So BP says that as much as 100,000 barrels of whatever may be leaking each day...
That's 4 Million gallons...
However..... is this 100,000 barrels only oil or is it other things such as methane as well? Is this 100,000 barrels of (oil + methane + other
gasses)? Or just 100,000 barrels of oil...
The reason this is significant, is because BP has already said
that the mixture coming out is 50% petroleum, and 50% methane and other gasses
Spewing from the ocean floor a mile deep is a mixture that, according to BP, is roughly half methane and other gases by mass and half petroleum
And if this 100,000 barrels only accounts for the oil, then that means that there is another 4 million gallons of methane being released each day AS
If it DOES include the methane, then that's still ~2Million Gallons of Methane being leaked each day... of which 50% of that is making it to the
surface because it's covered with oil, so it will not dissolve as easily in the seawater...
Though BP's guy Valentine says that the methane will dissipate, Scientists who specialize in methane however state that this isn't as true for
methane bubbles covered in oil.. upwards of 50% which starts at the leak will make it to the surface...
So we either have 1 Million gallons of methane or 2 million gallons making it to the surface each day, depending on whether or not the 100,000 barrels
includes the methane or not.
Either way thats A LOT OF METHANE!!!!!!!
Methane is 23 X more potent as a greenhouse gas than CO2
EPA.gov link on methane
Why is there concern about methane emissions?
Methane is 23 times more potent as a greenhouse gas than carbon dioxide (over a 100-year period).
REAL GLOBAL WARMING!!!!!!!
Update: At 100k bpd, about 3.5 X the daily emissions for the entire New York metro area is now reaching the surface.
The following is from a post later on this page, but is relevant to the update...
So when we had 5000 barrels a day as the estimate,
BP said that it was leaking
about 15 million cubic feet of methane each day...
If we look at the EPA units conversion tool
we see that:
1 cubic foot (CF) methane (CH4) = .04246 pounds of CH4
15 million CF CH4 x .04246 = 636,900 pounds CH4 = 318.5 metric tons CH4
318.5 metric tons CH4 = 6,066.9 metric tons CO2 equivalent a day
Now this is still using the 5000 bpd estimate... At this point the total leaked is more than a third of daily CO2 emissions for
the entire New York metro area
But here we are now with an estimate of 100,000 bpd which is 20 X this number which puts us at around 7 X the entire new York metro area...
Now... Half of that is reaching the surface cause it's drenched in oil...
So we basically have had added daily emissions equivalent to the over night appearance of 3.5 X that of the entire new York metro area...
I wonder if that could have a warming effect?
What do you think?
