Can planting a tree stop the sea level from rising, the ice caps from melting and hurricanes from intensifying?
A new study says that it depends on where the trees are planted. It cautions that new forests in mid- to high-latitude locations could actually create a net warming. It also confirms the notion that planting more trees in tropical rainforests could help slow global warming worldwide.
According to the latest United Nations scientific report, leading scientists around the world agree that man-made greenhouse gases from fossil fuels are causing global warming. Effects are already being seen worldwide. And long-term consequences are devastating, pointing to a darker future each day we fail to act.
Solutions
Many possible solutions have been proposed to stave off global warming, should it actually be occurring. Some are very practical, while others are grandiose, to say the least. What is certain is that as the world’s population continues to grow and developing nations develop, the world’s need for space and energy will continue to grow. The need for space will accelerate deforestation. The need for energy will almost certainly increase the rate of fossil fuel burning. Listed below are a number of proposed “solutions” to combat global warming.
What is global warming? This is a fair question, as much written and said about “global warming”. The term is often misused and people tend ask questions like, ‘do you believe in global warming?’ This is a bit like someone asking an economist, whether they believe in inflation. It is difficult to know where to start when answering, What is Global Warming? This is because there are other hidden questions buried in the original one. Many people when asking the first question, are often also wanting to know if the warming is attributed to human activity ( anthropogenic); are greenhouse gases building up in the atmosphere?; and is the warming something they should be concerned about? The short answer to all those questions is YES!
Scientists use “global warming” in a precise way, to mean “a tendency for the globe to warm over a given period”. There is a great deal of scientific study focused on climate change, and the majority of scientists agree that the average global temperature is increasing.

When
Have you ever read anything good about global warming? Why is all the news always bad?
Objectively speaking, any environmental change should have both positive benefits and negative effects. For example, theory predicts and observations confirm that human-induced warming takes place primarily in winter, lengthening the growing season. Satellite measurements now show that the planet is greener than it was before it warmed. There are literally thousands of experiments reported in the scientific literature demonstrating that higher atmospheric carbon dioxide concentrations — cause by human activity — dramatically increase food production. So why do we only hear one side about global warming?
The Global Warming Solutions Act of 2006, a law in California, was signed by Governor of California Arnold Schwarzenegger on September 27, 2006. It sets up the first enforceable state-wide program in the U.S. to cap all greenhouse gas emissions from major industries that includes penalties for non-compliance. In signing the bill into law, Schwarzenegger declared, “We simply must do everything we can in our power to slow down global warming before it is too late… The science is clear. The global warming debate is over.”
Global warming is caused by an increase in the greenhouse effect. The greenhouse effect is not a bad thing by itself — it’s what allows Earth to stay warm enough for life to survive.Although it’s not a perfect analogy, you can think of the Earth sort of like your car sitting out in a parking lot on a sunny day. You’ve probably noticed that your car is always much hotter inside than the outside temperature if it’s been sitting there for a while. The sun’s rays enter through your car’s windows. Some of the heat from the sun is absorbed by the seats, the dashboard and the carpeting and floor mats. When those objects release this heat, it doesn’t all get out through the windows. Some is reflected back in. The heat radiated by the seats is a different wavelength than the light of the sun that made it through the windows in the first place. So a certain amount of energy is going in, and less energy is going out. The result is a gradual increase in the temperature inside your car.

Some gases (”greenhouse gases”) let sunlight in, which warms the Earth, and then block that heat from leaving. That’s the “greenhouse effect”, and it’s a natural thing, mostly caused by water vapor.
Man is making excessive amounts of greenhouse gases, mostly by burning fossil fuels. That causes the delicate natural balance to go out of whack and the Earth warms. That’s global warming.
After years of debate, consensus among most of the world’s scientists holds that we are warming the planet. Unless we take steps now to curb global warming, our way of life, our planet, and our children are all in grave danger. There is hope. Each us can make simple decisions
Effects of globalwarming
The net impact of globalwarming so far has been modest, but near-future effects are likely to become significantly negative, with large-scale extreme impacts possible by the end of the century.
The predicted effects for the environment and for human life are numerous and varied. The main effect is an increasing global average temperature. From this flow a variety of resulting effects, namely, rising sea levels, altered patterns of agriculture, increased extreme weather events, and the expansion of the range of tropical diseases. In some cases, the effects may already be occurring, although it is generally difficult to attribute specific natural phenomena to long-term globalwarming.
