Is there evidence?

So we must have some form of evidence to show the effects of this monster "Climate Change".
So I will try to explain this to you as best I can...
Based on the notes posted by my colleague Adam, it is evident that there are effects of global warming on the ocean. In our particular area there are some issues that are more prominent than others and therefore those will be discussed using graphs where necessary. The main effects of climate change on Race Rocks are sea temperature, air temperature, salinity of water and rainfall.

Salinity of Water

This graph shows that there has not been much change in the salinity of water, but for certain months there have been small decreases this is accurate when compared to previous research by Adam and literature found.

Air TemperatureThe graph compares the average temperature of the month of July from 2006 to 2009. From the graph it can be seen that there is a decrease in temperature but this cannot be used as accurate evidence as it is covers a short amount of time and does not agree with literature, but it is important to note that there is a trend.

Rainfall
According to Adam’s research and literature it is said that there is expected to be a decrease in rainfall, this graph provides evidence that this decrease is currently happening. Between 2006 and 2008 the rainfall dropped by nearly 100 millimeters. This decrease will have consequences for wildlife which Ashley will discuss.

Sea Temperature


The graph above shows that the temperature of the ocean has been decreasing as a result of climate change. With the ocean becoming colder this causes problems for wildlife, which will be discussed later.
