but we have nevertheless been polluting it for years.
The atmosphere can be divided vertically into four major layers : troposphere, stratosphere, mesosphere, and thermosphere.
Figure 2.1 The earth’s atmosphere is subdivided vertically into four major regions based on the air-temperature profile. The ozone layer that protects us from the sun’s UV radiation is in the stratosphere.
Seriousness of Climate Change
Temperatures around the world have increased -> melting glaciers and rising sea levels
Change of habitats, wildlife, cultures, artifacts and the life of humans.
changes in ecosystem, rainfall, desertification. -> flood, drought, typhoons, yellow dust, heat wave

temperature. Differential scanning calorimetry can be used to measure a number of characteristic properties of a sample.
Glass transitions may occur as the temperature of an amorphous solid is increased. These transitions appear as a step in the baseline of the recorded DSC signal. This is due to the sample undergoing a change in heat capacity; no formal phase change occurs.
As the tempera
