for our planet. For more info on this topic, browse on!

The Kids Guide To Global Warming People are seeing change all over the world. Arctic sea ice is melting earlier and forming later. Glaciers are disappearing. Heat waves, storms and floods are becoming more extreme. Island Institute (Ocean Acidification) A Climate of Change Workshop | Ocean Acidification Island and coastal communities are on the front line of environmental changes associated with climate change and ocean acidification. Across New England, fishermen and scientists are observing notable shifts in the ecosystem and dramatic changes in the number of fish in the water. Years of harvesting pressure paired with the effects of warming waters and an ever-changing ocean ecosystem have led to the crisis we currently face in the groundfish fishery.
Polar Bears and Climate Change Floods. Droughts. Heat waves. Massive storms.

A: Here's a simple definition of global warming. (And yes, it's really happening.) Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. And experts see the trend is accelerating: All but one of the 16 hottest years in NASA’s 134-year record have occurred since 2000.
Clean Air Kids: Greenhouse Effect & Global Warming The Earth is wrapped in a blanket of air called the 'atmosphere', which is made up of several layers of gases. The sun is much hotter than the Earth and it gives off rays of heat (radiation) that travel through the atmosphere and reach the Earth. The rays of the sun warm the Earth, and heat from the Earth then travels back into the atmosphere. The gases in the atmosphere stop some of the heat from escaping into space.
