Abstract

The growth rate of the atmospheric abundance of methane (CH4) reached a record high of 15.4 ppb yr−1 between 2020 and 2022, but the mechanisms driving the accelerated CH4 growth have so far been unclear. In this work, we use measurements of the 13C:12C ratio of CH4 (expressed as δ13CCH4) from NOAA’s Global Greenhouse Gas Reference Network and a box model to investigate potential drivers for the rapid CH4 growth. These measurements show that the record-high CH4 growth in 2020–2022 was accompanied by a sharp decline in δ13CCH4, indicating that the increase in CH4 abundance was mainly driven by increased emissions from microbial sources such as wetlands, waste, and agriculture. We use our box model to reject increasing fossil fuel emissions or decreasing hydroxyl radical sink as the dominant driver for increasing global methane abundance.

That's refreshing to hear. Still wouldn't mind them doing expansion packs.

On February 1, 2021, the Myanmar military arrested de facto head of state Aung San Suu Kyi and other elected politicians and declared a national emergency, giving absolute power to commander-in-chief Min Aung Hlaing.

The coup marked a dramatic political backslide in a country that had been moving toward democracy for the past decade, and triggered widespread unrest. Peaceful protests erupted nationally, government workers launched a civil disobedience movement, and millions of students boycotted school.

Over the following months, soldiers and police fatally shot hundreds of protesters and jailed thousands of dissidents. In response, young people began heading to the forests and mountains by the thousands, seeking training in combat warfare.

One of them was Rupa, a recent high school graduate. She had been living with her parents in the central city of Pyin Oo Lwin at the time of the coup, waiting for schools to reopen after a year of COVID-19-related closures so she could start university. But after witnessing the mobilization of the Myanmar public via social media, she decided to put her education on hold and join the anti-junta uprising.

Known as the Spring Revolution, the uprising seeks to remove the military from power and establish a federal democracy; many but not all of its supporters advocate for an armed as well as a nonviolent response. The movement advocates not only for an end to military rule but also for a more inclusive and just society, and a decentralized political system that addresses the long-standing grievances of ethnic minorities across the country.

When we spoke with Rupa in October 2024, she said that she was initially inspired to action by the diversity and energy of the movement, even though her political awareness at the time was limited. “I didn’t fully understand politics, revolution, or armed resistance,” she said. Still, she felt it was the “right time for me to participate and take responsibility for my country.” (To reduce the risk of retaliation against her or her family, she has been given a pseudonym.)

It's silly to use the geographical map of Canada to show election results. Land doesn't vote, people do.

According to provincial data, 193 Albertans have died due to influenza so far this season, surpassing last year's total of 175.

That's the highest death toll since at least 2009.

The previous major peak, in 2022-23, was 123 flu deaths.

"I'm concerned now that after seeing this trend now for three years that this is becoming the new normal," said Craig Jenne, a professor in the department of microbiology, immunology and infectious diseases at the University of Calgary.

When Sara Weaner Cooper and her husband bought their first home in Pennsylvania, they knew they didn't want a perfectly manicured front lawn like their neighbours. They wanted something that was more than just turf – a flourishing, wild meadow home to diverse species of plants and animals.

Weaner Cooper had always wanted to focus on native plants in her lawn and do less mowing, so rewilding their front lawn felt like the right move. But the Coopers' lawn is a different animal than her father's. It's in full Sun and consisted of over 1,500 sq m (16,000 sq ft) of turfgrass – narrow-leaved grasses designed to look uniform that had to be dealt with before a meadow could fully take over.

Rather than rip everything up and live with a drab, brown lawn for months, they decided to try strategically seeding and planting native plants into the existing turf, hoping it would eventually weed the turf out naturally. "It's easier in the sense that you don't need to be beating back as many weeds," explains Weaner Cooper. "The native plants came in so thickly that they outcompeted a lot of the weed pressure that would have been there if we would have just made it brown."

It took about two years, lots of planning, some careful weeding, and some trial and error, but eventually a medley of waist-high native plant species blanketed their vast front lawn.
