what are the many things that will change with global warming?

Answer 1

RISING TEMPERATURES
The most extensive report into climate change and global warming was conducted by the IPCC and concluded that temperature rises of between 1.8°C and 4.0° should be expected by the end of the 21st century http://news.bbc.co.uk/1/hi/sci/tech/6324029.stm
 
HEALTH IMPLICATIONS
In 2007 one person is dying every three minutes as a result of global warming, this figure is expected to double by 2020 http://www.planetark.org/dailynewsstory.cfm/newsid/22420/story.htm The World Health Organisation (WHO) predicts that rising temperatures will result in an additional 300,000 deaths and 10 million illnesses a year by 2030 http://www.washingtonpost.com/wp-dyn/content/article/2005/11/16/AR2005111602197.html . This is in addition to the tens of millions of additional cases of malaria that the WHO expects to see http://www.ecobridge.org/content/g_tht.htm#Diseases
 
ECOLOGICAL IMPACT
A quarter of the species of animals and plants could be extinct by 2050 http://news.bbc.co.uk/1/hi/sci/tech/3375447.stm . More than three million square kilometres of Arctic sea ice has melted threatening the habitat of polar bears, experts predict that their numbers will ‘plummet’ http://www.washingtonpost.com/wp-dyn/content/article/2005/07/06/AR2005070601899.html ; the survival of grizzly bears is also threatened http://www.y2y.net/grizzly/modelling.asp . Other species that are threatened include penguin, turtle, caribou, walrus, plankton, krill, whale, crab and seal http://www.ecobridge.org/content/g_tht.htm .  

ADVERSE WEATHER
In recent years there has been an 80% increase in the number of category 4 and 5 hurricanes. Along with cyclones, tornados and other storms the frequency looks set to keep increasing http://www.sciencemag.org/cgi/content/full/309/5742/1844/ . The UK Met Office predicts a nine-fold increase in the extent of flooding within the next 50 years http://www.metoffice.gov.uk/research/hadleycentre/models/modeldata.html .
 
In 2003 a heatwave in Europe, one of many in recent years, claimed up to 50,000 lives http://en.wikipedia.org/wiki/European_Heat_Wave_of_2003 , predictions are that the annual number of heat related deaths will increase significantly http://www.ecobridge.org/content/g_tht.htm#Waves .
   
DROUGHT AND FAMINE
The heat is likely to greatly increase the number of forest fires, reduce timber production, impact on agricultural land and lead to more insect infestation which in turn impacts on crop production and human health http://www.ogc.doc.gov/ogc/legreg/testimon/106s/karl0718.htm .
 
Rising temperatures have a huge impact on food production, a 1°C rise equates to a 10% loss in grain production, areas already facing food shortages will be hardest hit http://www.ens-newswire.com/ens/jan2001/2001-01-22-02.asp . Warmer temperatures create severe drought conditions; billions of people will be affected by contaminated water, a lack of water or both http://www.unesco.org/water/wwap/wwdr/pdf/chap4.pdf , in China and south east Asia alone hundreds of millions will be affected http://www.abc.net.au/news/newsitems/200503/s1322814.htm .
 
RISING SEA LEVELS
Rising sea levels have already impacted hard on many island and coastal communities including the forced evacuation of their populations. Areas affected include Kenya, Kiribati, Marshall Islands, Tuvalu, Bangladesh, Papua New Guinea, Micronesia, Maldives, Antigua and Bermuda http://www.ecobridge.org/content/g_tht.htm#States . Sea levels have been rising for some time and predictions indicate further rises of between 200 and 600mm by the end of the century. In the US this would affect many coastal regions especially the coastlines of Florida and the Gulf of Mexico, cities affected would include Boston, New York, Charleston, Miami and New Orleans http://www.ecobridge.org/content/g_tht.htm#cities .
 
OTHER EFFECTS
The effects are wide ranging, some are already happening and are expected to get worse, others are likely to happen with the severity dependent on how much the earth’s global temperature rises by.  

Some of the other impacts of global warming include: arctic warming, increased power outages, marine food chain disruption, changes to bird migration patterns, more wildfires, erosion, desertification, disappearing beaches, damage to tundra regions, impact on ozone layer, insect infestation, threat to boreal forests, coastal erosion, threat to mountain environments, loss of wetland and marshland habitats, decline in bird population, thawing of permafrost, increased acidity of oceans, release of further greenhouse gases, increased allergens (asthma etc), coral destruction and bleaching, loss of ocean conveyor belts (Gulf Stream) etc, loss of Arctic sea ice, impact on winter sports.

Answer 2

Gradually coastal areas will start to flood. First in storms, then all the time. Changes to temperature and precipitation patterns won't affect humans much, but will severely damage agriculture.

Rich nations will be able to cope, but it will cost them huge sums of money and lower their standard of living. In poor countries already struggling to feed themselves a lot (not all) of people will die of starvation.

It will be the worst disaster in human history. It will take a long time to happen, maybe 20-50 years. But it will take even longer to fix the problem. We need to start right now.

Answer 3

Hmmmm....scientists say that we'll see major changes in 50 years, but meteorolgists cannot accurately forecast the weather more than 72 hours from now. So, now tell me how you think global warming is realistic.

Answer 4

Beach front property in Canada will increase in value and become a vacation destination.
