Climate change is exacerbating rainfall, flooding and sea-level rises in coastal and low-lying areas. During the past few years, disastrous floods have swept through Lismore in New South Wales, Northern Queensland, and the Great Ocean Road in Victoria. Large waves have pounded beaches, causing erosion in Byron Bay and Wamberal Beach in NSW and Lancelin, Western Australia.

Some 350,000 years ago, the center of New Zealand's North Island appeared much different than the mountainous, scrub-covered landscape it is today. Amid a glacial period, temperatures were colder and conditions harsher. Vast beech and podocarp forests blanketed the region, providing habitat for abundant native birdlife.

As wildflowers go, the mountain jewelflower is demure, clever and quietly unbreakable. It has spread across many of California's iconic landscapes, from Sonoma wine country to the oak-dotted foothills, even over the Sierra Crest, where snow covers the ground during winter.

Highlights from the last week of May, 2026: A key climate tipping point is disrupting the Arctic Ocean food chain (more of a lowlight, I guess). Scuba-diving tourism may not be the benefit to coral reef systems that we once thought, and might actually be unsustainable. And an experimental mRNA vaccine showed promising results against strains of Ebola.
