Transcript of climate change year 9

photo credit Nasa / Goddard Space Flight Center / Reto Stöckli Over the last century, human beings, by their actions, have greatly increased the amount of carbon dioxide in the atmosphere. Every time we drive a car, or use electricity from a coal-fired power, or heat our home with oil or gas, we produce carbon dioxide. High levels of this gas are turning the atmosphere into a heat-trap. Most scientists agree that the earth overall is becoming warmer. (This is called Global Warming.) They say that this is causing Climate Change i.e. a change in the climate everywhere. Weather is becoming more extreme; for example, storms are more frequent and more violent. There are more extremes of heat and cold. This climate change will accelerate if humans keep increasing the rate at which they produce carbon dioxide. Forests which could soak up carbon dioxide from the atmosphere, are being cut down to make quick profits. Climate Change As christians we should be concerned about this because God chose us to be stewards and to look after the world,we should be concerned about this because if we let this continue we will not be fulfilling our duty as stewards. As rising levels of carbon dioxide (Co2) rises so does the temperature this will cause the poles to melt, we don't stop this the water level will rise a considerable amount, easily rising above the level of small pacific islands. Many coastal cities in Northern America (U.S.A) will become inhabitable leading to the overpopulation of southern cities. It is the same for every where else, especially for poorer countries.It will led to floods and crop failures, millions will die. There are 4 easy ways we can reduce our carbon dioxide output. LI: To learn the meaning of climate change.
To find 4 ways of lowering our Co2 emissions.
To answer a worksheet with questions based on this power point. 1. You can try to walk to school or training or wherever you are going but if you have to use transport, use the bus. 2. Try to be energy efficient, try to turn off lights when no one is using them, try to hand wash or wind dry clothes during spring and summer, as washing machines and dryers use a lot of energy. 3. Waste buried in landfills produces methane, a poisonous gas. Keep stuff out of landfills by composting kitchen scraps and cut grass. Don't throw away bottles, cans or paper as it can all be recycled and used again, which is more economically friendly. 4. Try to eat organic food or food grown close to home ( like Glenavy potatoes), which hasn't been processed, since dairy and meat production alone accounts for 18% of pollution today. Affects of climate change
* Seasons are shifting
* Warmer temperature
* Changing landscapes
* Rising sea levels
* Heat related illnesses
* Stronger storms
*Increased risk of drought. Worksheet
What is climate change?
What are the effects of climate change?
What causes climate change?
What are the effects of the poles melting?
What effects will it have on humans and wildlife? 1. Climate change is a change in the climate everywhere. 2. The effects of climate change are* Seasons are shifting
Warmer temperature
Changing landscapes
Rising sea levels
Heat related illnesses
Stronger storms
Increased risk of drought. The Future Impact Coastal Areas: The sea levels will rise. Low lying coastline and islands will become submerged. People will have to evacuate their homes permanently. Urban Areas: More frequent heat waves and poorer air quality this will affect the old, the poor and people with breathing difficulties. Farming Community: More frequent heat waves and bursts of destructive rain will turn land into a desert or a scrub this will cause farms to be abandoned. Countryside: Streams, lakes and wetlands will dry up, Jobs in tourism will disappear. Hunting, skiing and boating will no longer be available. The Signs 1998 Was the warmest decade since AD 1000-2000 In May 2003 there were 384 tornadoes in one week in the mid-west of the U.S.A. This was a record. 2003: In New South Wales and Australia there was the worst drought ever. February 2004: Torrential flooding killed over 2000 in Haiti and the Dominic Republic. Cities under threat today of of flooding are Bangladesh and the Solomon Islands. 3. We can prevent climate change by walking instead of using the car, turning off lights when not in use, composting kitchen scraps and cut grass. 4.The thing that causes climate change high levels of Co2 turning the atmosphere into a heat trap. 5. The effects of the poles melting will be that the sea level will rise, submerging small pacific islands and many coastal cities will become swampy ghost towns. 6. The effects it will have is that the cities that have become inhabitables population will be evacuated to southern cities which will become overpopulated. The wildlife will die as their habitats will have been flooded/destroyed. The End By Cormac Dwyer
