There are things individuals can do to help stop global warming. Yet, when nations get involved, it is to everyone’s benefit to see to it that the right steps are taken. Nations can combat global warming by many different means.

For one thing, a good forestry department can have a huge impact. The carbon dioxide that is one cause of global warming is eaten up by trees. If a country fosters the growth of its forests and does not allow them to be cut down indiscriminately, global warming will be slowed down.

Another thing nations can do is to focus on energy efficiency. The less energy is used, the less global warming has a chance to take hold. A country can place efficiency standards on appliances and cars. Even better, they can redesign cities so that walking and cycling can become an option instead of people having to drive everywhere.

Alternative sources of energy emit little or no greenhouse gases. Using them will help curb global warming. Hydro-power, solar energy, and windmills can be used to take the place of burning gas, or coal for electricity. Windmills, in fact, are already being set up by the scores in many fields in out-of-the-way places. This is a good step to prevent global warming.

Nations can also be quick to adjust their policies to the climatic changes of the times. When one type of crop will no longer grow well because it needs a cooler climate, that crop can be replaced in that area with a different kind that will. Nations can build aqueducts to transport water to drought-ridden areas.

There are different ways that nations can get their message about global warming across. First, they can make laws about it. They can require people to use environmentally-friendly appliances, fuel sources, and vehicles. They can make it a legal requirement for auto makers to reduce harmful emissions given off by their cars.

Another way to change people’s behavior is to make it financially advantageous to be concerned about global warming. If gas prices are higher, people are spurred on to finding a more fuel-efficient vehicle, or even a different fuel source altogether.

Tax incentives and government subsidies can also encourage people to think about global warming. The only problem is that this approach usually favors those who have more money in the first place.

Governments can make it their business to inform and educate the people of the country. With news and data about global warming, people will be prompted to take it seriously. When methods for reducing greenhouse gases are made known by the government, people have a chance to put those methods into practice.

Finally, it is essential that governments get involved with making sure that research and development are done. Global warming cannot be overcome without good information. It is to the advantage of every citizen when the nation puts some of its focus on global warming. When a country approaches global warming with a common sense, proactive sensibility, beneficial changes can be made.

When you think of global warming, you might envision dramatic scenes like hurricanes and melting glaciers. The truth is that something as commonplace as agriculture is already showing signs of the effects of global warming.

Some studies show that the news of global warming is not all bad for farming, at least not in the short run. While humans have changed many environmental factors by their activities, the short term effects of these changes often lead to better crops.

Because of global warming, temperatures obviously increase. This has some temporary benefits. For awhile, it will simply mean more time for crops to mature because of a longer growing season. This is especially true of regions where the spring and fall were once quite cool.

On the other hand, these higher temperatures can bring problems in other areas. In regions that are already warm, global warming will cause the plants to languish in the heat. Soil evaporation rates will be very high, leaving very dry earth. Add to that, droughts that will make both the soil and the air dry and might even lead to burning of some crops.

Global warming is sure to bring about changes in precipitation. This will lead to changes in the soil moisture. Especially with the severe weather predicted with global warming, rain will come down hard when it does come. This will lead to more than usual soil erosion. These factors greatly affect agriculture.

Strangely enough, all the extra carbon dioxide in the air that brings about global warming also has a fertilizing affect on crops. This type of fertilization is most helpful for crops such as wheat, soybeans, and rice. CO2 fertilization is a beneficial by-product to global warming.

However, this benefit may all be in vain. When global warming pushes ground level ozone to higher stages, the carbon dioxide fertilization is voided out by tropospheric ozone. These ozone levels are influenced by both emissions and temperature. The result is that when the climate changes, the ground ozone levels will rise as well.

There have always been many obstacles to farming. Global warming just makes them more intense. Now, it is even more likely that a farmer will face droughts, floods, heat waves, and hurricanes, to name a few. They will be harder to overcome than ever before and they will certainly be less rare.

The overall predictions for the US are neither all bad nor all good. Crops are expected to benefit from the effects of global warming in many regions for awhile. In some areas, though, crops will suffer because of regional variations.

The Great Plains are now more susceptible to drought, thanks to global warming. However, Canada will probably benefit from the added heat as farming will take a Northward shift.

Right now, and in the near future, global warming does not seem to be a very dangerous situation for North American farmers. There might even be some positive effects. However, in the long run, nothing will be able to mitigate the damage that will be caused by global warming if it is not stopped.

The day may not be far off when the use of solar energy becomes a norm. There is now a deep conviction among experts that given a few years time, solar power will be in high demand that the cost will go down, inexpensive enough to undercut the prices of oil-generated electricity.

