Global Warming. What is the "correct" average temperature for the earth?

Question

Also what is the acceptable delta? In other words how much can it change and it not be man made global warming?

Please be specific and avoid answers like "u suk, glubal worming is reel".

Give me a call and we will see what we can do with your extra heat.

If you don't know the correct how do you know it is going to high or low?

you are right about highest in 650,000 years but not the HIGHEST. You will notice we had ice ages when CO2 was higher than today.

Answer 1

15 Celsius and it's called climate change.. You'll have to be specific if you want a specific answer. Your question is Illogical, The earth has cycles of warming and cooling, that is not debated .. what is different now as opposed to the last 4 cycles of Ice age.. 650k roughly is that Carbon Levels are 300% higher than they have ever been before, the only factor that has changed in that time period is the industrial revolution, which is also backed up by this same data that shows the spike has occurred in the last 100 years... is that exact enough? Lastly there is no average above or below 15Celsius that can be considered acceptable...

Answer 2

According the the June issue of Environment & Climate News, Vol 9 No 5, the current rate of global warming is "a remarkably constant and non-alarming rate of 0.17 degrees C per decade" (Page 10) That means that at this rate it would take over 50 years for the temperature to rise by one degree.

Answer 3

There is no "average temperature" for the earth, as weather patterns are not static, and fluctuate wildly over time. Many factors influence the temperature and weather patterns of the Earth, including Sun spots. During times of high sun spot activity, the temperature of the Earth increases. This is occurring right now, and proof positive is that the temperature on Mars has also increased. Al Gore has yet to explain how Americans are causing Martian global warming or how he can personally profit from it.

Answer 4

this is the question i ask everyone who believes global warming is happening and we are responsible for it. Nobody knows what the correct temperature of the earth is supposed to be. Everyone bases all of their information off the present time frame of the past several hundred or so years. But who is to say we are living on earth when it is too cold?? Look at how many ages we have had in the history of the earth. Change is constant, nothing stays the same. So i just don't understand why everyone is up in arms about global warming.. oh yeah, IT IS A POLITICAL ISSUE!!!!

Answer 5

Getting an average temperature of every point on earth is like averaging every number in the phone book, it is meaningless and thus the delta is meaningless. If you are trying to determine global warming, you need a much more sophisticated statistical analysis, and there is a dispute as to how to do that.

Answer 6

About 56-57 degrees Fahrenheit (13-14 degrees Celsius) with a variance of +/- 3 degrees F.

Answer 7

Take it as 14 C.

During the past century, global surface temperatures have increased at a rate near 0.06°C/decade but this trend has increased to a rate approximately 0.18°C/decade during the past 25 to 30 years.

Answer 8

If you are actually really interested, the US government’s EPA website explains the basic concepts of measuring how rising atmospheric concentrations of greenhouse gases are contributing to rising global temperatures. The temperature information for the past few years is placed in historical context.

Answer 9

There is an undeniable correlation between CO2 levels and temperature, and, that CO2 levels exceed anything the earth has experienced in 650,000 years, the only question is, will these remarkable increases in CO2 lead to catastrophic temperature increases.

Answer 10

I do not know average, but probably 5 degree centigrade increase will make it unlivable.
