UN climate change panel to be warned over reports
Conducted by a committee of representatives from the world's leading scientific bodies, the analysis is expected to recommend a number of changes to the way the IPCC compiles and checks its extensive 1,000 page reports.
The committee, which is made up of scientific organisations that form the InterAcademy Council, is also expected to recommend changes to help the IPCC keep its reports, which take around six years to complete, more up to date with current science.... The IPCC has been under scrutiny after it admitted making an error in its 2007 report, that stated Himalayan glaciers could melt to a fifth of current levels by 2035 - a statement that was wrong by over 300 years.... Speaking ahead of his lecture, he said: "The IPCC has not sufficiently adapted to the changing science and politics of climate change, nor to the changing expected and demanded role of science and expertise in society.
"The IPCC's approach of seeking consensus obscures and constricts both scientific and wider social debates about both knowledge-driven and value-driven uncertainties that surround climate change politics." ...

Coffee threatened by beetles in a warming world
A tiny insect that thrives in warmer temperatures -- the coffee berry borer -- has been spreading steadily, devastating coffee plants in Africa, Latin America, and around the world.... The beetle is a relatively recent problem in Ethiopia and Latin America, where most Arabica coffee is grown. A field survey of Ethiopia's coffee-growing regions conducted in the late 1960s found no trace of the beetle, but in 2003 researchers reported that the pest was widespread.... Until recently, the coffee berry borer was confined to just a few regions in Central Africa. But since the 1980s, the beetle has gradually spread to every coffee-growing region except Hawaii, Nepal, and Papua New Guinea. Juliana Jaramillo, a biologist at Kenya's International Center of Insect Physiology and Ecology, suspects temperature increases are to blame. ...

Pursuing the mystery herring loss near Nova Scotia
Scientists from the Bedford Institute of Oceanography are on a mission to find out why herring fishermen in Nova Scotia are reporting fewer and smaller fish this season.
The researchers are using sounders and sonars to count the number of herring in an area known as the German Bank, off the southwestern coast of Nova Scotia.
The count may help explain why the catches have been coming up smaller this year.
"When the fishermen don't land fish, people think that there may not be fish," said Gary Melvin, a research scientist. "There can actually be fish. But we want to be sure, one way or the other."
Some fishermen said they believe the catches are smaller because the fish are avoiding warmer water temperatures near the surface and diving deeper, thereby eluding the large nets used to catch them.

Avoiding warmer temperatures would be a smart survival strategy.

Pee is for power: Your electrifying excretions
Urine might not pack the punch of rocket fuel, but what it lacks in energy density it makes up for in sheer quantity. It is one of the most abundant waste materials on Earth, with nearly 7 billion people producing roughly 10 billion litres of it every day. Add animals into the mix and this quantity is multiplied several times over.
As things stand, this flood of waste poses a problem. Let it run into the water system and it would wipe out entire ecosystems; yet scrubbing it out of waste water costs money and energy. In the US, for instance, waste water treatment plants consume 1.5 per cent of all the electricity the country generates. So wouldn't it be nice if, instead of being a vast energy consumer, urine could be put to use.
That thought occurred to Gerardine Botte, a chemical engineer at Ohio University in Athens, during a discussion in 2002 with colleagues about possible sources of hydrogen for use in fuel cells. ...

Indonesia reaches 'super-extreme level of weather'
Indonesia has been experiencing its most extreme weather conditions in recorded history, meteorologists warned on Wednesday as torrential rains continued to pound the capital.
All regions across the archipelago have been experiencing abnormal and often catastrophic weather, an official from the Meteorology, Climatology and Geophysics Agency (BMKG) said.
"We have reached a super-extreme level of weather this year, the first time in our history, and this is much worse than what we experienced back in 1998, when the La Nina caused extreme weather in the country," Edvin Aldrian warned. ...
