"And all that extra aerosol matters, of course, because aerosols seed clouds, which change the weather."

"The science is settled, except we only just realised that the benzene and toluene gas over the vast Southern Ocean were not man-made pollutants after all, but were made by industrious phytoplankton. For the first time someone went and measured the benzene and toluene in the water and discovered that, instead of being a sink for human pollutants in the air above, the ocean was the source.
    "This matters because these two gases increased the amount of organic aerosols by, wait for it, between 8% and up to 80%, in bursts. And all that extra aerosol matters, of course, because aerosols seed clouds, which change the weather.
    "And the expert climate models, upon which a $1.5 Trillion dollar industry depends on for its very existence, did not know this. If hypothetically there has been less phytoplankton in the worlds oceans in the last few decades, there may also have been less cloud cover, and thus more warming. But who knows?
    "The modellers are always saying climate change can’t be natural because they can’t think of anything else that could have could have caused the warming, then people keep finding another factor they forgot to put in the models…"
