We've already started having a decreased snow pack and increased wild fire frequency.
Nonetheless, the results in two different modes (event and continuous simulation) provide support to the speculation that the decreasing trend in flood peaks was a result of decreasing snow depth.
Scientists have for the first time drawn concrete links between the planet's warming atmosphere and changes that affect Americans' daily lives and pocketbooks, from tidal flooding in Miami to prolonged water shortages in the Southwest to decreasing snow cover at ski resorts.
An Arctic "report card" for 2013, presented to the American Geophysical Union last week, found that the long-term trends in the polar region continued to show that it is warming rapidly and as a result has experienced dramatic changes, such as decreased snow cover, melting permafrost and diminishing ice both on land and sea.
Indeed, studies have revealed a link between decreased snow depth and seal pup mortality.
With decreased snow cover resulting in decreased runoff, groundwater recharge in the Helmand River basin is likely to be decreasing substantially, as well.
Precipitation data are scarce in Afghanistan, but regional data show a long-term trend of decreased snow cover, and therefore strong likelihood of decreased aquifer recharge.
Multi-decadal trends also show decreasing snow cover in the region, a particularly alarming result because the alluvial fan aquifers supplying water to the karezes depend upon recharge from snowmelt-fed, influent rivers.
Climate change models predict that the Arctic sea ice will continue to shrink in a warming world (as much as 40% of the ice is expected to be gone by midcentury), and the resulting changes including later formation of ice in the autumn, rain falling on the snow, and decreasing snow depths will make it increasingly difficult for the seals to construct their snow caves, NOAA says.
