BBC's biased reporting of Global Warming

[jsn112]

And yet if you look at the trend line of all those points you'd notice a fairly decent upwards slope by taking midpoints (eyeballing it, starting from about -.2 in 1979 and going to about +.25 in 2010 - that's about a change of nearly half a degree in 20 years).

As for that arrow, so what? In 1984 there was a point that was at -.6. In 1993 there was one nearly at -.5.

A single point along a graph like this, particularly one with multiple data points per year crunched into a 30 year graph, isn't particularly pursuasive. You have to show that the red line is going to head down, and permanantly down. If that point represents the "low" similar to the lows of 1985 and 1993 then we have a MASSIVE problem.

Why? Then the absolute low of lows has moved from being a -.6 to a 0. That's a HUGE increase in the minimums.

Thank you GreatCloud - you've proven our point. AGW is very, very real.

That's not proven your point in any way, shape, or form. Even if he did, you're going to hang your hat on 0.1 or so degree?! Are you serious?

If there is an increase trend, you have to question where were the sensors placed to take the temperature readings. Sensors located next to the heating vents and etc. are not an ideal place to take a reading.

Your graph shows an overall upward trend. Do you think that proves your point or disputes it?

The graph only shows thirty years of data, and I don't see how we can make many conclusions from it. This may be a time period that is on a positive slope in a very much longer cycle of change. There are scientists who research much longer cycles, such as the Milankovitch Cycles which include precession, obliquity, and eccentricity.

I'm not a scientist and do not have a firm view on AGW, but I am very intersted in ALL the science involved.

Where do you get a change of 0.1 degree C? We're talking at least a 0.5 degree climb over 30 years (which is an INCREDIBLY small scale when we had less carbon in our atmosphere and, due to development in India and China, were emitting far less then than now). Heck, if we measure the "low" points (like the one GreatCloud has an arrow pointing to) against the first "low" point on the graph it's a change of 0.6 degrees C.

As for the science, yes - there is science going on. 95% of it or so points to us having an effect on the climate. What dissent there is tends to be about questions of degree and not questions of whether or not it actually happens.

Continuing to drop here is the latest graph of the current minimum. How long will it last and is GW finally over ?

You know there are cycles, long term and short. What would've been expected given the cycle we are currently in?

What this graph shows is a very short period of one of the warmest decades on record.

Daisy it also could signal the end of that 90's & 00's warming and the begining of a Maunder or a Dalton minimum. It is after all a record cold for La Ninas.

Now Why would God go and make a Planet that does not have a stable climate

First off, I was hoping you'd be able to self identify which of Sun-Tzu's strategies you feel you employ (I'm leaning to the last of the three after this last post).

Because it's dumb to argue pseudo science

It's not pseudo science. You just don't like it.

I proposed last year that if the increased trend in global temperature about 1 degree every year (or whatever many year), then would you agree that in 10 or 20 or 30 years the global temperature would be increased by 5 or 10 or higher degrees?

It's really hard to argue with someone about science when they have trouble with their own basic math.

Now, that's hard core evidence.

What? Hard core evidence is you saying "what if"? Do you know what evidence is? Do you know what homeostasis is? Do you know how statistically significant the current warming is relative to past cycles?

Otherwise, 1 degree is a sneeze

Wow. You know absolutely nothing about the planet. That is embarrassing to make that claim.

According to your charts, I want to see 2 or three degrees increase in this summer. That's not hard to ask, is it?

I don't know. Talk to the laws of physics; they could probably answer that question for you.

A record, but not the record? So what is the record?

La Nina is a cooling cycle, so wouldn't we expect temperatures to be going down during the cycle?

La Niñas, which occur when sea surface temperatures across the equatorial central and eastern Pacific Ocean are below normal, play a significant role in the overall weather pattern across the globe. The current La Niña has been influential in 2010's extreme events....

So why are these extreme events non-typical for a La Niña occurring? The answer is complex and complicated. But in general, all La Niñas are different. While general trends have been observed throughout recorded history, no two La Niñas are identical.

Variations in strength of La Niñas also lend different results. In general, the stronger the La Niña (or the bigger the departure from normal in sea surface temperatures in the central and eastern Pacific), the more extreme weather events we'd expect to have. The difficult part is determining where these extreme events will occur and whether such events will occur with regularity.

Infrared satellite data, which currently is the primary means of measuring sea surface temperatures, has only been available for about 50 years...

She (the weatherman quoted above) said that this la Nina isn't expected to last past this summer.

Daisy global temperatures are going down

This graph shows temperatures are dropping drastically in just over 1 month. This is in correlation with the La Nina pattern.

I seriously doubt if the Yanks even know what the BBC stands for and how its track record speaks for itself. BBC documentaries are not only unbiased but are well researched and extremely well made. If one word comes to mind when I hear the name BBC; It is "QUALITY"

When I think of the BBC, I think of "Planet Earth" and "Life." I have both series on DVD.

 

[Belk]

You know...this is like wandering into the psych ward by accident. Do you people actuallly exist in the real world?

Are you truly so incapable of handling the fact that people have different thoughts and opinions? Is insulting them the only way you know how to react? Might want to work on that a bit if you plan on dealing with disparate groups in real life.

My wife's got most of the David Attenborough documentaries. She loves them. They're not really my thing, but even so - I know quality when I see it, and they've got it in spades.

Not wishing to turn this into a "promote the BBC" thread, but I can highly recommend Professor Brian Cox's Wonders of the Solar System - a perfect follow-on to Carl Sagan's Cosmos.

And Doctor Who. Of course.

David.

But a drastic drop in just over a month is just a blip compared to the general upward trend that's been observed over the past few decades.

It could be that this drastic drop represents an end to the warming. It could also be that it's just an anomaly.

One of the BEST docudramas EVER made is BBC's SPACE RACE! I must have watched it more than 30 times already!

The day they close down BBC is the day Erudition will die!

Doctor Who was actually pretty rubbish the last couple of seasons. Tennant's second season was the best, with the Master to conclude it.

The BBC's documentaries are second to none. I am looking forward to Natural World tonight, but Human Planet is also fantastic.

The past two decades of warming is not significant we have had warming periods that were global before. The Roman warm period the medevil warm period and global cold periods the little ice age. To say that this warm period is different has not been proven.

La Nina is a cooling event, right? What happens when it is over?

The context of this warming period is certainly different, though. In that, the previous ones hadn't been preceded by mankind chucking an increasing amount of pollutants into the planet's atmosphere, its water, and its land.

1) Why do we only talk about the last two decades? There has been warming for some time and, had it not been for the advent (release and usage) of CFCs and other aerosols, it would have been even more pronounced. Regardless, I'm not sure that warming in recorded history has been this abrupt.

2) You talk about two "Warm periods". Care to provide links or information for that?
