One of the biggest problems facing mankind is global warming. More than 97 perecent of the world scientists believed that human activities mainly the burning of fossil fuel caused global warming. Exacerbated by global warming, the occurrence of extreme weather events such as hurricanes, droughts, rising sea level, floods,and heatwaves are becoming more frequent and sever. In the past two decades global warming induced extreme weather affected almost half of the world population. The scientific evidence is now clear that global warming is a growing threat to society. Hoping to reach a significant agreement to reduce greenhouse gas emissions and contained the average rise in global temperature under 2C, leaders around the world have…show more content…
In 2009 former NASA climate scientist James Hansen set a CO2 level of 350 part per million (ppm) as a threshold for Earth’s safety (Jill, p. 963). As such, according to James any level above the threshold will lead to dangerous warming (Jill, p.963). However,carbon dioxide measurement taken at an observatory in Mauna Loa, Hawaii show that global carbon dioxide concentration have climbed to 400 ppm (Weeks, p. 524). Jill U. Adams, conclude that, according to current projection, the planet 's temperature will rise to at least 2 degrees by the end of the century and an increase topping that could lead to a host of environmental crises, including flooding from rising sea level and catastrophic weather events (Jill, p.964).
Extreme weather conditions like drought, heat waves, flood, hurricane, and violent storm have been part of nature since the beginning of time. But with global warming, according to Tigay Channen, nowadays extreme weather events like hurricanes, drought, flooding as a result of rising sea level as well as heatwaves are becoming more frequent and more extreme (p.737). A number of extreme weather events have occurred in 2015. California has been affected by the devastating drought this year and so is Australia and Africa. Mexico has seen the strongest hurricane, hurricane patricia last month. Deadly heat waves associated with global warming have been blamed for thousands of deaths in India, Pakistan, and Egypt (Freedman).
