in figures how much has the earth warmed up because of global warming?

Question

in degrees celcius plz

Answer 1

Seems like a simple enough question but it's not all that easy to answer - it's not as simple as comparing the temps in the past with the temps now because there are many other factors which contribute to both the warming and the cooling of the planet and not all of these factors can be accurately measured.

Based on some long winded and boring calculations that I did a while back...

In the last 25 years by 0.39°C
In the last 50 years by 0.55°C
In the last 100 years by 0.82°C

The next IPCC report to be published has very similar figures for 50 and 100 years but their figure for 25 years will be a bit higher than mine - averaging 0.0177°C per year as opposed to 0.0156°C.

Answer 2

In Celsius as you asked.....in the past 100 years it was .8 of a degree. Over the Past 500 years (before cars, factories, and other "pollutants", 3.9 degrees. And with facts and trying to "GUESS" on the future, it depends on what facts you want to add to the equation....such as how many "Carbons" everyone is going to release, how many NATURAL DISASTERS such as VOLCANO'S and WILD FIRES there are, etc.....it is all a guess.
And also if you add in the past history of the world, and how the world has heated and cooled, every 1000 years, how much more will it heat before it cools, that has to go into the equation, (which most Green's don't want to look at or consider).
But look at it this way, with all cars, factories, and other pollutants, we have only added less then one degree, not to shabby for 100 years.
And in the year 3007, people will wonder why the earth is cooling so much and trying to find out how to heat up the planet.

Answer 3

I don't believe in global warming. I think it something that those hippi environmentalist made up. Just kidding. But I was in eastern PA this summer and it wasn't warm at all. I am kinda scratching my head wondering if it was a fluke or is global warming as big as a problem that the media is making it out to be.

Answer 4

About 0.8 degrees C from 1900 until today.
Not too bad.
But there is some danger that this warming trend may continue for the next 3000 to 5000 years, if there is positive feedback of natural greenhouse gasses.

Answer 5

Climate models referenced by the IPCC project that global surface temperatures are likely to increase by 1.1 to 6.4 °C (2.0 to 11.5 °F) between 1990 and 2100.[1] The range of values reflects the use of differing scenarios of future greenhouse gas emissions and results of models with differences in climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a millennium even if greenhouse gas levels are stabilized.[1] This reflects the large heat capacity of the oceans.

An increase in global temperatures is expected to cause other changes, including sea level rise, increased intensity of extreme weather events, and changes in the amount and pattern of precipitation possibly resulting in more frequent floods and drought. Other effects include changes in agricultural yields, glacier retreat, species extinctions and increases in the ranges of disease vectors.

Answer 6

Since the 1920s, the Earth has warmed about 1.8 C. It is expected to rise another 1.5-4.5 C by the end of the century. One (of a number) of negative consequences of this would be a rise in sea levels of up to 20 feet--sufficient to drown every seacoast city on Earth.

Answer 7

the earth warms and cools in cycles. right now we are in the warm cycle. wait about 10 years and we'll be in the cool cycle as far as the amount of degress it changes frequently in tenths of degrees. for example 60* and 60.1* it only change 1 tenth. very very minor and i'm not sure the exact celcius amount that u wanted i just know it fluctuates often.

Answer 8

The average global temperature has increased about 0.6°C in the past 40 years:

Answer 9

Well, it's raised about 2 degrees. That may not seems drastic, but in some ares, it's as big of a change as a whol continent shift.

Answer 10

you should watch An Inconvenient Truth. It'll give you all the statistics you need to know pertaining to global warming.
