What is Global Warming?

“Global warming is an average increase in the temperature of the atmosphere near the Earth’s surface and in the troposphere, which can contribute to changes in global climate patterns. Global warming can occur from a variety of causes, both natural and human induced. In common usage, “global warming” often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human activities.”

CAUSES

As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere. Certain waste management and agricultural practices aggravate the problem by releasing other potent global warming gases, such as methane and nitrous oxide.

EFFECTS

Of course, land and ocean temperature is only one way to measure the effects of climate change. A warming world also has the potential to change rainfall and snow patterns, increase droughts and severe storms, reduce lake ice cover, melt glaciers, increase sea levels, change plant and animal behavior, forest fire, flashfloods and more.

SOLUTIONSAGENDA

Boosting energy efficiency Greening transportation Revving up renewables Ensuring sustainable development

Phasing out fossil fuel electricity Managing forests and agriculture Developing and deploying new low-carbon and zero-carbon technologies
