Global Warming Advocates please answer this for me?

Question

Using your (and Al Gore's) rational that human pollution is causing global warming, how do you explain the "Medieval Warm Period" which lasted between 900AD and 1300AD? A several-hundred year period of warming, this event obviously took place long before man developed any ability to pollute on a large scale. If you like, you can read more about this event here: http://en.wikipedia.org/wiki/Medieval_climate_optimum

I'm not saying the Earth is not warming. I am simply wondering how one can yet say the warming is caused by man, and that all serious scientists consider the debate over (as Gore has)?

IndeXed... Using your logic we cannot compare today's temperatures to any time before there were weather stations and satellites all around the world. So we couldn't say anything about today's temperatures versus the last 100, or last 1000 years.

Answer 1

There are a lot of causes of natural temperature variation, like solar activity cycles and changes in the earth's orbit. These no doubt caused the MWP -- a period in which the average global temperature rose by a whopping 0.2 degrees C over a century or two. Big whoop.

The current human-caused global warming has raised the global temperature by THREE TIMES that amount in a century -- yet global warming denialists insist that it's, well, just a coincidence that this is occurring at exactly the same moment in geological history when the level of atmospheric CO2 is greater than at any time in the past 2 million years. How credible is that?

Answer 2

As to your link--the answer is right in the text. A massive solar flare from the sun caused an increase in carbon which explains the whole event. I don't know about you, but when the leading scholars and experts in the field produce reports that state the facts--I tend to believe them. When global changes that are scientifically linked to the only thing that could possibly cause them--I tend to give them credit. When the corporations that are mainly responsible pump funds into the campaigns of only those candidates that make statements denying global warming--I tend to not believe them.

When the last report on the Greenhouse Effect, written by the expert in the field from NASA, the Bush legal appointees gutted it and dumbed it down to point of irrelevancy. Now why would he have such a thing done? And finally, just because Al Gore believes in something, it doesn't mean you don't have to!!

Answer 3

I'm not a global warming advocate... wait, who the hell advocates global warming? Global warming is a fact. Even morons (except the one in the White House) know that global warming exists. You are right to point out that the cause of the current climate change is questionable? But nothing comparable has ever happened in history. There are many indexes you can use to easily see how fast it is occurring. The easiest thing for someone like you to do is to suck it up and watch Inconvenient Truth. Pres.Gore (oops! Not yet!) Mr.Gore lays it out very straight forward.

Answer 4

the medieval period is a good start but get them to explain how 300 million years ago. the earth was so hot that it is estimated just a few premamalian animals were able to survive. the water dried up to almost nothing. what they believe we descended from ate bulb plants underground for water. but the planet adapted and a sturdy plant began growing and releasing o2 which is when the beginnings of the rain forrests began. Mother nature is an amazing thing and can adapt.

Answer 5

I agree with what the man put forward and agree with the science he has presented. Unfortunately no one is listening as it seems even you haven't noticed a change in the weather during your life- you must be young- bad things are coming unless a lot of changes happen relatively quickly. The real danger is to much fresh water being introduced in to the seas- especially the Atlantic. The science is relativity simple so even you should understand it

Answer 6

You are slightly off on your time line.

I would start your quest with the 565 event that caused global cooling for 300 years.

Check out the Secrets of the Dead program Catastrophic Event.

Answer 7

When will we learn, man cannot control the weather
or the climate. Not too many years ago, we had global
cooling. It comes and goes in a cycle, and nothing we
do will ever change it just as we cannot stop snow
storms, tornadoes, or the sun and moon rising and setting.

Answer 8

I am almost sure in 900AD they could not track weather and the ozone like we can now.....ya know ......CAUSE THE LACK OF SATELLITES AND WEATHER STATIONS ALL OVER THE WORLD????

Answer 9

because the rate the earth is warming up this time is just to fast compared with any other age, and it all starts with the industrial revolution
