Scientific community:
A) Carbon dioxide levels in the atmosphere are rising as a direct result of man-made CO2 emissions from the burning of fossil fuel.
B) Carbon dioxide levels in the atmosphere are rising.
C) Rising carbon dioxide levels in the atmosphere are causing the earth to get warmer.
D) The earth's average temperature is presently getting warmer.
Three (3) of these statements are proven scientific facts (proven true). However, one (1) of these statements is more a scientific consensus (agreed upon as true), and thus more controvertible.
First you will need to figure out which three statements are scientific facts (proven true) and which one is the scientific consensus (agreed upon as true). Try to find specific data and references that support each of the statements above. You can use textbooks, internet searches or other references, but the references must be legitimate scientific sources. Do not use general encyclopedia-type websites as evidence (Wikipedia, Encyclopedia Britannica, etc,) or organizational web sites (USGS, EPA, etc.). (You may however find links or references to appropriate scientific articles at some of these organizational sites!) Try to find original scientific papers that have been peer reviewed. Do not reference non-peer reviewed books.
You will need to submit 1) a document listing each of the four statements, 2) your determination on whether each statement is proven true (FACT), or agreed upon as true (CONSENSUS), 3) the evidence that you have found supporting your determination for each statement, and 4) the reference or link that you used to support your determination.
I only need to answer the question as it applies to letter A. Whether A is proven true or agreed upon as true consensus, evidence for A, and a quick reference to support
