You say:

"... scientist James Lovelock, who infuriated many colleagues in the science community when he publicly questioned global warming."

But I cannot find any reference to this. Perhaps someone could point me in the right direction?

Jonnie, Ayr, UK

The last few comments show how far climate change sceptics have gone in creating mistrust. You are idiots if you do not pay attention to science. This isn't a question of freedom of speech. If you present a program that is factually innaccurate or masquerading as science, you should be apprehended.

Hannah, Buenos Aires, Argentina

When all these pseudo scientists are proven wrong about global warming and fossil fuels, can I have my money back stolen in the name of "Green Taxes" ? I thought not. These environmentalists are worshiping the devil in the name of God.

James, Dundee, Scotland

I applaude C4 to have had the courage. It is no surprise that certain people seek to punish them now. Persecution and censorship - ideally should not be possible in democracies. Pluralism, freedom of speech & thought are great , precious values.

Richard, Munich, Germany

Good on C4 for showing this, and shame on the BBC/ITV for their lack of intellectual curiosity.
We, as ordinary people, are at the mercy of our news sources. When a theory becomes fashionable, it is important that we are allowed to hear both sides, and only C4 has had the integrity to attempt it.

Darren, Flintshire,

In north we've had rain, a lot of rain. Never seen anything like this, it's been raining like this in 1913. But, it's been cold as well, particularly June was cold, no more than 15 of C on any day, well below average.

I'm not convinced about any warming, as I understood it should hit us first.

Pasi , Finland,

The public don't want to believe that global climate change is happening. Is that really a surprise? This programme only serves to prove that point. As peer-reviewed scientific evidence mounts up, and as more extreme weather events happen globally, the global public will have to re-think.

Chris, Nottingham, UK

So, if that type of programme is to be censored, why is the BBC allowed to show Songs of Praise every Sunday? Pah! So much for freedom of speech!

Robert, Slough,

Anybody who still denies that global temperature rises, glacial melting, sea level rises, CO2 and GHG build up, the risks posed, and that this has been caused by human activity in the last century; has clearly not reviewed the IPCC report prepared by 2500 scientists and ratified by 130 nations

David Bristow, Madrid, Spain

Many people seem to think that mankind is too small to affect something as big as the atmosphere. It is just common sense, isn't it? And yet we have already increased CO2 levels by over 38% since the 1880s. This is like putting on an overcoat in the summer. Common sense: this is dangerous!

Tony, St Albans,

Where has the freedom of speech gone in Britain? If I wanted to broadcast that the earth is flat, I should be allowed to and let the others dispute my statement. Global warming is a natural event and pollution will not make any difference. There are many reputable climatologists who say that.

Brian J Deller,, Marbella, Spain

Credibility for global warming - or climate change as it is now called - was lost when this labour government used it as an excuse to exert more control over us and impose more taxes on us.

Ian Bitter, Salisbury, Wilts

The programme makers should not be hounded for their side of the debate on global warming /climate change. If the climate models are correct, remember they are only models of our complex Earth weather system, it is only right that they should be exposed to rigorous examination.

Keith Davies, Swansea,

If only an USA TV network had the guts to show the program, we would a lest be able to see the other side of the coin and be able to make a intelligent decision on global warming. But alas it will not happen because the networks have to much invested in a questionable theory.

Don USA

Donald Haslam, lacey, USA

seems to me this is the only country that suffers from global warming......they got great warm sunny climes in the med and i am sitting here freezeing on a typical ENGLISH SUMMERS DAY.......GLOBAL WARMING LOAD OF OLD BALONEY!!!

SUKI, BASINGSTOKE, ENGLAND

The program is pure bogus nonsense and offcom are just stupid , ignorant and culpible in not being able to talk to any scientist with peer reviewed literature on thi subject matter. It has been scientifically dissed many times but offcom cannot see that I suppose and believe the public.

Pete Best, Northampton, UK

The fact is that this programme presented the other, relatively rarely heard, side of the global warming debate, and not before time. You can't be angry because someone shows you the other side of the coin.

Nicholas Burns, Leeds,

Most Geologists don't believe in Climate Change or Global Warming as the public view it. We see it as a natural process occuring within an Ice Age climate thats just been sped up by human activity.

Roy , Thetford,

Global warming is a fact, caused when the Earth orbits closer to the sun. Conversely global cooling occurs when the Earth orbits further from the sun. Both natural occurences. The arguement is whether manmade pollution increases this process. Personally I don't believe it does.

Charles, Port Talbot,

Far too many scientific livelihoods in the form of 'research grants' are at stake if the public should ever stop believing the scientists who are making a comfortable living from frightening them.
Governments also have a vested interest (green taxes) in keeping the public scared as well.

D O'Neill, London ,

this proves global warming/climate change is a fraud. The truth supports itself, untruth needs constant reinforcement.
remember, the control of carbon is the control of life.

paul , waxhaw, usa

Polemicists have ensured that they have this headline to point to as comfort.

Still, I dont see that "An inconvenient truth" can ever be shown on british TV if this is the reasoning to follow.
