The effects of global warming can be both positive and negative.
Global warming is caused by greenhouse gases in the atmosphere that trap radiation from the sun and keep it from being released back into space. This is causing the temperatures in many places on Earth to rise by a few degrees. This may not seem like much, but in colder regions like Alaska, Canada, the North Pole, Nova Scotia, and others, this slight temperature difference has a big effect. Scientists speculate that if the current warming trend continues, the polar ice caps will melt and many other environmental changes will occur that can be both good and bad for all life on Earth.
A global temperature increase means less energy used to heat homes and buildings during winter months, but it also means warmer temperatures for bacteria, viruses, and other organisms to thrive, leading to a possible increase in various diseases and medical conditions. Deaths and illnesses caused by cold weather will decrease, but deaths caused by hot temperatures will increase, so there may not be any more or less fatalities. In cold weather, shoveling snow and other activities can increase the risks of heart attacks and other medical problems that can cause death or injury, like frostbite or hypothermia. In warmer climates, health dangers such as heat strokes and dehydration are more prevalent.
Global warming could cause weather patterns and conditions to change, creating storms in new places and allowing super storms and hurricanes to appear. These storms could be deadly and may be much stronger because of global warming. On the positive side, plants, trees, and other living elements on Earth will flourish, just like they have throughout history when the Earth has warmed up after an ice age. More trees and plant life means more oxygen released into the atmosphere and more carbon dioxide being absorbed since plants require carbon dioxide to perform photosynthesis.
Global warming could have some positive financial benefits. Many northern areas might save millions of dollars each year on snow and ice removal from the roads, not to mention the repairs made on roads every year due to freezing and thawing, which creates potholes and large cracks in pavement and asphalt.
Global warming has both negative and positive aspects, but this does not mean that steps should not be taken to conserve energy and use renewable energy sources such as biomass energy. These two methods can help prevent the negative impact that global warming has on the Earth by minimizing and eliminating fossil fuel pollution that contribute to global warming, thus helping make the Earth a better place for all.

You talk about the pros and cons of global warming, but what many people do not realize is that based on scientific research that is being done today, global warming is not having as big on an impact as scientists and researchers want you to believe. It's a very slow process that melts polar ice caps thousands of feet thick. Think about it.
February 3, 2009 at 16:41 pmGlobal warming has always been something that concerns me. Take a look at the polar bears for instance. They are going exstinct right before our eyes and they are just one of the many species that are being affected.
February 6, 2009 at 08:48 pm"Deaths and illnesses caused by cold weather will decrease, but deaths caused by hot temperatures will increase, so there may not be any more or less fatalities." - It's funny how you can equalize this. Can this be counted somehow?
February 6, 2009 at 15:02 pmTo fay: Hurricanes are getting stronger year after year. If this is too slow for you than probably you have never seen how devastating this can be
February 6, 2009 at 15:12 pmLiving in a Northern State I would welcome the thought of not having to have winter months where the tempurature stays below freezing for days on end. BUT honestly I would rather live through it than to see the devistation that global warming can cause on certain things.
February 6, 2009 at 21:04 pmLizzie I too live in the northern US and right now I would trade this freezing cold weather for just about anything, but trading it in so that several species can perish is not an option I want to consider.
February 7, 2009 at 08:46 pmHonestly I think the cons of global warming highly out weight any pros that anyone can come up with. Global warming is effecting so many different species of not only animals but plants, bacteria and many more things. Are we really that selfish that we can say that these cons can be turned into positive things?
February 8, 2009 at 09:26 pmHave any of you ever seen 'The Day After Tomorrow'? I definitely do not want that to happen! Although, it seems that we have no control over global warming..
February 10, 2009 at 12:22 pmIt already seems like we are seeing many of the effects of global warming. From the harsher storms all the way to the terrible winter months.
February 10, 2009 at 12:23 pmKal, the human race acutally does have some control. We control the speed in which global warming is happening by belching filth into the atmosphere from our cars and other vehicles. That is why it is important that websites like this keep promoting alternative methods.
