Increased agricultural productivity & land (more rain, warmth & Co2)
Longer growing seasons for all plant life
greening of some of the Earth's vast frozen land masses
increased Co2 absorption rate
added habitat for wildlife
More bountiful food for animal life
less food/energy requirements for animal life
Less net global energy requirement for humans
Less deforestation for heating fuel
Less cold related severe weather and death
Greater cushion against lower global temp. anomalies (little ice age only -1 or 2 degrees)
more pleasant temperatures for vast majority economic activity and outdoor activity/recreation
MOST IMPORTANTLY: if we are very lucky and warm enough, we may even avert the next ice age: Ice ages are not controversial ideas like global warming, they are real and acknowledged by all scientists regardless of political affiliation. They occur like clockwork, they appear very rapidly, with in a few human generations, and wipe out most animal and plant life on the planet.
Despite being anti-global warming myself, there are some benefits to it;
Business- Less restrictions on production means lower prices for the consumer
Water- The increase in water could end drought in developing countries and alleviate water restrictions at home.
Animal Life- Animals and birds may not need to migrate so far for water (and food as a consequence of the extra water)
Tropical Rain forests- Global warming could see these increasing
The benefits do not even come close to the drawbacks though.
I will now list the three major benefits of global warming.
- Fewer cold-related deaths. Many, many more people die from cold than from heat (though the cold related deaths don't get as much media attention). The warmer it gets, the fewer people will die from cold. Moreover, global warming models all predict that the coldest times of the year, the coldest times of the day, and the coldest parts of the world will warm much more than the warmest times of the year, times of the day, and parts of the world. So, the positive effect of warming in the cold areas/times will more than offset, by a huge margin in fact, the negative effect of warming in the warm areas/times.
- Increased food supply. Alarmists will tell you that global warming endangers the world's food supply. This is because they do not have a basic understanding of agronomic production. There are three things that crops need more than anything else to grow and produce high yields: heat, moisture, and carbon dioxide. Some crops can get too much heat, but even the worst predictions of global warming alarmists don't call for such temperatures. In most cases, increased temperatures will increase yields. Moreover, millions of acres that are now too cold to grow crops will become warm enough. Furthermore, in traditional crop-growing areas, it is entirely possible that, with a shorter, warmer winter, farmers will be able to plant their crops earlier and harvest them later. What this means is that they might be able to get two crops planted and harvested in one year, effectively doubling the yield. The case can be made that rainfall will decrease in some areas of the world if global warming continues. But overall, worldwide precipitation will increase. So we might have to shift farming to other areas (which is not a bad idea anyway) but there will be plenty of places where rainfall is adequate for growing crops. And even where it isn't, there's always irrigation. Carbon dioxide is obvious. Supposedly, it's the culprit behind global warming, so if global warming continues, it will be because of more carbon dioxide. But plants live on carbon dioxide - the more of it they have, the faster they grow and the higher yields they obtain. Greenhouse growers have artificially raised CO2 levels to several times current atmospheric levels, with no ill effects (and plenty of positive effects) to the crops. All in all, global warming will probably be the best thing to happen to agricultural production since the invention of the tractor and man-made fertilizers.
- Less Disease. The most common diseases, that kill far more people (at least in developed nations) than exotic stuff like malaria, AIDS, Ebola, etc., are associated with cold weather. In a technical sense, cold weather does not cause the common cold, flu, strepthroat, sinusitis, and pneumonia. However, cold weather does force people to spend more time indoors, in close contact with other people, and with limited ventilation. This is an ideal environment for diseases to spread from one person to another. Warmer weather would allow people to spend more time outdoors, where diseases cannot easily spread. As for the exotic stuff, the only one that anybody is really talking about being worse because of global warming is malaria. They claim malaria is a tropical disease, and that as tropical temperatures spread, so will the disease. But malaria isn't tropical at all. A hundred years ago, its range was limited only by the range of its carrier, the anopheles mosquito, whose range was pretty much worldwide. And then all of the developed nations eradicated the anopheles mosquito (with DDT), thus eradicating malaria. If, for some reason (not global warming), the mosquito (and the disease) made a comeback, it could be eradicated again, with more DDT. Not. A. Problem.
