Irish chronicles reveal links between cold weather and volcanic eruptions
Medieval chronicles have given researchers a glimpse into the past to assess how historical volcanic eruptions affected the weather in Ireland up to 1500 years ago. Researchers have successfully linked the climatic aftermath of volcanic eruptions to extreme cold weather events in Ireland over a 1200-year period from 431 to 1649.

Two volcanoes erupting in Alaska: Scientists are monitoring and providing alerts on Pavlof and Cleveland volcanoes
Two of Alaska's most active volcanoes -- Pavlof and Cleveland -- are currently erupting. At the time of this post, their activity continues at low levels, but energetic explosions could occur without warning. Located close to the western end of the Alaska Peninsula, Pavlof is one of the most active volcanoes in the Aleutian arc, having erupted more than 40 times since the late 1700's.

Volcanoes cause climate gas concentrations to vary
Trace gases and aerosols are major factors influencing the climate. With the help of highly complex installations, such as MIPAS on board of the ENVISAT satellite, researchers try to better understand the processes in the upper atmosphere. Now, scientists have completed a comprehensive overview of sulfur dioxide measurements.

Landsat thermal sensor lights up from volcano's heat
As the Landsat Data Continuity Mission satellite flew over Indonesia's Flores Sea April 29, it captured an image of Paluweh volcano spewing ash into the air. The satellite's Operational Land Imager detected the white cloud of smoke and ash drifting northwest, over the green forests of the island and the blue waters of the tropical sea. The Thermal Infrared Sensor on LDCM picked up even more.

Canada's distinctive tuya volcanoes reveal glacial, palaeo-climate secrets
Deposits left by the eruption of a subglacial volcano, or tuya, 1.8 million years ago could hold the secret to more accurate palaeo-glacial and climate models, according to new research. The detailed mapping and sampling of the partially eroded Kima' Kho tuya in northern British Columbia, Canada, shows that the ancient regional ice sheet through which the volcano erupted was twice as thick as previously estimated.
