Would you drink water from under the Fukushima, Japan nuclear reactors?

Well, here is one Japan lawmaker who did….assuming the water has been properly decontaminated…..click here.

Chung and Räisänen 2011: Origin of the Arctic warming in climate models

Bottom line….the 2 climate models examined do not accurately represent climate forcings…..I’ve heard that somewhere before……click here and click here for further discussion.

Chung, C. E., and P. Räisänen (2011), Origin of the Arctic warming in climate models,  Geophys. Res. Lett., doi:10.1029/2011GL049816, in press

Abstract: There is a debate on whether the snow/ice change feedback or poleward energy transport from lower latitudes generates the observed Arctic warming amplification. There is another possibility that remotely induced warming in the Arctic can be amplified by snow/ice feedbacks. We demonstrate that this mechanism plays an important role in two independent climate models: CAM3 and ECHAM5. We also show with these two models that the June-August temperature structure in the vertical is a good indicator of how much the climate forcing from lower latitudes contributes to Arctic warming. Compared with the June-August 3D temperature trend in ERA Interim reanalysis, the CMIP3 models simulate warming at higher levels, suggesting that the models over-simulate the role of poleward energy transport in Arctic warming. This finding has implications for climate feedback and aerosol forcing.

 

Debate: Are overpopulation and climate a crisis?

In  certain locations, too many people in an area can cause localized problems….but worldwide population growth is not a crisis….even with 7 billion people…..

Berkeley, California climate analysis in disrepair

The claims of the BEST program at Berkeley are under scrutiny….well worth the reading…..click here and click here.

It seems that this group of scientists and those like it simply cannot sustain a rational discussion of the science underlying its claims…so it goes to the press first…forget peer-review…

To examine the long-term infectivity of human norovirus in water, 13 study subjects were challenged at different time points with groundwater spiked with the prototype human norovirus, Norwalk virus. Norwalk virus spiked in groundwater remained infectious after storage at room temperature in the dark for 61 days (the last time point tested). The Norwalk virus-seeded groundwater was stored for 1,266 days and analyzed, after RNase treatment, by reverse transcription-quantitative PCR (RT-qPCR) to detect Norwalk virus RNA contained within intact capsids. Norwalk virus RNA within intact capsids was detected in groundwater for 1,266 days, with no significant log10 reduction throughout 427 days and a significant 1.10-log10 reduction by day 1266. Purified Norwalk virus RNA (extracted from Norwalk virus virions) persisted for 14 days in groundwater, tap water, and reagent-grade water. This study demonstrates that Norwalk virus in groundwater can remain detectable for over 3 years and can remain infectious for at least 61 days.
