Document Summary

there will be a tutorial on thursday. i taped a video: john magnasan gave a lecture and he lectures about fresh water and global change. I watched the first 10 minutes and brendan will present it. Some of the arguments he makes are very good. He is a good scientist, highly specialized, and he will talk about what i am talking about today. you have a paper to discuss as well. Last day i talked about the implications of climate change and how the biological communities at a whole range were being affected. I am just touching the surface of literature that is coming out on this subject. There was a journal last week on animal ecology. There are thousands coming out every year on this topic. I will get to that example in a minute. A fact usually downplayed in the discussion of responses to global warming is the tendency for evolutionary changes to occur.

As you may know, the causes of global warming and climate change are debated in scientific circles. Some say greenhouse gases are to blame; others say the earth regularly experiences cycles of warming and cooling. Some point to our recent record cold temperatures and snowfall, and ask how can we blame global warming? Still other scientists are predicting that our present global warming trend will result in a new Ice Age.

Try to locate the physics principle(s) which provide a logical progression from warmer temperatures to an Ice Age. You don't have to believe the theory, just merely repeat it here and discuss its merits or deniability.

Need answer for this and it has must be 250 words and the answer must relate to the question. Please also reference any sources (quotes) you use at the end of your response.

1. The hydrologic system purifies water in nature. Find way that humans mimic this system to purify the water that we use.

2. We hear a lot about climate change and global warming. Do some research on how global warming is affecting the glaciers present today and how that can affect us now and in the future.

3. How could scientists have found similar life forms from the same Mesozoic era on different continents.

4. What is the Ring of Fire? Where is it located and why is it the way it is?â

5. A volcano is a natural occurrence and generally thought of as a disaster. How can volcanos be good for people?

6. Catastrophism was the prevailing theory as to why the earth looked like it did in the 1600âs and 1700âs. Talk about what the theory was, why it was popular and why we know better today.

7. Why is global warming affecting the salinity of the worldâs oceans and why is this important. What effects does this have?

8. Humans, including myself, love the beach. Most people dream of having a house right on the water. However with the shore being such a dynamic, changing environment this isnât always such a great idea. Talk about some of the lengths humans go to to preserve their costal properties and communities.

9. Please discuss the depletion of our ozone layer. Why we should care, what is causing it and what can we do to stop it?

10. Water is a huge part of our atmosphere and the cause all of our precipitation. Describe the weather in your area today or in this season and describe the science behind the weather and what is happening in the atmosphere around you. Example: humid, dry, raining, snowing, sleet, freezing rain, fog, hail.

You have been hired by Mike Sweeney, the Executive Director of TNC California to develop an executive report for him to present to his board help inform them about climate change and the marine environment for the state of California. He wants the report to provide a clear direction of what TNC California should be doing about climate change in the marine environment in California. Therefore, this summary must include the following:

- if you may please answer in an outline format and an implication of the following instructions will be greatly appreciated!!!!

A summary of the basic mechanism of global warming, including the primary greenhouse gases and their anthropogenic (human-produced) sources.

A review of the important likely (i.e. supported by the scientific literature) physical impacts that these global changes will cause to the marine environment at the regional level of the State of California.

A review of the important likely (i.e. supported by the scientific literature) ecological impacts that these global changes will cause to the marine environment at the regional level of the State of California.

A description of feasible and effective actions that the State of California is currently taking to mitigate greenhouse gas emissions.

A description of feasible actions that the State of California should undertake to enhance the resiliency of marine resources to climate change.

A review of critical knowledge gaps (what we need to know and understand) in our ability to understand and address climate change impacts in Californiaâs marine environment.
