Increased Heat Waves

Cari Hauge's insight:

Climate change will cause more frequent and more intense heat waves. The increased frequency and intensity of heat waves have been seen impacting human lives in the intense Chicago heat wave in 1995. The impact of this change in Wisconsin could be increased mortality due to heat for people in homes not prepared to handle it.

Climate change impacts on soil erosion rates.

Cari Hauge's insight:

This article states that the increased precipitation from climate change will increase the rates of erosion in areas that will receive higher rates of rainfall. They also postulate that areas that revive lower rates of rainfall do to climate change will also experience higher rates of erosion due to loss of vegetation. Increased rainfall amounts and increased intensity of precipitation will increase erosion according to all the models analyzed in this study - the rate at which the will be effected is still unknown, but the study can predict that erosion will increase 1.7% for each 1% change in temperature.

Effects on the Great Lakes and Aquatic Ecosystems.

Cari Hauge's insight:

This article discusses the changes that may occur in the Great Lakes and how changes in the lakes could affect aquatic life. The warming of the lakes and increased annual precipitation. It indicates that some of the smaller lakes to the south may not freeze over. The thermocline depth would change with warmer climates. 

The research indicates that the habitat for warm, cool, and cold water fish would increase in some lake but may decrease in other lakes and streams. The boundary for fish species would move north and invasion of warmer water fish may occur.

Wisconsin Initiative on Climate Change Impacts - WICCI : Adaptation Science

Wisconsin Initiative on Climate Change Impacts - WICCI : Adaptation Science | Effect of Climate Change in Wisconsin | Scoop.it
Cari Hauge's insight:

This lists potential impacts and already observed impacts of climate change on Wisconsin.

 

This publication indicates that water sources will be effected and that with the shifting temperatures and precipitation, Wisconsin should expect more precipitation in the winter and with warmer temperatures it should expect more rain and more freezing rain. Other effects on the hydro-logic cycle include shorter periods of ice cover on the lakes and more phosphorous containing runoff into lakes. 

 

The publication also analyzes potential impact of climate change on crops such as corn and soybeans. It includes positive potential impacts, neutral potential impacts, and negative potential impacts. 

 

The publication includes information about migratory changes over the years and how species are migrating earlier. The data shows changes in geese, robins, and cardinals.

Effect of Climate Change on Agricultural Crops

Click here to edit the title

Cari Hauge's insight:

This research discusses the effect of climate change on crop yield over many years. It notes that some crops will not be significantly affected while others will be more effect. Some Wisconsin crops, such as Maize and Wheat will produce a lower yield, while other crops such as soybeans may not be significantly impacted.

Phenological changes reflect climate change in Wisconsin

Cari Hauge's insight:

This article examines a variety of life cycle indicators for Wisconsin species and their change over time. They noticed that some events appeared to affected by the warming and some did not. They express concern that the ones that are not adapting to the warming may face species survival issues in the future. Examples of events that were significantly effected include the migration of geese, robins, red winged black bird, and many other birds. Their data showed that some plants were blooming earlier such as the Hepatica, Common and Marsh Milkweed,  and Spiderwort.

Patterns of climate change in Wisconsin from 1950 to 2006.

Cari Hauge's insight:

This resource presents an analysis of climate change in winsconsin. The article concludes that nightime lows have increased .6-2.2 degrees celcious and daytime  hights have warmed .3-.6 degrees celcious. In centeral and southern wisconsin, precipitation has increased 50-100mm (10-15%) but in far northern wisconsin precipitation has declined 20-60mm. Their data shows that winter and spring temperatures are more effected than other seasons. The believe the growing season has lengthened 5-20 days in Wisconsin.

Icing of Lake Mendota

Click here to edit the title

Cari Hauge's insight:

This article discusses the ice changes in ice cover in Lake Mendota. The data showed that local climate has a linear relationship with ice cover. They found that the variable in local climate that had the most impact on ice cover was temperature. The ice cover and ice-off date were both effected by temperature. The ice off date is earlier for warmer temperatures.

Climate Change & Variability in the Midwest

Cari Hauge's insight:

This website shows the temperature and precipitation trends in Wisconsin and other states in the midwest. The data shows that there is a trend through the whole year of warming, but the most significant impact occurs during the winter season in the midwest.

Effect of Climate Change on Wisconsin Trout

Cari Hauge's insight:

In this research, scientists measured the temperature of a stream using technology in an airplane. Based on what they know about trout mortality, they conclude that if the stream continues to warm up, it will reach the point in which it will cause death. At higher temperatures trout metabolism, growth, and physiology. Cold-water fish are at risk if the rivers continue to warm up.
