need some help please

hi i am doing a project in school on global warming. i'm trying to find an image of earth with heightened sea levels but with no luck so far. if someone could help me out it would be greatly appreciated. thanx, tetchy

How about this, grida.no ?

thank you very much. that site has a lot of info. sound.

The movie (and now the book of the same name) by Al Gore includes many graphs, photos, as well as several illustrations of how coastal maps would radically change as ocean levels rise due to climate change. The book is:

An Inconvenient Truth, by Al Gore. 2006 Rodale Press. $21.95 325 p.

When the movie premiered in May 2006, moviegoers were directed to a related web site for much more information and news updates. That site is:

www.climatecrisis.net...


Your local public and/or college library will have this book. Or you can buy it at a 10% discount with a Barnes & Noble bookstore membership if you shop at the physical store.

Another critically acclaimed new book (2006) on this topic is "Field notes from a catastrophe" by Elizabeth Kolbert, the former New York Times reporter.

You can get much more expert and free help on this topic by contacting (either in person, by phone, via e-mail or instant message) your local public or college library's Reference Desk staff (also often called Information Desk, Information Services, etc.). Good luck, and let me know how the search goes.

first off all thanks to sanctum and librarian for their help. but one thing i dont understand: why arent these maps and graphs availible freely. surely the best way to get the point across would be to show people what the world would look like if these things happened for real, rather than saying " the world's oceans will rise by 4 meters". (who can picture that properly without an illustration)

Heres somethin:

Try this too...

The following link will give you free options in display of various scenarios of ocean level rise in North America:

www.climate.org...

In the 2006 book version of An Inconvenient Truth (by former U.S. Vice President Al Gore), pp. 194-209 show the following scenarios:

Actual data from 1992, 2002 and 2005 showing the rapid acceleration of glacier melting on Greenland.

The shoreline changes were shown for Florida, for San Francisco Bay, for The Netherlands, for the area around Beijing, for the area around Shanghai, for the areas around Calcutta and Bangladesh. Also, for Manhattan Island, we see that the new World Trade Center Memorial and its surrounding area will all be under water.

So the good news is that these maps are shown in the book. The bad news is that source information is limited to the following credits in the back of the book:

Renewable Films/ACIA (for the 3 graphs of Greenland),

MDA Federal Inc. and Brian Fisher/Renewable Films (for the enhanced satellite maps of Florida, of the San Francisco Bay, and for the Netherlands).

Ooms Averhorn Groep bv (for the remaining enhanced satellite maps).

Unfortunately, this book currently lacks an index or glossary, and does not even have a table of contents. Thus its origin as a multimedia slide show is still obvious.

Since you are in Ireland, I recommend you phone, e-mail or send an Instant Message request to your local library, in order to avoid having to pay for additional resources on this topic. Ask the librarians what satellite information and government maps they have access to which address the important topic of climate change.

Finally, here is a link to a news summary reporting an opinion from a leading UK scientist that global maps "will have to be redrawn" after climate change.

www.countercurrents.org...

The other way to approach this topic would be to examine a topographic map (available for free in libraries) and make a photocopy that you can mark off in pastel colors where you expect that coastlines would be impacted by increased ocean height.

Also check out web sites affiliated with the United Nations. They have a great deal of free information, such as the following:

unosat.web.cern.ch...

Finally, on the subject of free information online, keep in mind that much of the high-value information that can be accessed on the internet is not free. Online magazines often charge a subscription fee, for example. For map information, therefore, your best source of free and accurate information would be government sources; the British Museum has some information online for libraries, so that's another possibility. Aside from the question of "free or fee", much of the information online has been created by commercial entities -- consider for example, that if you were to do a Yahoo! or Google search on the term 'flowers", over 80% of the search results would retrieve web sites which are associated with flower seller companies. Less than 10% of all online information has been provided by educational institutions. What's a student to do? 'Be careful out there', and check your results with a librarian.

hi all. glad i registered here now. lots of info here. thank you.

I found a search term which yielded more specific information on shoreline changes due to global warming. That term is "sea level rise" which you can also use in library database searching: For example, all libraries now have large databases of information online which can only be accessed either within the library or outside of the library via a library card ID number.

A book review of a scientific book published on this topic in 2000 is at the following link:

cerf-jcr.org...

A teaching plan for 6th thru 8th grade students, guiding them through an exercise in understanding sea level rise through marking changes on topographic maps (such as I recommended to you before) is available at:

cerf-jcr.org...

Finally, Wikipedia, the free online encyclopedia, has a 16-page section on sea level rise. Librarians currently recommend using Wikipedia on a "trust but verify" basis, since there is currently no way to be certain of the level of expertise of the volunteers who create the many Wikipedia sections. Here's that link:

en.wikipedia.org...

In particular, go to the Wikipedia section titled "External Links", and click on the link titled "interactive sea level map", and you will arrive at a web site which allows you to change the amount of sea level on a map and directly see the effects of those changes. Again, in order to be assured of the accuracy of this information, get verification from a bona fide academic or government source.

Other resources include the following:

www.maptech.com...

They are "the largest online mapping resource for topographic maps and charts for land, sea, and air. Browse, view, print, and email the maps for free."

www.topozone.com...

(I don't know if topozone is free or not.)

Finally, the world sites atlas is at:
