Warm summers in the Younger Dryas?
The Younger Dryas was a period (12,900–11,600 BP) towards the end of the last glaciation when glaciers re-advanced in Scotland and the tundra plants, including the eponymous Dryas, replaced the Bølling-Allerød forests in Denmark. These changes indicate the Younger Dryas was … Continue reading

From the Journal of Younger Dryas Impact Hypothesis Studies
The Journal of Younger Dryas Impact Hypothesis Studies (formerly the prestigious journal known as the Proceedings of the National Academy of Sciences; PNAS) has just published Kennett et al, yet another paper promoting the hypothesis that the Younger Dryas, mass extinction … Continue reading
Yet another Younger Dryas impact paper
Just when you thought that Holliday et al (2014) had dealt the Younger Dryas impact hypothesis a mortal blow, along comes another paper proclaiming that the hypothesis lives yet. Kinzie et al (2014) claim that nanodiamonds are indicators of cosmic impacts and look at … Continue reading

PNAS is a high impact journal
Another month, another paper enthusiastically discussing the thin evidence for a extra-terrestrial impact at the start of the Younger Dryas is published in PNAS. Wu et al (2013) report osmium isotope ratios from putative Younger Dryas boundary layers at various … Continue reading

Platinum spikes extra-terrestrial impact as initiator of Younger Dryas
Decades passed between the first suggestion that the mass extinction at the Cretaceous-Palaeogene boundary was caused by an extra-terrestrial impact, and this hypothesis becoming accepted by most geologists as evidence — the global iridium anomaly, shocked quartz grains and tektite … Continue reading
