This is the handout which I was suppposed to pass around at the meeting on the 4th of Feb.
New Papers & Articles Published from 01/27/2013 to 02/03/2013
Nature (News) Volume 493 (01/31/2013)
(1) Obama rekindles climate hopes doi:10.1038/493590a
* Obama’s administration is expected to impose two greenhouse gas related regulations. He described global warming as betraying our children and future generations if we failed to address this. A very impressive speech as always!
Nature (Features)
(2) Caught in the act doi:10.1038/493592a
* Challenging concepts about the solar system was introduced. For example, Saturn’s rings could be younger than we believed and lo (one of Jupiter’s moons) is more volcanically active than we assumed.
Nature (News & Views)
(3) Solar physics: The planetary hypothesis revived doi:10.1038/493613a
* Abreu et al. believe that small changes in the Sun’s internal structure due to external torque can alter magnetic field strength thus modulating the flux of cosmic rays reaching to Earth. Whether it is wrong or right, we, paleoclimatologists must pay close attention to his research as it highly affects the logic of radio isotopes...
(4) Biogeochemistry: The depths of nitrogen cycling doi:10.1038/493616a
* Dissolved organic carbon (DOC) was believed to be broken down in surface waters, but Letscher and his co-workers' experiments revealed that DON is mineralized three times faster in the upper mesopelagic zone. Thus, they suggested a two-step process that occurs in the lower euphotic and mesopelagic zone.
Nature (Letter)
(5) Divergent global precipitation changes induced by natural versus anthropogenic forcing
Liu et al.
doi:10.1038/nature11784
* Their climate model showed the outcome of warming is different in the tropical Pacific: the sea surface temperature gradient increases due to solar radiation, and it decreases due to green-house gas forcing. This difference is related to the magnitude of tropospheric cooling. This topic will be highly related to my mid-Holocene SST research in the tropics!
(6) Deep instability of deforested tropical peatlands revealed by fluvial organic carbon fluxes
Moore et al.
doi:10.1038/nature11818
* Indonesia is a globally significant source of atmospheric carbon dioxide, and the article estimated the impact of peatland to carbon flux.
Science (NewsFocus)Volume 339(02/01/2013)
(7) Tight budget squeeze European earth observation doi:10.1126/science.339.6119.504
* Bad news for climate researchers? European Space Agency needs to cut down budget for earth observation to make room for International Space Station.

Science volume (Reports)
(8)Carbon cycle makeover D.E.Canfield and L.R.Kump doi:10.1126/science.1231981
* They explained the paper (11) with easier terms: did we misinterpret the extreme value of carbon isotope? The lower level of oxygen could have boosted the alkalinity with we used to interpret as the increase of high organic carbon burial.
(9) Detecting ozone and greenhouse gas driven wind trends with observational data
doi: 10.1126/science.1225154
* Antarctic ozone depletion and greenhouse gas shifted the easterly jet polewards during austral summer. As a result, locations of storms and carbon uptake in the Southern Ocean are altered.
(10)Recent changes in the ventilation of the Southern Oceans
D.W. Wough et al
doi: 10.1126/science.1225411
* CFC-12 was used to investigate the ventilation of Southern Oceans from 1990 to 2000. The result suggested an increase of the age of circumpolar deep waters due to the formation of ozone hole.
(11) Authigenic Carbonate and the History of the Global Carbon Cycle
Schrag et al
doi: 10.1126/science.1229578
* The extreme carbon values during Proterozoic, Paleozoic and Triassic may be explained by authigeneic carbonate produced in sediment pore fluids.
PNAS (Commentary)Volume 110 (01/29/2013)
(12) Coral calcification feel the acid doi:10.1073/pnas.1221308110
* This is the topic I will engage for my dissertation. What really matters to corals is not ocean acidification but the impact of ocean acidification to coral calcifying fluid.
(13) Legacy of a half century of Athabasca oil sands development recorded by lake
ecosystems
J. Kurek et al doi:10.1073/pnas.1217675110
* Lake sediments helped the absence of environmental monitoring in Canada’s significant oil reserves. The sediments core revealed that the level of PAH is strikingly high due to oil production.
(14) Filling the Eastern European gap in millennium-long temperature reconstructions
U. Buntgen et al doi:10.1073/pnas.1211485110
*545 tree ring samples were compiled to reconstruct temperature changes in Eastern Europe. Plague outbreaks and political conflict coincided with temperature depressions. This paper also pointed out a risk of temperature reconstruction due to individual weighted samples.
(15) SLC4 family transporters in a marine diatom directly pump bicarbonate from
seawater
Nakajima et al doi/10.1073/pnas.1216234110
*To quantify bicarbonate flux to diatoms is very important to estimate carbon dioxide concentration system in surface waters. They successfully identified the bicarbonate transporter of P. tricornutum.
