15. Air pollution can cause lung cancer

16. air pollution have reduced the atmosphere filter to filter out the sun's harmful rays

17.smoke from a power plant can   harm the atmosphere.

18.Global warming affects plants  by causing seasonal changes in temperature to occur at different times of the year.

19.  Earth's average surface temperature will rise an additional 2.0 to 11.5 Fahrenheit degrees by 2100

20. if warming continues unchecked, it will damage human society and the environment

21. Scientists project that 20 to 30 percent of species would face a higher risk of extinction if the average temperature rose more than 2.7 to 4.5 Fahrenheit degrees

22. Average sea level rose about 7 inches if this keeps up it can flood areas

23. if global warming goes on then there will be more frequent and intense hot days and heat waves

24.Researchers project that further warming could cause sea level to rise another 7 to 23 inches higher then the sea level right now

25. Researchers predict that global warming will lead to more extreme weather

1.)Plants can absorb carbon, but they cannot decree the temperature

1.)Some countys are taking action sepately
2.)but some country's are taking action together
3.)scientists believe that for anything to change all of the country's need to work together
4.) The kyoto protocol is when WEALTHY countries agree to lessen the usage of co2
5.) and the most obvious, lessen our use of fossil fules

1.)Geoengineering allowes us to alter the environment to counteract global warming

2.)sequestration is when we prevent co2 from entering the atmosphere, or taking it out of the atmosphere

1.) biofuel is a fuel we can use for cars,trucks, and busses instead of fossil fuels
2.) It can be made out of corn husks and other plant materials

1.) climatologists loo at trees to see when the climate was most favorable for them
2.)climatologists study cores of ice from antarctica and greenland to see how high anchent levels of greenhouse gasses where to compare to today

1.) the change of warmth in ocean causes more natural disasters like hurricanes
2.) with snow on mountains melting, eventually their will be droughts for certain mountain community's 
3.) forest fires(wild or not) lets all of the carbon dioxide(as much as 50 lbs per tree)into the air that was stored in the trees

1.) some people don't believe in climate change like politicians looking for money

1.) cow manure creates methane which is a powerful greenhouse gas
2.) tractors use diesel fuel which is bad for the environment
3.) crops catch on on fire also relice co2 

8. Climate change is widely considered to be one of the most critical environmental issues currently facing the global community.
9. Greenhouse gases trap warmth from the sun in Earth’s atmosphere, preventing gases from escaping.
10. A buildup of gases causes the planet to retain more heat than it otherwise would.
11.
13. During the twentieth century,Fossil fuel–powered industrial production continued to spread at a rapid pace during the nineteenth century, and it is during this time that scientists believe the first signs of climate change began to appear.
12. Researchers looked at historical temperature records dating back to the nineteenth century, noting that they began to show a distinct warming trend in industrialized areas during this period. industrialization spread to virtually every region of Earth and accelerated the greenhouse effect.

14. Scientist believe that rising Arctic temperatures may cause nearly all of the summer sea ice, that the polar bears depend on for survival, to vanish by 2040.
15. Birth rates of polar bears are failing, fewer cubs survive and more and more bears are drowning.
16. More than 25% of the world's polar bear population has already declined; further global warming could drive this animal to extinction by the end of this century
17. "Birds are laying eggs earlier than usual, plants are flowering earlier and mammals are breaking hibernation sooner," said Terry L. Root, a senior fellow at Stanford's Institute for International Studies.
18. About 70 species of frogs have gone extinct due to global warming.
19. Oxygen levels in the Baltic Sea have been because of increasing temperatures. Because of that it has reduced fish populations. Fish need oxygen in warmer waters.
20."Birds are laying eggs earlier than usual, plants are flowering earlier and mammals are breaking hibernation sooner," said Terry L. Root, a senior fellow at Stanford's Institute for International Studies.
21. Polar bears will soon be treading water in the Arctic Ocean  because of our mistakes.

22. Smaller animals have fewer offspring.
23. Scientists have established a rule called the "temperature size rule" which is saying that individual animals reared at colder temperatures will become larger adults. But animals reared in warmer temperatures became smaller adults.
24. "If you warm up, you put on mass more quickly, but the rate at which you pass through life stages is even faster, and when you reach an adult size, you end up being smaller at warmer temperatures," says Jack Forster, a doctoral student at Queen Mary, University of London, and the lead researcher.
25. A new scientific study has examined how warmer temperatures have resulted in smaller animals.