If you look at global warming as the alternative to
stopping global warming, then you could also list all of the disadvantages of stopping global warming as benefits of global warming itself. For example:
- Freedom. Stopping global warming will force the people to hand over their rights and freedoms to an all-powerful government. This is indisputable. We will have to give up our right to drive cars, our right to electricity, our freedom of enterprise, and our right to anything else that involves the burning of fossil fuels. And we will even have to give up our freedom of speech, because, in the name of saving the planet, the government cannot tolerate any skepticism about global warming.
- Prosperity. Stopping global warming (if the alarmists are correct about its causes) will require a ban on (or at least a massive reduction in) the burning of fossil fuels. Fossil fuels are what drives our economy. Without them, everything will grind to a halt quite quickly. Businesses will fail. Jobs will disappear. The economy will go into the tank.
- Human comfort, convenience, and entertainment. One of the rights we will have to give up is the right to use electricity. We won't be able to use our stoves, our lights, our air conditioners, our heaters, our dishwashers, our hot water heaters, our televisions, our computers, etc. Are those things that you want to do without? Can you even survive without those things?
- Food supply. I've already mentioned how the food supply will increase dramatically under global warming. But any effort to stop global warming will cause a huge decrease in the food supply. Growing crops requires tractors, and tractors use fossil fuels. Except they won't be using fossil fuels anymore if we are going to stop global warming. Tractors will be replaced with mules and other draft animals. Not only will agricultural production drop by 80-90%, but much of what is left will be required to feed the draft animals. And what little food is grown will never make it to the places where people live in massive numbers because that too requires burning fossil fuels. There will be massive starvation around the world, especially in large urban areas and other places where no food is grown.
- World Peace. We already know that China and India are never going to go along with reducing their carbon dioxide emissions. But no plan to stop global warming will work without their participation. So what are we going to do about that? We're going to go to war with them, that's what we are going to do. The Arab nations will ally themselves with China and India, because that will be the only customers they have for their oil. The two sides will be fairly evenly matched, which will make for a very long, very bloody world war. There will be tens of millions of deaths over years, perhaps decades, in this World War III, caused by global warming alarmism. Not to mention that the war will defeat its own purpose anyway, because of the massive burning of fossil fuels that will be required to wage that war.
- Avoiding Worldwide Nuclear Armageddon. It is very, very likely that the WW3 mentioned in the previous point will, eventually, go nuclear. Then everything is for naught. Oh sure, global warming will be stopped, because of the planet-covering cloud of radioactive dust, smoke, and soot, blocking 90% of the sunlight from reaching the surface. But between the immediate effect of the missiles themselves and the delayed effects of radiation poisoning, the vast majority of the earth's human population will be gone (and for those of you more worried about the precious polar bears, they'll be gone too).
My point is that, even if global warming is happening, even if we are causing it, and even if we can stop it, there is no proof that doing so will benefit us at all. In fact, one can easily make the case (as I have) that the benefits of global warming will outweigh the disadvantages. Moreover, the case can also easily be made that the sacrifices we will have to make to stop global warming are far, far worse than global warming itself. Are you willing to give up your freedom and comfort to stop global warming? Are you willing to sacrifice the world's economic prosperity, and even its food supply? Are you willing to precipitate a massive world war, probably ending in nuclear Armageddon? If so, then let's just launch the nukes now and get it over with. Because I, for one, don't want to live through the loss of freedom, comfort, prosperity, and food that will otherwise precede the Armageddon.
Are there benefits? The most noticeable pro of global warming is just that, warming. Increase in temperature will help to decrease some human pollution. This could be as little as reducing the need of wood to burn or using of heaters for the winter months. Also some areas will benefit from longer summers and then increasing agricultural growth seasons (Janzen 2007).
Another benefit to the idea of global warming is stimulation in the economy. Since most societies are based on consumer goods, people who will begin to "prepare" for the long heat swell that may affect say water supplies in some areas. Also several companies are now investing in research of the effects global warming will have on ecosystems.
