It shows present day modern temperatures aren't hotter than earlier interglacial period temperatures. And it shows how ridiculous it is to establish a cooler temperature as the reference temperature. Clearly the planet is still within the NORMAL range of the present interglacial period with significantly more atmospheric CO2. And it's BELOW NORMAL for previous interglacial periods. Which is the same thing GISP2 shows.It does NOT show the same thing. That 1997 GISP2 plot is complete shite, even as local data and you repeatedly claimed it was the best possible global data available.
