Understanding Global Warming
What is global warming? Why is it such a big deal? It is perfectly fine to ask such a question because the media is constantly expressing all of the messages of global disaster and spreading panic without ever taking the time to calmly explain what, exactly global warming is. Basically, it is the increase in average temperature of the Earth’s “near surface air” and the oceans. This is a human induced event that has been occurring since the middle of the last century.
Global warming will cause the sea levels to rise because of increased temperatures at the polar ice caps as well. This will increase precipitation and also change its predictable patterns. This means an expansion of what is known as “subtropical desert regions” and Arctic shrinkage which will bring about a release of methane gases that will shrink the overall size of the exiting rainforests. The continuing effects of global warming will also include more extreme weather events such as hurricanes, tornadoes and typhoons and all of this will eventually impact agricultural yields. Unfortunately, the change in the seas will change trade routes, cause extinctions due to habitat loss and spread disease into areas where it had not previously existed.
It is easy to see why news forecasters speak so intensely about global warming, but there are things that can be done to slow the process, and even correct it. Consumers can begin to consider their “carbon footprint” and greenhouse gas emissions. They can consider the immediate effects of such actions as using an air conditioner or hairdryer, playing video games or microwaving a meal and they can consider planting trees, recycling and purchasing green brands of products that are made with as little energy and materials as possible.
There are many ways to combat global warming and it really is a matter of life or death. Many beloved species are all ready facing imminent danger. Consider the glorious polar bear whose habitat is disappearing and whose food sources are also fading. In less than fifty years of active observation, scientists are seeing that their demise in the wild is a significant possibility in the coming decades. Currently there are also ice shelves in both polar regions that are threatening collapse, in fact some pieces the size of the state of Connecticut have all ready given way. These are all serious issues that need immediate measures to be taken. It is not only government agencies and corporations that must work to change the course of events, but it is each and every person on the planet who most help to save it.
