Journal of Great Lakes Research. 22 (1996): 845-863. For William Hryb, the effects of climate change on shipping routes in the Upper Great Lakes "all boils down to a good old-fashion crap-shoot." Lakes play a much greater role in global carbon cycling than their area would otherwise predict. Lakes, natural and artificial, modify the climates of their surrounding areas. The lower layer of air, heated up by the lake water, picks up water vapor from the lake and rises up through the colder air above; the vapor then freezes and is deposited on the leeward (downwind) shores.. See how global warming has imperiled salmon in the Columbia River, Oregon —and find other hot spots threatened by higher air temperature on the Climate Hot Map . OVERVIEW: Changing Weather & Climate in the Great Lakes Region This 9-minute video features CIMSS Director Steve Ackerman employing NOAA weather data and findings from the 2014 National Climate Assessment (NCA) and the 2013 Intergovernmental Panel on Climate Change (IPCC) to provide an overview on global climate change and recently observed changes in Great Lakes weather and climate. Lake effect snow buries parts of the Great Lakes in December 2016. How do the Great Lakes affect climate :D?._. The Great Lakes region is warming faster than the rest of the U.S., which likely will bring more flooding and other extreme weather such as heat waves and drought, according to a scientific report. By mid-century (2050), average air temperatures are projected to increase by 3°F to 6°F (1.7°C to 3.3°C). Monday, October 15, 2018, 6:10 PM - Get ready, southern Ontario! “The climate assessment puts the Great Lakes in the bullseye of climate … These modifications are known collectively as lake effects and extend from the microscale to the synoptic scale. Scott, R. W., and F. A. Huff. How Do the Great Lakes Affect Temperature? Climate change is already beginning to affect plants and animals that live in freshwater lakes and rivers, altering their habitat and bringing life-threatening stress and disease. The Great Lakes, which are Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario, form the largest group of freshwater lakes on Earth. Climate change is already beginning to affect plants and animals that live in freshwater lakes and rivers, altering their habitat and bringing life-threatening stress and disease. 8 years ago. "Impacts of the Great Lakes on regional climate conditions." The Western region of the Lakes tends to be drier, while the Southeast area tends to have far more precipitation (“lake-effect” snow and rain). Models that do not simulate the Great Lakes should be flagged for a high amount of uncertainty. because of size and location lake michigan plays the biggest part in creating the 'lake affect' Estimates oflake-inducedspatial changes ofsix climate variables (precipitation, mean Areas near the lakes are generally cooler in the Summer and warmer in the colder months, until the lake freezes over then we … Each of the last three years were records in terms of mean global temperature over the past 150 years. While lakes make up less than 2% of Earth’s surface area, they bury over three times more carbon in their sediments than all of the world’s oceans combined 2.This means on a per area basis lakes bury over 100 times more carbon than the oceans. Related. Lake effect snow across the Great Lakes occurs as a result of cold air rushing over relatively warm—and ice free—lake waters. Relevance. Lake Effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. Great Lakes, chain of deep freshwater lakes in east-central North America comprising Lakes Superior, Michigan, Huron, Erie, and Ontario. 3 Answers. Editor’s Note: This is the first in a series of stories on how climate change is expected to affect the Great Lakes region. Our warming climate is already causing negative effects like declining ice cover and increasing surface temperatures, changes that can be majorly disruptive to a lake's normal processes. Cold air that travels over water for a long enough distance will not only warm enough to begin to rise but also grab enough moisture from the lakes to … Lastly, as can be seen, some unique weather phenomena take place surrounding the Great Lakes such as lake effect snow. These far-reaching impacts emphasize the need for continued monitoring and modeling of the Great Lakes as our climate continues to change. The combined area of the Great Lakes—some 94,250 square miles—represents the largest surface of fresh water in the world, covering an area exceeding that of the United Kingdom. Lv 7.
