In the video for the Greenhouse Affect I think it was very helpful for me to better understand what it was and how it worked. I learned that the Greenhouse Affect basicly keeps us alive because it keeps all the heat in the atmosphere instead of letting it just float off into space. This happens because of green house gases such as carbon dioxide.

After talking the Global Warming Quiz I know even more about green house gases, global warming, and their affect on the human society. I learned that green house gases are more effective in the day then at night and that China sends out the most general pollution into the atmosphere.

3 Reason Global Warming Reflection
A couple things that cause global warming are carbon dioxide, or CO2, methane realesed from landfills and or agriculture, nitruos oxcide from fertilizers, gases used for refrigeration or other industrial processers, deforestation, but mostly from the combustion of fossil fuels (vehicles and other industrial products), factories and electric usage. thanks to Nick Ratigan or Z1-N.R. for some facts and an idea on how to write this reflection. 1.fossil fuel combustion 2.carbon dioxcide 3.methane

Is Global Warming Real Reflection
Over the last couple of decades temperatures all over the world have been creeping upward. Earth's average temperature has gone up over 1 degree F, or 0.8 degree C,. Scienctists know how the temps. were hundreds or even thousands of years ago because of the rings on trees. As a tree gets older it grows rings, depending on the climate the rings will be wider (thicker) or smaller. Scientists can also look back in the past at the bottom of lakes or oceans. When pollen, creatures, and particles fall to the bottom of lakes and oceans they form sediments. Sediments preserve all the bits and pieces, which contain information about how the climate was, when they fell.

In our climate moderate change in early decades is projectedto increase yields of rain-fed agriculture by 5-20% but will vary among regions. challenges are projected for crops that are near the warm end of their range or depend of highly-utilized water resources.

Surprising signs of global warming are appearing all over the world. The heat id not only melting glaciers and sea ice but is shifting rain patterns and setting animals on the move. Researcher Bill Fraser tracked the Adelie penguins on Antarctica and found that breeding pairs fell from 32,000 to 11,00 in 30 years. Some other effects of global warming is that some butterflies, foxes, and alpine plants moved north to higher, and or, cooler grounds. Spruce bark beetles have chewed up 4 million acres of spruce trees thanks to 20 years of warmth.

__If global warming continues__ sea level is expected to rise 7-23 inches melting at the poles is expected to rise 4-8 inches hurricanes and other storms are expected to be stronger floods and droughts are expected to be more common Ethiopia's rainfall could decline by 10% over the next 50 years if Quelccaya ice cap, in Peru, continues melting at it's current rate it will be gone in 2100 disease is expected to spread

Reduce Global Warming
1. to ride a bike, walk, or carpool instead of driving cars individually 2. use more electric powered objects than gas powered objects 3. reduce deforestation to store more CO2 my project is going to be on deforestation and how it affects us as humans.
