Not exact matches

An increase in snowfall has long been predicted as a result of global warming.

The greatest increase in snowfall has been over the Antarctic Peninsula, where the mass of snow per decade has risen by 123 gigatonnes in 200 years.

After further analysis of the data, the scientists found that although a strong El Niño changes wind patterns in West Antarctica in a way that promotes flow of warm ocean waters towards the ice shelves to increase melting from below, it also increases snowfall particularly along the Amundsen Sea sector.

The study also suggests that the accelerated melting of mountain glaciers in recent decades may explain a phenomenon that has long puzzled scientists — why Arctic and sub-Arctic rivers have increased their water flow during the winter even without a correlative increase in rain or snowfall.

Planes lifting off through a specific kind of cloud cover can inadvertently increase snowfall below

Warmer winters combined with an increase in snowfall during the last 30 years have limited the growth of seasonal lake ice.

For the first time, scientists have obtained direct, quantifiable observations of cloud seeding for increased snowfall — from the growth of ice crystals, through the processes that occur in clouds, to the eventual snowfall.

In 2008 a satellite study based on rates of snowfall and ice movement estimated a loss of 210 cubic kilometers of ice per year — a 59 percent increase in the past decade.

This sets up a competition of sorts between higher snowfall, which increases the Arctic ice cover, and the higher temperatures that melt it.

Contrary to what you might expect, the third IPPC report predicted that global warming would most likely lead to a thickening of the ice sheet over the next century, with increased snowfall compensating for any melting cause by warming.

They are part of SNOWIE, an NSF - funded project to study whether cloud seeding increases snowfall.

«Thus the increased snowfall we report here has not led to thickening of the ice sheet, but is in fact another symptom of the changes that are driving contemporary ice sheet loss.»

Local officials claim this is proof that the government's environmental preservation efforts have been successful, but recent research by climate scientists suggests a more worrying explanation for rising water levels: not only is climate change thought to be responsible for increased rainfall and snowfall in the area, it has also caused, by some estimates, up to a fifth of the permafrost which covers 80 % of the plateau to melt.

Previous research by Box using ice cores — long cylinders drilled out of the ice sheet that let scientists sample hundreds of years of ice layers — showed that in the past, snowfall has increased over the ice sheet as temperatures have risen.

However, changes in the distribution of snowfall through the year, conceivably linked to increases in sea surface temperature, may have reduced the reflectivity of the glacier and played an even bigger role in forcing the retreat than changes in air temperature alone.

Indeed, snowfall is often predicted to increase in many regions in response to anthropogenic climate change, since warmer air, all other things being equal, holds more moisture, and therefore, the potential for greater amounts of precipitation whatever form that precipitation takes.

2) In many scenarios, warming results in increased snowfall resulting in glacier lengthening as a direct result of climate warming.

Without the moderating effects of increased snowfall and refreezing, post-1996 Greenland ice sheet mass losses would have been 100 % higher.

Increased winter snowfall meant that a few, most notably in New Zealand and Norway, got bigger during the 1990s, he said, but a succession of very warm summers since then had reversed the trend.

The open Arctic is such a prolific producer of precipitation that the increased winter snowfall amounts to more than the oblique rays of the sun can melt away during the short northern summer.

You declare AGW theory to be theology, and merely cite «studies» and make a number of assertions, some of which may be true statements and yet are irrelevant, and, at worse, misleading, with respect to the case for AGW (for example, increased snowfall in a region is no indicator of the rate of energy storage in the biosphere).

This should be put into context, as Zwally also says that within a couple of decades (should the current loss rate remain) the losses will catch up to the gainings: «If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same rate they've been increasing for the last two decades, the losses will catch up with the long - term gain in East Antarctica in 20 or 30 years — I don't think there will be enough snowfall increase to offset these losses.»

the heavier snowfalls will increase the albedo of earth, which will cool the land and the oceans.

Moreover, the increase in atmospheric water vapor content in the Arctic region during late autumn and winter driven locally by the reduction of sea ice provides enhanced moisture sources, supporting increased heavy snowfall in Europe during early winter, and the northeastern and mid-west United States during winter.

I can certainly see that SOME CO2 level would do that, but everything I have read so far about Antarctic says that in a somewhat warmer climate, which we will have in Antarctica soon, Antarctic as a whole will get more snowfall, hence more retention of ice, because warmer air holds more water vapor, even if the increase in warmth is merely from minus 40 C to minus 35 C.

The effects water vapor as evidenced by the increase in the amount of snowfalls and floods should also be discussed.

Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely diSnowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely disnowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely disnowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.

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.

If snowfall increases (as in some models), the mass of ice in Greenland and Antarctica may increase, even if there is more melting and calving of icebergs at the edges.

This can be affected by warming temperatures, but also by changes in snowfall, increases in solar radiation absorption due to a decrease in cloud cover, and increases in the water vapor content of air near the earth's surface.2, 14,15,16,17 In Cordillera Blanca, Peru, for example, one study of glacier retreat between 1930 and 1950 linked the retreat to a decline in cloud cover and precipitation.18

In many parts of the world, water supplies are under increasing pressure from growing human population, demographic changes and climate change, which is changing the rules by which rivers, rain and snowfall, and annual storms have operated for thousands of years.

«As it turns out, the scientific community has been addressing this particular question for some time now and they say that increased heavy snowfalls are completely consistent with what they have been predicting as a consequence of man - made global warming.»

Heavy snowfall and snowstorm frequency have increased in many northern parts of the United States.2 The heavier - than - normal snowfalls recently observed in the Midwest and Northeast United States are consistent with climate model projections.

In the Midwest, lake - effect snowfall has increased along and near the southern and eastern shores of the Great Lakes since 1950.

The layers formed with each year of snowfall gradually disappear with increasing compression.

Proponents of human - caused global warming might claim that climate models predict increased snowfall in the Antarctic, because more warmth draws more moisture into the air that snows out.

«Projections of Antarctic SMB changes over the 21st century thus indicate a negative contribution to sea level because of the projected widespread increase in snowfall associated with warming air temperatures (Krinner et al., 2007; Uotila et al., 2007; Bracegirdle et al., 2008).

If you are focused on simple thermodynamic reasoning, don't forget about increased snowfall from warmer ocean temperatures, that can temporarily (for say a few thousand years) increase mass balance of the continental glaciers.
