Shock decline in flying insects across Germany: report
The mass of flying insects in parts of Germany has fallen by three-quarters in the last 27 years. Since the territories sampled were all nature reserves in some way protected from pesticides and other disturbance, the implications are alarming: winged insects may be flying to oblivion across much of Europe.
The cost to natural ecosystems and to human economies could be devastating. Insects pollinate 80 per cent of wild plants, feed on species that could otherwise become pests, recycle plant and animal waste, and are themselves food for 60 per cent of birds. One calculation places the value of wild insect pollination at $57 billion a year in the United States.Continue Reading...

War and warming hit Jordan water supply
Hydrologists and climate scientists have just calculated the future of one of the world’s most celebrated waterways, the River Jordan. Their conclusion is that the outlook is poor − and getting poorer.
If humans continue to burn fossil fuels at an ever-increasing rate, then rainfall will diminish by 30 per cent, average temperatures will rise by 4.5 C, and the flow from the Jordan’s most important tributary could fall by 75 per cent. The frequency of droughts will increase threefold, to recur almost every yearContinue Reading...

Scientists warn that global warming is affecting four-fifths of ecological processes vital to ecosystems.
Climate change has already begun to alter the world’s ecosystems – at sea, in rivers and lakes, and in the forests and meadows on land, according to an international team of scientists.
They have identified 94 vital ecological processes that support healthy ecosystems, and have found that more than 80 per cent of them are already affected by global warming.Continue Reading...
Forest species help trees to absorb carbon
Posted May 6, 2016
The ability of forests to absorb carbon is strongly affected by the mix of trees and the other creatures that inhabit them.
