Group 6:

Future Climate Change Likely To Cause More Respiratory Problems In Young Children By ScienceDaily (May 4, 2009)

List at least 3 other common air pollutants.

State their source and explain the effects they have on human health.

Summary of Assigned Article

A problem that we might face due to climate change is the increase of temperature in certain areas of the world

such as New York City and metropolitan areas.However this does not mean that the surban areas would not be affected.


A model was done by Dr.Sheffield and her colleagues to predict the amount of children which would be affected by the future climate change and the results were compared to a previous results and the two differed by the amount of projected ozone precursor emissions. In both scenarios, ozone levels rise by 2020. The study found that by 2020, respiratory hospitalizations are projected to rise between four and seven percent for children.“These significant changes in children's hospitalizations from respiratory illnesses would be a direct result of projected

climate-change effects on ground-level ozone concentrations,” said Dr. Sheffield.

More children will end up hospitalized over the next decade because of respiratory problems as a result of projected climate change, according to a new study from Mount Sinai School of Medicine.


Ozone has many known negative respiratory health effects to which children are particularly vulnerable. An important projected consequence of climate change is the increase in ground-level ozone. Urban areas such as the New York City metropolitan area are at a higher risk of increasing temperature compared to rural areas. However, while more ozone is formed in higher temperatures, the downwind suburban areas are predicted in some of the models to experience higher ozone levels.


For this study, Dr. Sheffield and her colleagues created a model describing future projected rates of respiratory hospitalizations for children less than two years of age using baseline NYC metropolitan area hospitalization rates from publicly available corresponding state Department of Health databases.

Two separate future scenarios were used. The two scenarios differed by the amount of projected ozone precursor emissions (chemicals that are converted to ozone by light and heat).

In both scenarios, ozone levels rise by 2020. The study found that by 2020, respiratory hospitalizations are projected to rise between four and seven percent for children under two years old because of projected air pollution (ozone) increases. The scenario with increased ozone precursors showed less of an overall increase in hospital admissions because of a paradoxical reduction in ozone due to the effects of air pollutant interactions, sometimes referred to as the scavenger molecule effect. These are likely conservative estimates because population was held constant, a single dose response function was used for the entire area, and most counties were not weighted by race and ethnicity.







THREE Questions for Critques

(Answers to questions should be found in your wiki article.)

1.What problems will we face due to climate changes?

2.How much would respiratory hospitalizations increse by?

3.Is there a increase in the number of children affected by

the future climate change ?

Answers to Questions

1.ethanol derived from corn grown in Nebraska would require 50 gallons of water per mile driven, when all the water needed in irrigation of crops and processing into ethanol is considered.

2.ethanol or biodiesel

3.soil erosion


Three things good about the Article Review

i.Pictures about the article

ii.informations can be found

iii.Answer can be easily obtained


Two learning points from the Article Review

A)what kind of biofuels are there

B)What can we get from burning ethanol


One possible improvement for the Article Review

The article review is rather short as I browse the given links, there were a whole chunk of passages

Answers to Questions

1.Because green plants take in carbon dioxide and release oxygen.

2.Use the carbene to activate the CO2, then split off again to end the reaction cycle in its original state. The formal reaction partner is a hydrosilane, an organosilicon compound that acts as a reducing agent. The reaction product into which the CO2 is converted can easily be collected in the form of methanol in the last step of the reaction series.

3.Carbon atoms only has two electrons. The two electrons left over in the form of a lone pair, which makes this species highly reactive—reactive enough to attack CO2, and carbon dioxide atom is broken down.


Three things good about the Article Review

i.I gain knowledge about carbon dioxide.

ii.It teach me how to break down carbon dioxide.

iii.It shows us how important greenhouse effect is.


Two learning points from the Article Review

A) I learnt that Methanol is an important starting material for many chemical syntheses and serves as an alternative fuel and as a raw material for the production of energy in methanol fuel cells.

B) A common greenhouse gas was formed by unlocking the potential of carbon dioxide by converting it into a more useful product.


One possible improvement for the Article Review
