WHAT –describe the type of the change that is occurring.

Global warming is one of the gravest threats facing wildlife today, and plants and animals around the country are in real danger of falling victim because their habitat is changing too rapidly for them to keep up. One of the animals that is really suffering is the Trout and Salmon.

WHERE – include more than one example (where possible) where climate change has had an impact.

Describe the location / distribution of these places and provide a map.

these places and provide a map.

• One place where climate change had and impact is in the Great Barrier Reef. The ocean bleaches more coral every year. A more acidic ocean makes coral weaker, so it can't grow properly or survive storms. Some areas are already dead and many more will follow. Animals that rely on the reef for shelter also suffer. By 2050, scientists predict that 95 per cent of existing coral reefs as seas become too warm and acidic. Reefs will be dominated by algae and no more coral.

WHEN – investigate when the changes started to occur and how long it has been

happening. Use a table or statistics if possible

•Australia's Great Barrier Reef could lose 95 percent of its living coral by 2050. The Great Barrier Reef is the world's largest reef, stretching more than 2,300km also, the Great Barrier Reef is home to over 1,500 species of fish and 400 species of coral making it one of the most important marine ecosystems on Earth. The first changes was in 1979 were first coral bleaching on record occurred. So this problem has been occurring since 1979, if wee don't be careful by the time its 2050 the whole of the great barrier reef will be gone.

•Great Barrier reef National Park to see figures on when.

HOW / WHY – explain the physical processes that have taken place that caused the impact on the physical or human environments. Use

diagrams where possible to support your explanation.

• The great barrier reef is dying because of pollution and Global Tourists and recreational fishermen are particularly damaging to the Great Barrier Reef, as they drop their plastic bags and other non-environmentally friendly items into the water. It is generally accepted that it would take a mere couple of degrees of warming of sea temperatures to wipe out some species on the Reef.

• One of the most visually dramatic effects of climate change on corals has been bleaching. When the ocean warms, the oxygen content reduces, and corals become bleached. The heat affects the tiny algae which live symbiotically inside the corals and supply them with food. The heat stress damages the algae and in consequence leads to coral death.

WHAT – describe and explain the negative and possible positive impact

on the physical and human environment. Use pictures and diagrams to support your work.

• Warming and it could end up costing the economy $8 billion and more than 12,000 jobs by 2020 .

EVALUATE – how serious is this problem for the physical and human

environments in the long term and why? Are there any positive aspects

that may eventuate?

Conclusion: sum up your findings and give your opinion on the answer to the

question “what is the evidence?”

PREDICT – what will be the outcome if change continues? Use statistics,

diagram or map if possible to support your answer.

Positive Negative

More than 12,000 jobs by 2020 .

Warming and it could end up costing the economy $8 billion.
