Oyster reefs are in rough shape over much of the world, threatened by over-harvesting in combination with pressures from exotic species (including disease) and pollution. This means those coastal areas are losing the valuable ecosystem services, such as water filtration and protection from storm surges, oyster reefs provide.

While the average household today consists of fewer people than 60 years ago (2.55 people vs. 3.37 people), the average house size has increased by over 150%. Bigger houses (despite smaller families) means more energy used to heat and cool, more land cleared to build, and more materials required for construction.

A lacy, cloud-like pattern drifting across a Denver-area radar screen turned out to be a 70-mile-wide (110-kilometer) wave of butterflies, forecasters say... An unusually large number of painted ladies, which are sometimes mistaken for monarch butterflies, has descended on Colorado’s Front Range in recent weeks, feeding on flowers and sometimes flying together in what seem like clouds.

The reduction in CO2 emissions from the energy sector in the U.S. over the past 5 years (see previous post) was due in large part to a reduction in emissions from coal. In 2009, the financial collapse led to diminished use of all fuel sources and greenhouse gas reductions across the board. Since then, the expanding use of natural gas has increased it's carbon footprint, but the decline in the use of coal and the subsequent decrease in greenhouse gas emissions associated with coal is remarkable. Coal is the most carbon-rich fossil fuel, so any declines from that source is good news for the climate.

...and lizards, a quarter of which are threatened.

The species groups that are proportionally most in danger (the proportion of species within that grouping that are imperiled) are overwhelmingly freshwater species. Freshwater mussels, crayfishes, stoneflies (stonefly larvae live in freshwater), freshwater fishes and amphibians are the most at risk. This demonstrates the substantial need for a focus on conservation of freshwater habitats.

Let's look at the false choice too often portrayed in the media and by politicians of jobs vs. the environment in the context of mountaintop removal mining (MTR). Coal companies claim that any efforts to stop or restrict MTR will cost jobs and devastate economies in Appalachia. Yet, the graph above shows that as coal production has increased, employment of coal miners has decreased. This is because MTR replaces coal miners with big machinery and explosives. The reason coal companies like it is because it increases profits, in part by decreasing labor costs. Thus, it is MTR, not efforts to protect the environment by restricting MTR, that is destroying jobs in the mountains of Appalachia

From Bloomberg:

Coal, the most polluting fuel that was once the world’s fastest growing energy source, has been a target of countries and companies alike as the world begins to work toward the goals of the Paris climate agreement. Consumption is falling as the world’s biggest energy companies promote cleaner-burning natural gas, China’s economy evolves to focus more on services than heavy manufacturing and renewable energy like wind and solar becomes cheaper.

Global consumption dropped 1.7 percent last year compared with an average 1.9 percent yearly increase from 2005 to 2015, according to BP. China, which accounted for about half of the coal burned in the world, used 1.6 percent less of the fuel, compared with an average 3.7 percent annual expansion in the 11 preceding years.

Good read by Brad Plumer on the recent drop in China’s CO2 emissions.

On the two year anniversary of the Deepwater Horizon oil spill in the Gulf of Mexico, it's worth putting the size of that spill into context. By the time it was capped on July 15, 2010, the well had released 4.9 million barrels of oil into the Gulf, making it the largest accidental oil spill in history.
