The temperature all around the world is increasing. This is a fact and there is no evidence that says otherwise. According to nasa.gov (2014), “the average global temperature on Earth has increased by about 0.8o Celsius (1.4o Fahrenheit) since 1880.” This means that since around the beginning of the industrial revolution, the Earth’s temperature has steadily increased by a number that seems relatively small, but is it? While the number may seem small, it takes a massive amount of energy (heat) to increase temperature on the global scale by that much. The world is a big place, it has many areas that are getting colder, but that means an even greater number of areas are getting just that much warmer. This also means region to region temperatures may be increasing more or less than the total average. For example, in California, not only do we have a drought, but undoubtable anyone who has lived here for a long time has noticed a big increase in temperature from what it used to be even back in the 1970’s.
This graph shows the upward trend since the 1880’s in our temperature. While many may dismiss this as an environmental shift or natural occurrence, almost all evidence points to the fact that we humans are having a direct impact on this warming, and are increasing its rate. This also applies to all companies who are doing such actions as pollution. At the moment, businesses are still doing more harm than good to our planet, and are not contributing as much as they need to be to fixing this trending temperature change.
The global average temperature is increasing and this will result in some impacts on the hydrological cycle, in addition to precipitation. In my research I have been able to gather some facts that shows the participation changes are different from region-to-region. Some areas are becoming wetter and others becoming dryer. In general most of the models have shown in high altitudes regions the precipitation will increase and it will decrease in most subtropical areas. Any changes in amount precipitation in regions will result in changes in rainfalls and water runoff. Shortage in them can cause serious concerns for resource managers and many communities. Beside precipitation in liquid form, the snow, sleet, hail and even mist can be a scope to measure the wetness of a region. The soil wetness helps drive farming and agriculture in areas. Many communities rely on the reservoirs which they originally formed around. The world map below shows the trend in which we see the precipitation change in different regions and predicted % of decrease or increase in different regions of world.
Along with global temperature increase, more water will evaporate into the atmosphere. The water vapor is categorized under Greenhouse gases. These gases will trap more of the heat from earth and keep them within the atmosphere. This will be a cycling effect for temperatures to increase. Meteorologists will call this a positive feedback.
Ocean Acidification is a phenomenon that will cause many problems in the atmosphere and the ocean’s ecosystem. As students that use technology throughout our daily lives contribute to the ocean’s acidification. Why? Our cellphones, computers, or laptops have a manufacturing process that outputs more C02 than a standard vehicle. The daily use of our electronic products require energy, which also influences fossil fuel burning. With globalization of technology, this whole process outputs massive amounts C02 that our ocean absorbs through the Ocean Atmosphere Exchange, which causes Ocean Acidification. Oceans can regulate their PH levels, but takes up to hundreds of years to reach equilibrium.
Another factoring problem that contributes to Ocean Acidification and climate change is the electronic waste (E-Waste). According to EPA studies, only a small percentage of E-Waste is recycled thus being heavily incinerated or placed in landfills. Electronic Waste contains toxic chemicals that can seep into the ocean when it is incinerated. Once the toxic chemicals reach the ocean, it can lengthen the equilibrium of ocean’s acidity due to another chemical needing to be buffered out. Algae and other sea plants can be killed off by the Ocean’s Acidity and by the toxic chemicals from E-Waste, consequently causing climate change since the ocean and photosynthesis will have a lesser effect on taking in C02.
The dangers of Ocean Acidification is dangerous to anyone. This can also be scary for students who love to go to beaches or fishers. Spending a Spring Break only to be crashed by a giant dead whale would be awful. More importantly, fishing and eating a fish that is ill from the ocean’s acidity or containing toxic chemicals can cause a widespread illness.
