Sentences with phrase «snowfall increased by»

Not exact matches

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.

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.

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.

Since the 19th century, snowfall across Antarctica has increased by about 10 percent.

The likelihood of snowfall making an appearance also increases as the month develops, starting off at 10 % on December 1st and rising up to 22 % by December 31st.

And by the way, if increased temperatures can make snowfall more likely that doesn't apply to these snowfalls which took place in record breaking cold.

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.

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

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.

At Crater Lake, annual snowfall has decreased each decade since the 1950s, and the surface temperature of the water has increased by 6 degrees Fahrenheit.

The temperatures in both hemispheres are regulated by the Polar Oceans that thaw and increase snowfall and freeze and decrease snowfall.

These glaciers are fed by the massive Greenland ice sheet, which is shrinking despite recent increases in local snowfall.

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 midwestern United States during winter.

«Ice sheets now appear to be contributing modestly to sea level rise because warming has increased mass loss from coastal areas more than warming has increased mass gain from enhanced snowfall in cold central regions,» the report by a team led by Professor Richard Alley of Pennsylvania State University in the US says.

Update: This story was updated to clarify that the majority of ice loss in Antarctica each year is replaced by new snowfall; The amount of ice loss that is not replaced by snowfall is increasing, adding to the continent's contribution to global sea level rise.

That's doubly true when there is also emerging evidence — documented by Senior Weather Channel meteorologist Stu Ostro and others — that «global warming is increasing the atmosphere's thickness, leading to stronger and more persistent ridges of high pressure, which in turn are a key to temperature, rainfall, and snowfall extremes and topsy - turvy weather patterns like we've had in recent years.»

Before we had GRACE satellite measurements, the consensus was that the Antarctic would be in mass balance for a long time, with increased iceberg calving offset by increased snowfall in the interior.

Two decades ago, the Greenland ice sheet was in approximate balance - ice loss at the edges as glaciers calved into the ocean was balanced by ice gain in the interior from increased snowfall.

The research not only finds a dramatic increase in snowfall, it further explains connections in the global climate system by attributing the record accumulation to warmer waters thousands of miles away in the tropical Pacific and Indian Oceans.

If there is heavier - than - average snowfall, there will be an increased chance of flooding and an increased risk of flood damage, which is not generally covered by renters policies.
