The Financial Times advises us to Follow the science. It's a pity that they didn't follow their own advice.
They claim: "...especially in the Arctic, where summer sea ice has shrunk alarmingly over the past five years." oh, really - follow the science:

The FT says: The geological record shows that natural change can happen extremely fast.."
Well, the 650,000 years of Vostok Ice core samples show that warming causes atmospheric Co2 to rise with a lag of 800=/-200 years. The Medieval Warm Period was approximately 800 years ago.
The FT says: (Climatologists) suggest a real (though probably small) risk that, by pumping carbon dioxide in the atmosphere to levels not seen for millions of years, we could trigger catastrophic, runaway global warming.
Hello!?! Look at the Vostok Ice Core samples - CO2 does not cause warming. And as for millions of years, well, it's a bit shorter than that. FT should follow the science. The determination of atmospheric CO2 by the Pettenkofer method shows levels around 450 ppmv at c1820 and c1948.
FT should examine the science before it exhorts others to "follow the science."
