You are not helpless in the fight against global warming. Here are five things you can buy that will help solve the climate crisis…and save you a few bucks!
Compact fluorescent light bulbs: These energy-efficient bulbs cost less than $4 and are produced by major corporations like GE. If every household in America switched five regular light bulbs for five fluorescent bulbs, it would be the equivalent of taking 1 million cars off the highways for a full year.
Outdoor solar lighting: These yard or patio lights cost less than $20, and they don't burn any electricity or produce any CO2.
Programmable thermostats: Though these thermostats cost from $50 to $100, they can actually cut your heating and cooling costs. Set the setting so it's a little bit cooler in the winter and warmer in the summer when you're not in the house. A difference of 2 degrees can reduce a home's CO2 emissions by up to 9 percent over the course of a year.
Air filters: Changing the air filters in your heating and cooling systems regularly can knock 2 percent off of your CO2 output each year.
Electric hot water heater blanket: Hot water heaters use a lot of energy and generate a lot of CO2. A blanket costs less than $18 and can cut your home's CO2 emissions by almost 4-1/2 percent.
Also, when you're shopping for major home appliances, look for the Energy Star label.

first of all.... they have their own causes for global warming. Apparently, the cause for Earth is too much CO2. It is caused be hummers, SUV's and Appliances. And, to tell you, the AC, although it makes the atmosphere cool inside, it warms up the temperature in the air surrounding it. Have you thought about Venus and Mar's atmosphere since the beginning of the universe? It is supposed to be inhabitable. The heat is definitely higher than Earth's which makes make Earth habitable by humans. What a stupid question.

Man made Global warming is more hype than Science.
Here is why:
Earth's 4.5 billion year history is one long story of climate change. This fact is pretty much accepted by those who think global warming is a natural process, and those who think it's caused by man.
In more recent history there has been: a mini ice age in the seventeenth century when the Thames froze so solidly that fairs could regularly be held on the ice; a Medieval Warm Period, even balmier than today; and sunnier still was the so-called Holocene Maximum, which was the warmest period in the last 10,000 years.
Those who think global warming is a natural process point to the fact that in the last 10,000 years, the warmest periods have happened well before humans started to produce large amounts of carbon dioxide.
A detailed look at recent climate change reveals that the temperature rose prior to 1940 but unexpectedly dropped in the post-war economic boom, when carbon dioxide emissions rose dramatically.
There is some evidence to suggest that the rise in carbon dioxide lags behind the temperature rise by 800 years and therefore can't be the cause of it.
In the greenhouse model of global warming, heat from the sun's rays is trapped by greenhouse gases in the atmosphere. If it weren't for these gases, Earth would be too cold for life.
Greenhouse gases trap heat from the sun within the earth's atmosphere. This is the greenhouse effect. Traditional models predict that increasing concentrations of greenhouse gases lead to runaway heating.
If greenhouse warming were happening, then scientists predict that the troposphere (the layer of the earth's atmosphere roughly 10-15km above us) should heat up faster than the surface of the planet, but data collected from satellites and weather balloons doesn't seem to support this.
Those who think global warming is a natural process say that the troposphere is not heating up because man-made greenhouse gases are not causing the planet to heat up.
For some people, the final nail in the coffin of human-produced greenhouse gas theories is the fact that carbon dioxide is produced in far larger quantities by many natural means: human emissions are miniscule in comparison. Volcanic emissions and carbon dioxide from animals, bacteria, decaying vegetation and the ocean outweigh our own production several times over.
Others would argue that carbon dioxide isn't the only greenhouse gas and that human emissions could tip up a finely balanced system.
New evidence shows that that as the radiation coming from the sun varies (and sun-spot activity is one way of monitoring this) the earth seems to heat up or cool down. Solar activity very precisely matches the plot of temperature change over the last 100 years. It correlates well with the anomalous post-war temperature dip, when global carbon dioxide levels were rising.
In fact, what is known of solar activity over the last several hundred years correlates very well with temperature. This is what some scientists are beginning to believe causes climate change. Others feel that solar activity only explains the fine details of temperature change.
So how does the sun affect the earth's temperature? The process scientists suggest is that as earth moves through space, the atmosphere is constantly bombarded by ever-present cosmic rays. As these particles hit water vapour evaporating from the oceans, clouds form in the atmosphere. Clouds shield Earth from some of the sun's radiation and have a cooling effect
When solar activity is high, there is an increase in solar wind and this has the effect of reducing the amount of cosmic radiation which reaches Earth.

