Global warming. Interesting "PRE" man hypothesis! link title

Replying to: ruking1 (Oct 24, 2008 5:00 pm) I thought one of the methane release scenarios was that burning carbon fuels was warming the climate, resulting in more methane getting dumped into the atmosphere from a warming arctic, making the cycle more vicious?

Replying to: steve_ (Oct 24, 2008 5:08 pm) So barring base line release studies in artic/antartic conditions, etc. weather scientists probably are unwilling to link the hypothesis (or make the leap just yet), as to whether you get greater or lesser releases  a-z temperatures. They already know and or surmise there is literally inexhaustible methane "locked" and at times (24/7) released by the massive H20 pressures exerted by oceans. |

Hundreds of millions of vehicles, hundreds of coal power plants, deforestation, agriculture, dams, cities...they all add up. The important question is what impact are we having and what if anything can we do about it. "The earth is dynamic; it heats and cools continuously. " What part of the earth are you referring to? The ocean, atmosphere, the mantle or the core? Just because a system is dynamic does not mean you cannot alter the rate of change or the amplitude. One of the keys to understanding GW and climate is getting a handle on all the feedback loops. Was the industrialization of humans responsible for the end of the last ice age? Maybe.... "New research suggests humans were influencing the world's climate long before the Industrial Revolution." http://news.mongabay.com/2005/0909-niwa_csiro.html "It simply an excuse to drain your wallet. " Spoken like a true non-scientist. What I find funny is that people have no problem dropping $40,000 or $50,000 on a vehicle just because of the trinkets they throw in. But if you mention anything to do with spending money on understanding GW they have a cow.

Replying to: larsb (Oct 12, 2008 7:00 am) " So Warm !!! Gary, every time you post something about coldness, I'm going to post something about warmness to show people that local weather is not global climate. Hit the Beach It sure didn't feel like fall on much of the Central Coast Monday, especially at some local beaches. Local residents couldn't believe how warm it was, but they said they will take it, because this unusually warm weather gave them a gorgeous beach day. Temperatures climbed anywhere from 80 to 85 degrees near the coast Monday, bringing a lot of foot traffic out, especially near the waters. Folks who live here on the Central Coast said they planned the day around the warm conditions. " I shall go on record now as to expressing imho that it will be an exceptionally cold winter. Please feel free to respond, I welcome a good spirited debate. Though it will defy global warming, in the near term as theory, I am willing to take the risk. Should my analysis not prove correct, I shall be the first to eat crow.Tia. |

Replying to: avalon02wh (Oct 25, 2008 11:32 am) Of course mankind has an effect; everything has an effect. But what is having the main effect. Well it is the Sun. The Sun effects the climate by warming the Earth an average of 520F. If there is no Sun the Earth is just a frozen rock in space at -459F. The Sun is putting out enough energy in all directions, to do this at 93 million mile distance. And it does this century after century after century. This BY FAR dwarfs any contribution mankind will make to climate change. That is why even small changes in solar activity matter greatly. One day there will be a great GW of hundreds of degrees, as the Sun grows in size. It is the Sun that determines our current and future. And since out orbit isn't circular or even constantly elliptical our orbt around the sun determines the climate of the Earth.

Replying to: kernick (Oct 27, 2008 4:31 am) That is the bottom line. Unlike, man made Global Warming Fanatics, I would like to see more LEGITIMATE research. I do not think any government is capable of Totally Honest research on the subject. Nasa and other Federally funded scientists have complained that their data was distorted or covered up by both Clinton and Bush administrations. Government agencies are usually taken over by zealots of one persuasion or another. That pretty well determines the results we see from the scientist they hire. I would like to believe that our Universities are capable of honest debate and conclusions. Even they seem to be over run with predetermined results on just about every scientific subject. |

Replying to: kernick (Oct 27, 2008 4:31 am) It might be a reason the "arm chaired" scientists do not assign numbers, %'s to "man's contribution: stuff like grandma/grandpa driving her cream puff weekly to bingo night, etc.

Replying to: avalon02wh (Oct 25, 2008 11:32 am) Let me be clear: I concur that all living things including humans affect the environment continually and that this has always been true. I also agree humans' present effect on the environment is greater than probably at any time in the past. This tells us nothing about whether human actions are of consequence in the context of all factors. What I find hilarious is not the question of whether or not humans have any impact on global warming; we may. However I think the default position must be that we don't until such proof is offered that we do. What I find hilarious is the doomsday predictions of some blindly believed by many that drastic climate change is only a few decades away. The same sort of predictions were made in the 1970s. These were largely based on the consistent rise in temperature in any number of major cities around the world. No one bothered to consider that these increases were due to the population explosion in those cities and were merely local events, not global. Additionally, temperatures have been recorded for a tiny portion of time relative to the earth's history. My previous post was simplistic; the point was humankind's impact on global temperatures is as yet unknown. Future predictions of catastrophe due to humans is a bit premature. Okay? I have no problem with money being spent on anything - just not taxpayers' money. Many well meaning organizations never solve problems because that would mean an end to their funding stream...
