Whenpeople think about their future, they usually only consider things that willaffect or benefit their personal lives. This may include the city that theywill live in, the job they may have five years down the road, or the place theymight retire. This is usually because people do not think the environment hasan impact on their life. Few people realize and process the dire changes thatare going on in their surroundings.

Global warming, also known as thegreenhouse effect, is a rise in the entire temperature of the earth’satmosphere. The topic has been receiving a lot of attention from scientists inrecent years because of a sudden exponential increase in the earth’stemperature. Climate change is something that has been put off for many years,however many people will soon find that it is affecting the earth drasticallyevery day. Global warming is proven to be real because of the rise inEarth’s average temperature, the rise in ocean temperature and levels, andocean acidification.             Throughout its long history, Earth’stemperature has increased and decreased because of the subtle shifts of Earth’sorbit and atmospheric changes. However, in the past century, scientists havenoticed an unnatural rise in the Earth’s temperature and have found the cause: humanity.The global average of the Earth has risen significantly in the last fewdecades, and temperatures are certain to go up further. According to Global Warming, “Theglobal average surface temperature rose 0.

6 to 0.9 degrees Celsius (1.1 to 1.

6°F) between 1906 and 2005, and the rate oftemperature increase has nearly doubled in the last 50 years.” There are many effects of global warming, but one ofthe most important effects of global warming is the disastrous speed at whichthe glaciers and polar ice caps are melting. Anothereffect is the species loss of habitat. Species that include polar bears andtropical frogs will be extinct due to climate change.

In addition, variousbirds will migrate to other places because they cannot adapt to the rapid changein temperature. GlobalWarming also explains that over the past 250 years, humans have beenartificially raising the concentration of greenhouse gases in the atmosphere atan ever-increasing rate by burning fossil fuels and from cutting downcarbon-absorbing forests. The article continues to explain that carbon dioxide levels have increased nearly 38% since the IndustrialRevolution (1750s) as of 2009 and methane levels have increased 148%. Asdisplayed, researchers have discovered that humans have, in fact, been thecause of the recent increase in greenhouse gases. These gases are mainlyproduced by fossil fuels released from electrical production, transportationindustries, and agriculture. Although the amount of released emissions can riseand fall due to changes in the economy, the fossil fuels penetrating ouratmosphere is too much for it to handle. So, how can people assist the movementto decrease greenhouse gas emissions? Some ways one can help is by drivingless, carpooling, reusing, reducing and recycling, reducing waste, and by buyingenergy-efficient appliances.            Withthe rapid growth of knowledge in climate change, especially in sea level rise,its science and impacts, it is hardly surprising that the relationship betweensea level rise and its impact on our environment has attracted considerableattention in recent years.

 When water heats up, it expands, causinga rapid rise in sea level. Sea level rise causes the flooding of coastalhabitats for humans, as well as plants and animals, shoreline erosion, and morepowerful storm surges that can devastate low-lying areas. Warmer seatemperatures are also associated with the spread of invasive species and marinediseases, leading to the overall extinction of several species. NOAA explains,”Global sea level has been rising over the past century, and the rate hasincreased in recent decades. In 2014, the global sea level was 2.6inches above the 1993 average—the highestannual average in the satellite record (1993-present).

Sea level continues torise at a rate of about one-eighth of an inch per year.” As shown, sea levels have beenincreasing significantly recently, which may pose disasters in the Earth’secosystems. Rising sea level has worldwide consequences because of itspotential to alter ecosystems and the vulnerability of coastal regions all overthe globe. At local scales, sea-level rise is likely to increase sedimentaryprocesses that can interfere with feeding, recruitment, photosynthesis, andother key physiological reef processes.

This comes to show how sea level risecan wipe out whole ecosystems of coral reefs. Projections of Sea-Level Rise explains that sea level rise can cause increased sedimentation due to shorelineerosion which could smother reefs or reduce sunlight needed for photosynthesis.Even small increases in sea level can increase turbidity on fringing reefsthrough increasing re-suspension of fine sediment on reef flats (the innerportion of fringing reefs closer to sediment sources) and by increasing coastalerosion and transport of fine sediment to adjacent reefs. It finally goes on tosay that the smothering of reef structures led to a rapid retreat of reefsduring the rapid and large (6 meter) sea-level rise of the last interglacial. Ifocean and atmospheric warming continues, sea levels are estimated to rise inthe next centuries.  The common response to sea level rise is tounderstand the impacts of it and to relate them to problems that affecteveryone. When sea levels rise rapidly, asthey have been doing, even a small increase can have devastating effects oncoastal habitats. As seawater reaches farther inland, it can cause destructiveerosion, wetland flooding, aquifer and agricultural soil contamination, andlost habitat for fish, birds, and plants.

            Since the industrialrevolution, the concentration of carbon dioxide (CO2) in theatmosphere has increased due to the burning of fossilfuels and land use change. Determiningwhen global warming began and how quickly the Earth has warmed since then isessential for understanding how much we have altered the climate in differentparts of the world. Climate changes affect many ecosystems in the world, butthe effect of human activity on the world’s oceans has received littleattention. The truth is, earth’s oceans are suffering severe, irreversibleeffects from human activity.

The most prominent phenomena affecting oceanstoday is increased acidification, which worsens day-to-day and is likely tocause permanent damage. The OceanPortal Team describes, “Such a relativelyquick change in ocean chemistry doesn’t give marine life, which evolved overmillions of years in an ocean with a generally stable pH, much time to adapt.In fact, the shells of some animals are already dissolving in the more acidic seawater, and that’s just one way that acidification mayaffect ocean life.” As explained, ocean acidification is expected to havedramatic and negative impacts on ocean ecosystems. The recent increase iscausing plants, animals, and essential bacteria to become vulnerable anddissolve.

Just one mistake in the bionetwork could devastate the entire foodchain. In addition, beyond lost biodiversity,acidification will affect fisheries and aquaculture, threatening food securityfor millions of people, as well as tourism and other sea-related economies. The Ocean Portal Team also explains howeven though the ocean is immense, enough carbon dioxide can have a majorimpact. Finally, the article explains that in the past 200 years alone, oceanwater has become 30 percent more acidic—faster than any known change in oceanchemistry in the last 50 million years. Greater acidity causes animals to havetrouble distinguishing the smell of their species and that of their predators.

This causes increased predation, leading to the food web being at risk.Overall, ocean acidification is another example of global warming’s negativeeffects on the Earth and its ecosystems.              On the other hand, some people may say that globalwarming is a natural occurrence that normally occurs within the Earth’satmosphere.

Although Earth’s climate has changed naturally over the past hundredsof thousands of years, temperature-warming trends over the past century areextremely likely due to human activities. In addition, most of the leading scientific organizations worldwide have issued publicstatements endorsing this position. According to Scientific consensus, the following scientific associations havebacked up the unnatural increase of global warming: AmericanAssociation for the Advancement of Science, American Chemical Society, AmericanGeophysical Union,American Medical Association, AmericanMeteorological Society, American Physical Society, and The Geological Societyof America. In conclusion, global warming has in fact had a recent increasebecause of human activity.            Inthe end, global warming is a serious problem that is currently effecting human,plant and animal lives, ecosystems, and the atmosphere.

If this generationdoesn’t start to take care of the Earth and greenhouse gas emission release,the planet will be in danger. People can help resolve the problem by driving less, carpooling, reusing, reducing and recycling, reducingwaste, and by buying energy-efficient appliances. Global warming is proven to be real because of the rise inEarth’s average temperature, the rise in ocean temperature and levels, andocean acidification.