February 23, 2009 at 12:44 pmResponding to "fay" of Feb. 3: the Arctic ice cap is only 3 feet thick now, down from 10 feet in 1991. It has lost 50% of its volume since the 1950s. The fact is that climate scientists are not trained as communicators nor comfortable being political, but most of them are amazed at how little their dire warnings are heeded. Vested interests in the fossil fuel industries, and their conservative radio friends, have done a lot of harm by spreading misinformation. Climate change is the greatest threat facing humanity. Too bad we wait until a crisis actually happens to do anything about it.
March 7, 2009 at 22:40 pmi think that global warming is taking its latest stance on our economy and our future. i think that the life loss will increase for two reasons:heat related causes, and mosquitos are able to live longer and carry more dieseas if you agree with me then send me an email at: mrwatchout@gmail.com
March 11, 2009 at 10:11 pmNo... arctic ice is now 50 feet thick up from just 3 inches thick. I say it, so it is so.
March 16, 2009 at 18:10 pmPros: by trying to stop global warming we also learn more about technology and scientific advances can be made. Also CO2 fertilization increases the efficiency of water use in some plants. The travel time from Europe to America will be reduced by 1/3. There are more but I can't think of them at this moment
April 7, 2009 at 14:56 pmCons: the cons are that all the water from the ice caps will melt and flood the world. Also the heat will wipe out a lot of animals and plants that are sensative to heat.
April 7, 2009 at 15:01 pmcons:the next ice age is scheduled to come in 2,000 years but global warming is speeding that up!!
May 1, 2009 at 15:35 pmI am doing an persuasive essay on global warming and going against the fact that its real; and there is no good info against it
May 20, 2009 at 16:29 pmGlobal Warming is fake the communists created it to kill us
May 21, 2009 at 17:20 pmanastasiya, Cons: the cons are that all the water from the ice caps will melt and flood the world. Also the heat will wipe out a lot of animals and plants that are sensative to heat. No, just no. The world will not be flooded, in fact, global warming will create MORE usable land mass. If you only took the time to think about what you post you would have seen this. Take a look at a globe, how much of the world's current land masses are below the equator compared to above it? Right. Since so much of our land mass is in the North, where temperatures are colder, global warming is a good thing. About 20% of Canada is under permafrost, and an even higher amount is still unusable because while it may not be under permafrost, it never warms up enough to be useful. The same argument can be made for northern Russia, Greenland, etc. Now those are some massive landmasses we're talking about here. Global warming will make these lands easily available for agriculture and will make them habitable for animal and plant life. It's also worth noting that these land masses are (thankfully) in developed countries who have the necessary resources to be able to seize this opportunity when it presents itself.
May 27, 2009 at 19:54 pmWell global warming is not really a man probably, the earth has been cooling for the past 11 years so naturally it will heat up again, trying to do something about it is going to probably trigger the next ice age. Here's something to think about, greenhouse gases are CO2 and when you breathe what do you exhale, CO2 so shouldn't the earths population be wiped out? Believe it or not some extreme liberals think that the earths population should be wiped out. Al Gores silly documentary seemed pretty convincing right? Only on account of that his whole film was based off of charts and graphs well last time I check Al Gore is not a climatologist or a meteorologist he's a politician.
May 29, 2009 at 11:55 pmUmmm... did you know that the artic may have its first ice free summer by 2030 or earlier because of global warming! :S
June 6, 2009 at 12:11 pmand we could have no Antarctic by 3050
June 25, 2009 at 02:05 pmi dagum hate global warming its alredy hotnenough in the south as it is!!!:)
October 7, 2009 at 13:53 pmis this pro or con???
November 20, 2009 at 13:49 pmwell, i think global warming is a good thing....i mean now i can go to the beach more often
December 2, 2009 at 12:50 pmwell, i think global warming is a good thing....i mean now i can go to the beach more often, also i dont have to shovel that annoying snow off my drive way. not to mention global warming can get rid of all those annoying polar bears, their eating our peguins. Also china will have a reason to stop driving so many cars at the same time...no offense but their are way to many people over there. And one more question....why won't my parakeet eat my diarrhea, is it because global warming is getting it down, or does it not eat my diarrhea because it doesn't like hard poop?
