Sentences with phrase «with widespread melting»

Maximum temperature extremes were also associated with widespread melting of the Greenland ice sheet.

Not exact matches

«Warming greater than 2 degrees Celsius above 19th - century levels is projected to be disruptive, reducing global agricultural productivity, causing widespread loss of biodiversity and — if sustained over centuries — melting much of the Greenland ice sheet with ensuing rise in sea levels of several meters,» the AGU declares in its first statement in four years on «Human Impacts on Climate.»

The vision is enticing: if bodyfat can simply be melted away with new active ingredients, then this could also prevent the widespread consequences of obesity — such as joint problems, diabetes and cardiovascular diseases.

The decreasing trend in global snow cover and widespread melting of glaciers is consistent with a widespread warming.

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 difficult.

These tipping points could be ice sheets on Greenland and Antarctica melting permanently, global food shortages and widespread crop failures with more extreme weather, rising ocean temperatures and acidity reaching triggering a crash in global coral reef ecosystems, and warming oceans push the release of methane from the sea floor, which could lead to runaway climate change, etc..

As reported by Don Perovich aboard the Healy, there is widespread refreezing of surface ice meltwater as it runs through, then underneath, the ice and comes into contact with colder, more saline seawater, adding on layers of newly formed ice to the bottom of floes during the melt season.

Field observations and a drifting buoy tracking through the region also reveal that widespread refreezing of surface ice meltwater as it comes into contact with colder, more saline seawater, has added ice layers to the bottom of floes, slowing down thinning and melt of the ice cover.

This was the first widespread Antarctic melting ever detected with NASA's QuikScat satellite and the most significant melt observed using satellites during the past three decades.

Further evidence for forced changes arises from widespread melting of the cryosphere, increases in water vapour in the atmosphere and changes in top - of - the atmosphere radiation that are consistent with changes in forcing.

«With both the frequency of forest fires and warmer temperatures predicted to increase with climate change, widespread melt events are likely to happen much more frequently in the future,» Keegan sWith both the frequency of forest fires and warmer temperatures predicted to increase with climate change, widespread melt events are likely to happen much more frequently in the future,» Keegan swith climate change, widespread melt events are likely to happen much more frequently in the future,» Keegan says.

An increase of this magnitude could trigger widespread melting of the permafrost in Arctic regions, with unpredictable results.»
