On the trip to the museum of American National History, me, La’Relle, and Richelle we discovered a lot of new information about the environment and global warming. Global warming is a major problem that can effect our environment and our lives if we do not act in time to prevent it. Here is some of the information that my partners and I have retrieved from the museum.
Ozone: A stratosphere story
At the earth’s surface, ozone is a pollutant, but its presence in the stratosphere is critical in protecting life. Formed by a complex chain of reactions, ozone absorbs harmful ultraviolet radiation from the sun, preventing it from reaching the earth’s surface. Stratospheric ozne is increasingly being destroyed by man-made pollutants.
Carbon dioxide and Global Warming
The amount of carbon dioxide (CO2) in the atmosphere is related to global temperature: as the earth warms, CO2 increases & vice versa. Measuring CO2 in ice cores provides a record of atmospheric CO2 variation over thousands of years-from one glacial period to another. By tracking the natural variability of CO2, scientists have discovered that the recent rise in atmospheric CO2 has been caused by human activities
