Swiss glaciers suffer 'disastrous' year of ice loss, threatening water supplies
Summary
Swiss glaciers experienced a disastrous year of ice loss, further reducing an important source of freshwater. Scientists say the speed of the melting is now an expected consequence of accelerating climate change.
The key shift is that extreme glacier loss is becoming a recurring condition rather than

Moth Swarms Sweep Across Australia. That’s Good News.
Summary
Bogong moths, which have declined sharply since the 1980s, are appearing in the thousands across southeastern Australia this spring. The surge has surprised and encouraged scientists who have tracked the species' losses.
The immediate change is a large increase in sightings after decades of decline, suggesting that
