Environmental Rules Played Minor Role in Coal’s Decline

Environmental Rules Played Minor Role in Coal’s Decline

Environmental and climate regulations that cut pollution from coal-fired power plants have played only a minor role in the decline of the coal industry, which has been hurt mainly by expanding use of natural gas and less demand for electricity, according to a Columbia University report published this week. U.S. coal use fell by about 30 percent … Read More

How Trump’s Monuments Review Could Impact Climate

How Trump’s Monuments Review Could Impact Climate

President Trump has directed the Interior Department to “review” all large national monuments created since 1996 to recommend ways for Congress to shrink or abolish them. The directive came in the form of an executive order signed by the president Wednesday morning. It requires the department to make preliminary recommendations within 45 days and … Read More

Pollution From Canada’s Oil Sands May Be Underreported

Pollution From Canada’s Oil Sands May Be Underreported

Canadian scientists have found that the standard way of tallying air and climate pollution from Alberta’s oil sands vastly understates pollution levels there — by as much as 4.5 times, according to a Canadian government study published Monday. The study shows that air samples collected using aircraft may be a more accurate way to tally air and … Read More

100 Days of Climate: Week 14

Addressing climate change using sound science is crucial not just for the U.S., but for the world. Unfortunately, that appears unlikely over the next four years under the Trump administration, which has shown signs of being apathetic if not outright hostile to climate science and science-based policies to rein in carbon pollution. Trump has… Read More

A Cooler Future May Hinge on Removing CO2 From the Air

A Cooler Future May Hinge on Removing CO2 From the Air

Climate pollution equal to about 27 times humans’ 2015 carbon dioxide emissions may have to be removed from the atmosphere and locked underground forever in order to keep the globe from warming beyond 1.5°C (2.7°F) above preindustrial levels, according to a new study. The research, led by scientists at the International Institute for Applied … Read More

Early Heat Wave Bakes India, Sign of What’s to Come

Early Heat Wave Bakes India, Sign of What’s to Come

Temperatures across northern India, including the capital New Delhi, are set to soar well above 100°F (37.8°C) through the weekend and into next week thanks to a pre-monsoon heat wave that has set in somewhat earlier than normal. Such heat waves are expected to become both more common and more intense as the world warms from the continued buildup … Read More

Carbon Emissions Factor Into Major Oil Sands Shakeup

Carbon Emissions Factor Into Major Oil Sands Shakeup

As global companies abandon the Canadian oil sands at a time of low oil prices and huge losses, some of them are also concerned that producing one of the world’s most carbon-laden fossil fuels may be bad business in a warming world. A wave of sell-offs began last year when Murphy Oil and Norway’s Statoil decided to pull out of the oil sands. Royal… Read More

Americans Used A Lot Less Coal in 2016; Here’s Why

Coal use fell last year for the third year in a row — after slight increases in 2012 and 2013 — and has been steadily declining in the U.S. since it peaked a decade ago, according to U.S. Energy Information Administration data. The ongoing decline is occurring even as the Trump administration promotes coal as a way to boost energy independence and… Read More
