Global Warmming

Global warming: The Greenhouse Effect: Scientists are sure about the greenhouse effect. They know that greenhouse gases make the Earth warmer by trapping energy in the atmosphere. Climate Change:Climate is the long-term average of a region's weather events lumped together. For example, it's possible that a winter day in Buffalo, New York, could be sunny and mild, but the average weather – theclimate – tells us that Buffalo's winters will mainly be cold and include snow and rain. Climate change represents a change in these long-term weather patterns. They can become warmer or colder. Annualamounts of rainfall or snowfall can increase or decrease. Global Warming: Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmerEarth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern isabout global warming caused by human activities. Weather: describes whatever is happening outdoors in agiven place at a given time. Weather is what happens from minute to minute. The weather can change a lot within a very short time. For example, it may rain for an hour and then become sunny and clear.Weather is what we hear about on the television news every night.
