Stop Global Warming

Science, global warming?

by: Brown Sugar…Based on past and current patterns, which of the following is the most logical deduction?

a. As the population declines, global temperature will cool significantly because the rain forest will re-grow.
b. If populations continue to rise, CO2 emissions will reduce in proportion and temperatures will climb.
c. As human population increases, CO2 emissions will increase and global temperatures may continue to climb.
d. Continued rain forest destruction will cause a lowering of atmospheric CO2 , lowering temperatures and pushing us into an ice age.
e. Acid rain will be reduced, slowing the depletion of the ozone and countering the possible effect of global warming.

What two facts support the theory of global warming?

a. Earth’s temperature is getting warmer and dust pollution is increasing.
b. Earth is getting cooler and smog formation is increasing.
c. Man is adding about 7 billion tons of CO2 to the atmosphere each year and ozone depletion is happening.
d. Human activities add about 7 billion tons of CO2 to the atmosphere each year and CO2 traps heat better than the atmosphere.
e. Rain forest are being burned down and the smoke and soot has a cooling effect on the atmosphere.

Which of the following shows two ways that destruction of the rain forest may increase the possibility of global warming?

a. Burning the rain forest releases CO2 and as living trees grow they remove CO2 . Thus, it has a double impact on the global warming threat.
b. Burning the rain forest stops the trees from removing the CO2 and causes extinction of many plant and animal species.
c. Burning the forests reduces the production of natural ozone and increases acid rainfall.
d. Rain forests are the source of nearly all coal and burning the coal causes increased change of warming temperatures.
e. All of these are ways that destruction of the rain forest will increase the chance of global warming.
