Is Global Warming a True Crisis?

By Greg Tilley


We've been hearing the warnings of global warming problems for quite some time now. Green living is being promoted to help stop some of global warming effects and save the environment.

The question is whether those threats are just a hype to further political awareness or are they real? When we speak of global warming, we refer to the earth's temperature near the surface air. As it absorbs some of the heat from the sun, it allows the earth to be habitable.

Greenhouse gases that have been released into the earth's atmosphere are contributing to the rise in the surface air temperature. What is the impact this is having on the earth? According to scientists, the average temperature in the last century has risen. They think that the increase came in the last couple of decades. Scientists also believe that the rise will continue at a faster pace for the future since the increase is steadily rising.

Over time, arctic ice is slowly disappearing. The warmer temperatures caused by the global warming effects are melting the ice. Polar bears are feeling the effects of the melting ice as they find themselves stranded in the middle of the open sea. Ultimately, these polar bears are losing their life by drowning in the seas trying to find more ice patches to climb onto.

With the melting of the ice, we're seeing a rise in the sea levels. Because the temperatures are soaring at a rapid rate, the rise will become a problem in the future. The rising of the water level may cause flooding and it will be difficult to pump it out of the areas where people live. Precipitation is also increasing.

The amount of rainfall and snowfall is increasing over time. Storms are not only becoming more abundant, but we're starting to see them increase in intensity as well. There will probably be more hurricanes and they may be stronger and reach farther inland.

The warming temperatures also causes more evaporation to happen. The more evaporating we see, the more chances for these storms to develop, which could ultimately result in the high category hurricanes, we're seeing today. Driving people from their flooded homes are heavier rainfalls which would probably occur.

The ecosystems are seeing hardships, too. There are species of animals slowly dwindling in numbers and struggling to survive extinction while others move northward to look for livable conditions.

Even if only slow effects are being shown by global warming, unless we start to reverse it, they will increase over time. By using some green living methods in our daily lives, we can slow down those disastrous effects to save the planet for our heirs.
