Sentences with phrase «ice accumulations which»

Consequently winter snows and ice accumulations which were formerly melted in summer are no longer dissipated.

Not exact matches

David Ullman, a postdoctoral researcher at Oregon State University and lead author on the study, said there are two mechanisms through which ice sheets diminish — dynamically, from the jettisoning of icebergs at the fringes, or by a negative «surface mass balance,» which compares the amount of snow accumulation relative to melting.

Snow accumulation builds up the ice sheet, but the extra flakes have not acted as a life raft for West Antarctica's ice sheet, which previous research has found is rapidly thinning as the climate warms, Thomas said.

Researchers have attributed glacial decline to increasing temperatures, which have reduced the period of glacial accumulation and extended the period of summer ice melting (ablation).

Many of the studies which demonstrate the effectiveness of ice baths in reducing inflammation and accumulation of white blood cells (the guys responsible for destroying damaged tissue and creating signals for re-growth) measure this response over a very short time frame - for hours or a couple of days at best.

Back - of - the - envelope calculations show that the latent heat absorbed by melting of ice after surges (e.g., the melting of > 1500 years of ice accumulation during Dansgaard - Oeschger events — which seem to have happened in unison across the northern hemisphere, or the longer > 5ky Bond cycles) can significantly contribute to the global energy balance.

And it means more time must be spent on those ice sheets, both in the melt zones and the places where accumulation of snow still dominates — including Swiss Camp, which I visited on the flanks of the ice sheet in 2004:

The acceleration increased the mass loss from 5 km3 ice / year in 1996 (12) to 36 km ice / year in 2005 (Table 1), which is 6 % of Greenland's total accumulation.

In outline, the model supposes that the rate of change of ice extent has two terms - accumulation proportional to its length, and loss at the grounding line which is proportional to the cross-section area there, which because a constant width is assumed is proportional to the depth of the ice.

Therefore, the processes of accumulation and ablation are the physical link between glaciers and climate, which explains why these ice bodies are such valuable tracers of climate variability on the scale of decades and centuries.

This snowpack accumulation near the poles, which gets its water via the Arctic and Antarctic oceans, that in turn rob it from equatorial latitudes of our oceans, also results in a reduction in the earth's spin axis moment of inertia and causes the spin rate to increase as evidenced in the recent history of the rate at which Leap Seconds are added to our calendar (see Wysmuller's Toucan Equation for more on this evidence that during this warm time with much greater polar humidity, earlier seasonal, later seasonal and heavier snows are beginning to move water vapor from the oceans to the poles to re-build the polar ice caps and lead us into a global cooling, while man - made CO2 continues to increase http://www.colderside.com/faq.htm).

Stomata data are in no way «better» than ice core CO2 data, they are proxy's of local CO2 levels, not like ice cores which are direct measurements of CO2 in the ancient bulk (95 %) of the atmosphere, be it averaged over several years to several centuries, depending of the snow accumulation rate of the ice core.

These rapid changes are the result of increased discharge from grounded ice into the ocean and from increased ice melting, which more than outweigh increases in surface accumulation.

And ice motion is caused by gravity (the slope of canyons which channel the ice off the continent) and basal melting from trapped accumulations of geothermal heat, correct?

That all changed with the Supreme Judicial Court's 2010 decision, Papadopoulos v. Target Corp., in which the court abolished any legal distinction between natural and unnatural accumulations of snow and instead said that a property owner has a duty to act «as a reasonable person under all the circumstances» with regard to removal of snow and ice.

What if a property owner shovels snow which then results in an unnatural accumulation of ice that causes an injury?

Where the obstruction was snow or ice on stairs or a walkway, a landlord could be held liable to the tenant only if he placed the snow or ice there, or was otherwise responsible for it being there, which he would not be if the snow and ice were a natural accumulation.

This court abolished, in premises liability actions involving a slip and fall on snow and ice, the distinction between natural and unnatural accumulations of snow and ice, which had constituted an exception to the general rule of premises liability that a property owner owes a duty to all lawful visitors to use reasonable care to maintain its property in a reasonably safe condition in view of all the circumstances [370 - 384]; further, this court saw no reason to limit its holding to prospective application [384 - 386].

This rule, as we apply it, provides that a landlord or business invitor owes aduty to a tenant or business invitee 1292 * 1292 «to use reasonable care to see that the common areas are kept reasonably safe from the dangers created by an accumulation of snow and ice which is attributed to purely natural causes.»

The Supreme Judicial Court granted further appellate review, and, after reviewing the law in this area over the last century, the Court concluded that the distinction between natural and unnatural accumulations of snow and ice was a «relic of abandoned landlord - tenant law» which «has sown confusion and conflict in our case law.»
