i need to have 3 changes to the landscape that global warming creates,

i have:

ocean levels increase because ice caps melt,

and islands are discovered,

can anybody think of anymore!?

anything would be helpful please and thankyuo! (L):)

  1. I'm not sure what you mean by islands being discovered?

    Islands that were under the ice?

    The ocean rises not just because of things melting but because warmer water occupies more space than colder water.

    The rise in water would cause flooding.

    Salt water would go further upstream into freshwater rivers making them salty.

    Glaciers and ice on the tops of mountains are also melting.

    Lack of rainfall causes drought which can lead to loss of vegetation.


  2. its hot

    the ozone is thinner

    green house gasses are more popular so bad air quality

  3. "Rising sea levels, glacier retreat, Arctic shrinkage, and altered patterns of agriculture are cited as direct consequences, but predictions for secondary and regional effects include extreme weather events, an expansion of tropical diseases, changes in the timing of seasonal patterns in ecosystems, and drastic economic impact."

    Good luck! Sounds like a fun topic =)

  4. YOU ALREADY PRESENTED DUH! wait this was 20 ours ago you posted this

    opss lmao

    ANY WAY IT WAS 10 MIN LMAO EHHELOVE YOU LOVE YOU (L)(L)

  5. coast lines change with rising ocean levels

    more arid /dessert areas because of heat

  6. 50% of humans live within 50 miles of an ocean or sea. Flooding is a major change comming as earth tries to rebalance GW. Today here is what we know:  many of mankind’s advancements cause earth surface to warm, destroy the ozone layer, kill off endanger species, heat cities, and in some way cause more destruction.  Blacktop (roads and parking lots), buildings, air pollution (causes lung and other diseases), deforestation, duststorms (which increase hurricanes and cyclones and cause lung diseases), fires (cause pollution, mud slides, and deforestation), refrigerants (like CFC's), solvents (including benzene destroy the ozone layer raising skin cancer rates) and plastics; cars, airplanes, ships and most electricity production (causes pollution including raised CO2 levels) are human problems we need to fix to keep life on earth sustainable! That is why I founded CoolingEarth.org, a geoengineering web sight. The federal government needs to adopt a pollution surcharge to balance the field and advance new technologies. We must pay the real price of oil (petrochemicals) including global warming, cleanup and for health effects. But with that we must understand we have never seen what is now happening before. CO2 has never lead to temperature change, but temperature change has led to increases in CO2. The models have to be made as we go along with little evidence! The result is:  change is on the way, we just do not know what changes. But again adding a small amount of CO2 to the atmosphere enlarges the earths sun collection causing warming; increase water in the atmosphere and they form clouds cooling earth but causing flooding. Even natural events are warming earth and causing destruction. The sun has an increased magnetic field causing increases in earthquakes (more destruction), volcanoes (wow, great destruction), and sun spots. Lighting produces ozone near the surface (raising air pollution levels). But humans have destroyed half of the wetlands, cut down nearly half of the rain forest, and advance on the earths grasslands while advancing desertification which increases duststorms. The USA Mayor's have taken a stand and I believe are on the right track, we can have control and can have economic growth. With the peak of oil in the 1970’s, the peak of ocean fishing in the 1980’s, humans must stop procrastinating and make real changes to keep earth sustainable including in the energy debate, finance and regulation. The sun is available to produce energy, bring light to buildings and makes most of human’s fresh water. Composting is the answer to desertification. New dams are the answer to fresh water storage, energy and cooling earth by evaporation, we need many small one all over (California needs 100 by 2012 and has not even started).

    President Bush has made a choice of energy (ethanol) over food and feeding the starving people around the world; this is a choice China has rejected.

  8. lmfao.!!!!

    NOW I FELL BAD AGAIN ABOUT THE PURFUMML:(:( wait to go jordyn!! lmao not that easy looking for a art historian do you even know whta that means? LOL theres absoulutly nohting on google thats y im asking this LMFAO.

  9. ummmm ya theres floods

  10. the only way the sea level will rise is if the glaciers that melt are land locked

    if the glacier is free floating, then it is already displacing all of the water that it can. its kinda like ice in a glass of water

  11. Starting with melting ice, changes to the "landscape" (and "oceanscape") might be:

    1. Extreme melting of the ice cap can create new ocean channels for shipping and boating.  Note that this melting occurs seasonally and is different every year.  Last year's melting was easily the greatest ever seen.  (see the reference link for great sea ice info)

    2. Warming leads to an increase in the break-up of of the earth's glaciers and ice shelves which also leads to an increase in the number of icebergs in the ocean.

    3. Increased melting of of ice also creates more runoff which can lead to an increase in localized flooding events and an increase in erosion and dispersal of sediment.  

    4. Reduction in ice coverage also reduces the earth's solar reflectivity which means that that the planet will absorb more sun energy via the ocean or land, further increasing warming.  Reduced solar reflectivity can also be caused by a darkening of the ice due to less snow and/or an increase in deposition of dust due to more particulate matter in the air (possibly from increase in desertification and/or industrial "soot")

    5. Don't forget about the melting Tundra!! This is a layer of dirt and plant matter that is frozen upon which many plants and animals live (including people).  When Tundra melts it usually becomes a muddy bog. (side note: melting Tundra may also emit lots of Methane gas which is much more effective as a "greenhouse gas" than the now famous carbon dioxide. )

    Other changes to Landscape:

    6. When you think of "landscape" it could be mountains, rivers, lakes, deserts.  These things change relatively slowly over time (e.g. erosion of rock, the slow change in the meanding of a river). However, landscape can also change due to changes animal and plant behiavior.  Most plants grow narturally in a certain "niche" because of the local climate (sun, water, soil content, competition, predators, seed dispersal). Imagine what happens when that "niche" changes . . . plants species might survive or die . . . or they may seemingly "migrate" to another location, which could result in a drafsic change in the "landscape".  For instance, alpine forests may appear to move higher in elevation (because the temperature zones are shifting due to warming).  Also any animals that depend upon certain plants envioronments could move or simply die off.

    7.  Animals also affect the landcape. From Elephants and water buffalo to insects and bacteria, animals have been changing the earth's lanscape since the beginning of life itself.  For instance, a large herd of mammals could adapt to changes in the availability of water and drastically alter their migration routes.  The new routes would be subject to grazing, trampling and waste matter.  This is not necessarily "bad" but will change the landscape from perhaps a "brushy" area to a "grassland".

    Just remember that the climate has always fluctuated.  It just appears to be happening faster these days than in the past.  A big volcanic event or comet collision could produce very drastic effects. Perhaps you could use one those scenarios to stimulate other ideas . . .
