Deep Ice

09/05/2006 8:27 AM

The European Project for Ice Coring in Antarctica (Epica) has just completed a 3.2 km deep ice core extraction in east Antarctica. This enables sampling of the atmosphere over the last 800 thousand years.

The scary thing is the rate of change of CO2 in the core. Never in the past 800 thousand years it exceeded 30 parts per million (ppm) by volume in a thousand years. That is, except for in the last century.

"The last 30 ppm of increase has occurred in just 17 years", said Dr Eric Wolff from the British Antarctic Survey (BAS). That is over 50 times faster than ever before. Read more on BBC News.

The good news

09/05/2006 10:50 AM

Is that the majority of the man-made CO2 emissions comes from the burning of fossil fuels with the remainder coming from slash and burn farming. Fossil fuels are a limited resource and soon wont be able to provide for our ever growing energy needs. In other words, our own greed will force us to develope a better method of generating energy. As none of the current alternatives lead to CO2 emmissions (fission, fusion, solar, etc.), we should be alright. Of course the temperature of the planet will be higher by then, but hopefully not substantially higher.

Re:The good news- is bad news also

Too much of CO2 sure will change the atmosphere for a while and next 100 years will be badly affected.

Perhaps, this excess CO2 will be eaten away by forest trees if they are not disturbed. This is the only natural way to keep the CO2 in limit.

For nature, there is a way to show its anger, when limits are crossed. You can have endless fun in nature destruction.

CO2 is a good thing!

09/08/2006 3:14 PM

Try reading the massive data at www.co2science.com and realize that co2 is a good thing, and that we should thank people who drive SUVs for making co2. Wild fires and natural burning creates many bad things, such as soot, NOx and co, whereas a good running engine burns the fuel into co2 and h2o. We should tripple co2 concentration, not lower them. CO2 has next to no effect on warming, according to the data. I find it funny that nobody would hire an engineer who made a computer model to simulate a process when he gets the wrong answers consistantly, but when politics get involved, these same failing engineer are listened to and considered experts, when they clearly have no clue, according to the data. Try getting the climate models to match real world data. If you can't, you don't have a model, you have fiction. The facts show we want more co2, not less, especially if the solar cycle is increasing. Read co2science.com and get the facts straight. Turn your brain on...
