Anyone who still believes that global warming is just a hoax needs to do some serious researching, or better yet, take a walk outside. Are you from this planet or have you been in a hole for the past 15 years? I work with children; there are countless days in the summer when we are not allowed to take the children outside because the "air quality is poor and too hot". Being from New Jersey, USA, I remember my parents talking about the winters of the 50's and 60's from their childhood. It would start snowing in late November and green grass would not be seen until the "thaw" in the spring. Last year I went rollerblading in February on a freakish warm day in shorts and a T-shirt and I think we got about 4 good snowfalls, but that number could be less. Is the earth warming up? Yeah. I think so. Have some common sense.
Oh, and I agree with Silvia 100%. WAKE UP! Stop living in the world of fantasy!

Economics is the key to solving global warming challenges. Anthropogenic GHG emissions should be reduced by using government’s enormous existing revenue requirements to discourage, rather than encourage, GHG emissions and deforestation. Gradually shifting the majority of the tax burden away from labor and industry, and towards both the initial and ongoing cost of GHG-intensive practices (at the point of sale) will increase low-GHG practices as they become more cost-effective. Economies of scale will improve the viability of low-GHG technology. Companies and communities that take advantage of society’s inevitable needs will enjoy a tremendous technological and marketing advantage. Congestion, pollution, infrastructure, trade deficits and real energy costs will decrease. And, most importantly, the cost and problems associated with global warming will perhaps be avoided.

Global warming is real and I am an American who believes that something should be done about it. To counter argue your point about the Europeans not having a real leader since Churchill, honestly, we haven't had a great president since JFK. What happened to honesty? What happened to a the idea of a government for the people, by the people. We have all these high on the hog polticians who are only politicians. When America was great the politicians were the best and brightest of our citizens but now we have these wishy washy generational senators, congressman, and presidents. We need a fresh start and more politicans who arent on the take from every special interest group out there. Its sad but I'm not nearly as proud to be an American as I ought to be. I love basball, football, rock and roll, the girls in the southern half of the us but I can not stand what is being done with my country. I should be able to love it so much more. There is nothing socialist about wanting clean air!

Shaun, Olathe, kansas,

Not all of us Americans are as ignorant as the guy from Orlando Florida. I am very dissapointed in our government here and in fact we haven't had a good leader in quite some time. Too much longer with this administration's single minded policies and we will all go to Hell in a handbasket!

Delores Forbes, Spring Lake, US / NC

I can`t believe there are still such inviromental-ignorant people. Who will care for economy when the only place we have to live in is fading away?! This comment is so typical of a US citizen, you are in your ¨untouchable perfect¨ bubble, WAKE UP.
Research, investigate, then you can submit an opinion don´t just repeat what your government tells you and wants you to believe! LOOK OUTSIDE THE US AND EUROPE.
Global warming is a reality, wether you want to see it or prefer to ingnore it even with all the hard evidence around us.
What kind of leader do you follow?

Silvia, San Jose, Costa Rica

Yes, you Europeans are such leaders. Please...hasn't been a real leader since Churchill. This global warming hysteria is just another excuse for the socialists to try to control how everyone lives, just as the predicted new ice age was in the 1970s. And you "European leaders" fall for it hook, line, and sinker. But I suspect your so-called "leaders" know it's a bunch of hog wash, but that all you sheeple in Europe will blindly follow. And as for Kyoto, it would devastate economies around the world and wouldn't make one bit of difference even if there was something to the global warming hysteria.

James Ryder, Orlando, Florida, USA

I'll say! It's certainly positive. I also agree with Laurence, it's power to the people! Spread the eco-warrior enthusiasm for the world!!!

Actually, I agree with you too David!

Mikael, Cardiff,

re your picture of the great and the good at G8. I cannot help thinking Angela does a great Eric Morecanbe impression.

How many ways can one say 'you people have lost touch'.The good news is that the focal length of a Politician is the next election.

Desmond Taylor, Houston, USA Texas

Lets hope this promise doesn't become partialy hollow like the one 2 years back. Most of the nations are behind in the aid they vowed to give, which is a great dissapointment. The electorate need to make their leaders more accountable on what they agree to when it comes to the great ethical issues of our age such as poverty and climate change. But thankfully Britain is leading the way since Gleneagles, and may we do that one again this time.

Laurence, Lincoln, UK

The Americans always want to be at the forefront of any initiative as being the "instigator". It goes against their ego to agree with us (Europeans) and be a follower.

Bush has been meeting with all the US Automotive CEO's over the last month, attempting to get commiments on emissions.

You watch they (USA) will come out with something that seems different, but is the Kyoto in another form.

David Lewis, Benfleet, Essex

Best news in months!
