Global Warming [ causes, effects and resolutions ]



Global Warming

Causes : Global warming is a problem of too much carbon dioxide in the atmosphere. Because people burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere.

Effect : The effects of rising temperatures aren’t waiting for some far-flung future. he heat is not only melting glaciers and sea ice, it’s also shifting precipitation patterns and setting animals on the move.Some impacts from increasing temperatures are already happening.

  • Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.
  • Sea level rise became faster over the last century.
  • Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.
  • Precipitation (rain and snowfall) has increased across the globe, on average.
  • Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees.
  • Because of the high temperature, people have to open the fan or air conditioner so people make more global warming agian
Resolution:
Boosting energy efficiency The energy used to power, heat, and cool our homes, businesses, and industries is the single largest contributor to global warming. Energy efficiency technologies allow us to use less energy to get the same or higher level of production, service, and comfort. This approach has vast potential to save both energy and money, and can be deployed quickly.
Greening transportation The transportation sector's emissions have increased at a faster rate than any other energy-using sector over the past decade. A variety of solutions are at hand, including improving efficiency (miles per gallon) in all modes of transport, switching to low carbon fuels, and reducing vehicle miles traveled through smart growth and more efficient mass transportation systems.
  • Revving up renewables Renewable energy sources such as solar, wind, geothermal and bioenergy are available around the world. Multiple studies have shown that renewable energy has the technical potential to meet the vast majority of our energy needs. Renewable technologies can be deployed quickly, are increasingly cost effective, and create jobs while reducing pollution.
  • Phasing out fossil fuel electricity Dramatically reducing our use of fossil fuels especially carbon-intensive coal is essential to tackle climate change. There are many ways to begin this process. Key action steps include: not building any new coal-burning power plants, initiating a phased shutdown of coal plants starting with the oldest and dirtiest, and capturing and storing carbon emissions from power plants. While it may sound like science fiction, the technology exists to store carbon emissions underground. The technology has not been deployed on a large scale or proven to be safe and permanent, but it has been demonstrated in other contexts such as oil and natural gas recovery. Demonstration projects to test the viability and costs of this technology for power plant emissions are worth pursuing.
  • Managing forests and agriculture Taken together, tropical deforestation and emissions from agriculture represent nearly 30 percent of the world's heat-trapping emissions. We can fight global warming by reducing emissions from deforestation and forest degradation and by making our food production practices more sustainable.
  • Exploring nuclear Because nuclear power results in few global warming emissions, an increased share of nuclear power in the energy mix could help reduce global warming but nuclear technology poses serious threats to our security and, as the accident at the Fukushima Diaichi plant in Japan illustrates to our health and the environment as well.
  • Developing and deploying new low-carbon and zero-carbon technologies Research into and development of the next generation of low-carbon technologies will be critical to deep mid century reductions in global emissions. Current research on battery technology, new materials for solar cells, harnessing energy from novel sources like bacteria and algae, and other innovative areas could provide important breakthroughs.
  • Ensuring sustainable development The countries of the world from the most to the least developed vary dramatically in their contributions to the problem of climate change and in their responsibilities and capacities to confront it. A successful global compact on climate change must include financial assistance from richer countries to poorer countries to help make the transition to low-carbon development pathways and to help adapt to the impacts of climate change.

Symbiosis

Symbiosis
Member : Mimi Ohm Fook
Mimi : A little formatting (very little and make it harder)
Ohm : Information and writting
Fook : Planning, decorating, formatting and pictured
 My group planed is plan by me. At first, Mimi wanted to do in Canvas but Ohm and me taught that work in google docs is easier so we made another one in google docs. But Mimi didn't do anything and she came in to change the fronts that me and Ohm were already type so the work is discodered. She still open canvas and we had to say close canvas and open the docs. The deside of Mimi wasn't the same as our deside but she didn't do it and say why we did so .... that opposite to her deside. 
I think Ohm's advantage is responsible. He know the time that he has to work. But his cons is the times, he doesn't has enough time because Ohm's house is so far to school.
I think Mimi's advantage  is the imagine she has the good design but her design doesn't paste enough information. But her cons is too decorating, didn't sloppy and if she has to do the thing that she doesn't want to do she will not doit or do just a little bit.

My favorites

My favorite activity/topic scientific method. This topic is important because it's the first thing that we have to know if we don't know it, we can't do the experiment to test anything that we want to know.
My least favorite activity/topic is make the observation because its very hard to find the observation of something that we already know.

Last conclusion with fish lab
1.  What do you think kills the fish/shrimp--oxygen or temperature of water,  why?
I think oxygen kills the fish/shrimp because it doesn't has enough oxygen.
2.  Did you find anything interesting in the lab?
When many bottles have fungus and died fish/shrimp, the lab is very smell.
3.  what other things could kill the fish? 
I think fungus killed the fish because they will rid the oxygen.

Fish and Shrimp
Hypothesis : The shrimp can't be leave for a longtime but the fish can leave longer than.
1. Why do you think your fish lived or died?
I think my fish lived because my fish is strong and my plants can take a sunlight so it can make the oxygen for fish.
2.  Groups with fish that are alive, how are their bottles different from yours?
I think my bottle different from another group because my bottle have a little bit yellow
3.  If you had to do it again, what would you change to keep your fish alive?
For now, my fish lived but I think how to make it live longer I have to change the water for 1 weeks and I have to take it on the place that have sunlight
