How climate is changing as we know it

Temperature

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.

Cody's graph

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.

 

Species

Effects of Electronic waste on climate and species are noticeable also. It is the process of discarding used electronics for reuse, recycling, or salvage. Electronic waste can range from cell phones to TV’s to computer parts. These electronic waste parts contain many toxic chemicals that can change different species of the environment. These toxic chemicals are known as lead, antimony, mercury, cadmium and nickel.

Lead, a toxic chemical to humans and other species of animals, is contained in most old electronic devices. Lead can move in and out of environmental ecosystems and can go into animal’s bloodstream. Ocean disposal of electronic waste can spread lead into the ocean and kill different aquatic organisms. If in the bloodstream, it can harm central nervous system and the ability to create red blood cells. The poison can eventually reach to the heart and kidneys, which may mean death to many animals. Different species of duck, birds, black swans, and geese have been reported with lead poisoning and will be reduced in population. Aquatic animals can receive lead poisoning through the transfer of lead in water and sediments, which can kill them.

 

Precipitation

 

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.

Climatically Suitable Areas for Growing

 

Computers In the 21st century are becoming essential part of our daily life. From home, at work, or on the go, computers are quickly and constantly evolving. Computers have many benefit effects on lives, however, the production of these electronics also place a large strain on the environment.

 

Fac

 

The the manufacturing facilities of the production of computers are creating pollution in the environment due to computers requires a large amount of fossil fuels and chemicals. Although the fact that computers are continuing to decrease in size, computers still require 10 times their weight in chemicals and pollutants during manufacturing. The expel of these harmful chemical and pollution into the air created by computer production is harmful to the health of plant and animal species within close proximity which can cause destruction of endangered and limited habitats. The site of these facilities can cause habitat loss due to raw material demand or development on it. This would then cause disruption of habitat like the construction of pipelines that hinder the migration of animals. Wastes from producing of computers in these facilities also contribute to direct toxic effect on flora and fauna (e.g. pesticides) or that alter the functionality of an ecosystem in the surrounding environment. This is due to computers containing heavy metals like lead and other toxic chemicals that can pollute the soil and contaminate groundwater when they are dumped into landfills. Thus, production of computers causes contamination and destruction of climatically suitable areas for growing.
Ocean Acidification

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.
