In recent years, Global Warming and Climate change frequently appear in our lives. There are many different reasons caused the global warming include natural causes and human influence. But human do not care the earth, so human cause global warming is more than natural causes global warming. Global warming refers only to the Earth’s rising surface temperature, while climate change is a change in global or regional climate patterns and attributed the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. It can be seeming a relation that influence each other.
Industrial revolution has left a big behind for global warming. We always like using fossil fuels for power machines because it can use less labor and more efficient. For the industrialization we are produce pretty much carbon emissions then released into the atmosphere. As carbon released into the atmosphere and mixture with air then created CO2 gas also this gas is a key player caused global warming. Imagine if Australia increased 1 to 2 degree temperature it will around 30 to 50 species of native flora and fauna can possibly become extinct. What about other country will be facing?
There is also a common misunderstand that global warming only effect less cold and the weather in summer will be hotter, once the temperatures over people’s normal body temperature, it will become very difficult for the body to cool down. It will be a challenge for the patient people and olders. Then it means will cause the increases in the use of air conditioning, which requires more energy to use this will created more additional pollute gases like CO2. In 2015 the hottest year, there are many countries faced extreme heat wave and India was suffering the second most deadly heat wave.
Australia is also a country vulnerable to the effects of global warming projected. Due to the degree increased, the Great Barrier Reef has experienced two major bleaching in 1998 and 2002, respectively 42% and 54% of reefs were affected by bleaching. When the ocean absorbs the carbon dioxide from the air and lead to ocean acidification, it will be a transfer between ocean and air which cause large scale winds resulting in extreme weather, it will straightly damage human housing. The fees for rebuilding will hurt the Australian hip pocket and leave people become homeless.
If this isn’t bad enough to make you attention, let’s see this picture, ( polar bear) The study shows polar bears really are starving because of global warming, Because of melting sea ice, there will more polar bears will starve. The main food for polar bear are seals, they usually waiting for several house in seals’ cone shaped breathing holes in the sea ice. When a seal surfaces to breathe, the bear stands on its had legs and smacks it on the head with bot of its front paws to stun it. Then pick the seals onto the ice. So this is why the melting of the Arctic sea ice threatens polar survival. In addition, the climate in Arctic was faster than anywhere increased heating, and sea ice is shrinking 14 percent per decade.
Even today, in the middle of the bitter cold Arctic winter, satellites show there is about 770,000 square miles less sea ice than the 1981 to 2010 median. As the sea ice melts earlier and earlier, polar bears are forced to swim more and more, to reach seal population, one female bear Griffen studies swam 426 miles over nine days, she lost 22 percent of her body weight, and lose the nursing cub that had started the journey with her. Think about as a mother, when you on the way to finding some food to eat, you were lost you child, what a painful thing this is. There are something already being seen in western Hudson Bay and around the southern Beaufort Sea, more swimming could lead to smaller bears, reduced reproduction rates, and even increased risk of death.
There is no doubt that as the sea ice declines more and more bears are going to starve to death, and polar bears are considered endangered in the U. S and are listed as vulnerable， because their sea ice habitat is under threat from climate change.
