Thursday will be the second October 10th in a row with record cold here in Boulder, Colorado. We have about five inches of snow in the forecast. It will also be a record for earliest day to not get above freezing – the previous record being October 11, 2009.
And the trend has been sharply downwards since CO2 hit 350 PPM.
But for climate scientists at NCAR, it will be just another day of looking at climate models – instead of out their window.
This is how I spent the first day of summer this year in the mountains above Boulder.
