LEARNHOW TOHEALTHE WORLDIntroductionIn 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 criteria focusing on five key themes; Fact vs Fiction, Cause and Effect, Supporting Evidence, Preventative Actions and Resolution Outcomes.Craig Barnsley - Fiona Pidgeon - Tami Jones

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 19th century, has risen 0.85oC and has continued to do so since the middle of the 20th century (since greenhouse gases have increased).

Supporting Evidence

The evidence for climate change is overwhelming. On average, the global temperature has increased 0.6oC 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: CO2 gases are the main contributing factor towards climate change. It is important to consider a wide range of sources when understanding climate change.

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.greenFOR THE FUTURE

LEARNHOW TOHEALTHE WORLDClimate ChangeResolution Outcomes

At the 22nd Annual meeting of theAsia-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.

LEARNHOW TOHEALTHE WORLDMelting Ice GlaciersEverywhere 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.

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.

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.

LEARNHOW TOHEALTHE WORLDMelting Ice GlaciersWhen 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).

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.

LEARNHOW TOHEALTHE WORLDRising Ocean TemperaturesIn 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.

LEARNHOW TOHEALTHE WORLDRising Ocean TemperaturesSupporting 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)

Preventative Actions

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).


LEARNHOW TOHEALTHE WORLDRising Ocean TemperaturesResolution 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).

LEARNHOW TOHEALTHE WORLDRising Ocean TemperaturesCause 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 unlikelythat global climate change of the past 50 years can be explained without external forcing andvery likelythat 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).

LEARNHOW TOHEALTHE WORLDConclusionGlobal 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 0.6oC 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.
