Other Resources for Poster Design

"Effective Poster Design." Effective Poster Design. N.p., n.d. Web. 22 Apr. 2014.

This site is very useful in helping design posters. There is a step by step instruction with further explanation 

for how to start and complete the poster. It is very easy to read and understand and I believe it has some 

very good tips.

"UNC Health Sciences Library." Design and Layout. N.p., 24 Mar. 2014. Web. 22 Apr. 2014.

This site is really helpful in the design of the poster from beginning to end, including the software being used 

to create the poster. This software includes three different versions of Microsoft PowerPoint as well as 

Adobe Photoshop. 

Tipping Points

The tipping points that I found in Emanuel (2007), UC Berkeley News Center, and Scientific American:

• Periodic oscillations of the Earth's orbit that primary effects the Earth's orientation
• Water vapor accumulates in the atmosphere, causing the atmosphere to warm, allowing more water vapor to accumulate
• Ice and snow can accumulate, making it's way toward the equator. The ice and snow would reflect sunlight back into the atmosphere causing the planet to continue cooling
• Arctic Sea ice has essentially diminished past a certain threshold, claiming that it will be a relatively rapid increase to losing all of the ice
• Major changes in the ocean currents or air circulation 
• Ocean temperatures or acidity

Quaternary Period

Here is my description of the Quaternary Period along with a figure, enjoy!

Test 2!

Right here is the link my second test! Enjoy!!

Tree Rings

Tree rings are one of the many proxies used to estimate the past's climate changes. As a tree grows in a year it produces a new ring, which varies in width allowing us to estimate the climate due to how much the tree grew. The trees that we focus on are normally found in a temperate climate, where they have a dry season. The trees that do not have a dry season end up growing year round and that makes it hard to determine any climate changes because the rings are not defined to one per year. The trees growth are influenced by precipitation, temperature, sunlight and wind. All of these factors can help us determine the climate of that specific growing season. Trees can grow for thousands of years and hold data from all of the past climates. When the tree rings are thicker that normally points toward a climate that favors the growth of the trees, while having narrow means the opposite. With the amount of data that has been collected scientists are able to estimate from hundreds to thousands of years in the past locally. By combining this proxy with other proxies scientists have been able to estimate regional and global climates.

Climate Change Videos

For the first video, located here, I feel as though the main take home message was that before humans were involved, there was a clear pattern that the Earth was going through. The globe would cool down and have an inter glacial period and then warm back up. Then from that point on it would cool down until another ice age occurred, and this pattern continued. Since humans have been involved, the amount of CO2 in the air has sky rocketed, and doesn't look like it is going to shrink any time soon.

In the second video, which you can find here, the sole purpose of this video also seemed to be toward end. With all of the data that paleoclimatologists gather from proxies such as corals, ice cores and tree rings the temperature of the globe is still hotter than the past thousand years. Even with the room for error, this still holds true. Between the first and the second video, there is a strong motif of the fact that the planet is a little off it's regular course.

The main idea for the third video, found here, seemed to be that the climate of the environment around lakes impact the lake itself. When the climate is warmer it effects the plants and their growth as well as the particles that are spread into the water.When these are measured you are able to find out information about the environment during a specific time period.
