Answer quesitons - Essay ExampleThis backside cause confusion, and much worse. Sometimes people even use this confusion to promote their own goals, politically or otherwise. This is what has happened with the flow rate climate change debate. An objective look and scientific data show that climate change is in particular happening, that, historically, a shifting climate rather than a stable climate is the norm on Earth, and in that respect is a relationship between carbon in the atmosphere and global temperature though there are also a great deal of complicating factors as tumesce.On the one hand, it would appear that it is precise difficult to establish a historical trend of world temperatures we have only been measuring and put down temperatures for around the past one hundred and fifty years before that we supposedly know in truth little. And on the surface this is true, we do not know exactly what temperature existed before the menses period. But this belies the fact t hat there are excellent proxy mea sure as shootingments that have been shown to be relatively accurate when calibrated to current temperatures. We have ice-core samples that demonstrate how much snow has fallen in particular years, which cease give a rough gauge of temperatures (National Research Council), as well as tree rings which show how well trees grew in a particular year (NRC). This data, when taken collectively and studied with statistical and scientific eye, can give a relatively accurate approximation of temperature over the last two thousand years. This can be combined with historical records (good and bad harvests, for instance, or records of when lakes and rivers freeze and when they do not), to be extra sure that the calibration is accurate, which has been done by several scientists/historians (Edwards 129). But this is something that lay people have a vexed time understanding, which might cause some to doubt their findings.These
