Q

What does Puetz et al. (2016) believe?

A

Most data regarding MC’s are ‘tuned’ - reducing reliability and highlighting researcher bias and reliance on age-models used.

Q

What does Ruddiman (2001) believe is the cause for the transition from 41kyr to 100kyr glaciation cycles ~900kyr ago?

A

Change in ice sheet boundary conditions, so only very favorable combinations or orbital parameters resulted in ice sheet growth.

Q

Who believes the beginning of the Anthropocene coincides with a peak in global 14C (thus a change in stratigraphic deposits)?

A

Lewis & Maslin (2015)

22
Q

When does Stuart et al. (2014) suggest the Anthropocene begun?

A

1610: The Orbis Spike - the first ‘meeting’ of Old and New worlds, which catalyzed CO2 reductions due to population shrinkage (due to disease, conflict) and reductions in farming and regrowth of trees.

23
Q

Who developed the Early Anthropocene Hypothesis?

A

Ruddiman et al. (2005)

24
Q

What did Tzedakis et al. (2012) find?

A

No glacial phase is expected in the next 1500 years due to current high levels of CO2

25
Q

What were the main findings of Ganopolski & Rahmstorf (2001)’s model results when testing for sensitivty of MOC?

A

~ Interglacials require LARGE changes to switch the MOC off
~ Large freshwater flux increase makes NADW formation drop to 0
~ Once MOC is in ‘off’ mode, FW input must very substantially reduced before it restarts
~ The MOC is a ‘bistable’ system

26
Q

What were the main findings of Ganopolski & Rahmstorf (2001)’s model when forced with FW flux changes?

A

~ NADW formation decreases with increased FW flux
~ Greenland temperature increases
~ North Atlantic SST decreases

27
Q

What does Alvarez-Solas et al. (2013) suggest?

A

Ocean circulation changes are responsible for Heinrich events.

28
Q

What did Heinrich (1988) find?

A

6 distinct peaks in Ice-Raft Debris during the last glacial, coincident with periods of low SST.

29
Q

Who suggested that oceanic absorption of CO2 may result in larger pH changes over the next several centuries than any found in the geological record (300 million years)?

A

Caldeira & Wickett (2003)

30
Q

What does Rhein et al. (2013) suggest?

A

Ocean warming accounts for 93% of total increase in Earth’s energy storage 1971-2010
