The Great Warming: Critical Analysis In a time referred to at the Medieval Warm Period, the earth faced a rise in temperature that altered the climate worldwide. In a New York Times Bestseller, The Great Warming, written by Brian Fagan, we learn how the history of the world a half millennium ago implies that we still are misjudging the power that climate change holds. Brian Fagan, an anthropologist at the University of California, Santa Barbara, works his way across the globe to find evidence explaining the interaction of climate change and human societies. Fagan finds evidence of climate change in areas on western Europe, where longer summers and shorter winters led to plentiful harvests and population growth, evidence of severe droughts were found in modern-day California, violent climatic swings took place in Northern China, and in southern Yucatan, arid…
The book Heatstroke: Nature in an Age of Global Warming by Anthony D. Barnosky explains how mother nature and the wildlife is getting affected by global warming. Living patterns all over the world are alternating due to global warming. The author includes vivid descriptions of how the environment or area of a certain region has changed and his own personal research and expeditions. An emphasis is placed on what was the change in the environment. For an example, at Tambopata, they have gathered data and suggested that the heat is causing the water to evaporate from the soil faster.…
PART 1Case Study: The Canadian Red Squirrel and how it has evolved as a result of climate change Figure 1Canadion Red Squirrel The Canadian red squirrel (Tamiasciurus hudsonicus ) has shown species change as a result of climate change. Throughout history, archaeological evidence suggests DNA, Genetic Information and Inheritance, and Changes in a Species. that major environmental changes in climate, such as those that occurred in the Triassic era and the Ice Age have resulted in species changes. Scientists have presently observed species changes due to the current global warming trend.…
Raven et al. (2014) defines biogeography as a study of the geographic distribution of species, and ties tougher how the species are related or not related and natural selection. Moseley et al. (2014) define biogeography as the study of patters that may form in the biotic environment and we can use the scientific process and information gathered from the past and present to study the distributions of plants and animals. Moseley et al.…
1. Discuss three types of barriers to vertebrate distribution and give an example of each. (1) Physicalbarriers: This one of the barriers that the vertebrates usually encounter during their life. Land is one of the main factors that contributes to physical barrier since some of the species are constrained in specified geographic factor and also some physical conditions. Water is also another constrain i.e. for other species get constrained.…
All organisms derive from one common ancestor; however, the reason why organisms do not all look alike is because of evolution. When it comes to survival of the fittest it is all about who can adapt the quickest and evolve in order to keep the species alive. Two main factors come into play in evolution: abiotic and biotic factors. Organisms are constantly fighting abiotic forces such as weather. Weather or change of weather is one of the biggest reasons for organisms evolving.…
Ecosystems dependent on sunlight would experience the most adverse effects of global ice cover (DUJS, 2010). This statement is supported by evidence that carbon-isotope ratios from this period are similar to those found in the Earth’s mantle, indicating that photosynthesis was non-existent, and most forms of eukaryotic life were destroyed. However, microfossils have been found that date back to this time, of both prokaryotic, as well as a few eukaryotic fossils. This suggests that not only did organisms survive, they adapted to shallow water carbonate environments. Furthermore, the fossils that were found resemble those that were discovered in rocks slightly younger than the snowball event, strengthening the idea that there were organisms that survived the mass glaciation.…
Therefore, the impact of historical experiences on species (trees and plant life) relative to climate change today must be taken into…
In the Miocene, crucial events occurred in the evolution of climate was a cooling down of ocean temperatures globally by way of bridging the warm period of Paleogene to the cold temperature of Neogene period. The state associated with the record of the expansion of the ice volume in Antarctica, the excursion of the isotope along with the dropping deep-sea temperature (Singh and Gupta, 2004; Savin et al., 1981; Kennett and Barker,…
It's the year 2134 and the world was enjoying the longest period of peace that began back in 2073. That was the year a new mining method was discovered which made getting minerals, metals, and other resources very easy however that was way before Jerome was even around. The world had changed a lot since then and would probably never be the same. When the new method of mining came about no one knew just how bad the consequences would be. The new mining method made it possible to drill deeper than ever was thought possible; however, the effects of this was that the core of the earth was slowly starting to cool down.…

Although animals might struggle to live under the two effects above of global warming for now, animal species completely cannot make it through for the rest of their lifetime because animals cannot improve their bodies’ structures to adapt the change in their habitat. For this effect, cold-blooded animals are specific examples; according to the article “Amphibians Don’t Cozy Up to Warmer Climes,” based on the information of researchers at Stony Brook University, warmer environment shortens cold-blooded animals’ duration such as fishes, amphibians, crustaceans, and lizards because the constructions of their bodies are more appropriate for the cold environment (Leonard, page2). While global warming continues to affect animals’ lifespan, everyone can tell extinctions will possibly happen soon for a great number of animal…
eight species are significantly correlated with temperature and seven species arriving earlier during warmer years. (Elizabeth R.E et.al) Scientists at Fargo, ND have studied 83 species of birds for their arrival time over ten years. The study concluded that the majority of arriving earlier than they did historically. The uniqueness of this study is that they measured FAD (First arrival dates) and AGDU (Accumulated growing degree units).…
the biggest impact of climate change is the melting of glaciers; because of the high temperatures glaciers are melting and raising sea levels. The problem behind this is the lower regain are being submerge in water, pulse the glaciers themselves holds 70% of freshwater and if they melt it mighty mass with how ocean currents operates. (Transition between main points: the raise of temperature has affected many natural wildlife and the...) III. the environment has also been effected by the changes that causes global warming, with the glaciers melting Antarctic ecosystem is in disarray. A.…
When a species is exposed to changes in environmental conditions, it can either adapt to new conditions or die out (Brown and Lomolino, 1998). Varying environmental factors affect environments differently, no single species can be able to withstand all conditions since they not uniform for all places. A single species can only be well adapted to its distinctive environment. Environmental changes in most cases often force species to change rapidly along with…
