Over 2006 to 2010 a prolonged drought, unprecedented in modern documented history, caused a farming collapse in Northeastern Syria. Winter rainfall in the otherwise green & productive ‘Fertile Crescent’ decreased by at least a third in Syria (and up to … Continue reading →
The second part of the new IPCC report, about the impacts of climate change, has been released on Monday. Across the globe dutiful journalists filled the headlines of their newspapers – and as they presume most of their readers are … Continue reading →
The identified critical threshold for dangerous climate change saying that the increase in global temperature should be below 2 degrees Celsius seems not to have helped the climate negotiations so far. New research from the University of Gothenburg and Columbia … Continue reading →
Is Earth really a sort of giant living organism as the Gaia hypothesis predicts? A new discovery made at the University of Maryland may provide a key to answering this question. This key of sulfur could allow scientists to unlock heretofore hidden interactions between ocean organisms, atmosphere, and land — interactions that might provide evidence supporting this famous theory.

Study of last 2 decades shows growing happiness gap between wealthy Chinese and the poorest, reflecting rising unemployment and deteriorating safety net, according to economist Richard Easterlin.
Despite an unprecedented rate of economic growth, Chinese people are less happy overall than they were two decades ago, reveals timely new research from Easterlin, one of the founders of the field of “happiness economics” and namesake of the Easterlin Paradox.
Biodiversity hot spots — the world’s biologically richest and most threatened locations on Earth — and high biodiversity wilderness areas — biologically rich but less threatened — are some of the most linguistically diverse regions on our planet, according to a team of conservationists.
Eating is actually a big word for the marine worm Olavius algarvensis, since the worm completely lacks a digestive system. Over the course of evolution the worm has gathered millions of symbiotic bacteria that have found a home under its … Continue reading →
The second-largest mass extinction in Earth’s history coincided with a short but intense ice age during which enormous glaciers grew and sea levels dropped. Although it has long been agreed that the so-called Late Ordovician mass extinction — which occurred about 450 million years ago — was related to climate change, exactly how the climate change produced the extinction has not been known. Now, a team led by scientists at the California Institute of Technology (Caltech) has created a framework for weighing the factors that might have led to mass extinction and has used that framework to determine that the majority of extinctions were caused by habitat loss due to falling sea levels and cooling of the tropical oceans.

The past few tens of millennia were hard times for the megafauna of the world. Hundreds of big-bodied species—from the mammoths of North America to the 3-meter-tall kangaroos of Australia to the 200-kilogram-plus flightless birds of New Zealand—just disappeared from the fossil record. A new, broad analysis continues the century-long debate over the loss of the big animals, coming down on the middle ground between blaming migrating humans for wiping them all out and climate change alone for doing them in.
