Transcript of Climate Change
Climate is the average pattern of weather in a set place. Climate change is the change of the weather patterns in a set period of time.
What Causes Climate Change?
What are the Consequences?
The Greenhouse Affect
The greenhouse affect is when greenhouse gasses in the atmosphere absorb the suns heat and reflects it back into the earth, while some of the energy reflects back into space. This is essential to keeping the earth warm.
We contribute to the amount of greenhouse gasses in the atmosphere by driving cars, using factories and even farming cows
The problem is we are pumping
greenhouse gasses into the atmosphere. This could cause global temperature rises and could lead to all sorts of problems.
And Global Warming
Many things cause the climate of the earth to change. The sun drives the whole weather system of the earth so it would be reasonable to think that the sun might affect the climate. Since 1750 the energy of the sun has never stayed constant.But most scientists think that its the Greenhouse Affect that is driving climate change.
Although C02 can be found naturally it has been rapidly increasing within our atmosphere, especially onwards of the 1800s.C02 is one of the major Greenhouse gasses effecting the world.
Shrinking of Ice Sheets
Is There Any Evidence?
There is allot of evidence to support that Climate Change is happening. The sea level has risen by 17 centimeters
Greenland and antarctic ice sheets have lost 150 to 250 cubic kilometers of ice per year since 2002!
Climate change will affect the world in different ways in different places. The rise in temperature could completely melt the polar icecaps. This would
then cause the sea level to rise, possibly destroying many cities, towns and the flooding of crops. In Africa droughts are almost certain, many people thirst and hunger as many crops will fail as well. In North America flooding is likely from the melting of compacted snow, heat waves will be more likely, causing vast negative health benefits. To summarize
global warming will have immense negative affects and rare positive effects on the earth.
The UK could be affected in several ways. Extreme weather could be a very real possibility, many towns may be flooded. A hotter climate may mean that the UK could house many new insects, deadly insects. Farmers fear that some may eat crops and may be a huge problem for agriculture in the UK. Scientists believe that some parasites and disease carrying insects could live in the UK, this would lead to a substantial rise in insect transmitted diseases and thousands of deaths. Drought may also be a possibility as the warmer climate could evaporate key
reservoirs in the UK. To end on a lighter
note it may be possible that the UKs
wine industry might explode from
the warmer weather.....so we
Stop Producing Greenhouse Gasses.
Greenhouses gasses are the source of human made climate change. By cutting sown on the amount we produce we may slow down or even stop man-made climate change.
Use Electric transport and eat lab grown meat
Transport produces 28% of the worlds greenhouse gasses, by swiching to clean transport we can cut down on the amount of greenhouse gasses produced. Agriculture is responsible for 8% of greenhouse gasses mostly due to the methane produced by cows. In the future we may be forced to eat lab grown meat as it produces no greenhouse gasses and is more
Use renewable sources
Using renewable and clean sources of power will cut the amount of Greenhouse gasses produced. Coal is one of the biggest producers of greenhouse gasses on the world, in total electricity is responsible for 33% of the worlds greenhouse gasses.
How Do We Stop It?
