Global mean sea level rise estimated from satellite altimetry provides a strong constraint on climate variability and change and is expected to accelerate as the rates of both ocean warming and cryospheric mass loss increase over time. In stark contrast to this expectation however, current altimeter products show the rate of sea level rise to have decreased from the first to second decades of the altimeter era.

The Sakurajima volcano in Kyushu Japan had an explosive eruption early Tuesday, spewing volcanic ash 5,000 meters into the sky, the Japan Meteorological Agency said.

This paper presents the findings from a study aimed at understanding whether video games (or serious games) can be effective in enhancing volcanic hazard education and communication. Using the eastern Caribbean island of St. Vincent, we have developed a video game – St. Vincent's Volcano – for use in existing volcano education and outreach sessions. Its twin aims are to improve residents' knowledge of potential future eruptive hazards (ash fall, pyroclastic flows and lahars) and to integrate traditional methods of education in a more interactive manner.

The rate of global mean surface temperature (GMST) warming has slowed this century despite the increasing concentrations of greenhouse gases. Climate model experiments show that this slowdown was largely driven by a negative phase of the Pacific Decadal Oscillation (PDO), with a smaller external contribution from solar variability, and volcanic and anthropogenic aerosols . The prevailing view is that this negative PDO occurred through internal variability.

Italy's Mount Etna, Europe's highest and most active volcano, has once again erupted, spewing red torrents of lava into the sky.

VIENNA – Natural disasters have caused more than $7 trillion in economic damage worldwide since 1900, with floods and storms accounting for nearly 60 percent of the total, researchers said Monday.

A volcano on the Alaska Peninsula erupted with little advanced warning over the weekend, spewing an ash cloud up to 20,000 feet (6,096 meters) high that prompted aviation warnings across the region

Pavlof Volcano, located on the Aleutian Islands, is one of the most active in the region.

A volcano in the Alaskan Aleutian Islands erupted on Sunday afternoon, sending ashes to 20,000 feet in the air. The U.S.

Volcanoes are primed to erupt on a time scale of days to months rather than years, research suggests.
