However, it has also been found that there is a possibility of cyclones actually mitigating coral bleaching (Baker et al., 2008; Schultz, 2012). With even just a 2°C increase in temperature the probability of COTS survival escalates by 240 per cent under certain conditions (Australian Institute of Marine Science, 2015). However, repeated bleaching events result in higher mortality rates. The Caribbean has been experiences continuous declines of reef sites due to repeated bleaching events (Baker et al., 2008). There is no doubt that oceans surrounding Australia have drastically warmed since 1910 (Bureau of Meteorology, 2014), and this warming affects the
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future. Of all the effects of global warming, the extreme weather that is taking place all over the world is the most obvious one.
Global warming is a war that we should not get involved with because we will lose if changes aren’t made soon. Global warming is the rapid increase in earth’s average surface temperature over the past century due to the fact that greenhouse gases are being released into the atmosphere increasing the earth’s average temperature (EarthObservatory.NASA.org). There are many contributing factors that play a role into the cause of global warming. Greenhouse gasses are gasses such as Carbon Dioxide, Methane, Nitrous Oxide, and F-gasses that trap heat in the atmosphere. The heat that is trapped in the earth’s atmosphere is a slowly melting glaciers, cause sea levels to rise and is messing with the weather patterns.
Unfortunately, heat and weather is not the only thing happening with global warming. Rising sea levels is also a major concern that has an eye out for. As this will start happening, the sea levels will start to erode coasts and cause more frequent flooding. It may almost come to the conclusion where some islands will disappear. This could start to become a major concern because ten percent of land on the world lives approximately ten meters above sea level.
Possibly, the hurricanes and tsunamis will become potentially stronger than they were ever before. Heat waves that will appear as a result of global warming will assist in the melting of ice. Ice, especially around the poles of the Earth, will melt and pose a danger to the wildlife. Greenhouse gases also pose a threat to the environment of our world. The average temperature of the Earth will fluctuate, and it will become difficult for weathermen to predict the weather for the following days.
5- Rise in the sea level: Rise in the sea level is a globally expected phenomenon. Levels of oceans and seas are globally monitored through satellites. Since 1870 to 2013, total rise in the sea level is approximately 18 centimetres. Meanwhile, coastal areas in Arab countries are threatened by the rise in the sea level, this includes Alexandria in Egypt. Studies have expected rise in the sea level by 0.5 to one metre in the next century, this rise is expected to flood 30% of the city, which will definitely cause damages to humans, buildings, and the agricultural land through salinization .
Global warming has been one of the most challenging problems our society has encountered and people don't acknowledge that our climate change is becoming worse as the time goes by. Climate change which is said to be the regular or ordinary weather in an environment consists of patterns like seasons and temperature. Climate patterns play such an important role in constructing an essential ecosystem, human economies and cultures that rely on them has raised the surface of the world's oceans in recent decades by melting glaciers and causing seawater to expand as it warms. In addition, thermal expansion from current and future greenhouse gas desolation and increasing mass losses from the glaciers and ice sheets due to warming oceans and surface temperatures have affected the rising of sea levels. The deficit of mass from glaciers and also the ice sheets of Greenland and Antarctica play a role to sea level rises each year passes.
Storms are an inevitable part of living on the coast, but the need for long-term recovery and preparation for the future is growing due to the threat of climate change. Climate Change and Sea Level Rise While it is hard to directly connect Hurricane Sandy to global warming, it is clear that warmer waters and increased sea level contributed to the severity of the storm. Higher sea levels increase the chance that hurricane winds will bring more water on land and storm surges that reach further inland. The Atlantic region is already experiencing sea level rise, and globally this trend is expected to continue. Ocean temperatures are also on the rise, an... ... middle of paper ... ...ments.
Global Warming As the world's expanding population burns large quantities of fossil fuels and simultaneously cuts down large expanses of forests worldwide, the concentrations of CO2 and other greenhouse gases are building up in the atmosphere. "The green house effect is the (imperfect) analogy used to explain the atmospheric phenomenon that keeps our planet warm enough to sustain life." There is mounting evidence that this shift in Earth's atmosphere will lead to global changes and potentially major climatic disruptions. The major concern is not that the greenhouse effect is real;"we wouldn't be here if it wasn't." It is that it "may be exacerbated by anthropogenic increases in the effective gasses, threatening a disruption to the equilibrium between incoming and outgoing energy, and a resulting average global warming."
The second problem is extreme events. Climate change include floods, storms, heat-waves and intense precipitation, these effects will cause terrible harm to the economic development of the coastal cities. The total damage cost of Hurricane Katrina was $130 billion, accounted for 25 per cent with the event of full macro economic costs. Extremes events in the developing countries have an undeniable influence on the economic growth (Hallegatte, 2006 and Hallegatte et al, 2007, p.33). The third problem is energy use.
