Environment

Can you be liable for damages if you didn't mean to do it? Can the pollution laws of one country be enforced in another? When it comes to politics and the environment, laws really only count when they are on your side, as we saw when Germans ironically declared it wrong for an American to dump iron dust in the ocean for a geo-engineering experiment, yet the same loophole was completely ethical when they did it three years ago.
Greenland has areas of very clean water, the like of which just does not exist in developed nations, but also highly polluted water, making it an excellent location for studying the environmental impacts of chemicals

More than 10,000 tons of antibiotics are consumed in Europe each year and an estimated 30-60% of those pass through animals and humans completely unchanged. These different substances can then reach the ocean via hospitals, municipal sewage, fish farms and run-off from agriculture and landfills.

A research group from the University of Gothenburg wanted to examine the potential effects of accumulating antibiotics in the seabed, so off to Greenland they went.
A recent study published in Environmental Sciences Europe has attracted attention because it documents a net increase in pesticide use on genetically engineered crops in the US.  The author, Chuck Benbrook, is certainly qualified to consider pesticide issues, and I have had positive interactions with him over the years; however as an organic advocate he has a very different perspective on pesticides than I do.
A new study says that the use of herbicides in the production of three genetically modified herbicide-tolerant crops, cotton, soybeans and corn, has gone up rather than down. The counterintuitive estimate is based on an analysis of publicly available data from the U.S. Department of Agriculture's National Agriculture Statistics Service. 

Humans of the Upper Palaeolithic Age recycled and repurposed their stone artifacts to be put to other uses, according to a group of anthropologists after examining burnt artifacts found in the Molí del Salt site in Tarragona, Spain.

How could they make that determination? Finding that stone tools during prehistoric times were recycled is not going to be apparent in archaeological records.

James Madison - A Prescient President.

We are changing our planet's atmosphere.

It is widely known that G.S. Callendar warned of this in 1938.

It is virtually unknown that James Madison warned of it in 1818, in the form of a rhetorical question:
There are LEED-certified buildings and there are zero-energy buildings. And then there’s Villa Åkarp outside of Malmo, Sweden — an energy-plus residential home. In other words, a home that produces more energy than it uses.

Since construction was completed on the three-bedroom, two-bathroom house in 2009, it has raised the bar for what is possible in home construction. Villa Åkarp takes its design cues from the passive house, or Passivhaus, movement, a design program for creating super-insulated houses that rely on window orientation, thermal recovery and other elements for heating and cooling.

But Villa Åkarp ups the ante.
The EPA has declared water, the substance the Clean Water Act was created to protect, a pollutant - and it is getting the federal government dragged into court.
Climate change advocacy groups are not happy with U.S. Climate Envoy Todd Stern's recent statement at Dartmouth College renouncing a limit of 2 degree celsius (2C) temperature rise as a global goal for UN climate negotiations. Stern said that agreeing to a framework to achieve the 2C goal would "only lead to deadlock" and that a new agreement should give countries "flexibility."
