Should we do more to prevent global warming?

Scientists say we need to cut our emissions by 80% by 2050 just to keep climate change within two degrees centigrade of current world temperatures. Can Ethical Men and Women tackle global warming on their own?

Newsnight's Ethical Man Justin Rowlatt has just completed a 6,500 mile trip across the United States in search of solutions to the biggest problem on earth.

He discovered that each American is responsible for 20 tons of carbon dioxide emissions, more than twice that of the average European.

But the country is also the most innovative and powerful nation on earth whose president says he is serious about tackling global warming.

Have you changed your life because of the threat of climate change, and if so how? Should the US do more to tackle global warming because it is a bigger polluter? Has the time come for everyone to take responsibility and do their bit?

Prove to me that there actually IS global warming and that it isn't part of a natural cycle and maybe we should start looking at it.

You cannot even make a dent in global warming, or environmental destruction, until you STOP population growth.

Population growth outstrips any and all environmental gains so quickly, that all other efforts are ineffective, and will continue to be so, until we face the fact there are too many people being added to the resources drain, every day.

If global warming, caused by man, is a reality and life on earth faces eventual decimation why is the answer from politicians, who have surely seen the proof, that it is okay to carry on the way we are but we should just pay more tax?
Why do we need more housing which will cause more global warming?
Why do we need to expand airports?
The biggest problem facing the earth is over population but no politician in the establihment parties of all the major nations even mentions it.

Ho-hum, here we go again. was wondering how long it would be before this tiresome topic was featured on HYS yet again.
How many more times?
GLOBAL WARMING is a massive scam invented by Al Gore in the 1980s and has ever since, been hijacked by MPs, celebs and other easily-led people as a means to tax and restrain the masses.
Meanwhile, CLIMATE CHANGE is a naturallly occuring event that cannot be prevented.

Global warming is real, but it's a natural event that has nothing to do with mankind, and there is nothing we can do to change it in any way.

Have a look at just how many of the scientists involved in the IPCC report that are now distancing themselves from the conclusions drawn.

Somebody did not get the memo...It's climate change now, not global warming. You can only protest global warming in a driving snowstorm so many times.

Sure and in the meantime carry on polluting the planet and using it as a trash can?

We will run out of fossil fuels soon anyway, so the issue of global warming is irrelevant. We have to change to renewable sources ASAP, regardless of whether or not man-made global warming exists.

"Prove to me that there actually IS global warming and that it isn't part of a natural cycle and maybe we should start looking at it."

The problem is that absolute proof requires waiting to see if the disaster actually happens or not. If a doctor told you "we need to innoculate you against a disease even though we don't have absolute proof you will catch it - we only get that if you drop dead from it!"...would you hesitate?

I am going to fight any attempt to regulate carbon emissions with whatever resources I can muster. You have overplayed your hand BBC, the scaremongering, the bias, the skewed data and stunts like sending this clown to Vegas to wag his finger have shown that your reporting can't be trusted.

it,s nothing to do with global warming.its a natural cycle that will occur every million or so years,it,s just come at the time this government was looking to make more money in taxes from the taxpayers of this country, so along comes the green tax... which will do absolutely nothing to improve or stop, what is a natural cycle.it dont matter how much tax or restrictions on coal,cars..etc it will still continue to complete the natural cycle. just another underhanded tax burden.

Its all too little too late.

Highly ironic topic considering 'HOME' the new documentary film released only 2 weeks ago has had zero coverage by mainstream press or news?

The painful truth is that its already too late, and this is mostly the fault of industrialist/capitalist ideals exhausting all natural resources on the pre-text of never ending growth. With no regard for the welfare of the planet long term. But I guess there is no profit to be gained through responsibility!

"If they are going on about greenhouse gasses not being able to escape into outer space, how can they get in because if the same semi-permiable membrane is stopping them getting out"
Peter, Great Britain

Aargh, Seriously? The gasses are produced on Earth through both natural and man made events. Space is (practically) a vacuum, gasses don't come in from space. Maybe this is why the scientists have a different view to many people - becuase they actually understand the processes involved!

We are never going to make a dent in reducing carbon emissions while certain world powers & economies are being funded by oil. Ordinary people are being emotionally blackmailed in to reducing their carbon footprint, but this positive action is not being backed up by action from business and government policy.
