The Neo Paleo Twitter war of Mann -vs- D’Arrigo

It seems that Columbia’s Rosanne D’Arrigo thinks Mann’s tree ring study isn’t representative proxies for volcanic eruptions, nor good for dendrochronology, though Mike Mann seems to think so. This Twitter interchange via Alexandra Witze from the AGU Chapman Conference on … Continue reading

Solar grand minima linked to cooling period in Europe

This is interesting. A quick cooling in Europe together with an increase in humidity and particularly in windiness was found to coincide with a long-term reduction in solar activity 2800 years ago during something called the “Homeric minimum”. The paper … Continue reading

Mann: Trees aren’t behaving like I want them to – volcanoes to blame

From Penn State Tree rings may underestimate climate response to volcanic eruptions Some climate cooling caused by past volcanic eruptions may not be evident in tree-ring reconstructions of temperature change because large enough temperature drops lead to greatly shortened or … Continue reading
