'5 ways to save the world' BBC2 (last night)

[All Day Breakfast]

Why did you study that and not something worthwhile like Coronation Street or the impact of the Archers on modern day society?

[A shed load of Daleks]

Has anyone explained the medieval and Roman-era warm periods?

Please?

You still look like a wasp.... but very fetching never-the-less... do you have a partner?

[All Day Breakfast]

I've been thinking for a few mins but I am still stuck......how exactly do you study plagiarism? Is it like arguing that grass is green and someone else saying it's not?

surely it's like arguing that grass is green

Now it's very clear that this board is full of IT people who are also experts in every field under the sun but I don't think basic physics is a very good skill to have when it comes to global warming.

One thought, if you are all experts then why aren't you putting your skills to good use by discovering cures for cancer, nuclear fusion and other such mysteries known to man?

I have a very difficult day tomorrow where I have to remove a very deep brain tumour, surely there must be a qualified brain surgeon out there amongst you who can give me some advice?

Maybe if you do a "google" then you can help me?

Erm, exsqueze me, but because you've done fsck all in your life doesn't mean that some on this board haven't done some very useful stuff along the lines you mention.

As a slight aside, I think something that is particularly worrying about this debate and others is how little 'the people' trust their government. This mistrust is clearly with good reason, but it is also potentially very damaging. There are many people now who will not believe a single word an authority figure tells them regardless of how correct or sensible it may be. What if there really is a problem that we all need to address for the sake of our own survival? We are in danger of not surviving because we simply won't believe them when they tell us. Think the little boy that cried wolf, except replace wolf with T-Rex who is going to eat the village. In conclusion, Tony Blair is responsible for us all being eaten by dinosaurs.

Actually, it is the inversion. If Tony Blair said global warming did not exist, then I'd be worried. As it is, because both him and Gordo say it's a problem, I know there is absolutely no need to worry.

Anyways, global temperatures are related to Solar output and cosmic rays. Nothing whatsoever to do with the piddling amounts of CO2 humans have pumped into the atmosphere.

I refer you to the the links above. I can't spoon feed you the answers - you wouldn't believe me anyway. Why not do some research before posting?

1. I believe that he had done some research, (i.e. like yourself he did a bit of googling)
2. Why can't you spoon feed him the answers? If you are are so sure that this document provides definitive proof and GW is attributed directly to human activity you must have read it thoroughly, isn't it your duty to help others understand for the good of the planet? I asked where in the document you link to it explains previous warming/cooling cycles, you haven't actually read it, have you?


Edit:
I found this in your report:
"Changes across the last 500,000 years

It is very likely that large and rapid decadal temperature changes occurred during the last glacial and its deglaciation (between about 100,000 and 10,000 years ago), particularly in higher latitudes of the Northern Hemisphere. During the last deglaciation, local increases in temperature are likely to have been as large as 5 to 10°C over a few decades. Over the same period there is evidence of less pronounced but nearly synchronous changes worldwide, except in high southern latitudes.
Antarctic ice cores have provided new evidence of almost in-phase changes of temperature, carbon dioxide and methane through the ice age cycles over the past 420,000 years.

There is emerging evidence for significant, rapid (time-scales of several decades or more), regional temperature changes during the last 10,000 years. However, the evidence does not indicate that any such events were global in scale. "

The first highlighted section appears to indicate that there were changes in global temperature before we started driving to work.

[zathras]

it's poppycock.

Where to start.

1. When given historical data, no climate model has accuratly predicted current temperatures except one. That does not use carbon but solar activity as the driver for temperature.

2. Analysis of core samples shows that carbon increased after, not before an increase in temperature

3. Vikings; established colonies in Greenland, Newfoundland and North America. These colonies were for the collecting of wood for ship building. There is an ice sheet over Greenland, not trees so that must be colder.

4. Analysis of Glaciers show an increase in size in the majority, not a decrease

5. In 1421 a fleet of ships from China (just before the Ming dynasty closed off China) travelled around the world. One of those ships travelled East through the North Atlantic; then over Scotland, up the East coast of Norway, over North Russia and thence via the Beiring Straights to the Pacific. Try doing that in a modern ship let alone a (large) Chinese junk.

6. During the mini-ice age Polar Bears where spotted in the Orkneys

7. Scientific consensus. There is n't one, plenty of scientists disagree that the current global warming is down to Man. Further if there was this is not a very good justification. Gallileo would happily agree that the Scientific consensus of his time were talking out of their collective rear-ends. They have been doing it ever since.


8. Carbon is not even the largest contributor; it is beaten by both Methane and water (in the form of vapour or clouds).

9. if it is so important why is it that the only result of the recent Stern report (written by an Economist and do you know his terms of reference) was an increase in taxes. Where are the tax benefits in using non-polluting forms of energy production such as personal windmills, geothermal, water etc?

Heretic!

Burn him!

No hang on, that will release CO2

Hang him!

In order hang someone you have to boil the rope to stop it stretching. That creates Co2 and water vapor.
