Predicted Land Change Along The Louisiana Coast Over The Next 50 Years If We Do Nothing More Than We

Carbon dioxide emissions in the UK are falling. CO2 emission fell 5.8% in 2016 from the previous year. Current emissions represent a 36% reduction from 1990 levels, and are at their lowest level since 1894 (outside the 1920s general strikes).

Why? The decline of coal. Coal use in the UK has declined steadily from its peak in 1956, and has experienced a dramatic decline since 2012. Coal use in 2016 dropped 52% from 2015.

The reduction in coal use is a result of multiple factors. The biggest is the expanded use of natural gas and renewables displacing coal. Other factors include an overall reduction in energy demand, the closing of Redcar Steelworks in 2015, and the UK’s carbon tax.

Brad Plumer in the Washington Post explains a new study on the dramatic drop in carbon emissions in the U.S. over the past five years. This graph shows a hypothetical level of emissions that were projected based on trends from 1990-2005, compared to the actual level of emissions in 2012. It then breaks down the causes.

Plumer explains:

The recession and financial crisis, obviously, made a big difference. A weaker economy has meant less demand for energy — that was responsible for more than half the drop compared with business as usual.

Meanwhile, Houser and Mohan find the U.S. economy actually hasn’t become vastly less energy-intensive over time (the blue bar). Yes, overall efficiency has gone up — Americans are buying more fuel-efficient cars and trucks, etc. But the country is also no longer shedding manufacturing jobs as quickly as it was during the 1990s. So the amount of energy we use per unit of GDP has generally followed historical trends, improving only gradually.

The real change has come in the type of energy that the United States is using. The country is now relying more heavily cleaner forms of energy than it used to, and that explains about half of the fall in emissions

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

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.

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.

From Vox:

“In recent years, China, the world’s largest emitter of carbon dioxide, has been making major efforts to restrain its coal use and shift to cleaner sources of energy. When Donald Trump and other conservatives in the United States complain that China isn’t doing anything about climate change, they simply haven’t been paying attention...

Since 2013, China’s coal consumption has actually fallen — due in part to a major economic slowdown but also in part to sluggish output in heavy industries like steel and cement that have traditionally accounted for half the country’s coal use... On top of that, as China’s leaders start to take global warming seriously, the country has been making massive investments in clean energy. As part of the Paris climate deal, China has pledged to get 20 percent of its energy from low-carbon sources by 2030. The government is planning to install an addition 130 gigawatts of wind and solar by 2020 and making big bets on nuclear power.”

This is cool.

“About 3 billion people around the world  — mostly in Africa and Asia, and mostly very poor — don't have access to modern energy and still cook and heat their homes by burning coal, charcoal, dung, wood, or plant residue indoors. These homes often have poor ventilation, and the smoke can cause a horrible array of respiratory diseases, including lung cancer... Indoor air pollution gets surprisingly little attention for such a lethal public health problem. It kills more people each year than HIV/AIDS and malaria combined, but few countries treat it as a crisis on the same level.” - Vox
