This is a charade, right?

So let me guess. Ummm….blame it on Bush. Yea, that’s it. It is Bush’s fault.
The following summarizes the findings of this work (page viii, Figure 1):
Global climate models are unable to make accurate projections of climate even 10 years ahead, let alone the 100-year period that has been adopted by policy planners. The output of such models should therefore not be used to guide public policy formulation.
Neither the rate nor the magnitude of the reported late twentieth century surface 2000) lay outside the range of normal natural variability, nor were they in any way unusual compared to earlier climatic history.
Solar forcing of temperature change is likely more important than is currently recognized.
No unambiguous evidence exists of dangerous interference in the global climate caused by human-related CO2 emissions. In particular, the cryosphere is not melting at an enhanced rate; sea-level rise is not accelerating; and no systematic changes have been documented in evaporation or rainfall or in the magnitude or intensity of extreme meteorological events.
Any human global climate signal is so small as to be nearly indiscernible against the background variability of the natural climate system. Climate change is always occurring.
A phase of temperature stasis or cooling has succeeded the mild warming of the twentieth century. Similar periods of warming and cooling due to natural variability are certain to occur in the future irrespective of human emissions of greenhouse gases.

M Ryan, K Hamilton, M Hamilton, CN Haas. Evaluating the Potential for a Helicobacter pylori Drinking Water Guideline. Risk Analysis. 2014 Mar 24. doi: 10.1111/risa.12190.
Helicobacter pylori is a microaerophilic, gram-negative bacterium that is linked to adverse health effects including ulcers and gastrointestinal cancers. The goal of this analysis is to develop the necessary inputs for a quantitative microbial risk assessment (QMRA) needed to develop a potential guideline for drinking water at the point of ingestion (e.g., a maximum contaminant level, or MCL) that would be protective of human health to an acceptable level of risk while considering sources of uncertainty. Using infection and gastric cancer as two discrete endpoints, and calculating dose-response relationships from experimental data on humans and monkeys, we perform both a forward and reverse risk assessment to determine the risk from current reported surface water concentrations of H. pylori and an acceptable concentration of H. pylori at the point of ingestion. This approach represents a synthesis of available information on human exposure to H. pylori via drinking water. A lifetime risk of cancer model suggests that a MCL be set at <1 organism/L given a 5-log removal treatment because we cannot exclude the possibility that current levels of H. pylori in environmental source waters pose a potential public health risk. Research gaps include pathogen occurrence in source and finished water, treatment removal rates, and determination of H. pylori risks from other water sources such as groundwater and recreational water.
“In 2007, the IPCC predicted that rising global temperatures would kill off many species. But in its new report, part of which will be presented next Monday, the UN climate change body backtracks. There is a shortage of evidence, a draft version claims.”
