Scientific Uncertainty Web-Based - Assignment Example

He is concurrently vice chairman of the International Academy of Education (The Heartland Institute, 2012b). Its stated mission is the discovery, development, and promotion of social and economic solutions to problems based on free-market economics (The Heartland Institute, 2012c). It is a fierce skeptic of global warming. Their agenda seems non-partisan, but the ties of the leader suggest being pro-big business, as a prominent Republican. Consequently its values are those of the conservatives (The Heartland Institute, 2012; University of Illinois, 2012).

NASA is a global warming proponent and posits that human activities are at the core of recent unprecedented trends towards warming with consequences to humans and the ecology. It is a government entity receiving funding from the current Democratic leadership. Its agenda cum mission is implied in its stand: to present mainstream scientific data on climate change. Its values are nonpartisan, science-based, and arguably tinged with Democratic principles owing from the Democratic leadership (NASA, 2012).

Skeptical Science has as its mission essentially the advancing of climate change arguments and the debunking of arguments against climate change science by deniers and skeptics of climate change. It has support from a wide stratum of scientists and academicians with nonpartisan interests throughout the world, and is a repository of data and articles that support its implied mission. Its values seem to include openness, diversity, and inclusion of all available data, without prejudice, and with no funding or overt agenda other than the truth (Cook, 2012). 2. Key Evidence Presented by Websites on Ice Melt and Climate Change, Stated Evidence Sources Skeptical Science updates evidence and data about climate change routinely, coming from contributors who are scientists and academics from all over the world.

Examples include experiments on computer modeling relating to the way the permafrosts are being thawed due to climate change, citing prior research by reputable scientists published in Nature GeoScience in 2012. Another example details results of studies on climate change with data inputs from African data sampling expeditions, as well as other permafrost melting studies, all referenced and published in reputable scholarly journals (Cook, 2012). NASA likewise cites evidence from scholarly sources, including from the National Research Council, the UNSW Climate Change Research Center in Sydney, the journal Science, and the IPCC.

For instance, evidence with regard to man-made global warming and the fast pace of its acceleration over the last 1,300 years are documented and presented in the NASA site, complete with graphical presentations of CO2 emissions over the past 650,000 years, and properly referenced from an IPCC report. Ice core research confirming global warming trends were attributed and visibly cited from a 2006 research study by the National Research Council (NASA, 2012). The Heartland Institute in turn presents data that refute ice melt and global climate change, coming from sources reportedly from the US Energy Information Administration, among others.

(The Heartland Institute, 2012). One paper presented as an article containing arguments against the reality of global warming meanwhile, from the Heartland Insti
