Do you believe we are experiencing global warming/climate change? (agriculture, food)

How much longer does your uncle think we have left?

It has happened before, for sure.

I also think that we humans are contributing factors as well, how could we not be having a neg effect on the environment.

Yep.

I find it amazing so many people just jump to the conclusion that global warming is caused by humans. You'd be amazed how many scientists don't think that it's 100% human caused. The few that do claim it though are the ones that get the media attention and instill this panic.

The answer is that we never have before. Global warming and global cooling are both caused by the sun. Always have been. There is evidence that a forest fire burned Siberia once. That's a huge area. That natural event must have darkened the sun over North America for a while. In the 1800s we had a "year without a summer". People starved and there were many crop failures. It was caused by the eruption of Krakatoa in Indonesia. More recently, the eruption of Pinatubo in the Philippines spewed more pollutants into the air in one natural event than all the coal mined since the industrial revolution. It did make for a summer of beautiful sunsets though.

very good post

just 30 yrs ago, the same or similar folks were screaming we were heading for an ice age.
we cant predict the local weather with accuracy..within a few days...yet the experts can predict global weather trends?


northern is correct,,about the sun

greenland is called greenland for a reason,,,

They weren't just being sarcastic with their sophisticated viking sense of humor?

I was told that when Greenland and Iceland were settled that they knew the name's would eventually be told to their enemies, so they devised one name [Greenland] that when their enemies heard such a name, they would be drawn toward it, insisting that it held great harvests and prosperity, and thus be drawn toward their own demise.

Likewise 'Iceland' is named with the hope that anyone who ever heard of such a place would from thence forth steer a wide berth around and avoid such an awful place.

Great ploy on the part of the settlers!

I do understand that underneath Greenland there does lay the remains of an ancient forest, however that forest was covered by ice thousands of years ago, long before the first human settlers. Perhaps during one of the earth's previous inhabitants maybe they had made use of the 'greenness.

Either way, even if mankind is not to blame...is it really such a bad idea for us to stop polluting our planet so much? Is it really such a bad idea to make discovering cleaner/greener technologies a priority? It seems like these are things we should be focusing on regardless of who's to blame for global warming.

This is exactly how I feel, and frankly the debate can go on forever laying blame in many laps. The fact of the matter is though, is it really all that difficult to be progressive concerning our natural resources and alternatives?

A few months at most...so no point in making any more contributions to that 401K.
