Sentences with phrase «more sea ice melting»

In summer more sea ice melts, which leads to decreased albedo, a climate feedback that enhances the warming of both the open ocean water and the atmosphere directly above it.

When parts of the ice melt, liquid water trickles to the base and this can lubricate the underside of the ice sheet, allowing it to slide more quickly into the sea and drive up sea levels at a faster rate.

Pettersen is hopeful that, with more data analysis over longer periods of time, researchers will find more answers yet to account for the melting ice sheet and the subsequent sea level rise that has already had an impact on regions across the planet.

Within a few hundred years sea levels in some places had risen by as much as 10 meters — more than if the ice sheet that still covers Greenland were to melt today.

Given that we now have several years more data, we can essentially «test» the IPCC predictions and we arrive at the conclusion (i.e., message 1) that the climate system is tracking the «worst case scenario» (or worse in the case of ice melt and sea - level rise) presented by the IPCC.

Greenland is more than twice as large as Texas and if the entire ice sheet melted, scientists estimate global sea levels would rise roughly 24 feet.

Melting can be rapid: as the last ice age ended, the disappearance of the ice sheet covering North America increased sea level by more than a metre per century at times.

The impacts of climate change include global warming, rising sea levels, melting glaciers and sea ice as well as more severe weather events.

In recent years, melting sea ice has allowed more of the Pacific water to flow through the Bering Strait into the Arctic Ocean.

A possible cause for the accelerated Arctic warming is the melting of the region's sea ice, which reduces the icy, bright area that can reflect sunlight back out into space, resulting in more solar radiation being absorbed by the dark Arctic waters.

Accumulating data from across the globe reveal a wide array of effects: rapidly melting glaciers, destabilization of major ice sheets, increases in extreme weather, rising sea level, shifts in species ranges, and more.

As climate change warms Greenland and more ice melts and makes its way into the sea, the ice sheet is potentially becoming a more important source of nutrients, he said.

Totten Glacier, the largest glacier in East Antarctica, is being melted from below by warm water that reaches the ice when winds over the ocean are strong — a cause for concern because the glacier holds more than 11 feet of sea level rise and acts as a plug that helps lock in the ice of the East Antarctic Ice Sheice when winds over the ocean are strong — a cause for concern because the glacier holds more than 11 feet of sea level rise and acts as a plug that helps lock in the ice of the East Antarctic Ice Sheice of the East Antarctic Ice SheIce Sheet.

When a glacier melts, it thins, weakens and speeds up, letting more landlocked ice drain into the ocean, causing sea levels to rise.

The shrinking sea ice drives a classic positive feedback loop: as more ice melts, fewer patches of white snow reflect solar energy, and larger regions of dark, sunlight - absorbing seawater open up — both causing the ice to melt even faster.

More comes from melting sea ice, says Laura de Steur of the Royal Netherlands Institute of Sea Research in «t Horntje, who is tracking the build - sea ice, says Laura de Steur of the Royal Netherlands Institute of Sea Research in «t Horntje, who is tracking the build - Sea Research in «t Horntje, who is tracking the build - up.

GRACE showed that the melting polar ice sheets are contributing more to sea level rise than the demise of mountain glaciers.

If all the ice in Greenland were to melt in coming decades (an unlikely scenario), it would raise sea levels by seven meters (more than 20 feet)-- enough to swamp New Orleans, Florida's coast, Bangladesh and the Netherlands, among other low - lying lands.

Rising polar temperatures caused the average thickness of winter Arctic sea ice to decrease from about 12 feet to 6 feet between 1978 and 2008, and thinner ice melts more readily.

Swims are occurring more often, in association with sea ice melting faster and moving farther from shore in the summer.»

The research team, led by Woods Hole Oceanographic Institution (WHOI), suspects that melting sea ice has left more open water near the coast for winds to create waves.

There are more open water leads within the ice, and the surface melt of the sea ice is more intensive than before.

Data published yesterday by scientists at the Jet Propulsion Laboratory (JPL) in Pasadena, California, and colleagues revealed that Earth's ice sheets are melting at a rate that could mean more than 32 centimeters of global sea level rise by 2050.

Not only are ice sheets in Greenland and Antarctica breaking up faster than scientists expected, but more of their melt water is flowing into oceans, he said, which will raise sea levels by 3.3 feet (1 meter) by 2100.

The researchers had expected the ocean to play a bigger role in eroding away the coastline, as it has elsewhere — especially as climate change is causing more Arctic sea ice to melt away, leaving the surface of the water exposed.

Since so much of the ice sheet is grounded underwater, rising sea levels may have the effect of lifting the sheets, allowing more - and increasingly warmer - water underneath it, leading to further bottom melting, more ice shelf disintegration, accelerated glacial flow, and further sea level rise, and so on and on, another vicious cycle.

But it remained unclear exactly which came first: melting ice and warming seas released more CO2 or more CO2 led to melting ice and warming seas.
