Global Warming Question?

Question

How much do you think the temperature will rise due to the apparent man induced global warming?

Answer 1

somewhere between 10 and 15 thousand years ago the temperature rose 7oC in 15 years and flooded a place called doggerland (landmass between england and europe). Noone in their right mind could blame that on Man. It happens, but nobody can know what will happen and when, you can't predict mother nature. The vikings sailed up to greenland in their time, because earth was so warm there was no ice in greenland. Yellowstone could errupt before global warming gets a grip.

Answer 2

The current temperature change attributable to man is 0.5C in the period 1980 to 2000. On this, the overall temperature alone would rise 1 degree every 40 years. Bear in mind there has also been an increase in the rate of warming over the last 5 years, so it is warming faster.

This is an average. Certain parts of the world, notably most of the US, have not experienced any change, or have had a drop in temperature (central and eastern Europe) of 0.1 degree - around about latitude 60 degrees North and 30 degrees south. Areas such as the south pole and Southern Africa have seen an increase of 0.9C and the north pole of 1.15C http://data.giss.nasa.gov/cgi-bin/gistemp/do_nmap.py?year_last=2007&month_last=03&sat=4&sst=0&type=trends&mean_gen=0112&year1=2000&year2=2005&base1=1951&base2=1980&radius=1200&pol=reg .
This is why scientists prefer to call it "global climate change" rather than "global warming".

Also, there are certain "collapse" events that may occur. For example, the ice shelves melting will dump freshwater into the Gulf current and may temporarily stall it thus lowering European temperatures. Conversely, as the ice melts, the polar land and sea exposed will absorb more solar radiation rather than reflecting it back into space. This will increase the temperature of the sea at the poles, accelerating the melting of ice.

This graph shows the increase in CO2 since 1960 http://en.wikipedia.org/wiki/Image:CO2-Mauna-Loa.png

This for all the major greenhouse gases http://en.wikipedia.org/wiki/Image:Major_greenhouse_gas_trends.png

This compares the solar radiation (misleadingly claimed in the swindle of the "Great Global Warming Swindle" programme to be the cause of warming - http://en.wikipedia.org/wiki/The_Great_Global_Warming_Swindle ) with CO2, methane and temperature http://en.wikipedia.org/wiki/Image:Vostok_420ky_4curves_insolation.jpg
(notice particularly around 150,000 years ago the correlation of CO2 to temperature is a far greater fit than that of temp to solar...)

Make your own mind up, but I would rather be cautious than suffer any of the potential risks. There is already talk of another drought order in London again this year, for example and that is just a minor inconvenience (for me, anyway, as I no longer run a car that would need washing, have bought two water butts for the garden, and have a hose to run from the bath to the trees ... and a house on a hill way above sea level).

Answer 3

Even the best mathematical model will fail to predict it.It may be anything betwwn 2 -6 degree C.But global heating up is not by man alone.So many unknown factors are there.Barton told that world will suffer a "Heat death".This is based on theory of entropy.

Answer 4

Who says that this is "apparent" ??
The Earth's temperature fluctuates all the time. The mean temperature of the Earth has increased about one degree in the last 100 years....

Answer 5

Impossible to say but models estimate it will be between 2 and 6 deg centigrade by 2100.

2 degress will not be too devastating but 3 degrees and upwards will be very significant.

Answer 6

global warming... okay have you reviewed the warming & cooling trends for the earth? How far back did your study go?

Answer 7

Average temperature in the temperates: 20*C.

Temperature when temperature rises: 40*C

Answer 8

If you listen to the experts, then we are doomed before too long, they say a further 6deg will tip us over the edge. If you take into account that America, China and India are not willing to change their carbon footprint, then we are all in big trouble.

Answer 9

Too much.
I am not sure of what the scientists say exactly the number is, but I believe them.
We need to make a change NOW.

Answer 10

the way people go on about it i think it must be about a trillion degrees
