Discussion: Earth's Changing climate Graded Discussion
Discussion Topic
Globally, the winter of 2014-15 was the warmest winter on record at that time, but it sure
didn't seem that way for most of the eastern United States. This region experienced
record-low temperatures and extreme snowfall, especially in the northern and coastal
areas. During this period of extreme cold and snow, it was not uncommon to see
comments on social media disputing climate change. For example, some commenters
took pictures of huge piles of snow and added comments such as, "This doesn't look like
global warming."
Do these commenters have a point? Should extreme snowfall over the course of a
season cast doubt on the theory of global climate change? Make a scientific argument
explaining why you agree or disagree with these commenters.

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.
