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

We Just Breached the 410 Parts Per Million Threshold

We Just Breached the 410 Parts Per Million Threshold

The world just passed another round-numbered climate milestone. Scientists predicted it would happen this year and lo and behold, it has. On Tuesday, the Mauna Loa Observatory recorded its first-ever carbon dioxide reading in excess of 410 parts per million (it was 410.28 ppm in case you want the full deal). Carbon dioxide hasn’t reached that … 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

New Posters Imagine National Parks in 2050; It’s Not Pretty

New Posters Imagine National Parks in 2050; It’s Not Pretty

National parks are at the front lines of climate change. The creep of change is playing out in places that Americans have set aside to be preserved for the enjoyment of future generations. A new poster series takes the landscapes that have inspired countless road trips and daydreams of summer vacation and imagines what they’ll look like in 2050 if… 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
