Re climate change, Has there ever been a time on earth when our Climate was not in the process of change?

The climate always changes, sometimes slowly and sometimes rapidly. What we're experiencing now, if anything, is just another example of "climate change." We were never promised a stable climate. Levying extra taxes of any amount, is not going to change the way the weather comes to us.

Climate changes for various reasons and/or a combination of reasons. Science is based on data and physics. Nothing can happen in the natural world that conflicts with the laws of physics. All data must fit within the laws of physics or be rejected. However, if the data does fit within the laws of physics it must be included. Climate has changed because of such things as changing ocean currents, the movement of continents, the introduction of atmospheric pollutants, the orientation of the Earth to the sun, lifting and subsiding ocean beds and the building and erosion of mmountain ranges. All of these things are done at a geological pace. A sudden aasteroid strike could alter the climate suddenly or a hundred year series of massive volcanic eruptions could do the same over a slightly longer time period. The physics of these things don't change and the data that illustrates these things is, or it isn't. In our time, the era since 1800 and now has been an era of burning massive amounts of fossil fuels. The data shows that is a fact. Burning fossil fuels adds CO2 to the atmosphere. The data shows that's a fact as well. Some of this excess CO is taken up by plants or by oceans....nobody has denied that this is a natural function. Some of this excess CO2 helps to create a 'greenhouse' effect. Nobody has been able to deny the physics of this phenomena. A 'greenhouse effect' results in a warming trend as less energy is emitted from the Earth's surface than is introduced. Nobody has proven that this aspect of heat physics is wrong. Therefore, the data...a sharp increase of man made CO2 fits into the physics of the natural laws associated with planetary heat retention. There is no counter argument...unless someone managed to repeal the laws of heat and atmospheric physics, which they haven't and they can't!

Nope. It has always changed for a variety of reasons. The Medieval Warm Period and the Little Ice Age are just two well-known examples. Has it always been impacted by man? No...but it may have been impacted much further in distant antiquity than you think. Neolithic farming practices and related deforestation may have impacted climate. Also, Paleolithic peoples' use of fire may have also impacted climate. And yes science does change, because, unlike ideology, it is flexible and responsive to knew information.

Nature abhors the "same old, same old," so despite what our senses tell us, the world is changing. Weather and the longer trends, climate, are no different.

Judge for yourself by checking out a graph derived from Greenland ice core samples (http://bit.ly/caJLxv) and a graph of temperature derived from the Vostok ice cores taken in the Russian sector of Antarctica (http://joannenova.com.au/globalwarming/graphs/Vost...

Consider the Minoan Warm Period, the Roman Warm Period, and the Medieval Warm Period. All of these periods saw higher temperatures than anything we have yet experienced during the current warming period.

The coolest of those three was the Medieval Warm Period around 1000 CE to 1300 CE. It had estimated temperatures 1-2° C above the normal period of 1931-1960. In the high North, it was even up to 4° C warmer making Viking travel between Iceland and Greenland rarely hindered by ice. Viking graves in Greenland which were dug in moist ground still lie in the permafrost.

The only constant in climate is change.

No, the climate has always been changing.

And some people have always been arrogant enough to think they did it.

There are 880,000 tons of atmosphere per person. We're simply incapable of making an impact of any significance on it. It's too big.

Then why is it called the IPCC and not the IPGW?

Climate change science predates the global warming label (really on in public use since 1988) by decades.

Your scientific illiteracy, general ignorance of the issue and warped political bias are showing. You never took that whole "education thing" seriously, huh?

Climate is always changing.

In fact, climate change has been responsible for most mass extinction events in the earth's history.

What's happening currently to the climate is in the beginning stages of causing another.

In fact, species are going extinct at a rate already, that would mark the present time, as a mass extinction event in the earth's history.

This current one is preventable.

Global warming causes a change in climate. This was true before, it is true now and it will continue to be true. The terms Global warming and climate change have always been used. Both of them.

You can sit there and argue all you want, it doesn't change reality.

There is no such thing as a static climate. Nature is always dynamic and changing.

If the climate isn't cooling, then the Globe is Warming.

If the climate isn't warming, then the Globe is Cooling.

Only political hacks use this dynamic and blame man as the reason so they can profit from people's fears and ignorance.

No, climate has never been static, but that's not the point. It is the rate of change that is important, and if mankind is accelerating the rate of change, or pushing the climate rapidly in a particular direction, it matters.

Your question is like saying that there has never been a time when the land was not eroding on Earth, so it doesn't really matter if I push a boulder down the hill onto my neighbor's house.

The climate is always changing.

That's why it's ridiculous to point the the changes since they started measuring and insist that we caused them.
