Study Links Climate Change to Increased Severity of Los Angeles Wildfires

US
Published:

A recent study has underscored the significant impact of climate change on the ferocity of wildfires in Los Angeles, revealing that conditions fueling these devastating incidents were approximately 35 percent more likely due to global warming caused by fossil fuel emissions. The report, published by World Weather Attribution and led by researcher Clair Barnes of Imperial College London, analyzed how human-driven climate change has contributed to reduced rainfall, dried out vegetation, and coupled dangerous drought conditions with powerful Santa Ana winds.

The catastrophic wildfires that erupted in early January resulted in at least 29 fatalities and the destruction of over 10,000 homes, marking the most destructive fire season in the city's history. The study highlighted that drought conditions have increasingly persisted into winter, raising the likelihood of fires igniting during intense Santa Ana winds, which can rapidly escalate small fires into deadly infernos.

Investigators are also looking into the role of Southern California Edison in igniting one of the fires, the Eaton Fire. Although the study did not delve into the direct causes of the fires, it stressed the ever-increasing threat posed by climate change, warning that without a swift transition from fossil fuels, California will continue to face hotter and drier conditions, exacerbating wildfire risks.

Looking forward, the researchers estimate that under current climate projections, similar fire-weather events could increase by another 35 percent by 2100 if global warming reaches 4.7°F above pre-industrial levels. The findings also noted a concerning trend of diminished rainfall during critical months, leading to persistently dry and flammable conditions.

Walgreens Stops Dividend Payments for First Time in 92 Years Amid Financial Challenges

Walgreens Boots Alliance has announced the suspension of its quarterly dividend payment to shareholders, marking the first time in 92 years that the company has opted not to distribute cash dividends. The decision, reported on January 30, 2025, comes as the Deerfield-based retail pharmacy faces ongoing financial difficulties. In an effort to streamline operations, Walgreens plans to close approximately 1,200 stores over the next three years, including locations in Chicago. The company has been implementing cost-cutting measures, which include recent layoffs in Illinois and other regions. According to Walgreens, the suspension of dividends is designed to assess and refine its capital allocation policy as part of a broader turnaround strategy. A company release emphasized that cash needs associated with litigation and debt refinancing critically influenced the decision. Walgreens reported a substantial net loss of $265 million in the first quarter of this year, in stark contrast to a loss of $67 million in the same quarter the previous year.

Costco to Raise Hourly Wages for US Workers to Over $30

Costco Wholesale has announced plans to increase hourly pay for most of its U.S. store workers to over $30, according to a memo distributed to employees this week. The wage hike will implement a $1 increase annually for the next three years, beginning with a rise to $30.20 in the first year. Additionally, workers at the bottom of the pay scale will see their wages increase by 50 cents to $20. This decision comes amid contract negotiations between Costco and the Teamsters union, which represents over 18,000 employees. The union recently revealed that 85% of its members voted in favor of a nationwide strike as talks approach a January 31 deadline. Costco emphasized in the memo, signed by CEO Ron Vachris, that the changes would ensure that their hourly wages and benefits continue to surpass those offered by competitors in the retail industry. As labor relations become increasingly contentious across various sectors, this move may help Costco maintain its workforce and improve employee morale.

New Orleans Archbishop Fires Food Bank Leaders Amid Abuse Settlement Dispute

The Archbishop of New Orleans, Gregory Aymond, has removed top leaders of Second Harvest, a church-affiliated food bank, after they allegedly resisted pressure to contribute $16 million towards settling claims of child sexual abuse against clergy. The dismissals, announced on January 30, include board chairperson Bert Wilson and President Natalie Jayroe, who served for 19 years. The former leaders contend that they were forced out for refusing to allocate funds intended for anti-hunger efforts to the church’s bankruptcy settlement. According to various sources, Second Harvest is a non-profit governed independently, although tied to the archdiocese. Aymond’s letter did not detail reasons for the firings, but he assured that operations at Second Harvest would not be affected. Critics, including former committee chair James Adams, argued that Second Harvest should not be liable or expected to contribute to settlements as it does not directly engage with children in the church's context. The archdiocese filed for bankruptcy in May 2020 to handle over 500 abuse claims against its clergy.
