We Can’t Hide From Global Warming’s Consequences

Over the past few months, heat records have broken worldwide.

In early July, the temperature in Ouargla, Algeria, reached 51.3°C (124.34°F), the highest ever recorded in Africa! Temperatures in the eastern and southwestern U.S. and southeastern Canada have also hit record highs. In Montreal, people sweltered under temperatures of 36.6°C (97.88°F), the highest ever recorded there, as well as record-breaking extreme midnight heat and humidity, an unpleasant experience shared by people in Ottawa. Dozens of people have died from heat-related causes in Quebec alone.

Permafrost and Wetland Emissions Could Cut 1.5°C Carbon Budget ‘by Five Years’

By Robert McSweeney

Emissions of CO2 and methane from wetlands and thawing permafrost as the climate warms could cut the "carbon budget" for the Paris agreement temperature limits by around five years, a new study says.

These natural processes are "positive feedbacks"—so called because they release more greenhouse gases as global temperatures rise, thus reinforcing the warming. They have previously not been represented in carbon budget estimates as they are not included in most climate models, the researchers say.

Trump’s Supreme Court Pick: What’s at Stake for Science and the Environment?

By Ken Kimmell

Battle lines over President Trump's nominee for a new U.S. Supreme Court justice are now being drawn, as they should be, over crucial issues such as a woman's right to choose, health care, immigration, civil rights and criminal justice. In past nomination fights, little attention has been paid to the court's role in shaping environmental law and science-based regulation. But it would be a major mistake to overlook these issues now. The Supreme Court has an enormous impact on how U.S. environmental laws are interpreted and enforced, and a new justice could tip the balance against science-based rules on climate change, clean air and clean water.

Oil and Gas Operations Release 60 Percent More Methane than EPA Thought, Study Finds

A study published Thursday found that U.S. oil and natural gas operations release 60 percent more methane than currently estimated by the U.S. Environmental Protection Agency (EPA), according to a press release from the Cooperative Institute for Research in Environmental Sciences (CIRES) at University of Colorado, Boulder.

Video: How Beef Farmers Can Reduce Their Carbon Footprint

By Daisy Dunne and Tom Prater

The beef industry is currently responsible for 6 percent of annual global greenhouse gas emissions, making it as large a polluter as the construction sector.

Eating less meat is one way to cut beef emissions. However, scientists have also started to look at ways that farmers can reduce the carbon footprint of beef before it reaches the plate.

Healthy Soil: Good for the Farmer, Good for the Planet

Many people believe that if you just focus on soil health, everything else will follow. This principal is prominently featured in a recent New York Times Magazine article, "Can Dirt Save the Earth?" which examines the practicality of regenerative agriculture.

Moises Velasquez-Manoof begins his lengthy piece with John Wick and his wife, Peggy Rathmann, two decades after they bought a ranch in Marin County, California, and began a quest to learn how to sequester carbon in the soil. The couple met with rangeland ecologist Jeff Creque back in 1998, after they noticed their land was quickly losing its vitality and an invasive weed was taking over. Creque suggested that the couple focus on cultivating what they wanted on their land instead of fighting against what they disliked.

Melting Permafrost Emits More Methane Than Scientists Thought

By Alex Kirby

Methane emissions are the source of the greenhouse gas which, after carbon dioxide, probably causes climatologists more sleepless nights than any of the other gases. And now it appears they have quite a lot more to bother them than they had realized.

Methane is reckoned to be at least 30 times more powerful than CO2 at warming the earth, with some estimates putting its potency much higher still. The good news, research has suggested, is that there is far less methane than CO2 in the atmosphere to worry about.

Trump Wants to Eliminate NASA’s Climate Research Programs: These Pictures Show What a Loss That Would Be

By Jeremy Deaton

President Trump's proposed 2019 budget would slash funding for NASA's Earth Science Division, and while his budget hasn't gained traction in Congress, it is an important statement of the administration's priorities. In a nod to his allies in the fossil fuel industry, Trump is calling for the elimination of vital programs that monitor carbon pollution and climate change.

Methane Meltdown: Thawing Permafrost Could Release More Potent Greenhouse Gas Than Expected

A study published in Nature Climate Change Monday shows that thawing permafrost in the Arctic might produce more methane than previously thought. Methane has 28 times the Global Warming Potential (GWP) of carbon dioxide, so the findings indicate scientists might have to reassess how thawing permafrost will contribute to climate change.
