To pursue knowledge and practices that can lead to more environmentally friendly and ecologically responsible decisions and lifestyles, which can help protect the environment and sustain its natural resources for current and future generations
Intergovernmental Panel on Climate Change (IPCC) scientists believe that it is very likely (greater than 90 percent chance) that most of the warming we have experienced since the 1950s is due to the increase in greenhouse gas emissions from human activities.
Greenhouse Effect a natural occurrence that helps regulate the temperature of our planet Like a greenhouse Global Warming an average increase in temperatures near the Earths surface and in the lowest layer of the atmosphere.
Carbon Dioxide Nitrogen oxide Methane Water vapour ozone
Volcanoes Solar output Earths orbit around the sun
Burning fossil fuels Conversion of forest into agriculture
Average global temps could get rise 1 to 6.5º C in this century What could happen if it increased to each of these degrees? Write down at least 2 notes from this clip Lets see @ 6 degrees6 degrees
National Geographic Channel February 24th at 7 p.m. The documentary, featuring British author Mark Lynas and other notable climate experts, explores what effect each rise of 1ºC could have on the world and what must be done to reduce the threat. Some predictions include: At 2ºC higher: Greenland's glaciers and some of the lower lying islands begin to disappear. At 3ºC higher: Ice would no longer be found in the Arctic during the summer months, the Amazon rainforest would suffer a devastating drought, and extreme weather patterns would become frequent. At 4ºC higher: Oceans rise dramatically causing extreme flooding. At 5ºC higher: What scientists call the "twilight zone" of climate change, temperate regions could become uninhabitable, leading humans to battle each other for the world's dwindling resources. At 6ºC higher: Scientists call this the "doomsday scenario" because oceans become marine wastelands, deserts expand and catastrophic events become commonplace.
Fossil fuels A hydrocarbon deposit, such as petroleum, coal, or natural gas, derived from living matter of a previous geologic time and used for fuel. Non-renewable resources
Renewable Resources metal water wind Sun (solar) wood air Can be continually reproduced
Which population is not negatively effected by the loss of water? What will happen to the squirrels if this continues? When did the rabbits become extinct? Why? Mice They will eventually become extinct In 2004, the pollution level was to high and quality was to low for the rabbit population
What would happen if pollution stopped? If the pollution leveled off, what would happen to the population and environment? a. it would go into extinction b. a health population c. no long-term change in the environment. The squirrel population would increase and the mice populations may decrease
B06 Unifying Concepts Form A P. 137-138 # 1-7 After the CRT, Take out your Chemistry of Life Worksheet
What did you learn about how humans can impact the earth? Was there something you didnt know about renewable or biodegradable products? If so what was it? When you hear about the chemistry of life, what do you think about it?
