From Reptiles, The Conservation Status Of The World's Snakes

As the Trump administration announces they will rollback Obama’s regulations to improve fuel efficiency and reduce greenhouse gas pollution from cars, a reminder that, as Vox’s Brad Plumer reported back in June:

For the first time since 1979, America’s cars, trucks, and airplanes emit more carbon dioxide than its power plants do... The story here is that the United States has made remarkable progress in greening its electricity sector since 2005. Whenever you see exciting headlines about renewable energy growth or the plunge in US emissions, those articles are usually talking about electricity.But power plants are only one-third of America’s CO2 emissions. Transportation, another third (and now the biggest source), remains tougher to address. In fact, since 2013, transport emissions have been creeping upward again.

The Regional Greenhouse Gas Initiative (RGGI) is a cap and trade program involving nine northeastern states:  Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island and Vermont. New Jersey was a part of the program but Gov. Christie pulled the state out of the agreement in 2011. The purpose of the program is to lower emissions from power plants in the northeast. On its face, carbon emissions have declined from 188 million tons of carbon-dioxide in 2005 to 91 million tons in 2012. However, much of that is due to the recession and cheap natural gas replacing dirty coal. At present, power plants emit less carbon than the current cap. This gives little incentive for them to invest in energy efficiency and renewable energy.

In an effort to further drive investment in efficiency and renewables, the RGGI released a proposal to progressively lower the emissions cap through 2020. The 2020 cap will be 14% below the current level of emissions.

Brad Plumer of the Washington Posts notes that "Between now and 2020, the new RGGI scheme is hoping to cut annual emissions by about 13 million tons. That’s about 0.06 of all power plant emissions in the United States last year. A rounding error. Ultimately, RGGI might best be thought of less as a solution to climate change and more of a revenue-raiser for the Northeast. It’s also an experiment of sorts — a way for policymakers to figure out what works and what doesn’t in climate policy." 

44% of crocodilians are threatened according to the IUCN. The Chinese alligator, Orinoco crocodile, Phillippines crocodile, Cuban crocodile, Siamese crocodile and Gharial are all considered critically endangered. A conservation success story, the American alligator, once facing extinction, is now considered "low risk", although the American crocodile is "vulnerable".

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

This graph is pretty self-explanatory. See the article from the Atlantic for further explanation of why natural gas is overtaking coal.

I'm back...

I apologize for my 5 months hiatus. I intend to divert my attention back to Envirographs, to continue using graphs and maps to explore environmental problems, trends and solutions.
