Preparation Questions(Spring 2017)
Preparation Questions will be posted here for each class – you are responsible for answering them and writing out any questions that you have on the readings of course material. The answers can be found in the readings and/or on the web. I may gather these as a quiz occasionally.
Here is the ppt that we used for the exam review.
For the week of 30 April:
1 – Go over the Cz cooling – what caused the cooling?
2 – Who is James Hansen? and what has he written.
3 – What a fast and slow feedbacks?
4 – About 50 million years ago CO2 may have been about 1000 ppm – what was the world like then?
For the week of 24 April:
1 – Presentations – upload to dropbox before class.
2 – The teams doing LOI organize is and plot is up we will put it all together on Monday.
3 – The Science March was good.
4 – Climate Models is on the list as is ENSO. What is ENSO?
5 – Hadley cell expansion – read about it here.
For the week of 17 April:
We will be leaving at 11 am on Monday 17 April for the Byrd Polar Research Center – you will need to bring your own grub (lunch). On Friday 21 April is the day your project is due. 22 April is the Science March downtown Wooster at 2 pm – at 3pm on that day there will be a discussion about Climate Change.
The Radiocarbon Dates are in – Here they are.
For the week of 9 April:
The reading this week is here. It is a youtube video by Jim White the director of the Institute for Arctic and Alpine Research. Listen to it and write down any questions you have.
1 – What are the records White calls on to illustrate potential changes in future sea level.
2 – In class we have gone over the millennial-scale variability in the Holocene – now we will discuss a bit about century-scale and decadal viability.
3 – The Little Ice Age and the Medieval Warm Period are part of the discussion. What and when are these?
4 – What are the forcings for the LIA and MWP?
For the week of 3 April:
Readings: Bond et al. 2001 – in the readings section. Watch some of the Climate Change hearings in congress that took place last week. The Bond reading gives us some idea of the possible structure of the climate during the Holocene. The Climate Change Hearings gives us some insight into the politics of climate change.
For Bond et. al.
1 – What drives the millennial-scale pace of the Holocene?
2 – What are the records that Bond et al. use in this study?
3 – Who are the four scientists in the Climate Hearing last week? Look them up on the web.
4 – How representative of the global science community involved with climate change do you think these four scientists are?
5 – Many scientists over the past week have received literature from the Heartland Institute questioning the science of climate change – who is the Heartland Institute? One website that I recommend as a resource on Climate Change issues is Realclimate.org.
For the week of 27 March:
1- Read Bond et al (2001) reading 16 n the readings page.
2 – Come up with some questions about it – we will have a quiz on it on Friday and a discussion on Wed.
3 – What is the pace of the Holocene and what forces climate variability on this millennial time scale?
For the week of 6 March:
1 – Become familiar with the the last glacial transition; Define: The Younger Dryas, the Bolling Allured, The Older Dryas, the LGM, what are these and what do they tell us about the world going from the glacial to the interglacial?
2 – Outline the possible sequence of events that forces Ice Ages.
3 – How might the Younger Dryas occurred?
For the week of 27 February:
1 – The Osgood talk is Wednesday evening at 7:30pm (Lean Lecture Hall). Contemporary sea level rise is the topic.
2 – Have your core ready to go and we will get the Tracy House dated. Some of the reports from previous dating projects can be found here.
3 – Why do we say we live in an Ice Age World?
4 – What is Specmap?
5 – How do stable oxygen isotopes measured in forums tell us about ice volume?
6 – How does the tectonic carbon cycle serve as a thermostat for Earth’s climate?
For the week of 20 February:
1 – How can we sample trees and determine the recruitment date?
2 – Why are we doing this at the bog?
3 – What can the oak trees tell us about climate and disturbance?
4 – When was the Cenozoic and what was the overall climate and how do we know this?
5 – When I say – we live in an Ice Age world what do I mean?
6 – What are Milankovich cycles?
For the week of 13 February:
1 – Exam Friday – be sure to study.
2 – What are the principles of tree-ring analysis?
3 – How are radiocarbon ages calibrated and why?
4 – How to the fields of tree-ring dating and radiocarbon analysis mesh?
For the week of 6 February – see the questions below:
1 – What is an isotope – name the stable and radiometric isotopes of carbon. What is the atomic makeup of these?
2 – How does radiocarbon dating work?
3 – What is the Suess effect?
4 – Why are radiocarbon dates calibrated?
For the week of 30 January – see the questions below:
1 – Dr. Robert Musil will join us Monday – author of “Hope for a Heated Planet – this is a good video of him discussing his book.
2 – What is the modern carbon cycle and how does it differ from the tectonic of geologic carbon cycle? What carbon cycles have you learned about in other classes and how do these fit with our discussion?
3 – Who was Charles Keeling and what is the Keeling record (aka, Mauna Loa Record)?
4 – Here is the website I look at carbon dioxide in the ATM.
For the week of 23 January – see the questions below:
1 – What is a mean and what is a standard deviation?
2 – Why does the atmosphere circulate?
For Friday (20 January) – We will introduce the Earth’s NRG (NRG=energy) balance. NASA has a nice treatment of the Earth’s Energy Budget. Note is is often also referred to as the Earth’s Energy Balance.
1 – Why is it called a balance?
2 – What exactly is the Greenhouse Effect? List the top 5 GHGs.
3 – What is Latent Heat? What is sensible heat?
4 – What is long-wave and short-wave radiation?
5 – Why do I refer to this class as Climate Change? Why not Global Warming? What is the difference?
