Could rising sea levels put us in danger of that lurking menace, "Red Tide?"

A good question is over the manners in which these geo-engineered climate changes (of which iron fertalization is just one form) affects life:

If there is no significant long term warming of the Earth and people instead pressure for reducing the temperature, how would that affect what a next Ice Age might look like? (Especially if those changes are of a semi-permanent form, like some suggestions of solar reflectors in space to block the Sun?)



Here's a chart of how estimated levels of CO2 have dropped over time on Earth as carbon is continually sequestered:



Here's a graph showing the rate of plant growth versus levels of CO2:



So, another question is if CO2 levels are to be reduced, to what extent does that decrease vegetation and life on Earth in association with those lost aspects of the carbon cycle and is there a point below which a loss of CO2 could even be effectively lethal for life on Earth?

Any additions of CO2 to the atmosphere are temporary and the trend is naturally downward because CO2 is chemically active. There's actually a minimum level below which plant life can't survive and little evidence, despite the propaganda, that the benefits of higher levels of CO2 have much of any harmful tradeoffs.

And something else "they" seem to conveniently fail to mention is that the greenhouse effect of CO2 is related to the logarithm if the density of CO2 in the atmosphere (ignoring displacement of other greenhouse gases), which means that for any significant change in temperatures directly related to CO2 to occur would require it be reduced to practically 0 ... at which point, there'd likely be no prospect of life on Earth to worry about protecting:

I seem to remember that the sea has turned red and bluish on occasions apparently due to an over abundance of plankton,whether this has anything to do with global warming I know not.

Not sure we are speaking about the same globe.

Maybe the earth is dying?

I am very sure mate,are you?
