Please read the text below and answer the following question. A global temperature change of a few degrees is more significant than it may seem at first glance. This is not merely a change in weather in any one location. Rather, it is an average change in temperatures around the entire surface of the planet. It takes a vast amount of heat energy to warm every part of our world-including oceans, air, and land-by even a tiny measurable amount. Moreover, relatively small changes in the earth's surface temperatures have historically caused enormous changes in climate. In the last ice age 20,000 years ago, when much of the northern hemisphere was buried under huge sheets of ice, mean global temperatures were only about five degrees Celsius lower than they are now. Scientists predict a temperature rise of two to six degrees Celsius by 2100. What if this causes similarly drastic changes to the world we call home? Which sentence is the topic sentence?
