Average Annual Net Loss And Gain Of Wetlands In The Lower 48 States Of The U.S. Wetlands Protection Regulations

In a report Tuesday, Environment and Climate Change Canada said the 51 separate herds [of boreal caribou] across the country remain under pressure from human and natural disturbances to their habitat more than five years after the federal and provincial governments concluded a protection agreement.

The range of the boreal caribou extends across the country from Yukon to Labrador, but its forest habitat has been increasingly disturbed by industrial activity such as forestry, mining and oil and gas development, as well as by forest fires, the spread of pests and other impacts of climate change.

A recent study looked at the demographics of an elephant population in Samburu, Kenya, and the impact of poaching. This graph shows the annual PIKE, or Proportion of Illegally Killed Elephants. PIKE is calculated as the number of illegally killed (poached) elephant carcasses divided by the total number of elephant carcasses discovered that year. The graph shows a recent dramatic increase in poaching.

The authors state:

Illegal human killing caused over half the recorded mortality in the Samburu elephants over the age of 9 (and indirectly caused the deaths of all victim’s dependent calves under 2 years). The high illegal killing in the latter part of the study had serious ramifications for the structure and organization of the population... the illegal killing appeared to select adult individuals in Samburu and particularly males resulting in increasing skew in the sex ratio over the course of the fourteen year study. Social disruption also resulted, with numerous well known and stable family groups being completely lost (i.e. no surviving breeding females) causing increased numbers of unaffiliated juveniles (orphans)

According to the New York Times, the recent spike in poaching, the greatest in decades, is driven by rising demand for ivory in Asia.

From National Geographic:

Four national monuments in the American West could be shrunk and six others opened up to permit more mining, grazing, logging, and commercial fishing if President Trump follows the recommendations of Interior Secretary Ryan Zinke...

If enacted, the modifications would represent the most sweeping changes to existing national monuments by any sitting president — and are sure to set off a legal battle over presidential powers likely to reach the U.S. Supreme Court.

Here are the threatened monuments:

Facing size reduction: 4. Cascade-Siskiyou, Oregon/California 12. Gold Butte, Nevada 13. Grand Staircase Escalante, Utah 14. Bears Ears, Utah

Facing management changes (mining, grazing, logging, fishing): 20. Organ Mountains-Desert Peaks, New Mexico 21. Rio Grande del Norte, New Mexico 22. Katahdin Woods and Waters, Maine C. Pacific Remote Islands, south of Hawaii  D. Rose Atoll, by American Samoa E. Northeast Canyons and Seamounts, off the coast of Massahcusetts

As wold population increase following grey wolf reintroduction to Montana, Wyoming, and Idaho, ranchers have become the wolves’ greatest antagonist, blaming them for killing their livestock. But coyotes are the primary source of livestock loss, and wolves can help drive coyotes out of areas.

California's climate change law (AB 32), which puts a price on carbon emissions and creates a cap-and-trade system to reduce greenhouse gas emissions, is yielding substantial reductions in emissions from oil refineries. These refineries are a major source of carbon emissions, along with a host of other toxic chemicals like ammonia, lead, benzene, mercury and acid gases.

Data from the California Air Resources Board shows that 11 refineries substantially reduced emissions between 2010 and 2011, in addition to cuts in the release of other toxic pollutants. Evidence shows that these reductions not a result of cuts in production, but to refineries investing in and upgrading equipment in response to AB 32. An example is Valero’s refinery in Benicia, CA, which decreased covered emissions by over 95,000 metric tons, while also cutting ammonia emissions by 98%, sulfuric acid by 84%, and benzene by 49%, through the installation of a new flue gas scrubber.

Acid rain (wet sulfate deposition = sulfuric acid rain) before (89-91) and after (07-09) the Clean Air Act Amendments of 1990, which used a cap & trade program to limit sulfur dioxide emissions. For anyone who has any doubt that environmental regulations can work...

Meanwhile, as coal's share of U.S. electricity production declines, wind power capacity has been increasing. By the end of 2010, total wind power capacity exceeded 40,000 megawatts, representing a cumulative investment total of $78 billion since the beginning of the 1980s.

*the slowed growth observed in 2010 is attributed to the delayed impact of the global financial crisis (which impacted the apparent availability of capital for 2010 projects that were being planned in 2009), low natural gas prices and a lower overall demand for energy

From The Guardian:

In the past two decades, 10% of the earth’s wilderness has been lost due to human pressure, a mapping study by the University of Queensland has found... These pristine wild places exist in inhospitable locations: the deserts of Central Australia; the Amazon rainforest in South America; Africa; the Tibetan plateau in central Asia; and the boreal forests of Canada and Russia. They are being encroached on by logging, oil and gas exploration, mining, roads and agriculture.

This map traces the ideal deployment of solar energy plants in the Sahara Desert to generate electrical power for the world's population. It might not look like a lot, but there are some major caveats here. For one, this map seems to assume 100% efficiency. In reality, current solar panel technology is only able to capture around 20% of solar energy, even in the desert. So the 254-by-254 kilometer area in the Sahara Desert that could theoretically absorb enough rays to power the entire world would have to be five times larger. Second, large amounts of electric power are lost over large transmission distances, meaning that a single power plant could never really power the entire planet.

Still, this map is a good illustration of how little space would be needed to power the entire planet. According to May, some 3.49 million square kilometers are available for solar thermal power facilities in Morocco, Algeria, Tunisia, Libya and Egypt alone. Worldwide, the potential high-energy solar sites far outstrip any plausible need.
