@wonderaiapp I started using your app and I’m stunned. I’m wondering about rights. If I create an image, am I allowed to use it anywhere? Do I have the rights to it?

Muscheler: independent tests of IntCal20 by Tephra and floating tree-ring (ice core based timescale by Be10) data show generally good agreement. #INQUADUB19 #intcal #CEZA #C14

[Ronny Friedrich @rfriedr1]

Adolphi: add floating tree rings to #intcal by anchoring them to Be10-based C14. Large effect to calibration of dates around Bølling-Allerød. #INQUADUB19 #C14 #CEZA

Butzin: IntCal20 using modelled marine reservoir ages #INQUADUB19 #intcal #CEZA

[Ronny Friedrich @rfriedr1]

Heaton: Bayesian splines used for IntCal19 for improved treatment of the new data. #INQUADUB19 #intcal #CEZA

[Ronny Friedrich @rfriedr1]

Reimer: New calibration curve expected in 2020 incorporation massive new data from tree rings and other archives. #INQUADUB19 #intcal #CEZA

@OxRadiocarbon Great news. You will surely enjoy the new machine a lot.

T.Schuur at #icdc10: Thawing permafrost accelerates climate change but fossil fuel emissions are by far the main driver.

S.Hammer:14C is great proxy to estimate locally added ffCO2, but corrections needed due to nuclear powerplant&biofuel 14C emissions #icdc10
