Human Health and Agriculture

A good part of the world and its countries rely on agricultureas their main source of income and of food

In a first scenario precipitation is expected to increase due toglobal warming, meaning that many crops will receive toomuch water and will be drowned as fields flood due to a

projected rise of 40 centimeters in sea level In a second scenario the amount of evaporation is expected to

increase due to global warming, meaning that even more cropswill die due to a lack of water

For many countries this change could mean death, in fact that

projected number of starving people worldwide is expected tobe 40-300 million people in addition to the 600 million alreadyprojected to be starving in 2060

Human Health and Water Supply

Due to global warming the amount of annualprecipitation and the amount of ice converted tofreshwater from the polar ice caps is projected toincrease

A rise in sea level is projected for 2100 of as much as40 centimeters

This rise in sea level could not only destroy humandwellings and human places of agricultural

production but could also destroy many sea-sideaquifers which would deplete the general watersupply for humankind

Human Health and Air Conditions

Due to global warming, the amount of smog that is

created by nitrous oxide, or ozone that is near the

ground, will increase

An increase in the amount of smog near the groundlevel could potentially result in fatally warm summer

days for those humans sensitive to such gases

As gases such as smog enter human lungs, they can

increase the potential of lung infection which can lead

to death

What else is affected byglobal warming?

Coral reefs- As the sea level rises the more and more coral reefs are beingkilled as they are subjected to cooler, darker waters

Greenland- The country of Greenland, a good percentage of which is madeup of ice, is likely to melt significantly should global warming continue,causing sea levels to rise significantly and drowning many coastalcommunities

The polar ice caps- As global warming continues the polar ice caps aremelting with speed and are diminishing all over the globe, causing manyanimals who inhabit the same areas as these polar ice caps to loose part oftheir habitats

Weather patterns- Weather patterns will greatly be affected by globalwarming as the weather must take into account a warmer climate

Wetlands- As sea levels rise due to global warming the number of wetlandsdiminishes as they are drowned by the rising waters

Predictions for the future:

The Hadley Center for Research on Climate Control has madea number of predictions about the future of climate change andits results by the 21st century, such as the following;

The surface temperature globally will have risen at an averageof 3.2 at a minimum of .3 worldwide The mean daily

precipitation will have increased by .2 millimeters globally The mean soil moisture will have decreased by a mean of 2

millimeters of moisture globally

The sea level will have decreased by a mean of .42 metersglobally

The volume and area of artic sea ice will have dramaticallydecreased

How can we help to stop/what is being

done to stopglobal warming? One way people can help to stop global warming is by using alternate forms of energy that are

not using up fossil fuels, products that create greenhouse gases when they are used

Some of the forms of renewable energy that have been suggested as alternatives are windenergy and solar energy

Another way we can stop global warming is by attempting to take greenhouse gases out of theatmosphere such as carbon dioxide, the main greenhouse gas, through techniques such ascarbon sequestration

There are four main ideas for carbon sequestration; to store carbon dioxide in the ground, tostore carbon dioxide in the ocean floor, to increase the abilities of certain plants and animalsto take in carbon dioxide from the atmosphere, and to look at the genome sequences of certainplants and animals who produce methane, hydrogen, or help to store carbon dioxide

Already a number of different projects are being done such as by Eric A. Davidson and NeilScott of the Woods Hole Research Center who are attempting to increase the carbonsequestration capacity of certain trees

The company Statoil, the State Oil company of Norway, is also already setting limits on howmuch carbon dioxide they can produce and are keeping their emissions at that level byinjecting any extra carbon dioxide their company produces into the sea floor off the coast ofNorway

cause global warming? (Slides 2-4)


8/15


What are two of the infectious diseases that

have a potential for becoming more prominent

as a result of global warming? (Slides 9-10)


9/15


What is one natural disaster that could become

potentially more harmful to humans due to

global warming? How would it be harmful

physically? Financially? Economically? (Slide

12)


10/15


How is it that global warming could cause the

sea level to become lower while it could also

cause the sea level to rise in certain areas of

the world?


11/15


What are some other ways that anyone at home

could help to reduce carbon emissions?
