Glaciers melting...

A lot of different points of view. Not saying that oil is the sole source of co2 in the system and as mentioned a volcano can duplicate in a few moments what we have taken two centuries to accomplish (unverified, just generalizing). But there's a three pronged response to that, and two are linked.

First, we can't have any influence on geological impacts, nor solar load. In fact about five billion years ago our planet and sol started working out that relationship without our consent or advice.

Second, we are responsible for releasing back into the system the single largest cache of sequestered gasses in a willfull act. Should we stop? Slow down? No. Maybe. Yes. I don't know but it ties into the third point of my trident.

Third, we have got to stop destroying our forests, reefs, marshes, and even our deserts. Those are the tools our big buddy earth uses to "export nutrients" from the system.

I liked the remark about pavement and the heating and retention of that load. I consider it slightly ironic and so I will leave it with this. Ever wonder why the southern hemisphere doesn't suffer the same weather patterns/temperament as the northern hemisphere?

TO EXPAND ON WHAT I TYPED YESTERDAY.....

15 terawatts OR 1.504×1013 W OR 15,040,000,000,000 WATTS PER YEAR ARE USED BY HUMANS THAT EQUATES TO 41177275838.46 OR 4.11 X108 WATTS used BY HUMANS PER DAY

176 PETAWATTS 0R 1.760×1017 OR 176,000,000,000,000,000 W PER DAY HIT THE EARTHS ATMOSPHERE FROM THE SUN
SO HUMANS use ABOUT 2.33/10,000,000 OR 2.33 TEN MILLIONTHS OR 2.33 x10-7 OR 0.000000233% OF WHAT HITS THE EARTH EVERY DAY FROM THE SUN

sorry its in caps. i typed it up at work and e-mailed it to my home so i could cut and paste it.

i researched total energy consumption of humans per year and that data is from 2008.
i researched total solar constant per day and that empirical data is well excepted among scholars and the like.

On Live science.com it says A new study of glaciers in a portion of the Antarctic finds 84 percent of them have retreated over the past 50 years in response to a warmer climate.

I think it is the greeenhouse gases because as we drive in our cars we are releasing gases that are harmful to the environment.

I think them melting is just something that is naturally happening without the help of humans or global warming. it might be warm enought there to melt the ice but in some places they are breaking records for how cold it is.

i like this one.
from a personal opinion i think humans have a great affect on weather changes.
the earth changing naturally.
and humans are simply adding to it.
so things are changing much quicker.
