Further hazardous effect of global warming is not just an issue. We do have had some early signs of the global warming, while the coming effects are even inconceivably scaring. Just imagine, an increase of one degree Celsius in global mean temperature will cause the melting of the Greenland Icecap which holds enough water to raise global sea level by 20 feet.
Scientists are still debating whether global warming is caused by the human activities or just another natural occurrence. One thing sure is the earth’s temperature keeps increasing in unprecedented speed, and if we believe this is natural occurrence, then there is nothing we should do, but just wait for the worst to come. To some people who believe it is caused by our activities, then we still have hope because we still can avoid further hazardous effects of global warming by practicing a way of living that minimizing the greenhouse gases.
Now, no matter how different the opinions are on the sources of global warming, we all agree that we are approaching to its fearsome impacts. These are among what will happen if the temperature keeps increasing:
The fresh water on Earth is only 3% of the total water. 97% are salt water in the ocean. 68.7% of this fresh water is stored as cap ice and glaciers, but the increasing temperature will melt them, meaning pouring out our limited water. Simulations project that nearly all of the world’s glaciers would melt at a 4°C temperature rise. With prediction of average global temperature to rise between 1.4 and 5.8°C by the end of the 21st century, there will be loss of significant fresh water on earth.
Today, water is already a dangerously rare commodity in Africa and Asia and according to the Intergovernmental Panel on Climate Change (IPCC), global warming will exacerbate the conditions and could lead to conflicts and war.
Shortage of fresh water.
Even in some countries prolonged period of growing season which means to more agriculture production, some other countries will suffer from disadvantageous impacts on this global warming, such as severe drought and floods caused by sea level rising. Those epic floods and intense drought will both have impact on the agriculture yields. IPCC has predicted by 2020 less rainfall due to climate change could reduce agriculture yields by up to 50 percent in Arfrica that leads to unedequate supply of water and food to approximately 75 million to 250 million people. Food shortages will as well occur to 130 million people in Asia. The percentage of the globe enduring severe drought could increase 30-fold by the end of the century, which may lead to sterner famine.
Higher risk on human health.
Human health will be at higher risk level as higher temperature may enable disease-carrying rodents and bugs, such as mosquitoes and ticks, to spread to other regions of the world where it is currently too cold for their habitats. The incidence of insect-borne illnesses like dengue fever, encephalitis, malaria, and other afflictions will significantly increase. By 2085 the risk of dengue fever is estimated to increase to 3.5 billion people due to climate change. (IPCC).
Increasing temperatures will make hotter summers that encourage heat-related illnesses, while breathing problem is notably inflate as air pollution in cities increased. Hot temperatures increase the ozone concentration, which can damage people’s lung tissue. Hotter temperature will force the human cardiovascular system in order to cool their body, causing those who have heart problems become more vulnerable.
Famine and fresh water shortage will become another threat for human health. IPPC also predicts that by 2050 diarrhea-related diseases will likely increase by up to 5 percent in poor countries.
Global Warming Effects on flora and fauna.
A global warming effect on the animal is even more severe. According to IPCC 20-30% of today’s species could be extinct by 2100 if global temperatures exceed 2 -3 degrees of pre-industrial levels.
Another study said that bird extinction rates could be as high as 38 percent in Europe, and 72 percent in northeastern Australia, if global warming exceeds 2 º C above pre-industrial levels (currently it is 0.8ºC above).
The global warming effects on flora are also threatening. A research made by some US biologist found that some 50% of the Earth’s plant species are heading to extinction. Those species live only in small geographical ranges with specific habitats will be under most risk.
Those terrible effects of global warming are indeed too costly to bear. If you – like I do - believe there are still lots of things we can do to fight this, then perhaps you might be interested to summon up some major tips to do it.
