[1] Understanding natural causes of climate change is vital to evaluate the relative impacts of human pollution and land surface modification on climate. We have investigated one of the most important natural causes of climate change, volcanic eruptions, by using 54 ice core records from both the Arctic and Antarctica. Our recently collected suite of ice(More)
OBJECTIVES Glioblastoma (GB) is the most common, aggressive, and proliferative among all brain tumors. The prognosis of GB is still far from satisfactory currently, thus demanding great modification and enhancement, which may be acquired by the help of the molecular target therapy. Nuclear factor E2-related factor 2 (Nrf2), a pivotal transcriptional factor(More)
[1] We combined 33 ice core records, 13 from the Northern Hemisphere and 20 from the Southern Hemisphere, to determine the timing and magnitude of the great Kuwae eruption in the mid-15th century. We extracted volcanic deposition signals by applying a highpass loess filter to the time series and examining peaks that exceed twice the 31 year running median(More)
The response of the El Niño/Southern Oscillation (ENSO) to tropical volcanic eruptions has important worldwide implications, but remains poorly constrained. Paleoclimate records suggest an "El Niño-like" warming 1 year following major eruptions [Adams JB, Mann ME, Ammann CM (2003) Nature 426:274-278] and "La Niña-like" cooling within the eruption year [Li(More)