Previous predictions that it will still happen in a decade may no longer be true. The anger generated by the recent prices in oil and its vulnerability to market forces and other events may have already been enough to polarized people, governments and scientific communities into seriously considering a reliable alternative energy source.

You can not get a source more reliable than the sun. Even today homes that uses its power does not only benefit from the silent, energy generating, inexhaustible power of the sun, it also spikes up the prices of their homes. Those that have solar powered homes are even reimbursed for the surplus power that they supply to the power grid.

Presently, heliostats, photovoltaic cells and plate collectors are being used to collect the energy by focusing these panels towards the sun or constructing and installing the panels on spots where the sun shines most. Development in technology as we all know often has a snowball effect. It never stops rediscovering and reinventing that the speed of development could often be surprisingly fast.

Today, a polymer foil, thin as a sheet of paper and lighter by 200 times when compared to the regular glass collecting plates, are being developed. Chances are, these new inventions and discoveries could very well have a great potential for mass production. Previously, the glass-based materials used for heat collection need expensive substrates and require additional support for mounting due to its weight. The polymer foil, being very light could now be attached even to the walls of a structure.

So confident are scientists in the development of this technology that while the polymer foil is being developed, a plastic solar cell, based on nano technology is gaining breakthroughs. This plastic material can collect the power of the sun even on a cloudy day through harnessing the infrared rays is believed to be five times more efficient than the current technology.

While plastic materials for harnessing the power of the sun are not new, it is only recently that this plastic composite could harvest the infrared portion. Previously, only the visible rays are generated, the infrared part, which is half of the power of the sun, is invisible.

Currently, the best plastic solar cells could only harness 6% of the suns energy, with further study and development, this new plastic solar cells are expected to harness 30% of the suns solar power.

Scientists and researchers alike agree that ultimately, solar farms will be harnessing all our energy requirements and costs of power will drop. Today the price of solar powered energy is about 3 to 4 times per kilowatt hour compared with conventional electricity. That could change dramatically though the development of the existing technology and recent discoveries.

The roller pressed flexible plastic materials and the polymer foil are only two of the best hopes in arriving at a cleaner, greener and safer environment that could ultimately free the planet from its dependency on the depleting supply of oil.

The planet was once protected with ancient forests; it has been a shelter to almost 50% of all the animals and plants confined in lands. Also, the worldwide population depends on them for survival. The most diverse ecological units exist in these forests, and they serve essential help to our planet especially in matters regulating the climate. This is the very reason why deforestation and climate changes go hand in hand. Where deforestation is, climate alteration always follows.

Unfortunately, the forests that should be the world’s shield to the growing global warming are now under threat; almost 80% of the vast land areas all over the earth have been wiped out. Everything went by in a matter of 30 years, and the foundation is due to human doings such as destructive logging and agricultural land transformations. The fact that deforestation is the second cause to climate change should alert every human being in order to put to a stop to anything that may interrupt our normal ecosystem. If no moves would be done, further retaliation of nature would surely come to pass.

Major Carbon Storehouses

It is increasingly clear that our ancient forests play a crucial role in the regulation of world climate through carbon storage and water recycle back into the atmosphere. It is a fact that the green areas of the earth are regulators of climate, and destruction of that area means contributing to a climate change. Eighteen percent of all carbon emissions come from deforestation. Instead of the forest protecting us from disastrous effects, man made phenomenon make them our source of devastation instead.

Full grown forests are the greatest keepers of carbon dioxide. Other “keepers” include: the earth soil, the plant life, and the smallest and biggest trees. Some popular forests such that of Congo represent one of the planet’s enormous carbon sources on land, and destruction of it may cause more greenhouse gas to get trapped in the atmosphere.

The carbon is emitted from the green life through logging, burning and rotting. If these illegal activities happen frequently and continuously in all parts of the world, then the levels of carbon trapped in our environment is exceedingly augmented. Climate changes happen abruptly and changes in the world environment would slowly take place.

Deforestation and Its Effect On Climate Change

When deforestation is made, climate changes begin to progress over a period of time. The gradual modification in climate show insignificant numbers, but it affects the earth in great ways. The following are some examples of global changes after massive deforestation: temperature of global surface has increased to 1F, precipitation events happen around the world and in extreme cases, snow capped mountains have decreased in cover, sea levels have risen, and thawing of permafrost has slowly been happening over the years.

It is said that in a matter of 50 decades, the world may be in an irreversible state already. If things could be prevented now, then it is highly suggested that every human take part in preserving the world.

Controlling Climate Changes

If deforestation and climate changes go together, then unbinding them would be the first step to problem solving. Deforestation and other causes of climate alteration should initially be stopped so that further effects cannot take place. However, the only key to ending deforestation is through mankind.

If no human effort is exerted, then all else will be impossible to do.
