Wisconsin cave holds tantalizing clues to ancient climate changes, future shifts
University of Wisconsin–Madison

Even in their dark isolation from the atmosphere above, caves can hold a rich archive of local climate conditions and how they’ve shifted over the eons. Formed over tens of thousands of years, speleothems — rock formations unique to caves better known as stalagmites and stalactites — hold secrets to the ancient environments from which they formed.

The claim a Dutch researcher predicted the February earthquake in Turkey and Syria would happen three days before it occurred is misleading. Despite the accuracy of his prediction, scientists cannot predict when and where an earthquake will occur.

Residents of Southern Turkey were again jolted by a new earthquake Monday, this trembler reported by the U.S. Geology Survey (USGS) as 6.3 in magnitude. News reports state that scores of buildings that were damaged in powerful quakes on February 6 have been further damaged or outright collapsed. Virginia Tech’s Robert Weiss, who studies natural hazards, calls the devastating trio of earthquake “unusual,” but not “impossible.

Past Records Help to Predict Different Effects of Future Climate Change on Land and Sea
Woods Hole Oceanographic Institution

Ongoing climate change driven by greenhouse gas emissions is often discussed in terms of global average warming. For example, the landmark Paris Agreement seeks to limit global warming to 1.5 ⁰C, relative to pre-industrial levels. However, the extent of future warming will not be the same throughout the planet. One of the clearest regional differences in climate change is the faster warming over land than sea. This “terrestrial amplification” of future warming has real-world implications for understanding and dealing with climate change.

Current models of sea level rise suggest the most widespread impacts will occur after sea level has risen by several meters. But a new study finds the biggest increases in inundation will occur after the first 2 meters (6.6 feet) of sea level rise, covering more than twice as much land as older elevation models predicted.
