Dusty rainfall records reveal new understanding of Earth’s long-term climate
Ancient rainfall records stretching 550,000 years into the past may upend scientists’ understanding of what controls the Asian summer monsoon and other aspects of the Earth’s long-term climate. Milankovitch theory says solar heating of the northernmost part of the globe drives the world’s climate swings between ice ages and warmer periods. The new work turns Milankovitch in its head by suggesting climate is driven by differential heating of the Earth’s tropical and subtropical regions.

We feel the temptation of universal cheap goods as a right, but the environment pays the cost.
How the Great Barrier Reef won over corporate Australia
Great Barrier Reef Foundation chairman and businessman John Schubert always considered himself an environmentalist, but it was only when he snorkelled on the Great Barrier Reef for the first time in 2003 that he was truly won over by one of the natural wonders of the world.
Who is the group awarded $443m to save the reef? [PAYWALL]
The largest government grant for the protection of the Great Barrier Reef has been awarded, without tender, to a tiny foundation with no details on why.

Synergy accused of abusing market power on solar
The electricity provider has been accused of poaching applicants who want to purchase solar panels off private installers.
How greener grids can stay lit
Without careful management, distributed energy resources have the potential to cause unreliable power delivery, or even outages, and lead utility companies to overcharge customers. A new index will help ISOs and utilities account for uncertainties introduced by both the electricity market and DERs so utility companies can balance the distribution grid and find the fairest customer rates.
Fukushima radioactive particle release was significant says new research
Scientists say there was a significant release of radioactive particles during the Fukushima-Daiichi nuclear accident. The researchers identified the contamination using a new method and say if the particles are inhaled they could pose long-term health risks to humans.
Wood to supercapacitors
Carbon aerogels are ultralight, conductive materials, which are extensively investigated for applications in supercapacitor electrodes in electrical cars and cell phones. Chinese scientists have now found a way to make these electrodes sustainably.

Some like it hot!
Ecologists have no doubt that climate change will affect the earth’s animals and plants. But how exactly? This is often hard to predict. There are already indications that some species are shifting their distribution range. But it is much less clear how individual animals and populations are responding to the changes. Scientists at the UFZ have been studying nocturnal desert geckos to see how they are adapting to climatic changes.
New study highlights opportunity to restore abundance to Hawaiian reef fisheries
A recently published study, led by researchers at the University of Hawai’i at Manoa, identified areas in the Hawaiian Islands that would provide the greatest increase in coastal fishery stocks, if effectively managed.
Imminent extinction of northern white rhinoceros motivates genetic recovery efforts
Earlier this year, the last remaining male northern white rhinoceros (NWR) died in captivity, nearly cementing the fate of this subspecies for extinction. In the wild, continuing threats of poaching, habitat destruction, and small population size have contributed to the rhinos’ status as critically endangered. Yet, novel conservation efforts that make use of cryopreserved genetic material could save the NWR, and other threatened species, from extinction.
