Well the best way is to decrease the amount of CO2 emission and to decrease the emission of acidic compounds.

You can fight the symptoms of coral bleaching by either mixing cold with hot water in the oceans to cool the water, so that the algea (zoöxanthelle) that give coral color have a better habitat. Australia is investing 2.2 billion in big mixers. Decreasing wastewater and chemical waste dumps in oceans in feneral also makes the habit better for Corals and the Algea, so that wouldn't hurt either.

Adding more calcium to the water also works, since calciumcarbonate increases the pH, but you would need the entire coast of dover multiple times. So cutting fossil fuels is really the best way we have.

That's what I thought. Kill the fossil fuels! ^^

And speaking of algae plumes, could we harvest the algae as a fuel source? I've heard of it being done.

You can win bio oil from Algae, from which you can make plastics, fuels and other carbohydrates. Some algae also produce hydrogen under some circumstances.

In theory you could use over fertilised water around farms to grow algae in. The algea use the nutrients and using a biorefinery you can win the nutrients back and other compounds like bio oil back. The  clean defertilised water, could be injected into the local water system, making that cleaner as a result.

He pretty much explains why earth is a long way from runaway greenhouse warming like Venus is and also explains the benefit that CO2 emissions bring in such as higher crop yields so I guess ~1000 ppm of CO2 is ideal for plant life ... (need to at least double the CO2 concentration)

Does he account for the impact higher temperatures might have on crop yields as well as effect on water supplies?

An independent research shows that plants prefer warmer temperatures too and according to Gardner's Supply Company's data most crops can handle a temperature of up to 35 degrees Celsius ...

As far as water supply goes, NASA has shown that Earth overall is greening so there is most likely no discernible negative effect either on soil moisture ... 

We could use that land from Canada, Northern Europe and Russia so that we could feed more people AND feed them more desirable crops too while we're at it! C'mon, we could end world hunger a whole lot sooner if we raised temperatures and CO2 concentrations just a bit ...
