global warming? is it happening and what are the consequences?

Answer 1

Every day. And that's what keeps the Earth at a liveable temperature. Now if you're worried about the run-away global warming effect (where the Earth keeps getting hotter), conventional science suggests that yes - it is happening. How do we know? Because the temperature of the Earth isn't supposed to change this rapidly. It should take a few thousand years, and it's taken only a few hundred. What are the consequences? If the Earth's temperature doesn't cycle down like the last time - well, just look at Venus. She is why all scientists freak out about global warming, because we don't want to be like her. How long will it take? No one knows for sure.

Answer 2

It is happening. In the next 15 years, the Ice caps will melt and the seas will rise. This will mean that small islands will disappear completely just like with the tsunami. There will be a whole bunch of tsunamis.

As the sea rises, the new water will evaporate faster and cause more clouds to form. After 20 years the thickening of the clouds around the earth will block off the heat from the sun.

So the earth will go from extreme heat to cold. The whole planet earth could be wiped out by 2022.

If you look at all the barren planets in outer space, the same thing happened to them milillons and millions of years ago. That is why there is no life on those planets. The same thing will happen to the earth soon as well.

The scientists and the big wigs in government will not tell you this of course. Why? Well, there would be panic if they told the truth. People would revolt. Suppose you had a loan that was due for repaying by 2023, would you bother to pay it back when you know that the earth is doomed?

A lot of the hot shots here will bring up a load of boring articles and tell you it is the truth. They dont understand, they are just saying what they have been told.

There is nothing that we are able to do about global warming. In the end we are doomed. We really are.

Answer 3

Global warming is 100% real, almost entirely the fault of human activity, and it is a big problem.

CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.

Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest, and 2006 is shaping up to maybe break that record.
(see links below)

How's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.

There has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.

Yes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up.

Just to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.

Global warming will cause more frequent and larger storms, higher sea level, flooding populated places, and massive climatic and ecological issues.

Answer 4

Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades. The increased amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) are the primary causes of the human-induced component of warming. They are released by the burning of fossil fuels, land clearing and agriculture, etc. and lead to an increase in the greenhouse effect.The predicted effects of global warming are many and various, both for the environment and for human life. These effects include sea level rise, impacts on agriculture, reductions in the ozone layer, increased intensity and frequency of extreme weather events, and the spread of disease. In some cases, the effects may already be being experienced, although it is difficult to attribute specific natural phenomena to long-term global warming. In particular, the relationship between global warming and hurricanes is still being debated.

Answer 5

yeah, its happening, and the consequences are wonderful. first of all, there is an upper limit on global temp, as the more icecaps that melt, the more liquid water we have, the more evaporation we get, the more cloud cover and rain we get, cooling off the globe, its a self adjusting radiator. the effects of global warming will be fewer droughts, explained above, fewer hurricanes, as they are caused by hot water. melting icecaps cool down the oceans, AND they make them a little deeper, which also cools them down. deep water is cool water. longer growing seasons, expanded growing areas. so cheaper food, and less starvation.increased warmth also increases winds. so windmill power generation will actually work. anyone who thinks people are the cause of this are self important, childish little fools. we don't have the power to change the climate.

Answer 6

OK if co2 is 30 % higher where is it ,I have used some of the most advanced gear that would measure 1 part per million and even working with co2 the highest measurement was 2 parts per million. where is the rest of the co2 hint the green plants love it. The same with Methane measure it , it is not there.
the data is false so therefore global warming is false.

Answer 7

Unknown. It is believed to be happening though there is no definite proof. There are many variables to life. Any change in the balance has an effect. Sometimes adaptation occurs, sometimes death. The amount of oxygen in the air has changed as evidenced by ice and fossil records. Insects cannot get as big as they used to. We will have to take much more data over a long term to know with anything resembling certainty. BUT, it does appear to be happening.
