Climate change
- 2. Climate change is the change in the earth’s weather conditions over a long period of time. Changes in the climate has a tremendous effect on us and other organisms. It effects food production, water availability, wildlife and health.
- 3. Physicists should use more efficient system. Biologists could help protect wildlife by continuing to research and observe them so they can specifically determine how climate change has an effect on them. Chemists could help deal with oil spills by creating compounds to neutralize the effects oil has on the environment.
- 4. Some politicians require the use of carbon dioxide and fossil fuels for industrialization purposes. Which builds a strong economy but has a bad impact on the environment. Politicians could create laws for the better of the environment by limiting the percentage of wasteful industrialization. As well as switch into better and more efficient systems. Society wants oil because it makes a powerful economy. Oil is a limited resource, therefore it is high in value. The best thing to do would be to get off oil and use a different resource like wind power or electricity.
- 5. In order to stabilize the concentration of greenhouse gases, the emissions would have to stop increasing. World-wide investments will have to be put in cutting down technologies and in new energy sources. The longer we wait to make a difference in emission reduction the harder it will be to solve the issue, and the more of a risk there is in severe climate change impacts.
- 6. The climate is getting warmer in the far north regions which is effecting animals like polar bears and their adaptations. Risks of extreme weather conditions such as heat waves, heavy rainfall, over floating and forest fires. Sea ice, seasonal snow cover, glaciers , ice caps, permafrost and river and lake ice are all indicators climate change. Sea ice thickens has increased and the annual maximum ice area has shrunk less rapidly.
- 7. Quick changes caused by global warming are taking place in the Arctic that threaten the survival of this species. Global Warming is melting the polar ice caps which is making it hard for polar bears to hunt prey. In the Arctic ice cap continues to melt and if it keeps happening and if we don’t do something about it, the polar bears will become too thin to reproduce and they will become extinct by the end of this century.
- 8. Transportation: To encourage people to use public transit more Cons Pros -less privacy -Reduces the amount of pollutions and -less space greenhouse gases emission -More waiting time Riding a bus is 79 times safer than riding -In winter its harder to wait for long a car because it is cold -Unsanitary -Studies have shown people who used -More risks in flu seasons public transport are healthier because of the amount of walking it takes to walk to and from bus stops. -According to a study done in the US families that use public transport can save up to $6 200 annually by using public transport.
- 9. Energy: Development of renewable energy sources that do not emit greenhouse gases. Pros Cons -Reduces greenhouse gas emissions. -it is difficult to generate large quantities -Require less maintenance. of electricity. -Better for the environment. -It would be easier to do in Yellowknife - Renewable energy usually relies on the because it is a small town. weather for its source of power. Hydro generators require rain to fill dams to supply water. Wind turbines need wind to turn the blades, and solar panels need sunshine to collect heat and make electricity. -The current cost of renewable energy technology is quite high.
- 10. For our transportation we can develop a new public transit system that includes more bus stops, more buses, more seats to carry more people, all day transit timings, and less time consuming bus schedules. For the development of renewable energy source instead of the use of fossil fuels we could use electricity. This way we will never run out of the energy source, and its way better for the environment. We could use electric cars, this will save us lots of oil and money. It’s a win win situation!
