this presentation we will outline some of the elements of Global
warming in particular; Climate Change, Melting Ice Glaciers and
Rising Ocean Temperatures. This will be assessed against a research

http://climate.nasa.gov/evidence) Cause and Effect There are a
variety of causes that contribute to climate change but more
significantly, it is the gases produced by human activity as well
as water vapour production. The global average temperature, since
the late 19 th century, has risen 0.85 o C and has continued to do
so since the middle of the 20 th century (since greenhouse gases
have increased). Supporting Evidence The evidence for climate
change is overwhelming. On average, the global temperature has
increased 0.6 o C with the 12 warmest years on record occurring
since 1998. But also changing are the patterns in rainfall, snow,
droughts and storms. This in turn has also had effects on plant and
animal behaviour. Fact vs Fiction Climate change is supported by
many facts and a lot of fiction. Fact: Climate change is, as
arguably agreed by scientists, a direct result of human activity.
Fiction: CO 2 gases are the main contributing factor towards
climate change. It is important to consider a wide range of sources
when understanding climate change. g reen FOR THE FUTURE

Supporting Evidence The evidence for climate change is
overwhelming. On average, the global temperature has increased 0.6
o C with the 12 warmest years on record occurring since 1998. But
also changing are the patterns in rainfall, snow, droughts and
storms. This in turn has also had effects on plant and animal
behaviour. Preventative Action In Australia, the Government has
investigated various preventative actions that can be considered to
minimalise further global warming. The Government is looking at
improved agricultural and water management practices as well as
sustainable mining, manufacturing, architecture, business and
financial services and tourism. There also needs to be further
concentration on climate change measures for individuals and this
will come about as a result of further media campaigns. Other ways
include reducing emissions by using less, using something else
which is less harmful and also looking at how we can capture and
store those emissions. g reen FOR THE FUTURE Global Surface

Resolution Outcomes At the 22nd Annual meeting of the Asia-Pacific
Parliamentary Forum, the Australian delegation wrote a draft
resolution (3.1) for the cooperation to face climate change. This
draft resolution calls upon all signatories to consider
policymaking in the area of climate change as well as move climate
change to the forefront of their agendas and budgets. There is also
a call to implement innovative models of sustainable development.

Craig Barnsley Tami Jones Fiona Pidgeon Group 5 - Learning and
Communicating Online LEARN HOW TO HEAL THE WORLD Melting Ice
Glaciers Supporting Evidence Everywhere on Earth ice is changing.
The famed snows of Kilimanjaro have melted more than 80 percent
since 1912. Glaciers in the Garhwal Himalaya in India are
retreating so fast that researchers believe that most central and
eastern Himalayan glaciers could virtually disappear by 2035.
Arctic sea ice has thinned significantly over the past half
century, and its extent has declined by about 10 percent in the
past 30 years. NASA's repeated laser altimeter readings show the
edges of Greenland's ice sheet shrinking. Fact vs Fiction Spring
freshwater ice breakup in the Northern Hemisphere now occurs nine
days earlier than it did 150 years ago, and autumn freeze-up ten
days later. Thawing permafrost has caused the ground to subside
more than 15 feet (4.6 meters) in parts of Alaska. From the Arctic
to Peru, from Switzerland to the equatorial glaciers of Man Jaya in
Indonesia, massive ice fields, monstrous glaciers, and sea ice are
disappearing, fast. Spring ice break up in river [Image]. Retrieved
from https://ecogirlcosmoboy.wordpress.com/category/communicat
ion/science-communication/ Cause and Effect As the Earth system
warms due to rising levels of greenhouse gases in the atmosphere,
observations show that land-based glaciers are melting fast in many
places around the world - in the United States, Europe, South
America, and Asia. Because of ice-albedo feedback, as ice melts,
albedo rises, producing further warming and faster melting. Model
predictions indicate that the remaining large glaciers in Glacier
National Park will be gone by 2030. g reen FOR THE FUTURE
Slide 9
Craig Barnsley Tami Jones Fiona Pidgeon Group 5 - Learning and
Communicating Online LEARN HOW TO HEAL THE WORLD Melting Ice
Glaciers Preventative Action When temperatures rise and ice melts,
more water flows to the seas from glaciers and ice caps, and ocean
water warms and expands in volume. This combination of effects has
played the major role in raising average global sea level between
four and eight inches (10 and 20 centimeters) in the past hundred
years, according to the Intergovernmental Panel on Climate Change
(IPCC). Actions on the part of industrial nations to curb
greenhouse gas emissions will set an example for rapidly developing
nations and will be an important step toward mitigating the impacts
of ice sheets on future sea level rise and humans worldwide

