The hockey stick controversy and the legitimacy of IPCC's about the human impact on climate change - Research Paper Example The controversy also looks at the question of the sturdiness of the impost offered by the Intergovernmental Panel on Climate Change (IPCC). These arguments have been taken up by the fossil fuel industry and have been funded by lobby groups that attempt to cast doubt on climate science. The controversy became prominent in the 1990s when a group of scientists who used proxy indicators to indicate temperature records in the previous centuries found different reasons that caused global warming and argued them differently (Jolis, 2012). A group of scientists such as Michael E. Mann, Raymond S. Bradley, and Malcolm K. raised some of those controversies by using statistical analysis of an assortment of proxies to come up with the first quantifiable hemispheric-scale reconstruction presenting global configurations of annual surface temperature. The graph shows temperatures that dates back to 1400 whereby they shaded the areas to show emphasis of uncertainties whereby the two standard error l imits were larger than in earlier centuries. The above group of scientists published a paper in 1999 that traced back climatic changes for the previous 1000 years using extended graph that showed a descending tendency in proxy temperatures from a medieval warm period trailed by a 20th century escalation and a steep upsurge in measured temperatures since the 1950s. According to United Nations Intergovernmental Panel on Climate Change (IPCC) and Third Assessment Report (TAR), the year 1998, was the warmest year in the northern hemisphere for the last 1000 years. The above organizations used the controversial hockey stick graphs to publicize the featured information. The information became a focus for dispute for the people who were contrasting to the strengthening scientific agreement that late 20th century warmness was unique. Some of the scientists who were opposed to these changes were Willie Soon and Sallie Baliunas. However, scientists later dismissed their publication as deeply flawed (McKitrick, 2010). I also disagree with the legitimacy of the previous research used by the United Nations Intergovernmental Panel on Climate Change (IPCC) since their research shows less dramatic results if techniques that are more reliable had been used to analyze the data. Later researches have shown that an increase in greenhouse gases due to human activity is a prime cause global warming. However, arguments in favor for global warming were already accepted widely as a prime cause for increased temperatures in the world. Conclusions made from other scientists shows that making the world warmer undoubtedly is not determined by reconstructions of temperature aforementioned to direct records. Most error pieces fall inside the stated hockey stick pieces created by Mann and his team of scientists but can be collected to indicate the late temperatures. There are major doubts about the correctness of all previous temperature re-establishments, and these qualms have sometimes to be glossed over by scientists who presented the hockey stick as suggestion for global warming (Regalado, 2005). Michael E. Mann, Raymond S., Bradley, and Malcolm K., have remodeled northern hemisphere temperatures for the previous 2000 years to incorporate a wider set of proxies than what was accessible for the original study and updated measurements from the late years. I the new reconstruction, different methods am used as compared to the previous methods used in the original case. It shows

Social care workers need to develop the knowledge and skills to work Essay

Social care workers need to develop the knowledge and skills to work effectively with people from similar and diverse background - Essay Example Thus, in discharging the professional duties and accomplishing social tasks, social care workers need to work hard and develop adequate cultural competence. Acceptance among the masses is a precondition to the successful workability of a care giver. Anti-oppressive practice should, therefore, be adopted and proper changes in the service-user communities should be initiated. In the course of cultural competence development, anti-racist practice must focus on the discriminations based on colour and race (Sue, 2006). Improvement in social work development and training can be brought about by the means of thorough comprehension of people’s family arrangements, social norms and values. Social work and support in a culturally sensitive environment has to be based on exploration of the diverse cultural heritages (Laird, 2008). Finally, the research question is in the form of the following statement: Social care workers need to develop knowledge and skills to work effectively with peo ple from similar and diverse backgrounds. Describe one model of cultural competence and discuss the potential benefits and limitations of applying the model. Therefore, this paper will explore a suitable cultural competence model and proceed on related discussions. ... A cultural group’s objective cultural attributes, such as art and music, are important and are included as implied assumptions. The primary and secondary characteristics of culture, developed from and expanded upon from Hage’s (1972) variable and non-variable concepts are nationality, race, colour, gender, age, and religious affiliation. Secondary characteristics are educational status, socioeconomic status, occupation, military experience, political beliefs, urban versus rural residence, enclave identity, marital status, parental status, physical characteristics, sexual orientation, gender issues, reason for migration, and immigration status. (Purnell, 2002) At the outermost interface of the model, the global society is placed. Next, there is the interface of community followed by the layer of family. The inner interface represents the person, the metaparadigm concepts. Inside this interface related to the individual, twelve cultural domains have been depicted. The dom ains are interrelated and they affect each other. The twelve domains are: 1. Overview/ Heritage: Includes concepts related to the current residence and country of origin, reasons for emigration, occupations, educational status, etc. 2. Communication: Includes concepts related to the contextual use of language, dominant language and dialects, paralanguage variations, nonverbal communication, etc. 3. Family roles and organisation: Includes concepts related to social status, lifestyle issues, child rearing, gender roles, family roles, etc. 4. Workforce issues: Includes concepts related to ethnic communication styles, assimilation, acculturation, autonomy, individualism and healthcare practices from the country of origin. 5. Biocultural ecology: Includes variations in ethnic and racial origins,
