Ssssssshhhhhh, don't mention Reform.

Roman Warm period anyone ?

Lots of warm periods in the past, so what? The difference now is that it is man made. We are causing it, the Romans didn't.

 

[Mottie]

Climate alarmists rarely talk about the Roman Warm Period, as they are happy to let sleeping dogs lie.

Must have been warm in those days. I’ve only seen pictures of old Romans dressed in toga's. Never seen one in a fur coat.

Do you have a link for this:

You piped up claiming that everything was lies whilst I was typing my comment saying that you would do just that.
I was right again.
Does it really, really, really grate on you that all the people you look down on as being thickos, always prove you wrong?

With no evidence.

I think there is some evidence for some of the factors. But I haven't looked properly for a long time. I can understand why sceptics won't accept the explanations.

I can't, it's about as simple a science gets. We put things in the atmosphere which trap heat therefore the earth gets warmer.

Go figure - the CO2 levels were les than now and yet the temperature was higher

Temperatures

That is wrong.

1) some regions were warmer, some were very much cooler

2) the period had higher than average solar radiation

3) less volcanic activity






evidence suggests that the Medieval Warm Period was in fact warmer than today in many parts of the globe such as in the North Atlantic. This warming thereby allowed Vikings to travel further north than had been previously possible because of reductions in sea iceand land ice in the Arctic. However, evidence also suggests that some places were very much cooler than today including the tropical pacific. All in all, when the warm places are averaged out with the cool places, it becomes clear that the overall warmth was likely similar to early to mid 20th century warming. Since that early century warming, temperatures have risen well-beyond those achieved during the Medieval Warm Period across most of the Globe. This has been confirmed by the National Academy of Sciences Report on Climate Reconstructions. Further evidence (Figure 1) suggests that even in the Northern Hemisphere where the Medieval Warm Period was the most visible, temperatures are now beyond those experienced during Medieval times.

Secondly, the Medieval Warm Period has known causes which explain both the scale of the warmth and the pattern. It has now become clear to scientists that the Medieval Warm Period occurred during a time which had higher than average solar radiation and less volcanic activity (both resulting in warming). New evidence is also suggesting that changes in ocean circulation patterns played a very important role in bringing warmer seawater into the North Atlantic This explains much of the extraordinary warmth in that region. These causes of warming contrast significantly with today's warming, which we know cannot be caused by the same mechanisms.

Are you incapable of acting like a grown up?

Must be a different sun now then.

OMG I hope he doesn't look down at me, he only has an o level in woodwork and an Art o level.

Sorry to pull you up on that but Notch doesn’t call those that disagree with him "Thicko's".









It’s "Ficko's". Get it right.

There are several events like that, such as the Little Ice Age and the Medieval Warm Period. But the explanation given is that these were just regional events caused by things such as temporary changes in sea currents. They weren't global temperature changes. They definitely cause a lot of confusion, though.

I don't think that the Romans made it as far south as Australia, Madagascar, or Uruguay, for example, and therefore couldn't take measurements from there to see if these variations were global.

It is well known that solar activity runs in cycles.
