Annual Arctic sea ice less reflective than old ice
In the Arctic Ocean, the blanket of permanent sea ice is being progressively replaced by a transient winter cover. In recent years the extent of the northern ocean's ice cover has declined. The summer melt season is starting ...

Geophysicists employ novel method to identify sources of global sea level rise
As the Earth's climate warms, a melting ice sheet produces a distinct and highly non-uniform pattern of sea-level change, with sea level falling close to the melting ice sheet and rising progressively farther away. The pattern ...

Study: Greenland ice sheet may melt completely with 1.6 degrees global warming
The Greenland ice sheet is likely to be more vulnerable to global warming than previously thought. The temperature threshold for melting the ice sheet completely is in the range of 0.8 to 3.2 degrees Celsius ...

Thames flooding isn't rising, long-term records show
Events of the last few decades give the impression that major floods are becoming more common, but looking at the UK's longest-running series of river-level measurements over 60 years or longer shows this ...

A 'melted' moon makes for bad future landing sites
The miniature radio frequency (min-RF) radar instrument aboard the Lunar Reconnaissance Orbiter (LRO) is revealing some interesting things about how impact melts form around craters on the Moon. Impacts produce ...

Americans' knowledge of polar regions up, but not their concern
Americans' knowledge of facts about the polar regions of the globe has increased since 2006, but this increase in knowledge has not translated into more concern about changing polar environments, according to new research ...

Cold winters caused by warmer summers, research suggests
Scientists have offered up a convincing explanation for the harsh winters recently experienced in the Northern Hemisphere; increasing temperatures and melting ice in the Arctic regions creating more snowfall in the autumn ...

Long-lost Lake Agassiz offers clues to climate change
Not long ago, geologically speaking, a now-vanished lake covered a huge expanse of today's Canadian prairie. As big as Hudson Bay, the lake was fed by melting glaciers as they receded at the end of the last ice age. At its ...

Melting
Melting, or fusion, is a physical process that results in the phase change of a substance from a solid to a liquid. The internal energy of a substance is increased, typically by the application of heat or pressure, resulting in a rise of its temperature to the melting point, at which the rigid ordering of molecular entities in the solid breaks down to a less-ordered state and the solid liquefies. An object that has melted completely is molten. Substances in the molten state generally have reduced viscosity with elevated temperature; an exception to this maxim is the element sulfur, whose viscosity increases with higher temperatures in its molten state.
Some organic compounds melt through mesophases, states of partial order between solid and liquid.
