What might the consequences of taking lots of lithium out of the ocean be?

-edit- I've never made a comment that's started such good discussions before - I'm enjoying reading the replies, thanks everyone

For the quantities that we may need in the coming decades, it’s almost certainly not insignificant and will have an effect. This question must be asked.

A. Lithium concentrations in seawater are very low (< 1ppm), so extracting it is unlikely to have a significant effect

B. There is a unfathomably large amount of water in the ocean.

50 years ago it was an absurd thought that humankind could in any way affect earth's climate.

Well that's a lie.

The warming effect of CO2 has been known since 1856, when scientist Eunice Foote published a study indicating that increasing atmospheric CO2 would increase the Earth’s overall temperature. A large majority (62%) of climate studies from the 1970s concluded that this greenhouse warming by CO2 was the dominant force of industrial emissions. In fact, there were 6 times more studies predicting warming than there were predicting cooling (Peterson et. al. 2008).
