Oregon Falls Short on Greenhouse Gas Reduction 
The Oregon Global Warming Commission’s biennial report dropped recently, and the news isn’t encouraging. Oregon’s greenhouse gas production has risen over the last year, and looks unlikely to meet the 2020 targets for lowering. The Oregonian examines the situation and the options: https://www.oregonlive.com/politics/index.ssf/2018/12/with_emissions_on_the_rise_ore.html

Global Warming by the Numbers 
The BBC provides a set of seven charts which help to quantify the climate change conundrum. These graphics do a nice job of showing the links between causes and effects, on a global scale. https://www.bbc.com/news/science-environment-46384067

Freshwater Supplies Getting Contaminated With Salt 
The use of salt to de-ice has led to at least a third of American streams becoming saltier. Acid rain is contributing to the issue, forming salts when it interacts with minerals and construction materials. The problem is growing, threatening ecosystems, irrigators, and potable water supplies in much of the nation. Scientific American has the story: https://www.scientificamerican.com/article/freshwater-is-getting-saltier-threatening-people-and-wildlife/

Residential Batteries Not Meeting Potential 
An examination of the current state of affairs regarding the use of batteries to store energy at the home suggests that energy policies are largely to blame for the devices failing to cost-effectively reduce carbon emissions. In theory this off-grid storage could help to regulate demand, and reduce the carbon footprint of powering a home. In practice, implementing the batteries was found to actually increase emissions.

Western Monarch Populations Crash 
A variety of ills have plagued monarch butterflies in recent years, and this past year populations of the creatures plummeted by 86% from the previous year, begging the question if this might be the end. Here with the details of this dire news is Quartz: https://qz.com/1480192/monarch-populations-in-the-us-west-are-down-86-this-year/
