is global warming just a phase of earth?

Question

my dad says that earth is just goin thro a phase of wich it gets hot then it will get coller soon.what do u think?

Answer 1

It is the destiny of the man who have been doing this for over a century.
To prevent/reduce the global warming, one of the option is to grow more and more and more trees, creating a forest like environment.

CAN U TAKE THE INITIATIVE TO PLANT 100 TREES IN YOUR AREA. THIS IS A CHALLENGE. GET THE HELP FROM ALL IN UR AREA. JUST DO IT. IF U CAN DO MORE THEN THERE IS NOTHING LIKE IT.
MAKE SURE THE TREES GROW. THE BIRDS WILL HAVE MORE HOMES. & U CAN SAVE A 1/4 OF A DEGREE OR LESS, BUT THE WARMING WILL SURELY REDUCE IF A MILLION OF PEOPLE WILL DO THE SAME

I HAVE BEEN DOING THIS.

Answer 2

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.

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.

Answer 3

The term "global warming" is a specific case of the more general term "climate change" (which can also refer to "global cooling," such as occurs during ice ages). In principle, "global warming" is neutral as to the causes, but in common usage, "global warming" generally implies a human influence.

An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados. Other consequences include higher or lower agricultural yields, glacial retreat, reduced summer stream flows, species extinctions and increases in the ranges of disease vectors. Warming is expected to affect the number and magnitude of these events; however, it is difficult to connect particular events to global warming. Although most studies focus on the period up to 2100, warming (and sea level rise due to thermal expansion) is expected to continue past then. However, the uncertainty is more significant regarding how much climate change should be expected in the future, and there is a hotly contested political and public debate over what, if anything, should be done to reduce or reverse future warming, and how to deal with the predicted consequences.

Answer 4

im gonna express how i feel on this. I believe its not just a phase. The world is different that it was in the past. In the past few centuries technology has catapaulted us to a new and different world. If warming did occur before, the world was in a much more natural state compared to today. I believe if the world doesnt snap into it and start fixing the problem we could be headed for a unsettling future.

Answer 5

The Earth has already gone through many periods of hot ( desert periods ) and cold ( ice ages ) and it will probably do so again. These cycles happen over long periods and there is not much humans can do to change things.

Answer 6

Yeah, it might be a phase, but I don't want to have to fry and then freeze! Your dad might benefit from seeing "The Inconvenient Truth" so he could see the facts presented. Do you think the many scientific studies are making this up? Why would they? It might be a phase, but it's because we are 'keeping a messy house' (so to speak) and we need to clean up.

Answer 7

I don't know, but surely some of the scientific scholars of Yahoo! Answers will have an idea.

Answer 8

many opinion no glitter. phase earth has to go through .normal response ?who can say ?

Answer 9

possibly or it may take hundreds of years to change back. who knows.

Answer 10

yes
