So, last year the APES text (published 2008) had a section on carbon offsets-first time I’ve seen it in a school textbook. There are many companies out there now marketing carbon offsets to reduce your “carbon footprint.” Terrapass is a popular one. You can offset one year’s worth of air travel (an estimated 8,000 pounds [...]
In class on Tuesday we spent most of the period discussing the evidence (the things we see happening) that shows the earth is warming. The first piece of evidence we have are record global temperatures. NASA concluded 2009 to be the second warmest hear on record. With average global temperatures continuing to increase each year, [...]
Today we discussed potential solutions to the problem of the enhanced greennhouse effect, also known as global warming. The only way to truly solve this problem is to attack the problem at its source: Greenhouse Gases. We need to decrease the amount of greenhouse gases, especially Carbon Dioxide, in the atmosphere by either reducing the [...]
At the end of class on Friday Mr Willard left us with 5 questions regarding global climate change. These questions were as follows: 1. Is the Earth warming? 2. If so, is this warming unnatural? 3. If it is unnatural, is it anthropogenic (human-caused)? 4. What might happen as a result of this climate change? [...]
Last Friday, we discussed the origins of global warming. However, climate change is a more accurate term since some regions are cooling, not warming. First off, it must be established that not all greenhouse gases, like water vapor, CO2, CH4 and N2O are “bad.” In fact, without the natural greenhouse effect earth would be very [...]
In class, we dicussed what made up “good air” and how it was defined. First things first, we talked about how in Environmental Science, we mostly focus on the troposohere and the stratosphere. There are several differences between the two, but they both hold very important roles in providing “good air” Trophosphere vs. Statosphere Trophosphere [...]
