For example, in Christmas of 1995, Boston received snow and the following year, the S&P 500 increased by more than 20 %.

More worryingly, the actual increase in rain, snow and sleet were larger than predicted by the computer models.

The sport mode that comes with this model allows for better performance in snow and ice than expected, and is very useful for interstate on ramps where speed increase is important.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

In Cohen et al. 2009, we showed a statistically significant link between increasing snow cover extent in Siberia and colder Northern Hemisphere temperatures, so there is more to my article than thinking out loud.

For the entire Northern Hemisphere, there is evidence of an increase in both storm frequency and intensity during the cold season since 1950,1 with storm tracks having shifted slightly towards the poles.2, 3 Extremely heavy snowstorms increased in number during the last century in northern and eastern parts of the United States, but have been less frequent since 2000.11,15 Total seasonal snowfall has generally decreased in southern and some western areas, 16 increased in the northern Great Plains and Great Lakes region, 16,17 and not changed in other areas, such as the Sierra Nevada, although snow is melting earlier in the year and more precipitation is falling as rain versus snow.18 Very snowy winters have generally been decreasing in frequency in most regions over the last 10 to 20 years, although the Northeast has been seeing a normal number of such winters.19 Heavier - than - normal snowfalls recently observed in the Midwest and Northeast U.S. in some years, with little snow in other years, are consistent with indications of increased blocking (a large scale pressure pattern with little or no movement) of the wintertime circulation of the Northern Hemisphere.5 However, conclusions about trends in blocking have been found to depend on the method of analysis, 6 so the assessment and attribution of trends in blocking remains an active research area.

Furthermore, slightly warmer than normal temperatures increase atmospheric moisture content, elevating potential snow amounts where they occur.»

Whether it's a killer winter in South America, increased snow cover globally, record Arctic sea ice recovery, recovering glaciers in the Alps, record high sea ice extent in Antarctica, extreme cold in southeast Europe, or 5 consecutive colder than normal European winters, just to name a few, the ominous signs of global cooling are compounding rapidly.

Furthermore, the Arctic has warmed more than twice as fast as the global average, a phenomenon known as Arctic amplification, and stimulated by the combined increasing Arctic temperatures and rapid loss of sea ice in all seasons along with declining snow cover in the spring and early summer.

But rather than snow depth to actually increase snow cover, the winds will have to carry that extra snow down south...

If warming continues, and snow increases during winters, locking up more moisture regionally until spring or summer floods release the reservoir with more energy and intensity in those snow - pack zones (while former recipients of rain go wanting in drought) than in prior regimes?

More than one - sixth of the world's population live in glacier - or snowmelt - fed river basins and will be affected by the seasonal shift in streamflow, an increase in the ratio of winter to annual flows, and possibly the reduction in low flows caused by decreased glacier extent or snow water storage (high confidence)[3.4.1, 3.4.3].

Although increased vegetation would sequester additional carbon, this would be more - than - offset by the loss of the albedo effect, whereby sunlight bounces off white (snow and ice covered) parts of the Earth.

Thawing permafrost also delivers organic - rich soils to lake bottoms, where decomposition in the absence of oxygen releases additional methane.116 Extensive wildfires also release carbon that contributes to climate warming.107, 117,118 The capacity of the Yukon River Basin in Alaska and adjacent Canada to store carbon has been substantially weakened since the 1960s by the combination of warming and thawing of permafrost and by increased wildfire.119 Expansion of tall shrubs and trees into tundra makes the surface darker and rougher, increasing absorption of the sun's energy and further contributing to warming.120 This warming is likely stronger than the potential cooling effects of increased carbon dioxide uptake associated with tree and shrub expansion.121 The shorter snow - covered seasons in Alaska further increase energy absorption by the land surface, an effect only slightly offset by the reduced energy absorption of highly reflective post-fire snow - covered landscapes.121 This spectrum of changes in Alaskan and other high - latitude terrestrial ecosystems jeopardizes efforts by society to use ecosystem carbon management to offset fossil fuel emissions.94, 95,96

Polar bears are one of the most sensitive Arctic marine mammals to climate warming because they spend most of their lives on sea ice.35 Declining sea ice in northern Alaska is associated with smaller bears, probably because of less successful hunting of seals, which are themselves ice - dependent and so are projected to decline with diminishing ice and snow cover.36, 37,38,39 Although bears can give birth to cubs on sea ice, increasing numbers of female bears now come ashore in Alaska in the summer and fall40 and den on land.41 In Hudson Bay, Canada, the most studied population in the Arctic, sea ice is now absent for three weeks longer than just a few decades ago, resulting in less body fat, reduced survival of both the youngest and oldest bears, 42 and a population now estimated to be in decline43 and projected to be in jeopardy.44 Similar polar bear population declines are projected for the Beaufort Sea region.45

In my experience that's usually the biggest variable, but there could be many reasons for your results to vary — puddling resulting in increased splashing on one side or another, snow removal activities or pavement salting that occurred unbeknownst to you, albedo alterations due to dirt that preferentially affect one area more than another, and so on.

In some regions where winter precipitation is projected to increase, the increased snowfall can more than make up for the shorter snow season and yield increased snow accumulation.

The retreat has been most noticeable at high elevations, driven in large part by warming temperatures contributing directly to melting and indirectly to more precipitation falling as rain rather than snow, in turn increasing the rate at which the glaciers move and increasing the size of glacial lakes, both decreasing ice cover.

-- First we increase the greenhouse gases — then that causes warming in the atmosphere and oceans — as the oceans warm up, they evaporate more H2O — more moisture in the air means more precipitation (rain, snow)-- the southern hemisphere is essentially lots of water and a really big ice cube in the middle called Antarctica — land ice is different than sea ice — climate models indicated that more snowfall would cause increases in the frozen H2O — climate models indicated that there would be initial increases in sea ice extent — observations confirm the indications and expectations that precipitation is increasing, calving rates are accelerating and sea ice extent is increasing.

The combination of the warming with increased greenhouse gases and the increased precipitation falling as rain rather than snow is a double whammy for the region.

: — RRB - statistically rather than logically it is possible for a record to be set without it indicating that the process involved (northern hemisphere «winter» snow generation) has increased its average output.

We saw an increase in total precipitation falling as rain rather than snow.
