Over the past 10 years, the number of plant species on European mountain tops has increased by five-times more than during the period 1957-66. Data on 302 European peaks covering 145 years shows that the acceleration in the number of mountain-top species is unequivocally linked to global warming.

A new study has revealed for the first time the last 500-year flood history of the Mississippi River. It shows a dramatic rise in the size and frequency of extreme floods in the past century—mostly due to projects to straighten, channelize, and bound the river with artificial levees.

The Dark Zone of Greenland ice sheet is a large continuous region on the western flank of the ice sheet; it is some 400 kilometers wide stretching about 100 kilometres up from the margin of the ice. 

Mitsubishi Hitachi Power Systems (MHPS) and Carnegie Mellon University (CMU) today announced the release of the 2018 Carnegie Mellon Power Sector Carbon Index, at CMU Energy Week, hosted by the Wilton E. Scott Institute for Energy Innovation. The Index tracks the environmental performance of US power producers and compares current emissions to more than two decades of historical data collected nationwide. This release marks the one-year anniversary of the Index, developed as a new metric to track power sector carbon emissions performance trends. 

Some experts have long believed that a massive asteroid was a primary cause of dinosaurs’ extinction some 65 million years ago, but new analysis from a University at Albany psychology professor suggests that the dinosaurs were in trouble long before the asteroid hit.

A research project conceived by a Brandon University (BU) professor on the northward spread of palms has been featured in the prestigious science journal Scientific Reports and on Columbia University’s Lamont Earth Institute State of the Planet blog.

The ability to create clean, safe drinking water using only natural levels of sunlight and inexpensive gel technology could be at hand, thanks to an innovation in water purification.

Remote areas in Canada’s Arctic region – once thought to be beyond the reach of human impact – are responding rapidly to warming global temperatures, the University of Toronto's Igor Lehnherr has found.

A proposal for an electric cargo airship has made it to the second round of a national contest to come up with “the next big thing” that will transform Canada. The brainchild of Dr. Barry Prentice, the proposal pitches the development of a cargo airship transport network that would do for the Canadian North what the railway did for Western Canada 140 years ago.

As many of Hawaiʻi‘s leading water professionals near retirement, there’s an urgent need to train a new local workforce of scientists. That’s happening at the University of Hawaiʻi at Mānoa thanks to ʻIke Wai, a large five-year project funded by the National Science Foundation that aims to understand how water moves and is captured and stored underground in Hawaiʻi. Its main study sites include the Kona and Pearl Harbor aquifer systems.
