On the possibility of phase transitions with the formation of SiO2 peroxide forms in the earth mantle and their effect on mantle convection
Based on the hypothesis advanced by S. P. Gabuda that the SiO2 molecule could undergo a transition from the linear form to the isomeric form with a ring-shaped (bent) structure, an idea is proposed that when the mantle ...
Reply to 'Limited Late Antique cooling'
We discuss the combined efficacy of environmental, archaeological and historical indicators in establishing a prolonged period of cold summers across much of the Northern Hemisphere landmass between 536 and about 660 AD, ...
Climate response to the Samalas volcanic eruption in 1257 revealed by proxy records
The eruption of Samalas in Indonesia in 1257 ranks among the largest sulphur-rich eruptions of the Common Era with sulphur deposition in ice cores reaching twice the volume of the Tambora eruption in 1815). Sedimentological ...
Tree rings reveal globally coherent signature of cosmogenic radiocarbon events in 774 and 993 CE
Though tree-ring chronologies are annually resolved, their dating has never been independently validated at the global scale. Moreover, it is unknown if atmospheric radiocarbon enrichment events of cosmogenic origin leave ...
Siberian tree-ring and stable isotope proxies as indicators of temperature and moisture changes after major stratospheric volcanic eruptions
Stratospheric volcanic eruptions have far-reaching impacts on global climate and society. Tree rings can provide valuable climatic information on these impacts across different spatial and temporal scales. To detect ...
Limited capacity of tree growth to mitigate the global greenhouse effect under predicted warming
It is generally accepted that animal heartbeat and lifespan are often inversely correlated, however, the relationship between productivity and longevity has not yet been described for trees growing under industrial and ...
