indeed, CO2 will help repopulate the oceans and that is important. but if the oceans' pH changes appreciably in the next few decades, that is only going to be a bigger problem, exacerbating the lifelessness of the oceans. and that might be okay on the timescale of hundreds of thousands of...

Andre, thank you very much for the explanation. i do appreciate the work you do. and even though i agree that the warmers and skeptics have a few miles between them - well beyond hearing distance - i don't think that that means we should yell. that is, i don't think that ranting or polarizing...

This is the kind of thread I like. Those are nice plots you put together, but I have to say that atlanta trend-line looks to be pretty statistically unconvincing. And the three to the far left are all that's tilting it. All having remained the same population they could all be related in...

Well, Andre, money plays a big part in US politics. So when people see scientists funded by big oil/coal coming out with results supporting industry and disagreeing with most other science they react cynically. No matter how big the alleged 'global warming lobby' is, i can guarantee you the...

Experiments have shown that CO2 increases raise plant growth levels fairly equally across species. I could swear some one posted the link in this forums the past month or so. I don't have the Mozilla physicsforums.com searcher, maybe some one could try and find this for us? Though I do...

Yes, those headings in the article are rather misleading and the author doesn't seem to explain his reason for claiming the lakes may be growing. I've heard about the problem of large glacial lakes in asia possibly flooding people downstream before, so i think there is some reason to believe...

I've read a lot about global warming, etc and have never seen anyone (scientists, oil execs, etc) claim the known accessable oil will last much beyond another century. just last night i saw some one discussing a book claiming the peak will be in the next two or three decades (sorry, i can't...

me too...

the total mass of Earth and its atmosphere has not changed and that is what determines the Earth's gravitational force. the overall mass of the atmosphere has only changed very very slightly, if at all, due to CO2 emissions. in addition, the EM forces of the Earth's magentic field have a...

Actually, the red #3 data is not the result taking random data and putting them through Mann's methods/calculations. Rather it is the result of taking the black #1 data (a simulation of the global temperature the past 1000 years produced with the ECHO-G simulation), producing theoretical proxy...

If parties A and B were well-educated scientists and all the evidence had been pulished in peer-reviewed, referreed literature then I WOULD expect that A's final response would be 1. ("whew, we're off the hook. AGW isn't happening") PLEEEEEEAAASSSE don't be so cynical, Andre. Most of the...

yes, please do proceed, andre. i'm particularly interested in the conditions under which these animals would have frozen. that is, if the local climate appears to have quickly become cold or if it slowly cooled and the mammoths died in normal (for them) cold weather. do they know if these...

yes, that's probably the realistic outcome. i was thinking of a more unrealistic case where there is an open tunnel through the Earth helf open by some sort of (very very very) strong supports so that the rock would not collapse. i guess i would also assume a vaccuum. since, even if you...

Nope. In fact, there'd be essentially no gravity. Not from the Earth anyway. Since there is no gravitational effects at the center of mass for a uniformly mass-distributed spherically symmetric object. All the gravity forces of the various pieces of Earth cancel out because they are...

That Muller article is very good. Distilling out the problems of one of the AGW alarmists' pillars supporting their urgency. However, his balanced and, more importantly, very thoughtful comments do not argue that CO2 is not a problem. As he said, I realize he is just one scientist and...
