Global issue of sustainability-Climate change
Climate change especially global warming is one of the environmental disasters are now posting severe threats to both planetary sustainability and human-being. Some researchers argue its Earth’s natural climate fluctuation despite of human activities on environment, whereas more and more researchers have shown the evidence of this imbalance energy result from anthropogenic activities not only in regards to the warmth of the atmosphere but also lead to the melt of the ice cap and the rise of the oceans temperature (Trenberth ; Fasullo, 2013). In the context of the impact on human health and sustainability, this essay will describe the historical and current state of climate change following the relationships among greenhouse gas production, industrialization, economic expansion and population growth will be discussed. Consideration of the worldwide implications in regards to climate change for planetary and human health will be discussed.
For many decades, scientists have monitored the Earth’s temperature has naturally altered within the solar system for millions of years (Climate Change in Australia, 2016). However, human activity since the Industrial Revolution has pushed the consequence of this inherent balance to an immense degree, on one hand, global warming is one of the major issues impact our livelihood and environment in the 21st century (Fang, Zhu, Wang, Yue & Shen, 2011). On the other hand, the number and the strength of extreme weather events, such as heat waves, severe storms, cyclones, droughts and floods are significantly increased. The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR 5) concludes the global mean temperature since 1951 has increased at a rate of 0.12 ? per decade and from 1880 to 2012, it has climbed by 0.85? (IPCC, 2013). In addition, from 1979 to 2012, the amount of Arctic sea ice has diminished with a rate of 3.5% per decade; the worldwide average sea level has gradually risen at a rate of 1.8mm per year from 1961 to 2003 accordingly (Climate Change in Australia, 2016). Meanwhile, the majority of the excessive energy reserved in the climate system which causes the warmth of the upper ocean layer (Climate Change In Australia, 2016). Consequently, the increase of global temperature will have the severe impact on environmental systems; such effects will, in turn, worsen the circumstances of all the species and human-being living in the ecosystems (Fang, Zhu, Wang, Yue & Shen, 2011).
