Questions about Global Warming.?

Question

With Al Gore scaring everyone into believing catastrophic events are about to take place on earth due to global warming, I have a few questions about this topic:

When the last ice age took place on earth, what caused the ice to melt?

In a 1975 Newsweek article, scientists were certain that the earth was going through "global cooling". What has changed since then?

Landfills emit methane gas. What do global warming fanatics do with their garbage?

It is a scientific fact that the grand canyon has been under water nine times since the beginning of the earth. How did that happen?

Answer 1

In most glacial periods the ice and snow prevent weathering of rocks and therefore slow down the part of the geological carbon cycle which removes CO2 from the atmosphere. With higher CO2 concentrations the greenhouse effect becomes stronger and provides a warming influence.

There are still scientists who believe the Earth is cooling.

Global warming fanatics produce as much greenhouse gasses as anbody. They just whine about it more.

It's amazing what a little water can do over millions of years.

Answer 2

ICE AGE
The ice melted because of global warming. The current period of warming started about 18,000 years ago, it took about 7,000 years to bring the ice age to an end. Since that time the world has continued warming. This has been a general trend, there have been cooling spells as well.

GLOBAL COOLING
As mentioned above, there have been cool spells but the general trend is of warming. Imagine your house... cold outside but inside the heating is on and your house is warming up, someone comes through the door, cold air gets in and your house cools down a bit, it soon warms back to the point before the door was opened and keeps warming as long as the heating is on. In terms of global warming there have been many doors openings, the most recent was 1992 to 1995 following the eruption of Mount Pinatubo which emited so much volcanic dust into the atmosphere it blocked out sunlight for 3 years.

Global cooling has been seized upon by thise who seek to disprove global warming. Scientists examined global cooling, a good scientist will examine all options. There are people today who study global cooling. Unlike now where the scientists are ringing the global warming alarm bells there was no bell ringing back in the 1970's. It's something that has been distorted and exaggerated.

METHANE GAS
I guess a lot of 'global warming fanatics' are environmentally conscious and recycle as much of their garbage as possible thus reducing the amount that enters landfils and incinerators. Methane produced by cows flatulence is a bigger problem (seriously), as is the methane being released from the Siberian peat bogs which until the last few years was trapped under a permanent sheet of ice.

GRAND CANYON
Couldn't find any specific info about the Grand Canyon - do you have a link?

The Grand Canyon itself is quite a recent feature on the earth's surface being between 5 and 6 million years old but with most of the downcutting having occured within the last 2 million years.

There's nothing to suggest it's been underwater 9 times in the last 6 million yeras. However, the erosion has exposed strata laid down over 2 billion years, nearly half the age of the earth.

We have climate records going back a little over half a billion years (based on oxygen isotopes) and we know that in the last half billion years there have been 4 periods of glaciation (we're in one now) and four periods of non-glaciation. Perhaps this accounts for the starta exposed by the Grand Canyon being underwater several times, or at least four of the instances.

Answer 3

It seems like you are using the natural cycles of our planet to explain what is happening, or downplay the human role in climate change/global warming. Although the planet does have it's own natural cycles of heating and warming, this is no reason for us to create an artificial one right now, as this will cause massive disaster world wide.

This is the way that I see it. When you were a kid, you were told not to play in the street. Well, this is the same thing. If we continue the way that we are, then we're playing in the street, and we can get hit by a car. The skeptics do not say that pumping these gases into the air will not have any effect, instead what they say is that the levels we are pushing is not enough. The other side says that we put more than enough to change the climate. Like playing in the street. You are not going to get hit by a car right then, but if you stay there long enough, you will. So let's play on the cautious side folks, and stop playing in the street.

Environmental expert decries 'hypocrisy' of Gore, greens

A climate change expert says Al Gore and other proponents of catastrophic manmade global warming are not only pushing flawed science, but also demonstrating hypocrisy while pushing their cause against what they consider a dire threat.

Former Vice President Al Gore recently announced a series of worldwide concerts to focus on the perceived threat of global warming. The "Save Our Selves" campaign will feature events in seven cities on July 7 and musicians such as Snoop Dogg, Bon Jovi, Kelly Clarkson, Faith Hill and Tim McGraw.

Dennis Avery, an expert on environmental issues at the Hudson Institute, says he doubts Gore and the environmentally conscious singers will forego taking a private jet to the concerts. "I think the worst hypocrisy is the guilt trip that the green movement has offered to all of us," he says. "And people are enthusiastic about being Al Gore's side, if they're non-scientists, to prove that they're socially responsible people [or] to prove that they're 'good' people. And I think it's nonsense."

Avery says he cannot agree with the explanation that the warming prior to 1940 was caused by human-emitted carbon dioxide (CO2), because 80 percent of the CO2 was emitted after that. "So if we take away 0.5 degrees of the warming from before 1940 and give human-emitted CO2 half of the net warming since 1940, that comes to 0.15 degrees ... over a 150 years," he says -- noting that occurred during a period "when the laws of physics say each additional unit of CO2 will have less forcing power than the one before it."

Avery is co-author of the book Unstoppable Global Warming Every 1,500 Years. Avery claims over the last 20 years, he and co-author Dr. Fred Singer have documented globally from dozens of different proxies a "natural solar-driven moderate" 1,500-year climate cycle. He says he is "greatly despaired," however, that no one is telling the public about it.

Answer 5

Interesting, none of your rant about history disproves the facts about the exponential growth in green houses gases currently so your point is ?

On the real side, you probably won't be able to stop it anyway because your religious right wing cousins successfully opposed birth control . . . the lone shot at mitigating the problem.
Everyone is going to get whacked , even you .

Answer 6

We should keep the earth clean to protect us and our food sources.
Global warming...part of a natural cycle??? or a message of survival???

Answer 7

If we were going to do away with all the hot air pollutants Al should be the Frist to go.

Answer 8

Agreed that temperatures fluctuate. That doesn't mean we are excused from being good stewards of this world.

Answer 9

Why don't you go and some research regarding this stuff.
