Is gas effect since 1824, where Joseph

Is our plant doomed to burn?  Whatis global warming and what causes it? Simply put the national graphic explain globalwarming as the average global temperature increasing.The article states that this average temperature is caused by gases that trapheat form the sun.             “the greenhouse effect” is the warming that happenswhen certain gases in Earth’s atmosphere trap heat. These gases let in lightbut keep heat from escaping, like the glass walls of a greenhouse.” 6How these greenhouseeffect works are that the sunlight entersthe earth’s atmosphere where some of the lightenergy radiates as heat in the atmosphere. What the greenhouse gases do is thatthey trap the heat energy from escaping earth. From this national graphic source, I learnt that scientist knew about thisso-called greenhouse gas effect since1824, where Joseph Fourier had worked out that the earth should be a lot colderbut did not have the means or technology to know why the earth was hotter thanit should be.

Then Swedish chemist SavanteArrhenius discovered that us humans could affect the greenhouse effect byproducing more carbon dioxide.  From thesource Nasa they state that other greenhouse gases include methane. 4,6            “Methane. A hydrocarbon gas produced both through naturalsources and human activities, including the decomposition of wastes inlandfills, agriculture, and especially rice cultivation, as well as ruminantdigestion and manure management associated with domestic livestock.”they committee that methane is a much more active greenhousegas than carbon dioxide but luckily it’sfar less abundant in the earth’s atmosphere.Another main greenhouse gas is a Nitrousoxide that the article points out.

Nasa saysthat it is a very strong greenhouse gas “produced by soil cultivationpractices, especially the use of commercial and organic fertilizers, fossilfuel combustion, nitric acid production, and biomass burning”. Nasa also pointsout Chlorofluorocarbons (CFCs) as being another contributor to the greenhousegas effect. The source of these CFCs isorigins is completely human, and they are very good at destroying the ozonelayer. Which is a layer in the atmospherethat protects us humans from dangerous cosmic rays in the first place. the increased rate of these greenhousegases being released into the atmosphereis mainly man-made. The thing that causesglobal warming is human activity.8″theIntergovernmental Panel on Climate Change, a group of 1,300 independentscientific experts from countries all over the world under the auspices of theUnited Nations, concluded there’s a more than 95 percent probability that humanactivities over the past 50 years have warmed our planet.”8The evidence thathumans cause global warming is responding.

From NASA they say that “atmosphericcarbon dioxide levels from 280 parts per million to 400 parts per million inthe last 150 years.” And that panel of scientistalso say the “human-produced carbongreenhouse gases… have caused much of the observed increase in Earth’stemperatures over the past 50 years”. How do we know it’s human-made. In the NASA article, they say             Theplanet’s average surface temperature has risen about 2.0 degrees Fahrenheit(1.1 degrees Celsius) since the late 19th century, a change driven largely byincreased carbon dioxide and other human-made emissions into the atmosphere.Most of the warming occurred in the past 35 years, with 16 of the 17 warmestyears on record occurring since 2001. Not only was 2016 the warmest year onrecord, but eight of the 12 months that make up the year — from January throughSeptember, with the exception of June — were the warmest on record for thoserespective months.

Whyis global warming such a concern?WWF says” Burning fossil fuels, such as coal, oiland natural gas, to generate energy has the greatest impact on the atmospherethan any other single human activity.” They support this statement by stating “Globally, power generationis responsible for about 23 billion tonnes of CO2 emissions per year – inexcess of 700 tonnes every second. Coal is especially damaging to ouratmosphere, releasing 70% more carbon dioxide than natural gas for every unitof energy produced.”15 So humans cause global warming and thebiggest cause of it is our burning fossil fuels for energy so we canbetter our lives. However, the cost of bettering ourlives is much more than the electricity bill. Economically the cost of theearth getting hotter could cost the planet about $21 trillion by 2050 saysJohnston of the independent.  Anotherproblem of climate change is that “crops, natural vegetation, anddomesticated and wild animals (including seafood) that sustain people in agiven area may be unable to adapt to local or regional changes in climate.” StatesRiebeek of the earth observatory department at NASA.

