CLIMATE CHANGE: HOW THE HOMO SAPIENS HAVE CONTRIBUTED By Ernest Ebo Jackson TERM PAPER Climate change refers to change in average weather patterns and can be caused by both natural processes and human activities. In the past‚ the earth’s climate has been affected by natural factors such as changes in solar output and the discharge of volcanic ash. In fact‚ the planet has been through many periods of cooling and warming. The last period of major cooling ended about 10‚000 years ago.

aerosols into the upper troposphere and stratosphere (Allen‚ 2015). Volcanism helped form Earth’s ancient climate and influences climate change in today’s world (Kasting‚ 1993). A recent example of a volcano influencing climate include the 1982 El Chichon eruption in Mexico‚ which is regarded as the largest volcanic disaster in modern Mexican history (Mass‚ 1989). Ancient examples of climate-changing eruptions include the Huaynaputina volcano in Peru in 1600 C.E. (Costa‚ et al. 2003) and a volcano

that support them. Natural diversity in ecosystems provides essential economic benefits and services to human society—such as food‚ clothing‚ shelter‚ fuel and medicines—as well as ecological‚ recreational‚ cultural and aesthetic values‚ and thus plays an important role in sustainable development. Biodiversity is under threat in many areas of the world. Concern about global biodiversity loss has emerged as a prominent and widespread public issue. We recognize the importance of biodiversity conservation

EFFECTS OF CLIMATE CHANGE ON WOMEN Introduction Definition of basic terms What is Weather? The term weather describes the state of the air at a particular place and time – whether it is warm or cold‚ wet or dry‚ and how cloudy or windy it is‚ for example. It affects many of the things that we do‚ from the clothes we wear and the food we eat‚ to where we live and how we travel. As a result‚ the weather is of great interest to people everywhere‚ from meteorologists‚ the scientists who study it in

Changes in the Atmosphere Causing Multicellularity About 2.5 billion years ago‚ oxygen began slowly to accumulate in the atmosphere‚ as a result of the photosynthetic activity of the cyanobacteria. Those prokaryotes that were able to use oxygen in ATP production gained a strong advantage‚ and so they began to prosper and increase. Some of these cells may have evolved into modern forms of aerobic bacteria. Other cells may have become symbionts with larger cells and evolved into mitochondria

Mitchell June 25‚ 2014 Env 101 EC Climate Change Paper What I Think Is Causing Climate Change Upon completing the summer course of environmental science‚ I have learned plenty of information about the environment around us. I learned that there are many factors that can cause climate change in the world. I now know that climate change isn’t just caused by people in the world‚ or just the world changing slowly. I believe that the change is a combination of both humans and the environment together.

The role played by weather and road conditions in accidents When you drive in bad weather it usually takes longer and can be stressful. Leaving earlier can allow you to reach your destination without worry of running late. If possible‚ take an alternate route to avoid weather systems that can affect your driving. You should drive more slowly and carefully than normal while driving in bad weather. This can reduce the possibility of accidents from skidding. When you are driving in rain

Determining Cause and Effect What: Determining Cause and Effect is a strategy to find a causal relationship between or among events‚ conditions‚ or behaviors. Why: This strategy givens reasons and explanations for events‚ conditions‚ or behaviors. It is an analysis tool to display possible cause of a specific condition or event‚ or the possible effects of a specific condition or event. How: Often cause and effect are subtle and hard to distinguish. Be sure not

Debate on Climate Change Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions or the distribution of events around that average‚ for example more or fewer extreme weather events. Climate change may be limited to a particular region or may occur across the whole Earth. I t is a broader context of human dimensions in which insufficient attention
