Global Warming or Climate Change?
Just like many other websites and personal blogs, on this site the terms global warming and climate change are used very interchangeably. But what is the actual difference between these terms? In moving forward, there is an important difference that I recommend you should at be aware of.
As you may recall, we previously defined global warming as the gradually increasing trend in the overall temperature of the earth’s atmosphere. According to the National Oceanic and Atmospheric Administration, the earth’s combined land and ocean temperature has increased at an average rate of 0.13 degrees Fahrenheit ( 0.08 degrees Celsius) per decade since 1880. In addition, the average rate of increase after 1981 has more than doubled to 0.32°F (0.18°C ) per decade.
In addition to this increase in temperature, scientists have a large amount of confidence that global temperatures will continue to rise in the future, largely due to greenhouse gases produced by human activities. Along these lines, the Intergovernmental Panel on Climate Change has predicted that temperatures will continue to increase at least 2.5 to 10 degrees Fahrenheit over the next century.
These small changes in temperature correspond to large impacts on our environment. Climate change is defined as these long-term changes in the weather patterns that come as a result of temperature change. Global warming is the cause, climate change is the effect.
The end result of these changes in climate is a multitude of different symptoms and effects. They include an impact both on rainfall and weather patterns, ranging from extreme weather events like heat waves, to droughts, to forest fires, to hurricanes, the melting of ice caps and glaciers, and,.. as the ice melts,- the rising of the sea levels. And that’s just to name a few. There are many more ripple effects that follow.
