Humans and climate is what I've figured out so far, any more info or more detail would be great...thanks

You would be right in saying humans.\n\nThe Holocene includes the last 10,000 years of earth's existance also known as the "age of man".\n\nThis extinction, I believe, includes a little time prior to the Holocene called the Pleistocene.\n\nMammoths, saber-toothed cats, ground sloths, & North American horses were included in this extinction as well as many others but these are the most well known.\n\nAt this time, the climate was changing, as it still continues to do today. However, it was dramatic enough to affect native species.\n\nSo you are right on both counts actually.\n\nOverhunting/killing by increase in human population & the climate changes.

GLOBAL WARMING!!! this is a big issue. you could research a lot on that. or you could do the war in Iraq.

If you really want a global overview and want to get a handle on weather causes, you should delve into the Weather Blog at http://360.yahoo.com/ki_te_moana\n\nDo not forget to pull up the urls in the Blog Roll and the ones that appear in the articles and in the blast.  Save the ones you find interesting.\n\nThe Atmosphere and the Oceans are intimately related weatherwise.  If you are not interested in that relationshi;p, you will never get a handle on what you want.\n\nThere are lots of answers to Weather Questions in my Answers.  If you start clicking things off a little at a time the complete picture will start forming eventually.\n\nMuch easier to do in the ara of Satellite Views over the Internet than it was 40 years ago.

although global warming is real and its effects are already being measured in a variety of systems in the world, it is being a little too hasty to assume that the warm weather in Florida (and across a lot of the US, for that matter) is caused by it.  Weather is virtually an infinitly variable system, so predicting or proving causality for a single effect is very difficult.  I think that should have been the ultimate warning for those who scoff at the idea of human-influenced global warming- we simply can not determine the long (or even short-) term effects of human activities on the earth once those activities reach a critical mass of influence (which they have) Basically, we are screwed...

humans- stress,health, emotional effects, financial effects, humanity comes intoplay here with people helping people\n\nenviroment- new growth, polution(the ash in the sky), migration of wildlife(have 2 move to find food),

We do not have enough scientific data to show that the current warming cycle is being adversely affected by man.  The sun is the source of global warming.  It always has been.  Weather, on our planet, has been changing for 5 billion years.  Scientists have at most 100 years of temperature data to look at.\nLook at the weather in Northwestern Pennsylvania from 1976 to 1978.  I was there.  During one winter, there were record snow falls.  During the next winter, there was record cold.  People were looking for the start of an ice age.  \nOur weather changes every day.  It will continue to change every day.  Until man has infinite knowledge, which will be never, man will never be able to factor in the endless number of possibilities that affect climate.  Several months ago, I watched a program on PBS wherein scientists were claiming that global warming was causing surface cooling.  I got a head ache and shut it off.

Global warming is happening, make no mistake about it.  This natural cycle that we're going through seems to be accelerating.  Is it due to humans?  Quite possibly.  Can we do anything about it?  Maybe, but will it have a dramatic effect?  Who knows.\nNobody in their right mind believes we are going to "destroy" the planet.  At worst we'll just make it uninhabitable.

PLEASE PLEASE PLEASE!  Once again, CFCs have no effect on global warming.  Please get this muddle corrected.\n\nAs for your question:  The best guess is that one third is "natural" and two thirds are human caused

Actually, global warming would lead to stronger storms which make larger hail. I think this idea you have said about hail decreasing in size over time is wrong because it doesn't make much sense.

The topic is very vast. You could try this strategy: select major countries along the Equator, like Brazil, Equador, African countries, etc. and find information on these countries: agriculture, people, etc. This will help you find all the information you need. \n\nTry also these links, if you want:\n\nClimate and vegetation : http://www.scalloway.org.uk/clim9.htm \nhttp://www.meteorologyclimate.com/Equatorial-climate.htm\n\nDisasters: http://www.unescap.org/mced2000/pacific/background/disasters.htm\n\nhttp://en.wikipedia.org/wiki/Equator

Everything on Earth affects the climate, including its human inhabitants. Just by breathing we add carbon dioxide to the air, which in turn affects climate patterns. And, of course, humans create machines that add pollutants to the atmosphere and we disrupt the climate every time we drain a swamp or otherwise make nature do something different.\n\nHowever, the Earth's climate has undergone many dramatic changes over its four-billion-year lifespan, and none of them had anything to do with humans. So, while humans are a part of the process, climate change is itself a natural occurrence.

I think the weather channel has information like that. check their site. Or put it on search online and you may come up with some hits or leads.

Neat how the graph excludes prior dates.  20 years ago it was global cooling.\n\nThe temperature varies, greenhouse gasses come from natural occurrences (Krakatoa and Mt. Saint Helens spewed more greenhouse gasses in the air than man has produced in 10,000 years).  The earth recovers.  Liberal activists don't.

Aalexart put the case extremely well, and has obviously like me read several books that have no bias.\nThe site below will help you, the presumptiousness of man that we can influence the weather. King Canute had more success with the tide.\nYes we are gradually returning to the climate pre the mini ice age, but we still have a long way to go.

The above is a good data source - browse around and you may find others. Each NWS office has climate data at thier site, and state climatologists also have some.\n\nAfter you get the data though, how do you plan to compute the average? I.e., suppose you get the data for each state. Many locations are at airports near cities which are lower than the average elevation in the state. The climates at some are affected by proximity to the Great Lakes, oceans, or mountains - some are deserts, others are wet. A simple average of data from all locations would show something, but be biased toward highly-populated areas. Seems to me the best way to proceed if you want a really accurate calculation is to weight the data for each state according to location (not easily done), then the average for each state according to area. Maybe someone already did something similar and has that information. I suggest to search for that sort of thing first, then check to see if their method seems reasonable and accurate. I do not know who has done that - could even be somewhere here:\n\nhttp://www.cpc.ncep.noaa.gov
