The Climate has been Changing Since the Earth was Formed

Richard S. Lindzen:

“Research in recent years has encouraged those of us who question the popular alarm over allegedly man-made global warming. Actually, the move from “global warming” to “climate change” indicated the silliness of this issue. The climate has been changing since the Earth was formed. This normal course is now taken to be evidence of doom.” click here

Battery Park Sea Level Rise 0.93 ft per 100 Years

Expensive modeling studies are not necessary in order to plan responsibly for the future. In many cases studies such as this are a waste of time and money. New York’s skyline will always be changing. The report writers have simply ignored science and are relying on assumptions and speculations.

The mean sea level trend is 2.83 millimeters/year with a 95% confidence interval of +/- 0.09 mm/yr based on monthly mean sea level data from 1856 to 2013 which is equivalent to a change of 0.93 feet in 100 years.

“New York City Panel on Climate Change released a new report detailing exactly how climate scientists expect New York City to change over over the next 100 years, focusing on projected increases in temperature and sea level. Sea level rise will certainly transform the shape of the city’s coastline. But Manhattan’s edges are basically a man-made pile of garbage already—they can go ahead and disintegrate. What climate will really change is the true shape of New York: Its iconic skyline, and the buildings in it.” click here

Sinkhole Threatens to Swallow Washington, DC

“A huge sinkhole that nearly swallowed a truck appeared in the streets of northeastern Washington D.C. in the late afternoon on Tuesday. D.C. Water spokesman reported that the sinkhole that—nearly as large as both lanes of the road on 13th Place NE near Farragut Place and Faraday Place—was caused by a water main break that undermined the integrity of the ground underneath the road.” click here

Phthalates in the Environment

Net S, Sempere R, Delmont A, Paluselli A,Ouddane B. Occurrence, fate, behavior and ecotoxicological state of phthalates in different environmental matrices. Environ Sci Technol. 2015 Mar 2. 

Because of their large and widespread application, phthalates or phthalic acid esters (PAEs) are ubiquitous in all the environmental compartements. They have been widely detected throughout the worldwide environment. Indoor air where people spend 65-90% of their time is also highly contaminated by various PAEs released from plastics, consumer products as well as ambient suspended particulate matter. Because of their widespread application, PAEs are the most common chemicals that humans are in contact with daily. Based on various exposure mechanisms, including the ingestion of food, drinking water, dust/soil, air inhalation and dermal exposure the daily intake of PAEs may reach values as high as 70 µg/kg/day. PAEs are involved in endocrine disrupting effects, namely, upon reproductive physiology in different species of fish and mammals. They also present a variety of additional toxic effects for many other species including terrestrial and aquatic fauna and flora. Therefore, their presence in the environment has attracted considerable attention due to their potential impacts on ecosystem functioning and on public health. This paper is a synthesis of the extensive literature data on behavior, transport, fate and ecotoxicological state of PAEs in environmental matrices: air, water, sediment, sludge, wastewater, soil and biota. First, the origins and physicochemical properties of PAEs that control the behavior, transport and fate in the environment are reviewed. Second, the compilation of data on transport and fate, adverse environmental and human health effects, legislation, restrictions and ecotoxicological state of the environment based on PAEs is presented.

Disinfection By-Products in Pakistan Drinking Water

Abbas S, Hashmi I, Rehman MS, Qazi IA, Awan MA, Nasir H. Monitoring of chlorination disinfection by-products and their associated health risks in drinking water of Pakistan. Journal of Water and Health. 2015 Mar;13(1):270-84. doi: 10.2166/wh.2014.096.

This study reports the baseline data of chlorination disinfection by-products such as trihalomethanes (THMs) and their associated health risks in the water distribution network of Islamabad and Rawalpindi, Pakistan. THM monitoring was carried out at 30 different sampling sites across the twin cities for 6 months. The average concentration of total trihalomethanes (TTHMs) and chloroform ranged between 575 and 595 μg/L which exceeded the permissible US (80 μg/L) and EU (100 μg/L) limits. Chloroform was one of the major contributors to the TTHMs concentration (>85%). The occurrence of THMs was found in the following order: chloroform, bromodichloromethane > dibromochloromethane > bromoform. Lifetime cancer risk assessment of THMs for both males and females was carried out using prediction models via different exposure routes (ingestion, inhalation, and dermal). Total lifetime cancer risk assessment for different exposure routes (ingestion, inhalation, and skin) was carried out. The highest cancer risk expected from THMs seems to be from the inhalation route followed by ingestion and dermal contacts. The average lifetime cancer risk for males and females was found to be 0.51 × 10(-3) and 1.22 × 10(-3), respectively. The expected number of cancer risks per year could reach two to three cases for each city.
