BBC claim of 2017 as hottest year ignores the facts

“One naturally has every right to be suspicious when supposedly honest and impartial “scientists” turn into activists for political change. It is not up to them to decide which courses of action it is right for societies to take.

But to the facts!

To start with, the claim that 2017 was not an El Nino year is simply not true.” click here

Paris March for Life Protest Against Abortion

Global warming slow down statistically significant

A transparent analysis for everyone to consider.

“The standard statistical test that I will be using to compare the warming rate to the average warming rate, will be the t-test. The warming rate for every possible 10 year interval, in the range from 1970 to 2017, will be compared to the average warming rate. The results of the statistical test will be used to determine whether each trend is a slowdown, a speedup, or a midway (statistically the same as the average warming rate). The results will be presented graphically, to make them crystal clear. All of the calculations for this article can be found at the end of the article.” click here


Cloud cover has cooling effect on climate models

“Princeton University researchers have found that the climate models scientists use to project future conditions on our planet underestimate the cooling effect that clouds have on a daily — and even hourly — basis, particularly over land.” click here

Susceptibility differs to the toxic effects of arsenic

Brenda C. Minatel1, Adam P. Sage1, Christine Anderson, Roland Hubaux, Erin A. Marshall, Wan L. Lam, Victor D. Martinez. Environmental arsenic exposure: From genetic susceptibility to pathogenesis. Environment International Volume 112, March 2018, Pages 183–197

More than 200 million people in 70 countries are exposed to arsenic through drinking water. Chronic exposure to this metalloid has been associated with the onset of many diseases, including cancer. Epidemiological evidence supports its carcinogenic potential, however, detailed molecular mechanisms remain to be elucidated. Despite the global magnitude of this problem, not all individuals face the same risk. Susceptibility to the toxic effects of arsenic is influenced by alterations in genes involved in arsenic metabolism, as well as biological factors, such as age, gender and nutrition. Moreover, chronic arsenic exposure results in several genotoxic and epigenetic alterations tightly associated with the arsenic biotransformation process, resulting in an increased cancer risk. In this review, we: 1) review the roles of inter-individual DNA-level variations influencing the susceptibility to arsenic-induced carcinogenesis; 2) discuss the contribution of arsenic biotransformation to cancer initiation; 3) provide insights into emerging research areas and the challenges in the field; and 4) compile a resource of publicly available arsenic-related DNA-level variations, transcriptome and methylation data. Understanding the molecular mechanisms of arsenic exposure and its subsequent health effects will support efforts to reduce the worldwide health burden and encourage the development of strategies for managing arsenic-related diseases in the era of personalized medicine.

A comparison of management strategies for trace organic chemicals in water

Bieber S, Snyder SA, Dagnino S, Rauch-Williams T, Drewes JE. Management strategies for trace organic chemicals in water – A review of international approaches. Chemosphere. 2017 Dec 16;195:410-426. doi: 10.1016/j.chemosphere.2017.12.100.

To ensure an appropriate management of potential health risks and uncertainties from the release of trace organic chemicals (TOrCs) into the aqueous environment, many countries have evaluated and implemented strategies to manage TOrCs. The aim of this study was to evaluate existing management strategies for TOrCs in different countries to derive and compare underlying core principles and paradigms and to develop suggestions for more holistic management strategies to protect the environment and drinking water supplies from the discharge of undesired TOrCs. The strategies in different industrial countries were summarized and subsequently compared with regards to three particular questions: 1) Do the approaches different countries have implemented manage all or only specific portions of the universe of chemicals; 2) What implementation and compliance strategies are used to manage aquatic and human health risk and what are their pros and cons; and 3) How are site-specific watershed differences being addressed? While management strategies of the different countries target similar TOrCs, the programs differ in several important aspects, including underlying principles, the balance between aquatic or human health protection, implementation methods, and financing mechanisms used to fund regulatory programs.
