Global warming

By Matthew and saeb Slide2

What is global warming

Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually

. The chart for global co2 emissions is to the left.Slide3

How global warming affects the u.s.a

Northeast.

 Heat waves, heavy downpours and sea level rise pose growing challenges to many aspects of life in the Northeast. Infrastructure, agriculture, fisheries and ecosystems will be increasingly compromised. Many states and cities are beginning to incorporate climate change into their planning.

Northwest.

 Changes in the timing of streamflow reduce water supplies for competing demands. Sea level rise, erosion, inundation, risks to infrastructure and increasing ocean acidity pose major threats. Increasing wildfire, insect outbreaks and tree diseases are causing widespread tree die-off.

Southeast.

 Sea level rise poses widespread and continuing threats to the region’s economy and environment. Extreme heat will affect health, energy, agriculture and more. Decreased water availability will have economic and environmental impacts.

Midwest.

 Extreme heat, heavy downpours and flooding will affect infrastructure, health, agriculture, forestry, transportation, air and water quality, and more. Climate change will also exacerbate a range of risks to the Great Lakes.

Southwest.

 Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.Slide4

How climate change

a

ffects ice glaciers

After existing for many millennia, the northern section of the Larsen B ice shelf in Antarctica -- a section larger than the state of Rhode Island -- collapsed between January and March 2002, disintegrating at a rate that astonished scientists. Since 1995, the ice shelf's area has shrunk by 40 percent.

According to NASA, the polar ice cap is now melting at the alarming rate of nine percent per decade. Arctic ice thickness has decreased 40 percent since the 1960s.

Arctic sea ice extent set an all-time record low in September 2007, with almost half a million square miles less ice than the previous record set in September 2005, according to the National Snow and Ice Data Center. Over the past 3 decades, more than a million square miles of perennial sea ice -- an area the size of Norway, Denmark and Sweden combined -- has

disappeared, that is 339,089 squared square mile.

Multiple climate models indicate that sea ice will increasingly retreat as the earth warms. Scientists at the U.S. Center for Atmospheric Research predict that if the current rate of global warming continues, the Arctic could be ice-free in the summer by 2040.

At the current rate of retreat, all of the glaciers in Glacier National Park will be gone by 2070.Slide5

How that affects sea level

Global sea level has already risen by 4 to 8 inches in the past century, and the pace of sea level rise appears to be accelerating. The Intergovernmental Panel on Climate Change predicts that sea levels could rise 10 to 23 inches by 2100, but in recent years sea levels have been rising faster than the upper end of the range predicted.

In the 1990s, the Greenland ice mass remained stable, but the ice sheet has increasingly declined in recent years. This melting currently contributes an estimated one-hundredth of an inch per year to global sea level rise.

Greenland holds 10 percent of the total global ice mass. If it melts, sea levels could increase by up to 21 feet.

How rising sea levels affect us

Sea level rising will affect you because the water will flood the land and can kill humans, animals, and destroy land marks. This is Florida with 3 meters of water risen, this hasn’t happened yet but it will eventually. Also scientists have predicted that sea level will rise 23 inches by 2100. Slide7

how will we reduce global warming

We will reduce global warming by using electric cars and the cars that use oil will be taxed, the tax rate will $3 for every 20 pounds of CO2 your car emits. Also if you have items that make air pollution you will be taxed depending on how air pollution it makes. There are electric 18 wheelers to transport items. For planes jet fuel will still be used but taxed, currently there are no electric cargo planes or passenger planes that can hold more than 5 people. So until we can make those planes, jet fuel planes will still be in use.Slide8

Where will the solar panels, wind mills, and kinetic tiles go?

In the u.s.a. solar panels will be in all of the deserts and wind mills will be in north Dakota south Dakota, Nebraska, Kansas, Oklahoma, Texas, Iowa, Missouri, Arkansas, Illinois, and Indiana. the kinetic tiles will be in subways, airports, colleges, and other places where a lot of people walk. Slide9

The energy sources we will convert to

We will convert to electricity. We will get the electricity by wind mills, solar panels, and kinetic tiles. Kinetic tiles are tiles that you step on and they create electricity. There are two ways kinetic tiles work. one way is

Piezoelectricity

When

the material is compressed

the atoms

press together enough to change the configuration of the electrons. When the pressure is removed the electrons return to their previous place. If the piezoelectric compounds are fitted with an auxiliary circuit though, the returning electrons can be captured and used to create a micro circuit.

The second way is Hydraulics

When

the series of hydraulic pistons are compressed they can force hydraulic liquid through the system creating pressure. That pressure is pushed through hydraulic lines and eventually stored in a pressure vessel known as an accumulator. The stored pressure is then ran through a motor or generator as needed producing electricity.Slide10

How will we pay for it

we will pay For it by each citizen (above 18) (if you make $50,000 or more) will be taxed $1 to the government and that tax will happen every year. and if that works that will be around $200,000,000 per year. There will also be a donation group and all of the money it raises will go to the government to fund the project. Also on slide 7 it said that we will tax things that make air pollution and that money will be used to fund this.Slide11

The changes you will see if you vote for our proposal

You will see lots of changes in the united states like most cars will be electric and the oil burning cars will be taxed. There would also be wind mills everywhere and solar panels in every desert or in a place with a lot of sun.Slide12

Should we have other countries involved

Yes, we will try to get all of Europe doing the same thing America will do. Then if they are on board we would talk to other countries like china and Russia and if they are on board then we will move to the middle east and then south America and these will be the areas that we will help. Once we have all the countries

i

nvolved the country leaders will have a meeting and talk about ideas on new ways to get clean electricity and stop global warming. The country that won’t be involved will be Africa because Africa doesn’t have enough money to help support this idea

and they don’t produce as much pollution as we do.Slide13
