Hotter, drier weather could double water bills in some US cities, study finds‎

Hotter, drier weather threatens to double water bills by midcentury in some cities, according to a Stanford-led study. The research, published in Nature Sustainability, is the first to comprehensively model how climate change, infrastructure investment and household water demand can combine to compound an already growing affordability crisis.

Global warming, increasing wildfire risk threaten viability of some California winery regions‎

The U.S. is the fourth-largest wine-producing country by output volume, and approximately 80% of its production occurs in California. Ever since the 19th century, California's premier wine-growing regions have been the Napa Valley and Sonoma County, thanks to their favorable microclimate. But grape yield and quality are very sensitive to the local environment, which means the climate crisis could shake up California's wine industry.

How tall and short trees can coexist in old growth forests‎

Forests are shaped by light competition. The trees that grow the tallest have access to the most sunlight, blocking the rays and rendering the shaded space around them inhospitable to shorter trees below. In this stem exclusion phase of forest succession, the shorter trees often die. Yet scientists have observed that in old-growth forests, trees of vastly different sizes successfully coexist, proving that reaching the top of the canopy is not the sole winning strategy for survival in a forest environment.
