The whole point is that human activity is ACCELERATING the rate of temperature increase above the NATURAL short term warming that began about 150 years ago. cycles.
So if the earth heated by 1 degree in 150 years, then how much was it supposed to heat up if it weren't for us greedy humans that want to enjoy better life, with cars, trains, and fuel for our homes? So maybe the earth should have only heated up .5 degrees and now it heated 1 degree in 150 years? We are in a relativly "warm" period historically speaking, but we should feel guilty because we contributed as much as 1 degree to the overall temperature in 150 years?
The problem is, that if our activities cause too much variation in the natural cycle, we COULD have significant and profiund changes to weather patterns.
Key word is COULD... If we don't use fossil fuels we will certainly have more difficult lives. I am sure we can figure out a way to NOT use fossil fuels, but at this point in time they are the most cost effective. Thats why we use them!
Regarding "how Canada melted", that was part of the warming trend the earth has been in for the last 20,000 years or so, since the last glaciation (a relatively short term cooling trend, as opposed to longer term cooling trends lasting tens of millions of years, as opposed to short term temp cycles between glaciations, like we have been in the last several thousand years).
HOLD ON A SECOND. Now I thought you just said the earth has been heating for the past 150 years ( due to man)... but now your saying that we are in a " warming trend", and have been for 20,000 years?
Call me crazy, but 20,000 years of warming sounds like a long time. Sounds like mother earth has been heating herself up for a long long time. 150 years looks like a drop in the bucket compared to 20,000 years. Do you know where MAN, was 20,000 years ago?
Actually, we are in a period of relatively warm temps, it is usually cooler on the earth, we can expect anouther glaciation if history is a guide, but not for thousands of years.
You see that is funny. You say that based on history, cooler temperatures are on their way, yet you complain about global warming. I guess your predictions are those of the scientists you quote, or they are just based on "historical trends". So would you say the scientists have a "consensus" that cooler temperatures are on their way"?
Various theories exist to explain this.
So you mean nobody really knows for SURE what is going on? The earth could get hotter in the future ( like the previous 20,000 years), and the earth can cooler ( like even earlier). If the earth heats and cools itself ( and has been doing this forever), then why are you so worried about 1 degree in 150 years? Does that really seem like THAT much of a climate change in the grand scheme of things? Maybe they need more funding for further research???
So should I really go seek higher ground because global warming and a great flood are going to occur, or could this be the case of the media trying to sell a story and push an agenda? Remember, nobody is going to read a newspaper or watch the news if all is well... But " Your in danger... watch at 11" sure does get a lot of viewers.
