HI! WE have a fair in our school,And we have to make a model representing global warming mainly how to prevent

Question

it.Preferably if it is working.WE have big ppl coming to our school and it has to be grand!PLs help me out

Answer 1

Global Warming is caused by Pollutions in the air. It can be prevented by not driving around as much and car pulling!

Answer 2

Check out Discovery Kids.Com  they have alot of cool stuff that can help.

Answer 3

The model which best represents the supposedly "proven" global warming would be a big steaming pile or bull manure  sculpted into the image of Algore.

Answer 4

Oil.

That's where a lot if the issues lay.

Gasoline

Plastics

Plastics encompass a huge number of things you probably wouldn't even think of. like the obvious, plastic, to things like clothing and food additives.

Perto chemicals is the trail you want to follow.

However you may want to shock your entire school by showing what the whole global warming scam is all about, don't get me wrong, the Earth is in crisis but there are people out there poised to make a lot of money off of "carbon credits" if everything goes their way.

Basically the whole issue of global warming is a way for niche businessmen to scam businesses out of money so they don't have to go green.

I am sure your school is looking for some cookie cutter Al Gore answer that leaves you with more questions than answers, if you use any of the ideas I have given you, you may not win but you may educate, it's up to you what is more important.

Answer 5

Global warming is caused by the Sun.  I don't know how you would propose placing limits on the Sun.

"In what could be the simplest explanation for one component of global warming, a new study shows the Sun's radiation has increased by .05 percent per decade since the late 1970s."

""Solar activity has apparently been going upward for a century or more," Willson told SPACE.com today. "

Answer 6

Talk about the CARBON CYCLE. It all boils down to the carbon cycle. Atmospheric CO2 has both natural and human causes; however, nature "recycles" more than a fair amount of CO2, whereas human do not "recycle" any CO2. The net result is increasing concentrations of atmospheric CO2 -- a greenhouse gas. If humanity can limit greenhouse gases from anthropogenic (man made) sources, then we can prevent further global warming.

Carbon dioxide is produced naturally here on Earth, by such means as animal respiration (or digestion, in the case of methane) and the decay of plant and animal matter.  This carbon is then naturally removed or “recycled” from the atmosphere, mostly through the process of photosynthesis, or plant respiration.  

For more then 10,000 years, since the end of the last ice age (yes! Planet Earth has had climate changes in the past, though not all of these changes have had the same cause) the carbon cycle has been relatively stable.  The amount of carbon dioxide that entered the atmosphere equaled the same amount of carbon dioxide that was removed and the overall atmospheric CO2 concentration remained constant, at about 280ppm.  

Climate change is about change.  Humans have upset the natural budget of the carbon cycle. We have accomplished this through certain activities such as energy production (burning fossil fuels release large quantities of CO2 into the atmosphere) and deforestation.  Humans are only adding carbon to the atmosphere, which is just half of the equation; mankind is not removing any carbon dioxide from the atmosphere.  In addition, deforestation reduces the amount of CO2 that nature is able to remove from the atmosphere.  

The next time someone argues that humans are only responsible for 5% of the atmospheric CO2, please mention the carbon cycle.  They probably just forgot.  Forgetting could be dangerous if they are talking about issues that are important.  Suppose that I was budgeting to save money for something real nice.  Suppose that I also only added up my incomes, but “forgot” to subtract my expenditures.  I would have a pretty misleading amount in my bank account by the end of the year, right?  

The atmospheric CO2 concentration has increased by about 35% since pre-industrialization times, and is now 383ppm.
