A New Global Warming Worry?
We all know carbon dioxide, a naturally occurring chemical - the product of the respiration of every animal on earth - which is also produced by the burning of fossil fuels such as oil, coal and natural gas. And some of us may have also heard about methane, another of the greenhouse gases, which may also have a significant role in global warming over the next few decades (I'll post more on methane another day - it gives me a headache). But today from Japan comes a report on yet another greenhouse gas. Dinitrogen oxide, which originates from nitrogen-based fertilizers used on farms. The chemical was measured through the use of ice cores taken from Antarctica and has been increasing slowly for the past 50+ years.

There are noble gasses, but I'm not so sure about 'greenhouse' gasses. I agree the earth is warming, but I disagree 'greenhouse gas' is the cause. The sun affects the earth much more than 'greenhouse gas' and we are in a period of high sunspot activity. If sunspot activity dies down a bit, say in the next 50 years, and a mini-ice age begins, we might welcome our 'greenhouse'.

We are all worried about this global warming. It's great that you started a blog about it. I think the two biggest questions on the subject would be:
1) If human beings were extinct and not affecting climate change, would the climate still change?
2) What should the global temperature be? What is the ideal temperature? Should it ever change?
Thanks!

Anyone who is concerned about global warming -- and we all should be -- needs to get out tomorrow and vote Democratic. Bush has caused the increasing destruction of the planet and the ecosphere in which we all live for six years now. Let's hope it isn't too late.

I can't believe so many people think Global Warming is effecting our weather. People think if it gets up to 100 Degrees for one day they think Global Warming is the cause of it and global warming doesn't do things like this or people thought global warming was the cause of so may hurricanes last year, if that was the case why aren't we having hurricanes this year. All these weather phenomons are part of a cycle or El Nino. If you ever look at past weather records you will notice that the weather will be bad for two years and then calm down, it's just due to El Nino or a cycle.

it is sign of the times no such thing as global warming. God make earth and everthing that in it and God have no forgot it.

Why do I always detect a tendency for global warming alarmists to emphasize mankind's less than 2% contribution to CO2 emissions while deemphasizing nature's greater than 98% contribution to CO2 emissions through plant decay, volcanic eruptions, and forest fires of the lightning caused type?
