Nature Research Will a changing climate make such events more frequent? The answer? S ee footnote ! Lava flow from Kilauea south of Hawai'i Volcanoes Nat'l. Park. Photo by Ekrem Canli. A paper appearing in Nature today, suggests, t he 2018 eruption of the Kīlauea Volcano in Hawai’i may have been activated by extreme rainfall. The findings indicate that rainfall should be taken into account when assessing volcanic hazards. Rainfall is known to trigger seismic events and can alter volcanic activity. However, observations of such effects are limited to the shallow subsurface of the volcano, and it is unknown whether rainfall can activate deep magma movement. The eruption of the Kīlauea Volcano in Hawai’i was complex and multi-stage, but its trigger has been unknown. From May to August 2018, rifts opened around Kīlauea and the summit exhibited explosive eruptions and caldera collapse. Jamie Farquharson and Falk Amelung examined the impact of rainfall on the 20

Yale ENVIRONMENT 360 Contrails over Manitoba. A PinP photo. New research shows that condensation trails from aircraft exhaust are playing a significant role in global warming. Experts are concerned that efforts to change aviation engine design to reduce CO2 emissions could actually create more contrails and raise daily temperatures even more. Story here.
EcoWatch Extreme floods have become more frequent in the Amazon Basin in just the last two to three decades, according to a new study. More here. Amazon River, Western Para Province, Brazil June 1996. This image shows the flooded condition of a small section of the Amazon River,including the jungle towns of Obidos and Oriximina. The sun’s reflection off of the muddy looking river water, called sun glint or sunglitter, helps to identify land-water boundaries in this section of the Amazon River which is roughly midway between Manaus and the Amazon River Delta. By comparing this image to a detailed map of the area it is obvious that the river is flooding in the low lying areas that are adjacent to the floodplain of the main channel of the river. Large areas south of the main channel of the Amazon River are covered by standing water. Patches of cleared land can be identified within the densely vegetated terrain along the northeast side of the Amazon River. The main c
