That's what some new scientific research reported by SoftPedia suggests; that coal is far more damaging in terms of CO2 emissions than is burning petroleum or gas.
"by burning fossil fuel, power plants emit 40 percent more deadly CO2 than facilities using natural gas or crude to generate electricity."
"by using oil and gas alone, humankind may be safe from the effects of global warming for a long time".
So we all have to give up burning coal. Hmmmm, I don't think it is going to be quite that simple, even though the evidence is slowly building up - see TreeHugger.

Just coincidence?
Well, I'll let you judge for yourselves ...... here are a few cards [Explanation later]:-
The Arctic is warming at a faster rate than the rest of the world - Telegraph.
Global coral reefs in seriously bad states - facing mass extinction - SoftPedia.
Global methane levels on the rise again - ABC Science.
More than 2 trillion tons of land ice in Greenland, Antarctica and Alaska have melted since 2003 - ABC News.
2008 has been the coolest year since 2000 (apparently due to La Nina), but the trend still shows warming and it was actually the 10th hottest year on record - Guardian.
I know we've had the coldest early winter for many years here in the UK, and they've had some horrendous ice storms in parts of the USA; but, to use an obtuse little analogy, if you were playing poker and these were your cards, wouldn't you begin to suspect that you'd got the makings of a pretty strong hand?

Ancient technique helps with modern problem
It looks like our forebears knew a thing or two that we seem to have forgotten in modern times.
" Scientists have revealed that an ancient plowing technique can be successfully employed in the fight against global warming and climate change. Burying charred plants into the soil during plowing season virtually stores them indefinitely, while at the same time provides cultures with an abundant source of fertilizers that can maximize production."
The technique buries biochar into the ground, trapping carbon dioxide in the soil for potentially thousands of years; sort of an ancient form of carbon sequestration.
Full story from SoftPediaNews.
My one question is - how much CO2 is released as stuff is partly burnt to produce the biochar?