Resolution Outcomes The Greenland, Alaskan and West Antarctic ice
sheets together hold about 25% of the fresh water on the planet.
The effects of the collapse of either ice sheet would be huge. Once
you lose one of these ice sheets, there's no putting it back for
thousands of years, if ever. If they disintegrate, sea level could
rise nearly 20 metres, possibly in only one decade. This would
swamp most cities and ports, as well much of the best agricultural
land, where over 6 billion people inhabit. Similarly the western
Antarcticas mass is disappearing at about 240 cubic kilometres per
year. Depletion of ozone is adding to this problem for it has
encouraged hotter winds to flow across the Antarctic.

Communicating Online LEARN HOW TO HEAL THE WORLD Rising Ocean
Temperatures In spite of all the difficulties, Lyman et al are able
to demonstrate a robust warming of the globe between 2003 and 2008
(Lyman & Good et al., 2010). However this data is only measured
to a depth of 700 meters. A reappraisal of the messy data on
upper-ocean heat content for 19932008 provides clear evidence for
warming. But differences among various analyses and inconsistencies
with other indicators merit attention (Trenberth 2010). Fact vs
Fiction Is global warming really causing the ocean temperature to
rise? There are many inconsistencies in the data to support rising
ocean temperatures due to the enormous size of the ocean, and the
amount of naturally occurring variability caused by whether
phenomena. Figure 1: Changing heat content of the global ocean,

Craig Barnsley Tami Jones Fiona Pidgeon Group 5 - Learning and
Communicating Online LEARN HOW TO HEAL THE WORLD Rising Ocean
Temperatures Supporting Evidence The amount of information
available in regards to Rising Ocean Temperature caused by climate
change is extensive to say the lease. Organisations, Governments,
and international councils on climate change are researching and
discovering new information daily. The most objective evidence is
outlined by the International Panel on Climate Change. Because of
its scientific and intergovernmental nature, the IPCC embodies a
unique opportunity to provide rigorous and balanced scientific
information to decision makers. By endorsing the IPCC reports,
governments acknowledge the authority of their scientific content.
The work of the organization is therefore policy-relevant and yet
policy-neutral, never policy- prescriptive. (Ipcc.ch, 2014) Average

Continued emissions of greenhouse gases will lead to further
climate changes. Future changes are expected to include a warmer
atmosphere, a warmer and more acidic ocean, higher sea levels, and
larger changes in precipitation patterns. The extent of future
climate change depends on what we do now to reduce greenhouse gas
emissions. The more we emit, the larger future changes will be
(Epa.gov, 2014).

Temperatures Resolution Outcomes There is an overwhelming need for
international cooperation to reduce the rising ocean temperatures,
and climate change as a whole. As new technological and scientific
methods are discovered, a shared and collaborative approach will
lead to the best outcomes. A basic problem here is that cooperation
is needed among a very large group of unrelated individuals, in
effect the entire human population (Gsottbauer & Van Den Bergh,
2012). Tropical Ocean Temperatures over the past 3.5 Billion Years.

Slide 13
Craig Barnsley Tami Jones Fiona Pidgeon Group 5 - Learning and
Communicating Online LEARN HOW TO HEAL THE WORLD Rising Ocean
Temperatures Cause and Effect The cause of Rising Ocean Temperature
can be attributed to many things, however The observed widespread
warming of the atmosphere and ocean, together with ice mass loss,
support the conclusion that it is extremely unlikely that global
climate change of the past 50 years can be explained without
external forcing and very likely that it is not due to known
natural causes alone (Pachauri & Reisinger, 2008). The minor
increases of 0.1c per year may seem like an insignificant rise,
however even a small change in water temperature can be detrimental
to marine life, reproduction and feeding patterns to name just a
few (Sanctuaries.noaa.gov, 2014). Changes in coral reef [Image].

warming is not just an issue for industry, but for individuals and
governments alike around the globe. This presentation has
demonstrated the impact of climate change across the globe with
global temperatures having risen 0.6 o C and governments across the
world committing to changing practices. Melting glaciers have been
discussed with evidence demonstrating that they are disappearing
fast. We have also seen the ever changing effects on the globe to
ocean temperatures as a result of global warming. Click on the
