What is the greenhouse

   Trapping and build-up of heat in the atmosphere (troposphere).
    Some of the heat flowing back toward space from the Earth's
    surface is absorbed by water vapor, carbon dioxide, ozone, and
    several other gases in the atmosphere and then reradiated back
    toward the Earth’s surface. If the atmospheric concentrations of
    these greenhouse gases rise, the average temperature of the
    lower atmosphere will gradually increase.
   Reference:{ glossary of climate change terms}
Carbon dioxide has kept at a
   constant high throughout
   650,000 years. Within the last
   few years the rate has gone up

Carbon dioxide is at is higher point
   now more than it has in the last
   650,000 years.
GLOBAL WARMING: An increase in the average temperature of the
earth's atmosphere, especially a sustained increase sufficient to
cause climatic change.

   The earth’s climate has changed for years. Throughout
    history both natural disasters and human negligence have
    played a great role in this change.
   Global warming has been caused by the rising of the earth’s
    temperature which has had a great effect on the earth’s
   Many gasses such as carbon dioxide, the burning of coal, oil,
    gasses burned in industries and the general pollution of the
    world have been the cause of this warming.
   This warmth has led to the melting of the ice glaciers, the
    incredible amounts of hurricanes and tornadoes that become
    greater and greater every year.
   Technology and the amount of gasoline we use to power our
    cars, industries, houses are all burning up and are helping to
    contribute to this disaster.
   The earth’s warming increases and decreases every year due to
    the tilt of the earth’s position, it rises gradually throughout the
   Such warmth in the sun and the melting of the glaciers raises the
    sea levels which cause more stronger hurricanes.
   As hot temperatures increase the wind velocity also increase,
    leading hurricanes to have a greater velocity and empowerment.
    Their category and eye become deeper and deeper.
   Global warming is a serious case in which many factors have to be taken into
    consideration. There is great amount loss that we will have to face in the years
    to come.
   The highest temperatures recorded worldwide in the northern hemisphere since
    the year 1880 was the year 2005.
   One of the fears of global warming is that there will be an intensity in the
    temperatures were they will always be at a constant high.
   Furthermore, we might have to face heat waves and droughts in surrounding
   Global sea levels could raise up to 20 feet which can overflow many states and
    other countries. For example the island of Manhattan will be completed under
    water, most of Florida state will be under water, the Shanghais area will have 40
    million people at risk.
   100 million people will become refugees of this great natural disaster.
   The world is a precious thing
    that we should take care of for
    it always takes care of us.
    Global warming does not just
    affects the lives of human
    beings but also many animals

    of extinct due to all the
    different temperature changes

    we all come together and put our efforts into using items
    that will conserve energy, recycle, use less gas, and just
    take interest and put effort we will be able to prevail.
