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

China, India Become Climate Leaders as West Falters

China, India Become Climate Leaders as West Falters

In the Western hemisphere, where centuries of polluting fossil fuel use have created comfortable lifestyles, the fight against warming has faltered largely due to the rise of far-right political groups and nationalist movements. As numerous rich countries have foundered, India and China have emerged as global leaders in tackling global warming… Read More

Climate Change Was the Epicenter of March for Science

Climate Change Was the Epicenter of March for Science

The roar of the crowd of thousands of scientists and supporters rippled up and down Constitution Avenue like a wave on Saturday. It found two fitting sounding boards on either side of the street. On one side, the Smithsonian, the world’s largest museum and research program. It’s a literal institution in the science community, with its research cut … 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

Scientists: Get Used to Wildfires in a Warming World

Scientists: Get Used to Wildfires in a Warming World

Communities across the Western U.S. and Canada may have to adapt to living with the ever-increasing threat of catastrophic wildfires as global warming heats up and dries out forests across the West, according to a University of Colorado study published Monday. Residents living in neighborhoods adjacent to forests — known as “wildland-urban … Read More

March Was Second Hottest on Record Globally

March Was Second Hottest on Record Globally

The exceptional global heat of the past few years continued last month, with March ranking as the second hottest on record for the planet. It followed the second hottest February and third hottest January, showing just how much Earth has warmed from the continued buildup of heat-trapping greenhouse gases in the atmosphere. March was 2.02°F (1.12°C)… Read More
