EcoUniv Weekend Reads completes six months.
Research – Species: Why are aquatic mammals much larger in size than those on land? The previous thinking was they don’t have the constraints that land-based mammals face. Research in recent years however shows that their large size is a trade-off between trapping enough body heat and finding enough food.

Research – Climate Change: “Greenland’s ice sheet has melted to a point of no return, and efforts to slow global warming will not stop it from disintegrating….. It dumps more than 280 billion metric tons of melting ice into the ocean each year, making it the greatest single contributor to global sea level rise,”
“…widespread retreat between 2000 and 2005 resulted in a step increase in discharge and a switch to a new dynamic state of sustained mass loss that would persist even under a decline in surface melt.”