8Another majorconcern is that Ice sheets are melting. Live Science says that “The icesheets have been retreating since the end of the last Ice Age about 11,700years ago, but the last century’s warming has hastened their demise.”4 A 2016 study found that there is a 99% chance that it was global warming thatwas causing the accelerated demise of the IceSheets. Infect the study found that Glaciers( rivers of ice) retreated 10 to 15times the distance if climate change wasn’t a thing. But what’s the big dealwith melting ice? The problem is that itcan cause a lot of human life. “The loss of glaciers can cause the loss ofhuman life when icy dams holding back glacier lakes destabilize and burst, orwhen avalanches caused by unstable ice bury villages,”says Live Science.

The problem isn’t just with ice getting hotter its hot dryplaces getting hotter and drier. 4″The Southwest and Central Plains of the UnitedStates, for example, are expected to experience decades-long”megadroughts” harsher than anything else in human memory. “Thefuture of drought in western North America is likely to be worse than anybodyhas experienced in the history of the United States,”Benjamin Cook, a climate scientist at NASA’s Goddard Institute for SpaceStudies in New York City who published research projecting these droughts in2015,” Live Science reports.Live Science says in theirarticle is that “Subtropical regions, including the Mediterranean, theAmazon, Central America and Indonesia will likely be hardest hit, that studyfound, while South Africa, Mexico, WesternAustralia and California will also dry out” this obviously going to destabilise the ecosystems that live there in anegative way.

Another major concern is extreme weather. These tropical storms are bad for everyone involved.            “extremeweather, made worse by climate change, along with the health impacts of burningfossil fuels, has cost the U.S. economy at least $240 billion a year over thepast ten years, a new report has found. And yet this does not include this pastmonth’s three major hurricanes or 76 wildfires in nine Western states.

Thoseeconomic losses alone are estimated to top $300 billion, the report notes.” States TheNational Geographic.5In the article that Live Science produced they say that withthe planet increasing in temperature hurricanes and typhoons are going to getworse. This is because the oceans will evaporate more moisture. A large amount of moisture above oceans is whatcause these elements of mass destructionin the first place. “The International Panel on Climate Change (IPCC)predicts that even if the planet diversifies its energy sources and transitionsto a less fossil-fuel intense economy (known as the A1B scenario), tropicalcyclones are likely to be up to 11 percent more intense on average.” This means more destruction especially tothe coastline of countries on the coastline.

Another very bad problem is the acidificationof seawater.            “Oceans act as a carbon sink —they absorb dissolved carbon dioxide. That’s not a bad thing for theatmosphere, but it isn’t great for the marine ecosystem. When carbon dioxidereacts with seawater, it leads to a decline in pH, a process known as oceanacidification.

“Ocean acidificationis a very bad thing as it will affect the fish and therefore the millions ofpeople who rely on it for food and as their income. What can humans do to tackle climate change? On Individual bases there are a lot of people inthe first world country can do, as they are the highest contributors of greenhouse gases per capita. The best way to stopclimate change is to stop doing what’s causing it in the first place which is realisinggreenhouse gases into the atmosphere. According to a study referenced inPopular Science the things that reduce your Co2 footprint the most are; “having fewer children; living withouta car; avoiding transatlantic flights; and eating a plant-based (mostlyvegetarian) diet.”12 To really drive this point the articlepoints out that “swapping out your lightbulbswould reduce CO2 emissions by less than .2 tons per year. Living car-free, however? That reduces your CO2emissions by more than 3 tons.

Having one less child reduces climate changeimpacts by 120 tons of CO2 emissions per year” says Popular Science.Another way to reduce co2 emissions drastically is to just unplugdevices.            “an average load for a home in the U.S.

Audio and videodevices, cordless vacuums and power tools, and other electronics use energyeven when they’re not charging. This “idle load” across all U.S.

households adds up to the output of 50 large power plants in the U.S. So don’tleave fully charged devices plugged into your home’s outlets”9reports the NRDC.Going vegetarian as well is normally concerned a way to reduce a personcarbon footprint. This is because as I fond out in Biello’s article is that “Universityof Chicago researchers estimate that each meat-eating American produces 1.5tons more greenhouse gases through their food choice than do their vegetarianpeers.”1 If you also take into account that it would cost a lotless land to grow crops than it would raise animals, you are looking at prettysure fire way to reduce your carbon footprint.

However, in the same article, it does point out it’s not thatsimple. This is because as said in the article “Corn grown in the U.S.requires barrels of oil for the fertilizer to grow it and the diesel fuel toharvest and transport it.” And the corn is normally shipped from around the world so.

Going vegetarianisn’t as green as it appears but its still better than eating meat.
