snow accumulation, suggest an even more rapid transition, requiring about a 7 °C (13 °F) warming in just a few years.»
In the Bay Area, conditions will not be quite
as favorable
as in the Central Valley, but while precipitation will probably start out
as rain under 2000 feet
snow levels will drop quickly on the back end of the precipitation band associated with the cold front, possibly bringing some
snow accumulations down to 1000 feet and a brief rain /
snow mix to even lower elevations.
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).
The study focused on modeling frost and
snow related land surface processes, such
as frost churning, palsa mires and

Now if you are wondering about Arctic Sea Ice and doubt anecdotal evidence, you could look at Greenland
Snow Accumulation as a proxy of sea ice extent and find that around 1940 there was higher than normal
accumulation, but not quite
as high
as 2012 or circa 1750.
Dansgaard et al. (1989); increasingly abrupt changes were seen on further study, Johnsen et al. (1992); Grootes et al. (1993); jumps of Greenland

as derived from ICESat laser measurements of elevation change
Scientists: Warming causes Antarctic ice sheet growth, and lower sea levels By Kenneth Richard While many scientists are projecting rapid sea level rise
as a result of a warmer Antarctica and consequent ice sheet melting, other scientists are projecting that the surface of the Antarctic ice sheet will gain in mass because a warmer Antarctica means
snow and ice
accumulation will outpace the -LSB-...]
As warmer air can hold more moisture, it is possible that increasing
snow accumulation compensates part of the sea level rise.

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.
Because our existing case law holds that a property owner does not violate the duty of reasonable care by failing to remove natural
accumulations of
snow and ice, see Sullivan v. Brookline, 416 Mass. 825, 827 (1994), the judge concluded that,
as a matter of law, the plaintiff could not prevail on his claims of negligence; therefore, the judge allowed the defendants» motions for summary judgment.
Placing different obligations for
snow removal on different kinds of properties (e.g., businesses and small homes) is entirely sensible and is part of a larger historical trend recognizing that liability for landowners should not hinge on hard - and - fast legal rules (such
as the «natural
accumulation rule») but instead should depend upon the purposes for which the property is used.
The most common causes for ankle injuries in slip and fall cases is
as a result of
snow and ice
accumulation on a poorly maintained surface.
Under what is known
as the «Massachusetts Rule,» a property owner was not liable for failing to remove a natural
accumulation of
snow and ice.
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.»
