“Climate Change Over Time”
a. In this lab, the question being investigated is, “Has climate changed over time?” b. The hypothesis is, “If CO2 levels affect climate, then the climate has changed overtime because of the increased greenhouse effect caused by higher levels of CO2 emissions.” c. Variables:
1. Independent Variable: Amount of CO2
2. Dependent Variable: Climate change
II. Background Information
Climate is the weather pattern in an area over long period of time. Climate is more focused on the long term rather than day to day or week to week changes. Due to uneven heating of the Earth’s surface, climate changes depending on where the location is on the planet. Factors such as incoming solar energy, Earth’s rotation, and air and water movements all affect an area’s climate. Different levels of these factors influence the biomes on the planet.
The current climate change is the warming of Earth’s atmosphere. Climate change has happened naturally all throughout history, but never to the degree that it is now. Average global temperature and CO2 levels are rising due to human activity on the planet such as increased agriculture, raising livestock, and burning fossil fuels. Now it is known that climate change is happening for a many reasons. Scientists studying ice cores, seafloor sediment, and tree rings are all seeing how the climate change is affecting the planet.
Even if immediate action is taken, there would still be lasting implications on the entire planet. Things such as rising sea levels, health implications, and severe droughts could all happen because of an increase atmosphere temperature. While some areas would be subjected to scorching temperatures, other would be plunged underwater. Warmer climate would allow for a longer breeding season for microbes and parasites. Action to stop climate change needs to happen as soon as possible before it could get worse.
