You should probably do your own homework. You should ask your teacher for extra help if you find it too difficult.

Global Warming: Causes: CO2 emissions are increasing. There are 2.1 trillion tons of CO2 in the atmosphere, we’re increasing this amount by about 1.381% each year, that means that in 72 years our emissions will equal the total amount of CO2 already in the atmosphere.Very carefully calibrated measurements have confirmed that CO2 is increasing in the atmosphere and that human activities are the primary cause. http://www.esrl.noaa.gov/gmd/ccgg/trends... http://www.grida.no/publications/vg/clim... http://www.realclimate.org/index.php/arc... CO2 is greenhouse gas. Increased CO2 will, in theory, lead to an increase in the greenhouse effect. Studies have proven there has been an increase in back radiation, proving there has been an increase in the greenhouse effect. http://earthobservatory.nasa.gov/Features/EnergyBalance/page7.php http://landshape.org/enm/wp-content/uploads/2009/01/philipona2004-radiation.pdf http://ams.confex.com/ams/Annual2006/techprogram/paper_100737.htm http://journals.ametsoc.org/doi/pdf/10.1175/2008BAMS2634.1 Effects: Increases in global temperatures. http://data.giss.nasa.gov/gistemp/graphs/ Stratospheric cooling. In theory, an increase in the greenhouse effect would lead to stratospheric cooling. As the lower atmosphere warms due to an enhanced greenhouse effect, the upper atmosphere is expected to cool as a consequence. The simple way to think about this is that greenhouse gases are trapping heat in the lower atmosphere. Since less heat is released into the upper atmosphere (starting with the stratosphere), it cools. Many studies show the stratosphere is cooling. http://www.geog.ox.ac.uk/~mnew/teaching/Online_Articles/jones_et_al_attribution_3d_GRL_2003.pdf An increase in the tropopause height. The tropopause height has increased several hundred meters over the past 3 decades. The tropopause is the atmospheric boundary between the troposphere and the stratosphere. Because the troposphere has warmed and the stratosphere has cooled, the tropopause has risen. http://www.math.nyu.edu/~gerber/pages/documents/santer_etal-science-2003.pdf Declining Arctic sea ice. Arctic sea ice is declining. In the last 50 years Arctic sea ice extent has been declining at a average rate of about 40,000 square kilometers per year. Retreating glaciers. Rising sea levels. Sea level is rising (Sea level rise is caused by the thermal expansion of sea water due to climate warming and widespread melting of land ice) Increases in ocean heat content Many of the other effects (of AGW) vary from region to region, so I've listed the consequences by continent. •North America: Decreasing snowpack in the western mountains; increased frequency, intensity and duration of heat waves in cities that currently experience them. •Latin America: Gradual replacement of tropical forest by savannah in eastern Amazonia; risk of significant biodiversity loss through species extinction in many tropical areas; significant changes in water availability for human consumption, agriculture and energy generation. •Europe: Increased risk of inland flash floods; more frequent coastal flooding and increased erosion from storms and sea level rise; glacial retreat in mountainous areas; reduced snow cover and winter tourism; extensive species losses; reductions of crop productivity in southern Europe. •Africa: By 2020, between 75 and 250 million people are projected to be exposed to increased water stress; yields from rain-fed agriculture could be reduced by up to 50 percent in some regions by 2020; agricultural production, including access to food, may be severely compromised. •Asia: Freshwater availability projected to decrease in Central, South, East and Southeast Asia by the 2050s; coastal areas will be at risk due to increased flooding; death rate from disease associated with floods and droughts expected to rise in some regions - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Declining Ozone: Causes: Ozone is gradually being destroyed by man-made chemicals referred to as ozone-depleting substances (ODS), including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, and methyl chloroform. Effects: Ozone depletion can cause increased amounts of UV radiation to reach the Earth which can lead to more cases of skin cancer, cataracts, and impaired immune systems.

Global warming/cooling, the climate of the earth... cause: The sun. Declining ozone? Another fairy tail. There has been an ozone hole since we could notice one, and it is unchanged, even after all the alarmists wishes were granted.

Why would this be a biology question, biology relates to the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution etc

hassle-free. If the dimensions is 5 ft greater effective than it extremely is width and the width is two ft then the dimensions would desire to be seven ft (2 plus 5). Perimeter is all aspects extra mutually so:- 7 + 2 +7 + 2 = 18 ft

seriously? you have all night to do your biology homework?!?! you probobally could have already finished it if you werent on the internet waiting for someone to give you the answers! how are you going to cheat when its time for an exam?

1. you should quickly scan all the topics you have gone over this year that may or may not be on the exam. (if your teacher gave you a list of topics then use that instead) (see step 4) 2. Don't spend much time on the topics you know really well (1-5Minute's max) 3. create a list of all the other topics and spend the majority of you study time going over these until you feel you know them. 4. Flash cards are a great way to remember what you know and what you don't you can create three piles... 1. I know well! 2. I'm not to sure about but I think I can manage and 3. I have no idea and really need to go over these. good luck with you exam I'm sure you'll do well!!!!
