Question: How does burning of
fossil fuels affect our climate change?
Global: Where/What will it cause. (Storm, flood,
droughts etc)/ temp change/
Asia-Pacific carbon emissions are predicted to increase by 85% in the
next two decades. Already half of global mercury emissions come from Asian
fossil-fuel power plants.
Burning of fossil
fuels will release more CO2, which will cause more warming which will cause Ice
glaciers to melt, which will cause rise of sea level. (Venice Italy)
Scientific research indicates sea levels
worldwide have been rising at a rate of 0.14 inches (3.5 millimeters) per year
since the early 1990s. The trend, linked to global warming, puts thousands of
coastal cities, like Venice, Italy, (seen here during a historic flood in
2008), and even whole islands at risk of being claimed by the ocean.
Ice loss from
Greenland and West Antarctica:
As with glaciers and the ice caps, increased
heat is causing the massive ice sheets that cover Greenland and Antarctica to
melt at an accelerated pace. Scientists also believe meltwater from above and
seawater from below is seeping beneath Greenland's and West Antarctica's ice
sheets, effectively lubricating ice streams and causing them to move more
quickly into the sea. Moreover, higher sea temperatures are causing the massive
ice shelves that extend out from Antarctica to melt from below, weaken, and
break off.
Which places will this effect the most? Eg. A
place where burning fossil fuels is done very commonly.
China will be affected because its one of the
top country that burns fossil fuels.
1 power station is built a week.
What is it effecting (biodiversity, peoples
health, economy)
In the United States, 23,600 deaths a year are attributed to air
pollution from power plants. The burning of coal is also responsible for some
554,000 asthma attacks, 16,200 cases of chronic bronchitis, and 38,200
non-fatal heart attacks annually.
Mercury emissions from coal-fired power plants cause acid rain, which
costs some US$90 billion every year in the Asia Pacific region alone.

What effects does it have/had or will have.
(Weather)
Temperature Rise
Compared with the
1986-2005 average of 23.3ºC, the annual mean temperature in Hong Kong in the
late 21st century (2091-2100) is expected to rise by 3-6ºC. As for extreme
weather, the study by Hong Kong Observatory shows that the annual number of hot
nights (days with a minimum temperature of 28ºC or above) and very hot days
(days with a maximum temperature of 33ºC or above) in summer will increase. On
the other hand, the annual number of cold days in winter (days with a minimum
temperature of 12ºC or below) will continue to drop.
Sea Level
Rises
An analysis of the sea
level records for more than 50 years of the Victoria Harbour shows that on
average, the mean sea level in the Victoria Harbour has risen at a rate of
2.9 mm per year during the period 1954 to 2013. The trend is similar to
that over the South China Sea as measured from satellites using remote sensing
techniques from 1993 to 2005.
What is it affecting? (Biodiversity, people’s
health etc.)
Burning of fossil fuels is effecting our green house
(HK)
Human activities cause an increase
in ambient concentration of greenhouse gases, mainly through burning of fossil
fuels. The greenhouse gases act like a blanket in the atmosphere, keeping the
sun’s energy from radiating back to space, and resulting in a rise in
temperature globally – a phenomenon commonly called global warming.
Personal: What do I
contribute? (Use a lot of electricity)
How can I change what I do?
How will what I do
help the environment and climate change?
What I think about
climate change and global warming.
Global warming is a
topic that has a large affect on our world in many ways. Every human being
contributes to affect our climate and environment on a daily day basic. There
are many things that I do which affect our environment, such as leaving the tap
water open, leaving my AC on, toasting my bread, which all use energy. Energy
is made from burning fossil fuels, which lead to severe weather conditions. I
can make a change by using energy efficient light bulbs, use a regular
toothbrush rather then an electric one and try consuming less. If I use less
electricity, less energy will need to be made which will decrease the amount of
burring fossil fuels. Decreasing the amount of burning fossil fuels will be
beneficial because less CO2 will be made which wont effect our greenhouse as
much. I can also make a big change to global warming by consuming less. If I
consume less, I’m asking for less products to be made which help reduce energy,
and deforestation, which play a large role in global warming. In my religion we
believe that G-D created the world in six days and rested on the sevens day
which is Saturday. Through out the Jewish history most Jewish families like my
family rest on Saturday, which means that we don’t use any electricity such as
turning on the lights or driving. Shabbat is a great day for us to be with our
families as well as to save our planet.
Global warming:
In the last decade he
has been thinking if his contribution to global warming would of changed the
worlds situation right now.
Temperatures rose by
0.6 degrees Celsius (average) this is a small different but actually has a
large effect. Eg. Seas temperature rose by 3 degrees Celsius due to this
change. (causes ice to melt)
Ice melting causes
seals to die which means polar bears cant go hunting for them to feed their
babes.
Polar bears are
getting hungrier because the ice melt which effects their health.
Introduction:
What is global warming. (diagram)
Global warming is the rise of the earths temperature due to the increase of C02 emission. C02 emissions have been at its highest in the past 600 years which plays a large role in global warming. When CO2 gets released into the air, it gets trapped in the upper atmosphere, creating a blanket which stops heat from leaving our planet. Human beings also have a large contribution to global warming in many ways. Humans use a lot of electricity, therefore more fossil fuels have to be burnt. Humans are also knows as consumers, therefore deforestation has to be done more often. These things are all done for the beneficial of humans but actually have a huge knock on effect. These actions are completely destroying our planet and are leading to horrible possible scenarios. Global warming is worrying many people due to all the predictions that are made for the future. Global warming can be stopped if all humans start caring for our world. There are plenty of ways, and solutions to prevent global warming, therefore we need to work together and keep our world safe for the next generations. Global warming causes severe weather condition which has a big effect on our climate change.

As temperature rise,
Ice melts which causes sea level to rise, which causes seas to expand.
Reduces land and at
the same time are population is increasing which is a problem.
As seas temperature
increases this causes hurricanes.
CO2 prevents the suns
light not able to go back to space which causes warming.
Co2 is needed due to
many things like Photosynthesis.
