Climate Change Of The California Valley Oak ( Quercus Lobata )

The Earth has been affected by climate change in many ways but the most important result in this weather change is the amount of species whose populations are decreasing. Organisms and even humans are much needed for our world to run property and without one of those species, the entire system would be messed up. In Document C, it shows how the weather is making a bad organism spread and kill many plants. Our world needs plants to survive and with all these plants dying it will greatly impact the food web, causing many

plants can't change and adapt along with the rapid warming of the earth, which will

Climatic changes are expected to change species distributions, phenologies, interspecific interactions, community composition, and ecosystem function (Schneider & Root 2002). Many of these impacts have already been observed (Parmesan 2006). In California’s San Joaquin Valley, temperatures are projected to be warmer in both winter and summer, with a mean annual increase of 1.4–2.0°C by 2070 (PRBO Conservation Science 2011). Additionally, precipitation is projected to decrease (-9% to -30%), although there is a high degree of uncertainty surrounding the magnitude of the precipitation changes (PRBO Conservation Science 2011). Summer heat waves are projected to become longer and hotter, and droughts more severe (Garfin et al. 2012).

Most of us consider drought as a period of dry and hot weather with too little or no rain, and while any or all of these conditions might be existent during drought, the definition of drought is more complex and subtle. According to the United States Geological Survey, California Water Science Center (as cited in Congressional Digest, 2015, p. 2):

Because most greenhouse gases would remain in the atmosphere for a long period of time, the temperature of the earth will be continuously rising. If global heat-trapping emissions proceed at a medium to high rate, temperatures in California are expected to rise 4.7 to 10.5°F by the end of the century1. With the rise of temperature, the climate of California would also be changed. California has large area of forest and farmland, hundreds of miles of coastline, large amount of snowpack, and other natural wonders. And these special treasures of nature are especially at risk2. So it is very necessary to understand the strategies of California to combat climate change.

In the text it clearly states, “ Most organisms are adapted to live within a particular range of temperatures and will not survive at temperatures too far above or below their range.” So it really depends on the climate range in the area a certain plant is living in but most animals survive in most types of weather.

The framework begins with the object under study, which is the content discussed in each essay, and how the objects in the essays are described. The Theobald essay discusses the lack of connectivity between different species due to human destruction of the wilderness. The abstract of this essay states, “The potential for ecosystems to adapt to climate change will be contingent on the ability of species to move and ecological processes to operate across broad landscapes” (Theobald et. al 123). Humans have been eliminating the habitats of animals because of development, and this is making it harder for the animals to adapt and move where they need to.

The species and places depend on intricate ecosystems, and even small changes to the climate can disrupt the delicate balance of nature.

California is one of the most progressive states in America, and is constantly evolving and advancing in fields such as technology, food, and entertainment. The biggest change in California is not one of those three but rather the climate. Climate change is a term coined by physicist Gilbert Plass during the 1950’s to describe the total change in global climate patterns. In his research Plass discovered that the earth was heating up due to carbon dioxide emissions trapping heat from escaping the earth’s atmosphere. What he really discovered was the connection between climate change with global warming and the greenhouse effect. California specifically has contributed significantly to carbon dioxide emissions and the warming of the earth. We

Imagine going on a nice trip to California but you couldn't anymore because of a wildfire. Wildfires are a huge problem, not just wildfires there is also droughts, hurricanes, and floods. All are caused by Climate change which is a huge problem that needs to be stopped.

In the article “The Seasons Aren’t What They Used to Be,” David George Haskell berates that fact that climate change is evident in most forms of life around us, however, humans have refused to acknowledge the obvious signs and take necessary action. Haskell is a professor of biology on the faculty of Sewanee University in Sewanee, Tennessee. He holds a Bachelor of Arts from the University of Oxford, and a Ph.D. from Cornell University and writes about biodiversity, evolution, and conservation. Haskell education background and experience give him the credibility to speak on the effect of climate change. Haskell’s purpose is to point out the signs of the changes in season triggered by climate change and its effect on plant, animal and human

Shifts in temperature and precipitation will be a shock to fragile ecosystems which depend on specific climatic conditions. Many species will be unable to adapt as fast as their environment changes and face sharply reduced numbers or extinction. Scientists estimate that a warming of just 2 degree will put as many as 30% of the world's species at risk of extinction. Plants and animals aren’t the only ones feeling the pressure of changing ecosystems. Many regions will face severe water shortages in a warmer world, creating the potential for conflict. It is believed that the genocide in Sudan’s Darfur region is at least in part a response to water shortages resulting from global warming.

An example of a pro with assisted migration involves a Mexican pine species, Pinus leiophylla and its relocation to a habitat that involved changes to the altitude in anticipation of the expected shift in altitudinal range due to climate change. “Scientists predict an upward shift in altitude of 300m is required to compensate for the expected 1.5C increase in average temperature” (Castellanos-Acuña, Lindig-Cisneros, & Sáenz-Romero, 2015). The research demonstrates that the Pinus leiophylla exhibited similar growths at all altitudes and would not result in a severe maladaptation, allowing survival at this altitude.

Habitat can be considered as the optimal location where any one species can live, reproduce, and grow in an ecological time scale (Kellner et al. 1992). As the climatic conditions of the world are changing at a rapid pace, it is important to understand how species will adapt with the weather and learn to adjust their way of living. Understanding how a species survives in different climatic regions is very important for the future management of the species population and habitat. With this knowledge an individual could more efficiently manage their habitat to make it more suitable for the species to live under the given climatic conditions.

As life scatters for its survival in a new world devoid of anything living, human extinction is soon to be imminent. The once lush Earth will either dry up or bury by immense snowfall; therefore, turning these places inhabitable by life. Don't fret, though. They are only predictions of what will happen in the near future so you can worry later. Climate change is arguably one of the most important threats that endanger life on Earth. This was the concern covered in my nonfiction reading, Six Degrees: Our Future On A Hotter Planet, by Mark Lynas. The increased use of fossil fuel and continue industrialization have caused many of the problems we faced in the 21st century in the form of Global Warming. It has created raging storms, drought, famine, and fluctuating temperatures across the globe. Although this is not a problem I face personally, it might be problems in my lifetime in terms of mounting air conditioning bill and lacking any water. Unfortunately, plants and animals are incapable of quick adaptation like us humans, and they are prime targets for climate change. By hurting the plants, we are decrementing our chance of cleansing the plagued atmosphere created by us. We are damaging the
