Good grief, I thought we were past this already. Science has already establish the earth is indeed heating up. Any idiot who's been alive for more than 10 years & who goes outside (no offense
/.) can plainly see the earth is heating up.
If you still doubt, try this simple exercise:
Step #1: Look at old pictures of glaciers from all over the world.
Step #2: Compare pictures of those places to current pictures of the same places from any point in the year.
----- OR -----
Step #1: Go outside.
Step #2: Hike in the high country for multiple years.
Step #3: Take pictures of the same areas of the high country each year, including glaciers in your photos (assuming you can find large glaciers in your neck of the woods).
We've had glaciers recede by MILES. We've had chunks of ice the size of Rhode Island break off the Antarctic and melt. What causes ice to melt? Hmmmmm, could it be.... heat? In long-standing ices case (e.g. glaciers, the Antarctic) could it be heat that wasn't there before? DUH! Figure it out for yourself people... it's not that hard.
The only debatable questions are:
1. What is causing the earth to heat up?
2. How fast is the earth heating up?
3. What will the ramifications be as the earth heats up?
4. What, if anything, can we do to counteract the trend?
5. Should we counteract the trend?
However, considering that deniers still exist (mainly due to vested interests), how highly politicized an issue this has become (again due to vested interests), how polarized most countries have become, and as a result of all of the above, how long it has taken to answer this most basic of questions... we are all hopelessly lost, at least until wars begin over fresh water, and the front page of every major newspaper hits deniers in the face with undeniable truth. Unfortunately, that's making the MAJOR assumption that people will put the pieces together, and that they won't be more worried about their bank accounts than drinking water.
