Blizzards affect people by shutting down cities and transportation systems, damaging property, hurting the economy and causing injuries and loss of life. This decades-long western wind is unusual for the region, where previously, the winds changed direction every five to seven years. This is what a blizzard looks like. Climate change can also influence the amount of fresh water available from melting winter snow. In mountain ranges such as the Sierra Nevada in California, snowpacks that release water gradually during warmer months serve as the primary source of drinking and irrigation water. Still, by most of the metrics experts use to describe winter climate, Overland agrees the big picture is clear: on average, winters are warmer and cold extremes are less likely than they were a century ago. The Environmental Protection Agency says that such storms have the potential to cause significant damage to entire forests, which then release carbon during decay. Trees are part of the biosphere (living things) but affect the land (geosphere), air (atmosphere), water (hydrosphere) and other living things (biosphere). Under the high-pressure ridges, warm air floods north into parts of the Arctic, often driving extreme melt, while polar air fills the low-pressure troughs, bringing wintry conditions farther south than average. Most of the time when this happensand it happens on average about every other year in the Arcticsome part of the mid-latitudes will ultimately experience a cold air outbreak. That trend is likely to continue with rising greenhouse gases and more global warming. The storm produces ample snow while strong winds develop because of a difference in pressure between the low pressure of the storm and the high pressure beyond the storm. How Do Blizzards Affect The Scientists expect climate change to amplify the ocean warming and the undercutting of those Greenlandic glaciers. Rexana Vizza / Matthew Segal According to Butler, the idea isnt as counter-intuitive as it seems at first glance. How Does Observations from space show that the rate of sea level rise is increasing. In addition to comparison views of before-and-after images, you can now view selected scenes as time-lapse sequences generated via the Google Earth engine. There also appears to be a tug-of-war between climate change processes that could strengthen the Arctic polar vortex and processes that could weaken it. They flow like rivers, only much slower. ellen.t.gray@nasa.gov The missions have measured variations in Earths gravitational pull in response to surface mass and water changes. But it hasnt continued, and more and more, its looking like what seemed to be the beginning of a trend was just natural variability, or maybe just a rebound from the quiet of the 1990s.. Be afraid. The uncertainty due to a relatively short history of observations isnt the only reason experts cant dismiss the possibility that something could be up with polar vortex. As part of NASAs Oceans Melting Greenland mission, which surveys glaciers with aircraft and ships, scientists want to gain a better understanding of how ocean warming affects coastal glaciers. By combining expertise about the cryosphere with field campaigns and an extensive fleet of operational and upcoming satellites, NASA and its partners can help communities worldwide to predict the effects of climate change and to potentially mitigate natural hazards and disasters that are deeply connected to our planets cryosphere.
