Global Warming
&
What is it? Global warming is when the green house gases like carbon dioxide, water vapour, nitrous oxide and methand trap heat and light from the suin in the earth’s atmosphere and cause the Earth to heat up (temperature rise). It happens because we human uses car, burns fossei fuels, not recycling and many more for the daiy life of ours but on the other side the pollution that we made goes up into the air and got trap in the atmosphere. What comes up next is so many uncountalbe problems that is late to be fixed.
Species at risk around the world Scientists predict that global warming could contribute to the mass extinction of wild animals in the near future. An overheating world is creating a big change in climatic conditions and this can harm the delicate ecosystems in which species live. Threatened species can already be found all over the world.

Climate changes
A
nimals and plants all around the world is suited to cooler climate than the climate now, so most of the species will have to move to upper hill or pole wards. This process has been observed in many places such as in the Alps, in mountainous Queensland in Australia, and in the misty forests of Costa Rica. The impacts on species are becoming so significant that their movements can be used as an indicator of a warming world. They are the silent witnesses of the rapid changes being inflicted on the Earth.
Animal’s
China
The giant panda’s future remains uncertain due to a number of threats. Its forest habitat in the mountainous areas of south-western China is fragmented, and giant panda populations are small and isolated from each other. Bamboo, the panda’s staple diet, is also part of a delicate ecosystem that could be affected by the changes caused by global warming. Poaching too remains an ever present threat, with only 1,600 individuals left in the wild.
Australia
In Africa, elephants face many problems after their living space had shrunk which brings them more frequently into conflict with humans. Elephants will have trouble on escaping from global warming which have affects on their habitat including longer dry period.
Climate change is affecting home range, abundance and breeding cycles of many of Australia’s frog species. Since frogs rely on water to breed, any reduction or change in rainfall could reduce frog reproduction. Higher temperatures contribute to the drying out of breeding pools, and as a result, to the deaths of tadpoles and eggs. Drier conditions also cause adult frogs to die, due to increased rates of internal water loss through their permeable skin.
Canada
Africa
The polar bear could extinct because of the global warming which is increasing the pace of it. Experts believe that the Arctic sea ice is melting at a rate of 9% per decade which is ruining the polar bear’s habitat where it always live on and may cause polar bear to extinct.
World India
Experts estimate there are as few as 3,200 tigers left in the wild, due to poaching, the loss of their habitat and depletion of the tiger’s natural prey. Hunters, traders and poor local residents use the forest for subsistence, directly competing with the tiger. Some of the largest remaining areas where tigers occur are the mangrove forests of India. The projected rise in sea levels could cause these living spaces of the tiger to vanish altogether.
Indonesia
Asia’s only ape, the orangutan is in a deep trouble. Its last remaining strongholds in the rainforests of Indonesia are being threatened by a range of pressures, including climate change, putting the animal at risk of extinction within a few years. With global warming increasing the pace and the frequency of droughts, bushfires are occurring more often especially in the orangutan living space.
South America
Sea turtles lay their eggs on Brazilian beaches, which are threatened by rising sea levels. Also if the climate changes it will threaten the offspring of the sea turtles because cooler temperature produce male offspring, while the warmer temperature produce female offspring. So now the weather had change to a warmer climate which it’s reducing the number of male offspring and seriously threatens the turtle population.
America
The North Atlantic right whale is one of the most endangered of all large whales, with a long history of human exploitation. Since warming waters contain less plankton for whales to feed because of the fluctuation of the weather. Between 300 and 350 individuals still exist, with little hope of population growth.
List of
E ndangered
International Union for the Conservation of Nature (IUCN) listed 9 animals which includes 1 plant that was one of the most affected species by the weather changes and global warming. Most of them are arctic animals.
Ringed Seals The Ringed Seals now must shift their ranges further north in order to find ice on which to raise their young. Stag horn Corals, The Stag Horn Corals whose
The Emperor Penguin The Emperor penguin might face food shortages because of a reduction in shelf ice under which the bird hunts for the shrimp-like krill on which it feeds. Also when the ice started to melt because of global warming, it means that there will be smaller breeding areas for the penguins. The Beluga Whale The Beluga Whale faces increased human intrusion into its habitat due to reduction in the ice that previo
ANIMALS Salmon, The Arctic Fox The Arctic Fox have to faces competition from red foxes that are now able to expand their range into the tundra because of the warmth of the weather which makes ice melt (global warming). Clownfish, Clownfish was threaten by how the ocean have a lot of acidification which affects their sense of smell, so it will lead the clownfish to suffer to find their prey to eat and protecting them self form predators. Leatherback Turtle, The reproduction is being affected by the rising temperatures of the beach sand in which it lays its eggs. Warmer temperatures cause dramatic
Salmon suffer from the fact that warmer water temperatures deplete the oxygen content in their breeding streams and rivers.
The Koala Bear, It was suffering because of the way that the CO2 increased in the atmosphere which affects Eucalyptus trees that they live
