In a landmark report to Alberta’s energy regulator, a panel of experts has concluded that odours from a controversial tar sands processing plant are linked to human health impacts.

The report, which was published [March 31, 2014], examined the emissions from Baytex Energy’s Peace River plant, which has been the subject of a number of health complaints from local residents over the last few years.

The situation has been so bad that seven families have been forced to leave.

In a breakthrough, scientists have developed a new low cost, efficient and environment-friendly solar cell that uses tin instead of the hazardous lead.

Researchers from Northwestern University are among the first to create a solar cell that uses a structure called perovskite, with tin as the light-absorbing material instead of lead.

"Exculding the use of lead is a quantum leap in the process of creating a very promising type of solar cell called a perovskite," said Mercouri G Kanatzidis, an inorganic chemist with expertise in dealing with tin.

You want to know what the biggest obstacle to dealing with climate change is? Simple: time. It will take decades before the carbon dioxide we emit now begins to have its full effect on the planet’s climate. And by the same token, it will take decades before we are able to enjoy the positive climate effects of reducing carbon-dioxide emissions now.
