The appeal of shortwave, geoengineering is in it’s purportedly rapid, remediation impact (although no global experiments have been conducted yet). However, the combined climate impact of GHG increases with a geoengineered reduction in shortwave radiation is not known, but, it is feared, could result in environmental “winners” and “losers”–meaning some regions of the planet could experience severe drought, and even increased conflict over water resources.

A 150 lb feral pig has emerged as an unlikely hero after evading capture by the authorities in Florida for an incredible five months.
The pig, dubbed ‘Wilbur’ or the ‘freedom pig’ by supporters, has survived being shot with tranquiliser darts and a taser stun gun since first appearing in a park in the Cove neighbourhood of Panama City.
Last week, Mary Sittman a follower on the “Pig of the Cove” Facebook group launched to chronicle the pig’s adventures asked, “Is the pig a symbol of our desire to live free of government controls?”

The Red-billed Oxpecker is not an endangered species in the CITES lists but poisoning had wiped it out in certain livestock farming areas of South Africa. Now, with a little help, the Oxpecker is re-establishing itself.
The Red-billed Oxpecker is a member of the starling and myna family Sturndidae. It is native to the Savannah of sub-Saharan Africa, from the Central African Republic east to Sudan and south to northern and eastern South Africa.
It is basically an insect eater, but gets its name from its habit of feeding on ticks and other insects living on the hides of large animals. While it is claimed that it can eat up to 100 engorged ticks a day this is often secondary as its favourite food is blood which it sources by opening tick bites with its beak. It is even claimed it will stop wounds from healing to ensure an ongoing supply of blood.

Scientists at Columbia University have discovered that a rock found in the Middle East can be used to soak up carbon dioxide at a rate high enough to significantly slow global warming.
The team found that when the rock, known as Peridotite, comes into contact with carbon dioxide it converts the gas into harmless minerals such as calcite. They have also worked out a way to ’supercharge’ the naturally occurring process to a million times its normal speed to grow enough of the mineral to permanently store 2 billion or more tons of carbon dioxide annually. This equates to an astonishing 7 per cent of the total global carbon emissions from human activity each year.

Scientists have created a new material that could dramatically increase the efficiency of solar cells, by literally capturing every color of the rainbow.
Whereas other materials only catch a small range of light frequencies, and therefore only a small fraction of the potential energy, the new invention is capable of absorbing all the energy contained in sunlight. According to team leader, Prof. Malcolm Chisolm, “There are other such hybrids out there, but the advantage of our material is that we can cover the entire range of the solar spectrum.”