I can, there's no SUV's on Mars, so that's not causing the warming there.
The problem with the theory is we don't know the warming and cooling trends of Mars, Venus or any other planets. On Earth we have in places hundreds of years of human records, also we can do testing on different things on Earth to get a view of how things used to be(for example through the study of ice cores). So here we can have a CO2 record for hundreds of thousands of years, pre-Jesus as it were. So we can compare those figures with current trends, and see where we are and where we are going. On Mars or Venus we have only had the ability to measure their temperature for less than 100 years, I doubt even 50 years ago if we could do it, we just don't have the records.
The pollution(CO2) on Earth does cause a big problem here, it's higher now than it has been in something like 80 000 years. The temperatures rise as the CO2 rises, it's a constant measurable effect. We have no way of measuring the history of any gasses, or any other activity on other planets to say the same about them either way.
But, back to your concept, even if it is somehow natural, it's still happening, and if the temperature records that we can see from ice cores or tree growth tell us it's hotter than it has been in thousands of years, then we have no way of predicting when it will stop. This is a worse scenario because it means we cannot do anything significant about it because we cannot predict where it will go or if it will end, and we cannot change it if we do not understand it. This can mean that we are going to get hotter and hotter, the climate will get worse and worse, and if the rate is constant and unstoppable then it means catastrophic failure of life on the planet.
The cause is debatable and should be debated openly, to come to the best SCIENTIFIC conclusion. Then the best action should be taken to stabilize the planet, because we can, and we should to ensure our survival, because we have no way of escaping this vehicle as it were. Idle speculation or "belief" should be taken out of the equation for pure facts, instead of conjecture.
I personally am happy that there is no longer any Climate Change denies, people no longer say it isn't happening, but rather are debating the cause, which is necessary, so we can do something about it.
We cannot simply throw in the towel as our way of life is changing against our will. If nothing else we should take action in order to have a good healthy economy, which ensures you can afford your SUV, instead of having to worry about payment to fix any number of issues that come up from Climate Change(floods, worse storms, etc).
It's for the best that we find the best action to take and take it.

Try asking in the Science section. A debate on global warming has very little to do with the politics of running a country. Tell Al Gore to leave the scientists alone and let them finish their studies.

Human life existed on those planets long before it did on Earth. They both (Venus and Mars) suffered great devastating catastrophies. This casued an evacuation to Earth of their high ranking officials, which started civilization as we know it here. A carving later discovered in a deep cave, somehwere in a lost Mayan city, revealed what appeared to be an astronaut driving around in a big SUV with pollutants streaming from the rear end, and people in great numbers behind it either dead or dying. This is true, I swear. Cheers!

The reason that they cannot answer it is because they do not want to say that the one common factor is the sun. That the sun is causing global warming. It has happened before and will happen again, we are along for the ride, we did not cause it and we cannot stop it. Al Gore has set up a corporation to sell carbon credits, he is making money on this scam.

I am by no means a Gore supporter, but Venus and Mars have entirely different atmospheric compositions than Earth.
Mars and Venus are also lethal to humans.

Yah, the stupid liberal democrats fail to realize that the sun holds a bigger stake in the climate of our planet and that carbon dioxide is only a small part of the equation when it comes to affecting the climate. They fail to see that most of Antartica is actually getting cooler. Meanwhile their precious Al Gore is flying around in a private jet while the fools that follow him are trying to lower their carbon footprint.
Lets not forget their supposed answers to this whole global warming thing. Limit industry with strict pollution standards, basically try to destroy the oil industry, and oh yes use energy efficient mercury light bulbs.

True Global Warming believers are not interested in facts. To them man made global warming is written in stone. The fact that not just Mars but othet planets are warming up is unimportant They may or may not be warming, but on Earth it is caused by people, specifically people in the USA.
