What do you think about Global Warming?

I have faith that life will make whatever corrections are necessary for its survival. It has survived 90% extinction rates before, and it will likely survive humanity. And we thought 'survival of the fittest' meant being the biggest and baddest. Oops.

Sounds like Mad Max.

Can a scientist unequivocally show me some proof that the earth is warmer today than at any time during the last 650,000 years. I watched the movie for the second time in the last 10 days last night. Just wondering? I thought it was a mistake for him to use hurricanes(Katirina) to try and make his point.

You mean this? :

http://en.wikipedia.org/wiki/Image:C...ature-plot.svg

It plots CO2 levels along with temperature. As you can see, the earth does have a tendency for cyclic phases of warming and cooling, but most importantly, it also tracks closely with CO2 levels.

Present CO2 levels are much higher than in the past 650,000 years.

I don't pretend to be a scientist, but the mark on the graph for present CO2 level does not correspond to any of the raw data when I clicked on the CO2 level for both of the links to CO2 levels. What am I am I missing?

You mean present CO2 levels? 365 ppm?

Sorry for linking to Wikipedia so much... I'm getting ready to go to work, and I don't have the time to find any less pedestrian sources.

Again I am not a scientist but if CO2 levels were this high nine years ago and continues to increase at those graphed rates wouldn't the temperature be much higher today?

So temperatures are higher now than they have been in 650,000 years?
[/b]

CO2 levels are higher than they have been in 650,000 years. If the relationship between CO2 and temperature are as scientists believe then yes, temperautes now are higher than they have been in 650,000yrs. If you judge them on climate and not weather.




650,000 years of greenhouse gas concentrations

Some can and will argue about Vostok and Dome-C low resolution but that is not the only evidence they have to determine GHG levels and temperature in "pre-history". Geochemists have been using data like oxygen isotopes in coccolithophores, cap carbonates, dendrochronology and various other methods of comparing data.


Similar to a report summary I did on ocean acidification and its effect on calcifying organisms.

Kinda messed with my professor's head a bit because on the 2nd day of class he stated that he fully believed that global warming was happening but he wasn't too worried because CO2 uptake by calcifying organisms in the ocean would help mediate the problem. Lets just say he was VERY interested in this journal. lol

2005 and 2006 were the warmest years on record for two years in a row... but if you're talking about why the orange line on that graph isn't keeping up with the blue one, bear in mind that 9 years doesn't really show up on a graph that is 650,000 on the X axis as much more of a statistical error .

Here's a more detailed plot of the last century and some change.

Warmest years on record worldwide, in the US? How long have records been acurately kept?

Ah... it looks like we have a real scientist in the house! I'll let you explain it better than I can.

Do you have any links about the highest yearly global average temperature? I would like to read about it.[/b]

Malorn, it is clear that you are asking non-scientists to provide scientific evidence. I'm sure you relish in our frustration for not being the climatologists we wish we were. I am not a scientist nor do I claim to be. I choose to leave the research and the documentation to the experts. Any arguments with the data provided should be addressed with the authors of the data itself.

Since there is no reason to retype everything that has already been very well documented, please read the following web page in its entirety including following all the links provided. I am confident that most/all of your arguments can be located if you look hard enough. I have neither the time nor interest in attempting to win this no-win argument. The best I can do is provide this link and let you be.
