For the past 650 million years the atmospheric CO2 levels have never been more than 300 parts per million (ppm). However between the years of 1950 and 2012, we have somehow managed to rise above what seemed to be an unattainable level of CO2 levels and are now sitting at approximately 380 ppm!. Because of this, the warming trend of the earth is continuing at a rate that was unprecedented in the past 1,300 years.
Some specific examples of evidence that points towards climate change is the rising sea levels. Globally sea levels have risen approximately 17 centimetres just in the last 100 years. There is no surprise that the rate in the last decade is close to double that of the previous century. Small island nations are the most vulnerable to this specific example of climate change.
Tuvalu for example has had extreme experiences with rising sea levels. Waves have been washing over main roads, coconut trees are halfway under water and areas of cropland have been deemed unusable due to saltwater overtaking the land. Over the next 50 years if something isn’t done the Tuvalu’s entire population of 11, 800 people will have to be evacuated. This country is in danger of being completely swallowed due to climate change.
Since 1880, the temperature of the earth has continued to rise. The 1970s is home to most of the quick rises in temperature. However, 10 of the warmest recorded years in history are all within the last 12 years.
The land of the earth is not the only part that has been suffering though rising temperatures. The oceans have also collected a large amount of this increased heat. The temperature of the water does not just affect the actual temperature of the water; it also affects all ecosystems that lie under the sea. Some of these ecosystems can be extremely sensitive to the temperatures of the surrounding water. Coral is an example that is most vulnerable to changing sea temperatures.
Glaciers around the world are simply retreating due to the quickly rising temperatures globally. Mount Kilimanjaro located in Tanzania, Africa has seen a drastic glacier retreat. In just seven years the glaciers that once sat upon the volcano.
In 1997 the top of the volcano was covered with snow and ice. Only seven years later in the year 2000 the volcano is no longer covered. Ice and snow is sparse over the top in small areas. Other regions also experiencing the same negative effect of climate change include, the Alps, Himalayas, Rockies, and Alaska.
Anyway, as we all know climate change is something that is affecting us all, whether we believe it or not. All these facts prove what is happening on a global scale. These are all things which we are contributing to in small ways. We see how climate change has affected us in little ways and then again in ways that are more significant.
John Kasich is the governor of Ohio. About a week ago at a GOP fundraiser he explained that climate change is a problem. He stated, “This isn’t always popular to always say, but I believe there is a problem with climates, climate change in the atmosphere.” Mitt Romney is the governor of Massachusetts. His position on climate change is that it’s real and, “human activity contributes to it”. However he doesn’t know to what extent.
In my opinion there are way too many facts and events happening for people to say that climate change isn’t happening. For some people to just be realizing it now is heartbreaking.
