What are the potential effects of global warming in terms of climate change and how can they be arrested?
Global warming has been a big issue among the scientist up to the extent that it is said that global warming is caused by both human and he environment. Professor Bob Carter of James Cook University, Queensland in his interview in Nzone Tonight said that every scientist does believe that humans have an effect on climate change. However, he also mentions that some places are warming and some places are cooling. Over the last century, our planet Earth has been increasing its temperature without bound. The average surface temperature of the Earth rose 0.6 to 0.9 degrees Celsius (1.08°F to 1.62°F) between 1906 and 2006, and the rate of temperature increase nearly doubled in the last 50 years.(Holli Riebeek, 2007) This is one of the evidence showing global warming is occurring at a rising rate.
As we slowly let global warming becomes uncontrolled, some studies show the potential occurrences to our beloved Earth. One inevitable consequence of global warming is sea-level rise. The problem is serious because as much as 10 percent of the world’s population lives in coastal areas less than 10 meters (about 30 feet) above sea level. (Holli Riebeek, 2007) If this is probably to happen, as sea levels rise, these communities will become increasingly vulnerable to storm damage and flooding. Among the most vulnerable countries is Bangladesh, which has low elevation, a high population density, and is one of the world’s poorest nations. And it will be a hard blow to them as they do not have resources to fend off changes in climate. Water expands as it warms so, as the oceans are heated, the water they contain takes up more volume, and this makes the level of the seas rise. The seas also rise when glaciers and ice sheets melt, feeding more water into the oceans. (Chris Woodford, 2006) According to Al Gore in “An Inconvenient Truth”, he said that the maps of the world also would have to be redrawn as a result of the sea level rise.
Global warming paradoxically causes not only more flooding but also more droughts. (Al Gore, 2007) One of the reasons is that global warming not only increases precipitation worldwide but it also relocates the precipitation. This is to show that the Earth’s temperature is predicted to rise even higher in the future. Global warming will result in more hot days and fewer cool days, with the greatest warming happening over land. Longer, more intense heat waves will become more frequent. (Holli Riebeek, 2007) The warming will enhance coastal erosion, extend the growing season, and melt the ice caps and glaciers. As for now, even mosquitoes are able to climb higher altitudes, not only mosquitoes, but even vectors of infectious diseases spreading. And there has been appearance of new diseases in the last quarter century like SARS, who knows there could be more in the near future. Consequently, species those are not able to adapt the sudden climate change are likely to face extinction. The ultimate consequence of this is hurricanes will likely increase in intensity due to warmer ocean surface temperatures.
As Al Gore said that we are the cause of global warming, we can also contribute to help in reducing the factors of global warming. To reduce the impact of climate change, we need to reduce global warming. (Chris Woodford, 2006) In another meaning, it can be done by producing fewer carbon dioxide emissions and it might mean using less energy or using it more efficiently. To reduce carbon dioxide emission, we should use electric-efficiency appliances by replacing incandescent lamps in our homes with energy-saving fluorescent lamps. We should also consider in buying a hybrid car or a higher mileage cars to help in reducing carbon emission. Use bicycle or walk when you can, rather than driving your car. Other than that, we should plant more trees, recycle useable items. Lastly, we should also join international efforts to stop global warming.
On and all, global warming is causing havoc to human and the environment. We can consider the “climate change skeptics” that they say it is an environmental phenomenon. Nonetheless, we also play a big role in handling this contentious issue. We are to be blamed for our mistakes when the whole world is facing the consequence in the future that is if we do not take immediate actions from now. Prevent is better than cure. Therefore, we have to thrive in the responsibility to make the Earth a better place to live for the sake of our children that will too, live in this world.
