Greenhouse_Effect

Greenhouse Effect The greenhouse effect as stated in the dictionary is the effect produced as greenhouse gases allow incoming solar radiation to pass through the Earth's atmosphere, but prevent most of the outgoing infrared radiation from the surface and lower atmosphere from escaping into outer space. This process occurs naturally and has kept the Earth's temperature about 60 degrees Fahrenheit warmer than it would otherwise be. Current life on Earth could not be sustained without the natural greenhouse effect. Weather stations, balloons, ocean buoys, and satellites tell us the Earth’s temperature today. Ice cores, sediment layers, and tree rings tell us about what the Earth’s climate has been like in the past. With this evidence, scientists are learning how climate changes over time. Climate is the long-term average of a region's weather events lumped together. Climate change represents a change in these long-term weather patterns. They can become warmer or colder. Annual amounts of rainfall or snowfall can increase or decrease. Human activities are increasing greenhouse gas concentrations and trapping more heat. The Earth’s climate is predicted to change due to the buildup of greenhouse gases; the associated rate of temperature change is significantly faster than any observed changes in the last climate, warming, global, change, greenhouse, changes, health, people, human, gases, increase, water, temperature, atmosphere, about, very, temperatures, scientists, heat, warmer, impacts, natural, level, emissions, diseases, risks, places, increases, earth, deaths, areas, occur, make, gas, effects, effect, warm, states, ozone, much, energy, electricity, earth's, during, air, activities, weather, vulnerable, over, number
