Global warming

Global warming

Global warming has been occurring for millions of years with natural temperature fluctuations; however the past half century has resulted In exponential growth In temperatures worldwide. “The hottest years on record have all occurred since 1990, and by the end of the 12th century the average U. S. Temperatures could be up to 9 degrees higher”. Among other global Issues rolling ocean temperatures are great for your summer vacation on the beach; however the temperatures are causing algae and coral reefs to die effecting food chains.

The resulting ripples in the food chain are catastrophic to food sources and economical system humans use for their lively hood. Weather patterns are changing causing more droughts and floods, and hurricanes and tropical storms are stronger than ever because of the warmer oceans causing more destruction. Global warming is a natural phenomenon caused over millions of years, except global warming is now occurring faster than ever recorded. The increasing greenhouse emissions caused by the human race will continue to pollute the earth far too rapidly, and will have extreme long lasting consequences.

According to the ; “The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (EPIC) states: It Is a greater than a 90 percent certainty that emissions of heat-trapping gases from human satellites have caused Increased global average temperatures since the mid-20th century”. The united States is the largest source of carbon dioxide pollution in the world producing 2. 5 billion tons every year (2005). CO isn’t the only greenhouse gas responsible for heating up the planet by trapping the heat.

Other gases include methane which traps more than 20 times the heat than CO, and nitrous oxide at 300 times more heat, and hilariousness’s has the heat-trapping potential thousands of more times greater than CO. Naturally the world’s oceans and plants absorb CO to keep the levels under control. The excessive amounts of carbon dioxide Introduced in the atmosphere are too great and the natural process can’t keep up. The downside to the natural absorption of CO Into the oceans cause the ocean to become acidic, which limits the ability of future absorption and more CO Is left In the atmosphere.

Trees and plants also require carbon dioxide in order to survive, also reducing the levels of CO; however when trees are cut down or used as firewood they release more CO causing more damage to the atmosphere. What are warmer temperatures doing to climates worldwide? For example in 2003 ” extreme heat waves caused more than 20,000 deaths in Europe and more than 1,500 deaths in India” Extreme heat waves cause massive or even catastrophic stress on power grids; because of the potential millions of AC units running to keep the population safe from the heat.

The resulting blackouts leave thousands to millions without power struggling with the extreme heat causing exhaustion, heat strokes, ND can affect existing medical conditions. “In 2002 droughts created severe dust storms In Montana, Colorado and Kansas. The same year floods in Texas, Montana and North Dakota caused millions of dollars In damage. ” Changing weather patterns will continue to affect all areas of the global leaving many different types of disastrous to all coastal areas with rising sea levels up to 23 inches.

For example Venice, Italy is a beautiful city built on 118 different small islands which are linked by bridges and canals. Rising water will put the whole city in danger of flooding and will splice over 270,000 people. This is one of many coastal locations that will be affected with rising water. Except that’s not the only problem hurricanes and tropical storms are Just as disastrous because of the warming ocean water feeding stronger storms. Hurricanes and tropical storms are fueled by warm oceans; which are causing the strongest storms ever to occur. (Insert example from sources about hurricanes and tropical storms. What medical concerns arise from the worlds changing climates? Heat waves will increase serious health risks, which can lead to exhaustion, heat strokes, and even affect existing medical conditions. Flooding and higher precipitation will lead to higher insect populations helping spread many forms diseases across the global. Severe droughts in regions will disruption food supplies causing increased prices for food and shortages leading to wars over food causing chaos. Animal such as cattle can’t survive floods and heat waves creating a shortage of meat as well.

Season changes will affect allergies; however earlier spring causes floods from increased snow melting, and higher chance of wildfires when egging dry out earlier than expected. Global economies would be severely impacted (To be added upon, need more research/time) Many species rely on certain temperatures of ocean water in order to survive; in order for the species to live they must move north to a colder region in order to survive the rapid change in climate. Rapid climate changes do not allow enough time for species to adapt to the new environment and they die off and become extinct.

The extinction of species cause massive ripples in food chains; which can affect all living things. For example if the algae and coral reefs died out that would affect small fish’s food and habitat causing them to die as well. The small fish are eaten by larger predators; which are prey to even larger predators. If you kill off the bottom source of the food chain the CEO system it will collapse because of the lack of food. The same affect happens when you have too many of one species. For example many people are afraid of sharks and wouldn’t mind them going extinct, because it makes the ocean safer for us.

If the sharks disappear there is nothing to control the fish population of what the sharks ensure; which causes those species to flourish and consume more fish as food further depleting food sources that cannot sustain higher numbers of predators. In conclusion global warming has been made worse in the last 100 years than ever recorded in human history going back hundreds of thousands of years when our ancestors migrated out of Africa 800,000 years ago. Every part of the global will be affected, but not all will affected the same way. Some regions will have increased flooding and precipitation, while others have droughts and wild fires.
